Technical Field

The invention relates to the technical field of electrical equipment, in particular to equipment allowing identification and safe and reliable processing of electrical equipment.

Background

The use of cable identification devices is well known in the art. Prior to repair or modification of an existing transformer or associated secondary cable, the wireworker must first determine the required equipment to be used. Typically, the trolley operator must determine which specific cables among the plurality of secondary cables in the transformer lead to the meter base of a given building or structure, and which specific cables among the plurality of secondary cables that are not found or unearthed in the building, dig pits, lead to the meter base of the building or structure, or connect the desired cables.

To accomplish this cable identification, a linesman is typically required to systematically separate the secondary cable from a given transformer to determine which building or structure the secondary cable is powering. This determination is made upon detection of a cessation of current flow to the particular building structure. Such an approach can have significant consequences as the inhabitants of several buildings will experience brief power outages until the required cable and associated building or structure are determined, resulting in potentially disruptive service outages, loss of unsaved computer files or general household inconvenience.

In addition, while it is possible to identify the termination of a primary cable from one transformer to another, it is difficult to identify the particular phase of an unearthed or bare primary cable in an excavation, where such identification is determined for splicing. New auxiliary users are served in additional transformers.

Electrical identification devices are known in the art. The equipment used to identify the primary and secondary cables is very bulky, heavy, cumbersome, overly complex to implement, and very expensive. Thus, these devices are rarely used by linemen and may not be released by their electrical service company as standard devices to linemen. In addition, the overall cumbersome or awkward nature of such devices makes deployment or implementation very difficult. This difficulty can be amplified by the close proximity of the auxiliary cables. Moreover, moving such equipment into an excavated pit or trench is certainly a difficult task, with significant risks if dropped on live cables or other linemen.

It is also possible to identify an embedded cable by applying a specific frequency to the cable and then detecting the magnetic field generated by the signal from the surface. In this way, the frequency of the signal is selected so that the generated magnetic field can be detected at the surface level and therefore excavation is not required.

Unfortunately, such frequencies may be transferred to other cables due to inductive and capacitive leakage. This often results in distortion of the magnetic field, resulting in incorrect cable positioning and possibly even identification of the wrong cable.

Another such identification method is to apply a removable label to the cable. These tags are often difficult to read, especially in the low light range of a pit.

Furthermore, the cable marking systems found in the prior art do not provide a means for a lineman to manipulate the cable. Separate methods must be used to connect, disconnect or manipulate the cables in addition to any indicator marking systems on the cables. The present invention overcomes this drawback by providing a combination label system and apparatus for manipulating cables.

In addition, in addition to providing cable identification and handling, the present invention can also be used to handle dead-space or load break bends without any interference with normal operation. The prior art does not provide any solution that allows a linesman to attach equipment to a dead-point or load break elbow that can be used to manipulate the dead-point or load break elbow and that does not interfere with the normal operation of the dead-point break or load break elbow.

It is therefore apparent that there is a need for an apparatus and method for cable identification that is fast, inexpensive, lightweight, personal portable, electrically benign, easy to read in low light conditions and easy to implement, wherein secondary cables including grounded secondary cables/conductors can be identified without the above-mentioned disadvantages.

The present invention meets these needs by providing a user with a small, easily identifiable preset cable characteristic that can be clipped onto a cable under any lighting conditions without the need for a support device that allows a lineman to operate the electrical device to which the clip is clipped.

Disclosure of Invention

The present invention provides a clip device that can be removably attached to an electrical device so that the device can be manipulated without requiring a power outage. The electrical devices are connected by a flexible but rigid flange which is partially wrapped around the devices. Embodiments have markings to indicate electrical information such as line voltage, phase identification and line identification. The present invention can be used by linemen and other personnel to safely operate electrical equipment without first de-energizing the line. The present invention allows a cable to be operated by a single person using a full grip or shot gun joystick operated tool.

In a preferred embodiment of the invention, an electrical equipment clamp is provided with markings indicating necessary information about the cable to which it is connected. The preferred embodiment also has an attachment for manipulating the cable through the a-gun joystick and an attachment for securing a lanyard or identification tag. A lanyard attachment can be used to secure a destination or GPS tag to an electrical device to which the present invention is attached. This embodiment has a detachable tag indicating line voltage and phase information. The tags can be removed so that the remaining tags properly indicate the electrical characteristics and the identity of the cable to which the electrical device clip is attached. This example is made from a highly visible oil and heat resistant polymer.

Another embodiment of the present invention is provided for use with a break elbow and a load break elbow. This embodiment is firmly fitted on the breakpoint and load break elbow and has an a-barrel muzzle ring so that the breakpoint or load break elbow can be safely manipulated without power interruption. The front baffle covers the deadlock release-preserving assembly. The capacitor test point openings allow a user to test the capacitor without deleting the present invention. This embodiment is made of a highly visible, reflective and luminescent heat and oil resistant polymer.

Likewise, the terms "embodiments of the invention," "alternative embodiments," and "exemplary embodiments" do not require that all embodiments of the apparatus include the discussed feature, advantage or mode of operation. The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

For clarity, all similar elements will have the same number and label in each image. The terms "electrical device clamp", "cable clamp", "dead-angle elbow clamp", "load-break elbow clamp", "the invention" and "the invention" may be used interchangeably. In addition to the functions, features, components and capabilities of the devices already discussed in this specification, the present invention may have, but is not limited to, the following features included in the description set forth herein.

This section discusses several preferred embodiments of the electrical equipment clamp. However, the present invention is not limited to these examples. The electrical equipment clamp according to the invention is any clamp that can be removably attached to electrical equipment, such as a cable, dead-end bend or load break bend, so that the equipment can be safely operated without powering down the equipment.

Reference is now made to fig. 1 to 4. Detailed description figures 1-8, which will be discussed together, illustrate an embodiment of an electrical equipment clip designed to be attached to a cable. This embodiment has an electrical equipment clamp body (100) that is partially wrapped around a cable. A profiled flange (101) attached to the device clip body (100) detachably secures the electrical device clip to the cable. The profiled flange (101) is strong enough to grip the cable sufficiently so that the electrical equipment clamp can be held firmly in place and not accidentally moved when the electrical equipment clamp is used to manipulate the cable. The shaped flange (101) can be broken off from the electrical equipment clip so that the clip can be removed from the cable. The flange (101) is made of a plastics polymer material which is easily broken and removed if necessary.

The embodiment also includes an a-gun ring (103) for connection to a steering device such as a device gun or a full grip. The stick and grip of the gun are versatile multi-purpose tools that are commonly used by electrical patrols to safely operate powered equipment due to their insulating capabilities. The shot-gun-rod ring (103) is a generally circular region of the body with sufficient strength to allow the a-gun rod or grip to be fully attached to the cable clamp. The linesman may use the stick ring of the bullet gun to pick up, move, connect, disconnect or perform other types of operations (103) without having to disconnect the power supply to the cable to which the clip is connected. Furthermore, the barrel ring (103) allows less people to handle the cable. Typical line handling operations may require up to four people, but with the present invention, a single person may perform the handling process.

The invention also includes a lanyard loop (104) that can be used to attach an identification device or lanyard to an electrical equipment clip. To comply with regulatory requirements, certain identification devices need to be connected to a cable. The lanyard ring (104) provides a connection point for a compliance-required identification device and other information devices (e.g., destination tag and GPS tag devices) on the body of the electrical device clip (100). These identification devices are used to correctly identify the cable to which the electrical device clamp is connected.

A removable information sheet (102, 105) is provided to easily convey information to the cardholder for engaging the cable. Some detachable information tags are phase identification tags (102) that provide information about the phase of the cable, while other detachable information tags are voltage identification tags (105) that provide information about the voltage of the cable. The phase information displayed on the phase identification tag (102) is displayed as an integer. The voltage information (105) displayed on the voltage identification tag is displayed in units of volts, kilovolts, or megavolts. Certain embodiments of the present invention have an information tag that conveys additional information about the cable in addition to phase and voltage.

A removable piece of information (102, 105) is initially attached to the electrical device clip but later detached leaving only indicia conveying the correct information about the particular cable. In an example of use, one embodiment of the present invention has a 1, 2 or 3 representative phase of the removable information piece (102, 105), and a 12 or 21 kilovolt rating when connected to the cable kilovolt of phases 1 and 12, the phase information tags (102) 2 and 3 and the kilovolt information tag (105) 21 are separated. The remaining information tags (102, 105) correctly indicate that the cable to which the electrical equipment clamp is attached has a voltage of 1 phase and 12 kilovolts.

Other embodiments of the invention have voltage identification tags (105) of 34.5kV and 4kV, while other embodiments of the invention have voltage information tags (105) of 14.4kV and 5 kV.

Reference is now made to fig. 1 to 4. Fig. 9-16, which will be discussed together, illustrate an embodiment of an electrical equipment clamp designed to attach to a load break and a dead-angle bend. Load breaks and dead-end bends are typically separable connectors for terminating insulated cables and connecting them to some form of electrical equipment or other cable.

The embodiment has an electrical equipment clamp body (100), and the electrical equipment clamp body (100) is firmly assembled on a broken end or a broken elbow through partially wrapping the broken end or the broken elbow. A profiled flange (101) attached to the equipment clamp body (100) removably secures the electrical equipment clamp to a dead center or load break elbow. The shaped flange (101) is sufficiently rigid to adequately grip the dead angle or load-bent elbow so that when the electrical equipment clamp is used to manipulate the dead angle or load-bent elbow, the electrical equipment clamp is securely held in place and does not move accidentally. The profiled flange (101) can be broken off from the mounting clip of the electrical apparatus for removal from the dead angle or load bend and is made of a plastics polymeric material which can be conveniently broken off and removed when required.

This embodiment of the invention also includes a-a gun rod ring (103) for connection to an operating device such as a device gun rod or full grasper. The shot gunrod ring (103) is a generally circular region of the body which is strong enough to allow the a-shot gunrod or the entire grip to be attached to the cable clamp. The linesman can pick up, move, connect, disconnect or perform other types of operations using the barrel collar (103) on the electrical equipment clamp without having to de-energize dead corners or loads of the retaining clamp to break the elbow. In addition, the bullet lance ring (103) can reduce dead angles of hand manipulation or broken elbows. A typical broken head or reduced weight elbow manipulation operation may require up to four people, but with the present invention, a single person may perform the manipulation process.

This embodiment of the invention also includes a front bezel (106) that covers the dead end bail or bail assembly. The front bezel (106) is an elongated portion of the electrical equipment clamp body (100) at one end of the electrical equipment clamp. A shroud (106) covers and protects the hook or hook assembly so that the hook is not damaged when the electrical equipment clamp is used to maneuver dead corners or load broken bends.

This embodiment of the invention also includes a capacitor test point opening (107), which is an opening in the electrical equipment fixture body (100) through which the dead-space or load break elbow test point passes. Breakpoint or load breakpoint elbow test points are commonly used to indicate whether an elbow is powered on and for fault indication. The capacitor test point openings (107) allow dead corners or load break elbow test points to remain visible and functional when the electrical equipment clamp is connected.

Embodiments of the present invention visually conform to federal, state or local specifications and compliance requirements. The color of the electrical equipment clip is a visual feature that must meet the above specifications and compliance requirements. In one embodiment of the invention, the electrical equipment clip is bright yellow, so that it is easy to view, meets regulatory requirements, and can be quickly placed in dark or dim conditions.

The size of the letters printed on the electrical equipment clip is another visual feature that must meet certain specifications and compliance requirements. In one embodiment of the invention, all letters, numbers and symbols printed on the electrical equipment clip will be readable over a distance of four feet or more. Must be readable from four feet away or larger, and the numbers and symbols include letters, numbers and symbols located on the removable message cover (102, 105) or any of the main body electrical equipment clip (100) where the letters, numbers and symbols are located. In certain embodiments of the invention, the numbers and symbols may also be read at a distance of four feet or more by any identification device attached to the electrical equipment clip by a lanyard ring (104) or by letters printed on the lanyard.

Embodiments of the present invention are constructed of materials having important properties including, but not limited to, non-electrical conductivity, Ultraviolet (UV) resistance, reflectivity, heat resistance, and oil resistance. Certain embodiments of the present invention have a combination of the above characteristics as desired for a particular application. For example, embodiments of the present invention provide an electrical equipment clamp that is resistant to ultraviolet light and oil. Other embodiments of the present invention provide additional material properties required for compliance, safety or utility purposes.

Another material characteristic is flexibility while having the rigidity of some plastic polymers. This material property allows a suitable number of electrical equipment clips to be bent or curved, but still allows the clip to remain connected to a cable, dead-end bend or load break bend without inadvertently falling off.

It is important to note that some embodiments of the present invention are used with components of electrical equipment located above ground, while other embodiments of the present invention are used with components of electrical equipment located below ground. However, it is anticipated that one of the primary applications of the present invention will be for underground cables, particularly those that pass through a utility depot. Another major application is dead-point bending or load break bends. It is expected that by placing the present invention in an underground utility store, the handling of live cables will be safer, more efficient and require less personnel. It is further contemplated that an indirect benefit of the present invention will be cost savings to the utility company that employs the present invention.

As shown in the present specification and drawings, a new electrical equipment clamp has been developed, which is improved over the conventional electrical equipment clamp. The various embodiments of the improved electrical device clip described herein can be used in a variety of applications.

The foregoing exemplary embodiments are not intended to be limiting, but merely possible uses for electrical device clips.

Although certain example apparatus and articles of manufacture have been described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all apparatus and articles of manufacture fairly falling within the scope of the invention either literally or under the doctrine of equivalents.

With respect to the above description, then, it should be recognized that the optimum dimensional relationships for the components of the electrical equipment clamp include variations in size, materials, shape, form, function, and manner of operation and use. Those skilled in the art will readily understand and appreciate, and all equivalent relationships to those illustrated in the figures and described in the specification are intended to be encompassed by the electrical device clip.

Directional terms, such as "front", "rear", "inner", "outer", "lower", "upper", "lower", "side", "vertical", and the like, have been used throughout the description. These terms apply to the embodiments shown and described in connection with the images. These terms are used for descriptive purposes only in connection with the image and do not necessarily apply to the location where the electrical device clip may be used.

Therefore, the foregoing is only as an example of the principles of the electrical device clamp. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the electrical device clamp to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to. Belonging to the range of electrical equipment clamps. While the above description describes various embodiments of the present invention, it should be apparent that the present invention can be readily adapted to suit any configuration where an electrical device clip is desired or needed.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
