Technical Field

The invention relates to the technical field of power equipment, in particular to a joint waterproof high-voltage current transformer.

Background

The principle of the current transformer is similar to the electromagnetic induction principle, and the current transformer is generally used for measurement, protection and other purposes. As one of the current transformers, the high voltage current transformer is mostly specified by a transformation ratio (i.e., a ratio of a primary current to a secondary current), that is, a ratio of the number of turns of a primary winding to the number of turns of a secondary winding. Some current high-voltage current transformers are in open-air service environment, and the connector part of its connection is also exposed outside, can often cause the high-voltage current transformer trouble because of the influence of bad weather, and this not only reduces high-voltage current transformer's life, leads to the maintenance personal to need frequently to overhaul moreover, has wasted a large amount of manpower and materials.

Disclosure of Invention

In order to solve the technical problem, the invention provides a waterproof joint type high-voltage current transformer.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

the utility model provides a connect waterproof formula high-voltage current transformer, includes the casing, sets up the iron core in the casing, corresponds primary winding and the secondary winding that sets up on the iron core, and the casing intussuseption is filled with insulating resin, primary winding, secondary winding are connected with two joints that set up on the outside lateral wall of casing respectively, and the relative both sides department that each connects all installs with slidable mounting's mode symmetry and is used for connecting the waterproof component who accomplishes its junction seal package after the wiring.

Further, every waterproof component of group all includes and uses the joint to pack into the buckle subassembly of a complete seal with the wiring department parcel of joint on two sealed parcel boards and mutual block on two sealed parcel boards on the casing lateral wall as symmetry center symmetry slide, each other.

Further, buckle subassembly is including corresponding port card, the card plug that sets up in two sealed parcel board side departments and mutual block separately, the card plug is the barb form and has certain elasticity.

Further, the bottom of the shell is provided with a grounding base for installation and grounding.

The invention has the beneficial effects that:

compared with the existing current transformer, the invention can seal and wrap the wiring position of the joint after wiring is finished by arranging the sealing wrapping plates which are convenient to clamp or open on two sides of each joint, thereby preventing rainwater from permeating, solving the problems of current transformer faults and reducing the service life of the current transformer caused by the influence of severe weather in the existing current transformer, and simultaneously saving manpower and material resources.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.

As shown in fig. 1 to 5, a waterproof joint type high-voltage current transformer includes a housing 1, the housing 1 is an insulating housing, and a grounding base 10 is disposed at the bottom of the housing 1 for facilitating the fixed installation and grounding of the housing 1. Be equipped with iron core 2 in the casing 1, iron core 2 is square closed structure, and it has insulating resin 5 to fill between iron core 2 and the casing 1, and iron core 2's upper portion is around being put primary winding 3, and the lower part is around being put secondary winding 4, corresponds on the outside roof of casing 1 to be equipped with two and primary winding 3 end to end connection's joint 6, correspond on the outside preceding lateral wall of casing 1 to be equipped with two and secondary winding 4 end to end connection's joint 6. And both sides of each joint 6 are provided with a waterproof component for sealing and wrapping the joint of the joint 6 after the wiring is finished.

Each waterproof component includes two sealed parcel boards 7 of symmetric distribution and sets up the buckle subassembly that just can block each other on two sealed parcel boards 7. The sealing wrapping plate 7 is of a semi-cylindrical structure, and the bottom of the sealing wrapping plate is slidably mounted on the outer wall of the shell 1 through a sliding groove 11. In addition, the upper end portion of each sealing wrap plate 7 is further provided with a sealing shield plate 71 extending inward to further ensure the sealing performance, wherein the sealing wrap plates 7 in the waterproof member on the top wall of the casing 1 are all distributed along the front-rear direction, and the sealing wrap plates 7 in the waterproof member on the front side wall of the casing 1 are all distributed along the left-right direction.

The buckle component comprises a through hole card 8 and a card plug 9 which can be mutually clamped, wherein the card plug 9 is in a barb shape and has certain elasticity. In this embodiment, four port cards 8 and four card plugs 9 are respectively arranged on the sealing wrap plate 7, and are correspondingly mounted on the side walls of two sides of the sealing wrap plate 7 by two screws.

Initially, as shown in fig. 4, each buckle subassembly that connects 6 department is all in the open mode, does not influence the wiring that connects 6, connects 6 wiring completion back, promotes every two sealed parcel boards 7 that connect 6 department and gathers together toward connecting 6, and after the side laminating of two sealed parcel boards 7, card plug 9 just inserts in the opening card 8 that corresponds, because card plug 9 is the design of barb form, just can not take place the pine after two sealed parcel boards 7 laminate and take off. Therefore, the wiring part of the joint 6 is wrapped in a sealing mode, rainwater cannot permeate when raining, and the current transformer fault caused by the influence of severe weather is avoided. When the sealing wrapping plate 7 needs to be detached, the card plug 9 is pressed downwards, so that the card plug 9 and the bayonet in the port card 8 are staggered to realize separation.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
