Technical Field

The invention relates to the field of electric power engineering safety, in particular to an anti-misoperation device for an isolation baffle of a centrally-mounted switch cabinet.

Background

Provision of safety regulations for electric work (2016) in national grid companies 5.1.9: after the handcart switch is pulled out, whether the isolation baffle is reliably closed or not is observed. When the central switch cabinet handcart is pulled to the maintenance position, the electrified parts such as the upper static contact and the lower static contact in the cabinet can be shielded by the isolation baffle, so that the situation that field operation personnel mistakenly touch electrified bodies to cause personal electric shock accidents is prevented. The isolation baffle plate is controlled to be opened and closed through inclined mechanical connecting rods positioned on two sides in the switch cabinet, when the handcart is pushed to a working position, the two sides of the handcart extrude the inclined mechanical connecting rods, the mechanical connecting rods are pressed down, and the isolation baffle plate is opened; similarly, when the handcart is pulled to the maintenance position, the mechanical connecting rod is lifted, and the isolation baffle is closed. However, in actual field work, an operator easily touches the mechanical connecting rod by mistake during work, so that the isolation baffle is opened, and personal electric shock accidents are easily caused. At present, a method for hanging a mechanical lock on an isolation baffle to prevent the isolation baffle from opening and closing exists, but the hanging lock is arranged on the isolation baffle and is close to an electrified part, so that electric shock danger occurs, and the defect exists.

Disclosure of Invention

The invention aims to provide an anti-misoperation device for an isolation baffle of a centrally-mounted switch cabinet, which can effectively prevent operators from mistakenly touching and mistakenly getting an electric shock.

The invention is realized by the following technical scheme:

the utility model provides a put formula cubical switchboard division bar and prevent mistake opening device, includes: a base; the fixed connecting rod is transversely fixed at the upper part of the base; and the two fixing hooks are respectively arranged at the left end and the right end of the fixing connecting rod and are used for fixing the mechanical connecting rod.

Furthermore, both ends are equipped with telescopic link respectively about fixed connecting rod, the fixed hook corresponds to be installed telescopic link's outer end.

Furthermore, the telescopic connecting rod and the fixed connecting rod are fixedly connected through a knob bolt.

Furthermore, the base is a telescopic base.

Furthermore, the fixed connecting rod is made of glass fiber reinforced plastic epoxy resin.

Compared with the prior art, the invention has the following beneficial effects:

1. the mechanical connecting rod is fixed through the fixing hook, the part of the fixing connecting rod is made of glass fiber reinforced plastic epoxy resin, so that the excellent insulating property is achieved, the overall safety performance of the device is improved, and the misoperation of electric shock of operators can be effectively prevented;

2. the device has simple structure, excellent performance and low investment cost.

3. The device has strong expansibility and wide application, and is suitable for middle-mounted switch cabinets with various voltage levels of 35kV, 10kV and the like.

4. The operation is convenient, and field operators can easily learn and meet the requirements.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-2, the invention provides an anti-false opening device for an isolation baffle of a centrally-mounted switch cabinet, which mainly comprises a base 1 capable of being adjusted in a telescopic manner, a fixed connecting rod 2 transversely fixed on the upper part of the base 1, telescopic connecting rods 3 respectively sleeved on the left end and the right end of the fixed connecting rod 2, and fixed hooks 4 respectively and correspondingly installed at the outer ends of the telescopic connecting rods 3. Wherein, the material of fixed connecting rod 2 is glass steel epoxy, pass through knob bolt fixed connection between telescopic link 3 and the fixed connecting rod 2.

The anti-misoperation device for the isolating baffle of the centrally-mounted switch cabinet has the following specific working process:

after the handcart of the central switch cabinet is pulled to an overhauling position, the device is placed in the switch cabinet, the left and right fixing hooks of the device can firmly fix the mechanical connecting rods at the two sides of the switch cabinet by adjusting the length of the telescopic connecting rod, and then the fixing knobs at the two sides of the fixing connecting rod are screwed down. In the same way, the base is fixed on the ground. Through the anti-misoperation opening device for the isolation baffle, the isolation baffle is always in a closed position when the equipment is in an overhaul state, and the condition that an operator mistakenly touches the electrified space is prevented. The connecting rod part is made of glass fiber reinforced plastic epoxy resin, so that the connecting rod has excellent insulating property and further improves the safety performance of the device.
