Problems solved by technology

At present, there are many methods for disassembling and assembling the ground wire, but most of the procedures are cumbersome, inefficient and error-prone
In addition, there are many unfavorable factors in the high-voltage transmission line, such as multiple circuits on the same pole, limited space for high-altitude operations, and difficulties in electrical inspection. Before using the terminal clamp of the traditional portable ground wire, it is necessary to use an electrical inspection rod for electrical inspection in advance, which increases the difficulty of work. time
Electric workers must first wear insulating gloves and use a test rod to conduct an electric test on the power line to be worked. After the test, they must use a high-voltage clamp to ground the high-voltage line. A time difference, during which the equipment may be suddenly electrified due to various reasons such as "enterprise reverse power transmission, switching on", etc., but the electrician is not aware of it, which will lead to the live operation of the electrician and cause electric shock to the electrician
In addition, due to the negligence of the electrical workers, there may be no signs and barriers installed on the maintenance site, and the signs and barriers have no visual warning function, and pedestrians and animals will also cause electric shock accidents if they accidentally enter
There is a big security risk

Abstract

The invention discloses a grounding wire assembly with a real-time electricity testing function. The grounding wire assembly comprises a grounding wire clamp, an insulating operating rod and an electroscope, wherein the grounding wire clamp comprises a clamp head, a grounding wire set connected with the clamp head and a connector, the grounding wire set is connected with a grounding pin, the clamphead comprises a U-shaped part and two elastic clamping plates oppositely arranged on the inner sides of the two side edges of the U-shaped part, and the connector is connected with one side of an opening of the U-shaped part; the upper end of the insulating operating rod is connected with the connector of the wiring clamp, and the lower part of the insulating operating rod is provided with an operating handle; and the electroscope comprises a copper wire and an induction alarm module, one end of the copper wire is connected with the induction alarm module, and the other end of the copper wire is connected with the chuck of the grounding wire clamp. Grounding wire hanging, electricity testing and near-electricity alarm are integrated, and the device is suitable for electricity testing andgrounding functions of electric power lines of 10KV and above.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to an outdoor grounding wire. Background technique [0002] The operation of installing and disassembling the grounding wire in substation operation is a relatively dangerous operation in electrical operations. Accidents in power systems where live wires are connected to the grounding wire are not uncommon. The "Electricity Safety Work Regulations" clearly stipulates that before installing the grounding wire, it is necessary to conduct an electric inspection on the equipment to confirm that the equipment has no voltage. Once an accident occurs, the impact will be great and the consequences will be serious. And it is listed as one of the vicious misuse accidents. Therefore, ensuring the correctness of the installation and disassembly of the grounding wire is an important task for the safe and reliable operation of the substation. [0003] During the ...
