Elbow type head ground wire hanging apparatus

Abstract

The present invention discloses an elbow type head ground wire hanging apparatus, comprising a connector A (2), an operating lever (6), a connector B (7), and a prolongation screw (11). The elbow type head ground wire hanging apparatus is characterized in that: the front end of the operating lever (6) is provided with the connector A (2), the connector A (2) is connected with an electroscope (4) through a connecting line (3), the electroscope (4) is arranged on the operating lever (6), the rear end of the operating lever (6) is connected with the connector B (7), and the connector B (7) is provided with the prolongation screw (11); the head of the connector A (2) is provided with a small operating head (12), the external part of the small operating head (12) is provided with a multifunctional adapter (1) in a matching way; the operating lever (6) is made by an insulating material; the head of the connector B (7) is provided with a small notch (8) and a large notch (13) which are arranged vertically. The elbow type head ground wire hanging apparatus of the present invention has the advantages of simple structure, convenient operation, high efficiency, practicability, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of the electric power industry, and in particular relates to an elbow-shaped head hanging ground wire device for electric box-type equipment cables. Background technique [0002] The grounding wire is a necessary equipment for the operation, maintenance, repair and expansion of the power system line to ensure the personal safety of the construction personnel. It plays a role in protecting the personal and equipment safety in the power system. The reasonable use of it is directly related to the operation and maintenance of the power system. and equipment safety. Grounding is divided into working grounding and protective grounding. The working grounding is usually completed in the construction stage, while the protective grounding is mostly used in maintenance and expansion. This is one of the "safety measures" in the work. [0003] In the power system, when there is a physical connection with the live line o...

Problems solved by technology

But the actual situation is not so simple. In the power grid with mutual supply and reverse, in order to ensure the quality of power supply service and improve the reliability of power supply, another power supply will be reversed to the outlet side of the equipment body switch, which makes the outlet side The grounding switch cannot be closed, and the work cannot be carried out without closed safety grounding. If in order to achieve closed safety grounding and meet the working conditions, more users will be shut down, thus failing to meet the quality of power supply service and reliability of power supply sex

In the prior art, the commonly used wiring devices have the following problems: the structure is relatively complex, the operation is not convenient, the efficiency is low, and there are large safety hazards, which can no longer meet the existing production needs
