Electricity testing switching operation equipment for distribution line

Abstract

The invention provides electricity testing switching operation equipment for a distribution line. The equipment comprises an insulating rod, a functional part fixedly connected to one end of the insulating rod, and a grab handle fixedly connected to the other end of the insulating rod, the functional part comprises a sleeve and a conductive working head; wherein the sleeve comprises an upper working part and a lower working part, one end of the upper working part is fixedly connected with the working head, the lower working part is detachably connected to the other end of the upper working part, the tail end of the lower working part is fixedly connected with the insulating rod, an electroscope is arranged between the upper working part and the lower working part, the electroscope is provided with a contact head, and the contact head is electrically connected with the working head. According to the equipment, an operator can clearly know the electrification condition of the line when switching operation is carried out.

Description

technical field [0001] The invention relates to the field of insulating tools for operating live equipment, in particular to a switching operation equipment for power inspection and switching of power distribution lines. Background technique [0002] Switching operation is often required in the maintenance of power equipment. The main tool used is the switch lever, also known as the gram rod, insulating rod, and insulating pull rod. It consists of three parts: the working head, the insulating rod and the handle. It is used for closing or opening the high-voltage isolating switch, attaching and disassembling the portable grounding wire, and performing measurements and tests. [0003] According to the combination form, the high-voltage switch lever can be divided into the following types: First, the interface-type insulating operating lever is a commonly used insulating lever. The butt screw interface is adopted at the subsections, and the longest can be 10 meters. It can be ...

Problems solved by technology

[0005] Because it is mainly used as an insulating tool for operating live equipment in a short time, such as connecting or disconnecting high-voltage isolating switches, dropping fuses, installing and disassembling portable grounding wires, and for measuring and testing, the existing pull During the switching operation, the brake lever did not indicate whether the line was live or not. On the one hand, the operator did not know whether the switching operation was successfully completed. On the other hand, it was easy to cause corresponding safety hazards and personal accidents.
