All-in-one device for inspection and discharge

Abstract

The invention discloses an integrated apparatus with electricity verification and electric discharge functions. The integrated apparatus comprises an electricity verification part, an electricity discharge part and an insulating holding part, wherein the electricity verification part comprises an electroscope body, an electricity verification contact and a self-inspection button; the electricity discharge part comprises a barrel body, an electricity discharge contact, a rotary switch, a rotation shaft and a grounding contact; the rotary switch drives the rotation shaft; the rotation shaft pushes the grounding contact to extend out of the barrel body through a cam driving mechanism; an elastic clamping mechanism which can clamp the grounding contact in the barrel body is arranged in the barrel body; and the rotation shaft is also provided with a clamping releasing mechanism which is linked with the cam driving mechanism and can release the elastic clamping mechanism. The electricity verification part is adopted to perform an electricity verification operation; the electricity discharge part is adopted to perform an electricity discharge operation, so that the electricity verification and electricity discharge functions to electrical equipment are realized; the integrated apparatus is convenient to operate and high in working efficiency; the integrated apparatus is provided with three gears, a standby gear, an electricity verification gear and an electricity discharge gear; the electricity verification gear is arranged in front of the electricity discharge gear; meanwhile, the integrated apparatus is provided with an audible and visual alarm for reminding an operator so as to avoid a misoperation and to improve safety.

Description

technical field [0001] The invention relates to the field of electric inspection operation and discharge operation of high-voltage electrical equipment, in particular to an integrated device for inspection and discharge. Background technique [0002] When inspecting high-voltage electrical equipment, qualified contact electroscopes with corresponding voltage levels should be used to inspect the electricity of each phase separately at the place where the grounding wire is installed or the grounding switch is closed. Cables, capacitors and other large-capacitance equipment, after the power failure withdraws the applied working voltage, there is still a large amount of residual charge in the cable and capacitor, and the remaining charge of the equipment needs to be discharged repeatedly. When the remaining charge is exhausted, there will be a high voltage on the equipment. Once the staff touches this high voltage, it may cause personal electric shock. [0003] The tools for el...

Problems solved by technology

Cables, capacitors and other large-capacitance equipment, after the power failure withdraws the applied working voltage, there is still a large amount of residual charge in the cable and capacitor, and the remaining charge of the equipment needs to be discharged repeatedly. When the remaining charge is exhausted, there will be a high voltage on the equipment. Once the staff touches this high voltage, it may cause personal electric shock

[0003] The tools for electrical inspection and discharge operations are electroscope pens and discharge rods respectively. The electroscope pens or discharge rods currently on the market have single functions, and the work efficiency is low when used. In the process of work, it was found that some careless operators did not work. Discharge work is carried out after experiencing electricity, and serious safety accidents will occur if the equipment has voltage
