Lightning arrester discharge counter live replacement device and using method for the same

Abstract

The invention discloses a lightning arrester discharge counter live replacement device and a using method for the same. The lightning arrester discharge counter live replacement device comprises insulation operation rods, insulation rotation screws, copper line clamp lower surfaces, copper line clamp adjustment surfaces, copper line clamp upper surfaces, copper line clamp adjustment surface upgoing guide grooves, a short circuit line, copper connection noses, short circuit line fixing bolts, insulation top caps, insulation inner threads and screw thread fixing pins. The lightning arrester discharge counter live replacement device and the using method for the same eliminate long time waiting for an approval process for cutting (recovering) power and safety hazards in processes of cutting (recovering) power and arranging safety measures by personnel. The lightning arrester discharge counter live replacement device is small in size, easy in operation and easy to carry, and greatly shortens effective time of working, greatly reduces number of personnel participating in work, timely eliminates flaws in the discharge counter, recovers effective monitoring on the lightening arrester, and creates a condition for safety operation of a power grid. The replacement without power cutting improves reliability of supplying power and the power sale quantity, and creates economic benefits.

Description

technical field [0001] The invention relates to a live replacement device for a lightning arrester discharge counter and a use method thereof, belonging to the technical field of live replacement devices. Background technique [0002] At present, the staff of the power supply department adopts the method of power failure of the incoming power supply and lightning arrester to replace or deal with the fault discharge counter. However, due to the power outage work, it is necessary to report the power outage application plan first. After the power outage plan is approved, the power outage plan will be submitted electronically for approval by multiple departments. The work of replacing the fault discharge counter can be carried out. Such approval procedures are cumbersome and take a long time, which is expected to take about 15 working days. After the power supply line and lightning arrester are powered off, the safety measures to be arranged are highly demanding. When the opera...

AI Technical Summary

Problems solved by technology

Such approval procedures are cumbersome and take a long time, which is expected to take about 15 working days. After the power supply line and lightning arrester are powered off, the safety measures to be arranged are highly demanding. When the operator stops (returns) the power and arranges safety measures, there are unpredictable There are many hidden dangers to personal safety, and there are many departments and personnel involved (such as dispatching, substation operation, and substation maintenance personnel). In addition, the effective external power supply time and electricity sales are reduced due to power outages, which reduces the reliability of power supply for power consumers. At the same time, it also increases the economic operation cost of the power supply enterprise, and the economic benefit of the enterprise is damaged

In addition, for the arrester discharge counter of 110kV and above important lines, and the arrester discharge counter fault power outage processing involving the large-capacity main transformer part, due to the large impact of the power outage, the application for power outage often cannot be approved by the superior department in time, resulting in the failure of the fault discharge counter. The long-term operation in the state makes the discharge counter unable to effectively monitor the operation status of the arrester in real time. If the arrester fails at this time, the primary electrical equipment protected by the arrester may be threatened and damaged by lightning overvoltage or operating overvoltage.
