0.4KV-based power failure-free operation device and method

Abstract

The invention relates to the technical field of electric maintenance equipment, and provides a 0.4KV-based power failure-free operation device and method. The 0.4KV-based power failure-free operationdevice comprises an insulating total-shielding tool and a set of operation tool, wherein the insulating total-shielding tool is used for shielding a switch part of a switch cabinet, a feeder line below the switch and to-be-shielded parts in metal grounding bodies on four walls of the switch cabinet; and the set of operation tool is used for fastening a nut at the rear side of the switch and controlling the switch to be replaced after the shielding of the insulating total-shielding tool is finished, so as to realize the insulating total shielding of contactable electrified parts and grounding parts in the switch cabinet by a single person, ensure that the operators do not suffer accidents of mistakenly contacting the electrified bodies when carrying out power failure-free operation, avoid single-phase grounding and inter-phase short circuit accidents, ensure that enough safety distances are kept between the operators and the electrified bodies, enhance the safety of the low-voltage power failure-free operation and ensure the safe and reliable development of the operation.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a 0.4 kV non-stop operation device and a non-stop operation method. Background technique [0002] With the rapid development of my country's national economy and the rapid improvement of people's living standards, people's demand for electricity is increasing, and enterprises and residents have put forward higher requirements for the reliability, quality and safety of power supply. With the emergence and development of low-voltage non-stop operation, 0.4 kV distribution network non-stop operation has made great progress. [0003] At present, the 0.4 kV non-stop power operation is in the pilot stage, and there is no formed shielding tool and perfect operation process. At present, operations such as replacing the circuit breaker of the 0.4 kV switchgear, tightening the outlet terminals of the circuit breaker, and eliminating defects in the switchgear a...

AI Technical Summary

Problems solved by technology

[0005] Specifically, the technical problem to be solved by the present invention is to provide a 0.4 kV non-stop operation device, aiming to solve the problem of replacing the 0.4 kV switch cabinet circuit breaker, fastening the circuit breaker outlet terminals and switches in the prior art. Operations such as cabinet elimination are mostly carried out through power outage maintenance, which leads to a decrease in customer satisfaction, and also affects the economic and social benefits of power supply companies.
