Special handcart switch circuit electrical inspection device for 35KV switch cabinet

Abstract

The embodiment of the invention provides a special handcart switch circuit electrical inspection device for a 35KV switch cabinet, comprising a rear handcart switch cabinet door, an electrical inspection door, a lock, an electromagnetic lock, a lock blade and an electrical displayer, wherein the electromagnetic lock and the electrical inspection door are arranged on the rear handcart switch cabinet door; the lock is arranged on the electrical inspection door; the lock blade is interlocked with the electromagnetic lock; the electromagnetic lock can be electrified only when a normally-closed contact of the handcart travel switch and a normally-closed contact of a relay controlled by the electrical displayer are closed simultaneously. The special handcart switch circuit electrical inspection device for the 35KV switch cabinet has a simple structure, can be operated simply and conveniently, has reliable performance, can reduce the operation of an electrical transformation operator, and ensures to achieve the requirement of safe and reliable power supply during the power supply running process.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an electrical inspection device for handcart switch lines specially used for 35KV switch cabinets. Background technique [0002] In the operation of the power system, ensuring the safe and reliable operation of the substation is one of the first and most important requirements. A large number of operations in the substation operation are prone to misoperation and increase the incidence of accidents. In order to reduce or avoid the occurrence of misoperation, it is necessary to reduce the amount of operation of the substation operation staff. [0003] To reduce the amount of personnel operations while ensuring the safe operation of the equipment, it is necessary to first improve the reliability and rationality of the power equipment. At present, in the inspection process of the 35KV busbar and line of the indoor complete set of equipment, it is necessary to pu...

AI Technical Summary

Problems solved by technology

At present, in the inspection process of the 35KV busbar and line of the indoor complete set of equipment, it is necessary to push the switch of the handcart out of the cabinet from the test position, then push the handcart into the cabinet, and then shake the handcart from the test position to the working position, and then conduct an electrical test, which greatly increases the operation of the operator and prolongs the operation time
