Anti-misoperation locking device between box-type transformer substation low-voltage side power supply and power generation vehicle access power supply

Abstract

The invention discloses an anti-misoperation locking device between a box-type transformer substation low-voltage side power supply and a power generation vehicle access power supply. The anti-misoperation locking device comprises a low-voltage chamber lock installed in a box-type transformer substation low-voltage cabinet, an interlocking piece installed on an isolation switch connecting rod anda power generation vehicle access chamber lock installed on a door plate of a box-type transformer substation power generation vehicle access chamber. The low-voltage chamber lock is matched with theinterlocking piece to lock and unlock the isolation switch connecting rod, and the power generation vehicle access chamber lock locks and unlocks the door plate of the box-type substation power generation vehicle access chamber; and the low-voltage chamber lock and the power generation vehicle access chamber lock share one key. By the adoption of the technical scheme of 'two locks and one key' misoperation prevention locking, safety accidents caused by misoperation are avoided.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an anti-misoperation locking device between a low-voltage side power supply of a box-type transformer and a power supply connected to a power generation vehicle. Background technique [0002] With the rapid development of my country's economy, power supply has become the basic demand of the society. In the past ten years, due to the widespread development of urban network reconstruction projects in various parts of the country, a large number of pre-installed box-type substations (referred to as: box-type substations) have appeared in industrial and mining enterprises. , beside municipal roads and in communities. During the operation of the box transformer, various reasons may cause the box transformer to lose power. However, some important industrial and mining enterprises and residential communities do not allow long-term power outages. At this time, emergency generator cars a...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an anti-misoperation locking device between the low-voltage side power supply of the box-type substation and the access power supply of the generator car to solve the problem of the access side power supply of the box-type substation. Only one of the two power supplies on the transformer side of the box-type transformer can be used to ensure the uniqueness of the power supply
