Abstract

The invention discloses a 10KV two-station ring main unit door interlocking device which comprises an incoming cabinet main body. The device is characterized in that a door interlocking device is assembled on the incoming cabinet main body, and consists of an electromagnetic lock mounting plate, an electromagnetic lock baffle plate and an electromagnetic lock, wherein the electromagnetic lock is arranged on the electromagnetic lock mounting plate, and is fixed by the electromagnetic lock baffle plate. According to the device, an electromagnetic locking module is arranged on a door after the non-standard design of a shell, a contact of a live display acts when a high-voltage cabinet cable chamber is energized, an electromagnet is de-energized by virtue of an electric loop, an electromagnetic lock connecting rod does not act, and the door cannot be opened; when the high-voltage cable chamber is in a de-energized state, the contact of the live display acts, the electromagnetic loop is energized, and the electromagnetic lock connecting rod acts to realize unlocking, so that the door can be opened, an operator can safely enter a live gap, and the requirements of five prevention, remote operation and distribution network automation can be met.

Description

technical field [0001] The invention belongs to power distribution equipment, in particular to a door interlocking device of a 10KV two-station ring network cabinet. Background technique [0002] With the further acceleration of the conventional distribution network to the intelligent distribution network required by the State Grid, the intelligent control of distribution network products and the solution of remote operation problems have experienced several years of rapid development in recent years. The implementation part puts forward multiple requirements, complete functional nodes, stable operation, simple and reliable structure, etc., in order to actively promote and respond to the requirements of the State Grid, so as to realize the above functions on existing products, and realize the remote control under the premise of ensuring product quality. Control becomes a very pressing issue. [0003] A cabinet door interlocking device of a ring network cabinet is disclosed ...
