Abstract

The invention discloses a cabinet door interlocking device for a fully insulated ring network cabinet. Lock mounting plate, electromagnetic lock baffle, electromagnetic locking module, the electromagnetic locking module is installed on the electromagnetic lock mounting plate, and fixed by the electromagnetic lock baffle; the electromagnetic locking module is composed of charged display, electrical circuit and electromagnetic Composed of lock connecting rods, when the cable room of the PT cabinet is electrified, the contact of the charged display will act, and the electromagnet will be in the de-energized state through the electrical circuit, the electromagnet connecting rod will not act, and the cabinet door cannot be opened. When the high-voltage cable room is de-energized , the charged display contact moves, the electrical circuit is energized, and the electromagnetic lock linkage moves to unlock.

Description

technical field [0001] The invention belongs to power distribution equipment, in particular to an interlocking device for a fully insulated ring network cabinet door. 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, on the premise of ensuring product quality, realize by The transformation of low-reliability mechanical interlocks into stable and reliable electromechanical interlocks has become a very urgent issue....
