Abstract

The invention discloses a power distribution cabinet and is designed aiming to solve the problems that a rear seal plate of a conventional power distribution cabinet cannot be locked electrically and the like. The power distribution cabinet comprises a cabinet body and a rear seal plate arranged on the cabinet body, wherein an electromagnetic lock is arranged on the inner side of the upper part of the rear seal plate; a lock plate is arranged in a position, close to the electromagnetic lock, in the inner side of the rear seal plate; a lock bolt hole is formed in the lock plate; a lock bolt of the electromagnetic lock can penetrate through the lock bolt hole; at least one insertion plate is fixedly arranged at the lower part of the inner side of the rear seal plate; at least one insertion hole is formed in the position, corresponding to the at least one insertion plate, in the cabinet body; and part of the insertion plates are inserted into the insertion holes. The power distribution cabinet is simple and reliable in structure, the rear seal plate can be electrically locked, and the use is safer.

Description

technical field [0001] The invention relates to a power distribution cabinet. Background technique [0002] The existing rear sealing plate of the power distribution cabinet can meet the mandatory standard of five-proof lockout, that is, to prevent the disconnector from opening and closing with load (the disconnector cannot be operated when the circuit breaker, load switch and contactor are closed); , Mis-closing circuit breakers, load switches, and contactors (only when the operating instructions correspond to the operating equipment can the operated equipment be operated); prevent the circuit breaker and load switch from being closed when the grounding switch is in the closed position (only when the grounding switch is in the open state) , to close the isolating switch or handcart to enter the working position, and operate the circuit breaker and load sharing switch to close); prevent the grounding switch from being mistakenly closed when electrified (only when the circuit...
