Problems solved by technology

[0002] The power distribution cabinet is a commonly used equipment in the power transmission of the grid. The current distribution cabinet is mainly composed of a box body and a built-in circuit breaker. The existing circuit breaker is directly connected to the wire. On the one hand, it is inconvenient to disassemble, and on the other hand, the safety is poor; At the same time, the molded case circuit breakers are connected side by side, which is prone to arc short circuit when the large current is disconnected. The safety performance is poor and the use is unsafe.

Abstract

The invention provides a power distribution cabinet. The power distribution cabinet comprises a cabinet body and a molded case circuit breaker, wherein the molded case circuit breaker is arranged in the cabinet body. The power distribution cabinet further comprises copper bars, a wire inlet knife switch and inter-phase separator pieces, wherein the cooper bars are connected with the wire inlet knife switch, the inter-phase separator pieces are arranged on the molded case circuit breaker, the molded case circuit breaker is connected with the copper bars through wires, and the copper bars, the wire inlet knife switch and the inter-phase separator pieces are placed inside the cabinet body. The power distribution cabinet has the advantages of facilitating maintenance and dismounting, preventing arc-light short circuits caused by disconnection due to heavy currents and improving the safety performance.

Description

technical field [0001] The invention belongs to the field of power distribution equipment, in particular to a power distribution cabinet. Background technique [0002] The power distribution cabinet is a commonly used equipment in the power transmission of the power grid. The current distribution cabinet is mainly composed of a box body and a circuit breaker built in it. The existing circuit breaker is directly connected to the wire. On the one hand, it is inconvenient to disassemble and on the other hand, the safety is poor; At the same time, the molded case circuit breakers are connected side by side, which is prone to arc short circuit when the large current is disconnected. The safety performance is poor and the use is unsafe. Contents of the invention [0003] The problem to be solved by the present invention is to provide a power distribution cabinet, which is especially suitable for reducing potential safety hazards and is convenient for disassembly and maintenance....
