Intelligent direct current circuit breaker cabinet convenient in placing direct current circuit breaker handcart

Abstract

The invention aims to provide an intelligent direct current circuit breaker cabinet convenient in placing a direct current circuit breaker handcart. A current circuit breaker handcart chamber is usedfor placing the current circuit breaker handcart, a guide rail is arranged to carry out feeding on the handcart, an approach rail guides fed materials, the handcart enters the circuit breaker handcartchamber, the approach rail can be collected to be convenient in sealing a cabinet body, and a metal sealing wiring channel performs a shielding function and also can prevent a cabinet arcing fault from damaging a control line. The cabinet body and an instrument room are independently provided with an insulation plate to avoid a situation that the cabinet body is electrified to generate dangers, the insulating installation screw of the cabinet body effectively avoids the influence of free metal ions on the cabinet body when the circuit breaker has faults to spray arc light, a water guiding plate on the top of the cabinet body conveniently enables water to flow to the ground behind the cabinet body when water drips in the outside, the safety of the cabinet body is protected, the whole cabinet is favorably matched with the direct current circuit breaker handcart, the handcart conveniently enters and leaves, and the cabinet body is good in sealing, is high in safety and convenient in operation.

Description

technical field [0001] The invention relates to the field of circuit breakers, in particular to an intelligent DC circuit breaker cabinet which is convenient for placing a DC circuit breaker handcart. Background technique [0002] At present, my country's urban rail transit system is powered by DC system. However, most of its DC power supplies are provided by high-power silicon rectifier devices. Due to the low overload capacity of silicon rectifier device components, the requirements for DC power grid protection components are higher. Quickly analyze the important components in the rail transit of the DC special circuit breaker. At present, a handcart has been developed. The intelligent DC circuit breaker is set on the handcart, and the handcart is pushed into the intelligent DC circuit breaker cabinet where the DC circuit breaker handcart is conveniently placed, and connected to the cabinet. However, the current cabinets cannot place handcarts well, it is troublesome to ...
