DC power cabinet

Abstract

The invention discloses a direct-current power cabinet in order to solve the problem in the prior art that the temporary direct-current power cabinet is large and heavy and inconvenient to carry, the internal structure and wiring are complex, assembly and debugging are time-consuming, the failure rate is high, and replacement of the direct-current system takes a long time. According to the direct-current power cabinet, four rollers are mounted a the four corners of the outer side of the bottom of a rectangular cabinet body, the two sides of the cabinet body are each equipped with a cabinet door, push-and-pull handles are mounted on the outer side of each cabinet door, each direct-current output unit is connected in parallel to one side of a direct-current outgoing circuit breaker, the other side of the direct-current outgoing circuit breaker is connected with the output ends of two direct-current chargers which are main and standby direct-current chargers relative to each other, the alternating-current input ends of the two direct-current chargers are respectively controlled by corresponding direct-current charger alternating-current incoming circuit breakers, the other ends of the two direct-current charger alternating-current incoming circuit breakers away from the direct-current chargers are connected with an alternating-current main incoming circuit breaker, and the alternating-current main incoming circuit breaker directly outputs multiple alternating-current output units. By using the scheme, the efficiency of direct-current system replacement is improved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a DC power supply cabinet. Background technique [0002] The DC system is used in power plants, various substations and other users who use DC equipment to provide DC power for signal equipment, protection, automatic devices, emergency lighting, emergency power and circuit breaker opening and closing operations. [0003] The reliability of the DC system plays a vital role in the safe operation of the substation. It is the guarantee for the safe operation of the substation and an important part of the substation. The DC system must be highly valued. The daily inspection and testing of the DC system must be And maintenance work is placed in an important position, and when various accidents occur, priority is given to restoring the power supply of the DC system. [0004] The replacement of the DC system without power failure is difficult, the process is complicated, and the safety...
