Power distribution cabinet

Abstract

The invention relates to the technical field of electrical equipment, and discloses a power distribution cabinet. The power distribution cabinet comprises a first cabinet body, an isolation transformer positioned in the first cabinet body, a plurality of branch modules which are electrically connected with the isolation transformer, output branch mutual-inductance modules which correspond to the branch modules and induce the output currents of the branch modules, and a monitoring module which is electrically connected with the output branch mutual-inductance modules, wherein the isolation transformer comprises at least one output connection terminal, and each output connection terminal can be electrically connected with the corresponding standby branch module; the monitoring module is provided with signal-wire adapter sockets corresponding to the output connection terminals, each signal-wire adapter socket can be electrically connected with the corresponding standby output branch mutual-inductance module, and each standby output branch mutual-inductance module induces the output current of the corresponding standby branch module. Because at least one output connection terminal is reserved on the isolation transformer, and is provided with corresponding signal-wire adapter sockets, capacity expanding of a power utilization system is convenient, and the cost of capacity expansion is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a distribution cabinet. Background technique [0002] In the communication equipment rooms of banking, telecommunications and mobile industries, it is necessary to perform power distribution, current loop protection and metering for important electrical equipment such as servers and networks. electric cabinet. [0003] The power distribution cabinet usually includes an isolation transformer electrically connected to the external input cable, and a plurality of branch circuit modules that are connected to the multiple branches separated from the output end of the isolation transformer in one-to-one correspondence. The electrical connection of electrical equipment, the output cable jacket of each branch circuit module is equipped with a transformer, each transformer is connected to the monitoring module through a signal line, and the monitoring module is used to compr...

AI Technical Summary

Problems solved by technology

After the power supply equipment products are put into operation, a larger-scale power distribution cabinet needs to be configured in the later expansion, resulting in the inability to expand or the difficulty of expansion in the later period, and the cost of expansion and transformation is also high
