Abstract

The invention provides a power distribution cabinet. The power distribution cabinet comprises a first fuse protector, a current transformer for metering, an inlet breaker, a current transformer for measurement and an outlet breaker, wherein the first fuse protector, the current transformer for metering, the inlet breaker, the current transformer for measurement and the outlet breaker are connected sequentially; the inlet breaker comprises a first breaker and a second breaker which are arranged in parallel, and a power saver is serially connected between the second breaker and the current transformer for measurement; the outlet breaker comprises a third breaker, a fourth breaker and a fifth breaker which are arranged in parallel; and the inlet breaker comprises a breaker body, a controller and a communication module, wherein the controller is used for receiving an external control signal and transmitting the control signal to control the breaker body to be switched on or off through a communication module. Through the power distribution cabinet, a user is not needed to switch off or on the breakers through manual operation, so that operation can be simplified and safety can be improved; and the current transformer for metering is utilized to realize a metering function simultaneously.

Description

technical field [0001] The utility model belongs to the technical field of power distribution cabinets, in particular to an intelligent power distribution cabinet with power-saving functions. Background technique [0002] At present, the incoming switch of the power distribution cabinet used in the market is basically a manual operation of a knife fuse switch or a molded case circuit breaker. It is laborious and inconvenient to open and close the switch, and the manual operation method is also unsafe. [0003] Moreover, the existing power distribution cabinet is only used for power distribution and has a single function. Contents of the invention [0004] In view of this, the purpose of the utility model is to provide a distribution cabinet to solve the above problems. [0005] In order to achieve the above purpose, an embodiment of the utility model provides a power distribution cabinet, which includes a first fuse, a current transformer for measurement, a circuit breake...
