The novel measuring cabinet is reasonable in design, convenient to operate and maintain, high in practicability and high in level of protection, and the remote management can be further realized.

Description

[0001] Technical field: [0002] The invention relates to the technical field of electric appliances, in particular to a novel metering cabinet. [0003] Background technique: [0004] The electric energy metering cabinet is the most important electric energy metering equipment. The metering cabinet is widely used in power supply and distribution systems with AC 50Hz, single-phase 240V, three-phase 450V or less, and total current of 400A or less in industrial and mining enterprises, institutions, high-rise buildings in residential quarters and public facilities. , as the power distribution, control, measurement and safety protection of electrical equipment for power distribution terminal equipment. [0005] In the prior art, the low-voltage metering cabinet is mainly used to measure electricity. The metering cabinet mainly includes a cabinet body, which is provided with a door. The door is usually hinged on one side of the cabinet body, and the hinge between the door and the ca...

Problems solved by technology

[0005] In the prior art, the low-voltage metering cabinet is mainly used to measure electricity. The metering cabinet mainly includes a cabinet body, which is provided with a door. The door is usually hinged on one side of the cabinet body, and the hinge between the door and the cabinet body is exposed outside the cabinet body. It is easy to be stolen by people who dismantle the hinges between them and the cabinet and open them to steal electricity. In addition, some people will use small long tools to insert into the cabinet from the gap between the door and the door frame of the cabinet to steal electricity. The metering cabinet of this design has a low level of protection against electricity theft by users. These stealing behaviors have seriously affected the normal use of the metering cabinet and caused serious property losses to the power supply company.
