Problems solved by technology

[0003] There are many electronic components in the commonly used low-voltage power cabinets, which are prone to heat during work. Therefore, low-voltage power cabinets often need to have better heat dissipation capabilities. The heat dissipation effect of low-voltage power cabinets in the prior art is poor.

Abstract

The invention relates to the technical field of electric power, in particular to a low-voltage electric cabinet. The low-voltage electric cabinet comprises a cabinet body, a front cabinet door mechanism, a movable installation plate mechanism, steering wheel mechanisms, linkage opening and closing mechanisms, a rear cabinet door mechanism, a transmission wheel mechanism, a side cabinet door mechanism, a water cooling mechanism and an air cooling mechanism. The front end of the cabinet body is fixedly connected with the front cabinet door mechanism. The upper end of the movable installation plate mechanism is connected to the middle end inside the cabinet body, and the lower end of the movable installation plate mechanism is connected to the bottom surface inside the cabinet body. Each of the left and right ends of the movable installation plate mechanism is in meshed transmission connection with one steering wheel mechanism. Each of the two steering wheel mechanisms is in meshed transmission connection with one linkage opening and closing mechanism. The middle ends of the two linkage opening and closing mechanisms are respectively connected to the left and right ends of the rear end face of the cabinet body through sliding fit. The low-voltage electric cabinet is internally equipped with the water cooling mechanism and the air cooling mechanism, so that the heat of the electronic components inside the low-voltage power cabinet can be radiated, and a better heat dissipation effect and higher heat dissipation efficiency are achieved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a low-voltage power cabinet. Background technique [0002] Low-voltage power cabinets are the assembly of switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The measuring instrument can display various parameters during operation, and can also adjust some electrical parameters to prompt or send signals for deviations from the normal working state. [0003] There are many electronic components in the commonly used low-voltage power cabinets, which are easy to generate heat during operation. Therefore, the low-voltage power cabinets often need to have better heat dissipation capacity, and the low-voltage power cabinets in the prior art have poor...
