Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a temperature regulating function. Background Art

[0002] A distribution cabinet is an electrical device mainly used for power distribution and power control in power systems. It is a low-voltage distribution cabinet that is assembled with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen. In normal operation, the distribution cabinet can connect or disconnect the circuit through manual or automatic switches. In high temperature environments and under heavy loads, the internal temperature of the distribution cabinet is prone to rise, which will not only reduce the service life of the equipment, but also cause potential safety hazards. Therefore, measures need to be taken to adjust the temperature to ensure the normal operation and safety of the distribution cabinet.

[0003] Common distribution cabinets are usually composed of structures including cabinets, protective ground groups, main circuit fuse groups, branch circuit breaker groups, etc. Open the door of the distribution cabinet, connect the electrical components with cables, etc., and provide overload protection through circuit breakers, contactors, leakage protectors and other equipment, and then close the door of the distribution cabinet. This is a common distribution cabinet structure and usage method. When the electrical components of a traditional distribution cabinet work for a long time, a certain amount of heat will be generated, which will increase the temperature inside the distribution cabinet. When the temperature inside the distribution cabinet reaches a certain level, the electrical components will be damaged due to excessive temperature. Some distribution cabinets heat the cabinet body by adding a cooling fan to the cabinet body to regulate the temperature inside the cabinet. However, in this way, when the outside world is under low temperature conditions, the temperature inside the cabinet body cannot be raised in time, resulting in the inability to adjust the temperature inside the cabinet body according to different situations, causing the electrical components to be corroded and damaged in low temperature environments. For this reason, a distribution cabinet with temperature regulation function is proposed. Utility Model Content
