Problems solved by technology

[0003] Place a certain amount of desiccant in the switch cabinet to absorb water vapor in the air. This method can have a certain dehumidification effect, but the effect is very small. For the case of high indoor water vapor concentration, the desiccant will absorb water vapor after a long time. If the drying effect is too high, or the design of improving the overall protection level of the switch cabinet is adopted to prevent foreign objects from entering the cabinet, the humidity in the switch cabinet can be reduced. However, if the switch cabinet is completely sealed, it will cause electronic damage in the switch cabinet. The heat emitted by the components cannot be discharged, which will affect the use of electronic components, and in severe cases will damage the electronic components

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a high and low voltage switch cabinet with heat dissipation and dehumidification functions. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. [0003] Place a certain amount of desiccant in the switch cabinet to absorb water vapor in the air. This method can have a certain dehumidification effect, but the effect is very small. For the case of high indoor water vapor concentration, the desiccant will absorb water vapor after a long time. If the drying effect is too high, or the design of improving the overall protec...
