Description

Technical Field

[0002] With the progress of society, JP cabinets have been widely used. JP cabinets (new intelligent distribution area integrated distribution box) are a new integrated control box that integrates power distribution, protection, control, and reactive compensation. It is used in substations, factories, industrial and mining enterprises, large power plants, petroleum, chemical enterprises, large steel mills, high-rise building power centers, reactive compensation, metering, power distribution and other occasions. When circuit components work at the same time for a long time, a lot of heat will be generated. The heat will be retained in the JP cabinet body for a long time and difficult to dissipate. In the hot summer, the heat will be more serious, and then ventilation and heat dissipation will be carried out. The ventilation structure is generally composed of ventilation holes and fans, and generally does not have moisture-proof function. After humid air enters the interior of the JP cabinet, it is easy to cause the circuit components to be damp and short-circuited, affecting the safety of the JP cabinet when in use. There are also desiccant for moisture-proof. Generally, a mesh shell structure is used to place the desiccant, and the opening is generally facing upwards, which is convenient for the placement of the desiccant, but the bulk desiccant is difficult to take out, which affects the convenience.
