Description

Technical Field

[0002] High and low voltage distribution cabinets are extremely important distribution equipment in the power supply system, mainly used for power distribution, control, metering and connecting cables. However, in actual use, high and low voltage distribution cabinets often face some problems. In some humid environments, such as basements and places near water sources, moisture can easily enter the distribution cabinet. Long-term exposure to a humid environment will cause electrical components to become damp, affecting their normal operation and service life, and may even cause safety accidents such as short circuits and leakage. For example, in some areas in the south, during the rainy season, the air humidity is high, and the moisture-proof problem of the distribution cabinet is particularly prominent. The electrical components in the high and low voltage distribution cabinets will generate a lot of heat when working. If the heat cannot be dissipated in time, the temperature in the cabinet will rise. Excessive temperature will affect the performance and reliability of electrical components, reduce their working efficiency, and in severe cases, cause damage or burning of components. Especially when the load in the distribution cabinet is large, the heat dissipation problem is more severe. For example, in the distribution room of some large factories, due to the large number of equipment and high heat generation, heat dissipation has become a problem that must be solved.
