Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of low-voltage cabinet heat dissipation, in particular to a low-voltage cabinet heat dissipation top cover. Background Art
[0002] A low-voltage cabinet is an electrical equipment whose main function is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. There are many ways to classify switch cabinets. For example, they can be divided into withdrawable low-voltage cabinets and fixed low-voltage cabinets according to the installation method of circuit breaker. Low-voltage cabinets are suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries for transmission, distribution and energy conversion. Therefore, many switchgear for distribution and transmission will be installed inside the low-voltage cabinet, and it is used in many places with complex environments.
[0003] The cooling device of the low-voltage cabinet is usually set on both sides, and is equipped with fans and air conditioners inside. The top does not have a heat dissipation effect. When the cooling devices such as fans and air conditioners are not started, the heat dissipation performance is poor. Since the equipment components inside the low-voltage cabinet are in a high-temperature environment for a long time, the service life of the equipment components will be reduced, resulting in equipment failure, electrical fires and other safety hazards. In addition, most of the existing low-voltage cabinet heat dissipation top covers use single-layer heat dissipation holes. However, this design cannot play a good dust-proof role. After the equipment components are covered with dust, they absorb moisture in the air, which will corrode some exposed equipment components. Over time, it may cause insulation reduction, short circuit, grounding and other accidents. Utility Model Content
