Description
Technical Field
[0001] The utility model relates to the technical field of power switch cabinets, in particular to a moisture-proof structure for a power switch cabinet. Background Art
[0002] The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many ways to classify switchgear. For example, according to the installation method of the circuit breaker, it can be divided into removable switchgear and fixed switchgear; or according to the different cabinet structures, it can be divided into open switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear; according to the different voltage levels, it can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switchgear, etc. It is mainly suitable for various occasions such as power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, etc.
[0003] At present, most switch cabinets have poor sealing performance because they are mostly sealed with sealing strips. However, the switch cabinets will inevitably open and close their doors frequently during use. Long-term use will cause the sealing strips to loosen or fall off, thereby reducing their sealing performance. In addition, the heat dissipation holes of most switch cabinets are open-type designs. If they are placed in areas with more rainy seasons or humid areas, humid gases may enter the switch cabinet through the heat dissipation holes, resulting in poor moisture-proof effect. Therefore, we urgently need a moisture-proof structure for power switch cabinets to solve the above problems. Utility Model Content
