Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a high-voltage complete switch cabinet with moisture-proof function. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switch cabinets, with high-voltage busbars, such as power plants, etc. Some are also equipped with low-frequency load shedding to protect the main equipment.

[0003] The switch cabinets currently available on the market are basically installed in basement distribution rooms with heavy humidity. Moisture corrosion can cause failure of the control and protection circuits, thereby causing damage to product functions, so moisture-proof and dehumidification functions are very important.

[0004] For example, Chinese patent CN214478694U discloses an indoor high-voltage complete switchgear with efficient moisture-proof and dehumidification functions. The three sets of cabinets are basically installed in the basement power distribution room with heavy humidity. Long-term use may cause moisture to enter the interior of the device, causing the product to rust or even damage the equipment. Moisture corrosion may cause the control protection circuit to fail. Therefore, a heater may be installed on the heater bracket. The heater can clear the moisture in the device to prevent the product from rusting. Moisture corrosion may cause the control protection circuit to fail, and moisture erosion of the primary system circuit may cause damage to the product function.

[0005] However, the device uses a heater to remove moisture inside the device, which will increase the temperature of the high-voltage switchgear and cause overheating of circuit components inside the switchgear, affecting the normal use of the switchgear.

[0006] For this reason, we urgently need to provide a high-voltage complete switch cabinet with moisture-proof function. Utility Model Content
