Description

TECHNICAL FIELD

[0001] The present application belongs to the field of transformer control cabinet equipment, and particularly relates to a transformer control cabinet. BACKGROUND

[0002] A large amount of heat is generated in the operation of a transformer, and the increase of heat will increase the temperature in the existing transformer control cabinet, thereby causing serious damage to the electrical elements arranged in the transformer control cabinet. Therefore, the existing transformer control cabinet is usually provided with a cooling system for cooling. By starting the cooling fan to blow air into the inside of the cabinet shell, the induced draft fan is started to operate, so that the hot air in the inside of the control cabinet is discharged, the blowing of the cooling fan and the exhaust of the induced draft fan form a circulating convection in the inside of the control cabinet, and the heat dissipation efficiency in the inside of the control cabinet is accelerated.

[0003] In the existing cooling system, in order to avoid the water and dust from the outside entering the inside of the control cabinet and polluting the circuit in the inside of the control cabinet, a filter device is usually installed at the air inlet of the transformer control cabinet.

[0004] The filter element in the air inlet filter device of the existing transformer control cabinet is usually fixedly arranged, and the filter element needs to be replaced after a long time of filtration. The existing filter element replacement usually stops the filtration of the filter element of the filter device, so that the gas with impurities enters the cabinet body. This replacement method has the problem that the water and dust from the outside enter the inside of the control cabinet, thereby polluting the circuit or the electrical elements and causing accidents.
