Problems solved by technology
[0003] Electric control cabinets in humid areas are often prone to damp, and the electric control cabinets after being damp are prone to short circuit. Therefore, the existing electric control cabinets use the hot air generated by the heat pump to dry the humid air in the cabinet to solve the problem of damp in the electric control cabinets. However, the existing electrical control devices that use heat pumps to dry often lead to the inside of the cabinet when the air in the heat pump is not fully heated, which easily increases the amount of humid air in the cabinet and aggravates the problem of moisture in the cabinet

The electrical control device comprises a cabinet body, a heat pump body is fixedly connected to the inner bottom wall of the cabinet body, a plurality of air outlets are formed in the side walls of the two sides of the cabinet body, and a ventilation plate located above the heat pump body is jointly and fixedly connected between the inner walls of the two sides of the cabinet body; a ventilation plate is arranged on the upper side wall of the heat pump body, a plurality of ventilation holes are formed in the upper side wall of the ventilation plate, air inlets are jointly formed in the joints of the two side walls of the heat pump body and the cabinet body, a blast pipe is fixedly connected to the inner top wall of the heat pump body, and sealing mechanisms are arranged on the two side walls of the blast pipe. After the expansion air bag is heated and expanded, hot air generated by the heat pump body can be automatically introduced into the cabinet body, air in the cabinet body is dried, and the problems that when air in the heat pump is not completely heated, the air is introduced into the cabinet body, the amount of humid air in the cabinet body is likely to be increased, and the cabinet body is affected with damp are solved.
Description
technical field [0001] The present invention relates to the technical field of drying of electrical control devices, in particular to an electrical control device using heat pump drying. Background technique [0002] The electrical control cabinet is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements. Safety control cabinets for people and surrounding equipment, including power distribution cabinets, power distribution boxes and electrical control cabinets, etc., the circuit can be turned on or off with the help of manual or automatic switches during normal operation, and the circuit can be cut off with the help of protective appliances during faulty or abnormal operation Or alarm, the measuring instrument can display various parameters in operation, and can also adjust some electrical parameters to prompt or send signals for dev...
