Problems solved by technology
[0004] The above-mentioned dehumidifiers for power cabinets and those in the prior art generally install heaters and blowers on the power cabinet to ensure that the air in the cabinet is dry. Although the humidity in the cabinet is reduced like this, the temperature in the cabinet will increase, which is harmful to the inside of the cabinet. The reliability and service life of the instruments, components, wires, and plastic parts are greatly affected, and the existing dehumidification device does not have other capabilities, which affects the practicability of the power cabinet. Therefore, it is urgent to design a power cabinet dehumidification device solve the above problems

The invention discloses an electric power cabinet dehumidification device, and relates to the technical field of electric power cabinets. The device comprises a power cabinet body, two second supports are installed on the outer wall, close to the bottom, of one side of the power cabinet body through bolts, a drying tank is welded into the two second supports, a connecting pipe is welded to one end of the drying tank, and the end, away from the drying tank, of the connecting pipe is in threaded connection with an air inlet assembly. A gas conveying pipe extending into the power cabinet body is inserted into one end of the gas inlet assembly, a mounting pipe is mounted at the center of the outer wall of the top of the power cabinet body through bolts, and an electromagnetic valve is in threaded connection with the outer wall of one side of the mounting pipe through a pipeline. When the control box detects that moisture in the electric power cabinet body is heavy, the control box controls the exhaust assembly and the air inlet assembly to be started at the same time, so that air in the electric power cabinet body is pumped out of the electric power cabinet body, and the air subjected to moisture absorption treatment by the drying tank enters the electric power cabinet body; damage to electronic devices in the power cabinet body caused by heating and drying in an original mode is reduced.
Description
technical field [0001] The invention relates to the technical field of power cabinets, in particular to a dehumidification device for power cabinets. Background technique [0002] The power cabinet is an important facility in the power system, and its safe operation is related to the normal operation of various related equipment, so its protection and inspection are also highly valued. If the power cabinet operates in a humid environment, it will bring hidden dangers to its safety. When the temperature is above 30°C and the relative air humidity is above 80%, condensation will occur, which will cause the terminals of power equipment to corrode and reduce Short circuit caused by insulation performance, resulting in undue power failure and loss. [0003] For example, a power cabinet dehumidification device with an authorization announcement number of CN106451143A and an authorization announcement date of 20180410 includes a switchgear cabinet and a base disposed under the cab...
