Abstract

The utility model discloses a switch cabinet anti-condensation and dehumidifying device comprising a shell. The dehumidifying device comprises a sensor which is installed in a switch cabinet. The sensor is electrically connected with a relay in the shell. A power supply supplies power to the dehumidifying device via the relay. The dehumidifying device also comprises an air pipe. The two ends of the air pipe stretch out of the shell, wherein one end is provided with an air inlet fan, and the other end is provided with an air outlet fan. The air inlet fan and the air outlet fan are installed on corresponding holes of the switch cabinet. One segment of the air pipe penetrates through a condensation chamber. Condensed water is discharged via a drainpipe connected with the air pipe after being refrigerated by semiconductor refrigeration sheets which are installed in the condensation chamber. According to the disclosed dehumidifying device, air in the switch cabinet is enabled to flow in a cycle way via the air pipe through triggering if the sensor detects that humidity in the switch cabinet surpasses the preset value. Condensation and dehumidifying are performed in the process so that the effect of reducing air humidity in the switch cabinet is achieved.
