Temperature control monitoring device for fan for assisting in heat dissipation of high-voltage distribution cabinet

Abstract

The invention discloses a temperature control monitoring device for a fan for assisting in heat dissipation of a high-voltage distribution cabinet. The device comprises a first air switch, a second air switch, a temperature controller, a time relay, an intermediate relay, an indicating lamp, a micro switch and the fan; the fan is connected with the time relay and the temperature controller; the temperature controller is connected with the first air switch and the second air switch; the micro switch is arranged on one side of the fan; one end of the micro switch is connected to the first air switch; the other end of the micro switch is connected to the second air switch through the indicating lamp; the micro switch is further connected with the intermediate relay through the time relay; theintermediate relay is connected to the second air switch; and the intermediate relay is connected with an alarm system. Temperatures in the high-voltage distribution cabinet are acquired through sensors in real time, and operation conditions of the fan for assisting in heat dissipation are monitored through the switches and the relays, so that the accident generation frequency is reduced, and real-time remote monitoring of the temperatures in the high-voltage distribution cabinet and the fan is realized.
