Characteristics of Intelligent Temperature and Humidity Controller

Temperature and humidity controllers are mainly used for regulating and controlling the internal temperature and humidity of equipment such as medium and high voltage switchgear, terminal boxes, ring main units, and box type substations. They can effectively prevent equipment failures caused by low and high temperatures, as well as creepage and flashover accidents caused by moisture or condensation. The products are divided into: ordinary type and intelligent type.

The temperature and humidity controller mainly consists of three parts: sensors, controllers, and heaters (or fans, etc.).

Sensors detect temperature and humidity information inside the cabinet and transmit it to the controller for analysis and processing. When the temperature and humidity inside the cabinet reach or exceed the pre-set values, the relay contacts in the controller close, and the heater (or fan) is powered on to start working, heating or blowing air inside the cabinet; After a period of time, the temperature and humidity inside the box move away from the set values, the relay contacts in the controller disconnect, and heating or blowing stops. In addition to its basic functions, the intelligent model also comes with additional features such as disconnection alarm output, communication, and forced heating and blowing.
