Humidity and Temperature Controller for High Voltage Switchgear Cabinet



SD-W200  Temperature and Humidity Controller

    The device mainly work in the humid environment or when steam generated.It is mainly used in the electrical equipment(such as outdoor terminal box, high and low voltage control cabinet, withdrawable switchgear, ring network switchgear, underground substation, substation, etc.) and other occasions of automated get rid of damp needed, anti-condense and temperature control.The device can be long-time used in a strong electric field, magnetic field and a variety of harsh natural environment.It can effectively prevent various accidents caused by humidity and condensing,ensuring efficient and safe operation in automatic operation.

 Main function 

1.Temperature logic control

The instrument measure the temperature of the environment at actual time, when the temperature of the environment is lower than 50degrees Celsius, the instrument automatically fire the heater to heat, once the temperature of the environment rise to 150degrees Celsius, the instrument automatically stop heat.

2.Condensation logic control

The instrument measure the humidity of the environment at actual time, when the environment humidity is higher than 85%RH condensation start control spot, the instrument will automatically fire heater to get rid of environment dampness, to avoid condensation, once the condensation will not happen, the instrument will stop heating.

3.Disconnection warning 

When the heater break down and can not satisfy the requirement of heating, the breakdown pilot lamp will give an alarm. Meanwhile, warning output is usually close.


1.Sensor is fixed to the right position of electric power instruments such as high and low pressure switch cabinets and box type substation, but must keep enough safe distance with high voltage.

2.When the load electricity is bigger than 3A, it can be connected to contactor or middle electric relay, to enlarge output power.

3.The installation of the sensor

       Sensor has high-performance, is fixed to the proper position of the cabinet.

How to use

1.Connect the line as picture shows, after turn on the electricity, the pilot lamp of the electrical source light, when the temperature is too low and satisfy the requirement of heating, the lamp light and mean the heater is working. When the temperature rises to a certain figure, the heater will stop work automatically.

2.If need text the condensation's heating situation after feel dampness, one can put humidity sensor to the fridge whose temperature is higher than 20ºC to copy the condensation condition, or use the way of breathing upon humidity sensor, and observing the work situation under condensation condition.
