Working principle of temperature controller:
the ambient temperature is automatically sampled and monitored by the temperature sensor. When the ambient temperature is higher than the control set value, the control circuit is started and the control return difference can be set. If the temperature is still rising, when the temperature rises to the set temperature point, the overrun alarm function will be started. When the controlled temperature can not be effectively controlled, in order to prevent the damage of the equipment, the device can be stopped by tripping function.
Scope of application
It is used in all kinds of high and low voltage switchgear, dry-type transformer, box type substation and other related temperature application fields.
