1, thermostat (Thermostat), according to the temperature changes in the work environment, the physical deformation within the switch, resulting in some special effects, resulting in a series of turn-on or turn off the automatic control components, also known as temperature control switch, Temperature protector, temperature controller, referred to as thermostat. Or through the temperature protection temperature to the temperature controller, the temperature controller issued a switch command to control the operation of the device in order to achieve the desired temperature and energy saving effect, its wide range of applications, according to different types of temperature controller used in Appliances, motors, refrigeration or heating and many other products.

2, Its working principle is through the temperature sensor to automatically sample the ambient temperature, real-time monitoring, when the ambient temperature is higher than the control set point control circuit starts, you can set the control back to the poor. Such as the temperature is still rising, when it rose to set the limit alarm temperature, start overrun alarm function. When the controlled temperature can not be effectively controlled, in order to prevent the destruction of equipment can also be tripping function to stop the equipment to continue running. Mainly used in the power sector using a variety of high and low voltage switchgear, dry-type transformers, box-type substation and other related temperature use.
