The role of the NTC thermostat

　　1. Thermostat, according to the temperature change of the working environment, physical deformation occurs inside the switch, resulting in some special effects and a series of automatic control elements that turn on or off, also called temperature-controlled switches, Temperature protector, temperature controller, referred to as temperature controller. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller sends a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect. Its application range is very wide. Home appliances, motors, refrigeration or heating and many other products.

　　2. Its working principle is to automatically sample and monitor the ambient temperature through the temperature sensor. When the ambient temperature is higher than the control set value, the control circuit starts, and the control hysteresis can be set. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function will be activated. When the controlled temperature cannot be effectively controlled, in order to prevent the equipment from being damaged, the equipment can also be stopped by the function of tripping to continue running. Mainly used in various high and low voltage switch cabinets, dry-type transformers, box-type substations and other related temperature application fields used in the power sector.
