      Function of temperature relay

      Release date:2020-01-16 The author: Click on:

      When the motor is overloaded, the winding temperature rise is too high, and the heating element can indirectly reflect the temperature rise of the winding, and the thermal relay can play the role of motor overload protection. However, even if the motor is not overloaded, because the voltage rise, but also increase the iron loss of motor and core heat, this also causes the winding temperature is too high, or the motor temperature is too high, bad ventilation, also makes the winding temperature is too high. After the emergence of the two case, if you can not use a thermal relay. To this end, there is a temperature principle of the relay, which is the temperature relay. The temperature relay is a kind of miniature overheat protection element which is sensitive to the temperature change. It is mainly for burying parts in motor heating, such as motor stator end winding groove, etc., can directly reflect the heating situation, whether it is the motor overload current caused by temperature, or other causes of motor temperature rise, the temperature relay can be protected. It is not difficult to see that the temperature relay has "full thermal protection" role. And temperature relay can also be used for other electrical equipment under normal conditions of overheating protection and medium temperature control. Relay manufacturers
