The double temperature control electrothermal energy storage structure is used to gradually release heat energy. It is equipped with automatic overheating protection device and automatic insulation indication device. A small electric furnace is controlled by PTC thermistor switch. PTC is a thermistor with positive temperature coefficient. When the current passes through, it will heat itself (the heat of the electric furnace will also be transmitted to it). When the temperature reaches a certain value, its resistance will increase sharply, It can be regarded as disconnection. At this time, the electric heating treasure reduces the consumed electric energy, and then releases heat slowly by insulating the circuit with insulating cotton.
Principle of motor thermal protection: 1: when the motor has overload current, the bimetallic sheet in the thermal protection will bend (because the heating coefficient will be rapidly different after the current of two metal sheets exceeds the set current). A normally closed contact is mechanically connected on the bimetallic sheet, which acts because of bending. The normally closed point is connected in series in the AC contactor in the power circuit, Therefore, the normally closed point of thermal protection acts, the coil of AC contactor is powered off, the main circuit is powered off at the same time, and the motor is protected.

In cold winter, with an electric hand warmer, you won't be cold.
