Background
With the development of electrical automation, many industries require powerful motors to aid in their production; during the production process, the motor is often overloaded to operate, which can cause the motor to malfunction.
In the related technology, a high-power motor is mainly protected based on an electric heating principle, a thermal overload relay is arranged as a protection device, the thermal overload relay is an overload relay which applies a current thermal effect principle and takes an electrician thermal sensitive bimetallic strip as a sensitive element, and the overload relay is also called a thermal relay; the electric thermo-sensitive bimetallic strip is formed by heating and rolling two alloys with larger difference of linear expansion coefficients; when heated, the bimetallic strip bends from the high expansion layer (active layer) to the low expansion layer (passive layer). When the current is too large (exceeds a setting value), the element acts due to heat, and the linked break contact cuts off the power supply of the controlled circuit and the protected equipment, so that the motor is subjected to interrupt control.

The thermal overload relay has the problem that the sensitivity is easy to reduce, and the sensitivity of the thermal overload relay is reduced, so that the fault of a motor burning coil is easy to cause; the maintenance of a high-power motor is long in time and high in cost, and the production efficiency is greatly influenced once the motor coil burning fault occurs.
