[0002] With the continuous advancement of my country's power system reform, China's electrical equipment and power industry are developing rapidly at present, and the scale and power generation capacity of the power grid have ranked first in the world. Problems have formed a diversified power market system. Electrical appliances are important basic components in the power grid with a large quantity and a wide range. The construction of smart grids brings opportunities for the development of smart appliances. The intelligence of the grid is closely related to the intelligence of switching appliances. Relays are A switching device with a large quantity and a wide range, which is mainly used to frequently connect or disconnect the AC main circuit and can be controlled remotely. At present, the energy consumption of most AC relays is very high, resulting in an increase in the temperature control index of the relay. There are potential safety hazards, the performance of the relay is reduced, and the demand for remote control cannot be achieved. It is necessary to develop a new relay to solve the existing problems.
