The relay protector in High-voltage switchgear is a comprehensive relay protection equipment, whose operating principle is mainly designed and manufactured according to the working mode of microprocessors. It has a scientific and technological foundation and plays an important role in the operation of power equipment, effectively ensuring the good and stable operation of the equipment.

Relays in high voltage motor circuits are fully automatic and intelligent electronic control devices that can achieve effective and precise control of small currents over large currents. The structure of relay protection is relatively complex, mainly composed of two parts: the control system, also known as the input circuit, and the controlled system, also known as the output circuit.

The main application scope is to enable effective automatic control of powerful currents in High and low voltage switchgear circuits, forming automatic regulation, safety protection, and conversion circuits for electrical equipment.

With the development of society and economic construction, higher requirements have been put forward for the stability of power supply. Currently, some power plants have improved the automation level of their electrical systems, especially the use of relay protectors, which greatly ensures the stability and safety of power supply and plays a very important role in the development of power plants. Only by comprehensively doing a good job in setting and recalibrating relay protectors can power plants operate and ensure stable power supply and consumption.
