Transmission and distribution equipment, mainly including transformers, cables, distribution switchgear, high-voltage switches, power capacitors, etc., used to transmit the electric energy generated by the generator to each user terminal.
Electrical equipment, after the electrical energy is transmitted to the user terminal, the electrical energy is converted into various forms of energy required for people's life and production through the electrical equipment. Common electrical equipment are lighting equipment, motor, heating equipment, welding equipment and so on.
Control equipment, control equipment is mainly used for electrical process automation control, including PLC, DCS, remote control, remote communication and other equipment.
Protection equipment refers to the automatic protection of electrical equipment in the power system when the electrical equipment fails to ensure the normal operation of the power system. Common protection devices are clamp type grounding protection, microcomputer relay protection and so on.
