Key Technologies of Intelligent High-Voltage Switchgear
High-voltage switchgear refers to indoor and outdoor AC switching equipment operating in power systems with voltages of 3kV and above and frequencies of 50Hz and below. It is mainly used for the control and protection of power systems (including power plants, substations, transmission and distribution lines, and industrial and mining enterprises), allowing for the switching of power equipment or lines in and out of operation according to grid needs, and quickly isolating faulty sections from the grid in case of equipment or line failures. This ensures the normal operation of the fault-free parts of the grid and the safety of equipment and maintenance personnel. Therefore, high-voltage switchgear is crucial transmission and distribution equipment, and its safe and reliable operation is of great significance to the safe and efficient operation of the power system.
