Classification and function of High Voltage Switchgear High Voltage Switchgear cabinet equipment for electrical power systems. The role of high voltage switchgear in the power system for power generation, transmission, distribution and low voltage electrical energy conversion process, opening and closing, control and protection. High Voltage Switchgear unit within the main high voltage circuit breakers, high voltage isolation switch, high voltage load switch, high voltage operating agencies. High Voltage Switchgear classification lot of low voltage equipment, such as through the circuit breaker can be mounted into withdrawable and fixed high voltage switchgear high voltage switchgear, or in a different cabinet structure, divided into open high voltage switchgear, metal-enclosed box-type high voltage switchgear, metal-enclosed high voltage switchgear and interval-type metal-enclosed high voltage switchgear and other armored. High Voltage Switchgear design criteria? ?
