Working Principle of High Voltage Cabinet and Low Voltage Cabinet
High and low voltage switchgear is the equipment that connects high voltage or low voltage cables. Generally, power supply bureaus and substations use high voltage cabinets, which are then lowered by transformers to low voltage cabinets. Low voltage cabinets are used in the distribution cabinets of each power supply. Inside, some protective devices such as switching circuit breakers are assembled into an integrated electrical equipment. High and low voltage switchgear is divided into low-voltage extraction switchgear, AC low-voltage distribution cabinet, metal armoured removable switchgear, low-voltage fixed partition switchgear, high-voltage capacitor cabinet and high-voltage switchgear.
