The most commonly used high voltage switchgear, which has several 1, High Voltage Switchgear structure can be divided into fixed and withdrawable two kinds. 2, fixed switch in the main KGN and XGN series, Yanjin County, low voltage, the old model GG-1A type basically eliminated. 3. Remove the switchgear mainly JYN and KYN series, the most representative is KYN28 high-voltage withdrawable switchgear; withdrawable switchgear no isolating switch, because the circuit breaker after the move to form a break open points, it does not require isolation switch. 4, there are some foreign brands of switchgear, low voltage Puyang City, the manufacturers have their own numbering, you can check online. MNS Low-voltage withdrawable switchgear ※ PURPOSE: MNS AC low-voltage power distribution equipment for power plants, substations, industrial enterprises and other power users of AC 50Hz, rated working voltage of 660V, rated current up to 3200A power distribution system , as power, lighting and power distribution equipment, power conversion and consumption equipment control purposes. ※ Main features: First, the product is mainly a combination of power distribution, lighting, motor control unit and other functional units from the program can be any combination. And with a sound grounding and protection systems, not only to meet the three-phase three-wire and three-phase four-wire system, low voltage, and to meet the three-phase five-wire system. Second, the cabinet is divided into horizontal bus zone, vertical bus bar area, cable installation area of ??the four areas and isolated areas, functional units in the device installed in their respective area of ??the closet, when any one functional unit accident, you can quickly cut off (or replace the spare functional unit), does not affect the normal work of other functional units, expanding prevented the accident. Third, the functional unit Installation: drawer, fixed interval type, you can choose according to need. Fourth, all functional units can press performance regulations breaking current. Puyang City, low voltage, low voltage, provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co. Connaught. Henan Xi Connaught Electrical Equipment Co.
