Voltage switchgear and transformer switchgear cabinet selection problem is an electrical device, outside the first master switch into the cabinet, and then enter the sub-control switch, each branch according to need. Such as instrumentation, automation, motor magnetic switch, Kaifeng low voltage switch, a variety of exchanges and contacts, and some also set up the high-pressure chamber and the low-voltage switchgear room with high-voltage bus, low voltage switch cabinet how? Such as power plants, and some also have to protect the main equipment of low cycle load shedding .1, vacuum circuit breakers high voltage switchgear inside the car after closing the test position, the car can not enter the work breaker position. (To prevent closing with load) 2, High Voltage Switchgear ground knife within close position, the car can not enter the circuit breaker closing. (With a ground wire to prevent closing) 3, high voltage switchgear vacuum circuit breaker in the closing work within and panel back door and door lock with a mechanical knife on the ground. (To prevent mistakenly charged interval) .4, vacuum circuit breakers high voltage switchgear at work within the closing, ground knife can not be put together. (Antistatic articulated ground) 5, the vacuum circuit breaker at work within high voltage switchgear closing operation, you can not quit working position car breaker. (To prevent negative Hera Knife) 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 working current up to 3200A of the distribution system, as the energy conversion power, lighting and power distribution equipment and consumable 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, 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, low voltage switch cabinet principle, (or replace the spare functional unit), low voltage switch procurement, 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. Low voltage switch cabinet models _ _ Kaifeng low voltage provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co. Connaught.
