High Voltage Switchgear main points of fixed and withdrawable type two; as regards the structure was divided into open, semi-enclosed, closed; inner have on the environment in terms of indoor and outdoor points; it has a mode of operation in terms of electromagnetic operating mechanism, spring-operated mechanism and a manual operator. Selection of high voltage switchgear, the decision to use the environment within the selected user type or outdoor type according to the switchgear according to the number and amount of reliability requirements were determined using fixed or withdrawable switchgear. Fixed switchgear prices cheaper, but not as flexible as withdrawable. High reliability requirements, however, the number of switch counter and fewer substations, low voltage Puyang City, try to use fixed switchgear to reduce investment. To determine the combination of high switchgear wiring design of a program, a program can be found in the relevant switchgear electrical manuals. Combined with control, metering, protection, signal and other requirements, select or design their own secondary wiring. After you have selected the main components of the switchgear cabinet according to conditions (altitude, ambient temperature, relative humidity, sunshine, wind speed, daily temperature, etc.) and short-verified. When the operating mechanism is selected, in conjunction with the power substations operating conditions. There DC operating power (silicon rectifier, batteries, etc.) to maximize the use of the electromagnetic operating mechanism. Small substations with manual operating mechanism is relatively simple, low voltage, but the switching cabinet off the flow to weaken a lot. When ordering information should be provided by the manufacturer of high voltage switchgear in general are: 1. High Voltage Switchgear model, a line protocol number, substation secondary wiring diagram and operating mechanism is equipped with a 2. High Voltage Switchgear floorplan 3. High voltage Secondary switchgear wiring diagrams and terminal diagrams; when secondary wiring standard atlases program selected program number and should indicate the voltage control circuit 4 when ordering whether cabinet variable device and indicate current Variable ratio transformer 5. The need to use non-standard one or two line program or commissioned manufacturers design, in consultation with the manufacturers of the pressure cabinet KYN18C-12, details of the cabinet for the whole assembly structure, Fangcheng high low-voltage switchgear, cabinet car hanging in the home with the use of the structure. with trolley complete interchangeability specifications. Transmission financial advance, interlocking whole, interlocking reliable, easy to operate. operate all the equipment, including the drivers in the cabinet The move was carried out under the door closed. The device can be wall mounted cabinet before maintenance can be equipped with imported 3AF, 3AH vacuum circuit breakers and other models, and domestic ZN28, ZN65, ZN12 series of vacuum circuit breakers. protection class IP3X Puyang low voltage, Xi Connaught Electrical and Mechanical (online consultation), low voltage is provided by habit Connaught Mechanical and Electrical Equipment Co., Ltd., Henan.
