KYN28A-12 flat-topped cabinet details of the cabinet is made of imported aluminum coated zinc plate steel double folded assembled, is divided into four separate compartments. Meter room and roof design are integrated, the cabinet as a whole simple, reliable, and easy to install. After two doors up and down the cabinet design, user maintenance more convenient. Second go trough optimized design, effectively have to improve the level of protection for the second line. grounding switch central installation, CT lifting, Zhengzhou high and low switchgear principle, increasing the cable room space, making maintenance simple, easy cable installation can be equipped with VS1, VD4 (ABB), EV12 (Schneider), ZN28 (GM), VB2 (GM), 3AH5 (Siemens) series The circuit breaker protection class: shell IP4X, IP2X between compartments of high voltage switchgear mainly consists of fixed and withdrawable type two; as regards the structure was divided into open, semi-enclosed, closed; on the use of the environment. Linguistic have indoor and outdoor points; on the operating mode 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 selected based on user type or outdoor type, Taikang low voltage switch cabinet, according to the number of how many switchgear and reliability requirements, determine the use of 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 switch cabinet Huixian, 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 Kaifeng County low voltage switch cabinet, low voltage, Xi Xi from Henan Connaught Connaught Electrical and Mechanical and Electrical Equipment Co. provided. Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) strong, credible, in Zhengzhou, Henan electronics, electrical products processing industry has accumulated a large number of loyal customers.
