[Product Name]: VS1 (ZN63) breaker [Details]: Overview VS1 (ZN63A) -12 indoor high-voltage circuit breakers for KYN28A-12 high-voltage switchgear in the home is a three-phase AC 50Hz, rated voltage of 12kV. indoor installations, for industrial and mining enterprises, power plants and substations for the control and protection for electrical installations, and for frequent operation place. Use of the environment 1, the ambient temperature is not greater than +40 ℃, not lower than -10 ℃ (-30 ℃ allows storage and transportation); 2, altitude not more than 2000m; 3, air relative humidity on average less than 95%, on average less than 90% of Dongying high-voltage vacuum circuit breakers, the saturated vapor pressure on average less than 2.2 × 10MPa, on average less than 1.8 × 10MPa, the temperature at high temperature during the drop, allowing condensation; 4, seismic intensity not more than 8; 5, no fire, explosion, serious pollution, chemical corrosion and severe vibration of the place please contact us.! There breaker before wiring board after board, plug-in, slide-in, the user if no special request, according to former board supplier, Front connection is a common wiring. 1, after the board wiring: the biggest feature is the rear connection can be replaced or repaired at the circuit breaker, without re-wiring, simply power off the front stage. 2, plug-in terminal: the mounting plate complete sets of equipment, install a circuit breaker mount, the mount 6 plugs, there are six outlet connecting plate breaker. 3 drawer wiring: circuit breaker out of the drawer by joystick clockwise or counterclockwise rotation of the vacuum circuit breaker in the main circuit and secondary circuits are used in the plug-in architecture Liaocheng voltage vacuum circuit breaker, omitted fixed Yantai necessary isolation voltage vacuum circuit breaker, so that a machine with two, improve the economy of use, at the same time to the operation and maintenance has brought great convenience, increased security and reliability. In particular drawer seat main circuit touch knife block, with NT-type knife fuse breaker common touch, so the state of emergency in the power supply can be plugged directly into the fuse. Suqian high voltage vacuum circuit breakers, vacuum circuit breakers, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
