KYN-28 (GZS1)-12 AC Metal-Clad Withdrawable Switchgear manufactured by XJ is the packaged power distribution equipment used for rated voltage of 3 ~ 12kV three-phase AC 50Hz single busbar and single busbar sectional system. It is widely used for control, protection and monitoring in different fields, such as for power distribution in large power plants, electricity transmission of small and medium-sized generators, power supply in mining enterprises, power transmission and distribution of secondary substations in electric power system, and starting of large high-voltage motor starter. The switchgear meets the requirements of IEC298, GB3906-1991 and other standards. It features "Five-prevention" locking function: prevent circuit breaker truck from moving with load; prevent misoperation of circuit breaker; prevent grounding switch from closing and opening the circuit breaker at the ON/OFF position; prevent straying into live interval; prevent misoperation of interlocking function of grounding switch with electricity. The switchgear can be fitted and worked with VS1-12 and ZN□-12 type indoor high-voltage vacuum circuit breakers and various functional trucks (disconnection truck, circuit breaker truck, PT truck, metering truck and transformer truck), VD4 12kV medium voltage vacuum circuit breaker manufactured by ABB, EV12 12kV medium voltage vacuum circuit breaker manufactured by Schneider and VEP 12kV medium voltage vacuum circuit breaker manufactured by Huadian and other 12kV medium voltage vacuum circuit breakers manufactured by other domestic and foreign manufacturers. The switchgear may provide a variety of design schemes to meet various design needs. It is really an ideal high-performance distribution device.
