Product introduction
KYN28A-12 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a complete set of 3-10kv three-phase AC 50HZ single-female breaking system. It is mainly used for small and medium-sized generators in power plants, industrial and mining enterprises. Control, protection, and detection are used for power reception, power transmission, and large-scale high-voltage motors in secondary power substations of business and power systems. The switchgear meets the requirements of IEC298, GB 3906 and other standards. It has the function of preventing the push-pull circuit breaker with load, preventing mis-separation of the circuit breaker, preventing the grounding switch from closing the circuit breaker when it is in the closed position, preventing accidental entry into the live compartment, and preventing Mismatch the grounding switch's interlock function when energized, with VS1 (ZN63A) vacuum circuit breaker or imported VD4 vacuum circuit breaker or Fuji Electric HS vacuum circuit breaker.

product structure
The switchgear is designed according to national standards such as GB3906 "3~35kv AC metal-enclosed switchgear". The whole body is composed of two parts: the cabinet and the centrally-dischargeable parts (ie the handcart). The cabinet has four separate compartments, the protection level of the enclosure is IP4X, and the protection level is IP2X when the compartments and the circuit breaker compartment door are opened. . With overhead access lines, cable access lines and other functional solutions, they can be combined into a variety of distribution devices. The switchgear can be installed, commissioned and maintained from the front, so it can be combined back-to-back into a double arrangement and mounted against the wall, improving the safety and flexibility of the switchgear. Reduced floor space.
