KYN28A-12 Removable AC Metal-Clad Switchgear (12kV)

KYN28A-12 Armored Removable AC Metal Enclosed Switchgear

KYN28A-12 armored removable AC metal enclosed switchgear (hereinafter referred to as switchgear) is a complete set of power distribution device for 3-12KV three-phase AC 50Hz single bus breaking system, which is mainly used for power transmission of small and medium-sized generators in power plants, power receiving and transmission of industrial, mining, enterprises and institutions as well as the secondary Electrical substation of the power system, and large high-voltage motors for control, protection and detection. This switchgear meets the requirements of IEC298, GB3906, and other standards. It has interlocking functions to prevent loaded push-pull circuit breaker handcart, prevent accidental opening and closing of circuit breakers, prevent closing of circuit breakers when the grounding switch is in the closed position, prevent accidental entry into live compartments, and prevent accidental closing of grounding switches when charged. It is equipped with VS1 (ZN63A) vacuum circuit breakers or imported VN3 vacuum circuit breakers.

Product Mix

The switchgear is designed according to national standards such as GB3906 "3-35kV AC Metal Enclosed Switchgear". The overall structure is composed of two main parts: a cabinet body and a central withdrawable component (i.e. a handcart). The cabinet body has four separate compartments, with an enclosure protection level of IP4X. When the doors of each compartment and circuit breaker room are opened, the protection level is IP2X. Equipped with overhead incoming and outgoing lines, cable incoming and outgoing lines, and other functional schemes, this switchgear can be arranged and combined to form various forms of power distribution devices. It can be installed, debugged, and maintained from the front, so it can be combined back to back into a double arrangement and installed against the wall, improving the safety, flexibility, and reducing the floor area of the switchgear.
