KYN28-12 High/Medium Hv Mv Voltage AC Metal Clad Electrical Switchgear

KYN28-12 power distribution cabinet is a kind of armored removable central metal switchgear. . The high voltage of the central cabinet is 3.6/7.2/12kv, three types, the common one is 12kv, and the model is KYN28-12 type central cabinet. Indoor high-voltage complete power distribution switchgear.

The structure of the central cabinet is divided into upper, middle and lower layers. The upper layer is the busbar room and the instrument room. The instrument room is in the front, the busbar room is in the back, and the two chambers are separated by a partition. The middle layer is the switch room, which is the compartment where the vacuum circuit breaker is placed. The circuit breaker adopts a handcart-type vacuum circuit breaker, which is easy to install. It only needs to push the circuit breaker trolley out for maintenance and replacement, without powering off. The lower level is a cable room with ample space to connect multiple cables.

Mainly used in power plants, small and medium-sized generators, power distribution in industrial and mining enterprises, and secondary substations in electrical systems for power reception, power transmission, and starting of large high-voltage motors. For the purpose of control, protection and monitoring, this switchgear meets the requirements of DL/T40491, IEC298, GB3906 and other standards. The interlock function of circuit breaker, preventing accidental entry into live compartment, and preventing mistakenly closing the grounding switch when electrified, can be equipped with VS1 vacuum circuit breaker, and can also be equipped with ABB's VD4 vacuum circuit breaker. It is a power distribution device with superior performance.
