Composition of KYN28A-12 high voltage switchgear

Basic structure of KYN28A-12 high voltage switchgear:

1. KYN28A-12 high-voltage switchgear consists of a fixed cabinet and a removable vacuum circuit breaker handcart. The fixed switchgear cabinet is divided into four compartments: the busbar compartment, the circuit breaker compartment, the cable compartment and the low-voltage compartment.

2. The basic cabinet types of the switch cabinet are the incoming cabinet and the feeder cabinet. In addition to the basic cabinet type, there are other derivative schemes, such as busbar sectional cabinets, metering cabinets, PT cabinets, used transformer cabinets, etc.

3. In addition, there are plans to configure fixed load switch, vacuum contactor handcart, isolation handcart, etc.

4. The switch cabinet is installed against the wall or face to face, which can fully meet the specific requirements of the site.

5. In the busbar sectional system, there must be two dedicated switch cabinets, namely the busbar connection cabinet with the circuit breaker handcart and the isolation cabinet (it may also be a PT cabinet or a metering cabinet).
