High Voltage Centrally Installed Switchgear

KYN28
KYN28-12 armored center-mounted AC metal-enclosed switchgear (hereinafter referred to as the switchgear) is a new product designed and developed by ourselves on the basis of absorbing advanced manufacturing technology at home and abroad. It can replace various old-type metal-enclosed switchgear and is suitable for 3.6 -12kV three-phase AC 50HZ power grid, used as a receiving and distribution cabinet, and for controlling, monitoring and protecting circuits. It can be used in single bus, single bus segment or multi-bus systems.
The switchgear complies with the requirements of standards such as IEC298 "AC Metal-Enclosed Switchgear and Control Equipment with Rated Voltage Above 1kV and 12kV and Below", IEC594 "Common Terms for High-voltage Switches and Control Equipment", and "my country's GB3906 3.6-40.5kV AC Metal-Enclosed Switchgear". . It has reliable "five prevention" functions and has passed the internal arc test. It is a power distribution equipment with superior performance.
1. The cabinet structure is assembled by multiple bending of aluminum-zinc plates.
2. Completely metal armored and completely segmented.
3. All equipment operations can be performed with the cabinet door closed.
4. The cabinet shell is highly sealed to prevent the equipment from being invaded by debris and pests, and the protection level is IP4X.
5. Simple and effective locking to prevent misoperation.
6. It can be equipped with ZN63 (VS1), ZN12 vacuum circuit breaker handcart, imported VD4 (ABB), Ev12 (Schneider), 3AH (Siemens) vacuum circuit breaker handcart.
7. The machine groove mechanism of the vacuum circuit breaker in the high-voltage chamber requires only a small amount of maintenance.
8. The cabinet can be installed on the wall and maintained in front of the cabinet to reduce the floor space.
9. The cable room has ample space. Multiple cables can be connected.
10. Through the panel door, it is easy to observe the cable and installation conditions.
11. Quick grounding, switch is used for grounding and circuit short circuit.
12. It is very simple to replace the circuit breaker, and the handcart has good interchangeability.
