Metal-clad Movable Switchgear

Metal-clad Movable Switchgear

KYN28A-12 indoor metal armored movable switchgear is a complete power distribution device for 3.6kV~12kV, three-phase AC 50/60Hz, single busbar section system. It is mainly used for the transmission and reception of small and medium-sized generators in power plants, the transmission of power distribution and power system substations in factories, mines and enterprises, and the start of large high-voltage motors for control, protection and monitoring systems. Comply with GB/T11022, GB/T3906, DL/T404 and other related standards. It has the following functions: prevent the trolley with a load from pushing or pulling the circuit breaker, opening or closing the circuit breaker by mistake, closing the circuit breaker when the grounding switch is in the closed position, entering the electrical room, and closing it by mistake. Interlock grounding switch has electrical functions . It can be used with household VCA and VS1 vacuum circuit breakers, and it can be used with ABB's VD4 and Schneider's EV 12S.

Environmental conditions:

1. Ambient temperature: no more than +40'C and no less than 15C. The average temperature within 24 hours is no more than +35C.

2. Altitude: not more than 1000m.

3. Relative humidity: daily average value does not exceed 95%, monthly average value does not exceed 90%.

4. Earthquake intensity: no more than 8 degrees.

5. Vapor pressure: the daily average value does not exceed 2.2kPa, and the monthly average value does not exceed 1.8kPa.

6. The installation site is free of fire, explosion, serious pollution, chemical corrosion and severe vibration.

Feature of product:

1. The cabinet and partitions are made of hot-dipped AI-Zn alloy coated steel plate and frame, using multiple bending technology, which has high overall strength and good grounding.

2. Fully consider the operating characteristics of the neutral point of the power system that is not grounded or grounded by the arc suppression coil, increase the insulation gap, and improve the insulation level to ensure that the switchgear meets the higher insulation strength requirements.

3. Complete metal coating and absolute barrier separation.

4. The protection level is IP4X, which effectively prevents the equipment from being invaded by debris and pests.

5. Simple and effective mechanical stopper five preventions to prevent misoperation.

6. The movable trolley adopts a worm gear propulsion mechanism. The same type of trolley can be completely interchanged, easy to operate and maintain.

7. It can be installed far away from the wall, which is more convenient for double-sided maintenance. It can also be installed against the wall and kept on the front of the cabinet to reduce space occupation.

The panel width is 550mm in 8 minutes, which can improve the utilization rate of the power distribution room.

9. Through strict condensation, contamination and internal arc tolerance tests, the product runs safely and reliably.
