Product Description

KYN type high-voltage switchgear is a metal enclosed armored movable indoor switchgear, with a three-phase AC 50Hz indoor complete distribution device. As a power plant, substation, and industrial and mining enterprise receiving and distributing three-phase electricity from 50Hz, 10kV/35kV power grids, it plays a role in controlling, protecting, and detecting circuits, and can also be used in frequently operated places, with a complete "five prevention" function.


Product features

1. The switchgear cabinet adopts a completely metal armored and fully enclosed structure; Each isolation room of the switchgear is independent of each other; Quick closing grounding switch for grounding and manual short circuit

2. The circuit breaker can be opened and closed, pushed in and out, and the grounding switch can be opened and closed with the cabinet door closed;

3. Adopting a five proof interlocking device to effectively prevent misoperation and accidental entry into the live interval;

4. The cabinet is equipped with a convenient door panel observation window, which can view the opening and closing status of the circuit breaker, handcart position, energy storage status, grounding switch opening and closing status, etc;

5. Seal and block the outer shell of the cabinet to prevent equipment from being invaded by debris and pests;

6. Install a maintenance free vacuum circuit breaker handcart, and the supporting operating mechanism only requires a small amount of maintenance;

7. The secondary wire radiates into a spacious wire duct, which is aesthetically pleasing and easy to locate.
