Structure and performance
The GN□-12 isolating switch has a novel structure and is a new isolating switch independently developed by the company. The moving and static contacts are installed on two horizontal insulators, and the moving contact is directly driven by the driving spindle to rotate to realize opening, closing and grounding, and has a small installation space. , The busbar is easy to connect, and the fracture is obvious. It is suitable for side-mounted high-voltage cabinets with compact installation height and space. It can be driven by the BET-type mechanism through the other arm without a mechanism, or it can be directly operated by its own operating mechanism, which can be operated at the opening position. Install grounding contacts to achieve protective grounding.
