The PCT spring operating mechanism of sf6 switch disconnector is assembled in XGN-12D 12KV AC metal-clad switchgear. It has 3 positions: closed, open and earth, and it has a mechanical interlocking device to prevent misoperation for close and earth. This spring operating mechanism has compact size, easy to install and more applicable.
Type and its meaning:
The series spring mechanisms has two using method:incoming and outgoing, and erery type has two types of operated methods:manual operated and motor operated.
The series spring operating mechanism meets relevant technical requirements of standards GB3804-2004 "3.6KV~40.5KV high-voltage AC load break switch", GB16926-1997 "AC high-voltage load switch- use combinations" of the relevant technical requirements.
Advantages:
1.It has similar dimensions with ABB SFG operating menchanism, so it can be repalced with ABB SFG operating menchanism freely;
2.It has modular construction, compact size,and be easily installed;
3. We developed this mechansim for more than ten years, and have provided a big mount to domestic and overseas markets, and got good feedback from the clients which shows its operating reliability.
