XGN-12D equipped with SPE type spring operating mechanism is accessory equipment for 12kV AC metal-enclosed switchgear. This series of mechanisms uses a planar spiral spring to control load switch operation, and earthing operation is controlled by a compression spring over-center mechanism. The working positions include closed, open, and earthed — mechanical interlock between closed and earthed positions prevents incorrect operation. Mechanism output angle is approx. 80°, average closing and opening speed ≥ 3 m/s, mechanical endurance: 5000 operations for closing, 3000 for earthing. The mechanism features a compact design, easy installation and operation, and strong adaptability.
This product complies with GB3804-2004 “3.6kV ~ 40.5kV AC high-voltage load switches” and GB16926-1997 “AC high-voltage load switch-fuse combination apparatus”.
