The 7S‑SQ‑D is a spring‑stored electric operating mechanism specially designed for SM6 series air‑insulated switchgear. As a core product of Xizi Energy, It drives fixed three‑position disconnectors and earthing switches to realize remote electric operation and automatic control of switch equipment.
It is widely used in incoming/outgoing cabinets, busbar sectionalizing cabinets, metering cabinets and other power distribution scenarios, with high stability, safety and long service life.
（1）Special customized for SM6 cabinet fixed three‑position switches, 100% mechanical interface compatible.
（2）Motor‑driven spring energy storage, instant operation release, no continuous power supply required.
（3）Built‑in cam mechanical program lock to enforce operation sequence and prevent misoperation.
（4）Fast energy storage ≤10s, operation action ≤3s, high efficiency for automatic systems.
（5）Low power consumption, suitable for DC48V, 110V, 220V or AC220V power supply.
（6）Protection class IP54, strong environmental adaptability for distribution rooms.
（1）Complete five‑prevention interlock design with circuit breaker, cabinet door and other parts.
（2）Physical anti‑misoperation structure: prevents earthing switch closing under live conditions.
（3）Mechanical self‑locking after operation to avoid accidental displacement.
（4）Dual position indication: mechanical window display + auxiliary contact remote feedback.
（5）Stable and reliable interlock interface to meet power system safety standards.
