The 7S-SQ-D is a spring-stored electric operating mechanism specifically designed for the SM6 series air-insulated switch cabinets.
It is mainly used to drive the fixed three-position disconnectors/grounding switches, enabling the electric operation and automatic control of the switch equipment.
• Specialized Design: Specifically customized for the SM6 cabinet-type fixed three-position switch, the mechanical interface is fully compatible
• Spring Energy Storage Mechanism: Motor-driven spring energy storage, the operation is completed instantly upon release, not relying on continuous power supply
• Forced Mechanical Program Lock: Built-in cam mechanism to enforce the operation sequence, preventing jumping position operations
• Integrated Five-Prevention Interlock: Achieves complete mechanical and electrical interlocking with circuit breakers, cabinet doors, etc.
• Anti-misoperation Design: Physically prevents malicious misoperations such as closing the grounding switch while energized
• Self-Preservation of Status: Mechanical locking occurs after the operation is completed to prevent accidental displacement
• Dual Status Indicators: Local display through mechanical window + remote signal feedback via auxiliary contacts
• Fast Response: Storage time ≤ 10 seconds, operation time ≤ 3 seconds
• Low Power Consumption: The storage motor has moderate power, suitable for DC system power supply
• Environmental Adaptability: Protection level IP54, suitable for distribution room environment
