The 7S Series Standardized Switch Bay Secondary Module is a plug-and-play control unit engineered for medium voltage (MV) switchgear and gas-insulated ring main units (RMUs), serving as the critical interface between primary switchgear and secondary protection/automation systems.
1. Modular & Plug-and-Play Design: Pre-wired multi-pin connectors enable quick installation and replacement, reducing downtime during maintenance and upgrades.
2. Dual Control Modes: Supports local manual operation (via push buttons and selector switches) and remote SCADA control, aligning with smart grid automation requirements.
3. Configurable Protection Logic: Protective and control trip/close plugs allow flexible activation/deactivation of protection and remote control functions.
4. High Reliability & Safety: Mechanical interlocks, anti-misoperation design, and IP65-rated enclosure ensure safe operation in industrial environments, complying with power system “five-prevention” standards.
5. Real-Time Status Monitoring: LED indicators provide at-a-glance visibility of switch status (open/closed) and fault conditions, with auxiliary contacts for remote monitoring via SCADA systems.
