YS Engineering Solution offers specialized Vacuum Circuit Breaker (VCB) Maintenance and Service, a critical process for ensuring the long-term reliability and safe operation of medium-voltage switchgear in industrial power systems. The comprehensive service includes a detailed inspection of the vacuum interrupters to check for potential loss of integrity and an essential examination of the operating mechanism (including the spring-charging motor, closing, and tripping coils). Key maintenance steps involve cleaning and lubrication of all moving parts to ensure smooth operation, alongside crucial electrical testing. This testing includes contact resistance measurement and timing tests to verify that the VCB can accurately and quickly interrupt fault currents, thereby providing robust protection to the entire medium-voltage network.
