GIS switch drive mechanism fault finding, preventing switch refusal and misoperation accidents
GIS is the most important switching equipment in power systems. Whether the switches inside GIS can operate correctly is critical to the safe operation of the power grid. Most high-voltage GIS switch operations rely on hydraulic or compressed air drives. To ensure the normal operation of hydraulic and pneumatic drive systems, motors must be periodically started to build pressure, confirming system performance reliability. However, due to manufacturing defects, installation issues, improper operation and maintenance, or even compressor damage, drive slowdowns and failure incidents are increasing, seriously threatening grid stability and directly impacting people's lives and production with severe social consequences. The electrical equipment PD inspection instrument uses advanced ultrasonic principles and sophisticated sensing technology to vividly detect internal leaks in hydraulic and pneumatic systems, identify drive faults in advance, and inform maintenance personnel through digital and audio alerts for defect elimination, ensuring GIS safe operation.
Internal PD fault detection for GIS/GCB, switchgear, power cabinets, and communication cabinets
Internal PD faults in GIS/GCB and control room switchgear at power plants and substations across various regions are increasing, creating an urgent need for suitable detection methods for predictive maintenance and alarming. The electrical equipment PD inspection instrument arrives at the right time. GIS/GCB have different insulating media, and internal/external PD propagation speeds also differ. Traditional detection methods such as chromatography or electrical testing are not only cumbersome and dangerous, but also expensive and incapable of real-time detection. Electrical O&M personnel urgently need a simple, affordable, and safe detection method for spring inspections, autumn inspections, and routine predictive maintenance. The electrical equipment PD inspection instrument fully meets these requirements.
