How to Troubleshoot Common Problems in Air Insulated Switchgear

Efficient power distribution relies on the consistent performance of your switchgear. Air Insulated Switchgear (AIS) remains a cornerstone of electrical networks due to its robustness and cost-effectiveness. However, like any critical equipment, it can encounter issues. Proactive troubleshooting is key to minimizing downtime. At CONSO·CN, we combine deep engineering expertise with our high-performance AIS product line to help you maintain system integrity. Our Air Insulated Switchgear is built with precision, featuring corrosion-resistant enclosures (IP54 rated), durable vacuum circuit breakers with 10,000 mechanical operations, and advanced digital microprocessors for protection and monitoring.

Common Problems & Troubleshooting Steps

A systematic approach to Air Insulated Switchgear issues ensures safety and accuracy. Always de-energize equipment and follow strict lock-out/tag-out (LOTO) procedures before any inspection.

• Problem 1: Overheating Connections

  • Check: Use a thermal camera on busbar joints and cable terminations.

  • Action: Tighten connections to the manufacturer's specified torque. CONSO·CN panels include silver-plated, low-resistance busbars to inherently reduce this risk.

• Problem 2: Circuit Breaker Malfunction

  • Check: Inspect for mechanical wear, coil integrity, and auxiliary contacts.

  • Action: Test the spring-charging mechanism and perform primary injection tests. Our units feature self-diagnostic indicators for quick status assessment.

• Problem 3: Insulation Degradation

  • Check: Look for dust, moisture, or tracking marks on insulating surfaces.

  • Action: Clean components with approved solvents and ensure heater/blower circuits in the enclosure are functional. CONSO·CN's design emphasizes generous creepage and clearance distances.

Air Insulated Switchgear FAQ

Q: How often should preventive maintenance be performed on AIS?
A: The interval depends on the operating environment. For standard conditions, a comprehensive check every 3-5 years is advised. CONSO·CN recommends a yearly visual and thermographic inspection, with detailed maintenance schedules provided in our product manuals.

Q: Can old Air Insulated Switchgear be retrofitted with new digital relays?
A: Yes, retrofitting is often a cost-effective upgrade. CONSO·CN offers compatible retrofit kits that enhance monitoring, protection, and communication capabilities without replacing the entire switchgear assembly.

Q: What is the most critical environmental factor for AIS longevity?
A: Controlling humidity and particulate contamination is paramount. Moisture leads to corrosion and reduces insulation strength. CONSO·CN units come standard with anti-condensation heaters and high ingress protection (IP) ratings to combat these effects.
