A well-structured maintenance plan for our Gas Insulated Switchgear involves several key activities. Adhering to the schedule outlined below ensures optimal performance.
-
Regular Inspections: Visual checks for any signs of physical damage, corrosion, or leakage points.
-
SF6 Gas Monitoring: Continuous monitoring of gas pressure and purity is critical. Annual checks for moisture content and decomposition by-products are recommended.
-
Contact Resistance Measurement: Periodic testing to ensure the health of primary circuit contacts and to identify any abnormal wear.
-
Functionality Tests: Regular operation of circuit breakers, disconnect switches, and earthing switches to verify mechanical integrity.
-
Heater and Dehumidifier Check: Inspection of all cabinetry heaters and moisture control systems to prevent condensation.
The following table summarizes the core maintenance parameters for a CONSO·CN Gas Insulated Switchgear unit, highlighting our product's robust design.
| Maintenance Parameter | Standard Value at CONSO·CN | Recommended Check Frequency |
|---|---|---|
| SF6 Gas Pressure | 0.5 MPa (at 20°C) | Continuous Monitoring / Annual Detailed Analysis |
| SF6 Gas Moisture Content | < 200 µL/L | Annually |
| Main Circuit Resistance | < 50 µΩ | Every 2 Years or as per load cycles |
| Mechanical Operation | 10,000 operations (circuit breaker) | As per manufacturer's schedule |
Gas Insulated Switchgear FAQ
What is the typical maintenance interval for Gas Insulated Switchgear?
Routine visual and gas monitoring should be conducted quarterly, while comprehensive maintenance, including internal inspections and detailed gas analysis, is typically scheduled every 5 to 10 years, depending on the operational environment and specific CONSO·CN model.
Why is SF6 gas monitoring so important?
SF6 gas is the primary insulating medium. A drop in pressure compromises the dielectric strength, risking internal faults. Furthermore, monitoring for decomposition by-products like SO2 and H2S can help detect early signs of internal arcing or abnormal heating.
Can the maintenance be performed with the switchgear energized?
Many external checks, such as visual inspections, gas pressure readings, and some functionality tests, can be done while the equipment is energized. However, any internal inspection or repair requires the Gas Insulated Switchgear to be fully de-energized, isolated, and grounded for absolute safety, following strict protocols.
