Prefabricated Substation Maintenance Guide
Standard maintenance is essential to keep prefabricated substations running stably and prolong their service life in long-term operation.
How to Maintain
Carry out regular inspections and targeted maintenance for the prefabricated substation by stages.
Daily Inspection
Check the overall appearance, enclosure sealing, and internal equipment of the prefabricated substation every day. Ensure there is no water leakage, deformation, or abnormal noise inside the prefabricated substation, and verify the normal operation of the lights and monitoring devices.
Daily Inspection Checklist
| Inspection Item | Inspection Content | Standard Requirement |
|---|---|---|
| Cabin Appearance | Shell, doors and windows | No deformation, damage, or water seepage |
| Environmental Status | Temperature, humidity, condensation | Within standard range, no condensation |
| Electrical Equipment | Operation sound, indicator lights | No abnormal noise, lights display normally |
| Auxiliary System | Monitoring, ventilation devices | Run stably without faults. |
Monthly & Quarterly Inspection
Perform in-depth cleaning and performance tests on the prefabricated substation monthly and quarterly. Fasten loose bolts, clean dust on electrical components, check anti-corrosion layers, test fire protection and ventilation systems of the prefabricated substation, and replace aged sealing parts in a timely manner.
Monthly & Quarterly Inspection Checklist
| Inspection Item | Inspection Content | Standard Requirement |
|---|---|---|
| Structural Parts | Bolts, welds, sealing strips | No looseness or aging, good sealing |
| Anti-corrosion Layer | Surface coating | No peeling or rust |
| Electrical Components | Dust, wiring, grounding | Clean surface, firm wiring, qualified grounding |
| Fire & Ventilation | Fire devices, ventilation system | Normal function, smooth air duct |
Annual Inspection
Conduct comprehensive performance testing and overhaul for the prefabricated substation every year. Complete equipment calibration, circuit safety tests, and anti-corrosion repainting of the prefabricated substation, and replenish fire-fighting materials to eliminate potential risks thoroughly.
Annual Inspection Checklist
| Inspection Item | Inspection Content | Standard Requirement |
|---|---|---|
| Whole Cabin Structure | Overall structure, waterproof performance | Firm structure, no water leakage |
| Electrical System | Circuit test, equipment calibration | All indices meet operation standards |
| Anti-corrosion Treatment | Coating maintenance and repainting | Complete rust removal and recoating |
| Fire-fighting Facilities | Agent filling, pipeline inspection | Sufficient medicine, airtight pipeline |
Troubleshooting for Common Faults
Deal with water seepage, condensation, and equipment overheating of the prefabricated substation promptly. Repair damaged seals and blocked ventilation of the prefabricated substation, tighten loose wiring, and cool down overheated parts to restore normal operation.
Safety Operation Notes
Cut off power first before maintaining the prefabricated substation. Wear protective tools strictly, follow operation norms, and avoid illegal operations to prevent electric shock and mechanical injuries.
Summary
Adhere to the tiered maintenance plan for prefabricated substations to minimize faults, extend service life, and ensure safe, stable, long-term operation. Contact us for more information about prefabricated substation enclosures.
