Outdoor power facilities have to face the test of high temperature, heavy rain, salt fog, thunderstorm and strong wind all year round in tropical Southeast Asia. Daily inspection is the most economical and effective way to reduce failure rate. Many on-site personnel only make random patrols without standardized inspection items, resulting in many hidden dangers being missed until faults break out.
Forming a fixed inspection checklist can standardize daily work, make inspection items clear and not omitted, and greatly improve the safety management level of on-site power system.
| Inspection Category | Core Checking Items | Inspection Focus | Handling Standard |
|---|---|---|---|
| External Overall Status | Shell corrosion, paint peeling, deformation damage | Check salt fog erosion and rainwater soaking trace | Minor rust do anti-corrosion treatment, serious deformation arrange maintenance |
| Sealing & Waterproof Part | Cabinets sealing strip, wiring inlet gap, waterproof cover integrity | Check whether there is gap water seepage and aging deformation | Replace aging sealing accessories immediately, strengthen gap sealing |
| Connection & Fastener | Terminal wiring tightness, bolt looseness, contact oxidation | Check heating trace and discoloration at connection point | Retighten loose parts, clean oxidation and apply protective grease |
| Environmental Adaptation | Equipment surrounding water accumulation, ventilation condition, sundry stacking | Check low-lying waterlogging and heat dissipation obstruction | Dredge drainage in time, clean surrounding sundries and keep ventilation |
| Operation Abnormality | Running noise, shell temperature, voltage stability | Distinguish normal working sound and abnormal resonance | Record abnormal data, arrange electrician to check hidden danger |
It is suggested to implement routine inspection every week in dry season and increase to twice a week in monsoon and thunderstorm season. Record all inspection contents truthfully, form file records, and provide basis for later maintenance and equipment renewal.
