Regular Oil Testing: Ṣe scientific offline testing procedures (bíi per GB/T 7595/IEC 60422), monitoring routine parameters including breakdown voltage, micro-water content, dielectric dissipation factor (tan δ), acid number, dissolved gas analysis (DGA), etc. Implement rapid response to abnormal indicators.
Online Monitoring Technology: Deploy online monitoring devices for parameters like oil moisture content, dissolved gas, and micro-particle count, enabling real-time visualization of oil condition and transitioning from time-based to condition-based maintenance.

Purification and Regeneration: Employ vacuum oil processing units (incorporating efficient dehydration, degassing, and precision filtration modules) for periodic oil filtration to remove moisture, gases, and solid contaminants. For oils with excessive acid number or tan δ but relatively mild aging, utilize adsorption regeneration (e.g., molecular sieve, silica gel treatment) or thermosiphon oil purifier technology to restore performance and extend oil change intervals.
Scientific Oil Replacement: Strictly execute oil replacement procedures according to specifications when oil degradation is severe or aging by-products cannot be effectively removed. Ensure new oil meets standards before injection, and strictly control dust and moisture during the replacement process.

Sealing Upgrade: Replace traditional materials with aging-resistant EPDM (Ethylene Propylene Diene Monomer) or fluoroelastomer seals, optimizing seal structure design for interfaces like flanges, valves, and bushings. For large transformers, equip with bellows-type conservator tanks (featuring dual-seal technology) to compensate for oil volume changes, maintain positive pressure, and completely isolate against external air and moisture intrusion.
Environmental Control: Install high-efficiency desiccant breathers (using silica gel/activated alumina) at tank vents, and regularly inspect/replace desiccant to ensure no moisture ingress during breathing. Maintain transformer rooms/oil pits dry and clean.

Ẹ̀kọ́ Long-Term:

Enhanced Reliability: Padà ẹ̀ka unplanned outage rates caused by insulation or oil quality issues, ensuring continuous grid power supply capability.
Optimized Economic Efficiency: Extend major overhaul and oil change intervals, reducing maintenance resource consumption; significantly postpone the need for large-scale retrofits or replacements (enhancing lifecycle value).
Extended Lifespan: Comprehensive measures effectively delay the aging of critical components, enabling transformers to reach or exceed design life (extending lifespan by 5 to 15 years depending on operating conditions).
Safety Compliance: Meet mandatory requirements for insulation performance and oil quality management stipulated in electrical equipment preventive testing regulations and environmental laws.

IV. Ẹ̀kọ́ àti Implementation

Stringent Supplier Selection: Procure key materials (insulation paper, oil, seals) from top-tier brands possessing authoritative certifications (UL, VDE, CESI, etc.).
Standard Operating Procedures (SOP): Develop detailed operating specifications for insulation handling, vacuum oil filling, seal installation, and oil sampling/testing, with mandatory training enforcement.
Digital Platform Support: Utilize condition monitoring data management systems for trend analysis, enabling predictive maintenance decision support.
Expert Consultation: Provide full-cycle professional technical services, from solution customization to on-site guidance.
