Electric fluids are long-term circulating functional mediums for electrical equipment insulation and heat dissipation, and their performance status directly affects the operational safety and service life of power, electronic, and new energy equipment. Long-term high-temperature operation, moisture intrusion, impurity mixing, and oxidation aging will lead to performance degradation of electric fluids, reducing insulation and heat dissipation efficiency, and easily causing equipment short circuit, overheating, and failure. Scientific daily maintenance and regular testing can effectively extend the service life of electric fluids and ensure the stable operation of electrical systems.
Regular performance testing is the core of electric fluid maintenance. Enterprises need to regularly detect key indicators such as dielectric strength, moisture content, viscosity, acid value, and impurity content of circulating electric fluids. Dielectric strength is the most critical indicator; a significant drop indicates moisture or impurity pollution in the fluid, which needs timely filtration or replacement. Excessive moisture content will seriously damage insulation performance, while increased acid value means fluid oxidation aging, which will corrode equipment metal components. Regular professional testing can accurately judge fluid performance status and avoid potential safety hazards caused by invisible performance degradation.
Sealing protection and environment control are key to preventing electric fluid deterioration. Electric fluid circulation systems must maintain good sealing performance to avoid air and moisture intrusion. Long-term contact with air will accelerate fluid oxidation and aging, while moisture mixing will directly reduce dielectric strength. For equipment working in humid, dusty, and high-pollution environments, regular inspection of system seals, breathing valves, and filter devices is required to ensure no air leakage, water ingress, and impurity inhalation. In addition, avoid long-term overload operation of equipment; excessive operating temperature will accelerate fluid molecular cracking and aging, shortening service life.
Timely filtration and scientific replacement are essential maintenance measures. For slightly deteriorated electric fluids with impurities and suspended matter, professional filtering equipment can be used to remove particulate impurities and moisture, restoring partial performance and extending service life. When the fluid has obvious aging phenomena such as decreased dielectric strength, increased acid value, dark color, and sludge precipitation, it must be completely replaced in a timely manner. During replacement, thoroughly clean the system pipeline and equipment interior to avoid residual old fluid impurities affecting new fluid performance. Waste electric fluids need to be recycled and disposed of in accordance with environmental protection regulations to avoid environmental pollution. Standardized electric fluid maintenance can reduce equipment failure rates by more than 40%, extend fluid service life by 30%, and greatly reduce enterprise equipment operation and maintenance costs.
