AI Technical Summary
Existing impregnating agents for power capacitors are difficult to balance environmental friendliness and gas absorption performance. Mineral oil-based impregnating agents pollute the environment, synthetic impregnating agents are toxic and have complex production processes, while natural ester-based impregnating agents have high viscosity and weak gas absorption performance.
Natural terpenoid compounds are used as gas absorption performance enhancers. Combinations of monoterpenes, sesquiterpenes, diterpenes, triterpenes, tetraterpenes and polyterpenes and their derivatives are used to prepare impregnating agents for power capacitors. Gas absorption efficiency is improved through physical adsorption and weak chemical interactions, while taking into account both environmental protection performance and low-temperature fluidity.
It significantly improves the gas absorption efficiency of power capacitors, with a biodegradability rate of up to 90%, meeting the standards for green power equipment. Moreover, the manufacturing process is simple, low-cost, and extends the service life of capacitors.
