vacuum insulation regeneration oil purification (oil filtration, oil purification, oil filter, oil purifier, oil recycling, oil treatment, oil regeneration, oil restoration, oil filtering, waste oil disposal, oil reclaiming, waste oil management, energy saving, oil reconditioned, oil reconstituted, oil restituting, oil recovering) application this machine is used for overhauling and installing the electric insulating equipments which are running as energized, such as transformer, oil switch and mutual inductor. also it is especially applied to regenerate and purify the seriously deteriorated insulation oil and make the oil reach the international standard. the functions include dewatering, degassing, decolor, removing the impurities, free carbon and deep oxides, and recovering the oil’s original function. feature 1. besides the common vacuum oil purifier’s function of dewatering, degassing and eliminating impurities, this machine can regenerate the seriously deteriorated oil by removing the polarity materials, such as the deep oxides, free carbon in the oil effectively. it can make the seriously deteriorated oil reach to the normal index like anti-oxides, acid- alkali water-solubility. 2. three ways of using: the vacuum dewatering, degassing, removing impurities system can work independently, so dose the regeneration oil system, and also they can work at the same time. 3. the performance and lifetime of insulating oil will improve and extend awfully after purification and regeneration. advantage it can not only removing the water, gas and impurities which mixed in the oil, but also can improve many values reach to the national standard such as the acid value, ph value. meanwhile, it improves the voltage-withstand value through filtering the polarity materials like free carbon, deep oxides and so on.
