绝缘油(又称介电液体)是一种绝缘介质,由于这种液体具有良好的电气和理化性能,能提高电器设备的着火(击穿)安全性和电容器的储电量,因此是电气装置中必需的一种材料。自从1960年发现已沿用近半个世纪的多氯联苯绝缘油,对生物环境有严重的污染,相继发生中毒事故,促使研究新的绝缘介质以取代多氯联苯,这对保护环境和 Insulating oil (also known as dielectric fluid) is an insulating medium, because of this liquid has good electrical and physical properties, can improve the electrical equipment, fire (breakdown) security and capacitor storage capacity, so the electrical device A necessary material. Since 1960, it has been found that nearly half a century of PCB insulation oil has been used, causing serious pollution to the biological environment and causing successive poisoning accidents, prompting the study of new insulating media to replace PCBs. This is of great significance to environmental protection and
