Problems solved by technology

But the flash point of the environment-friendly transformer oil whose publication number is CN101230304A is about 215°C, which cannot meet the requirement of being a flame retardant oil, which limits its application in places with high fire resistance
Secondly, the anti-oxidation stability of the environment-friendly transformer oil needs to be further improved

Abstract

The invention provides environment-friendly insulating oil which takes vegetable oil as the raw material, and has high flash point and anti-oxidation stability, consists essentially of triglyceride and antioxidant, and also contains a metal deactivator in the further technical proposal. The environment-friendly insulating oil is prepared by refinement by taking vegetable oil as the raw material, does not contain toxic substances, dose not cause damage to environment and human body, and can be rapidly and thoroughly biodegraded, is environment-friendly insulating liquid, and can be applied in places with requirement of high fireproof performance as the flash point and the fire point thereof are both higher than 300 DEG C; the risk of fire and explosion is far lower than that of the traditional transformer oil; and all other performance indexes fully conform to the national standard GB 2536-90 of mineral transformer oil.

Description

technical field [0001] The invention relates to an environment-friendly insulating oil which takes vegetable oil as raw material. Background technique [0002] Insulating oil is an important liquid insulating medium, which is widely used in electrical equipment such as transformers. Mineral insulating oil is widely used in the manufacture of electrical equipment due to its low cost, good insulation performance and cooling performance. However, the biodegradability of mineral insulating oil is poor. Once a serious leakage occurs, it will cause serious pollution to the surrounding soil, water sources and even public communities; moreover, mineral insulating oil has a low ignition point, poor high temperature resistance and fire resistance, and is not suitable for use in mines and mines. , military facilities, high-rise buildings and other places with high fire safety requirements; at the same time, natural oil reserves are limited, and it is expected that there will be a seri...
