Abstract

The invention relates to a biodegradable insulating fluid with a high ignition point: an ester compound A formed by a transesterification reaction of a dibasic acid, a polyol butyrate and a small molecular organic acid under the action of a transesterification catalyst Q; the dibasic acid, Polyol X alkyl butyrate and small molecule organic acid undergo ester exchange reaction under the action of transesterification catalyst Q to generate ester compound B; polyol butyrate and small molecule organic acid undergo esterification under the action of transesterification catalyst Q The ester compound D generated by the exchange reaction; the ester compound E generated by the transesterification reaction of the polyol X alkyl butyrate and the small molecule organic acid under the action of the transesterification catalyst Q; the ester compound A, the ester compound B, Ester compound D and ester compound E are mixed and antioxidant, pour point depressant and metal stabilizer are added. The invention has good compatibility, high ignition point, superior heat conduction performance, anti-aging, and conforms to the IEC61099 quality standard.

Description

technical field [0001] The invention belongs to the technical field of insulating fluid and relates to a biodegradable high ignition point insulating fluid. Background technique [0002] In the process of long-distance transmission of high-voltage power, as well as in the process of electricity consumption in cities, rural areas, industries, and people's livelihood, transformers are indispensable equipment. The transformer generates heat during the distribution and conversion of electric energy. To ensure the normal operation of the transformer, the heat needs to be transferred to the environment with a good heat-conducting heat carrier. This heat carrier should also have good insulation properties. [0003] In the early electric power industry, vegetable oils such as sunflower oil, rapeseed oil, tea tree oil, soybean oil, etc. were widely used as transformer oil. However, these vegetable oils have the disadvantages of easy oxidation and poor stability during use. [0004]...
