Abstract

A diaryl alkane isolating oil, the molecule structure formula of it is I, the R1, R2 and R3 represents H or CH3 separately. This isolating oil can be as the immersion oil of some condenser, and it can be as the immersion of paper mediator, paper membrane complex mediator and whole membrane mediator. It especially is suitable to the immersion of high pressure whole polypropylene membrane. The aromatic and fat element of this invention are optimizing combination, and this improves the aroma of the isolating oil further and decreases the viscosity of the isolating oil at low temperature, so the electric field resistance of the isolating oil during the whole usage processes is stable. It can be applied to the higher intensity of working electric field.

Description

technical field

[0001] The invention relates to an impregnating agent for a capacitor insulating medium, in particular to a diaryl alkane insulating oil, which is mainly used as an impregnating agent for a high-voltage polypropylene full-film dielectric power capacitor. Background technique

[0002] At present, the impregnants for high-voltage full-film power capacitors mainly use the following types:

[0003] One is diarylethane, such as phenylxylylethane (PXE), phenylethylphenylethane (PEPE), etc. Because phenylxylylethane and phenylethylphenylethane have good insulating properties and good compatibility with polypropylene film, they have been widely used in the power capacitor manufacturing industry. However, its electrical aging performance in the high and low temperature range is poor, and the working electric field strength it bears is low.

[0004] The other is monobenzyltoluene and dibenzyltoluene (M / DBT) blended oil. Although its performance is improved compared t...
