Abstract
The invention discloses a preparation method of novel insulating liquid, which is characterized by mixing 1,1-diphenylethane with monobenzyltoluene, antioxidants and epoxy additives according to a certain proportion to form high-performance insulating oil. The insulating oil has the advantages of low dielectric loss, high aromaticity, low viscosity, excellent local discharge performance and the like, can further improve the low-temperature operation performance of a power capacitor and increase the working field strength of the power capacitor, and can be used as a high-performance impregnantfor the power capacitor.
Description
(1) technical field:
The present invention relates to a kind of preparation method of novel insulating liquid, institute's synthetic insulating liquid mainly is used as the soaker of power capacitor.
(2) background technology:
Along with the quick growth of China's generating set installed capacity, new electric transmission and distribution circuit enlarging and the startup of upgrading urban and rural power grids engineering, as the major equipment of power transmission and transformation, power capacitor has obtained developing rapidly.In recent years, the research work of China's power capacitor soaker develops in depth, especially develop with full membranization direction at improving dielectric work field intensity, power capacitor soaker is had higher requirement, research work mainly is by improving the aromaticity of dielectric, improving the work field intensity thereby improve its pumping property; Reduce the pour point of dielectric, improve the shelf depreciation performance, thereby ensure the safe operation of power capacitor.At present, the main products of the power capacitor soaker that generally uses of China has single, double benzyl toluene, diarylethane (PXE) etc.Up-to-date result of study shows, employing is admixed the dielectric that forms with the insulating liquid of different components by certainty ratio, being the effective way that further improves power capacitor soaker pumping property, improves low-temperature performance and local discharge performance, is the developing direction of power capacitor soaker high-end product.
