Impregnant used by capacitor and preparation method thereof

Abstract

The invention discloses an impregnant used by a capacitor, and relates to the technical field of capacitor manufacturing. The impregnant used by a capacitor is prepared by the following ingredients: 53 to 57 parts of soybean oil, 43 to 47 parts of olive oil, 8 to 10 parts of vitamin E, 50 to 52 parts of accessory powder, 35 to 37 parts of bentonite, 20 to 22 parts of clay, 15 to 17 parts of plant ash, 5 to 7 parts of polyisobutylene, 12 to 14 parts of hydrogen peroxide, 15 to 17 parts of acetic acid, and 25 to 27 parts of concentrated sulfuric acid. The impregnant used by the capacitor and the preparation method thereof have the beneficial effects that the preparation is convenient and simple, the ingredients are easy to obtain, the equipment has little investment, operation is easy, and the prepared impregnant used by the capacitor is environmental friendly, free of pollution, good in use effects, strong in high temperature-resistance, good in heat radiation, safe, reliable, and durable in use.

Description

Technical field [0001] The invention relates to the technical field of capacitor preparation, in particular to an impregnant used for capacitors and a preparation method thereof. Background technique [0002] A capacitor is usually abbreviated as a capacitor. As the name implies, it is a ‘container for holding electricity’, a device that holds electrical charges. Capacitors are one of the most widely used electronic components in electronic equipment. They are widely used in circuits for blocking, coupling, bypassing, filtering, tuning loops, energy conversion, and control. The existing capacitor structure is composed of a shell, an end cover, a capacitor core, an impregnant and a terminal. The impregnant is generally potted between the capacitor cores, and the impregnant is generally made of ordinary vegetable oil. The body of vegetable oil contains a lot of water, and a series of problems such as deterioration of vegetable oil will exist for a long time, which seriously affect...

AI Technical Summary

Problems solved by technology

The existing capacitor structure is composed of a shell, an end cover, a capacitor core, an impregnating agent and terminals. The impregnating agent is generally potted between the capacitor cores. The impregnating agent is generally made of ordinary vegetable oil, but due to The nature of vegetable oil contains a lot of water, and after a long time, there will be a series of problems such as deterioration of vegetable oil, which seriously affects the service life of capacitors, and the use effect is extremely poor.
