Example Embodiment

[0017] Example : A capacitor impregnating agent containing modified pottery clay, the weight parts of which are composed of raw materials are: salad oil 105, modified pottery clay 5, modified tree ash 3, siliceous shale 1, nano pottery clay 0.3, diatomite 0.5, potassium long Stone 0.5, Attapulgite 0.8 and Stearic Monoglyceride 0.2.

[0018] The preparation method that contains the capacitor impregnating agent of modified pottery clay, comprises the following steps:

[0019] (1) Preparation of modified clay:

[0020] a. First roast the clay at 450-480°C for 3-4 hours, then soak it in 10-12% hydrochloric acid solution for 3-4 hours, then wash it with deionized water until it is neutral, and dry it;

[0021] b. Add sodium lauryl sulfate equivalent to 2-3% of its weight, 1-2% chlorinated paraffin, 2-3% polyisobutylene, and 3-5% magnesium oxide powder to the clay after the above treatment. Stir at 3200-3500 rpm, dry and pulverize into superfine powder;

[0022] (2) Preparat...

Abstract

The invention discloses a capacitor impregnant containing modified argil and a preparation method thereof. The capacitor impregnant comprises the following raw materials by weight: 103-108 parts of salad oil, 4-6 parts of modified argil, 2-4 parts of modified tree ash, 0.8 part to 1.2 parts of siliceous shale, 0.7-0.9 part of attapulgite and 0.1-0.3 part of stearic acid monoglyceride. The capacitor impregnant adopts the salad oil as a main material and is low in cost. Simultaneously, the modified argil, the modified tree ash, the siliceous shale the attapulgite and the stearic acid monoglyceride are added. Adsorption performance of moisture in the impregant is improved by modifying the argil and the tree ash. The capacitor impregant has good flowability and heat resistance, is free of corrosion and impurity, and is capable of effectively improving electric performance of a capacitor and prolonging service life of the capacitor.

Description

technical field [0001] The invention relates to a capacitor impregnating agent, in particular to a capacitor impregnating agent containing modified clay and a preparation method thereof. Background technique [0002] At present, the impregnating agents used in capacitors are generally vegetable oils such as castor oil and salad oil, or mineral oils such as methyl silicone oil, phenylmethyl silicone oil, and PO oil. The biggest disadvantage of using oils as impregnants for capacitors is that the oil always contains Some moisture, and during the use of the capacitor, the moisture will gradually invade the capacitor core, causing the thin film metal plate of the capacitor to fall off, so that the capacity decays quickly and fails, reducing the life performance of the capacitor. If these oils are dehydrated in advance , requires more complex equipment, costs more, and cannot prevent these oils from getting wet again. Contents of the invention [0003] The purpose of the prese...
