Embodiment Construction

[0040] The following is attached Figure 1-4 The application is described in further detail.

[0041] The embodiment of this application discloses a capacitive voltage equalization system for the main insulation of the rubber-impregnated fiber bushing, please refer to figure 1 , which includes an air side part 1 and an oil side part 2 fixedly connected to one end of the air side part 1 . Among them, the end of the air side part 1 away from the oil side part 2 is connected to the cable, the oil side part 2 is located inside the power distribution cabinet or the transformer, and the air side part 1 and the oil side part 2 form the entire capacitor voltage equalization system to reduce insulation When the inside of the bushing is broken down, it affects the point distribution of the entire insulating bushing, thereby reducing the probability of failure of the insulating bushing.

[0042] Specifically, please refer to figure 1 and figure 2 , the air side part 1 includes an en...

Abstract

The invention relates to a capacitance voltage-sharing system for main insulation of an impregnated fiber sleeve, which belongs to the technical field of insulating sleeves and comprises an air side part and an oil side part fixedly connected with one end of the air side part. The air side part comprises an end connecting assembly, a first core body fixedly connected with one end of the end connecting assembly, an insulating piece arranged on the first core body in a sleeving mode and a core body connecting piece arranged at the end, away from the end connecting assembly, of the first core body. The oil side part comprises a second core body with one end fixedly connected with the first core body and a voltage equalizing piece arranged at the end, away from the first core body, of the second core body, and insulating coatings are arranged on the outer surfaces of the first core body and the second core body. According to the invention, the insulating layer in the insulating sleeve is not easy to explode after being broken down, so that the fault probability of the insulating sleeve is reduced.

Description

technical field [0001] The present application relates to the technical field of insulating bushings, in particular to a capacitive voltage equalization system for the main insulation of glue-impregnated fiber bushings. Background technique [0002] At present, in the construction process of transformers and power distribution cabinets, insulating bushings are required to ensure safe operation of transformers or power distribution cabinets. Now common insulating bushings include oil insulating bushings and gas insulating bushings. [0003] In related technologies, insulating bushings mainly use insulating oil or gas as the main inner insulation, but it is prone to aging of insulating oil or gas leakage, such as leakage of sulfur hexafluoride gas, which leads to easy breakdown of the insulating layer and even explosion. cause the bushing to fail. [0004] Therefore, there is an urgent need for a capacitive voltage equalization system for the main insulation of the rubber-imp...
