Transformer bushing capable of removing dirt when encountering water

Abstract

The invention discloses a transformer bushing capable of removing dirt when encountering water, and belongs to the field of transformer insulating bushings. The transformer bushing comprises a tubular column and a plurality of porcelain plates, wherein the porcelain plates are evenly and fixedly connected to the outer end of the tubular column. Through the arrangement of the accumulated water trigger ring, rapid collection of rainwater in rainy days can be realized; the hard water filtering net is triggered to be driven through accumulation of rainwater, so the hard water filtering net drives the cotton thread net and the multi-section washing assisting soft rod to approach the porcelain dish, and deep cleaning of dust on the surface of the porcelain dish is achieved along with rotating motion; meanwhile, in combination with flowing of rainwater on the surface of the porcelain plate, the surface of the porcelain plate is quickly recovered to be clean; moreover, after the single triggering is completed, the accumulated water triggering ring water loss is recovered to the original position, and the triggering process is continued again. Therefore, dust on the surface of the porcelain plate can be deeply and effectively removed, the cleanliness of the porcelain plate is recovered, and flashover accidents of the porcelain plate are reduced.

Description

technical field [0001] The invention relates to the field of transformer insulating bushings, more specifically, to a transformer bushing of water-removing pollution type. Background technique [0002] The transformer bushing is the main insulation device outside the transformer box. The lead-out wire of the transformer winding must pass through the insulating bushing to insulate between the lead-out wires and between the lead-out wire and the transformer shell, and at the same time play the role of fixing the lead-out wire. Due to different voltage levels, insulating bushings are available in the form of pure porcelain bushings, oil-filled bushings and capacitor bushings. Pure porcelain bushings are mostly used in transformers of 10kV and below. It is a conductive copper rod inserted in the porcelain bushing, and the inside of the porcelain bushing is air-insulated; oil-filled bushings are mostly used in 35kV transformers. It is filled with oil in the porcelain bushing , p...

AI Technical Summary

Problems solved by technology

[0003] Due to the long-term exposure of the transformer insulating bushing to the air, a large amount of dust and pollution are easily accumulated on its surface, and the insulation strength of the bushing surface will be reduced in rainy days. Flashover accidents are prone to occur
