Problems solved by technology

[0008] The purpose of the present invention is to solve the problem of shortening the creepage distance in the rainy environment by using a single porcelain piece for the insulation isolation between the porcelain piece and the resistance band or the resistance piece in the existing chip resistor, which affects the resistance unit in the rainy environment. The insulation performance cannot meet the high-voltage requirements in the rainy environment. A new type of isolation insulation method by resistance bands or resistance sheets is proposed, which can effectively solve the problem of isolation and insulation between resistance bands or resistance sheets. The isolated insulation has the problem of shortening the creepage distance in the rain environment, which can effectively improve the insulation performance of the resistance unit in the rain environment and meet the high voltage resistance requirements of the resistance unit in the rain environment

Abstract

The invention provides a method for implementing isolation insulation of resistance sheets by rotating an integral insulation tube, and a resistance unit. The integral insulation tube passes through resistance tapes or resistance sheets which are combined and arranged together, and then is rotated, so that necks on the integral insulation tube clamps the resistance tapes or the resistance sheets,and accordingly isolation insulation and positioning of the resistance tapes or the resistance sheets are realized through the integral insulation tube. The necks are formed in the integral insulationtube, the integral insulation tube passes through all resistance tapes or resistance sheets, then the integral insulation tube is rotated, so that the neck on the integral insulation tube clamps theresistance tapes or the resistance sheets, and isolation insulation and positioning are formed between the resistance tapes or the resistance sheets through the necks. According to the method providedby the invention, the integral insulation tube is rotated in mounting holes of the resistance tapes or the resistance sheets to clamp the resistance tapes or the resistance sheets, so that the resistance tapes or the resistance sheets can be effectively positioned, and the insulation isolation of the resistance tapes or the resistance sheets can also be effectively realized, the creep distances of the resistance tapes or the resistance sheets are increased, and the insulation performance of a resistor is improved.
