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 insul

Abstract

The invention discloses a method of improving the insulation performance of a chip resistor unit. Resistor strips or resistor chips are arranged together, adjacent resistor strips or resistor chips are isolated by an insulation material, an integral insulation tube is adopted to isolate the adjacent resistor strips or resistor chips, and through the integral insulation tube, isolation, insulation and positioning are carried out between adjacent resistor strips or resistor chips. Clamping grooves are opened in the integral insulation tube, all resistor strips or resistor chips are clamped in the clamping grooves in the integral insulation tube, and through the clamping grooves, isolation, insulation and positioning are formed among the resistor strips or resistor chips. The resistor strips or resistor chips are clamped through the integral insulation tube. The resistor strips or resistor chips can be effectively positioned, insulation and isolation between the resistor strips or resistor chips can be effectively realized, the creepage distance of the resistor strips or resistor chips is greatly increased, problems such as moisture to affect the insulation performance do not happen, and the insulation performance of the resistor unit is improved.

Description

technical field [0001] The present invention relates to a structure of a resistor and an insulation method thereof, in particular to a method for improving the insulation performance between resistance bands or resistance plates of a chip resistor, which improves the resistance band or resistance of a chip resistor The method for the insulation performance between sheets can improve the insulation performance between resistance bands or resistance sheets in a resistor unit, and increase the creepage distance and withstand voltage value of the resistance bands or resistance sheets; it belongs to the technical field of chip resistor manufacturing. Background technique [0002] Chip resistor is a very widely used resistor. For example, on the current electric locomotive, in order to make the high-speed train or high-speed rail brake at a smooth speed, it is necessary to convert the kinetic energy and potential energy through the braking resistor. The generated electric energy i...
