Corona-resistant clamp device and method

Abstract

The invention discloses a corona-resistant clamp device and a method. The corona-resistant clamp device comprises a supporting plate; sliding chutes are formed in the supporting plate, and supportinglegs are arranged in the sliding chutes; rolling wheels are arranged at the bottom of the supporting legs, and sliding rails are arranged outside the rolling wheels; the top of the supporting plate isprovided with a fixing plate, and the top and the bottom of the fixing plate are each provided with a placing frame correspondingly. According to the corona-resistant clamp device and the method, friction force can be reduced by arranging the sliding rails and the rolling wheels, so that the service life of the device is prolonged; clamping grooves can well fix materials, the working efficiency is reduced due to the shaking of the materials is prevented, and two materials can be placed at the same time for manufacturing in the clamping grooves, so that the working efficiency is greatly improved; handles are used by a first connecting rod and a second connecting rod of a pushing device, so that the force is reduced, and meanwhile, the operation can be carried out by one hand, then the useis more convenient, rubber anti-skid layers on the handles can increase the friction force, and hands of a user can be protected.

Description

technical field [0001] The invention relates to the field of corona-resistant fixtures, in particular to a corona-resistant fixture device and method. Background technique [0002] Corona-resistant polyimide film is the polymer material with the best comprehensive performance. With its technical advantages, it is widely used in household appliances (such as air conditioners, refrigerators), industrial production (such as machine tools, water pumps), wind power generation and rail transportation ( High-speed trains) and other fields. There is a big difference between the high-frequency high-voltage pulse square wave output by the insulated gate bipolar transistor (IGBT) and the power frequency sinusoidal voltage wave. In case of failure. Although polyimide film has been widely used in the electrical and electronic industry due to its excellent heat resistance, mechanical and dielectric properties, its life is greatly shortened under high-frequency pulse voltage, which canno...

AI Technical Summary

Problems solved by technology

Although polyimide film has been widely used in the electrical and electronic industry due to its excellent heat resistance, mechanical and dielectric properties, its life is greatly shortened under high-frequency pulse voltage, which cannot meet the requirements for use under variable frequency conditions.

The study found that the breakdown voltage of corona-resistant polyimide film is lower than that of ordinary polyimide film (100HN), but its life is greatly improved under high-frequency pulse voltage. The corona-resistant mechanism becomes A hot issue studied by scholars at home and abroad, the corona-resistant fixture is one of the important devices for the study of the corona-resistant mechanism. The existing corona-resistant fixture has a simple structure, is laborious to use, and has low efficiency.
