Positioning device for AC capacitor endurance test

Abstract

The invention relates to the technical field of AC capacitor endurance tests, and discloses a positioning device for an AC capacitor endurance test. The device comprises a pedestal, connecting platesare fixedly installed at the left and right sides of the top of the pedestal, sliding grooves are formed in the bottoms of the inner walls of the connecting plates, and sliding blocks are movably installed in the sliding grooves. According to the positioning device for the AC capacitor endurance test, by arranging clamping plates, when the endurance test needs to be carried out on the AC capacitor, the AC capacitor is firstly placed in the clamping grooves of the clamping plates on the two sides, and then the AC capacitor is clamped among the three clamping blocks; and when the AC capacitor isclamped, extension springs can be pushed towards the two sides, a distance between clamping rods on the two sides can be adjusted according to the length of the AC capacitor, meanwhile, the movable plate can be moved forwards and backwards, the movable plate drives the sliding rod to move forwards and backwards in the connecting plate, a positioning effect is achieved, and meanwhile the positioning device is more flexible.

Description

technical field [0001] The invention relates to the technical field of AC capacitor endurance test, in particular to a positioning device for AC capacitor endurance test. Background technique [0002] The durability test is a test to measure the service life of the product under specified conditions of use and maintenance, and to predict or verify the weak links and dangerous parts of the structure. The test time of the durability test is generally longer than that of the reliability test. Passing the durability test, Find out which parts have reliability problems in product design and manufacturing, so as to improve the design or improve the process level. At the same time, the service life of the new product can be calculated by measuring the wear and tear changes of the main parts. [0003] During the AC capacitor durability test, the AC capacitor needs to be fixed in the durability test box, but the traditional positioning device has a simple structure and cannot achieve...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a positioning device for AC capacitor durability test, which has the advantages of accurate positioning and convenient adjustment, and solves the problem that the traditional positioning device is simple in structure and cannot achieve accurate positioning. When the size of the AC capacitor is different, it is necessary to replace the positioning device of different specifications, and the process is more troublesome.
