Problems solved by technology

The existing electrical film withstand voltage tester often has large differences in withstand voltage values ​​of the same specifications of electrical films produced on different production days, and the gap between the maximum and minimum withstand voltage values ​​of electrical films of the same specification produced on the same production day is large, resulting in test data No, the data is distorted
The reasons are as follows: 1. Improper collection and handling of thin film samples, resulting in increased accidental errors; 2. The membrane surface was damaged during the collection of sample membranes; 3. The upper and lower electrodes were in rigid contact during the test process, which damaged the membrane surface; 4. The test electrodes If the cleaning is not timely, membrane scale will accumulate on the electrode; 5. The amount of test data is small, resulting in scattered test data

Abstract

The invention relates to a test method of an electrician's film withstand voltage tester, involving a sampling tool to sample a sample film and a test tool to test the sample film. The sampling tool comprises workbench (6), sampling template (3), sampling pad (2) and utility knife (5); the test tool comprises upper electrode (9), lower electrode (10), flexible rubber block (8) and aluminum foil (7). The test method has small accidental errors; film surface is never damaged during sample film acquiring and testing; more test data are provided; the test data are more authentic.

Description

technical field [0001] The invention relates to an electrical film withstand voltage tester, in particular to a testing method for an electrical thin film withstand voltage tester. Background technique [0002] With the improvement of users' requirements for the quality of electrical film, all electrical film manufacturers adopt quality tracking control in the production process in order to achieve the purpose of improving their quality. Hi-pot test, while recording test data for analysis by technicians. The electrical film withstand voltage tester is an instrument used to perform a withstand voltage test on an electrical film, and generally consists of a testing part located above the workbench and an electrical control part located below the workbench. CN201489083U discloses such an electrical film Withstanding voltage tester, the test part includes a pair of test electrodes and insulating brackets, one of which is a fixed electrode and the other is a movable electrode. T...
