Problems solved by technology
However, the above-mentioned withstand voltage testers can only complete the withstand voltage test of the electrical film at room temperature, but cannot complete the test of the withstand voltage performance of the electrical film at high temperature; in addition, according to the requirements of the test process, each sample needs to test more than 5 points. Still need to open the safety door frequently to change test points

The invention relates to an electrical thin film high temperature withstand voltage tester, comprising a test part and an electric control part, the test part includes a fixed electrode, a movable electrode and an insulating support, the test part is arranged in an oven, and the insulating support includes an upper and a lower support, The movable electrode is fixed on the lower end of the metal conductive shaft through the metal rotating arm, the middle of the upper bracket is provided with a metal sleeve for circumferentially positioning the conductive shaft, the upper end of the conductive shaft is fixed with an insulating rod, and the middle position of the top of the oven is provided with a passage for the insulating rod to pass through. The top of the insulating rod is fixed with a rotating handle, and the bottom of the oven is provided with a through hole for the test lead to pass through. The oven is used as the pressure test room, which can test the pressure resistance performance at high temperature; and it can be continuously tested without opening the pressure test room, that is, the oven door, which can improve the test efficiency.
Description
technical field [0001] The invention relates to an electrical thin film withstand voltage tester, in particular to an electrical thin film high temperature withstand voltage tester. Background technique [0002] 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 Pressure tester. The test part includes a pair of test electrodes and an insulating support, one of which is a fixed electrode and the other is a movable electrode. The test part usually has an insulation test room. Since each test needs to detect multiple points, it is necessary to open the test room to replace the test points after the test. In order to facilitate the replacement of test points, the withstand voltage test chamber of the electrical film withstand volt...
