Abstract

The invention relates to a fixing frame for withstand voltage partial discharge experiments of a dry type instrument transformer. The fixing frame comprises two stand columns, a panel and hold hoops. The stand columns are welded in an inverted-T-shaped mode through two steel tubes. The lower ends of the horizontal steel tubes are provided with two supporting legs. The panel is of a rectangular structure, and the lower portion of the panel is provided with a round bracket. Four holes corresponding to the hold hoops are formed above the bracket and connected with the two stand columns through a connecting shaft. The panel can rotate along the connecting shaft. A connecting pull rod with one end connected with the panel and the other end connected with the stand columns is arranged below the connecting shaft. A limiting screw is arranged below the pull rod. The hold hoops penetrate through the holes in the panel and are connected with the panel through the screw. The fixing frame provides a stable platform for the withstand voltage partial discharge experiments of the dry type instrument transformer.

Description

technical field [0001] The invention relates to a fixed frame for a dry-type transformer pressure-resistant partial discharge experiment. Background technique [0002] The measurement of partial discharge is an important item in the factory test of high-voltage transformers. The level of partial discharge directly affects the performance of transformer products. The electrons, ions and thermal effects generated by partial discharge will accelerate the electrical aging of product insulation and reduce The useful life of the product. Therefore, it is very important to understand the causes of partial discharge and its troubleshooting methods to ensure the product quality and performance of the transformer. The dry-type transformer has a "U"-shaped structure, which is not easy to fix in the test, which brings certain difficulties to the partial discharge test of the dry-type transformer. Contents of the invention [0003] The purpose of the present invention is to solve the...
