Problems solved by technology

The "mini" electrostatic test method is simple, easy to use, and accurate in measurement. It has been used in China, but it is all manual operation, which requires repeated manual sampling, manual pressure test, and manual reading of the test current data for calculation. The process is cumbersome and the efficiency is low. Low

Description

Technical field [0001] The invention provides an automatic detection device for the electrification degree of transformer oil, which belongs to the technical field of electrical measuring instruments. Background technique [0002] The safe operation of oil-filled power transformers is an important issue faced by power supply departments. Since the insulation performance of transformer oil is affected by many factors, such as moisture, impurities, temperature, and the electrification of the oil itself, in order to ensure the safe and stable operation of the transformer, it is necessary to detect its related indicators in real time. Among them, due to the friction between the transformer oil and the inner wall of the transformer and the internal insulating material, electric charges are generated, that is, the insulating oil is charged, which leads to the reduction of its insulation performance and affects the safe operation of the transformer, which has attracted more and mor...
