Description

technical field [0001] The invention belongs to the field of electrical performance evaluation and fault diagnosis of insulating oil for ultra-ultra-high voltage oil-paper insulating electrical equipment, and relates to a measurement system and a measurement method for the motion characteristics of impurity particles in insulating oil. Background technique [0002] During the operation of UHV oil-paper insulation electrical equipment, the insulating oil is inevitably polluted by impurity particles, which seriously affects the electrical performance of the insulating oil and the safe operation of the equipment. Studies have shown that metal impurities such as copper filings and iron filings and non-metallic impurities such as fibers and dust are easily mixed into the insulating oil during the manufacturing and assembly of transformers, and are also likely to remain during the manufacturing and assembly of oil tanks and pipelines. Impurity particles contaminate insulating oil....

Problems solved by technology

[0005] The design of EHV / UHV converter transformers generally adopts uniform electric field or slightly uneven electric field. The existing research on the motion characteristics of fiber particles in transformer oil is mainly based on the slightly uneven electric field of the ball-ball electrode and the extremely uneven electric field of the pin-plate electrode. , has not been studied for the uniform electric field, and the motion characteristics of fiber particles in oil in the transition region between uniform and non-uniform electric fields

On the other hand, scholars at home and abroad have not studied the movement characteristics of impurity particles in insulating oil at different temperatures according to the operating temperature of the equipment
