Description

technical field [0001] The present disclosure relates to the related technical field of electric high-voltage cable equipment, and in particular, relates to a built-in insulating oil intelligent purification device and method, and a high-voltage cable oil-filled terminal. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] During the normal operation of the high-voltage cable oil-filled terminal, it is necessary to strictly maintain airtight and sealed operation for a long time. During operation, any behavior that damages the seal is strictly prohibited. The insulating oil filled inside the high-voltage cable oil-filled terminal can insulate, infiltrate, and cool the high-voltage cable. The role of the internal components of the oil-filled terminal, the quality of the insulating oil plays a vital role in ensuring the safe operation of high-v...

AI Technical Summary

Problems solved by technology

Although the insulating oil initially filled into the oil-filled terminal of the high-voltage cable can maintain excellent physical and chemical properties and electrical properties, the insulating oil will naturally age during long-term operation, and if abnormal heating and discharge of the oil-filled terminal of the high-voltage cable occur during operation, It will cause cracking of the insulating oil, and the related components of the cable oil-filled terminal will precipitate decomposition products due to poor manufacturing quality, which will also pollute the insulating oil. Once accumulated to a certain extent, it will directly endanger the safe operation of high-voltage cables, and even lead to vicious failures such as explosion and burning of cable terminals, seriously endangering the personal safety of surrounding personnel and the safe operation of the power grid.

[0004] During the normal operation of the oil-filled terminal of the high-voltage cable, it is required to keep it tightly sealed. Therefore, the oil-filled terminal of the high-voltage cable cannot be purified by external oil filtering equipment like the traditional oil-filled main transformer or oil-filled transformer. The internal insulating oil is purified. At present, there is no corresponding purification device in the high-voltage cable oil-filled terminal equipment. The quality of the insulating oil inside the high-voltage cable oil-filled terminal cannot be controlled. It can only be caused by a failure in the operation of the high-voltage cable oil-filled terminal. After replacement or maintenance, it will affect the normal operation of high-voltage cables, poor safety, and cause huge waste
