Problems solved by technology
[0002] The high-voltage line will inevitably be damaged during transportation, installation and long-term operation. When the high-voltage line is transmitting power, a strong electric field will be formed around the damaged high-voltage line, which will ionize the air and form a corona discharge, resulting in a large amount of power loss. Traditional In the technology, there is no better device for positioning and repairing the corona discharge of high-voltage cables. If a large number of high-voltage cables are replaced, the cost is high and it is impractical

The invention discloses a high voltage cable repair device and relates to the high voltage cable repair technology field. The device comprises an upper shell and a lower shell. A fixing sleeve is fixedly connected between the upper shell and the lower shell, and a cable repair component is arranged in the fixing sleeve. Openings are axially arranged on the cable repair component and the fixing sleeve, and the cable repair component is connected to a driving mechanism which is axially rotated by a driver. Through conversion of liquid-solid phases of electrorheological fluid under a high electric field, positioning of a cable breakage portion is realized, and the cable repair component is cooperated to repair the cable breakage portion. Corona discharge at the cable breakage portion is usedto achieve the positioning, which is more targeted, and a problem that the cable cannot be repaired in a targeted manner in a conventional technology is solved.
Description
technical field [0001] The invention relates to the technical field of high-voltage cable repair, in particular to a high-voltage cable repair device. Background technique [0002] The high-voltage line will inevitably be damaged during transportation, installation and long-term operation. When the high-voltage line is transmitting power, a strong electric field will be formed around the damaged high-voltage line, which will ionize the air and form a corona discharge, resulting in a large amount of power loss. Traditional In the technology, there is no better device for positioning and repairing the corona discharge of high-voltage cables. If a large number of high-voltage cables are replaced, the cost is high and it is impractical. Contents of the invention [0003] The object of the present invention is to solve the above problems, and propose a high-voltage cable repair device. [0004] In order to achieve the above object, the present invention adopts the following te...
