Title:
NON-INVASIVE HIGH-VOLTAGE POWER TRANSMISSION CABLE ONLINE AUTOMATIC MAINTENANCE AND DEFECT REPAIR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/024924
Kind Code:
A1
Abstract:
A non-invasive high-voltage power transmission cable online automatic maintenance and defect repair system. The system comprises: a high-voltage power transmission cable (101) having a polypropylene-iron oxide nanocomposite material as an insulation material; and multiple non-invasive high-frequency current excitation devices (102, 103, . . . , 10N). The multiple non-invasive high-frequency current excitation devices are arranged at an equal distance therebetween, and each non-invasive high-frequency current excitation device surrounds the high-voltage power transmission cable, and is configured to non-invasively inject a high-frequency current into the high-voltage power transmission cable, and to automatically realize magnetic heating and heat insulation of the polypropylene-iron oxide nanocomposite material, so as to autonomously repair an initial electrical tree defect in the insulation material. The system can increase the service life of a power transmission cable, reduce a failure rate of a power transmission system and improve the reliability of the power transmission system.
