Title:
SYSTEM FOR MONITORING ACCELERATED DEGRADATION OF HVDC POWER CABLE
Document Type and Number:
WIPO Patent Application WO/2024/090638
Kind Code:
A1
Abstract:
The present invention relates to a system for monitoring accelerated degradation of a HVDC power cable, the system comprising: a cable holding module formed by winding a cable degradation portion of a test cable around an insulated cylinder formed on the secondary side of an iron core, and by winding a primary-side coil around the primary side of the iron core; a DC high-voltage application module for applying electric stress to the test cable; a degradation power supply portion for generating an induced current that applies thermal stress to the test cable; a first ground line connected to an insulator portion of the test cable such that same is grounded; a second ground line connected to an external semiconductive layer of the test cable such that same is grounded; an ammeter formed on the second ground line to measure currents; a control module for controlling the entire device; and an accelerated degradation monitoring module for collecting/processing/computing information of the ammeter and the DC high-voltage application module, thereby computing and outputting conduction currents. The present invention advantageously provides a system for monitoring accelerated degradation of a HVDC power cable, wherein the conduction current of a test cable is measured while degrading the test cable in a specific condition, thereby determining whether the cable is degraded or not, such that the time of production of the test sample can be known, and equipment necessary for sample production is simplified, thereby reducing device costs and efforts.
