OIL LEAKAGE DETECTION METHOD OF OIL IMMERSION INSULATING POWER CABLE, STRING-LIKE BODY FOR OIL LEAKAGE DETECTION OF OIL IMMERSION INSULATING POWER CABLE, AND POWER TRANSMISSION SYSTEM

摘要

To provide an oil leakage detection method of an oil immersion insulating power cable capable of accurately detecting oil leakage even when oil leakage from the oil immersion insulating power cable is very small, and to provide a string-like body for oil leakage detection of oil immersion insulating power cable, and a power transmission system.SOLUTION: An oil leakage detection method of an oil immersion insulating power cable 11 pulls a string body 1, installed parallel to the oil immersion insulating power cable 11, in a longitudinal direction and collect it into a lower side of the oil immersion insulating power cable 11, and detects whether oil leakage occurs on the basis of whether oil is absorbed in the string-like body 1.SELECTED DRAWING: Figure 1
