OIL FLOW OVERFLOW FAULT DETECTION METHOD AND SAMPLER FOR OIL-FILLED HIGH-PRESSURE CASING

摘要

An oil flow overflow fault detection method for an oil-filled high-pressure casing, which performs unsaturated carbon-carbon bond detection by means of a chemical reaction, and determines whether an oil flow overflow fault occurs in the oil-filled high-pressure casing by means of the detection result of the unsaturated carbon-carbon bond. Specifically, a bromine carbon tetrachloride solution or a potassium permanganate aqueous ethanol solution is used as a detection reagent to detect a sample that is sampled from a surface of an oil-filled high-pressure casing to be tested, and it is determined whether the unsaturated carbon-carbon bond is detected according to whether a detection test paper is discolored, thereby determining whether an oil flow overflow fault has occurred in the oil-filled high-pressure casing to be tested. The present invention further relates to an oil flow overflow fault detection sampler for an oil-filled high-pressure casing, comprising a support rod (1), a sampling brush (3), and a fixing member (2) that is used for rotatably fixing the sampling brush and that is mounted at a top end of the support rod. The detection method and the sampler are simple and easy to operate, are resistant to environmental interference, and have the characteristics of accurate, sensitive and prompt detection.
