Abstract

The invention discloses a transformer oil leakage detection method. The method comprises: S1: acquiring image information of a transformer detection area when no oil leakage occurs; S2: acquiring current image information of a transformer detection area, and combining the image information when no oil leakage occurs with Compare and process the current image information to obtain the oil leakage direction information of the detection area and the color information of the detection area, based on the oil leakage direction information of the detection area and the color information of the detection area, judge whether the detection area is leaking oil, and obtain the judgment As a result, the technical effect of high detection efficiency and accuracy of the transformer oil leakage detection method is realized.

Description

technical field [0001] The invention relates to the field of electric equipment safety detection, in particular to a transformer oil leakage detection method. Background technique [0002] Oil leakage often occurs in transformers. If the transformer oil level is within the specified range, it can still continue to operate or arrange planned maintenance. However, serious transformer oil leakage will affect the service life of the transformer. In addition, the oil level of the transformer oil is too low, so that the bushing leads and the tap changer are exposed to the air, and the insulation level will be greatly reduced, so it is easy to cause breakdown discharge and cause major accidents. [0003] In unattended substations, power transformers are commonly used and main equipment, and their operating conditions must be monitored in a timely manner. When abnormal conditions occur, corresponding alarms should be given. In the prior art, by detecting the gas components in the t...
