Abstract

The invention discloses a transformer oil leak detection method comprising the following steps: S1, acquiring the image information of a detection area of a transformer before oil leak; and S2, acquiring the current image information of the detection area of the transformer, comparing and processing the image information before oil leak and the current image information to get the oil leak direction information of the detection area and the color information of the detection area, and judging whether the detection area leaks oil based on the oil leak direction information of the detection area and the color information of the detection area to get a detection result. The transformer oil leak detection method has the technical effects of high detection efficiency and high detection accuracy.

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...
