Problems solved by technology

Due to the long time for replacing the silicone tank of the respirator, the heavy gas relay and the respirator cannot protect the main transformer during this period. The main transformer is damaged
At the same time, during the time of replacing the silica gel of the respirator, the surrounding humid gas directly enters the inside of the transformer without the respirator, causing the transformer oil to be damp and the insulation of the oil to be reduced. Will lose the insulation and lead to the scrapping of the main transformer or other grid accidents

Embodiment 1

[0051] Embodiment 1: a kind of method of building classifier identification model, comprises the following steps:

[0052] Obtain a training image sample, the pixel color in the training image sample includes a positive example color and a negative example color, the positive example color belongs to the first color gamut, the negative example color belongs to the second color gamut, the first color gamut and the second color gamut The intersection of domains is empty. Considering that the pure color color comparison card is used as a training image sample, there is a big gap between its application environment and the classifier recognition model. The color will also change color in different lighting environments, and there are too many uncontrollable factors. In this embodiment, real pictures are used as training sample images. For example, you can search for "blue picture" in a search engine, and use the color in the non-solid color picture that is mainly blue as the cou...

Abstract

The invention discloses a transformer respirator detection method, a classification model construction method, a computer readable medium storing a transformer respirator detection program and a transformer respirator monitoring system, and belongs to the field of transformer detection. At least five characteristics of hue, saturation and brightness in an HSV color space, blue concentration offsetand red concentration offset in a YCbCr color space and the like are associated with non-failed colors and failed colors of the transformer respirator, so that the available state of the transformerrespirator is detected.

Description

technical field [0001] The invention relates to the technical field of transformer respirator maintenance, in particular to a transformer respirator detection method, a method for constructing a classifier identification model, a computer-readable medium storing a transformer respirator detection program, and a transformer respirator device monitoring system. Background technique [0002] Respirator, also known as moisture absorber, is an auxiliary safety protection device of the main transformer and is widely used in power systems. The weather in the south is humid, and the silica gel adsorbent in the respirator fails frequently. Therefore, for the main transformer, replacing the silicone rubber of the respirator is a regular maintenance work. The traditional respirator silicone tank needs to be removed from the heavy gas protection of the main transformer before replacement, and the heavy gas protection should be turned on again after the replacement is completed. Due t...
