Abstract

The invention discloses a composite insulator hydrophobicity detection method and device, a medium and equipment, and the method comprises the steps: obtaining training samples, obtaining the hydrophobicity levels of the training samples through a water spraying classification method, and collecting images of all training samples after water spraying as training sample images; extracting a featurevector for the training sample image, and training a neural network model through the training sample to obtain a hydrophobicity detection model; for the composite insulator to be subjected to hydrophobicity detection, collecting an image of the composite insulator subjected to hydrophobicity detection after water spraying, and taking the image as a test sample image; and extracting a feature vector from the test sample image, and then inputting the feature vector into a hydrophobicity detection model to detect a corresponding hydrophobicity level. The composite insulator is hydrophobic, theinfluence of artificial subjective factors can be eliminated, and the hydrophobic grade detection accuracy is improved; meanwhile, the operation is simple, and artificial pollution caused by an existing test method can be avoided.

Description

technical field [0001] The invention belongs to the field of performance detection of power transmission line equipment, in particular to a method, device, medium and equipment for testing the hydrophobicity of composite insulators. Background technique [0002] An insulator is a device installed between conductors at different potentials or between conductors and grounding components that can withstand voltage and mechanical stress. It is a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with a lot of disc-shaped insulators hanging on one end, which is to increase the creepage distance. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the serv...
