A method for identification and damage detection of insulator flange shape parameters

Abstract

The invention discloses an insulator flange shape parameter identification and damage detection method, which is specifically as follows: Step 1: Adjust the installation position and shooting angle of the camera according to the position of the insulator string; perform histogram equalization and segmentation on the collected on-site insulator images , filtering, and connected domain marking processing, and finally get the flange area of ​​the insulator; Step 2: By analyzing the features of the intact flange and the defective flange of the insulator in the image, extract the circumference C, area A, and relative center distance d of the flange area The four shape features of , circularity e are used as the characteristic parameters of flange defect detection, and further determine whether the insulator is damaged; Step 3: Construct the insulator flange damage detection model, and take the four characteristic parameters obtained in step 2 as input, and the convex The intact / defective edge is used as the output, the model is trained and tested, and finally the detection and identification of insulator flange damage is realized. The method can realize non-contact and on-line monitoring of insulator flange damage.

Description

technical field [0001] The invention belongs to the technical field of image processing of power transmission lines, and in particular relates to a method for identifying and destroying shape parameters of an insulator flange. Background technique [0002] With the rapid development of the economy, the demand for electricity has gradually increased. High-voltage and ultra-high-voltage overhead power lines have become the main way of long-distance power transmission and distribution. Its safe and stable operation is an important guarantee for my country's economic construction. Insulators play an important role in high-voltage transmission lines: one is to provide mechanical support for the conductors that transmit current, and the other is to prevent the current from forming a channel grounding to the ground. Its working state is directly related to the normal operation of the entire power system. During operation, the insulator not only bears the action of working voltage a...

Problems solved by technology

However, the current flange damage mainly relies on manual detection, which has problems such as poor safety, time-consuming and labor-consuming, so it is urgent to propose an intelligent detection technology for insulator flange defects
