| titleOfInvention | A device and method for judging and diagnosing the switching state of a high-voltage isolating switch |
| abstract | The invention discloses a device and a method for judging and diagnosing the switching state of a high-voltage isolation switch. The method firstly uses a camera to shoot a video image of the switching state of a high-voltage isolation switch, and then adopts a method based on the directional gradient histogram HOG and the SVM support vector machine. Identify a group of high-voltage disconnector opening and closing original video images; then use Canny algorithm and Hough transform to obtain the straight line shape of the outer contour of the high-voltage arm; then first determine whether the image to be detected contains a specific type of high-voltage disconnector, and then according to the high-voltage The opening and closing state of the high-voltage isolation switch is judged by the relationship between the angle between the outer contour of the arm and the opening in-position determination angle N2 and the closing in-position determination angle N1. The invention does not need to accurately model the motion of the high-voltage isolation switch, is not limited to a specific type of isolation switch, and has wide applicability; strong target tracking ability, stability and reliability, outstanding anti-interference ability, and can be widely adapted to various on-site environments. |
