Abstract

The application relates to a method for judging the closing position of an isolating switch. The method for discriminating the closing position of the isolating switch divides the point cloud image of the isolating switch to be tested into a plurality of voxels, and selects a plurality of centers of gravity to be measured as feature points of the point cloud image of the isolating switch to be tested for calculation . The method for discriminating the closing position of the isolating switch avoids comparing and calculating all the data in the point cloud image of the isolating switch to be tested. The method for judging the closing position of the isolating switch requires less calculation data and a small amount of calculation, thereby improving the detection efficiency of the opening and closing state of the isolating switch.

Description

technical field [0001] The present application relates to the technical field of knife switch detection, and in particular, to a method for judging the closing position of an isolation switch. Background technique [0002] Isolation switches, also known as knife isolation switches, knife isolation switches, etc., are used in high-voltage equipment of various levels in substations and power stations to change circuit connections to connect or isolate lines or equipment from power sources. Usually, when overhauling equipment or replacing lines, in order to ensure the safety of maintenance personnel and equipment, it is necessary to separate the overhauled equipment or lines from the power supply with an obvious disconnection point, and the isolating switch is such a disconnection point. [0003] The isolation switch realizes the action of opening or closing by moving its moving arm to different positions. The opening or closing actions of the isolating switch are all controll...
