Abstract

The invention discloses a circuit breaker moving contact motion characteristic measurement method based on deep learning, and the method specifically comprises the following steps: S1, setting an auxiliary marker, and collecting a high-speed image sequence; s2, inputting the high-speed image sequence into the trained deep learning model, and tracking the motion trail of the auxiliary marker; and S3, calculating the travel time curve of the moving contact of the circuit breaker according to the track of the auxiliary marker. According to the circuit breaker moving contact motion characteristic measurement method based on deep learning, non-contact measurement is adopted, and a component which moves synchronously with the circuit breaker moving contact is tracked to measure the motion characteristic of the circuit breaker moving contact, so that the problems of target size change, background color interference and camera shaking can be effectively solved; and accurate tracking is realized.

Description

technical field [0001] The invention relates to the technical field of circuit breaker moving contact detection, in particular to a method for measuring the motion characteristics of a circuit breaker moving contact based on deep learning. Background technique [0002] In the power system, the high-voltage circuit breaker is very important. Once it fails, it may cause hidden dangers in the operation of the power grid and even threaten the life safety of the relevant personnel. The reliability assessment of high-voltage circuit breakers by the International Conference on Large Power Grids shows that 64.8% of the main faults of circuit breakers are operating mechanical faults. Measuring the motion characteristic parameters of the moving contact of the circuit breaker can evaluate the operating performance of the circuit breaker, which is an important technical means to detect the mechanical failure of the circuit breaker. [0003] At present, most of the mature measurement to...
