High voltage circuit breaker switch-on and switch-off speed characteristic measurement method based on machine vision
ActiveCN106526467AMeet online monitoringAvoid Closing Speed EffectsCircuit interrupters testingMoving partsLinear motion
The present invention provides a high voltage circuit breaker switch-on and switch-off speed characteristic measurement method based on machine vision. While the motion of a high voltage circuit breaker is recorded, a high speed camera is used to shoot the color mark of the surface of an observed moving part, a recorded video image is processed and identified through a machine vision algorithm, the position coordinate of the observed object of each frame of image of a video relative to a reference point is determined, the movement track of the observed object is obtained, and thus the switch-on and switch-off speeds of a high voltage circuit breaker moving contact are calculated. The installation of a sensor in a mechanical mode is not needed, only the setting of a color reference mark at an observation point is needed, a sensor is not need to replace for different measurement objects, and only the change of the position of a reference mark is needed. In addition, the linear motion or rotation speed can be measured, the field application is facilitated, the influence of an environmental condition of the equipment is small, and the need of online measurement of power switch equipment such as a high voltage circuit breaker in a live operation can be satisfied.
