Method for collecting mechanical characteristic parameters of breaker based on high-speed camera

Abstract

A method for collecting the mechanical characteristic parameters of a breaker based on a high-speed camera comprises the following steps that (A) the high-speed camera (1) is used for capturing the image information of an operation mechanism (2) during moving in the closing and opening process of the breaker, wherein the operation mechanism (2) comprises a switching-on spring (3), a spindle (4), a metal connecting rod (5), a main connecting lever (6) and a switching-off spring (7); (B) the collected image information is input into an industrial personnel computer, images are analyzed and processed, and all the mechanical characteristic parameter values of the breaker are calculated; (C) conventional electric signals and vibration signals are fused in the mechanical characteristic parameter values obtained by processing of the images, and sound wave signals are combined for conducting analysis to obtain comprehensive and reliable mechanical characteristic parameter values. The parameter test precision and the speed calculated by the method are both greatly improved, a non-contact type measuring method is achieved, and the problem that sensor clamps for mounting different breakers are not universal on the site is solved.
