Abstract

Aiming at the problem that the meshing distance of tulips contacts of circuit breakers cannot be measured

a method to calculate the tulip contacts’ meshing distance of circuit breakers which was suitable for different concentricity of the tulip contacts based on the operating data of driving motor of chassis car was proposed.First

the influence of concentricity of tulip contacts on the meshing distance was analyzed.Secondly

the essential points to calculate the meshing distance was described in detail

including the calculation of meshing distance by using equivalent meshing point on the current curve and employing support vector machine algorithm to locate the equivalent meshing point.In order to make the model meet the requirements of positioning equivalent meshing point under different concentricity

the samples of meshing-beginning stage were reconstructed.The eigenvector which could indicate the position of the equivalent meshing points and the concentricity was constructed.Finally

new data was sampled to examine the method.The results show that the accuracy of the algorithm was good under different concentricity and it could provide with a new idea to measure the meshing distance of contacts.
