Opening speed detection based on displacement sensor

The speed of the vacuum switch opening and closing speed indicates the speed of the vacuum switch opening and closing process as a whole. Its size can directly affect the recovery strength of the medium after the arc and the degree of opening and closing bounce. This paper mainly introduces a method for detecting the opening speed using a linear displacement sensor. This method can successfully detect the opening speed of the vacuum switch, which lays a technical foundation for the study of the mechanical parameters of the vacuum switch.
