A sound source device is installed on the movable contact, and a sound detection device is installed near the fixed contact and in the vicinity of the open circuit position of the movable contact, and according to the movement of the movable contact, the sound source observed by the sound detection device is Utilizing the fact that the frequency changes due to the Doppler effect, the sound detection device outputs a frequency modulated wave corresponding to the opening/closing speed, and after cutting the part corresponding to the amplitude modulation, the amplitude is modulated and then DC conversion is performed. A circuit breaker opening/closing speed measuring device comprising: a device that calculates the opening/closing speed from the voltage difference between the two and displays it on a meter as the opening/closing speed.
