するしゃ断器の開閉速度測定装置。In a disconnector that is equipped with a fixed contact and a movable contact for disconnecting an electric circuit and is operated by fluid pressure, when measuring the speed at the time of opening or closing, the movable contact is provided with a sound source device number and a sound source device number of the fixed contact. A sound detection device is attached to each nearby, and according to the movement of the movable contact, the frequency of the sound source observed by the sound detection device changes due to the Doppler effect. The invention is characterized by being equipped with a device that outputs a frequency modulated wave, cuts a portion corresponding to the amplitude modulation, modulates the amplitude, calculates the opening/closing speed after DC conversion, and displays it. A device for measuring the opening and closing speed of circuit breakers.
