Abstract

An electric apparatus dynamic testing device which adopts a high-speed camera and comprises a CCD camera head (F) of the high-speed camera, a host (I) of the high-speed camera, a signal acquisition and control circuit (K), a computer (J), a voltage sensor (A), a current sensor (B), an action mechanism (D) of an electric apparatus to be measured, a contact system (C) of the electric apparatus to be measured and a contact action signal circuit (E); the electric apparatus dynamic testing device realizes the test of the dynamic process and the characteristics of the electric apparatus by shooting and processing motion displacement images of the action mechanism of the electric apparatus.

Description

technical field [0001] The invention relates to a dynamic testing device for electrical appliances using a high-speed camera, which belongs to the technical field of testing high-voltage and low-voltage switching electrical appliances. Background technique [0002] Miao Xiren, Zhang Peiming, etc. published the article "Development of Dynamic Test Device for Optical Electromechanical Electromagnetic Appliances" in the fourth issue of "New Technology of Electrical Engineering and Electric Energy" in 2001. It is introduced that thin slices are embedded on the skeleton of the movable parts of the electromagnetic system, and the laser parallel light source is used. The movement of the movable part is converted into a beam of moving parallel light, and a high-speed linear array CCD is used to convert the moving beam into light-receiving pixels that move rapidly along the line array, and the CCD will output video signals that change with the movement of the movable part for electrom...
