Description

technical field [0001] The invention relates to a three-dimensional dynamic testing device for an intelligent AC contactor based on monocular vision technology, which belongs to the technical field of high and low voltage switching electrical appliances testing. 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 th...

AI Technical Summary

Problems solved by technology

The test device can only test the two-dimensional dynamic characteristics of the intelligent AC contactor, but cannot complete the test of the three-dimensional dynamic characteristics

[0003] Sliding resistance type and differential measurement are contact measurement. Clinging to the intelligent AC contactor will affect the dynamic process of the contactor (at the same time, the movement of the intelligent AC contactor will also affect the sensor), thus affecting the measurement accuracy and accuracy

If it is necessary to measure motion parameters in three directions, three sensors are required, and it is difficult to achieve synchronous control during control
