Improve the structure and enhance electrical low-voltage AC contactor

Research can improve the contact material, improve the structure and enhance electrical low-voltage AC contactor electrical performance to provide support. Firstly, the use of area array CCD camera based on low-voltage AC contactor switch arcing  electri cenergy meter image  electric transformer  system for low-voltage AC contactor switching arc to arc extinction from a series of images for the collection, and then use the adaptive  electric meter  algorithm collected from the low-voltage AC contactor arc images were de-noising and sharpening method Laplace edge of the image as well as the arc details were sharpening.
