Abstract

The invention relates to a low-voltage direct-current arc energy distribution visualization research method and device, and the method comprises the steps of collecting the information of an arc, setting a preprocessing process of the collected information, carrying out the filtering operation and equalization processing of the electric parameters and image information of the arc, enhancing the image contrast, and removing the interference; determining the peripheral boundary of the arc by using an edge detection algorithm in an image processing technology; realizing simplified operation of the arc form by applying binaryzation; and monitoring the change trend of the area and the perimeter of the arc in the gap in the diffusion process by combining a morphological calculation principle. The two-dimensional energy and form distribution characteristics of the arc in the horizontal projection direction are visualized in the on-off process of the switching device.

Description

technical field [0001] The invention relates to the technical field of direct current arc energy visualization research, in particular to a low-voltage direct current arc energy distribution visualization research method and device. Background technique [0002] As an important device for control loop closure, low-voltage electrical appliances are widely used in the fields of distributed energy storage, ship propulsion, high-speed rail and electric vehicles, and are developing towards higher voltage levels. Low-voltage electrical appliances will generate high-temperature arcs in the process of closing and breaking, with huge energy. The arcs will have a strong ablation effect on the contacts and the space of the arc extinguishing chamber, which will seriously reduce the life of switching appliances. The distribution of arc energy directly affects the performance of switching appliances. work performance. With the advancement of computer and sensor technology, visualization ...
