A Study On Temperature Distribution of arc Cross Section of Low-Voltage Apparatus

In this paper, a set of hardware instruments used to collect arc radiant intensity in three directions were designed by using single area CCD based on high temperature characteristic of low-voltage apparatus switch arc, and the principle of computer tomogram and corresponding image processing software was also developed. We took pictures for the projection of breaking arc radiation of the low-voltage AC contactor in inductance circuits, and rebuilt its temperature distribution on different sections when burning.
