| In recent years, with the rapid development of subway, and the rise of the HVDC project, China's electricity consumption increases, the DC breaker demand increases. Different from the ordinary circuit breaker, due to DC breaking no natural zero, so the domestic and foreign researchers generally use artificial zero-crossing method is the DC current in normal or fault on the high-frequency current superimposed a reverse to create zero, this method has become one of the research focus in the field of high voltage electrical apparatus. Solve the fundamental DC interruption is extinguished arc, so must understand the forms and characteristics of arc quenching process, the digital image processing technology has matured to become possible, using high-speed camera to record the arc interrupting process and analysis and sums up the characteristics of DC arc. |
