【Abstract】 The influence of copper foil surface quality on electrical performance of power transformer is analyzed, the key technology for monitoring the surface flaw with machine vision system is studied. Monitoring device has been developed to find the surface flaw and alarm all at once, which can give information of property, position, numbers and size of the flaw. The test on copper foil in winding shows the monitoring method is effective, and the device can find flaws such as burr, nick, and pinhole.更多还原
