Abstract: In allusion to a burning accident of voltage reacting plug-in. this paper analyzed the accidental causes. The voltage switching box was inspected, as well as the device of voltage reacting and paralleling. This paper analyzed the causes of potential transformer’s secondary winding anti-inverse charging and expounded the principles of voltage switching circuit, voltage reacting and paralleling circuit, pointing out that the ultimate cause of the accident was the potential transformer’s secondary winding anti-inverse charging. Combined with the actual work, this paper presented various kinds of precautions to prevent the similar accidents.
Key words: voltage switching; voltage reacting; anti-inverse charging; precautions
