Abstract
The utility model relates to a bypass conversion device, especially to an online bypass conversion device which is convenient for detecting faults of electric devices. The bypass conversion device is used in a voltage stabilizer and a voltage regulator and main comprises an electric device and a series winding, wherein one side of the electric device is provided with an input end and the other side is equipped with an output end, and one end of the series winding is connected to the input end and the other end is connected to the output end. The bypass conversion device is characterized in that the input end is connected with a common winding and a change-over switch is arranged in the middle of the common winding. With the design by which the change-over switch is arranged between the input end of the electric device and the common winding, when the electric device goes wrong, the change-over switch of the common winding is off and converts to the other end so as to short out the common winding such that voltage at the input end is transferred to the output end directly through the series winding so as to be outputted to other equipment. Therefore, induced voltages which cancel or increase each other will not generated in the electric device such that voltage is outputted for continuous power supply. Faults of the electric device can be rapidly detected and maintained, and cost is also reduced.
