More Information
Summary:The invention provides a loaded capacitance-adjustable serial multibreak switch by a series-parallel connection method, which solves a problem that a loaded capacitance-adjustable switch disclosed by CN200910187320.1 is used for a transformer with star angle conversion on the high voltage side of the transformer and series-parallel connection on the low voltage side of the transformer, and the variable capacitance ratio of the transformer is 0.33. The invention is mainly characterized in that when two adjacent windings are connected in parallel in the switch, the parallel line consists of a plurality of moveable and stationary contacts connected in series to form a serial multibreak. The invention has the positive effects that the series-parallel connection method can be applied to the high voltage side of the transformer, and the variable capacitance ratio can be randomly adjusted within 0.25 and 1 so that the capacitance-adjustable transformer is more agilely applied to various load conditions.
