<p>A switching device for transformer is provided to supply a stable voltage to the secondary wiring according to voltage drop due to the load characteristic of the distribution line. A switching device having an interruptible power include a plurality of switching elements(110), a current circulator(120) for the multiple switch and controller. A switching element is operated by the external signal, and the current circulator for the multiple switches is electrically connected to a high current route of the switching elements. The current circulator for the multiple switches replaces the ON role of the switching elements in switching between the switching elements. The Controller is electrically connected with the current circulator for the switching elements and multiple switches. A signal is supplied to the switching elements according to controller is the voltage value, and switching elements are successively changed.</p> |
