Abstract
PURPOSE: To prevent a short circuit of a direct current power source and to duplicate a direct current to an alternating current without disconnecting a grounding all the times by providing a change over switch with lapping contacts connecting to ground with a direct grounding, a low resistance grounding and with a direct current power source between a neutral point of alternating current high voltage bus-bars and a ground.
CONSTITUTION: Between a neutral point of alternating current high voltage bus- bars and a ground, a change over switch 8 with lapping contacts changing over grounding terminals a - c by a direct grounding, a low resistance grounding 9 and with direct current power source 10 is provided. As terminals a - c can be changed over as lapping type by this change over switch 8, together with preventing a perfect short circuitting of a direct current power source 10 at a time of changing over, a neutral point is grounded to the earth directly or with a low rsistance always when an operation of changing over and even when a direct current voltage is applied duplicatingly with an alternating current voltage of bus-bars. Accordingly a direct current voltage can be duplicatingly applied to a directly grounded system safely and easily.
