Abstract
PURPOSE: To make the device economical with a less vacuum switches used, by providing vacuum switches of current switching element, a current limiting resistor of current limiting element and a switch having a movable arm for successively bridging fixed contacts.
CONSTITUTION: For an operation of change-over from a tap 3 to 2, the action is made in such manner, firstly with a vacuum switch A closed, secondly with a bridging movable arm a turning to bridge contacts a1, a2, thereafter making an engagement only with a2, further with an engagement only to a3 after bridging a2, a3. Accordingly, the load current is diverted flowing from the vacuum switch A to a current limiting resistor 6, further commutated to a vacuum switch B, and fed to an output terminal 8 from the tap 2. In this way, the vacuum switches A, B, with their conduction only required for a short length of time during the tap change-over, can be made small in size, simultaneously with a protection made capable for an anomalous voltage by the selection of a disconnector switch 9 and for a short-circuit between the taps by fuses 7a, 7b, respectively.
