Kind Code:
A
Abstract:

To provide a compact tap changer capable of changing taps at high speed and quietly while having a simple configuration with less driving mechanism compared with conventional ones, and to provide an inexpensive, quiet, and space-saving on-load tap changing pole transformer by employing the tap changer.

The tap changer includes: a tap-up driving unit for performing a tap-up driving by converting a linear motion of a plunger by a tap-up solenoid to a rotary motion so as to rotate a driving shaft; and a tap-down driving unit for performing a tap-down driving by converting a linear motion of a plunger by a tap-down solenoid to a rotary motion so as to rotate the driving shaft. An on-load tap changing pole transformer mounting the tap changer is provided.
