<p>In a transformer having a multipoint connection module inside and a drive device for operating a tap changer, the present invention includes multiple multipoint connection modules which respectively include: a support plate; multiple fixed contacts which are fixated on one side of the support plate in a circular arc direction at regular intervals; and a rotation contact (530) which is in contact with each of the fixed contacts by rotating at the center of the support plate; and an axis joint part which is formed on a straight line with each rotation contact (530) in order to rotate the rotation contact (530) of the multipoint connection module simultaneously. Accordingly, efficiency increases by easily moving the electrical connection point of a tap since resistance is not generated. Each deviation decreases since multiple taps use a same axis. A failure rate remarkably decreases since an arc is not generated in a part where a tap is combined. Quality and stability are also obtained by selecting a structure for protection against dust, water resistance, and sealing for the drive device.</p> |
