The present invention relates to a transformer having a plurality of multipoint connection modules and a driving device operating a switch device. Each of the multipoint connection modules includes: a support plate; a plurality of fixing contact points formed at regular intervals in an arc direction on one surface of the support plate; and a rotating contact point (530) connected to each of the fixing contact points by being rotated in the center of the support plate. A shaft joint portion is formed to be collinear with each of the rotating contact points (530) such that the rotating contact points (530) of each of the multipoint connection modules can be simultaneously rotated. An electrical connection point of a tap can be easily moved to prevent generation of resistance, thereby increasing efficiency. Further, the same shaft can be used for a plurality of taps to reduce a deviation of each of the taps. Further, an arc can be prevented near a coupling portion of each tap, thereby significantly reducing a failure rate. Further, dustproof, waterproof, and airtight structures can be adopted in the driving device, thereby securing quality and stability. |
