A vibration reduction unit comprising:
- a first frame forming one portion of the exterior thereof;
- a second frame which forms the other portion of the exterior thereof, and which is coupled to the first frame;
- a resonance space formed inside the second frame so as to reduce transmitted vibration or noise by means of resonance;
- and
- a pipe member penetratively coupled to the first frame such that the resonance space communicates with the outside.
A transformer comprising:
- an electrical connection unit that is electrically connected to an external power supply and an external load, converts power transferred from the power supply and provides the converted power to the load;
- a housing having an accommodation space for accommodating the electrical connection unit and a wall portion surrounding the accommodation space;
- and
- a vibration reduction unit accommodated in the accommodation space and each coupled to the housing and configured to reduce vibration or noise generated from the electrical connection unit,
- wherein the vibration reduction unit comprises:
- a first frame forming one side toward the electrical connection unit;
- a second frame coupled to the first frame and the wall portion, respectively;
- a resonance space formed inside the second frame so as to reduce the transmitted vibration or noise by means of resonance;
- and
- a pipe member penetratively coupled to the first frame such that the resonance space communicates with the accommodation space.
