Abstract: A noise reduction device for a transformer is proposed. In this device, a blocking means or a connection support means is installed in a winding installed in an inner space of an enclosure in order to remove vibration and noise generated in the enclosure of the transformer. In a low voltage winding and a high voltage winding constituting the winding, when a current is applied, a magnetic flux flow is generated, thereby generating electromagnetic force. The electromagnetic force is transmitted to surfaces of the enclosure through insulating oil or the like inside the enclosure, causing vibration and noise. In order to cancel and eliminate the electromagnetic force, the blocking means or the connection support means is used. According to the disclosure, the electromagnetic force is canceled, thereby reducing the noise and vibration.
