Abstract: Proposed is an air gap adjustment apparatus. The apparatus is for enabling an air gap between the inner surface of a stator and the outer surface of a rotor, which are installed in an inner space of a housing, to be uniform overall. A plurality of fastening holes are formed so as to surround a shaft through hole of an end plate constituting the housing. A fastener, which has passed through a bearing housing of a bearing, is fastened to each fastening hole so as to mount the bearing to the end plate. An adjusting member body of an adjusting member, which has passed through the bearing housing, is positioned in an adjusting member seating part which is formed at the entrance of each fastening hole. The adjusting member rotates about the adjusting member body so that a head part may adjust the position of the bearing.

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.

Abstract: The present invention relates to a transformer iron core. The present invention comprises: an upper yoke (50); a lower yoke (51) extending in parallel with the upper yoke (50); and an end leg (60) which is installed between the upper yoke (50) and the lower yoke (51), which extends perpendicularly to the longitudinal direction of the upper yoke (50) and the lower yoke (51), and which is coupled to the upper yoke (50) and to the lower yoke (51). The upper yoke (50) and the lower yoke (51) are made by laminating multiple yoke steel plates (50′). The end leg (60) is also made by laminating multiple leg steel plates (60′). The upper yoke (50) and the lower yoke (51) have leg coupling portions (52) on both ends thereof. The end leg (60) has yoke coupling portions (62) coupled to the leg coupling portions (52).

Abstract: Provided is a transformer having a noise reducing means. The transformer includes: an iron core (P), which is formed by stacking a plurality of steel sheets, and has stepped parts (S) formed at a portion thereof with different widths; and the noise reducing means provided at the stepped parts (S) so as to increase coupling force among the plurality of steel sheets. The noise reducing means includes: pressing bars (30) mounted on the stepped parts (S) of the iron core (P), and having plane-shaped horizontal pressing surfaces (31) in the direction in which the steel sheets are stacked; and a binding (90) for surrounding the outer surface of the iron core (P) including the pressing bars (30), so as to press the pressing bars (30) in the stacking direction of the steel sheets.

Abstract: Provided is a brace apparatus for a transformer tank and a method for determining the length thereof. The brace apparatus is mounted on a transformer tank so as to reinforce the transformer tank. The brace apparatus has a brace main body forming the exterior thereof, and in order to block the occurrence of resonance in an inner space of the brace main body, the length of the brace main body is set to be at a value at which resonance does not occur in the inner space, or a partition plate is provided to the brace main body so as to block the occurrence of resonance. In present invention, the length of the brace apparatus may be set by means of a simple configuration, thereby enabling the prevention of noise from occurring due to resonance.
