A dry-type transformer vibration and noise reduction device

Abstract

The invention discloses a vibration and noise reduction device for a dry type transformer. The vibration and noise reduction device is characterized in that a transformer box is fixedly mounted in a sound insulation box, an upper limit vibration reduction plate is mounted on the upper portion in the transformer box through a left roller and a right roller, a lower limit vibration reduction plate is mounted on the lower portion in the transformer box through a left roller and a right roller, a transformer iron core is fixed on the lower limit vibration reduction plate through a mounting column, a left spring cylinder is fixedly mounted on the left of the upper limit vibration reduction plate, a right spring cylinder is fixedly mounted on the right of the upper limit vibration reduction plate, a left vibration reduction spring is fixedly mounted in the left spring cylinder, a right vibration reduction spring is fixedly mounted in the right spring cylinder, the top end of the left vibration reduction spring and the top end of the right vibration reduction spring are fixedly mounted at the top in the transformer box, a vibration reduction air bag is mounted between the lower limit vibration reduction plate and the bottom of the transformer box, a radiating air cylinder is fixedly mounted on the left lateral wall of the transformer box, and an air inlet radiating cylinder is fixedly mounted on the right lateral wall of the transformer box. The vibration and noise reduction device is scientific and reasonable in design, simple in structure and convenient to operate.

Description

Technical field: [0001] The invention relates to a dry-type transformer vibration and noise reduction device, which belongs to the technical field of transformers. Background technique: [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be used for long-term...

AI Technical Summary

Problems solved by technology

[0003] In the use of dry-type transformers, vibration reduction and noise reduction are necessary measures. There is no vibration reduction and noise reduction structure inside the existing dry-type transformers. During the operation of the transformer, the vibration and noise are relatively large.
