Abstract

The invention discloses a vibration-reducing and noise-reducing dry-type transformer, which includes a main body, an iron core and a clamping fastener, and a shock-absorbing pad is installed between the iron core and the clamping fastener. The advantage of the present invention is that by installing vibration damping parts with materials and reasonable structures between the solid installations in contact with the iron core of the dry-type transformer, and binding the inner structure of the iron core, the dry-type transformer can maintain the original performance. In addition, it can reduce vibration and transmission noise, improve the performance of dry-type transformers, and at the same time improve the noise pollution of the equipment use environment, especially suitable for places with special requirements for noise or installation conditions.

Description

technical field [0001] The invention relates to a dry-type transformer, in particular to a dry-type transformer capable of reducing vibration and transmission noise. Background technique [0002] The vibration of the dry-type transformer during operation will not only generate noise through the installation device, but also have a certain impact on the performance of the dry-type transformer after long-term operation. When the natural vibration frequency of the dry-type transformer itself is the same as the current frequency, resonance will occur, and the impact will be more obvious, and the vibration and noise generated by the dry-type transformer with larger capacity are particularly prominent. [0003] The dry-type transformer is mainly composed of the transformer body including the coil, the iron core and the clamping fasteners, and the iron core is the main source of vibration, and the vibration transmission between it and the clamping fasteners is the main cause of the...
