Description

A dry-type transformer seismic support structure

technical field

The utility model relates to a dry-type transformer, in particular to a supporting structure of the dry-type transformer.

Background technique

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. The cooling method is 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 continuous overload operation.

The base structure of the traditional dry-type transformer is not reasonable enough, the positioning is inconvenient when installing the coil, and the shock absorption performance is not good. The coil of the dry-type transformer is easily affected by vibration and loosens, which in turn affects the safety of the dry-type transformer. For this reason, We propose a dry-type transformer seismic support structure.
