Abstract

The invention discloses a simulation analysis method for mechanical vibration of dry-type transformer under marine transportation working condition, which utilizes finite element simulation software to simulate the structural size, the assembly relationship and the fixing form of a dry-type transformer to the greatest extent, ensures the grid quality and improves the solving efficiency. Corresponding ocean transportation machinery environment conditions are selected to simulate sea wave impact borne by the carrying ship; the dynamic swinging simulation motion of the transformer is completed; astress response value is obtained through simulation; according to the method, the structure where the mechanical strength of the transformer is most likely to fail in the ocean transportation process is judged, the problem that a load curve of sea wave impact cannot be simulated through transient impact simulation is solved, the reliability of the dry-type transformer under the ocean transportation working condition can be evaluated in advance in the product research and development stage, and the most reliable product structure is optimized.

Description

technical field [0001] The invention relates to the technical field of transformer transportation, in particular to a mechanical vibration simulation analysis method of a dry-type transformer under marine transportation conditions. Background technique [0002] Dry-type transformer is widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformer refers to a transformer whose iron core and winding are not immersed in insulating oil. Dry-type transformers are generally assembled in the factory, and then the assembled ones are transported to the destination. The most common method of transportation is to use ships to transport dry-type transformers to the destination. In order to prevent dry-type transformers from failing during transportation, generally adopt Transient shocks are simulated to simulate ship transportation to prevent dry-type transformers from failing after shipping. [0003] Howe...
