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 road 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 transported to the destination by kilometers. However, the structural integrity of dry-type transformers will directly affect the actual work and operation. Avoiding mechanical strength failure of the structure is an important issue in the design of transformer transportation schemes. After long-distance transportation by road, the dry-type transformer structure will be damaged by vibration. [0003] How...
