Description

Technical Field

[0001] The utility model belongs to the technical field of reactor design and manufacturing, and particularly relates to a bracket tooling for magnetic shunt transportation. Background Art

[0002] The magnetic shunts of the reactor are installed at the upper and lower ends of the reactor body to absorb magnetic flux leakage and prevent overheating. The magnetic shunts are made by stacking several silicon steel sheets. After stacking, one of the edges is first polished and then welded to ensure that each silicon steel sheet is welded together.

[0003] Since the manufacturing cycle of magnetic shunts is generally 4 to 5 days, and the magnetic shunts are large in size and require a large number of silicon steel sheets, up to several thousand sheets, the large vibrations during transportation after welding the silicon steel sheets can cause cracks at the welding points, rendering the magnetic shunt unusable and requiring reprocessing, which in turn increases manufacturing costs, extends the production cycle of reactor products, and reduces reactor production efficiency. Therefore, the magnetic shunts are manufactured near the reactor products to be assembled to ensure the overall quality of the magnetic shunts.

[0004] In order to further ensure the cleanliness of the reactor products and the adjustment of the manufacturing process, the magnetic shunt cannot be processed and manufactured near the reactor products to be assembled. After manufacturing, it must be separately packaged and transported over long distances before it can be assembled on the reactor products. However, there is a risk of rust and cracking in the transportation of the magnetic shunt silicon steel sheets, which may result in the magnetic shunt being unable to be installed and used normally.
