5.6 Installation of dry-type transformer

5.6.1 Remove the packing box of the dry-type transformer, hang it on the roller bar, and slowly push it to the side of the channel steel foundation. If necessary, it can be pulled by a hoist on the lock frame at the lower 1/3 of the transformer.

5.6.2 When the dry-type transformer is directly fixed on the section steel, use a three-legged pole and a hoist to lift the transformer into place, use a spirit level, a plumb line, and a steel ruler to measure the deviation in position, and use the method of padding to reduce the deviation to within the excellent range. Use electric welding between the thin iron sheets and between the thin iron and the basic steel, and make corresponding marks on the transformer base. Generally, there should be no more than 3 gaskets, and the gaskets should not be exposed outside the base.
