Problems solved by technology

For large-scale transformers, since the iron yoke weighs several tons and has a long and wide sheet shape, sometimes the upper iron yoke is still broken, so the rigidity is extremely poor. When the upper iron yoke is assembled, the iron yoke assembly is very curved. It often results in the inability to clamp the upper iron yoke, which seriously affects the product quality of the transformer

Embodiment

[0022] Please refer to Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5 .

[0023] The method of assembling the upper iron yoke of the transformer is to first insert part of the upper iron yoke silicon steel sheet into the middle of the iron core column 3, and then insert the T-shaped frame 2 in the middle of the iron core column, and insert the T-shaped frame 2 into the middle of the iron yoke silicon steel sheet first, Then insert the rest of the upper iron yoke silicon steel sheet into the iron core column 3 along both sides of the T-shaped frame 2. After all the upper iron yoke silicon steel sheets are inserted into the iron core column 3, take out the T-shaped frame 2 through the hanger 1 on the T-shaped frame 2. , and finally clamp the iron yoke silicon steel sheet with bolts, thus completing the assembly process of the iron yoke on the transformer.

Abstract

Steps for installing iron yoke into iron core stem are as following: inserting T type rack into iron core stem; inserting piece of up iron yoke into iron core stem; picking up T type rack; fastening yoke to complete assembling. Advantages of the method are: simple technique, easy of operation, safe and reliable. The method is especially suitable to assembling up iron yoke on transformer in large capacity.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a method for assembling iron yokes on transformers. Background technique [0002] The currently known method for assembling the upper iron yoke of a transformer is to manually insert the upper iron yoke pieces into the iron core columns one by one. The conventional upper iron yoke can be completed smoothly without adopting new means due to its light weight and small sheet shape. For large-scale transformers, since the iron yoke weighs several tons and has a long and wide sheet shape, sometimes the upper iron yoke is still broken, so the rigidity is extremely poor. When the upper iron yoke is assembled, the iron yoke assembly is very curved. It often causes the upper iron yoke to be unable to be clamped, which seriously affects the product quality of the transformer. Contents of the invention [0003] The invention provides an iron yoke assembly method on a transformer to...
