Method for manufacturing a stacked triangular core transformer

摘要

The present invention refers to the method for manufacturing a stacked triangular core transformer. The method is used in a production of distribution and power transformers using a stacked technology for core transformers. The method comprises a step of assembling a triangular core (1) which is comprising the following steps: a) positioning of two halves of one leg (2a) on the assembly stand on the horizontal position; b) securing the positioned halves using an upper part of adapters (16b) on the assembly stand; c) positioning of an outer clamping beam (6) underneath two leg halves (2a) at the one end of the leg halves (2a); d) assembling the yoke segment (3) at the one end of two halves (2a) of the core leg (2); e) forming a first clamp of the frame (5); f) forming a second clamp of the frame (5) at the other end of the two halves (2a) of the core leg (2) by repeating the steps "c" to "e"; g) tightening the first clamp and the second clamp together by securing means; h) rotating a single core frame (5) into vertical position and releasing securing bar (17) of the assembly stand; i) assembling two additional single core frames (5), by repeating steps "a" - "h"; j) positioning the all three single core frames (5) in abutting position, and then tightening them mechanically at the bottom and the top of the frames.
