Method for making stacked triangular core transformers

Abstract

The present invention relates to a method for manufacturing a stacked triangular core transformer. This method is used to produce distribution and power transformers using stacking technology for core transformers. The method includes the step of assembling a triangular core (1), which includes the following steps: a) positioning the two halves (2a) of one leg in a horizontal position on the assembly table; b) using the upper part of the adapter ( 16b) Fix the positioned halves on the assembly table; c) Position the outer clamping beam (6) at one end of the foot halves (2a) under the two foot halves (2a); d) Attach the yoke The segment (3) is assembled at one end of the two halves (2a) of the core leg (2); e) the first clamp forming the frame (5); f) at both ends of the core leg (2) The second clamp of the frame (5) is formed at the other end of the half (2a) by repeating steps "c" to "e"; g) the first clamp and the second clamp are tightened together by a fixing device; h ) Rotate the single core frame (5) to the upright position and release the fixing rod (17) of the assembly station; i) Assemble two additional single core frames (5) by repeating steps "a" – "h"; j) Position all three single core frames (5) in adjoining positions and tighten them mechanically at the bottom and top of the frames.

Description

technical field [0001] The present invention relates to a method for manufacturing a stacked triangular core transformer. The method is applied to the production of distribution and power transformers, which utilizes the stacking technology used for core transformers. Background technique [0002] The application of the triangular core concept is gaining increasing interest in the design of distribution and power transformers. It is claimed that triangular core transformers require less core material compared to planar cores. It also benefits from a smaller footprint and a fully symmetrical structure, which brings certain electrical advantages. If the transformer core is realized in winding technology, the level of no-load losses is additionally reduced. However, triangular cores are not easy to produce because their design is more complex compared to planar cores. Production is made more difficult because all three core legs are spatially positioned in 3D space, rather ...
