METHOD OF MANUFACTURING TRANSFORMER WITH ASSEMBLED TRIANGULAR MAGNETIC CIRCUIT Russian patent published in 2018 - IPC H01F27/245 H01F27/26 H01F41/02 H01F27/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. Method comprises the step of assembling triangular magnetic circuit (1) comprising the following steps, in which: a) two halves (2a) of the rod are positioned on plate (14) of the assembling jig base in the horizontal position using lower part (16a) of the adapters to maintain the desired angle between two halves (2a) of one rod (2); b) the halves set to the desired position are attached using upper part (16b) of the adapters and fixing bar (17) placed onto steel studs (15); c) outer clamping plate (6) is positioned under two halves (2a) of the rod at one end of rod halves (2a); d) yoke segment (3) is assembled at one end of two halves (2a) of yoke rod (2), where the yoke segment has a shape consistent with the shape of the ends of two opposite halves (2a) of the yoke rod; e) inner clamping plate (7) is positioned onto the surface of yoke segment (3) and onto two halves (2a) of the yoke rod and both clamping plates (6) and (7) are tightened together, thus forming first frame clamp (5); f) second frame clamp (5) is formed on the other end of two halves (2a) of yoke rod (2) repeating steps c)–e); g) the first clamp and the second clamp are tightened together with a fastener; h) separate frame (5) of the magnetic circuit is turned to the vertical position and released is fixing bar (17) of the assembling jig or fixing bar (17) of the assembling jig is released first and then separate frame (5) of the magnetic circuit is lifted to the vertical position; i) two additional magnetic circuit frames (5) are assembled repeating steps a)–h); j) all three frames (5) of the magnetic circuit are set to the thrust position and are mechanically tightened together in the lower and the upper parts of the frames.

EFFECT: technical result is simplifying the manufacture.
