Title:
STEREOSCOPIC TRANSFORMER WOUND CORE HAVING ISOSCELES TRIANGLE YOKES
Document Type and Number:
WIPO Patent Application WO/2018/161641
Kind Code:
A1
Abstract:
A stereoscopic transformer wound core having isosceles triangle yokes, comprising three core limbs and six yokes. The three core limbs and the six yokes are formed by the assembly of three rectangular single frames (1). The sizes and shapes of two of the rectangular single frames are completely identical, and the length of the yoke of the remaining rectangular single frame is greater than that of the yokes of the other two rectangular single frames, the three rectangular single frames have an equal height, two adjacent rectangular single frames are assembled to form core limbs with the cross section being a polygon externally connected to a whole circle. The stereoscopic transformer wound core can decrease the transformer transportation width, lower the transportation difficulty, reduce costs, and provide the shortest path for tapping a coil to a tapping switch through a lead, thereby greatly simplifying the lead arrangement.
