Abstract

Delta magnetno jezgro trofaznog transformatora, prečnika opisanog kruga jezgra d sastoji se od, tri identične kanure K izrađene namotavanjem paketa od traka trafo lima, spojene po površinama S, naznačeno time, što je svaka kanura (K) dobijena uzastopnim namotavanjem paketa (P1,P2,P3,P4...Pi...Pn) sa pomerenim počecima u odnosu na prethodne za margine (m2,m3,m4...mi...mn) na četvrtastom zaobljenom šablonu (A×B/R) od različitih traka konstantnih širina (w1,w2,w3,w4...wi…wn) u visinama naslaga (h1,h2,h3,h4...hi…hn) sa poprečnim presekom polovine nazubljenog kruga prečnika (d) čije isturene bočne ivice ravno namotanih paketa (P1,P2,P3,P4...Pi...Pn) sa jedne strane leže u ravni nagnutoj u odnosu nanormalu ose namotavanja za 30° i u spoju sa drugom kanurom (K) stvaraju aksijalne kanale za hladjenje jezgra a sa druge strane leže na površini tube oko šablona (A×B/R) prečnika (d) ostavljajući blage ivice po spoljnoj površini stuba za bolji raspored električnog polja i olakšano namotavanje namotaja.The Delta magnetic core of a three-phase transformer, the diameter of the described circle of core d, consists of three identical canoes K made by winding a packet of transformer strips connected to surfaces S, in which each canoe (K) is obtained by successive packet winding (P1, P2 , P3, P4 ... Pi ... Pn) with displaced beginnings relative to the previous ones for margins (m2, m3, m4 ... mi ... mn) on a square rounded pattern (A × B / R) of different a band of constant widths (w1, w2, w3, w4 ... wi… wn) in the heights of deposits (h1, h2, h3, h4 ... hi… hn) with a cross-section of half of a toothed circle of diameter (d) whose projecting lateral edges flat coiled packages (P1, P2, P3, P4 ... Pi ... Pn) on one side lie in a plane inclined with respect to the non-normal coiling axis by 30 ° and, in conjunction with the other canoe (K), form axial channels for cooling the core a on the other hand, they lie on the surface of the tube around a pattern (A × B / R) with a diameter (d) leaving slight edges on the outer surface of the pole for better arrangement of the electric field and also facilitated winding of the coils.
