Description
Przewodniki sprzegajace dla elektrycz¬ nych przewodów napowietrznych skladaja sie zazwyczaj z drutów przewodzacych, które sa owiniete naokolo rdzenia z dru¬ tów zelaznych lub stalowych w ksztalcie linki lub sruby drutowej, albo tez w ksztal¬ cie obu.Mniemano dotychczas, ze przy uzy¬ ciu zelaza w tym wypadku nie powstaja w rdzeniu wewnatrz przewodnika szkodliwe straty magnetyczne.Doswiadczenie wykazalo jednak, ze maja tu miejsce straty energji na histereze i prady wirowe.Wedlug wynalazku celem zmniejsze¬ nia lub pominiecia strat ma byc uzyty dla rdzenia metal, który przy wysokiej wy¬ trzymalosci na rozciaganie i sciskanie po¬ siada te zalete, ze nie jest magnetycz¬ nym, jak naprzyklad bronz lub jakikol¬ wiek stop zelaza o bardzo slabych wla¬ snosciach magnetycznych, W razie koniecz¬ nosci zastosowania drutów z metalu ma¬ gnetycznego, albo celem zwyzki skutecz¬ nosci przy metalu niemagnetycznym, moz¬ na druty podzielic albo izolowac jeden od drugiego.W koncu przy uzyciu metali magne¬ tycznych straty wedlug wynalazku maja byc zmniejszone przez zastosowanie metali/ z malymi stratami inagnetycznemi, z mala przewodnoscia elektryczna, albo takie, które posiadaja ^równoczesnie obie za¬ lety./ '**"" *' . PL PLInterconnecting conductors for overhead electrical conductors usually consist of conductive wires which are wrapped around a core of iron or steel wire in the form of a cord or wire screw, or both. Iron, in this case, no detrimental magnetic losses are formed in the core inside the conductor. Experience has shown, however, that energy losses due to hysteresis and eddy currents take place. According to the invention, in order to reduce or avoid losses, a metal is to be used for the core, which at high The tensile and compressive strength has the advantage of not being magnetic, such as bronze or any iron alloy with very weak magnetic properties. If you need to use magnetic metal wires, or In order to increase the effectiveness with non-magnetic metals, the wires can be divided or insulated from each other. Otherwise, the losses according to the invention are to be reduced by the use of metals (with low inagnetic losses, with low electrical conductivity, or those which have both advantages. "**" "*").
