NEUARTIGE KONSTRUKTION EINER STROMSCHIENE MIT VORGEFÜLLTEM NATRIUM

Resumen de: DE102024135166A1

Eine Stromschiene (100) umfasst eine erste längliche Struktur (110A) und eine oder mehrere zweite längliche Strukturen (110B) aus einem leitenden Material zur Übertragung eines elektrischen Stroms. Wenigstens ein Abschnitt der Stromschienenstruktur weist einen hohlen Querschnitt mit einem inneren Hohlraum (112) auf. Der innere Hohlraum (112) ist mit einem Kühlmedium (120) vorgefüllt, um die Wärme zu absorbieren, die durch den von der Stromschiene (100) übertragenen elektrischen Strom erzeugt wird. Bei dem Kühlmedium (120) kann es sich um ein leitfähiges Phasenwechselmaterial wie Natrium handeln, das eine Phasenwechseltemperatur von 98 °C zwischen fest und flüssig aufweist. Wenn die Temperatur der Stromschiene 98 °C erreicht, absorbiert Natrium die Wärme, ohne dass die Temperatur der Stromschiene (100) ansteigt, und verhindert so einen Temperaturanstieg der Stromschiene (100). Da Natrium leichter ist, trägt es auch zur Gewichtsreduzierung der Stromschiene (100) bei, ohne die Strombelastbarkeit stark zu beeinträchtigen.
