    摘要: Eine Elektroanordnung für einen mit Wechselstrom betriebenen Lichtbogenofen (1) weist einen Umrichter (2) auf, der eine eine Netzfrequenz (f) aufweisende Netzspannung (U) eines Versorgungsnetzes (3) in eine eine Ofenfrequenz (f') aufweisende Primärspannung (U') umsetzt. Ein Ofentransformator (4) der Elektroanordnung transformiert die Primärspannung (U') in eine Sekundärspannung (U"). Die Sekundärspannung (U") wird einer Anzahl von Elektroden (6) des Lichtbogenofens (1) zugeführt. Die Elektroden (6) sind in einem Ofengefäß (8) des Lichtbogenofens (1) angeordnet. Sie beaufschlagen ein im
    Ofengefäß (8) befindliches Schmelzgut (9) mit Lichtbögen (10). Die Sekundärspannung (U") wird weiterhin einer ausgangsseitig des Ofentransformators (4) angeordneten Kondensatoranordnung (7) zugeführt, mit der der Ofentransformator (4) ausgangsseitig verbunden ist.

    摘要: This invention concerns power supplies suitable for electric arc gas heaters such a plasma torches. It more particularly relates to the dimensioning of the inductor in the switched-mode DC to DC converter used for feeding the torch. The invention concerns in particular a DC power supply for driving a non-transferred electric arc gas heater, comprising: an AC to DC rectifier providing a potential U 0; a DC to DC switching converter having a switching frequency fs; a current control loop having a latency Formula (I); and, a ballast inductor having an inductance L; characterized in that inductance L is such that Formula (II) and Formula (III). Such a design ensures the stability of the current control loop, while also ensuring a sufficient amount of current ripple to spread out the erosion zone on the electrodes of the torch.

    摘要: A plasma device which is provided with: a reaction container to which a metal starting material is supplied; a plasma torch which generates plasma between itself and the metal starting material within the reaction container, thereby evaporating the metal starting material and producing a metal vapor; a carrier gas supply unit which supplies, into the reaction container, a carrier gas for conveying the metal vapor; and a cooling tube which cools the metal vapor that is conveyed from the reaction container by the carrier gas, thereby producing a metal powder. The cooling tube is provided with: an indirect cooling section for indirectly cooling the metal vapor that is conveyed from the reaction container by the carrier gas and/or the metal powder; and a direct cooling section for directly cooling the metal vapor and/or the metal powder, said direct cooling section being continued to the indirect cooling section. At least a part of the inner wall of the indirect cooling section is provided with projections and/or recesses.
