    摘要: Current stabilisers are for example required in airport navigation lights and have set value determining units and real value sensing units, as well as real value/set value comparing units. In the described current stabiliser with step-up transformer, a unit (50) for selecting a base voltage is associated to the primary side of the step-up transformer (1, 2, 10) and a switching regulator module (80) supplies a base voltage-superimposed power.

    摘要: Le convertisseur de puissance (10) sert à la préparation d'une puissance électrique pour un utilisateur (12), la puissance étant tirée d'une source de puissance (11) et adaptée quant aux grandeurs électriques aux besoins de l'utilisateur (12). Le convertisseur (10) comporte dans sa version la plus simple exclusivement un transformateur (13) et une résistance inductive connectée en série avec ce dernier et formant un organe de réglage (14). Cet organe (14) est constitué de deux noyaux en ferrite (111, 112) en forme d'anneaux fermés, identiques disposés coaxialement et qui sont entourés chacun d'une des parties d'un enroulement (150) d'induction et ensemble d'un enroulement de commande (117). Celui-ci est relié à une commande (30) qui règle à l'aide d'un courant (I) de commande la valeur de l'inductance propre L de l'organe de réglage (14) pouvant être variée dans une gamme étendue (1:100). L'organe de réglage (14) agit par son inductance propre L correspondante sur le courant alternatif (i) circulant dans son enroulement d'induction (150) à la manière d'une bobine de réactance de même inductance propre L, c'est-à-dire sans distorsion. La connexion en série de l'organe de réglage (14) et du transformateur (13) exerce ainsi sur le courant alternatif (i) l'effet d'un simple diviseur de tension réglable électriquement.

    摘要: This invention relates to electrical automatic systems able to restore the reference values of the AC variable voltage. The system of power circuit-breakers provides protection of an AC voltage regulator. A double-pole power circuit-breaker 21 is connected so that its first contact is made between the input of the mains phase conductor and the point of connection of the input of a regulating unit 2 and one of the outputs of a shunt release 22, which is the input of an additional protection unit 16 made as a diode bridge 17 whose output is connected to power electrodes of a protection thyristor 18. The second output of the shunt release 22 is connected to the input of the diode bridge 17, the second contact of the double-pole power circuit breaker is connected between the output of the regulating unit 2 and a point of connection of a load 3 and an output capacitor 15, thereby forming a triple-pole circuit-breaker the contacts of which are connected in a specific circuit between the second end of the transformer primary winding and mains 1. A stand-by double-pole power circuit-breaker 26 is connected between the mains and the load, and a remote control button 27 is connected between the first output of the shunt release 22 of the double-pole power circuit-breaker and the neutral conductor. Disclosed are the embodiments of an AC voltage regulator providing the step-down, step-up; step-up and step-down modes of operation for a separate voltage regulator and a voltage regulator in a cascade circuit with extended protection and service functions along with the improvement of some units.

    摘要: Zur Verringerung von Verlustleistung, Gewicht und Schaltzeiten umfaßt eine Transformatorschaltung wenigstens eine Stelleinheit (144), bei der die erste Wicklung (9) eines Transformators (8) einen Eingangsanschluß (2) mit einem Ausgangsanschluß (5) verbindet. Durch Schalter (150 bis 153) ist an eine weitere Wicklung (11) des Tranformators entweder die Eingangsspannung oder die Ausgangsspannung der Stelleinheit anlegbar, wodurch auf die Eingangsspannung eine in der ersten Wicklung induzierte Spannung (A U) additiv oder subtraktiv aufgeprägt wird. Die weitere Wicklung kann mit antiparallelem Wicklungssinn zur ersten Wicklung parallelgeschaltet oder kurzgeschlossen werden, wodurch die Ausgangsspannung gleich der Eingangsspannung wird. Wird der kreis der weiteren Wicklung geöffnet, drosselt die erste Wicklung den Laststrom. Für ein schnelles Umschalten werden kurzzeitig alle Schalter gleichzeitig geschlossen, wobei eine Strombegrenzungsschaltung (157) den Kurzschlußstrom begrenzt. V-MOS-Transistoren als Shalter verkürzen die Umschaltzeiten weiter. Zwei oder mehr Stelleinheiten können in Reihe geschaltet werden und dienen mit einer Meßfühleranordnung, einer Komparatoranordnung und einer Schaltersteuerung als Spannungskonstanter oder Spannungsregler.

    摘要: A static controlled reactance device (10) is inserted in series with an AC electric power transmission line (6, 8) to adjust its transfer impedance. An inductor (X, 20)(reactor) is serially connected with two back-to-back connected thyristors (24, 26) which control the conduction period and hence the effective reactance of the inductor (21). Additional reactive elements are provided in parallel with the thyristor controlled reactor to filter harmonics and to obtain required range of variable reactance. Alternatively, the static controlled reactance device (10) discussed above may be connected to the secondary winding of a series transformer (12) having its primary winding connected in series to the transmission line. In a three phase transmission system, the controlled reactance device (10) may be connected in delta configuration on the secondary side of the series transformer (12) to eliminate triple harmonics. With series transformer (12), secondary windings to which the controlled reactances are connected could be arranged for six-pulse or twelve-pulse operation.
