Definitions

  • the purpose of the invention is to compensate an inductive circuit, i.e. to eliminate the inductive inertia and thereby eliminate the reactive power and maximize the current amplitude but without using capacitors or idling rotating machines.
  • the invention constitutes a solution to this problem.
  • a coil is connected in series with the primary circuit. This coil is magnetically connected to another coil (through an iron core) which is connected in series with the secondary circuit (i.e. a transformer).
  • the voltage of the secondary circuit is switched on and off in the right moment by the rotating breaker and the rise of the secondary current is controlled by the resonance circuit.
  • the device functions in the following way:
  • the resonance circuit creates a suitable rise of the current with a duration of one quarter of a cycle.

Abstract

Dispositif destiné à compenser la puissance réactive (inductive) de circuits à c.a. La puissance inductive qui est provoquée par l'auto-inductance, c'est-à-dire une inertie lorsque les électrons sont accélérés, est un problème qui limite la puissance utile qui peut être transmise à des réseaux à c.a. Normalement, le problème est résolu par la compensation à l'aide de condensateurs ou de machines tournant au ralenti. La présente invention résout ce problème par la connexion d'un transformateur au circuit primaire. Le bobinage secondaire du transformateur est alimenté par une tension de c.c. pendant la première moitié de chaque demi-cycle du courant primaire. Un circuit de résonance commande l'augmentation du courant continu qui induit une énergie magnétique dans le circuit primaire qui compense l'auto-inductance. Ledit dispositif est régulé automatiquement et de façon infiniment variable par un régulateur qui est connecté à un dispositif de mesure du facteur de puissance (cos fi). L'interruption du circuit secondaire peut être obtenue à l'aide d'un disjoncteur mécanique, de thyristors ou d'un convertisseur de fréquence statique. Dans un autre mode de réalisation, le circuit secondaire est constitué par un bobinage supplémentaire dans un transformateur de puissance normal.
