Abstract

Un système d'extraction de l'énergie induite par couplage capacitif dans un fil de garde par des faisceaux conducteurs d'une ligne de transport d'énergie C.A.. Ce système a une sortie et comprend un dispositif abaisseur de tension transformant l'énergie induite dans le fil de garde en une tension de sortie C.A., et des moyens pour régulariser cette tension de sortie C.A.. Ces moyens de régularisation sont montés en dérivation entre le dispositif abaisseur de tension et la sortie et comprennent un circuit de commutation relié au dispositif abaisseur de tension. Ce système est avantageusement caractérisé en ce que le circuit de commutation fonctionne dans l'une et l'autre des polarités possibles de la tension et en ce que les moyens de régularisation comprennent en outre: - une inductance reliée en série entre le circuit de commutation et le dispositif abaisseur de tension, de façon à pouvoir inverser la polarité de la tension et bloquer le circuit de commutation après sa mise à feu dans une polarité jusqu'à ce qu'il soit mis à feu dans l'autre polarité; et - un circuit de contrôle suivant la polarité et l'amplitude de la tension de sortie C.A. pour commander de façon sélective la mise à feu du circuit de commutation, ce circuit de contrôle comprenant des moyens asservis à la phase de la tension de sortie C.A. et à la polarité du circuit de commutation, pour mettre à feu le circuit de commutation successivement dans une polarité, puis dans l'autre.
