Abstract

a. Dispositif de transmission d'énergie électrique sans contact, du type comprenant un enroulement primaire fixe de commande susceptible d'être alimenté en alternatif et en enroulement secondaire amovible disposé à l'intérieur d'un circuit magnétique lui-même enfermé dans un blindage de protection contre les inductions parasites; b. Ledit blindage est constitué par un écran magnétique fixe de fer saturable, conçu pour se saturer en présence du flux magnétique de commande engendré par l'enroulement primaire ; c. Mise à feu d'inflammateurs pyrotechniques.
