Title (EN) INDUCTION COUPLER OF POWER LINE CARRIER COMMUNICATION SYSTEM
(FR) COUPLEUR PAR INDUCTION D'UN SYSTÈME DE COMMUNICATION À PORTEUSE SUR LIGNE DE TRANSPORT D'ÉNERGIE
(JA) 電力線搬送通信システムの誘導結合装置
Abstract:
(EN) An induction coupler of a power line carrier communication system has magnetic cores (3a, 3b) having an aperture (20) for passing a power line (2) as a primary winding, and a signal lead wire (10) as a secondary winding passed through the aperture (20), wherein the magnetic cores (3a, 3b) are arranged on the grounded sheath of the power line and the magnetic cores (3a, 3b) grounded.
(FR) L'invention concerne un coupleur par induction d'un système de communication à porteuse sur ligne de transport d'énergie qui possède des noyaux magnétiques (3a, 3b) comportant une ouverture (20) destinée à faire passer une ligne de transport d'énergie (2) en tant que câblage principal et un câble conducteur de signal (10) en tant que câblage secondaire ayant traversé l'ouverture (20), où les noyaux magnétiques (3a, 3b) sont disposés sur la gaine mise à la masse de la ligne de transport d'énergie et où les noyaux magnétiques (3a, 3b) sont mis à la masse.
(JA)  一次巻線としての電力線2を通すアパーチャー20を有する磁気コア3a,3bと、アパーチャー20に通した二次巻線としての信号導線10とを備え、磁気コア3a,3bが接地シース付き電力線の接地シース上に設置され磁気コア3a,3bが接地される。
