Title
(EN) SIGNAL FILLING/EXTRACTION DEVICE
(FR) DISPOSITIF DE REMPLISSAGE/EXTRACTION DE SIGNAL
(JA) 信号注入・抽出装置
Abstract
(EN) It is possible to easily fill a communication signal in current flowing in a linear conductor and easily extract the communication signal from the current flowing in the linear conductor as well as realize this filling and extraction without being affected by low-frequency large current flowing in the linear conductor. A signal filling/extraction device includes a ferromagnetic core (2) through which a power line (1) passes. The ferromagnetic core (2) has a second winding (3) arranged around it and the winding (3) is connected to an amplifier (4) and an LPF (5). The current of the power line (1) amplifies the current induced from a magnetic flux Φ1 generated by the ferromagnetic core (2) and removes high frequency. The current thus obtained flows into a third winding (6) around the ferromagnetic core (2) and generates a magnetic flux Φ2 of reverse phase canceling the low-frequency current portion of the magnetic field Φ1 of the ferromagnetic core (2). A high frequency signal is extracted through a first winding (7) from the magnetic flux of the remaining high-frequency portion. On the contrary, the current for the signal applied to the first winding (7) is filled in the commercial current of the power line (1).
(FR) Il est possible de remplir aisément un signal de communication dans un écoulement de courant dans un conducteur linéaire et de l'en extraire facilement ainsi que de réaliser son remplissage et son extraction sans être affecté par l'écoulement de courant important basse fréquence dans le conducteur linéaire. Le dispositif de remplissage/extraction de signal comprend un noyau ferromagnétique (2) à travers lequel une ligne d'alimentation (1) passe. Le noyau ferromagnétique (2) présente un second roulement (3) disposé autour et l'enroulement (3) est connecté à un amplificateur (4) et à un LPF (5). Le courant de la ligne d'électricité (1) amplifie le courant induit depuis un flux magnétique $g(F)1 généré par le noyau ferromagnétique (2) et élimine la haute fréquence. Le courant ainsi obtenu s'écoule dans un troisième enroulement (6) autour du noyau ferromagnétique (2) et génère un flux magnétique $g(F)2 d'une phase inverse supprimant la partie de courant basse fréquence du champ magnétique $g(F)1 du noyau ferromagnétique (2). Un signal haute fréquence est extrait à travers un premier enroulement (7) du flux magnétique de la partie haute fréquence restante. Le courant pour le signal appliqué sur le premier enroulement (7) est rempli dans le courant commercial de la ligne d'électricité (1).
(JA) 本発明の目的は、通信信号を、線状導体を流れる電流に容易に注入できるとともに、その線状導体を流れる電流から通信信号を容易に抽出でき、この注入および抽出を、線状導体を流れる低周波数の大電流の影響を受けずに実現可能にすることである。本発明は、電力線1が貫通する強磁性体コア2を備え、該強磁性体コア2には第2の巻線3が巻回され、該巻線3にはアンプ4とLPF5が継続されており、電力線1の電流により強磁性体コア2が発生する磁束Φ1から誘導される電流を増幅し、高周波を除去する。こうして得られた電流は、強磁性体コア2に巻回された第3の巻線6に流れ、強磁性体コア2の磁界Φ1の低周波電流相当部分をキャンセルする逆位相の磁束Φ2を発生させる。残る高周波部分の磁束から第1の巻線7を通して高周波信号を抽出する。逆に第1の巻線7に加えた信号用電流を、電力線1の商用電流に注入する。
