Title
(EN) ELECTRIC CURRENT SENSOR
(FR) CAPTEUR DE COURANT ÉLECTRIQUE
(JA) 電流センサ
Abstract
(EN) An electric current sensor has an electroconductive member (30) through which an electric current to be measured flows in a predetermined direction, and a magnetoelectric conversion part (10) which is separated from, and faces, the electroconductive member in an intersecting direction intersecting the predetermined direction. In a facing region (31) of the electroconductive member where the electroconductive member faces the magnetoelectric conversion part, an annular shape is formed in which two distal-end surfaces (36a) face each other via a gap (36b) around the predetermined direction. In the intersecting direction and via the gap, the magnetoelectric conversion part faces a void of the facing region forming the annular shape.
(FR) L'invention concerne un capteur de courant électrique comprenant : un élément électroconducteur (30) à travers lequel un courant électrique devant être mesuré circule dans une direction prédéterminée ; et une partie de conversion magnétoélectrique (10) qui est séparée de l'élément électroconducteur et lui fait face dans une direction d'intersection qui coupe la direction prédéterminée. Dans une région de face (31) de l'élément électroconducteur où l'élément électroconducteur fait face à la partie de conversion magnétoélectrique, une forme annulaire est formée dans laquelle deux surfaces d'extrémité distale (36a) se font face via un espace (36b) autour de la direction prédéterminée. Dans la direction d'intersection et via l'espace, la partie de conversion magnétoélectrique fait face à un vide de la région de face formant la forme annulaire.
(JA) 電流センサは、所定方向に被測定電流の流動する導電部材(30)と、前記所定方向に交差する交差方向で前記導電部材と離間して対向する磁電変換部(10)とを有する。前記導電部材における前記磁電変換部との対向部位(31)は、前記所定方向まわりに、2つの先端面(36a)が空隙(36b)を介して対向する環状を成す。前記磁電変換部は、環状を成す前記対向部位の備える中空と、前記交差方向において、前記空隙を介して対向している。
