Title
(EN) CURRENT SENSOR
(FR) CAPTEUR DE COURANT
(JA) 電流センサ
Abstract
(EN)
A current sensor (1) is comprised of a core (3) which collects the magnetic flux generated by the current to be measured, a Hall element (2) which outputs the electrical signal corresponding to the magnetic flux collected by the core, a circuit board (4), and a cabinet (5) which houses the other components. The cabinet (5) is constructed from, for example, an insulating material. The Hall element (2) and an amplifier for amplifying the output signal thereof are provided on the circuit board (4). A connecting wire (9) to make the static electricity which moved from the cabinet (5) constructed from an insulating material to the core (3) escape to the circuit board (4) is provided between the core (3) and the circuit board (4).

L'invention porte sur un capteur de courant (1), qui est constitué d'un noyau (3) qui recueille le flux magnétique généré par le courant à mesurer, un élément Hall (2), qui envoie en sortie le signal électrique correspondant au flux magnétique recueilli par le noyau, une carte à circuits imprimés (4), et un boîtier (5), qui enveloppe les autres composants. Le boîtier (5) est construit par exemple en un matériau isolant. L'élément Hall (2), et un amplificateur pour amplifier son signal de sortie, sont prévus sur la carte à circuits imprimés (4). Un fil de connexion (9), destiné à faire en sorte que l'électricité statique qui va du boîtier (5) construit en un matériau isolant au noyau (3) s'échappe de la carte à circuits imprimés (4), est disposé entre le noyau (3) et la carte à circuits imprimés (4).
