Title (EN) EARTH LEAKAGE CIRCUIT BREAKER FOR ELECTRIC VEHICLE CHARGER
(FR) DISJONCTEUR DIFFÉRENTIEL POUR CHARGEUR DE VÉHICULE ÉLECTRIQUE
(KO) 전기자동차 충전기의 누전차단장치
Abstract:
(EN) The present invention comprises: a plurality of switches connected respectively to a current transfer line and a feedback transfer line between an external power source and a load; a diagnostic unit connected to a diagnostic line so as to output diagnostic current; an earth leakage sensor arranged to encompass the current transfer line, the feedback transfer line, and the diagnostic line, and sensing leakage current therefrom; and a control unit controlling opening/closing operations of the plurality of switches according to a comparison result between the leakage current and a reference value so as to control the connection between the external power source and the load, and thus the present invention has an advantage of allowing an electric vehicle charger to perform a self-diagnosis in real time.
(FR) La présente invention comprend : une pluralité de commutateurs connectés respectivement à une ligne de transfert de courant et à une ligne de transfert de rétroaction entre une source d'alimentation externe et une charge ; une unité de diagnostic connectée à une ligne de diagnostic de façon à délivrer un courant de diagnostic ; un capteur de perte à la terre conçu pour comprendre la ligne de transfert de courant, la ligne de transfert de rétroaction et la ligne de diagnostic, et détectant un courant de fuite qui en sort ; et une unité de commande commandant des opérations d'ouverture/fermeture de la pluralité de commutateurs en fonction du résultat d'une comparaison entre le courant de fuite et une valeur de référence de façon à commander la connexion entre la source d'alimentation externe et la charge. La présente invention présente donc l'avantage de permettre à un chargeur de véhicule électrique d'effectuer un auto-diagnostic en temps réel.
(KO) 본 발명은 외부전원과 부하 사이의 전류전송라인 및 피드백전송라인에 각각 연결된 다수의 스위치, 진단라인에 연결되어 진단전류를 출력하는 진단부, 전류전송라인, 피드백전송라인 및 진단라인을 둘러싸며 배치되고, 이들로부터 누설전류를 감지하는 누전센서 및 누설전류와 기준값의 비교 결과에 따라 다수의 스위치의 개폐동작을 제어하여 외부전원과 부하의 연결을 제어하는 제어부를 포함하여, 전기자동차 충전기에서 실시간으로 자가진단을 수행할 수 있는 이점이 있다.
