Title (EN) ELECTRICAL LEAK DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE FUITE ÉLECTRIQUE
(JA) 漏電検出装置
Abstract:
(EN) Provided is an electrical leak detection device galvanically isolating a battery from a vehicle body and accurately detecting the degradation of an insulating resistance. A battery pack (106) isolated from the vehicle body has an assembled battery (102) to which a primary winding (109) is connected in parallel. A current detection circuit (116) is configured by having: an ammeter-side secondary winding (113) transformer-coupled to the primary winding (109); an AC power supply (114) connected to the ammeter-side secondary winding (113) in series; and an ammeter (115) connected between the vehicle body and the AC power supply (114). The ammeter (115) detects leak current by supplying AC current from the current source (114) to the ammeter-side secondary winding (113). As described above, the battery pack (106) and the current detection circuit (116) connected to the vehicle body are galvanically isolated from each other by using a transformer.
(FR) L'invention concerne un dispositif de détection de fuite électrique isolant de manière galvanique une batterie d'un corps de véhicule et détectant précisément la dégradation d'une résistance isolante. Un bloc-batterie (106) isolé du corps de véhicule a une batterie assemblée (102) à laquelle un bobinage primaire (109) est connecté en parallèle. Un circuit de détection de courant (116) est configuré en ayant : un bobinage secondaire côté ampèremètre (103) couplé par transformateur au bobinage primaire (109) ; une alimentation électrique alternative (114) connectée en série au bobinage secondaire côté ampèremètre (113); et un ampèremètre (115) connecté entre le corps de véhicule et l'alimentation électrique alternative (114). L'ampèremètre (115) détecte le courant de fuite en distribuant du courant alternatif à partir de la source de courant (114) vers le bobinage secondaire côté ampèremètre (113). Tel que décrit ci-dessus, le bloc-batterie (106) et le circuit de détection de courant (116) connectés au corps de véhicule sont isolés de manière galvanique l'un de l'autre par utilisation d'un transformateur.
(JA)  電池を車両ボディから直流的に絶縁するとともに、高精度で絶縁抵抗の劣化を検出する漏電検出装置を提供する。車両ボディと絶縁された電池パック106が有する組電池102に、一次巻線109を並列に接続する。また、一次巻線109とトランス結合される電流計側二次巻線113と、電流計側二次巻線113に直列に接続される交流電源114と、車両ボディと交流電源114との間に接続される電流計115とを有する電流検出回路116を構成する。そして、電流源114から交流電流を電流計側二次巻線113に供給することにより、電流計115で漏電電流を検出する。以上のように、トランスを用いて、電池パック106と車両ボディに接続された電流検出回路116とを直流的に絶縁する。
