Abstract
(EN)
The present invention provides a relay for a high voltage circuit. A switch of the relay is driven by a low voltage source. The relay comprises a main coil and a first armature cooperating with the main coil, wherein a coil current of the main coil is powered by the low voltage source, and the first armature is located in the high voltage circuit in a corresponding position to disconnect or close the high voltage circuit in response to power off or power on of the main coil; a secondary coil cooperating with the first armature and a drive circuit for supplying power to the secondary coil, wherein the drive circuit is powered by a high voltage source of the high voltage circuit, and the secondary coil regains power as the secondary coil is closed, thereby generating additional electromagnetic force to put the first armature into a closed position; and a second armature cooperating with the main coil, wherein the second armature is located in the drive circuit and in a corresponding position to disconnect or close the drive circuit in response to power off or power on of the main coil. The present invention also provides a power battery circuit using the relay.

La présente invention concerne un relais pour un circuit haute tension. Un commutateur du relais est excité par une source basse tension. Le relais comprend une bobine principale et une première armature coopérant avec la bobine principale, un courant de bobine de la bobine principale étant fourni par la source de basse tension, et la première armature étant située dans le circuit haute tension dans une position correspondante pour déconnecter ou fermer le circuit haute tension en réponse à la mise hors tension ou à la mise sous tension de la bobine principale ; une bobine secondaire coopérant avec la première armature et un circuit d'attaque pour fournir de l'énergie à la bobine secondaire, le circuit d'attaque étant alimenté par une source de haute tension du circuit haute tension, et la bobine secondaire récupérant de l'énergie lorsque la bobine secondaire est fermée, générant ainsi une force électromagnétique supplémentaire pour placer la première armature dans une position fermée ; et une seconde armature coopérant avec la bobine principale, la seconde armature étant située dans le circuit d'attaque et dans une position correspondante pour déconnecter ou couper le circuit d'attaque en réponse à la mise hors tension ou à la mise sous tension de la bobine principale. La présente invention concerne également un circuit de batterie d'alimentation utilisant le relais.
