Title:
CURRENT INTERRUPTION DEVICE AND CURRENT INTERRUPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/054338
Kind Code:
A1
Abstract:
Provided is a current interruption device equipped with: a current limiting element that is provided in a power supply path from a predetermined power source to a load device and exerts a current limiting action if a current flowing through the power supply path exceeds a first current threshold; a commutation path switch capable of on/off switching of electric conduction in a commutation path connected in parallel to the power supply path; and a control unit that controls on/off of the commutation path switch. The control unit switches the commutation path switch from off to on when detecting that the current flowing to the current limiting element has been limited to a second current threshold after exceeding the first current threshold, and switches the commutation path switch again to off when a predetermined switch-on maintaining time has elapsed since the commutation path switch was switched to on.
