ABNORMALITY DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/095412
Kind Code:
A1
Abstract:
An abnormality detection device (10) is for use in a supply system which comprises a power supply unit (90), and a first power line (92) and a second power line (93) that are provided between the power supply unit (90) and a pyrotechnic disconnect (91). The abnormality detection device comprises: a first switch (10A) for the first power line (92); a second switch (10B) for the second power line (93); a first resistor unit (10C) and a second resistor unit (10D); and a detection unit (10E). The first resistor unit (10C) is electrically connected to a first site (B1) between the power supply unit (90) and the first switch (10A) and to a second site (B2) between the second switch (10B) and the pyrotechnic disconnect (91). The second resistor unit (10D) is electrically connected to the second site (B2) and to a third site (B3) between the second switch (10B) and the power supply unit (90). The detection unit (10E) detects a voltage state at the second site (B2) at a time when the first switch (10A) and/or the second switch (10B) is in an off-state.
