POWER SUPPLY APPARATUS |
| 摘要 |
A battery power supply device includes an alternating-current power source, a secondary cell connected to the alternating-current power source, a first switch for selectively connecting or cutting off a cell and the alternating-current power source, the first switch being disposed between the battery and the alternating-current power source, and a ground fault sensing device for sensing a ground fault in the battery, the ground fault sensing device being connected closer to the battery than the first switch; the ground fault sensing device sensing a ground fault in the battery when the first switch is off. |

1. A power supply device comprising:
an alternating-current power source; a secondary cell connected to the alternating-current power source; a first switch configured to selectively connect or turn off the secondary cell and the alternating-current power source, the first switch being disposed between the secondary cell and the alternating-current power source; and a ground fault sensing device configured to sense a ground fault in the secondary cell, the ground fault sensing device being connected closer to the secondary cell than the first switch, the ground fault sensing device configured to sense a ground fault in the secondary cell by sensing a reduction in insulation of the secondary cell when the first switch is off. |
