Auxiliary device for regular inspection of spare power automatic switching device

The invention discloses an auxiliary device for regular inspection of a spare power automatic switching device. The auxiliary device comprises a plurality of analog switches, an input loop module, a 24V direct-current power supply module, a first pluggable connecting piece, a second pluggable connecting piece and a third pluggable connecting piece. First connecting ends of the plurality of analogswitches are connected with the first pluggable connecting piece. Second connecting ends of the plurality of analog switches are connected with the second pluggable connecting piece. Third connectingends of the analog switches are connected with a first connecting end of the switch loop module. A second connecting end of the switch loop module is connected with the third pluggable connecting piece. The 24V direct-current power supply module is used for providing a required working power supply for the analog switches and the input loop module. The auxiliary device can adapt to spare power automatic switching devices o
