The invention discloses an ATM protection cabin self power supply device based on a vertical-axis wind generator set. The ATM protection cabin self power supply device comprises a device body and a power control circuit. The device body comprises a protection cabin body, a protection cabin door, a socket, and a vertical-axis wind generator set which is arranged on the top of the protection cabin body. The power control circuit comprises a transformer, a battery pack and a power switching module. The output end of the vertical-axis wind generator set is connected with the transformer. The output end of the transformer is connected with the battery pack. The output end of the battery pack is connected with a first input end of the power switching module. A second input end of the power switching module is connected with the socket. The output end of the power switching module is connected with an ATM protection cabin. The standby battery pack is charged by the high-efficiency vertical-axis wind generator set in order to prevent the situation in which the ATM protection cabin is powered off and causes property and life losses to depositors. The ATM protection cabin self power supply device has the advantages of resource saving, high reliability, and the like.
