The invention discloses a low-voltage release reset device which comprises a switch power supply circuit, a driving circuit, a motor and an execution mechanism, wherein the switch power supply circuitis used for converting alternative-current voltages into a first direct-current voltage and a second direct-current voltage and used for outputting the voltages; the driving circuit is connected withthe output end of the switch power supply circuit and is used for outputting driving signals for driving the motor to rotate forwards or backwards according to provided direction control signals; themotor is connected with the output end of the driving circuit and is used for driving the execution mechanism to move according to the driving signals to be connected or disconnected with a release.By adopting the low-voltage release reset device, driving signals for controlling the motor to rotate forwards or backwards are output through the driving circuit according to provided direction control signals, the execution mechanism is driven to move, and then remote connection or disconnection of the release can be achieved.
