The device for realizing automatic meter reading under the condition of transformer power failure further comprises a power failure detection module 9, a standby power supply module, a first electric control switch 12 and a control device 13. The power failure detection module 9 is electrically connected with the low-voltage line 2 and used for detecting whether the low-voltage line 2 is electrified or not. The standby power supply module is used for providing electric energy. The standby power supply module is electrically connected with the meter front circuit 4 through the first electric control switch 12.

Specifically, when the low-voltage line 2 is electrified, the solar panel 11 charges the storage battery 10, and the residual capacity of the storage battery 10 is ensured to be greater than 80%; when the low-voltage line 2 is not charged, the solar panel 11 stops supplying power to the storage battery 10, and the storage battery 10 supplies power to the control device 13 and the meter front line 4 respectively. The control device 13 is also responsible for managing charging and discharging of the battery 10.

thirdly, when the power failure detection module 9 detects that the voltage of the low-voltage line 2 is zero, the control device 13 firstly switches off the air switch 3, then switches off the second electric control switch, and finally switches on the first electric control switch 12, so that the storage battery 10 provides electric energy required by communication with the server 8 for the electric energy meter 5 and the negative control terminal 7;
after the transformer 1 recovers power supply, the power failure detection module 9 detects that the low-voltage line 2 has voltage, the control device 13 controls the first electronic control switch 12 to be switched off, then the air switch 3 and the second electronic control switch are sequentially switched on, and the transformer 1 provides electric energy required by communication with the server 8 for the electric energy meter 5 and the storage battery 10.
