Technical Field

[0001] The utility model relates to the technical field of power distribution boxes, in particular to an intelligent lock for a power distribution box. Background Art

[0002] The distribution box is a massive parameter in data. It is generally composed of low-voltage electrical wiring. It requires the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. At the same time, when the distribution box is in use, it needs to be matched with a smart lock to effectively protect the distribution box.
