[0001] This application relates to the field of intelligent device box technology, specifically to an intelligent device box with integrated reclosing function. Background Technology

[0002] With the development of information technology, intelligent video surveillance equipment boxes have become widespread in society and daily life. Video surveillance is widely used for management in highways, urban traffic, public places, intersections, village entrances, and other locations. Automatic reclosing, with its overvoltage, undervoltage, short circuit, and overload protection functions, has become a crucial component of intelligent equipment boxes.

[0003] Currently, the automatic reclosing function of smart device boxes is external and requires independent installation. This is not conducive to later maintenance, modification and installation. It is equivalent to adding an external device, which does not meet the requirements of integration and increases costs. Utility Model Content

[0004] In view of the above problems, this application provides an intelligent equipment box that integrates reclosing function, which solves the problem that the automatic reclosing function of existing intelligent equipment boxes needs to be installed externally, which is not conducive to later maintenance, modification and installation, fails to meet the requirements of integration, and increases costs.

[0005] To achieve the above objectives, the inventors provide an intelligent device box integrating reclosing function, comprising:

[0006] Power input connector;

[0007] A leakage current unit, wherein the power input terminal of the leakage current unit is connected to the power output terminal of the power input connector;

[0008] A power acquisition unit, wherein the power input terminal of the power acquisition unit is connected to the power output terminal of the power input connector, and the signal input terminal of the power acquisition unit is connected to the signal output terminal of the leakage current unit;
