[0027] Compared with the prior art, the present invention provides an intelligent monitoring system for distribution network operation and maintenance, which has the following beneficial effects:

[0028] 1. This intelligent monitoring system for power distribution network operation and maintenance, through the installed pole tilt monitoring unit, monitors the tilt angle data of power distribution poles in real time during use. The pole angle acquisition module collects the data of the poles, and the data analysis and processing module calculates the tilt state of the poles. After filtering the angle changes and eliminating the swaying caused by strong winds or other factors, it determines whether the pole is tilted, thereby avoiding the overturning accident caused by the tilting of the poles.

[0029] 2. This intelligent monitoring system for power distribution network operation and maintenance, through its set-up power distribution network temperature monitoring unit, monitors the temperature data of cables, joints, and disconnectors during operation via cable joint temperature data acquisition modules and disconnector joint temperature data acquisition modules. When faults occur in substation outgoing line cabinets, transformers, branch cables, joints, and disconnectors, or when lines are overloaded, causing temperatures to rise above the ambient temperature by more than 10ºC, the system accurately locates and alarms the fault. Navigation via a mobile app allows for timely arrival at the fault location and accurate repair, preventing further faults. The system is set to automatically alarm and locate the fault when the temperature value is ≥60ºC, facilitating timely repair.

[0030] 3. This intelligent monitoring system for power distribution network operation and maintenance, through the set-up box door status monitoring unit, monitors the opening and closing status of the box door during use through the box door monitoring data acquisition module, realizes the alarm for abnormal opening of the box door, and prevents human damage and misoperation.

[0031] 4. This distribution network operation and maintenance intelligent monitoring system, through the set distribution substation grounding resistance monitoring unit, monitors the grounding resistance value of the distribution substation during use through the grounding resistance data acquisition module. This prevents damage to user equipment caused by excessive grounding resistance, grounding wire breakage, or abnormal power supply voltage quality. The real-time and accurate monitoring of grounding resistance value through intelligent operation and maintenance tools enables timely alarm and handling.

[0032] This intelligent monitoring system for power distribution network operation and maintenance, through its data processing unit and APP connection unit, processes the collected data in real time during use, monitors and stores the data, and binds it to the mobile APP, thereby enabling more convenient and accurate location of operation and maintenance faults and timely alarm and rapid handling.
