Power grid fault detection system

Abstract

The invention discloses a power grid fault detection system comprising a server end module, a self-check module and a monitoring mobile module, wherein the self-check module comprises a fault detectorarranged on a power grid branch line and a communication terminal connected with the fault detector, the fault detector is used for sending fault signal comprising information of the branch line whena preset fault current on the power grid branch line is detected, and the communication terminal is used for sending the fault signal to the server end module; the monitoring mobile module comprisesa WeChat module and an information sending module; the WeChat module comprises an image collection unit which is used for obtaining image information of the power grid branch line, the information sending module is used for sending the image information obtained via the image collection unit to the server end module, and the power grid fault detection system is advantaged by high detecting effectsand capability of timely detecting fault points.

Description

technical field [0001] The invention relates to a fault detection system, in particular to a power grid fault detection system. Background technique [0002] With the rapid development of power technology, users' requirements for power supply reliability of power distribution network are also increasing. At present, most of the distribution network systems in various regions are non-grounded systems. When some high-resistance grounding short circuits and hidden faults occur, it often leads to vicious large-scale power outages caused by the tripping of the upper-level substation, making the entire distribution network system Power supply reliability is low. And then cause greater economic losses to local residents and industrial and commercial enterprises. [0003] Usually, in the prior art, the fault points are manually checked one by one, but the above method of determining the location of the fault points needs to consume a lot of manpower and material resources, and the...

At present, most of the distribution network systems in various regions are non-grounded systems. When some high-resistance grounding short circuits and hidden faults occur, it often leads to vicious large-scale power outages caused by the tripping of the upper-level substation, making the entire distribution network system Low power supply reliability

In turn, it will cause greater economic losses to local residents and industrial and commercial enterprises.

[0003] Usually, in the prior art, the fault points are manually checked one by one, but the above method of determining the location of the fault points needs to consume a lot of manpower and material resources, and the efficiency is low
