In the modern energy supply system, overhead transmission lines span mountains and rivers, traverse villages and towns, and shoulder the important responsibility of sending electricity from power plants to thousands of households and industrial enterprises. However, due to long-term exposure to the open air environment, transmission lines continue to suffer from nature's assault, the sun, wind and rain, low temperature ice and snow, as well as the complexity of the changing geographic environment, which also led to all kinds of faults occur from time to time.
As the transmission line distance is long, across different management units, based on this, I have prepared this very practical overhead transmission line fault diagnosis and location guide.
developed and produced Transmission Line Faults.Transmission Line Fault Monitoring System (Distributed Fault Diagnosis Device)DX-WPS100-GZ01 is generally applicable to the analysis and positioning of tripping faults, lightning strikes and other faults on power lines of 35kV and above voltage levels, specifically through the unfolding of the transmission line disturbance sensing, to realize the abnormal diagnosis of the transmission line, analyze and locate the fault location points with high precision.
Working Principle
Contact distributed fault diagnostic device is distributed and installed on one side of transmission conductor, collecting traveling wave current signal and industrial frequency signal at the moment of fault at high speed, with the continuous recording of traveling wave current ≥1000μs, and sending the data back to the backstage data center through the communication module to carry out the automatic positioning of the fault location, analyzing the cause of the fault, and sending the diagnostic results to the operation and maintenance personnel in the form of WEB, SMS and so on.
Installation Cases
Our Distributed Fault Diagnostic Device is fully qualified, functionally stable, and meets the technical requirements of the State Grid South Network.
Distributed Fault Diagnostic Device is fully qualified, functionally stable, and meets the technical requirements of the State Grid South China Network. In addition to contact distributed fault diagnosis, we also provide non-contact fault diagnostic device, high-voltage cable fault and hidden danger monitoring system, distribution network traveling wave fault location device and a series of transmission and distribution substation online monitoring and fault location solutions and equipment.
