Transmission lines face a variety of fault challenges.
Spring, everything is recovering, humid air combined with bird nesting feces / industrial dust and other external interference, resulting in frequent insulator flash faults, at the same time, windy weather may also lead to line dancing, foreign objects hanging line and other issues; summer, lightning activity is frequent, lightning strikes become one of the important reasons for transmission line tripping, heavy rainfall may also trigger landslides, flooding scouring of the base of the tower, and other geologic hazards; fall humidity drops greatly! In the fall, the humidity may drop from 90% to 30%, and the dry climate makes the trees yellow and the risk of hill fires increases; in winter, the cold temperature will make the conductor contraction, ice-covered phenomenon occurs from time to time, and the over-heavy ice-covered towers may be overwhelmed, pulling off the conductor, causing large-scale power outages.
In the face of these complex and changing types of faults, Shenzhen Dingxin Wisdom Technology's < strong>Transmission Line Abnormal State Intelligent Diagnostic Device (contact type) stays at its post in all seasons and plays a key role in keeping power supply.
Transmission line abnormal state intelligent diagnostic device (contact) installed in the transmission line conductor, not subject to corona and other harsh electromagnetic environment, in the strong electric field environment, to realize the transmission line fault voltage, electric pop wave and the collection of industrial frequency voltage, current, whether it is the peak period of the electric power of the high-current conditions, or low load hours of the small current situation are not in question.
Transmission line abnormal state intelligent diagnostic device (contact) each set of devices to monitor the range of at least up to 30 kilometers, no longer need to install equipment on each base tower, to ensure that it will be able to record data in real time, accurately and wirelessly sent to the background central station. ;
In addition, the device also has the function of automatically recording high-precision GPS/BD clock with an error of ≤0.1μs, which makes the result of fault diagnosis more accurately trace the process of fault occurrence and find out the root cause of the fault, and it is generally applicable to 35kV-1000kV AC transmission lines to play the role of distributed fault localization in transmission networks of different voltage levels.
