One step, two steps, three steps, four steps, looking at the sky, such a scene seems to put people in a romantic scene. However, when we turned our attention to the inspection of power lines, this romance disappeared in an instant.
Inspecting power lines is not an easy task, and it requires workers to wade through mountains and rivers, through jungles, and even climb high mountains. Recently, the impact of ice disasters has also made it more difficult to inspect power lines. There are also many power lines due to the impact of icing and short-circuiting, grounding and other faults, resulting in frequent power outages. This not only brings inconvenience to people's lives, but also has a certain impact on the operation of the whole society.
Due to the actual environmental factors, the efficiency of inspection is also greatly reduced, so let's take a look at the scheme of the distribution network fault location device.
Distribution network fault location device scheme:
If you don't miss any detail, you can only look at the 'traveling wave measurement', which has a wide range of applications in physics, electronic engineering and communication. A traveling wave is a form in which a wave propagates through a medium and has a specific amplitude, frequency, and phase. These attributes remain unchanged with the propagation of the wave, forming the characteristics of the traveling wave, based on this, the distribution line fault location device (distribution network line fault warning and positioning device) appeared, the equipment through real-time monitoring of the line insulation defects caused by the periodic high-frequency discharge signal to the ground, the collection of high-frequency discharge waveform data, can judge the type of fault in real time, locate the specific occurrence point of the fault, and return the early warning information, so that the inspection "twice the result with half the effort"!
