A compressed arc extinguishing device for power distribution network is developed to solve the problem of existing anti-lightning of power distribution network transmission lines. This paper first introduces the arc extinguishing principle of the arc extinguishing device, and then designs the lightning impulse voltage test around the 10 kV transmission line. The test results show that the U50% Lightning impulse voltage of the arc extinguishing device is 112.4 kV considering the atmospheric correction factor. In order to verify the feasibility of the arc extinguishing device, the power frequency continuous current interruption test is designed. The test shows that the arc extinguishing device can extinguish the arc with a peak value of 1.131 kA in 2 ms and does not reignite in the following time. Finally, the device is applied to a 10 kV power distribution network transmission line of China Southern Power Grid. The lightning trip-out rate of the transmission line per 100 km is reduced from 12.5 (times/year) to 1.1 (times/year), which fully verifies the feasibility of the arc extinguishing device. © 2021 Institute of Electrical Engineers of Japan.

配电网压缩灭弧装置的实验研究

为了解决配电网输电线路现有的防雷问题,研制了一种配电网压缩灭弧装置。本文首先介绍了灭弧装置的灭弧原理,然后设计了10 kV输电线路周围的雷电冲击电压测试。测试结果表明,U 50%考虑到大气校正因子,该消弧装置的雷电冲击电压为112.4kV。为了验证灭弧装置的可行性,设计了工频连续电流中断试验。测试表明,该消弧装置可在2毫秒内熄灭峰值为1.131 kA的电弧,并且在接下来的时间不会再点燃。最后,将该装置应用于南方电网的10 kV配电网输电线路。每100 km输电线路的雷击跳闸率从12.5(次/年)降低到1.1(次/年),充分验证了灭弧装置的可行性。©2021日本电气工程师学会。由Wiley Periodicals LLC发布。
