摘要:
由于配网线路耐雷水平低,网络结构复杂,常常遭到直击雷和感应雷过电压的影响,导致线路跳闸和设备损坏,给电网运行安全带来极大的风险。为解决配电线路雷击跳闸的问题,研究了一种压缩灭弧防雷间隙:通过有效的绝缘配合使得雷电闪络能够准确地控制在设定的防雷间隙之中,利用雷电冲击电弧自身的能量进行压缩,产生“磁抽吸”效果使得大量气体被吸入压缩管道,在压缩管道内温度瞬间上升产生自膨胀气流,加速电弧突变拐点的能量耗散,使得电弧能在电力系统继电保护装置最快动作时间之前有效地熄灭。本文建立了灭弧过程中最为关键的压缩、温升、对吹模型; 在冲击电弧实验中,示波器的波形有效地证明压缩灭弧装置可以对冲击电弧进行能量分段并截断电弧; 在工频电弧实验中,通过与普通并联间隙的灭弧效果比较,发现压缩灭弧装置可以使工频电弧电压波形衰减周期更快、幅度更大,装置可以在1 500 μs内对2 kA的工频电弧进行截断并且熄灭。压缩灭弧防雷间隙在35 kV配电线路运行效果良好,能够有效地降低配电线路的雷击跳闸率。
Abstract:
Due to the low lightning resistance level and the complex network structure, the distribution network is often affected by direct lightning strikes and lightning overvoltage, resulting in line tripping and equipment damage, which brings great risks to the safe operation of the power grid. In order to solve the problem of lightning strikes on distribution lines, a compression arc extinguishing lightning protection gap was studied. It is through the effective insulation and coordination that the lightning flashover can be accurately controlled in the set lightning protection gap, through the lightning impact of the arc's own energy to compress, produce a “magnetic suction” effect so that a lot of gas is sucked into the compression pipeline, the self-expansion air flow is generated in the instantaneous increase of the temperature inside the compression pipeline, accelerating the energy dissipation at the inflection point of the arc mutation, so that the arc can be effectively extinguished before the fastest action time of the power system relay protection device. The most critical compression, temperature rise and blow-off models in the arc extinguishing process are established; then the impulse arc test is performed, and the waveform of the oscilloscope effectively proves that the compression arc extinguishing device can perform energy segmentation on the impulse arc and cut off the arc; The power frequency arc test is conducted. By comparison with the arc extinguishing effect of the common parallel gap, it is found that the compression arc extinguishing device can make the periodical attenuation waveform of the power frequency arc voltage faster and the amplitude larger. The device can cut off and extinguish 2 kA power frequency arc in 1 500 μs. The compression arc-extinguishing and lightning-protection gaps have good effect on the 35 kV distribution line and can effectively reduce the lightning strike rate of the distribution line.
