不同类型电缆耦合雷电感应过电压研究
|
摘要
针对电力线缆和通信线缆感应雷电过电压的问题,利用多脉冲雷电流发生器模拟自然雷电,对架空线缆进行耦合试验,分析雷电流泄放时产生的瞬态雷击电磁脉冲在不同类型线缆上耦合的感应过电压特征和差别。试验结果表明,多脉冲下线缆中耦合的电压波形分布的数量和时间间隔同多脉冲冲击源的变化分布相一致,对于多脉冲中的单个脉冲波形,线缆上耦合的雷电过电压波形形式是一种阻尼振荡,震荡周期为微秒级。随着冲击雷电流的增大,线缆内耦合的雷电感应过电压呈增大趋势,不同类型线缆耦合的感应电压存在较大差异,敏感程度顺序为电话线>高压线>三相电源线>有线电视线。增加屏蔽措施以后,耦合电压最大可衰减80%。
For power cable and communication cable induction lightning overvoltage problem,using multiple pulse generator simulating natural lightning,overhead cable coupling test was carried out,analysis of lightning current discharge during transient lightning electromagnetic pulse coupling of the induced over-voltage on different types of cable characteristics and differences. Test results show that: in the cable under the multiple pulse coupled voltage waveform distribution and the number of time interval distribution is consistent with the changes in the impact pulse source,for single pulse waveform of multiple pulse,cable on the coupling form of lightning overvoltage waveform is a damped oscillation,oscillation cycle for mu s level.,with the increase of impact lightning current cable coupling in lightning induced over-voltage showed a trend of increase,There are significant differences in the inductive voltage of different types of cable coupling,sensitive degree sequence for the high tension line telephone line > high voltage line > three-phase power line > cable line of sight. After increasing the shielding measures,the maximum coupling voltage can be reduced by 80%.
