计算了不同雷电流的感应雷电压值。研究了氧化锌避雷器、穿刺型防雷金具、可调式保护间隙和采用绝缘塔头及横担的防雷保护原理。运用ATPDraw软件仿真标准雷电压在配电网中引起的感应雷过电压波形

比较了防雷金具与防弧金具的优劣

针对不同绝缘子的保护间隙做了相关击穿性试验。分析表明

根据不同的配电环境和要求

合理选择其中的一种或几种相结合的防雷措施可以有效地降低架空绝缘导线的雷击故障率

从而为10 kV配电网的防雷提供了参考。

Abstract

The reasons of 10 kV distribution network easily hit by lighting and the mechanism of lighting-caused breaking are analyzed in this paper.The corresponding induced over-voltage value is calculated under different lightning current.ZnO arrester

puncturing lightning protection hardware

adjustable protection-clearance and insulate tower top and cross arm are researched for the principle of lightning protection.ATPDraw software adopted to simulate the induced over-voltage in distribution network

which resulted by standard lighting.It compares advantage between lighting protection hardware and arc.Some breakdown experiments are done to test protection-clearance for different insulators.The analysis shows that rationally selecting one or several combined of lighting protection measures for different environment and requirements is able to reduce the failure of overhead insulated conductors

and could provide reference for lighting protection of 10 kV distribution network.
