33、缘子并联间隙试验等实验室试验，并进展试验室数据分析，旨在根据相关分析找出影响不同绝缘子、绝缘导线、间隙等防雷的主要因素，进而针对这些主要因素提出防雷措施。通过实验发现，绝缘子使用U50%放电电压高的绝缘子有利于提高线路的绝缘水平，增强配电线路的耐雷水平；绝缘子的积污在雷雨情况下，将会造成线路的绝缘水平的下降；绝缘子击穿电压与绝缘长度大致符合线性关系，绝缘长度一般取177mm 为最优；在一样湿度下，枯燥绝缘子的击穿电压U50%要比潮湿绝缘子击穿电压U50%高得多；在绝缘子湿度达到一定程度后，湿度本身已不是绝缘击穿的主要因素。绝缘导线的击穿均发生在距离绝缘子轴线200mm 以内，因此，只要在这个X
34、围内加强绝缘导线的防雷措施，尤其是接点处的绝缘，根本可以预防雷击断线。并联间隙与导线的种类无关，即不论是裸导线还是绝缘导线，在绝缘子型号不变的情况下，间隙的距离也不会改变，与绝缘子并联间隙的距离与绝缘子的冲击放电电压有关。关键字：10KV配电线路；绝缘子；绝缘导线；并联间隙；防雷措施文档编码:CR5A3V10Y7R2 HH8U8U7Z9R5 ZA7M7V2J1N6文档编码:CR5A3V10Y7R2 HH8U8U7Z9R5 ZA7M7V2J1N6文档编码:CR5A3V10Y7R2 HH8U8U7Z9R5 ZA7M7V2J1N6文档编码:CR5A3V10Y7R2 HH8U8U7Z9R5 ZA7M7

41、A7M7V2J1N6word 0/33 第一章绪论1.1 课题研究的目的和意义配电线路直接面向广阔电力用户，其供电的安全性和可靠性事关重大。10kV 配电网络结构复杂、绝缘水平低，不管直击雷还是感应雷，均能造成雷害事故。有关数据统计，在635kV电网中，雷击跳闸率居高，且经常有柱上开关、避雷器、变压器、套管等设备在雷电活动中损坏，在雷电活动强烈时，有的配电站所有10kV线路全部跳光。经过电网改造之后，在雷电活动密集的地区，雷害事故依旧时有发生，极大地影响了电网的供电可靠性和运行安全性。所以，本文的目的是对配电线路保护现状进展认真分析和研究，找出雷害事故的主要原因，改良和完善防雷措施。国内外研究
42、现状水平综述随着地区经济的开展，人们对电能的依赖越来越强，对供电可靠性的要求越来越高。配电网绝缘水平低，雷害事故时有发生，随着科学技术的开展，研究更安全、更环保、更廉价的防雷技术和防雷材料成为迫正在眉睫的问题。10KV 配网中主要有两种接地方式，即中性点非有效接地系统 中性点经消弧线圈接地也属于这一种和中性点经小电阻接地系统。目前，针对于10KV 配电线路的防雷技术有：安装避雷器、降低杆塔的接地电阻、装设自动重合闸装置、架设避雷线、使用消弧线圈等。1.2.1 安装避雷器根据以往经验，线路避雷器在线路防雷过程中有很好的效果，特别是在 10KV 配电线路的绝缘薄弱的地方，最好安装避雷器。随着配电线
43、路绝缘水平的不断提高，从性价比方面考虑，在线路上不在等间距大量安装避雷器。但是在一些特殊部位必须安装加以保护。1安装在有配变的的地方，兼做变压器保护；2为防止开路反射，假设柱上断路器没安装避雷器，在电源侧曾壮一组避雷器；3在转角杆角度小于 100度的杆处加装一组避雷器；4在大跨越档档距大于 500M 的两侧杆塔上各装设一组避雷器；510KV 线路交叉档两侧加装一组避雷器，防止不同电压等级线路出现交叉跨越事故。11.2.2 降低杆塔的接地电阻在配电线路中，降低杆塔的接地电阻的方法有：1采用用于降阻的水平接地体方法。不过接地体易腐蚀，降低使用年限；2利用降阻剂进展降阻。在水平接地体的周围世家搞笑膨
44、润土降阻防腐剂，不仅效果明显，而且性能稳定、不易腐蚀。21.2.3 装设自动重合闸装置线路遭受雷击后，存在雷电闪络，产生工频电弧使相间短路，断路器跳闸。在电弧熄灭后，应该立即恢复供电。为此，在多雷区的10KV 配电线路中尽量安装重合闸装置，提高供电可靠性。1.2.4 架设避雷线架设避雷线可有效地防止直击雷；对于感应雷，由于避雷线的屏蔽效果，可以抑制骑在相导线中产生的过电压。如果导线高度为10M,导线间距为 0.7M,设雷击点距离导线 50M,雷电流幅值为 500KV,装设一根架空地线,平均高度为 11M,如此感应雷过电压最大值可降低为文档编码:CR5A3V10Y7R2 HH8U8U7Z9R5
