Distribution transformers are frequently damaged by lightning stroke in China,

我国配电变压器雷击损坏比较普遍,特别在湿热带多雷地区尤为显著。1974年,我校“配变防雷”研究小组首次提出Y/Z_0配变的防雷性能比Y/Y_0配变好的观点。Y/Z_0配变适合用于多雷地区。本文论述了在一定的接地电阻下变压器、避雷器组合大冲击电流试验的结果,并且确定了Y/Y_0和Y/Z_0配变的实际耐雷水平。研究表明,模拟试验,大冲击电流试验和分析计算的结果是非常一致的。

In this paper,the method of successive approximation of spheric image is applied, and a simple programme for microcomputer is used to calculate electric field in space produced by thundercloud, so the charge model used before can be replaced by the spheric distribution model of thundercloud. the field in space may be calculated more exactly.

本文应用电磁埸理论中的球镜象逐次逼近法,建立能在微机上计算的较简单的程序,并将其应用于雷雨云产生的空间电埸的计算。这样可用雷云的球模型代替过去的点电荷模型,使雷云的空间电埸计算具有更高的精度。对不受空间电埸影响的埋地电缆和石油、天然气管道,本文将应用电磁埸理论分析雷击放电地中电流的电磁干扰,从而探讨通讯机、计算机及石油管道阴极保护等电子设备在具有防雷设施时仍遭雷击损坏的原因。

This Paper discusses the operration of rural low-voltorge network with neutral ungrounded,it may be reduced the shock current and a lot of fatal accidents.At the same time it can suppress the overvoltorge which superposed by normal or in- verse transformation of lightring surge in transformer winding and lower the fau- lts of transformers and meters.The results of calculation,analysis and operation indicate that it can be taken as a safety measures in rural electrie supply.

本文讨论了低压中性点不接地运行,可以减少人体融电电流,因而大幅度减少触电死亡;同时它抑制正、逆变换过程的雷电过电压,可以减少雷击损坏变压器和电度表。计算分析和运行结果表明,它可以作为农村安全用电措施。
