查询词典 lightning conductor

Results show that the lightning channel is a good conductor, and electrons are the main carrier of channel current.

结果分析得出：闪电通道是良导体，电子是通道电流的主要载体；一般情况下，人工触发闪电的通道亮度比自然闪电通道大，而通道回击电流小于自然闪电。

The influence of lightning, UHV bundle conductor configuration and high operating voltage were considered in the model.

考虑到雷电背景、特高压线路的多分裂导线结构和高运行电压，建立分析特高压线路分裂导线表面连续上行先导起始的数值仿真模型。

Shanghai bochi electrical technology limited company sets up in 1999, is specialized is engaged in the thunder and lightning protection, the conductor connection and the communication product research and development and the production processing, simultaneously acts the overseas well-known brand product company.

上海博驰电气技术有限公司组建于1999年，是一家专业从事雷电防护、导体连接及通讯产品的研发和生产加工，同时代理国外知名品牌产品的公司。

It is not reasonable that striking distances of lightning leader to phase conductor, ground line and the ground are equal in classical electric geometry method.

针对经典电气几何模型认为雷电先导对导线、避雷线、大地三者之间击距相等的不合理问题，提出了用击距系数来描述雷电先导对导线与大地击穿强度的差别；依据长间隙放电与雷击放电的相似性，开展了棒-板间隙实验以得到击中目的物概率为50%时雷电先导与地面、导线之间的位置关系。

In the striking distance factor model, randomicity of progression for up leader and down leader is ignored, and the critical striking electric intensity of lightning leader to phase conductor and ground are both decided to 500kV/m. This suppose is not proper.

击距系数模型忽略了上下行先导发展的实质，将先导对地与对导线的临界击穿强度均取为500kV/m，这种假设不合理。

Conductor lightning eliminator ; lightning rod ; optimum number of a needle

导体消雷器；避雷针；最佳针数
