The following is the main points . haishrwan - jmchang - jiayuguan 330kv extra high voltage transmission lines is the weak line in gansu 本文研究的主要内容如下：海石湾金昌嘉峪关330kv超高压输电线路是甘肃电网中的薄弱环节。
The paper studies the relation between the ehv transmission line and the human health by calculating method based on the present research achievements 本文通过理论计算的方法，在总结现有研究成果基础上，研究了超高压输电线与人类健康的关系。
Recently , people pay more and more attention to the biological effect of the electromagnetic field ( emf ) caused by the ehv transmission line to the health of human 近来，超高压输电线产生的工频电磁场的生物效应对人类健康的影响愈来愈引起人们的重视。
It is the conclusion that the heat absorbed by human body is too small to cause the thermal hurt to human under the present ehv transmission line in our country 研究表明，在我国现有的超高压输电线路下，人体所吸收的能量很小，因此从热效应方面看不足以对人造成伤害。
This paper studies the safety of the biological effect of the ehv effect by calculating the emf distribution in human body , and gets some theoretical and actual conclusions 本文通过计算人体内电磁场分布的方法，研究了超高压输电线生物效应的安全性，得出一些具有理论和实际意义的结论。
According to the environmental and medical reports , associating to th e safety criteria and test results , comparing with the calculating results , the paper studies the relation between the ehv transmission line and human health 根据环境和医学方面的研究报告，结合相应的安全标准和实验结果，对照计算结果，分析了超高压输电线与人类健康的关系。
This paper analyzed the types of obstacles of super - high voltage transmission line , and a kind of new typed configuration , which could stride over the obstacles on the transmission line , of double armed autonomous obstacle surmounting and touring inspection robot was put forward 分析了超高压输电线路障碍物的类型，提出了一种新的双臂自主越障巡检机器人构型，该构型能够跨越输电线路上的障碍物。
In order to avoid the ehv system disaster caused by reclosing on the permanent fault of transmission line , adaptive autoreclosure based on microprocessor - based protection arises at the historic moment , but is still in the stage of theory study 为了避免超高压输电线路采用自动重合闸时重合于永久性故障所造成系统稳定破坏等重大系统灾难，在微机保护的基础上，自适应重合闸应运而生，但尚处于理论探索阶段。
Based on the results , the article analysis the main factors : the voltage level and the current of the line , the height of the line , the distance between two phases , the structure and the location of the lines , that affect the distribution in human body , and gets some basic principles 根据计算结果，分析了超高压输电线的电压等级、电流、离地高度、导线的相对位置结构和距离等影响人体内电磁场分布的主要因素，得出一些基本规律。
