输电线路工频磁场输电线路工频磁场magnetic field of transmission line元件通以电流时，则会在元件与磁通、电流均互为垂直的方向上感生出霍尔电压。根据该电流、电压及其他相关参数便可算出相应磁场的磁感应强度大小。可用一旋转矢t来表示。矢t的大小和方向随时间的不同而改变，它在某一方向有一最大值，垂直于最大值方向有一最小值。该矢t的旋转轨迹为一树圆，一般用与最大磁感应强度B.:及最小磁感应强度B‘成比例的两个矢t来表示。磁感应强度又称磁通密度。工程上常用磁感应强度的垂直分t和水平分t来表征空间某点的工频磁场.根据对不同电压等级输电线路工频磁场的实际侧t，获知500 kV输电线路线下地面附近的磁感应强度仅为。.05mT，而彩色电视机或电炊事用具附近的磁感应强度约为0.5~1.omT，所以一般认为愉电线路线下地面附近的磁场不致对人身产生生态影响.但在与输电线路平行的伸长形导体上(如对地绝缘的金属橱栏、电信线、广播线、对地绝缘的金属管道等)，会因工频磁场的作用产生沿线路方向的感应电动势。当这些伸长形导体的一端接地，人接触另一端或距接地端一定距离接触该导体时，导体上的感应电动势将通过人体和大地形成回路，会由此产生电击。防止的方法是将这类伸长形导体两端和中部接地。屏蔽工频磁场要比屏蔽工频电场困难得多，原因是工颇磁场很容易穿透大多数物体如建筑物等，而且磁场中的物体对磁场的崎变比对电场的崎变要小。输电线路磁场计算计算愉电线路工频磁场和计算辅电线路工频电场的方法类似，可用镜像电流来代替地中的分散电流，所不同的是镜像电流的位!一般距地面很深，其深度d由下式决定，即J一。60存，m式中P为大地电阻率，nm;f为交流电频率，H:。由于镜像电流很深，故在很多情况下可不考虑镜像电流的存在，只考虑空间导线电流的效应即可。计算时先按各相导线的电流，算出空间某点磁感应强度的垂直分量和水平分量，然后进行合成，合成时不能单纯按矢量相加原则处理，还应考虑它们之间的时间相角差。拾电线路磁场测t测量翰电线路下三相工频磁场的常用方法有:①交流电压表法。该法是用一个线圈做为磁场探头，连接交流电压表以侧t磁场的磁感应强度.磁场探头实际上是个多匝线圈，侧量时将其工于被测的磁场中，由于交变的磁通穿过线圈而在线圈的两端感应出一电动势。根据该电动势及其他相关参数便可算出相应的磁通量，从而确定磁场的磁感应强度大小.②特斯拉(或高斯)计法.该法是按半导体在磁场中的霍尔效应原理，用霍尔探头及电流表、电压表直接侧量磁场的磁感应强度。侧量时将装有矩形片状半导体的霍尔元件的霍尔探头工于被测的磁场中，使交变的磁通穿过霍尔元件平面。当在垂直磁通的方向对shudlon xlonlu gongplnC{chong输电线路工颇盛场(magnetic field of trans-mission hne)交流物电线路运行时导体中流动的负荷电流在周围广大空间产生的工频磁场。三相翰电线路周围空间任一点的工频磁场与工频电场(见粉电戏路工须电场)相似，亦为一随时间变化的旋转场，
