摘要
为了解三峡电站 5 0 0kV八回出线架空跨越永久船闸实际产生的电磁环境 ,实测并分析了永久船闸区域的电磁环境参数 ,结果表明现行最高水位下闸室中 ,线下船舶上的最大工频电场强度、船闸周边的最大工频电场强度和磁感应强度分别为 2 .0 1、1.82kV/m和 1.17μT ,均小于我国环保标准中规定的限值 ;无线电干扰水平也非常低。不影响闸室船上通信及中、短波广播、电视接收。
In order to know the EM environment at the condition of crossing the ship-gate with eight 500kV overhead transmission lines, The EM environment parameters at ship-gate area are analysis and measured. The results show that The max. power frequency electric field and magnetic induction intensity on ship and around the gate are respectively 2.01、1.82kV/m and 1.17μT. They are lower than the limit value of standard. The radio interference is also low. The communication, radio broadcast and TV are not affected.
