摘　　要：本文介绍了雷击微波塔时天馈线电缆分流和机房内磁场强度的模拟试验结果。在此基础上估算了不同雷击电流下，可能由天馈线电缆引入机房的感应电压值，以及机房中间可能出现的磁场强度。A simulating experiment on the effectcau;ed by lightning stroke on microwave communica-tion towers were carried out. Test resuIts on lightningcurrent shunt through microwave cable shields and thetransient space magnetic field in the communication e-quipment room are presented. Based on the;edata,the induced interference voltage on the microwave ca-ble and the space magnetic field at several points insidethe communication equipment room under differentamplitude and probability of lightning current are esti-mated.
