摘　　要：发电厂内存在大量的工频磁场辐射源,可能超过相关标准。通过创新性地自制磁感应强度测试仪,对电厂内发电机封闭母线接口处工频磁感应强度进行了测试,得出了该处磁感应强度超过国家标准限值的结论,并提出了相关的防范措施,可为其他电厂开展磁场强度检测提供参考。There are a large number of power frequency electromagnetic field radiation sources in a power plant,which may exceed the relevant standards.By a magnetic induction intensity tester developed innovatively,tests are performed on the power frequency magnetic induction intensity at the closed bus interface of the generators in a power plant.It comes to a conclusion that the magnetic induction intensity at the interface exceeds the national standard limit,and the relevant preventive measures are put forward,which is available to reference for other power plants to carry out magnetic field strength tests.
