摘要
根据GB／T-24338-2（轨道交通电磁兼容）标准，提出了离线电弧所产生的电磁干扰的测试方案，并选择了在成灌高铁上实施测试。在车下进行EMI标准测试、外场步进EMI测试，并将测试结果分别与GB／T-24338和国家环保标准GB9175-88进行了对比分析，结果表明5倍冗余度下的动车环境磁场强度在特殊工业环境许可范围内。
According to the GB/T-24338-2 standard （railway applications electromagnetic compatibility）, a test scheme for EMI generated by pantograph-catenary electric arc is proposed and the test has been implemented on the Chengdu-guanxian High-speed Railroad. The EMI standard test and the out-field stepping EMI test are implemented off the locomotive, the test results show that the environmental magnetic field intensity around the bullet train caused by the electric arc within the scope of permission for the special industrial environment under 5 times of redundancy in comparison with the GB/T-24338 and GB 9175-88.
