更新时间:2023-05-28

【摘要】From technology importation to independent innovation, Chinese High speed railway(HSR)has been rapidly developed in the past a few years.However, this technology development mode introduces very complex electromagnetic environment of HSR system,which is based on various equipment with different Electromagnetic compatibility(EMC) design. Consequently,the suppression of electromagnetic disturbance and the electromagnetic protection is becoming an urgent issue for HSR. The characteristics of traction power supply technology, train operation control technology and other core technologies are quite unique in Chinese HSR. In this paper, the EMC and the electromagnetic safety issue of Chinese HSR is discussed, which is derived from technology development mode and core technology characteristics. The limitation of the high speed train’s exportation due to the lack of test method for the train’s emission is also analyzed. Combining the electromagnetic environment characteristic and the development planning of Chinese HSR, several suggestions in the research of antielectromagnetic interference, electromagnetic protection in the strong electromagnetic field and the whole large system’s radiation emission test method are put forward.
