Description
technical field [0001] The invention relates to the field of electromagnetic compatibility testing, in particular to an electromagnetic compatibility testing system for rail vehicles and rail circuits. Background technique [0002] China's railway transportation is in a period of rapid development, mainly in two aspects: one is the electrification of traction, and the other is the microelectronics and computerization of equipment. The application of microelectronics technology and computer technology to railway signal control and monitoring system has become the development trend of modern railway transportation. [0003] With the continuous development of high-speed and heavy-duty railways, the traction power and current are getting larger and larger, and the electromagnetic compatibility problems between strong electric interference and weak current equipment have become more prominent. For signal equipment such as track circuits that use rails as information transmission...
