Rail transit electromagnetic compatibility Part 3-1. Locomotive trains and complete vehicles1 ScopeThis part of GB/T 24338 specifies all types of rolling stock (including towed vehicles, trailers and city vehicles used in urban streets). Vehicle) emission and immunity requirements. This section applies to the frequency range from 0GHz to 400GHz. Bands without limit requirements do not need to be tested. The range of equipment in this section is limited to rolling stock and each energy interface (input and output). for locomotives, trains, trams Wait until the limit is reached to the current receiver (pantograph, power shoe), for the trailer, to the AC or DC auxiliary power connector. Due to the current receptor It is part of the towing vehicle and it is therefore impossible to completely eliminate the influence of the power line interface. Slow testing minimizes these effects. This section specifies the emission limits for rolling stock to the outside world. Additional compatibility requirements for rail systems are identified in the EMC program, such as those specified in GB/T 28807. All equipment installed on rolling stock should meet the basic requirements of GB/T 24338.4. In exceptional cases, the device meets other EMC standard, but there is no data to prove that the requirements of GB/T 24338.4 are met, and the equipment needs to be installed in the vehicle system. When testing EMC and/or EMC analysis and testing to determine the difference between the equipment and GB/T 24338.4 requirements. See GB/T 24338.2 for the treatment of electromagnetic interference of the track system as a whole. The specific provisions of this section should be used in conjunction with the general provisions of GB/T 24338.1.2 Normative referencesThe following documents are indispensable for the application of this document.

Therefore, the test should be in the code that produces the maximum emission. In the working mode. The typical working mode only requires all the equipment that should be continuously running when the system works normally; when working normally, the short-time working equipment (such as the door) Although it is possible to increase the launch, it is not required to operate. Does not involve the degraded working mode of the device. The test program shall specify the system configuration and mode of operation of the test. The test report shall detail the actual working conditions during the test.5 Immunity test and limitThis part does not specify the vehicle immunity test, if all equipment meets the requirements of GB/T 24338.4 through the EMC program The immunity limit requirements of the integrated vehicle are integrated into the equipment to meet the requirements.6 Launch test and limits6.1 General The emission test and limits of the rolling stock in this section shall be as far as possible to ensure that the typical equipment in the adjacent rail system is not affected by the rolling stock. Disturb. Measurements should be made under well-defined and reproducible conditions. It is impossible to completely isolate the mutual system of the track system and the vehicle during the test. influences. The test conditions for radiated emissions are specified in 6.3.1 and 6.3.2. If different lines of signal equipment, train wireless communication equipment and other equipment (such as axle counting, track circuits and train control systems, etc.) Different types, the operating frequency and waveform of the transmitted signal are also different. Therefore, it should be determined according to the type of signal equipment and train wireless communication equipment. For emission requirements, see GB/T 28807. For equipment other than radio or railway track systems with operating frequencies below 0.15 MHz (if any), electromagnetic The management plan should be considered and the electromagnetic emission margin should be kept in the relevant frequency bands to maintain compatibility with these devices, and the relevant emission value requirements. See Appendix A, but there is no guarantee that these devices will not be disturbed by the track system. 6.2 Interference on external communication lines 6.2.1 Digital communication lines High-frequency digital systems use a variety of carrier or error correction protocols to cope with interference, and the intensity of interference of locomotives in the relevant high-frequency range is not This affects the normal operation of the digital system, so this section does not involve interference with digital systems (such as PCM, ISDN, xDSL). 6.2.2 Analog communication line Analog communication cable interference can be found in Appendix A. There are no limit requirements specified in this section. 6.3 RF electromagnetic disturbance 6.3.1 Test site There are more factors affecting the measurement at the test site than laboratory conditions, including but not limited to. --- Trees, fences, bridges, tunnels or other conductive objects near the track; ---Other vehicles operating in the same interval or near the measuring point; --- Substation near the measuring point, transformer, power cable, underground cable, segmented insulator and overhead contact network/third rail interruption Point and so on. Field factors affecting the measurement should be avoided as much as possible. At least there should be no field factors affecting the measurement between the antenna and the product under test. The overhead contact net/third rail should be as continuous as possible on both sides of the measuring point (not less than.200m). Overhead contact net strut is inevitable and the measuring point should be at the midpoint between the overhead contact net strut and opposite the track (for dual rail, On the side of the track being used). If the rail system is powered by the third rail, the antenna should be placed on the same side of the track (the worst case). The impact of the overhead catenary system and the test site on the test should be considered. In order to eliminate the contact network resonance caused by radio frequency, the test can be changed. on site. The measurement of vehicle noise can take into account the effects of substations, but it is not possible to measure the effects of DC substation load currents at no load. Environmental noise before and after the test should be recorded and environmental noise measurements should not be affected by the vehicle. If the ambient noise is higher than the limit by 6 dB within the specified frequency or the specified frequency range, the measurement may not be performed at these frequencies. However, the test report should record these frequencies. Note. The vehicle is completely powered down and parked in front of the antenna to facilitate environmental noise measurements. 6.3.2 Test conditions The test shall cover the operating mode of all in-vehicle equipment that may generate electromagnetic emissions. The trailer should be tested under static live working conditions (normal operation of the auxiliary converter and battery charger). Antenna should be aligned A device that produces the largest possible emission at a frequency. Only one test is performed for the same passenger car or truck. The towing vehicle should be tested under static and low speed driving conditions. The auxiliary converter should work during the static test (maximum load The maximum emission level is not necessarily generated under conditions. The traction converter should be energized but not working. The antenna should be aligned with the vehicle centerline, otherwise choose pre- The position that produces a larger emission level. In the slow test, the speed should be appropriate, avoiding contact arcing or jumping, and electric braking. The speed of urban vehicles should be (20±5)km/h, the speed of the main line vehicle should be (50±10)km/h. When passing the antenna, the rolling stock should be large within a given speed range About 1/3 of its maximum traction accelerates or decelerates. If the following conditions are met, the static test of the mechanical brake can be used instead of the locomotive that works at 1/3 of its maximum traction force. Line test. ---The traction device can work at rest; --- If the circuit is not used in the brake, the electric brake will not be tested. If the static test with traction replaces the slow test, the limit of the slow test shall be used and the replacement shall be indicated in the test report. reason. For vehicles that are powered by on-board energy storage equipment, the charging process should use slow test and limit requirements. Note. The slow test and limit requirements are used for the charging process (vehicle energy storage equipment) due to the transmission of higher energy in a short time. 6.3.3 Emission limit The emission limit is given in two modes. static test and slow test. The static test emission limit is shown in Figure 1. For the slow test emission limit, see figure 2. Description.
