摘要
城市轨道交通工程各机电设备系统、弱电系统以及车辆等之间的电磁兼容性设计一直是工程建设中的重要环节,特别是国内尚未有采用25 kV交流牵引制式、地铁列车的城市轨道交通线路成功开通和运营的案例,其电磁干扰方面存在诸多的不确定性。通过对城市轨道交通25 kV交流牵引系统电磁环境的模拟测试,对测试数据进行分析、研究和论证,提出了成都18号线25 kV交流牵引系统电磁环境分析结论,有利于18号线后期的设备选型、电磁兼容性设计及电磁干扰防护,并为类似工程提供借鉴和参考。
Design of electromagnetic compatibility between all the electromechanical equipment, low voltage systems and the vehicles in urban rail transit is an important link in the engineering construction. However domestic urban rail transits have neither experience of using 25 kV AC traction system nor such metro trains on any metio lines in commercial operation for any case study, there exists many uncertainties in the electromagnetic interference. Through simulation test on electromagnetic environment of 25 kV AC traction system in rail transit, this paper makes an analysis, research and demonstration on the test data, and puts forward the conclusion of electromagnetic environment of 25 kV AC traction system on Chengdu metio line 18, which is beneficial to the selection of equipment, design of electromagnetic compatibility and protection solution for electromagnetic interference. Meanwhile it provides reference for the future similar projects.
