接触悬挂锚段关节电流分布仿真研究

Study on Simulation of Current Distribution for Overlap Section of Contact Suspension

高速铁路接触悬挂锚段关节工作支电连接线出现散股断线问题对整个锚段关节影响较大。为研究接触悬挂锚段关节电流分布规律及工作支电连接线断线造成的电气影响,通过仿真与实测结合的方式对锚段关节关键零部件进行测量并验证,在获取关键零部件参数后对整个锚段关节进行建模分析,对比去工作支电连接后锚段关节载流吊弦电流变化规律。

The occurrence of the problem of breaking of electrical connection wirers of the working contact lines of overlap section of contact suspension has a great impact on the whole overlap section of contact suspension.In order to study the electrical influence caused by the current distribution regularities in overlap section of contact suspension and breaking of electrical connecting wires of working contact lines,the key fittings of the overlap section are measured and verified through a combined mode of simulation and actual measurement.After obtaining the parameters of the key fittings,modelling analysis is made for the entire overlap section for comparison the current variation regularities of current carrying droppers in overlap section with elimination of electrical connecting wires for the working contact lines.
