摘　　要：对高速铁路接触网短路试验的意义和内容进行了说明,重点对接触网短路试验的类型和接地故障点的选择进行了介绍。对试验时间的选择、试验程序、试验前的准备工作、试验中的安全措施和注意事项进行了总结提炼,提出选择车载断路器接地并设置自动分闸回路的必要性,以降低短路试验的风险。对与钢轨的接地连接提出具体措施,防止钢轨烧伤事故,强调组织好试验的重要性和将成果应用于实践的意义。This paper mainly explains the content and importance of short circuit test on the high-speed railway’s overhead line system.Special attention is paid to the types of the test and the choice of ground fault points.To reduce the possible risk from this short circuit test,this paper focuses on the time,preparations,safeguard measures and rules of this test and at the same time points out the necessity of applying on-board circuit breakers while setting automatic bifurcation circuit.To avoid rail burns,this paper gives some concrete countermeasures to deal with the ground connection with rails.The importance of properly organizing this test and putting the knowhows into practice is also emphasized in this paper.
