随着电气化铁路快速发展,铁路运输组织对接触网的要求越来越高,接触网的安全责任业越来越重要。而由于接触网存在架设线路长、地理环境复杂、气候环境多样、供电电流大、负荷变化快、电流冲击大等客观事实,使得接触网不可避免的会发生各种故障,为了及时发现由于电力机车在运行过程中出现电流过大出现烧断接触线的现象,本文提出一种接触网电连接过流监测系统,实现对电气化区段接触网电流监测和故障分析预警。
With the rapid development of electrified railway, the requirements of the railway network on the catenary network are getting higher and higher, and the catenary’s responsibility for the security industry is becoming more and more important. However, due to the fact that the catenary network has such problems as erecting long lines, complex geographical environment, diverse climatic environments, large supply current, rapid load changes and large current shocks, various failures are inevitably occurred in the catenary network. In order to timely find out that the electric locomotive In the course of running, there is a phenomenon that the current is too big and the contact line is blown out. In this paper, a system of overcurrent monitoring of the catenary electrical connection is put forward to realize the monitoring of the catenary current in the electrified section and the early warning of the fault analysis.
