Abstract

At present, China's rapid economic development in the support of the railway industry has entered a glorious era, the development of strength is unprecedented. The operation of the train speed, train running environment, train load can have greatly improved, the rapid ascension also brought all the researchers concern, that is how to effectively ensure the pound security vehicles, also become the focus of the whole society. SS4 modified electric locomotive is one of the main models of freight locomotives in our country. It is a kind of locomotive developed on the basis of SS4 electric locomotive. It has the advantages of smooth start, high speed and large cargo delivery. Because of its good performance and high economic benefits, it has been widely used and praised. The split camera is one of the main motors of the SS4 modified electric locomotive auxiliary system, its performance directly affects the normal operation of other auxiliary motors. Many of the faults of the asynchronous motor will occur on the splitter, but the splitter has its own characteristics. From the analysis of fault splitter, main circuit fault and motor fault circuit fault, this paper will be focused on SS4 modified electric locomotive splitter for analysis and processing, and have a comprehensive understanding to quickly and accurately find the fault splitter and timely remove the split camera,

Key words：SS4 modified electric locomotive; splitter circuit fault; fault processing
