Description

TECHNICAL FIELD

[0002] The contact rail system is an important component of traction power supply, which is composed of steel-aluminum composite rail, insulating support, protective cover and other components, and its mechanical properties and operation safety are directly related. Among them, the insulating support and the protective cover are made of glass fiber (non-metal) material, which is subjected to long-term stress or high pressure, and there is aging and performance degradation during the life cycle. After failure, it will directly affect power supply and operation.

[0003] The contact rail insulating support and the protective cover generally adopt annual inspection and monthly patrol maintenance form, but there are serious hidden dangers such as boot and track collapse due to batch penetrating cracks of insulating protective equipment. Because there is no special detection platform for subway operation, the operation personnel independently detect by simple and rough methods such as hammering and car hard pulling, which has poor accuracy and high risk, resulting in long problem rectification period and difficulty in radical treatment. Whether to replace the contact rail insulating support and the protective cover after damage depends on subjective judgment, which seriously wastes operation cost. Because the fault degree cannot be accurately judged, the "replace as much as possible" method is adopted. According to statistics, the annual replacement of spare parts costs about 101,000 yuan.

[0004] At the same time, maintenance personnel cannot accurately master the material performance, and the maintenance measures lack pertinence. At present, unified maintenance measures are adopted, mainly for checking cracks, discoloration, etc. There is no differential maintenance according to specific performance.
