Of stray current protection should be used mainly to avoid in order to row as a supplement, bined with antihandling, to strengthen the monitoring of principle. Combined with years of experience in site construction, From the stray current protection methods, techniques and principles of the stray current monitoring of urban rail transit stray current protection were discussed.Keywords: rail traffic, stray current, counter drainage, single connecting device 1 the principle of stray current protection Rail transit DC traction power supply system, as long as the taking by going back to rail conductor, the resulting stray current is inevitable. In order to reduce the stray current hazards, they should seek to reduce stray electrical current. This need to take effective measures to prevent stray current to control the stray Current extent permitted. Stray current is basically the use of protective works mainly in order to prevent in order to row as a supplement, bined with antihandling, to strengthen the monitoring of principle. (1) to prevent the main Control all possible ways of stray current leakage to reduce the stray current into the rail transportation system, the main structure, equipment and related facilities along the vicinity of the structure of steel. Specific implementation, as it relates to multiprofessional and professional, need to work closely with the various types of jobs, particularly in the construction design stage to consider a more prehensive control measures to minimize the DC system with other building electrical connection. Measures that can be taken are: range of traction substation and the DC power supply equipment and structure in the installation and structure of the main steel insulation installation。 running track during construction, the use of ballast and track installation insulation。 by the introduction of rail transport within the outside world or by rail transport within the metal pipes shall be led to the introduction of insulation before and after extraction。 the establishment of rail transit in the structure of steel electrical connectivity to all structural steel and access points connected together, will be the leakage of stray current drainage HVDC system. (2) as a supplement to row Set up the stray current collection system. This collection system for stray current leakage from the back to track after the first encounter of the return of the small channel resistance may be best to limit the stray current in the system to prevent stray current leakage to the outside of the system. 2 different sections of the stray current drainage system The specific implementation, the different sections should be taken to the appropriate drainage measures. elevated section of stray current drainage system Shanghai Mass Transit Line Elevated general simply supported the use of castinplace concrete box girder structure, the piers between the box and rubber bearing is installed through the plate, play the effect of insulation installed. In the stray current protection system, castinplace concrete simply supported box girder of the surface of the internal network and the main structure of reinforced steel welding net, as the collection and drainage channels, stray current protection is the first line of defense. Leads to the structure with the surface of copper as copper terminal drainage, using 1 150mm2 cable to each castinplace concrete box girder simply supported copper drainage connecting terminal, and then installed in the substation through the drainage within the cabinet, the scattered row range of stray current into the DC power supply system, play a protective role of stray current. At the same time, copper terminals can also be used as stray current monitoring system for monitoring points. Stray Current interval shield tunnel drainage system Range of shield tunnel segment by a circular one linked through bolt, each shield segment with structural steel. Installed in a tunnel segment is prefabricated. By stray current professional requirements of each segment within the structure of steel into a mesh, welded together, so that the internal structure of steel segment electrical connectivity through the steel washer will lead to a good electrical connection point. Tunnel Segment operation assembled by bolts and nuts will be the structure of the tunnel segment reinforced all the electrical connections to form equipotential body. Central to the adoption of the two vertical bolts to each segment, each segment connecting ring, forming a Faraday cage, on the subway for electric shielding to prevent external leakage of stray current MTR to reduce the pollution of the environment on the ground floor. overall track bed of the stray current protection Roadbed for a whole range of underground tunnels, due to the overall Road, take the rail bed in the following, and the nearest track, the track most likely to direct the collection of stray current leakage. Therefore, the shield tunnel, the use of the internal structure of the whole track bed reinforced electrical connection, the establishment of the main collection of s
