提高牵引变电所故障测距装置精确度的对策

指出牵引变电所故障测距装置的精确度是动态变化的,应根据接触网、变电所设备及装置运行情况的变化及时调整故障测距整定值,以提高其精确度,提出电气化铁道复线并联供电时避免线路互感影响牵引变电所故障测距装置精确度的简便方法即复线单线化。

Counter-measures on Improvement of Precision of Traction Substation Fault Location

Points out the precision of traction substation fault location device is dynamic and changing, which shall be improved by means of adjustment of the setting values in accordance with the operational status of the equipment and devices of the OCS and substations so as to improve the precision; proposes a simple method that is to convert the double track to single track to prevent the parallel power supply to the double track of electrified railways from interfering the precision of traction substation fault location due to the mutual inductance of the lines.
