The invention discloses a high-insulation stray current protection method and a high-insulation stray current protection system for a regional track, which are used for realizing stray current protection of a protection region in which a subway line and a buried metal pipeline are crossed or parallel. According to the regional track high-insulation stray current protection method and system, for a key region where a subway line and a buried metal pipeline are crossed or parallel, insulating joints and direct-current circuit breakers are additionally arranged on running rails at the two ends of a protection region, and the running rails on the two sides of the region are connected through bridging cables; according to the technical scheme, leakage of stray current in the protection area can be reduced, stray current generated when current in other areas in the line flows through the protection area can be reduced, and therefore protection cost is reduced, safety, reliability and service life of a walking rail, peripheral equipment and a system in the protection area are greatly improved at the same time, and the service life of the walking rail and the peripheral equipment and system in the protection area is greatly prolonged.
本发明公开了一种区域轨道高绝缘的杂散电流防护方法及系统,用于实现地铁线路与埋地金属管线交叉或平行的防护区域的杂散电流防护。本发明区域轨道高绝缘的杂散电流防护方法及系统针对地铁线路与埋地金属管线交叉或平行的重点区域,通过在防护区域两端的走行轨加设绝缘节和直流断路器,并使用跨接电缆连接区域两侧的走行轨,不仅能够减少防护区域内的杂散电流的泄漏,还能降低线路内其他区域的电流流经防护区域时所产生的杂散电流,从而在降低防护成本的同时,大幅提升防护区域的走行轨及周边设备、系统的安全性、可靠性及使用寿命。
