朔黄铁路10kV电力线路故障自动分段装置技术改进研究

Research on the Technology Improvement of 10kv Power Line Fault Automatic Blocking Device of Shuohuang Railway

针对朔黄铁路10k V电力线路故障自动分段装置存在的问题,改进装置逻辑控制方式,增设监控中心。通过数据交互网络,将独立的故障自动分断装置组成故障自动分断系统,实现线路故障集中逻辑判断,将分断装置高压开关与数字化逻辑自动控制柜对接,实现系统解锁与后台数据交互功能。经试运行表明,技术改进后的装置具有稳定性、可移植性、灵活性的特点,提高了装置的利用率。

Aiming at the problem of automatic blocking device of lOkV power line fault in the Shuohuang Railway, we improve logical control mode and add the monitoring center . Through the data exchange network,independent of the fault automatic blocking device form a fault automatic blocking system, which realizes a centralized line fault Logical judgment . The high-voltage switchgear and digital logic automatic control cabinet achieve docking, to achieve the system unlock and background data exchange. The system trial operation shows that the device has the characteristics of stability, portability and flexibility, and improves the utilization of the device.
