双语例句
- Using this fault phase selector, back-up distance relay for double circuit lines on the same tower can distinguish between cross country faults near to the end line and internal phase-phase faults responsibly by set coordination.
同杆并架的后备距离保护应用此选相元件，通过适当的整定配合，能可靠地区分靠近线路末端跨线故障和区内相间故障，提高距离保护I段的正确动作率。 - The distance protection function is divided into signal measurement module, start module, fault phase selector module, impedance relay module and oscillation blocking module. Distance protection carries out the measuring impedance, which has operating characteristics of Polygon.
将距离保护功能划分为信号测量模块、启动模块、故障选相模块、阻抗继电器模块和振荡闭锁模块等部分，开发了多边形动作特性的测量阻抗式距离元件的虚拟保护实验系统。
