摘要
BUS1000型母线保护可以自适应双母线系统隔离刀闸位置的变化,保护动作速度快,抗TA饱和能力强,在微机母线出现以前受到了广泛的欢迎,我国也生产了大量类似技术的产品,对电力系统的安全稳定运行起到了非常大的作用,一直到现在还有很多产品运行在电力系统。但该母线保护在刀闸操作过程中存在不能出口的问题,文章对该问题进行了分析并提出了相应的解决方案。
BUS- 1000 Bus -bar protective device made by GE can adopt running m ode of double bus system, and distingusish correctly between internal and external faults ha the event of CT saturation, and provide short tripping time. It is widely used before appearance of digital bus - bar protection. A lot of devices in same technology made in China and are runnhag in power system today, which has great effects on security and stability of power system. But during the switching operation, BUS - 1000 will fail to trip. This paper gave a analysis of this problem and provided a solution, which has special reference for the personnel of using this type bus - bar protection.
