摘要
在越级跳闸的情况当中,十分常见的一种就是10kV的越级跳闸现象。10kV的线路发生故障之时,如果无法及时的跳开相应的开关进而切除故障,那么就会引起主变变低现象,从而发生跳闸。由于电网当中的10kV线路使用的供电方式是放射性的,所以一旦出现越级跳闸的现象,对于整个供电系统的可靠性的影响很大。以下通过对其越级跳闸的原因、对策等进行了分析。
10kV override tripping phenomenon is one of the very common cases of override tripping. When the 10kV line failure happens, if it can not promptly jump the corresponding switch and remove the fault, it will cause the main change low phenomenon, and thus causing tripping. Because the power supply way adopted in 10kV line in the power grid is radioactive, override tripping can greatly affect the reliability of power supply system. This article analyzes the causes for the tripping and countermeasures.
