摘要
负荷开关和断路器的配合使用已广泛应用于配电网中,而精确检测和处理非接地系统中的接地故障是配电系统的一个重要课题。介绍了高性能的SOG(storage over current ground)智能型线路保护开关的原理、特点和功能,进一步阐述其与上级变电所断路器的配合应用,实践证明SOG在配网中发挥重要作用,具有良好的应用前景。
Load switches and circuit breakers have been widely used in the distribution network. And accurate detection and treatment of earth-fault of non-grounding system has been an important topic in power distribution system. The principles, characteristics and functions of the high-performance SOG (storage over current ground) smart line protection switches were introduced, and then its performance with the circuit breakers in higher-level substation was elaborated. Practice has proved that the SOG plays an important role in the distribution network, at the same time has good application prospects.
