摘要
通过总结配电网故障定位已有的实践方法和理论,提出了能够快速对其故障点进行定位与指示的新系统——新型配电网数字故障指示器。该故障指示器根据配电网的特点,结合故障定位模式及一般故障的判断依据,通过对防雷交流滤波电路、整流直流滤波电路、电源转换模块电路、监测电路部分电路以及主控屏监测系统进行设计,在功能上实现了对配电网上故障的快速定位,使配电网运行更为安全可靠。
Based on the demand of electricity,by summarizing the existed distribution network fault location and theoretical practices,a new system is Proposed,which is able to locate and instruct to its point of failure quickly-the network fault indicator of Utility digital distribution,The fault indicator based on the characteris-tics of the distribution network,combined with fault location model and the general failure of judgment basis, through the designment of the Lightning AC filter circuit、DC rectifier filter circuit、Power conversion module circuit、Monitoring circuit and Master screen monitoring system,achieve a rapid positioning of the online distri-bution of failure,So that the distribution network is running more secure、reliable、high-quality and efficient economy.
