摘　　要：探究了面向高压电网的过电压数据采集系统的设计要点。该系统由电压传感器、触发电路、数据采集卡等组成,电压传感器实时获取高压电网的电压参数,利用触发电路判断是否存在过电压事件。如果存在则满足触发条件,将采集到的数据存入数据采集卡中。此外还设计了保护单元和抗干扰装置,前者能保证电压数据采集的连续性,后者能提高抗干扰能力进而提高了电压数据质量,满足了后续的数据分析需要。This paper explores the design points of an overvoltage data acquisition system for high-voltage power grids.The system consists of voltage sensors,trigger circuits,data acquisition cards,etc.The voltage sensor obtains real-time voltage parameters of the high-voltage power grid and uses the trigger circuit to determine whether there is an overvoltage event.If it exists,the triggering condition is met and the collected data is stored in the data acquisition card.In addition,protection units and anti-interference devices have been designed.The former can ensure the continuity of voltage data acquisition,while the latter can improve anti-interference ability and thus enhance the quality of voltage data,meeting the needs of subsequent data analysis.
