一种电动汽车充换电站的电能质量预警装置
摘要：
本发明提供了一种电动汽车充换电站的电能质量预警装置，其特征在于，所述装置包括数据处理器(1)、电能质量指标大小指示灯(2)、报警喇叭(3)、数据传输线(4)、电能质量监测仪(5)、电压线(6)、电流线(7)；所述数据处理器(1)内置有电动汽车充换电站模型库；所述数据处理器将电能质量监测仪(5)上传过来的信号进行分析和处理，并将处理结果传送给电能质量指标大小指示灯(2)进行显示，同时通过对比电动汽车充换电站模型库中的计算结果数据，判断是否预警，并将判断结果传递至预警喇叭(3)。本发明的方法实现了直观、及时的显示电动汽车充换电站电能质量指标大小和对充换电站电能质量预警的功能。
摘要（英）：

The invention provides a power quality early-warning device for electric vehicle battery charging and swapping stations. The power quality early-warning device is characterized in that the device comprises a data processor (1), a power quality index indicating lamp (2), an alarming loudspeaker (3), a data transmission line (4), a power quality monitoring instrument (5), a voltage line (6), and a current line (7); an electric vehicle battery charging and swapping station model library is built in the data processor (1); the data processor analyzes and processes a signal uploaded by the power quality monitoring instrument (5), and transmits a processing result to the power quality index indicating lamp (2) for display; and meanwhile, the processing result is compared with calculation result data in the electric vehicle battery charging and swapping station model library, whether or not to carry out early-warning is judged, and a judging result is transmitted to the alarming loudspeaker (3). By adopting the method, the power quality index of an electric vehicle battery charging and swapping station can be visually and timely displayed, and early warning on the power quality of a battery charging and swapping station is achieved.
