摘　　要：暂态录波型故障指示器应用在输配电高压10 kV线路中,由汇集单元和A相采集单元、B相采集单元、C相采集单元组成,三相采集单元分别采集线路ABC三相的电压和电流数据,采集数据通过433 MHz无线通信方式传输给汇集单元,汇集单元将三相数据存储和研判,将结果传输给主站,实现监测10 kV线路和故障精确定位。设备如何应对433 MHz无线通信距离变化、温度变化、通信干扰等影响通信质量的问题,一直难以解决,文章提出调整接收增益挡位、分时隙、调整发射功率等方法解决此问题。Transient wave-recording fault indicator is used in transmission and distribution high-voltage 10 kV lines,which consists of collecting unit,A-phase collecting unit,B-phase collecting unit and C-phase collecting unit.The three-phase collecting unit collects the voltage and current data of ABC line respectively,and the collected data is transmitted to the collecting unit through 433 MHz wireless communication.The collecting unit stores and judges the three-phase data,and transmits the results to the master station,thus realizing the monitoring of 10 kV lines and accurate fault location.How to deal with the problems of 433 MHz wireless communication distance change,temperature change,communication interference,etc,which affect the communication quality,has been difficult to solve.Here,some methods are put forward to solve this problem,such as adjusting the receiving gain gear,time slot and transmitting power.
