摘　　要：断路器继电保护装置中一些端口间的互连需要用到扁平电缆,扁平电缆是数根导线并列在一起传输的一组数据线,其中有模拟信号线、数字信号线和地线。由于传输的信号各不相同,信号频率较高,导线距离较长,因此其产生的串扰不容忽视。研究在电缆结构参数确定的情况下,如何布置各数据线的排列顺序,以使关键信号线不至于受到不可接受的干扰,数字信号线不发生高低电平误判断。The interconnection between some ports in the circuit breaker relay protection device requires the use of flat cables.A flat cable is a set of data lines that are transmitted side by side with several wires,including analog signal lines,digital signal lines,and ground wires.Since the transmitted signals are different,the signal frequency is high,and the wire distance is long,the crosstalk caused by it cannot be ignored.This paper mainly studies how to arrange the arrangement order of each data line when the cable structure parameters are determined,so that the key signal lines are not subject to unacceptable interference,and the digital signal lines do not misjudge the high and low levels.
