我在实际工作中,在没有仪器的情况下,使用了米尺(卷尺)测量配电线路转角角度,误差较小,现介绍给读者供参考.本测量方法简单实用,请读者一试。以图1为例说明此办法:图中BAC是已测量的线路方向,A点是角杆位置、AC的反向延长线AC′与AB的夹角∠BAC′即是待测角度α。测量时可将花杆或其他直棒(1米以上)放在AC′线地面上,一端靠 In the actual work, in the absence of instruments, the use of meter (tape measure) measuring distribution line angle, the error is small, are introduced to the reader for reference. The measurement method is simple and practical, please readers. Take Fig. 1 as an example to illustrate this method. In the figure, BAC is the direction of the measured line, point A is the position of the angle bar, and the angle between the AC extension line AC ’and AB is ∠ BAC’. Measurement can be spent rod or other straight stick (1 m above) on the AC ’line ground, one end by
