一种柱上变压器位置测量新方法的探讨

Research on a New Measuring Approach of Pole-Mounted Transformers Location

为提高柱上变压器位置测量结果的准确度,首先通过辅助测量装置在柱上变压器一侧引测两个测点,然后用RTK(real-time kinematic)测量两个引测点的平面位置(即水平面上的二维坐标),最后,将两个引测点的平面位置和两个引测点与要测量的点(柱上变压器位置点在地面上的投影点)之间的水平距离结合,计算出要测量点的平面位置(即水平面上的二维坐标)。该方法测量结果准确度高,成本低,使用操作简便且安全可靠,在保证精度的前提下提高了柱上变压器位置测量的效率。

To enhance the accuracy of location,paper surveys two points through the auxiliary measuring device set on one side of the pole-mounted transformer,then use RTK to obtain the two points’plane location(that is,in the two-dimensional coordinates on the horizontal plane),finally combines the plane position of the two points with the horizontal of the two points that are going to be measured(the projected point on the ground of the pole-mounted transformer’s position)and calculates the plane location(in the two-dimensional coordinates on the horizontal plane).With the high measurement accuracy,low cost,this approach is safe,reliable,and easy for operation,improving the efficiency of the pole-mounted transformer position measurement while ensuring the precision accuracy.
