1. 前言高压配电线路的水平线间距离,在设备标准中规定:当用两个悬垂绝缘子串时为750毫米。但是,在气象条件和地理条件不好的地方,有发生混线事故的例子。如羽越干线,它是地处山区并沿海岸架设高压信号架空线路的地方,不但风向变化多端,而且风速的变化也很复杂,考虑飓风的风速,在强风区段的水平线间距离定为900毫米。 2.线间距离计算式有种种实验公式,一般使用的计算公式如下。
1. INTRODUCTION The horizontal distance between HV distribution lines is defined in the equipment standard as 750 mm when using two overhanging insulator strings. However, where weather conditions and geographical conditions are not good, there are examples of mixed-line accidents. If the feather line, it is located in the mountains and along the coast erecting high-voltage signal overhead lines, not only the wind direction varied, and the wind speed is also very complicated changes, taking into account the hurricane wind speed in the strong wind section of the horizontal distance between the set at 900 mm . 2. Line distance calculation formula There are a variety of experimental formula, the general use of the formula is as follows.
