摘要
采取建立架空送电线路导线空间曲线方程的方式,运用微积分等数学理论对点与导线、直线与导线、导线与导线之间的最小电气距离的公式求解方法进行了系统推导,所得计算方法与以往工程设计中通常采用的作图法、解析法及穷举法相比,具有计算简单、结果精确、适用范围广等优点。
Based on the conductor oblique parabola equation of overhead transmission line, the formula method for solving the minimum electric clearances of spot-to-conductor, beeline-to-conductor and conductor-to- conductor is discussed systemically with mathematical theories. This method is easy to be applied in engineering calculation for the logical derivation and clear conclusion. Comparing with the traditional methods to solve conductor electric clearance adopted in overhead transmission line design such as graphical method, analysis method and exhaustive method, the formula method suggested in this paper has more concise procession, more precise resuh and wider applicability.
