The Analysis of checking Gap Circle ahout the 1okV Linear Dual Concrete Power Pole

摘要:

:以山区 10 kV 直线水泥双杆为背景，对直线水泥双杆铁部件进行电气设计及校验。利用 MathCAD 软件编写 计算程序，考虑不同气象区、不同海拔地区、不同截面导线、不同类型的悬垂绝缘子串等多种条件，通过验算调整 Kv 值，计算 10 kV 直线水泥双杆的绝缘子串摇摆角，绘制间隙圆图，确定 10 kV 直线水泥双杆横担尺寸和斜撑的电气位 置，为横担和斜撑的结构设计提供必要的电气条件。

Abstract:

:Taking 10 kV straight dual concrete pole in mountainous area as the background，the electrical design and verification for ironwork of straight dual concrete pole are carried out． MathCAD software is used to write the calculation programs． Considering different meteorological district，different altitude area，different cross － section conductor，different suspension insulator string and other conditions，the Kv value is adjusted，the swing angle of insulator string of straight dual concrete pole is calculated，the diagram of gap circle is drawn，and the size of cross arm and the electrical location of diagonal bracing are determined for 10 kV straight dual concrete pole，which provides the necessary electrical conditions for the structure design of cross arm and diagonal bracing．

Key words:straight dual concrete pole; safe distance; Kv value; swing angle; gap circle
