Method for drilling 500kV high-voltage line through 220kV double-circuit transmission line
The invention discloses a method for drilling a 500kV high-voltage line on a 220kV double-circuit transmission line, and solves the problem of how to drill a 500kV and above high-voltage line at low cost. An upper, middle and lower three-cross-arm structural form vertically arranged on a traditional double-loop iron tower is changed into an upper and lower two-cross-arm structural form, a traditional horizontal upper cross arm structural form is changed into an arch-shaped upper cross arm structural form, an insulator string is arranged between the arch-shaped upper cross arm and a tower body, an upper wire and a middle wire are arranged, and the upper cross arm and the lower cross arm are connected through a wire. The distance of each wire hanging point on one side of the tangent tower in the vertical direction is reduced, that is, the space distance occupied by the upper wire hanging point, the middle wire hanging point and the lower wire hanging point in the vertical direction is reduced, a certain horizontal distance exists among the three wire hanging points, and it is guaranteed that the electrical clearance circles of the wires do not coincide; and the same-tower double-circuit line can drill over other high-voltage lines.
本发明公开了一种220kV双回输电线路钻越500kV高电压线路方法，解决了如何低成本钻越500kV及以上高电压等级线路的问题。本发明将传统的双回路铁塔上垂直布置的上、中、下三横担结构形式，更改为上、下两横担结构形式，将传统的水平的上横担结构形式更改为弓形形状的上横担结构形式，在弓形形状的上横担与塔身之间布置绝缘子串，并设置上导线和中导线，减小了直线塔一侧上各导线挂点在垂直方向上的距离，即上导线挂点、中导线挂点和下导线挂点之间所占据的在上下竖直方向上的空间距离，并且三个导线挂点间有一定水平距离，保证各导线电气间隙圆不重合；实现了同塔双回线路钻越其他高压线路。
