Power transmission tower
The invention provides a power transmission tower which comprises a tower body, a composite cross arm and a lightning arrester, the composite cross arm and the lightning arrester are arranged on the tower body, the composite cross arm comprises a cross arm body, the cross arm body comprises at least one insulator, and the low-voltage end of the at least one insulator is used for being connected with the tower body; the high-voltage ends of the at least one insulator are connected together to form the composite cross arm for hanging the end part of the power transmission line; the arcing component is connected with the end part of the composite cross arm; the lightning arrester is connected with the tower body and located above the composite cross arm. The electrical gap between the arcing component and the lightning arrester is smaller than the electrical gap between the high-voltage end and the low-voltage end of any insulator. The design structure is simple, the lightning arrester is suitable for composite cross arms of various structures, and under the condition that the same lightning protection performance is met, the length of the composite cross arm can be shortened, so that the structure of the power transmission tower is more compact, and the service life of the lightning arrester can be guaranteed.
本申请提供一种输电塔，该输电塔包括塔身、设置于塔身的复合横担和避雷器，复合横担包括：横担主体，包括至少一个绝缘子，至少一个绝缘子的低压端均用于与塔身连接，至少一个绝缘子的高压端连接在一起而形成复合横担用于挂设输电线的端部；招弧组件，与复合横担的端部连接；避雷器与塔身连接且位于复合横担的上方；其中，招弧组件与避雷器之间的电气间隙小于任意一个绝缘子的高压端与低压端之间的电气间隙。上述设计结构简洁，适用多种结构的复合横担，且在满足相同防雷性能的条件下，可以缩短复合横担的长度，使得输电塔的结构更加紧凑，且也能保证避雷器的使用寿命。
