一种±500kV耐张塔直流线路避雷器塔身支撑式结构及其安装方法
摘要：
本发明提供了一种±500kV耐张塔直流线路避雷器塔身支撑式结构及其安装方法，塔身支撑式结构包括避雷器塔身支架(1)和避雷器本体托架连接板(2)；避雷器塔身支架(1)的一端安装于耐张塔塔身，避雷器塔身支架(1)的另一端装有避雷器本体托架连接板(2)，避雷器本体(3)安装于避雷器本体托架连接板(2)上；避雷器顶部装设弧形电极(4)，耐张塔绝缘子串(6)下方跳线底部安装有高压端电极，高压端电极(5)位于弧形电极(4)的正上方，高压端电极(5)与弧形电极(4)构成避雷器的串联间隙。本发明利用耐张塔塔身作为线路避雷器支撑，不受地形影响，结构简单，适用性较强。
摘要（英）：

The invention provides a tower body support structure for a +/-500kV strain tower DC line arrester and an installation method of the +/-500kV strain tower DC line arrester. The tower body support structure comprises an arrester tower body bracket (1) and an arrester body bracket connection plate (2), wherein one end of the arrester tower body bracket (1) is arranged on a strain tower body; the arrester body bracket connection plate (2) is arranged at the other end of the arrester tower body bracket (1); an arrester body (3) is arranged on the arrester body bracket connection plate (2); an arc-shaped electrode (4) is arranged at the top part of the arrester; a high-voltage terminal electrode (5) is arranged at the bottom part of a jumper wire at the lower part of a strain tower insulator string (6) and is located right above the arc-shaped electrode(4); and the high-voltage terminal electrode (5) and the arc-shaped electrode (4) form a series gap of the arrester. With the strain tower body as line arrester support, the tower body support structure is not affected by the terrain, and is simple in structure and relatively high in applicability.
