±1100KV直流线路直线塔避雷器装置
摘要：
本实用新型提供一种±1100KV直流线路直线塔避雷器装置，其包含直线塔塔身，直线塔塔身上固定有导线横担，导线横担连接有导线，避雷器装置至少包括：外挑支架，避雷器，引流线；外挑支架自直线塔导线横担斜向上延伸而出，其与导线处于一个竖直面内，其顶端位于导线的正上方；避雷器的低压端悬挂于外挑支架上，避雷器的高压端连接于导线；引流线的下端均连接于导线，引流线的上端连接避雷器的高压端。本实用新型无间隙避雷器装置可将线路的操作过电压限制在1.5p.u以下，缩减间隙值进而减少铁塔塔头尺寸，大大节省线路工程投资。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a +/-1100KV DC line tangent tower lightning arrester device which comprises a tangent tower body, a wire cross arm is fixed on the tangent tower body, the wire cross arm isconnected with a wire, and the lightning arrester device at least comprises an overhanging support, a lightning arrester and a drainage wire. The overhanging support obliquely extends upwards from thetangent tower wire cross arm, the overhanging support and the wire are located in the same vertical plane, and the top end of the overhanging support is located over the wire. The low-voltage end ofthe lightning arrester is suspended on the overhanging support, and the high-voltage end of the lightning arrester is connected to the wire. The lower ends of the drainage wires are connected to the wire, and the upper ends of the drainage wires are connected to the high-voltage end of the arrester. According to the gapless lightning arrester device, the operation overvoltage of a line can be limited below 1.5 p.u, the gap value is reduced, the size of the tower head of an iron tower is further reduced, and the line engineering investment is greatly saved.
