一种±500kV直流输电线路避雷器安装支柱式结构
摘要：
一种±500kV直流输电线路避雷器安装支柱式结构，包括基础、塔腿、变截面塔身、等截面塔身、支柱顶端与避雷器本体连接板，塔腿固定在基础上，变截面塔身设置在塔腿上，变截面塔身上设置等截面塔身，等截面塔身的顶端设置支柱顶端与避雷器本体连接板。本实用新型通过将塔腿设置在基础上，塔腿上设置变截面塔身，变截面塔身上设置等截面塔身，等截面塔身上设置支柱顶端与避雷器本体连接板，该结构独立于在运线路铁塔，对在运线路无影响，不需要对现有铁塔进行改造，并且结构简单，易于操作。本实用新型对在运线路难以进行相应改造的耐张塔或直线塔是可行、有效、易操作的避雷器安装方式。
摘要（英）：

The utility model relates to a strut type structure for mounting of a lightning arrester on a +/-500V direct current power transmission line. The strut type structure comprises foundations, a tower leg, a variable-cross section tower body, an equal-cross section tower body, and a strut top end and lightning arrester body connecting plate, wherein the tower leg is fixedly arranged on the foundations, the variable-cross section tower body is arranged on the tower leg, the equal-cross section tower body is arranged on the variable-cross section tower body, and the strut top end and lightning arrester body connecting plate is arranged at the top end of the equal-cross section tower body. The strut type structure has the advantages that the tower leg is arranged on the foundations, the variable-cross section tower body is arranged on the tower leg, the equal-cross section tower body is arranged on the variable-cross section tower body, and the strut top end and lightning arrester body connecting plate is arranged on the equal-cross section tower body; the structure is independent from an iron tower of a running line, so the influence on the running line is avoided, and the modifying of the existing iron tower is not needed; the structure is simple, and the operation is easy; the method is a feasible, effective and easy method for mounting the lightning arrester on a strain tower or a line tower with difficulty in modifying the running line.
