Abstract

一种35kV输电线路避雷装置,由避雷针、抱箍、螺栓组成,避雷针(1)的下端与抱箍(2)焊接;避雷针(1)由圆钢制成,上端磨成尖形;抱箍(2)由扁铁弯成并钻有螺栓孔,每个抱箍上焊有两个避雷针组成一个部件,两个部件用螺栓(3)连接成一个避雷装置;将本装置固定在35kV输电线路的杆塔顶上,并与接地线连接,避雷针向斜上方四个方向弯曲成放射状布局,本装置可极大限度地减少了雷电直击导线,避免造成断线、接地、掉闸,设备损坏等事故。

Description

35kV输电线路避雷装置
技术领域
本实用新型涉及一种电力线路避雷装置,具体涉及一种35kV输电线路避雷装置。
背景技术
35kV输电线路在变电站安装有避雷装置,但由于35kV输电线路都比较长,雷击造成断线、接地、掉闸,设备损坏事故时常发生,因此,需要有进一步的解决办法。
实用新型内容
本实用新型的目的就是克服现有技术的不足而设计一种35kV输电线路避雷装置。
为实现上述目的,本实用新型采用的技术方案是:35kV输电线路避雷装置,由避雷针、抱箍、螺栓组成,其特征在于:避雷针(1)的下端与抱箍(2)焊接;避雷针(1)由圆钢制成,上端磨成尖形;抱箍(2)由扁铁弯成并钻有螺栓孔,每个抱箍上焊有两个避雷针组成一个部件,两个部件用螺栓(3)连接成一个避雷装置。
本实用新型相比现有技术的有益效果是:
极大地减少了雷击造成断线、接地、掉闸,设备损坏事故时常发生,生产工艺简单,成本低,安装方便。
附图说明
附图1是本实用新型实施例的结构示意图。
附图2是附图1的俯视图。
图符说明:1~避雷针;2抱箍;3~螺栓。
具体实施方式
附图1是本实用新型实施例的结构示意图,附图2是附图1的俯视图,本实施例35kV输电线路避雷装置,由避雷针、抱箍、螺栓组成,避雷针(1)的下端与抱箍(2)焊接;避雷针(1)由圆钢制成,上端磨成尖形;抱箍(2)由扁铁弯成并钻有螺栓孔,每个抱箍上焊有两个避雷针组成一个部件,两个部件用螺栓(3)连接成一个避雷装置。安装时将本装置的避雷针尖朝上,把抱箍(2)固定在35kV输电线路的杆塔顶上,并与接地线连接,然后将避雷针向斜上方四个方向弯曲成放射状布局(避雷针在安装前可以不弯曲,以便运输)。本装置可极大限度地减少雷电直击导线,避免造成断线、接地、掉闸,设备损坏等事故。
按上述所说的避雷针也可以用角铁、方管、不锈钢等材质制做,所有铁质部件应镀锌。
