一种楔形防雷引下线接续装置及其使用方法

本发明公开了一种楔形防雷引下线接续装置及其使用方法，包括连接输电杆塔的接头、连接接地网的石墨带以及将接头和石墨带连接的楔形导电套管；楔形导电套管的外壁设有供镀锌圆钢插入的圆管，镀锌圆钢远离楔形导电套管的一端与接头连接，楔形导电套管的小径端供石墨带远离接地网的一端穿入，且石墨带的该端再次从楔形导电套管的小径端穿出，以在楔形导电套管内的石墨带上形成折弯段，石墨带的折弯段内设有楔形卡板，楔形导电套管的外部还套设有将楔形导电套管密封的热缩管，本发明将两种材料的引下线密封结合，杜绝氧气和水分进入，从而阻断石墨材料和金属材料法师电偶腐蚀的通道，接触电阻小，达到防止引下线金属材料这端腐蚀的目的。 The invention discloses a sliding block type wedge-shaped lightning protection downlead connecting device which comprises a connector connected with a power transmission tower, a graphite belt connected with a grounding grid and a wedge-shaped conductive sleeve connecting the connector and the graphite belt. The outer wall of the wedge-shaped conductive sleeve is provided with a circular tube for insertion of the galvanized round steel, one end, far away from the wedge-shaped conductive sleeve, of the galvanized round steel is connected with the connector, and the small-diameter end of the wedge-shaped conductive sleeve is used for penetration of one end, far away from the grounding grid, of the graphite belt and penetr
