架空导线重要跨越区域双联双保护的装置
摘要：
本实用新型公开了一种架空导线重要跨越区域双联双保护的装置，它包括压接线夹，所述压接线夹的一端与架空导线连接，其另一端通过U型环与弧形调整板的一端连接，所述弧形调整板的另一端通过U型环与连接杆的一端连接，所述架空导线上设置耐张保护线夹夹头，所述耐张保护线夹夹头通过两个耐张保护线夹结构架分别与两个耐张保护线夹连杆的一端连接，两个所述耐张保护线夹连杆的另一端与三角板的底角处铰接，所述三角板的顶角处通过直角挂板与所述弧形调整板连接，形成连接杆的双联双保护。本实用新型在主承力线夹损坏之后，后备耐张保护线夹夹头立即动作，由轻微受力转为承担架空线所有拉力，各种可行性后备耐张保护线夹夹头的额定拉断力均可满足各种型号的架空线所产生的瞬时冲击力。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses a device of two protections of regional pair of important leap of air wire, it includes the crimping fastener, the one end and the air wire of crimping fastener are connected, and its other end passes through U type ring to be connected with the one end of arc adjusting plate, the other end of arc adjusting plate passes through U type ring and is connected with the one end of connecting rod, set up strain insulator protection fastener chuck on the air wire, two are connected with the one end of two strain insulator protection fastener connecting rods respectively through two strain insulator protection clamp structure framves to strain insulator protection fastener chuck the other end of strain insulator protection fastener connecting rod is articulated with the base angle department of set -square, the apex angle of set -square department through right angle hanging plate with the arc adjusting plate is connected, forms the two protections of pair of connecting rod. The utility model discloses after the primary load bearing fastener damaged, reserve strain insulator protection fastener chuck moved immediately, was transferred to by slight atress and bore all pulling force of overhead wire, and the specified tensile strength of various feasibility reserve strain insulators protection fastener chuck all can satisfy the produced instantaneous impact of overhead wire of various models.
