本申请提供的耐张联板过载发热分流装置，与现有技术相比，通过绝缘操作杆一与夹持部一的配合，实现对耐张接线管端导线的夹持，通过绝缘操作杆二与夹持部二的配合，实现对接线端子端导线的夹持，利用夹持部一及夹持部二间的分流线实现耐张接线管端导线与接线端子端导线的连通，有效增大耐张联板接触面积，减小耐张联板通过电流，进而有效降低耐张联板的负荷，可将耐张联板的高温降低70%。在同塔双回高压输电线路耐张联板发热后，通过带电安装旁路分流线，可带负荷在短时间内减小耐张联板的电阻电流产生的降温方法，根据分流线的所在位置通过地电位绝缘操作杆安装旁路分流线将耐张联板分流降低耐张联板的负荷，以此分流线为承载导线与耐张联板同时过流，降低问题耐张联板的电阻阻抗，同时在耐张联板异常时亦可作为后备。利用本申请能够实现在不影响线路负荷、不改变电网运行方式的情况下，进行耐张联板过热缺陷的过渡，可等到停电检修时使耐张联板得到检修，加强检修的计划性及时效性。
通过对过载发热的耐张联板分析可知，按照焦耳定理（Q＝I2Rt）来讲，时间－定的情况下发热必然是电流和电阻的共同作用，首先高负荷期间电流有所增加，发热必然是由于接触电阻过大造成。由此可得解决耐张联板发热的办法是；减小耐张联板接触电阻、增大有效接触面积，从而达到降低耐张联板温度的目的。本申请即是通过分流线为耐张联板进行分流，降低问题耐张联板的电阻阻抗，同时借助第一固定钳口增大耐张联板接触面积，减小耐张联板通过电流，从而降低耐张联板的温度。可使问题耐张联板坚持到停电检修时间，断电后再得以检修，耐张联板检修完毕，即可将夹持部一及夹持部二拆卸下来，方便下次循环利用。

另外，为了满足绝缘操作杆一及绝缘操作杆二在同一方向操作的目的，也可以采用蜗轮蜗杆传动或齿轮齿条传动，均能够实现传动方向的改变。
在一个实施例中，请参阅图1、2，作为本申请提供的耐张联板过载发热分流装置的一种具体实施方式，所述连接结构包括用于与所述锥齿轮二7的主轴5及所述第二丝杆18相连的轴套3，所述轴套3为一端开口的管状，所述轴套3内孔底部设有磁铁4，所述轴套3侧壁开设有与拴轴2上销钉19配合的L型豁口，所述拴轴2固定在所述绝缘操作杆一1及绝缘操作杆二15端部，所述L型豁口底部与所述磁铁4的距离等同于所述销钉19与所述拴轴2端部的距离。在绝缘操作杆一及绝缘操作杆二的端部安装带有销钉拴轴，通过旋转拴轴，使其侧面的销钉旋入轴套侧壁的L型豁口内，同时利用磁铁对拴轴进行吸附，设绝缘操作杆一及绝缘操作杆二在操作过程中更稳妥，避免从轴套内滑脱。
在一个实施例中，请参阅图1，作为本申请提供的耐张联板过载发热分流装置的一种具体实施方式，所述支架9通过法兰盘10固定在第一固定钳口13上。为了方便拆卸，可将支架固定在法兰盘上，再将法兰盘通过螺栓固定在第一固定钳口的外侧壁。
在一个实施例中，请参阅图1、2，作为本申请提供的耐张联板过载发热分流装置的一种具体实施方式，所述分流线12两端分别通过螺栓固定在所述第一固定钳口13及所述第二固定钳口16的侧面。分流线可采用25平方毫米个软铜线，将其两端缠绕在螺栓上，并通过螺栓将其端部压紧在第一固定钳口及第二固定钳口16的侧面，方便装卸及更换。
在一个实施例中，请参阅图1、2，作为本申请提供的耐张联板过载发热分流装置的一种具体实施方式，所述第一压板11中部设有与导线配合的凹槽，与第一压板11相对的第一固定钳口13侧壁上对应设有与导线配合的凹槽；所述第二压板17中部设有与导线配合的凹槽，与第二压板17相对的第二固定钳口16侧壁上对应设有与导线配合的凹槽。利用凹槽对导线的限位，可使处于高空的夹持部一及夹持部二准确地卡紧耐张接线管端及接线端子端的导线。
在一个实施例中，在本申请的一个具体实施例中，所述第一固定钳口13及所述第二固定钳口16的带有凹槽的侧壁外表面为弧形。通过此种结构可增强第一固定钳口及第二固定钳口的强度，避免在使用过程中第一固定钳口及第二固定钳口发生变形。
在一个实施例中，在本申请的一个具体实施例中，所述分流线12为铜线。借助铜线电阻小的特性，能够快速分流耐张联板上的电流。
本申请的操作过程如下：需由两人配合操作安装，操作时绝缘操作杆一及绝缘操作杆二必须同时进入电位，进电位前根据耐张铁塔转角的导线角度调整第一固定钳口及第二固定钳口的U型槽开口方向，通过旋转绝缘操作杆一及绝缘操作杆二，进而利用第一压板将耐张接线管端导线卡紧在第一固定钳口内，利用第二压板将接线端子端导线卡紧在第二固定钳口内，利用第一固定钳口与第二固定钳口间的分流线对耐张联板的电流进行分流，实现降低问题耐张联板温度的目的。可将本申请拓展到同塔多回线路带电检修领域，为及时消除线路缺陷进一步推广输电线路的状态检修，提高线路可用系数及企业的经济与社会效益必将起到更加积极作用。
随着社会发展对供电的可靠性要求越来越严格，对于同塔多回线路很难申请停电。采用本申请可使耐张联板异常温升进行快速降温、异常检
、检安排合理优化，防止故障范围扩大，降低故障发生几率，提高检修效率，保证供电安全。对提高输电线路的可用系数及提高周边电网的安全具有很大的社会经济效益。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
