架空配电线路 技术领域
本发明涉及架空线路技术领域，更具体地涉及一种架空配电线路。
背景技术
今年来随着配电网改造的启动，10kV架空绝缘线路系统逐步采用绝缘导线，与裸导线相比，绝缘导线具有优越的绝缘性能，能有效防止因外来物体引起的相间短路，提高线路安全供电的可靠率及电压质量，但是使用绝缘导线以来，雷击断线事故经常发生，威胁人身安全，造成巨大财产经济损失。为解决上述技术问题，目前主要通过加装避雷器或防雷绝缘子的方式进行一系列防雷措施，但是采用加装避雷器或防雷绝缘子的稳定性不佳，需要定期检测维护，消耗大量的人力成本。
发明内容
本发明的目的在于提供一种架空配电线路，能够降低现有配电网中雷击断线事故，提高防雷稳定性，降低检测维护的成本。

复合横担的中部水平固定于耐张杆上，复合横担的端部连接有耐张固定件，耐张固定件使两复合横担连接成一体，并且耐张固定件用于固定导线。
在配电网中，在耐张杆的同一水平面上固定有两个复合横担，当导线穿过耐张固定件固定时，两个复合横担能够共同承担线路所需的纵向张力，满足使用要求，进一步地，利用复合横担本体的复合化，能够大大增加干弧距离，提高电气耐雷水平，避免雷击断线闪络等事故，复合横担具有免维护性，无需定期检测和维护，大大降低人力成本，复合横担的使用还可以省略耐张绝缘子，简化线路结构。
其中，复合横担包括芯棒、套筒和硅橡胶伞裙，套筒和硅橡胶伞裙均包覆于芯棒的外周面，套筒包覆固定于芯棒的外周后，硅橡胶伞裙在芯棒上除套筒外的其他区域成型。
复合横担的外绝缘利用硅橡胶伞裙，具有良好的耐老化性能，电气性能稳定可靠，能够实现三十年全生命周期的免维护；同时，在硅橡胶伞裙包覆在芯棒之前，在芯棒上先套装一套筒，使得复合横担固定到耐张杆上时所承受的力作用在套筒上，从而可以避免对硅橡胶伞裙的损坏，防止外部湿气对芯棒的腐蚀。
其中，芯棒为玻璃纤维增强环氧树脂拉挤棒。
其中，芯棒为空心管或实心棒，芯棒的截面为矩形、圆形和多边形中的一种。
其中，还包括两顶相横担，顶相横担竖直固定于耐张杆远离地面的顶端，顶相横担的端部连接有顶相耐张固定件，顶相耐张固定件使两顶相横担连接成一体，顶相耐张固定件用于固定导线。
在耐张杆的顶部固定两顶相横担，与两复合横担一起可形成单回路三相耐张配网线路，线路结构稳定可靠，耐雷击水平高。
其中，顶相横担为复合绝缘子。
其中，耐张固定件上固定有针式绝缘子，针式绝缘子位于两复合横担的中间且用于支撑导线。
其中，耐张固定件包括角钢、位于角钢两侧的第一线夹和第二线夹、以及设置于角钢上的两抱箍，角钢与两抱箍相配合使两复合横担连接成一体，第一线夹和第二线夹用于固定导线。
其中，复合横担的端部固定有端部金具，两抱箍分别套装于两复合横担对应的端部金具后与角钢固定连接。
将耐张固定件固定在复合横担的端部金具上，能够避免对复合横担本体的损坏，避免湿气对复合横担本体的腐蚀。
其中，复合横担通过一固定装置固定于耐张杆上，固定装置包括横担容置件、杆体连接件和连接板，横担容置件包覆固定于复合横担上，杆体连接件固定于耐张杆上，连接板位于复合横担和耐张杆之间，连接板用于 固定横担容置件和杆体连接件。
其中，横担容置件为两U型抱箍，两U型抱箍分设于耐张杆的两侧，杆体连接件为四个螺栓，连接板上设有与两U型抱箍对应的第一安装孔、以及与四个螺栓对应的第二安装孔；
两复合横担水平架设在耐张杆上时，每一复合横担对应两U型抱箍和连接板，两复合横担共用四个螺栓，两U型抱箍穿过连接板上的第一安装孔使复合横担固定在连接板上，四个螺栓对应穿过耐张杆两侧的连接板使两复合横担同时固定在耐张杆上。
通过这种方式，两复合横担共用一杆体连接件，能够大大简化固定装置，降低施工复杂度，有利于快速将复合横担安装至耐张杆上。

具体实施方式
根据要求，这里将披露本发明的具体实施方式。然而，应当理解的是，这里所披露的实施方式仅仅是本发明的典型例子而已，其可体现为各种形式。因此，这里披露的具体细节不被认为是限制性的，而仅仅是作为权利要求的基础以及作为用于教导本领域技术人员以实际中任何恰当的方式不同地应用本发明的代表性的基础，包括采用这里所披露的各种特征并结合这里可能没有明确披露的特征。
实施方式一：
请一起参阅图1-图6。如图1所示，该架空配电线路10包括耐张杆101、两复合横担102和耐张固定件103；复合横担102的中部水平固定于耐张杆101上，复合横担102的端部连接有耐张固定件103，耐张固定件103使两复合横担102连接成一体，并且耐张固定件103用于固定导线。
具体地，复合横担102的中部水平固定于耐张杆101上，使得复合横担102的两个端部10211/10212均为自由端，这里的中部并非一定指复合横担102的正中间，而是指除两个端部10211/10212外的其他区域，这样固定的好处在于能够利用一个复合横担102实现两相导线的固定。
两复合横担102固定于耐张杆101上呈现的状态是这两个复合横担102在同一水平面上平行，且分别位于耐张杆101的两侧，两复合横担102位于耐张杆101同一侧的端部10211/10212同时连接有耐张固定件103，耐张固定件103使两个复合横担102连接为一个整体，呈矩形状，两端的耐张固定件103用于固定导线，能够实现两相导线的固定。
通过这种方式，在耐张杆101的同一水平面上固定有两个复合横担102，当导线穿过耐张固定件103固定时，两个复合横担102能够共同承担耐张线路所需的纵向张力，满足使用要求，进一步地，利用复合横担102本体的复合化，能够大大增加干弧距离，提高电气耐雷水平，避免雷击断线闪络等事故，复合横担102具有免维护性，无需定期检测和维护，大大降低人力成本，复合横担102的使用还可以省略耐张绝缘子，也就是说在 复合横担102和耐张固定件103之间，或者是说在复合横担102和导线之间没有耐张绝缘子，简化线路结构。
在本实施方式中，如图2所示，复合横担102包括芯棒1021、套筒1022和硅橡胶伞裙1023，套筒1022和硅橡胶伞裙1023均包覆于芯棒1021的外周面，套筒1022包覆固定于芯棒1021的外周后，硅橡胶伞裙1023在芯棒1021上除套筒1022外的其他区域成型，芯棒1021暴露在外的端部上固定有端部金具，后续会具体介绍。
具体地，芯棒1021为矩形的实心棒，通过玻璃纤维增强环氧树脂拉挤而成。矩形芯棒1021的外周为圆弧状，避免受力集中的影响，该芯棒1021相比同等截面积的圆形芯棒1021来说可以降低材料成本，抗弯性能好。当然可以理解，在其他实施方式中，芯棒1021也可为空心管，芯棒1021截面也可以是圆形或多边形。
复合横担102的外绝缘利用硅橡胶伞裙1023，具有良好的耐老化性能，电气性能稳定可靠，能够实现近三十年全生命周期的免维护，但是这种硅橡胶伞裙1023在长期受力的情况下容易发生损坏，使得湿气进入腐蚀芯棒1021，因此，本实施方式中的芯棒1021在包覆硅橡胶伞裙1023之前，先在芯棒1021上套装一套筒1022，可利用压接或胶装方式固定，套筒1022胶装在芯棒1021上后，可在套筒1022的两侧分别一体注射硅橡胶伞裙1023。
套筒1022可选为金属套筒1022，如钢管等。
通过这种方式，当复合横担102的中部固定到耐张杆101上时，可使承受的力作用在位于中部的套筒1022上，从而避免对硅橡胶伞裙1023的损坏。
在本实施方式中，如图3所示，耐张固定件103包括角钢1031、位于角钢1031两侧的线夹1032和线夹1033，以及设置于角钢1031上的两个抱箍1034，角钢1031与两个抱箍1034相配合使两个复合横担102连接成一体，线夹1032和线夹1033用于固定导线。
复合横担102的端部固定有端部金具1024，端部金具1024可选为一端开口的金属套筒或其他类似套筒的机构，如图4所示，本实施方式中， 端部金具1024为一端设有开口10241的金具，开口10241套装至芯棒1021端部10211或端部10212上，开口10241的另一侧设有绑线槽10242，如有需要可进行绑线，提高该端部金具1024的使用广泛性。
如图5所示，耐张固定件103与端部金具1024固定时，将两个抱箍1034分别套装在端部金具1024后，抱箍1034与角钢1031通过螺栓固定连接，可以看出，角钢1031和抱箍1034配合固定在端部金具1024的外周，能够避免对硅橡胶伞裙1023的损坏，避免湿气对芯棒1021的腐蚀。通过这种方式，使耐张固定件103固定在复合横担102上，使两个复合横担连接为一体，共同承担耐张固定件103上导线的纵向张力。
本实施方式中，耐张固定件103的角钢1031上还固定有针式绝缘子1035，针式绝缘子1035位于两复合横担102的中间且用于支撑导线。
具体地，针式绝缘子1035可选为复合绝缘子、玻璃绝缘子或陶瓷绝缘子，针式绝缘子1035固定在耐张固定件103的上方，用于支撑导线从耐张杆101的一侧跨越到另一侧，避免导线的磨损和无向性。
在本实施方式中，请一起参阅图1和图6，复合横担102通过一固定装置106固定于耐张杆101上，固定装置106包括横担容置件1063、杆体连接件1061和连接板1062，横担容置件1063包覆固定于复合横担102上，杆体连接件1061固定于耐张杆101上，连接板1062位于复合横担102和耐张杆101之间，连接板1062用于固定横担容置件1063和杆体连接件1061，从而使复合横担102固定到耐张杆101上。
横担容置件1063包覆固定在复合横担102上，固定的位置在复合横担102的套筒1022上，套筒1022具有足够的强度来承受作用力，横担容置件1063的容腔的形状与芯棒1021形状相匹配，横担容置件1063可选为一体的结构，或包含多个不同的结构，只要能满足包覆在套筒1022上后与连接板1062固定连接即可。
连接板1062位于复合横担102和耐张杆101之间，连接板1062的形状适应于复合横担102和耐张杆101的形状，如本实施方式中，复合横担102的芯棒1021为矩形，连接板1062朝向复合横担102的一侧为平面板，在其他实施方式中，如复合横担的芯棒为圆形，连接板朝向复合横担的一 侧可增设连接机构以适应芯棒的形状。耐张杆101的截面通常为圆形，因此连接板1062朝向耐张杆101的一侧设有弧形件10621，可增大连接板1062和耐张杆101的接触面积，提高固定的牢固性。
杆体连接件1061固定于耐张杆101上，可选类似抱箍的机构，套设在耐张杆101后与连接板1062进行连接，也可选贴附于耐张杆101的四周后与连接板1062固定连接，下面会详细介绍。实际安装中，由于两复合横担102需要在同一水平面上平行安装于耐张杆101上，因此杆体连接件1061通常可共用。
具体地，如图6所示，横担容置件1063为两U型抱箍1063，两U型抱箍1063分设于耐张杆101的两侧，能够均衡受力，杆体连接件1061为四个螺栓1061，螺栓1061的两端均设有螺纹，连接板1062上设有与两U型抱箍1063对应的安装孔10622、以及与四个螺栓1061对应的安装孔10623。
再次参阅图1，两复合横担102水平架设在耐张杆101上时，每一复合横担102对应两U型抱箍1063和连接板1062，两复合横担102共用四个螺栓1061，两U型抱箍1063穿过连接板1062上的安装孔10622使复合横担102固定在连接板1062上，四个螺栓1061对应穿过耐张杆101两侧的连接板1062上的安装孔10623，使两复合横担102同时固定在耐张杆101上。
通过这种方式，两个复合横担102共用一杆体连接件10621，能够大大简化固定装置106，降低施工复杂度，有利于快速将复合横担102安装至耐张杆101上。
本发明架空配电线路实施方式一通过在耐张杆101上水平固定两复合横担102，利用耐张固定件103将两个复合横担102连接成一体以共同承受纵向拉力，导线到达耐张杆时，经由耐张固定件一侧的线夹，由针式绝缘子支撑延伸至另一侧的线夹上，能够实现10kV或35kV配电网中耐张杆101的架设，这种方式的耐张杆101适用于空旷多雷的地区，相比防雷绝缘子或加装避雷器的防雷措施，电气稳定性高，无需定期检测和维护，能够避免雷击断线事故，降低人力成本。
实施方式二：
如图7所示，本实施方式的架空配电线路20包括：耐张杆201、两复合横担202和耐张固定件203；复合横担202的中部水平固定于耐张杆201上，复合横担202的端部连接有耐张固定件203，耐张固定件203使两复合横担202连接成一体，并且耐张固定件203用于固定导线。
另外，该架空配电线路20还包括两顶相横担204，顶相横担204竖直固定于耐张杆201远离地面的顶端，顶相横担204的端部连接有顶相耐张固定件205，顶相耐张固定件205使两顶相横担204连接成一体，顶相耐张固定件205用于固定导线。
具体地，两个顶相横担204固定在耐张杆201的顶部，呈现的状态是在同一竖直面内平行且位于耐张杆201向上延伸的两侧，两个顶相横担204的端部同时连接有顶相耐张固定件205，顶相耐张固定件205使两个顶相横担204连接成一个整体，呈矩形状，顶相耐张固定件205用于固定导线。
上述两个顶相横担204与两个复合横担202一起可形成耐张杆的单回三相导线的布设，例如，位于两个顶相横担204上的顶相耐张固定件205可实现中相导线的固定，位于两个复合横担202两端的两个耐张固定件203可实现边相导线的固定，线路结构稳定可靠，耐雷击水平高。
上述顶相横担104可选为复合绝缘子104，该复合绝缘子104为芯棒外套硅橡胶伞裙的结构，芯棒可通过玻璃纤维增强环氧树脂拉挤而成，可选为圆形实心芯棒。当然，可以理解的是，在其他实施方式中，该芯棒也可选为空心管，芯棒的截面也可为矩形。
顶相耐张固定件205与实施方式一的耐张固定件103结构相似，如图8所示，不同之处在于，顶相耐张固定件205上角钢2051的安装孔数量和位置有所不同，适应复合绝缘子204的金具结构，两者相互配合实现固定连接。
本实施方式中，两复合绝缘子204通过抱箍机构207连接在耐张杆201的顶端。抱箍机构207能够套装在耐张杆201上，抱箍机构207的顶端设有耳片2071，耳片2071上设有两个安装孔2072，复合绝缘子204的端部 金具为螺杆(图中未示出)，螺杆穿过安装孔2072后利用螺母紧固，通过这种方式，可以使两个复合绝缘子204固定在一个耳片2071上。
实施方式三：
请一起参阅图10和图11，本实施方式的架空配电线路30包括：耐张杆301、两复合横担302和耐张固定件303；复合横担302的中部水平固定于耐张杆301上，复合横担302的端部连接有耐张固定件303，耐张固定件303使两复合横担302连接成一体，并且耐张固定件303用于固定导线。
该架空配电线路30还包括两顶相横担304，顶相横担304竖直固定于耐张杆301远离地面的顶端，顶相横担304的端部连接有顶相耐张固定件305，顶相耐张固定件305使两顶相横担304连接成一体，顶相耐张固定件305用于固定导线。
在本实施方式中，复合横担302通过一固定装置307固定于耐张杆301上，固定装置307包括横担容置件3073、杆体连接件3071和连接板3072，横担容置件3073包覆固定于复合横担302上，杆体连接件3071固定于耐张杆301上，连接板3072位于复合横担302和耐张杆301之间，连接板3072用于固定横担容置件3073和杆体连接件3071，从而使复合横担302固定到耐张杆301上。
具体地，横担容置件3073为两U型抱箍3073，两U型抱箍3073分设于耐张杆301的两侧，杆体连接件3071为四个螺栓3071，连接板3072上设有与两U型抱箍3073对应的安装孔3075、以及与四个螺栓3071对应的安装孔3076。
与实施方式一中固定装置106不同的是，该固定装置307的连接板3073上还设有支撑平板3074，支撑平板3074上设有安装孔3077，安装孔3077与顶相横担304的端部金具3041相对应，用于将顶相横担304固定在支撑平板3074上。
通过这种方式，利用一连接板3073可实现复合横担303和顶相横担304的固定，简化固定装置307，便于安装。
为了更详细地说明该固定装置307，下面以一具体的安装场景为例进 行说明：
首先，在将复合横担303架设至耐张杆301之前，可先将两个U型抱箍3073固定在复合横担302的套筒3021上，两个U型抱箍3073分设在耐张杆301的两侧以均衡受力，两个U型抱箍3073上分别设有螺纹，穿过连接板3072上的安装孔3075后利用螺母紧固，另一复合横担302为同样的方法，从而完成两个复合横担302与连接板3072的固定。
然后，将两个复合横担302水平架设至耐张杆301上，螺栓3071穿过两侧连接板3072上对应的安装孔3076后利用螺母紧固，完成两个复合横担302与耐张杆301的固定。
将顶相横担304安装在连接板3072的支撑平板3074上，利用螺栓紧固，同样的方法安装另一侧的顶相横担304。
通过上述方式完成该固定装置307的安装，可以理解的是，上述安装方法并非限定该固定装置307，该固定装置307还可有其他安装方法，例如，在架设至耐张杆301之前，可先将螺栓3071穿过两侧连接板3072上对应的安装孔3076后利用螺母紧固，完成两个复合横担302与螺栓3071的固定，然后将两个复合横担302套设在耐张杆301上。从安装过程可以看出，该固定装置307通过共用连接板3072完成复合横担302和顶相横担304的安装，通过共用螺栓3071完成两复合横担302的安装，明显简化安装流程，降低施工复杂度。

将这两个复合横担402定义为一组复合横担402，将该组复合横担402在耐张杆401上复制依次排布，形成三组复合横担402，每组复合横担402的两个端部连接有耐张固定件403，也就是说，该架空配电线路40还包括另外两组的复合横担402、以及对应的耐张固定件403，能够实现同杆双回六相导线的布设。
当然，可以理解的是，在其他实施方式中，每组复合横担的长度和截面尺寸可不同，根据实际需要进行选择。
