Description

一种架空自承式光缆的保护环 An overhead self-supporting fiber optic cable protection ring

技术领域 FIELD

本发明涉及一种架空自承式光缆的保护环。 The present invention relates to a trolley self-supporting cable of the protective ring.

背景技术 Background technique

架空自承式光缆是在电力输电线路杆线上采用架空方式使用的光缆,由于该光缆在一定的电场强度范围内使用,特别在110KV、220KV线路上使用时光缆挂点电场强度常常在12KV-20KV之间,有些挂点的甚至到30KV以上,在这种情况下尤其在盐雾和污染严重的地区会经常发生电腐蚀损坏光缆。 Overhead Self-supporting cable for overhead embodiment is the use of cable used in power line pole transmission line, since the cable is used for a certain range of field strength, particularly in 110KV, 220KV line using the cable suspension point field intensity often 12KV- between 20KV, some even hanging points to 30KV or more, especially in the salt spray and polluted areas often galvanic corrosion damaged cable in this case. 因为光缆工作时处于导线周围空间存在的强大的电场中,光缆对导线和大地之间的耦合电容使之处于一个空间电位的位置,在空间电位的作用下,光缆表面的污垢或积水对接地的金具产生一个接地漏电流,该电流产生热量使光缆表面的水分蒸发,在水分蒸发过程中会随机地形成干燥带区阻断光缆表面的漏电流,当干燥带区两端的电位足够高时就会产生放电并形成电弧,该电弧会对光缆表面产生腐蚀甚至击穿或烧坏光缆。 Since a strong electric field in the space around the conductor cable when present work, coupling capacitance between the cable conductors and ground in a position to make a space potential, the potential under the effect of the space, cable or dirt on the surface of the ground water the fittings to produce a earth leakage current, which current generates heat moisture cable surface evaporation will randomly formed drying band blocking cable surface leakage current in the evaporation process, it is when the ends of the drying band potential is high enough discharge is generated to form an arc that would cause corrosion of the cable surface breakdown or even burn the cable. 目前国内外解决该问题的方法主要是控制光缆的挂点、采用不同的金具配套安装的方案,没有从根本上解决问题的有效措施。 Current methods at home and abroad to solve this problem is mainly linked to the control point fiber optic cable, using different fittings supporting the installation of the program, there is no effective measures to solve the problem fundamentally.

发明内容 SUMMARY

本发明为解决上述技术问题,提供一种能阻止在光缆表面产生放电现象的架空自承式光缆的保护环。 The present invention is to solve the above problems, there is provided a protective ring prevents the discharge phenomenon generated in the surface of the cable self-supporting overhead cables.

本发明是这样实现的:一种架空自承式光缆的保护环,它为套在光缆外表面的绝缘套管,所述套管由两个半管体采用对扣方式密封连接,半管体组合成套管时两端的内径稍小于光缆的直径,半管体的管体外表面至少设有一个径向向外凸起的半环体。 The present invention is implemented as follows: An overhead guard ring Self-supporting cable, which is set in the outer surface of the cable insulating sleeve, the sleeve body is made from two half tubes sealingly connected to the buckle, the half pipe when the inner diameter ends of the tube is slightly smaller than the diameter of the combination kit of the cable, the outer surface of the tube is provided with at least half of the tubular body a half-ring member projecting radially outwardly.

在本发明中所述半环体与半管体之间为平滑过渡,半环体外环缘呈弧形;所述两个半管体相结合的部位上对应设有多个螺纹通孔,螺纹通孔之间通过螺钉连接;所述套管的内孔为变径孔,变径孔的最小内径稍小于光缆的直径,所述螺纹通孔位于套管的最小内径部位。 Between the semi-ring half pipe is a smooth transition in the present invention, the half-rings in vitro curved rim; corresponding to a plurality of threaded through holes on the two half-tubes combining site, connected between by screws threaded through holes; inner bore of the sleeve is a stepped bore, a minimum inner diameter slightly smaller than the diameter of the stepped bore of the cable, the threaded through bore of the sleeve portion minimum inner diameter.

所述两个半环体相对的结合面为凹凸对接面;所述两个半管体内部在螺纹通孔的部位设有刚性垫片;所述套管为硅橡胶材料。 The two half-ring opposite the surface is a convex abutment surface binding; the interior of the tubular body is provided with two semi-rigid portion threaded through hole in the spacer; and the sleeve is a silicone rubber material.

采用上述结构后,半管体的管体外表面设有径向向外凸起的半环体,它就阻断了光缆表面的污染和水膜与接地的光缆金具之间的漏电流通路。 With the above structure, the outer surface of the tubular body is provided with a semi-tubular half-ring projecting radially outward, it blocks the flow passage between the leakage and contamination of the ground water film cable fittings of the cable surface. 即使有可能形成漏电流,由于半环体与半管体之间为平滑过渡,半环体外周面呈弧形,因此在保护环的环缘处最易形成干燥带区,即它能将干燥带区引至保护环的外环缘上,这样就会在保护环上放电。 Even if it is possible to form a leakage current due to the smooth transition, the arcuate peripheral surface of the half-rings in vitro half-ring between the tube body and half, so most likely to form at the drying zone with the rim of the guard ring, i.e., it can be dried band directed to the outer rim of the guard ring, so that it will discharge in the guard ring. 由于保护环为硅橡胶或者类似性能的材料,具有良好的绝缘和耐温性能,可防止放电电弧对保护环的损坏,从而有效地保护光缆。 Since the guard ring made of silicone rubber or similar material properties, has good insulation and heat resistance, arc discharge can be prevented damage to the guard ring, thus protecting the cable. 套管由两个半管体组成,可以方便地将保护环安装在光缆外表面。 Sleeve composed of two half tubes, the guard ring can be easily mounted on the outer surface of the cable. 套管内孔两端的直径稍小于光缆的直径,套管与光缆紧密连接,可阻止漏电流的形成。 Across the bore diameter slightly smaller than the inner diameter of the sleeve of the cable, sleeve and close connection cable, can be formed to prevent leakage current. 套管的内孔为变径孔,螺纹通孔位于套管的最小内径部位,安装方便可靠。 Reducing sleeve for bore holes, threaded through holes of the sleeve portion minimum inner diameter, convenient and reliable installation. 如果套管的内径整体都稍小于光缆直径,就需要很大的螺纹紧固力,安装就很费力,且不容易实现紧密结合和密封要求。 If the entire inner diameter of the sleeve are slightly smaller than the cable diameter, it requires a large screw tightening force, the installation is very laborious and not easy to achieve tight binding and sealing requirements. 两个半环体相对的结合面为凹凸对接面,结合紧密。 Two opposing half-ring abutting surface uneven surface binding, binding tightly. 半管体内部在螺纹通孔的部位设有刚性垫片,半管体之间的连接牢固可靠。 Semi-rigid tubular body provided inside the spacer portion of the threaded through bore, semi solid and reliable connection between the tubular body.
