Description
技术领域technical field
本实用新型涉及一种35kV电缆登杆装置，特别涉及一种全绝缘35kV电缆登杆装置，属于高压电缆登杆装置领域。The utility model relates to a 35kV cable climbing rod device, in particular to a fully insulated 35kV cable climbing rod device, which belongs to the field of high voltage cable climbing rod devices.
背景技术Background technique
35kV架空线路幅员辽阔、输送功率大，是配网输电的脊梁骨。由于35kV电压等级导线额定电压高，如同样采用10kV绝缘导线制造工艺在裸导线表面加绝缘层，导线重量将成倍增长，导致输电线路绝缘子抗弯强度、电杆抗拉强度同步成倍增长，从而造成目前架空输电线路结构无法承载的状态。正因为以上诸多原因，所以到目前为止，全国35kV及以上输电架空线路均仍采用裸导线。随着农村城镇化建设不断推进，原35kV架空输电线路旁出现大量道路基础建设、施工工地及高层建筑，从而造成近年来由于施工机具、高层抛物、风筝、气球等碰撞35kV架空裸导线引起触电、短路、跳闸等影响人身及输电安全的事故时有发生。给人民生活和电网安全带来重大危害。The 35kV overhead line has a vast territory and a large transmission power, and it is the backbone of the distribution network transmission. Due to the high rated voltage of the 35kV voltage level wire, if the same 10kV insulated wire manufacturing process is used to add an insulating layer to the surface of the bare wire, the weight of the wire will double, resulting in a double increase in the bending strength of the transmission line insulator and the tensile strength of the pole. As a result, the current overhead transmission line structure cannot bear the load. Because of the above reasons, so far, the national 35kV and above transmission overhead lines still use bare conductors. With the continuous advancement of rural urbanization, a large number of road infrastructure, construction sites and high-rise buildings have appeared next to the original 35kV overhead transmission line, which has caused electric shock, Accidents such as short circuit and tripping that affect personal safety and transmission safety occur from time to time. It will bring great harm to people's life and power grid security.
目前，35kV电缆登杆常规装置结构是：杆顶为上地线，依次往下为三相架空裸导线、裸露下引线、横担支架、绝缘子、避雷器及其安装平台和地下电缆接头固定架。电力通过三相架空裸导线从电源侧传输过来，经过线夹、裸露下引线连接到电缆接头、地下电缆，最终输送到用户。为了确保供电安全，中间必须用绝缘子加以支撑起到绝缘和连接作用，同时也必须配置避雷器，预防过电压对地下电缆的损害。从该结构方案看，35kV电缆登杆架空线路和地下电缆之间的连接方式属于敞开式结构。该敞开式电缆登杆装置离地较近，这一传统结构对于高层抛物、风筝、气球、蛇类等的防护能力较差，也容易造成裸露下引线与普通柱式避雷器的接线端子因异物碰线而导致短路跳闸，从而影响输电线路的安全可靠运行，而且由于一条35kV架空输电线路需给多条10kV输电线路输电，所以一旦一条35kV输电线路受损会造成社会及经济极大影响。At present, the structure of the conventional installation for 35kV cable climbing poles is: the top of the pole is the upper ground wire, followed by three-phase overhead bare wires, exposed lower leads, cross-arm brackets, insulators, lightning arresters and their installation platforms, and underground cable joint fixing frames. Power is transmitted from the power supply side through three-phase overhead bare wires, connected to cable joints and underground cables through clamps, exposed lower leads, and finally delivered to users. In order to ensure the safety of power supply, insulators must be used in the middle to support insulation and connection, and lightning arresters must also be configured to prevent damage to underground cables caused by overvoltage. Judging from the structural scheme, the connection mode between the 35kV cable boarding pole overhead line and the underground cable belongs to an open structure. The open cable climbing pole device is relatively close to the ground. This traditional structure has poor protection against high-rise parabolic objects, kites, balloons, snakes, etc., and it is also easy to cause the exposed lower lead wires to collide with the terminals of ordinary post arresters due to foreign objects. The short-circuit tripping of the line will affect the safe and reliable operation of the transmission line, and because a 35kV overhead transmission line needs to transmit power to multiple 10kV transmission lines, once a 35kV transmission line is damaged, it will cause great social and economic impact.

The new fully insulated 35kV cable pole installation includes poles and three-phase cables, and the three-phase cables are fixed and erected on the poles through strain-resistant clamps. The tension clamp is covered with a tension clamp insulation cover, and the upper end to the lower end of the pole is provided with a cross-arm bracket for the lower lead of the three-phase cable in turn. The cross-arm bracket includes a cross-arm insulator and a cross-arm base frame. Fixed on the pole, the cross-arm insulator is fixed on the cross-arm base frame, and the cross-arm insulator is covered with a cross-arm insulation cover, and the lower lead of the three-phase cable is electrically connected to the cross-umbrella cable joint through the cross-arm insulator.

The grounding ring is covered with an insulating cover of the grounding ring, and the upper lead end of the column type arrester is covered with an insulating cover of the arrester. connect. On the basis of the traditional bare wires, the above scheme achieves the purpose of improving the overall insulation performance of the device by adding full-covering insulating parts on the high-voltage cables and related components, and solves the problem of poor insulation performance of 35kV and above high-voltage lines, avoiding resulting in safety accidents.
架空线路绝缘化概念已经提出了较长时间，在10kV输配电架空线路上得到了广泛应用，也取得了比较理想的效果，但是在35kV输配电架空线路上的应用还处于摸索阶段。这主要是因为10kV输配电架空线路用的常规结构型式的绝缘罩在35kV输配电架空线路应用时有几个难点：一是由于运行电压的提高，要达到安全的绝缘性能，绝缘罩的厚度就要增加，随之而来的就是成本的增加和架空线路重量的大幅度增加，引起一连串的后续问题。二是随着电压的升高，发生沿面闪络的可能性远远大于击穿闪络，常规结构的绝缘罩不能满足这方面的要求。现有的10kV架空线路使用的绝缘套管是一个截面呈“Ω”形的开口套管结构，通过开口处的销钉旋紧锁闭。这种结构应用在35kV输电架空线路上的一个突出的问题就是绝缘套管的搭边较短，容易发生沿面闪络。为了解决这个问题，本方案采用了“回”形迷宫式绝缘套管。The concept of overhead line insulation has been proposed for a long time, and it has been widely used on 10kV transmission and distribution overhead lines, and has achieved relatively ideal results, but the application on 35kV transmission and distribution overhead lines is still in the exploration stage. This is mainly because the insulation cover of the conventional structure type used for 10kV transmission and distribution overhead lines has several difficulties in the application of 35kV transmission and distribution overhead lines: First, due to the increase in operating voltage, to achieve safe insulation performance, the insulation cover Thickness is about to increase, which is accompanied by an increase in cost and a substantial increase in the weight of overhead lines, causing a series of subsequent problems. Second, as the voltage increases, the possibility of flashover along the surface is far greater than that of breakdown flashover, and the insulating cover with conventional structure cannot meet the requirements in this respect. The insulating bushing used in the existing 10kV overhead line is an open bushing structure with an "Ω"-shaped cross section, which is screwed and locked by a pin at the opening. A prominent problem when this structure is applied to 35kV transmission overhead lines is that the overlapping edges of the insulating bushings are short, which is prone to flashover along the surface. In order to solve this problem, this scheme adopts the "back" shape labyrinth insulating sleeve.

The insulating bushing unit as a whole is a bushing structure with side openings along the axial direction. One end of the integral side opening of the insulating bushing unit is provided with an integral wrapping armor of the insulating bushing unit, and the other end of the integral side opening of the insulating bushing unit is provided with The overall wrapping of the insulating bushing unit B, the integral wrapping B of the insulating bushing unit is folded and covered on the outer surface of the integral wrapping A of the insulating bushing unit along the edge of the integral wrapping A of the insulating bushing unit to form a "back"-shaped labyrinth The overall wrapping structure of the insulating sleeve unit.

The above-mentioned "back"-shaped wrapping structure increases the length of the inner surface of the insulating bushing, thereby extending the length of flashover along the surface, effectively improving the safety performance of the insulating bushing, and also overcoming the locking structure of the existing 10kV overhead line insulating bushing. The stress concentration at the hole reduces the mechanical properties of the structure and leads to the problem that the insulating sleeve is easy to crack. The above-mentioned "back"-shaped insulating hemming structure can be bonded with insulating glue to form a one-time closed structure, but this structure has poor maintainability and cannot be disassembled for maintenance. In order to solve this problem, this solution discloses the above-mentioned anti-loosening bar structure to realize the firm combination of wrapping, this continuous pressing structure makes the packaging operation of the insulating sleeve similar to the zipper process, which not only has the convenience of operation, but also improves the sealing performance of the package, and at the same time the package structure is stable and not easy to crack and fall off , thereby improving the maintainability of the "back"-shaped labyrinth insulation wrapping structure, making installation and disassembly more convenient, and the casing body structure of the insulation casing is not changed.
为了满足35kV输电架空线路的绝缘全覆盖要求，本方案的绝缘套管采用了标准管套接的方案，即采用多根标准的绝缘套管相互首尾套接的方式实现线缆的全覆盖。为了实现上述技术目的，本方案的绝缘套管设计成可以首尾嵌套的方案，即首连接段的内径大于尾连接段的内径，绝缘套管单元整体包边乙的首连接段部分与绝缘套管单元整体包边甲的首连接段部分的内表面间设有尾连接段包边结构插槽腔，尾连接段包边结构插槽腔与绝缘套管单元的首连接段部分的内管腔形成首连接段内腔整体，绝缘套管单元的尾连接段部分的自由端可插入首连接段内腔整体的自由端形成密封连通的插接结构。这种插接结构使得绝缘套管可以根据实际需要无限延长，拆装方便，提高了整体线路绝缘套管的可维护性。在实际使用中，由于外部环境因素的影响，诸如大风、强降水等，架空电缆处于摇摆不定的工作状态，基于上述插接的套管结构容易在频繁的无序运动中产生松动甚至脱离，为了解决这个问题，本方案还公开了加强插接稳定性的方案，即绝缘套管单元整体包边甲的首连接段部分上设有锁紧通孔结构，锁紧通孔结构内设有锁紧螺丝，锁紧螺丝与锁紧通孔结构内部形成内外螺纹连接，锁紧螺丝通过锁紧通孔结构旋入或旋出尾连接段包边结构插槽腔，锁紧螺丝旋入尾连接段包边结构插槽腔抵紧插接在尾连接段包边结构插槽腔内的尾连接段部分形成锁紧结构，锁紧螺丝旋出尾连接段包边结构插槽腔脱离插接在尾连接段包边结构插槽腔内的尾连接段部分形成可拆卸的插接结构。锁紧通孔结构的引入加强了相邻套接的绝缘管的连接稳定性，同时便于拆卸，而且本方案的锁紧部件并不限于螺丝与螺纹的配合方式，还可以采用销钉拴紧的方式。In order to meet the requirements of full insulation coverage of 35kV transmission overhead lines, the insulating sleeve of this scheme adopts the scheme of standard tube socketing, that is, multiple standard insulating sleeves are socketed end-to-end to achieve full coverage of cables. In order to achieve the above-mentioned technical purpose, the insulating sleeve of this scheme is designed to be end-to-end nested, that is, the inner diameter of the first connecting section is larger than the inner diameter of the tail connecting section, and the insulating sleeve unit is integrally wrapped with the first connecting section of B and the insulating sleeve The inner surface of the first connecting section of the pipe unit as a whole is provided with a slot cavity of a tail connecting section wrapping structure, and the slot cavity of the tail connecting section is wrapped with the inner tube cavity of the first connecting section of the insulating sleeve unit. The inner cavity of the first connecting section is formed as a whole, and the free end of the tail connecting section of the insulating sleeve unit can be inserted into the free end of the inner cavity of the first connecting section to form a sealed and connected plug-in structure. This plug-in structure enables the insulating sleeve to be infinitely extended according to actual needs, and is convenient for disassembly and assembly, which improves the maintainability of the overall line insulating sleeve. In actual use, due to the influence of external environmental factors, such as strong winds, heavy precipitation, etc., the overhead cables are in a swaying working state, and the sleeve structure based on the above-mentioned plugging is easy to loosen or even detach during frequent disorderly movements. To solve this problem, this solution also discloses a solution to enhance the stability of plugging, that is, a locking through hole structure is provided on the first connecting section of the integral side armor of the insulating sleeve unit, and a locking through hole structure is provided in the locking through hole structure.

现有的10kV架空线路绝缘套管以及其改型的应用在35kV输电架空线路上的同类型产品的套管内壁与裸导线是直接接触的，在外部作用力的扰动下，电缆产生不规则的摆动，导致绝缘套管内壁与裸导线表面产生频繁的摩擦，从而产生从绝缘套管内部开始的磨损甚至开裂，最终导致绝缘失效。为了解决这个问题，本方案在绝缘管内部设置了环状加强筋，如图2和2-2所示，即绝缘套管单元的套管段内壁上沿轴向设有若干加强筋环，加强筋环的内径大于裸导线的外径。这种采用若干加强筋套住裸导线的方案不仅加强了绝缘管本身的机械性能，而且将裸导线与绝缘套管内壁隔离，使得绝缘管内壁与裸导线间产生间隙，不仅防止了两者间的摩擦，而且还有利于间隙内的空气对流散热。为了满足电缆绝缘的要求，同时兼顾架设结构的承受能力，本方案的绝缘套管对组成的材质和产品的尺寸进行了优化，即35kV输电架空线路迷宫式绝缘套管的材质是厚度大于或等于2.5mm的硅橡胶材料。硅橡胶的介电强度很高，1mm厚的硅橡胶就能承受20kV的耐压试验，实验证明只要把硅橡胶绝缘罩的厚度设计成2.5mm以上就能满足实际使用的需要，而这个厚度相当于10kV用绝缘罩厚度。The existing insulating bushing for 10kV overhead lines and its modification applied to 35kV overhead lines have the inner wall of the bushing in direct contact with the bare wire, and the cable will produce irregular wires under the disturbance of external force Swinging will cause frequent friction between the inner wall of the insulating sleeve and the surface of the bare wire, resulting in wear and even cracking from the inside of the insulating sleeve, eventually leading to insulation failure. In order to solve this problem, this scheme sets a ring-shaped reinforcing rib inside the insulating tube, as shown in Figure 2 and 2-2, that is, the inner wall of the casing section of the insulating sleeve unit is provided with several reinforcing rib rings in the axial direction, and the reinforcing rib The inner diameter of the ring is larger than the outer diameter of the bare wire. This scheme of using several reinforcing ribs to cover the bare wire not only strengthens the mechanical properties of the insulating tube itself, but also isolates the bare wire from the inner wall of the insulating sleeve, creating a gap between the inner wall of the insulating tube and the bare wire, which not only prevents the gap between the two. friction, but also conducive to air convection heat dissipation in the gap. In order to meet the requirements of cable insulation and take into account the bearing capacity of the erection structure, the insulating sleeve of this scheme optimizes the material and product size, that is, the material of the labyrinth insulating sleeve for 35kV transmission overhead lines is thicker than or equal to 2.5mm silicone rubber material. The dielectric strength of silicone rubber is very high. Silicon rubber with a thickness of 1mm can withstand a 20kV withstand voltage test. The experiment proves that as long as the thickness of the silicone rubber insulating cover is designed to be more than 2.5mm, it can meet the needs of actual use, and this thickness is quite The thickness of the insulating cover is used at 10kV.
