Description
技术领域technical field
本发明涉及电力设备、输电线路减振技术领域，具体是指一种碰撞耗能间隔棒。The invention relates to the technical field of vibration reduction of power equipment and transmission lines, in particular to a collision energy-consuming spacer.
背景技术Background technique
随着我国对电量需求的增加，输电线路的档距、导线的分裂数等均呈增加趋势。输电线路在风荷载作用下的振动非常严重，根据导线振动频率的高低和振幅的大小，其大致可分为微风振动(高频率低振幅)、次档距振荡(中频率中振幅)和舞动(低频率高振幅)3种。输电线路振动可能造成断线、疲劳断股等危害，极大地威胁着输电线路的安全运行。为了减少导线振动给输电线路带来的危害，必须采取有效措施对其进行抑制。目前我国主要通过安装阻尼间隔棒、失谐摆等装置来实现其抑制导线振动的目的，但其减振效果有限。因此研发一种设计合理、减振效果明显的间隔棒，将有利于输电线路的安全运行，减少维护成本。As my country's demand for electricity increases, the span of transmission lines and the number of splits of conductors are all on the rise. The vibration of the transmission line under the wind load is very serious. According to the vibration frequency and amplitude of the conductor, it can be roughly divided into breeze vibration (high frequency and low amplitude), sub-gap vibration (medium frequency and medium amplitude) and galloping ( Low frequency high amplitude) 3 types. Vibration of transmission lines may cause hazards such as broken wires and strands due to fatigue, which greatly threatens the safe operation of transmission lines. In order to reduce the harm of conductor vibration to transmission lines, effective measures must be taken to suppress it. At present, our country mainly realizes the purpose of suppressing the vibration of the wire by installing damping spacers, detuned pendulums and other devices, but the vibration reduction effect is limited. Therefore, the development of a spacer with reasonable design and obvious vibration reduction effect will be beneficial to the safe operation of transmission lines and reduce maintenance costs.

具体实施方式detailed description
如图1、图2所示的一种碰撞耗能间隔棒，该间隔棒由质量球1、弹簧2、金属空心球3、金属圆管4、间隔棒框架5、线夹6及粘弹材料层7组成。A collision energy-dissipating spacer as shown in Figures 1 and 2, the spacer is composed of a mass ball 1, a spring 2, a metal hollow ball 3, a metal tube 4, a spacer frame 5, a wire clip 6 and a viscoelastic material Layer 7 composition.
金属空心球3为空心球体结构，四周与金属圆管4相连处开口，且与金属圆管4接头处做光滑处理以防止弹簧2卡住。质量球1、粘弹材料层7均位于金属空心球3内：质量球1在金属空心球3内呈悬吊状态，悬吊点位于金属空心球3的正中心；粘弹材料层7贴附式设置在金属空心球3的内壁上，从而起到吸收能量、耗能减振的作用。金属圆管4的另一端与间隔棒框架5固定连接。弹簧2位于金属圆管4及金属空心球3内，弹簧2的一端固定连接在间隔棒框架5上，弹簧2的另一端与质量球1连接。粘弹材料层7的材质优选为橡胶，所述质量球1、弹簧2、金属空心球3、金属圆管4、间隔棒框架5及线夹6的材质优选为钢材。The metal hollow ball 3 is a hollow sphere structure, and the surroundings are connected with the metal round pipe 4 with openings, and the joints with the metal round pipe 4 are smoothed to prevent the spring 2 from being stuck. Both the mass ball 1 and the viscoelastic material layer 7 are located inside the metal hollow ball 3: the mass ball 1 is suspended in the metal hollow ball 3, and the suspension point is located at the center of the metal hollow ball 3; the viscoelastic material layer 7 is attached It is arranged on the inner wall of the metal hollow ball 3, so as to play the role of energy absorption, energy consumption and vibration reduction. The other end of the metal circular tube 4 is fixedly connected with the spacer bar frame 5 . The spring 2 is located in the metal round tube 4 and the metal hollow ball 3 , one end of the spring 2 is fixedly connected to the spacer frame 5 , and the other end of the spring 2 is connected to the mass ball 1 . The material of the viscoelastic material layer 7 is preferably rubber, and the material of the mass ball 1 , the spring 2 , the metal hollow ball 3 , the metal tube 4 , the spacer frame 5 and the wire clamp 6 is preferably steel.
本实施例中的碰撞耗能间隔棒利用悬吊质量球1在外部荷载作用下发生摆动和碰撞等行为实现输电线路减振作用，具有设计合理、简单、经济、易于实施等优点。使用过程中，将碰撞耗能间隔棒安装在分裂导线上，当导线在地震动或风荷载作用下产生振动时将带动质量球1摆动，质量球1振动产生的惯性力反作用于输电线路本身，与输电线路自身运动方向相反，产生了减振作用，当外部荷载增加时，质量球1摆动幅度加大，将与在金属空心球3内壁布置的粘弹性材料发生碰撞，碰撞过程中粘弹性材料将吸收部分能量，间隔棒此阶段起到耗能作用。因此，当外部环境荷载较小时间隔棒起到减振作用，而当外部环境荷载较大时，间隔棒同时起到减振和耗能作用。因输电线路上几乎随时都在承受风荷载，而地震罕见发生，所以该碰撞耗能间隔棒在输电线路抗风问题上的应用更重要。The collision energy-dissipating spacer in this embodiment utilizes the behavior of the suspended mass ball 1 to swing and collide under external loads to realize the vibration reduction effect of the transmission line, and has the advantages of reasonable design, simplicity, economy, and ease of implementation. During use, the collision energy-dissipating spacer is installed on the split conductor. When the conductor vibrates under the action of earthquake or wind load, it will drive the mass ball 1 to swing, and the inertial force generated by the vibration of the mass ball 1 reacts on the transmission line itself. Opposite to the movement direction of the transmission line itself, the vibration reduction effect is produced. When the external load increases, the swing range of the mass ball 1 increases, and it will collide with the viscoelastic material arranged on the inner wall of the metal hollow ball 3. During the collision process, the viscoelastic material Part of the energy will be absorbed, and the spacer will consume energy at this stage. Therefore, when the external environmental load is small, the spacer rods play the role of vibration reduction, and when the external environmental load is large, the spacer rods play the role of vibration reduction and energy dissipation at the same time. Because the transmission line is under wind load almost at any time, and earthquakes rarely occur, so the application of the collision energy-dissipating spacer in the transmission line wind resistance problem is more important.
本实施例的质量球1、金属空心球3和金属圆管4设置时，需要注意的是：第一，质量球1的摆动频率应尽可能接近输电线路自振频率；第二，金属空心球3与质量球1之间的距离应根据需要确定；第三，金属空心球3与金属圆管4的连接处务必光滑，以避免弹簧2在运动过程中被卡住；第四，金属圆管4的直径要大于弹簧2直径，保证弹簧2在金属圆管4内可以自由伸缩；第五，要根据计算确定碰撞耗能间隔棒在输电线路上的位置及数量。When setting the mass ball 1, the metal hollow ball 3 and the metal round tube 4 in this embodiment, it should be noted that: first, the swing frequency of the mass ball 1 should be as close as possible to the natural frequency of the transmission line; second, the metal hollow ball 3 and the distance between the quality ball 1 should be determined according to the needs; third, the connection between the metal hollow ball 3 and the metal tube 4 must be smooth to avoid the spring 2 being stuck during the movement; fourth, the metal tube The diameter of 4 is greater than the diameter of spring 2 to ensure that spring 2 can freely expand and contract in the metal tube 4; the 5th, the position and quantity of the energy-dissipating spacer rods on the transmission line should be determined according to calculation.
作为本实施例的变换，粘弹材料层7的材质也可以采用其他粘弹性材料，如弹性树脂、皮革等，质量球1、弹簧2、金属空心球3、金属圆筒5、间隔棒框架5及线夹6的材质也可以采用铁或铜或金属合金。As a transformation of the present embodiment, the material of the viscoelastic material layer 7 can also adopt other viscoelastic materials, such as elastic resin, leather, etc., mass ball 1, spring 2, metal hollow ball 3, metal cylinder 5, spacer rod frame 5 And the material of wire clamp 6 also can adopt iron or copper or metal alloy.
本发明的上述实施例并不是对本发明保护范围的限定，本发明的实施方式不限于此，凡此种种根据本发明的上述内容，按照本领域的普通技术知识和惯用手段，在不脱离本发明上述基本技术思想前提下，对本发明上述结构做出的其它多种形式的修改、替换或变更，均应落在本发明的保护范围之内。The above-mentioned embodiments of the present invention do not limit the protection scope of the present invention.
