Description
本發明主要係有關於一種用於送電線路之附有避雷裝置的三連式耐張絕緣子裝置。The invention relates mainly to a three-connected tensile insulator device for a power transmission line with a lightning protection device.
為了將送電線絕緣支撐於電塔上，習知以來係使用有各種絕緣子裝置，並在絕緣子裝置所擔負的引張荷重較大的場合中，使用有如專利文獻1所示的二連式耐張絕緣子裝置或三連式耐張絕緣子裝置。又當雷擊中送電線時，由於可防止由絕緣子裝置的閃燃(flash over)所導致之送電線路的雷擊事故，因此亦普遍將避雷裝置安裝於絕緣子裝置上。In order to insulate and support the power transmission wire on the electric tower, various insulator devices have been conventionally used, and in the case where the tensile load of the insulator device is large, a two-connected tensile insulator as shown in Patent Document 1 is used. Device or three-connected tensile insulator device. Further, when the lightning strikes the electric wire, since the lightning strike of the power transmission line caused by the flash over of the insulator device can be prevented, the lightning protection device is generally mounted on the insulator device.
該避雷裝置係為如下裝置：將具有相對於系統的運轉電壓雖為高電阻，但相對於雷擊過電壓卻成為低電阻之非線性的電壓一電流特性的氧化鋅元件以串聯方式配置於容器內部並以外覆方式被覆其外側，同時將放電用電極安裝於前端上。其平常時雖未流通電流，但雷擊時卻利用氧化鋅元件的電壓一電流特性抑制在絕緣子裝置所產生的電壓，亦在短時間內阻斷繼電流(follow current)，因而不至於導致送電線路的事故。此避雷裝置為用於例如275kV之送電線路且長度為1m以上、重量為數10kg的大型裝置。The lightning protection device is a device in which a zinc oxide element having a high voltage and a current characteristic with respect to a lightning strike voltage but having a low resistance with respect to a lightning strike voltage is arranged in series in a container. The outer side of the cover is covered by the outer cover, and the discharge electrode is attached to the front end. Although the current does not flow in the normal time, the voltage-current characteristic of the zinc oxide element is used to suppress the voltage generated in the insulator device during lightning strike, and the follow current is blocked in a short time, so that the power transmission line is not caused. Accident. This lightning protection device is a large-scale device for a power transmission line of, for example, 275 kV and having a length of 1 m or more and a weight of 10 kg.
另一方面，關於二連式耐張絕緣子裝置或三連式耐張絕緣子裝置，為了在二連式或三連式的各連接式絕緣子上均勻地擔負引張荷重，而透過稱之為「軛鐵」的平板狀金屬零件支撐接地側與集電側(電流集中側)兩者。圖1為二連式耐張絕緣子裝置的俯視圖，係透過接地側的二連式軛鐵2與集電側的二連式軛鐵3平行地支撐2根連接式絕緣子1。各軛鐵在兩端上備有連接安裝孔4，且連接式絕緣子1係透過連桿5安裝於連接安裝孔4上。在二連式軛鐵2的中心部上形成有其他金屬零件安裝孔6以連結至電塔臂7。On the other hand, regarding the two-connected tensile insulator device or the three-connected tensile insulator device, in order to uniformly bear the tensile load on each of the two-connected or three-connected connected insulators, The flat metal part supports both the ground side and the current collecting side (current concentrated side). 1 is a plan view of a two-connected tensile insulator device, in which two connected insulators 1 are supported in parallel with a two-connected yoke 3 on the collector side through a two-way yoke 2 on the ground side. Each of the yokes is provided with a connection mounting hole 4 at both ends, and the connection insulator 1 is attached to the connection mounting hole 4 through the link 5. Further metal fitting mounting holes 6 are formed in the center portion of the two-connected yoke 2 to be coupled to the tower arm 7.
在圖2所示之三連式耐張絕緣子裝置的場合中，將在兩端部上備有連接安裝孔4之二片二連式軛鐵2以中央的連接安裝孔4為同軸而連結，藉此構成三連式軛鐵12，並經由連桿5將連接式絕緣子1安裝於該各連接安裝孔4。當電線振動或連接式絕緣子振動時，藉由2片二連式軛鐵2的作動而可自動調節成使均勻的引張荷重作用於3根連接式絕緣子1上。In the case of the three-connected tensile insulator device shown in FIG. 2, two two-piece yokes 2 provided with connection mounting holes 4 at both ends are connected coaxially with the central connection mounting hole 4, Thereby, the three-way yoke 12 is formed, and the connection insulator 1 is attached to each connection mounting hole 4 via the link 5. When the wire vibrates or the connected insulator vibrates, it can be automatically adjusted by the action of the two two-connected yokes 2 so that a uniform tensile load acts on the three connected insulators 1.
在將避雷裝置10安裝於如上述之二連式耐張絕緣子裝置的場合中，會考量到重量平衡而將避雷裝置10安裝於二連式軛鐵2的中央位置。又在將避雷裝置10安裝於三連式耐張絕緣子裝置的場合中，可將避雷裝置安裝於上述二連式耐張絕緣子裝置之中心軸上的方式，將避雷裝置安裝於三連式耐張絕緣子裝置之中心軸上的方法。然而，根據此考量來安裝避雷裝置時，如圖3所示，必須透過跨越2片二連式軛鐵的避雷裝置安裝金屬零件(避雷器安裝金屬零件)來固定避雷裝置。此時，上述2片二連式軛鐵2的作動便會受到以跛剖面線(hatching陰影線)所示之避雷裝置安裝金屬零件(避雷器安裝金屬零件)之基部的妨礙，而阻礙由2片二連式軛鐵2作動所產生之對連接式絕緣子的均勻張力荷重的調整機能，更且會對跨越2片二連式軛鐵2的避雷裝置安裝金屬零件(避雷器安裝金屬零件)或2片二連式軛鐵2施加不合理的負荷。When the lightning protection device 10 is attached to the two-type tensile insulator device as described above, the lightning protection device 10 is attached to the center position of the two-way yoke 2 in consideration of the weight balance. Further, when the lightning protection device 10 is attached to the three-connection tensile insulator device, the lightning protection device can be attached to the center axis of the two-connection tensile insulator device, and the lightning protection device can be attached to the three-connection tensile device. A method on the central axis of an insulator device. However, when the lightning protection device is installed in accordance with this consideration, as shown in FIG. 3, it is necessary to fix the lightning protection device by installing a metal component (a lightning arrester mounting metal part) through a lightning protection device that spans two two-connected yokes. At this time, the operation of the two-piece two-way yoke 2 is hindered by the base of the lightning protection device mounting metal part (the lightning arrester mounting metal part) shown by the hatching line (hatching hatching), and the two pieces are obstructed. The function of adjusting the uniform tension load of the connected insulator generated by the operation of the two-connected yoke 2, and mounting the metal parts (the arrester mounting metal parts) or the two pieces of the lightning protection device across the two two-connected yoke 2 The two-connected yoke 2 exerts an unreasonable load.
為了解決上述問題，如圖2所示可想出將避雷裝置10安裝於單側的二連式軛鐵2的中央位置，且將平衡配重11安裝於另一個二連式軛鐵2的方法。然而，在275kV用避雷裝置的例子中，如前所述避雷裝置10係重量為數十kg的極重重物，因此平衡配重11亦會成為相同程度的重物，而會有設備成本變高且在電塔上的安裝作業亦不容易等問題存在。此外，若省略平衡配重11則會在連桿或其他的連結金屬零件上增加因扭曲所伴隨的特殊負荷，會損及強度或耐久性因而不佳。In order to solve the above problem, as shown in FIG. 2, a method of attaching the lightning protection device 10 to the center position of the two-way yoke 2 on one side and attaching the balance weight 11 to the other two-connected yoke 2 can be conceived. . However, in the example of the 275 kV lightning protection device, as described above, the lightning protection device 10 is a very heavy object having a weight of several tens of kilograms, so that the balance weight 11 also becomes a heavy object of the same degree, and the equipment cost becomes high. And the installation work on the electric tower is not easy to wait for problems. Further, if the balance weight 11 is omitted, a special load due to the twist is added to the link or other connecting metal parts, which may impair the strength or durability.

本發明的目的在於提供一種解決上述習知的問題點，即便備有作為重量物的避雷裝置亦可達到平衡配重的輕量化，不會破壞重量平衡且不會損及三連式耐張絕緣子裝置之機能的附有避雷裝置之三連式耐張絕緣子裝置。It is an object of the present invention to provide a solution to the above-mentioned problems. Even if a lightning protection device is provided as a weight, the weight of the balance weight can be reduced, the weight balance is not broken, and the three-connection tensile insulator is not damaged. The function of the device is a three-connected tensile insulator device with a lightning protection device.
為了解決上述課題而完成的本發明之附有避雷裝置的三連式耐張絕緣子裝置的特徵在於由下述所構成：三連式耐張絕緣子裝置，將在兩端部上備有連接安裝孔之二片二連式軛鐵以中央的連接安裝孔為同軸而連結，藉此構成三連式軛鐵，並經由連桿將連接式絕緣子安裝於該各連接安裝孔；避雷裝置，透過從其中一片二連式軛鐵向中央的連接安裝孔之方向外伸的避雷器安裝金屬零件，而固持於三連式耐張絕緣子裝置的中心軸上附近；以及小型平衡配重，為了取得該避雷器安裝金屬零件之重量份量的平衡，而安裝於另一片二連式軛鐵或其外側的連桿上。The three-connected tensile insulator device with a lightning protection device according to the present invention, which is completed to solve the above problems, is characterized in that it is composed of a three-connection type tensile insulator device, and a connection mounting hole is provided at both end portions. The two two-piece yokes are coaxially connected by the central connecting mounting holes, thereby forming a three-connected yoke, and the connecting insulator is mounted to the connecting mounting holes via the connecting rod; the lightning protection device is transmitted through A two-connected yoke is mounted to the arrester in the direction of the central connecting mounting hole, and is fixed to the center axis of the three-connected tensile insulator device; and a small balance weight for obtaining the arrester mounting metal The weight of the parts is balanced and mounted on another two-joint yoke or a connecting rod on the outside.
尚且，可作成：在位於避雷裝置之相反側的三連式軛鐵兩外端的連桿與連桿之間處，安裝有與避雷裝置的前端電極之間形成放電間隙(discharge gap)之角形避雷器(arcing horn)的構造；或安裝避雷裝置以取代角形避雷器，並在兩側避雷裝置間形成放電間隙的構造。Furthermore, it is possible to form an angular arrester that forms a discharge gap with the front end electrode of the lightning protection device between the connecting rod and the connecting rod at the outer ends of the three-connected yoke on the opposite side of the lightning protection device. (arcing horn) structure; or a lightning protection device installed to replace the angular arrester and form a discharge gap between the lightning protection devices on both sides.
由於本發明之附有避雷裝置之三連式耐張絕緣子裝置為透過從其中一片二連式軛鐵向中央的連接安裝孔之方向外伸的避雷器安裝金屬零件，來將避雷裝置固定於三連式耐張絕緣子裝置的中心軸上附近，同時備有用以取得避雷器安裝金屬零件之重量份的平衡的小型平衡配重的構造，因此即使避雷裝置為數10kg的重物，仍不會破壞絕緣子裝置整體的平衡。由此可達到平衡配重的輕量化且不會破壞重量平衡，故亦不會在連結金屬零件上施加因扭曲所伴隨的特殊負荷。The three-connected tensile insulator device with the lightning protection device of the present invention fixes the lightning protection device to the triple connection by mounting metal parts through a lightning arrester extending from one of the two-connected yokes toward the central connecting mounting hole. In the vicinity of the center axis of the tensile insulator device, a small balance weight having a balance of the weight of the arrester mounting metal parts is provided. Therefore, even if the lightning protection device has a weight of 10 kg, the entire insulator device is not damaged. Balance. As a result, the weight of the balance weight can be reduced without compromising the weight balance, so that the special load accompanying the distortion is not applied to the joint metal part.
以下表示本發明之實施型態。The embodiment of the present invention is shown below.
圖4與圖5係表示本發明之實施型態，將在兩端上備有連接安裝孔4之二片二連式軛鐵2以中央的連接安裝孔4為同軸可彎曲地連接，藉此形成三連式軛鐵12。在此實施型態中，三連式軛鐵12之接地側與集電側皆為相同構造，係透過連桿5將連接式絕緣子1安裝於各連接安裝孔4上。在接地側的各二連式軛鐵2的中心部上形成有金屬零件安裝孔6，並經由其他的連桿13及金屬零件14連接於電塔臂15。同樣在集電側的二連式軛鐵2的中心部上亦形成有金屬零件安裝孔6，並經由其他的連桿16及金屬零件17連接有送電線18。4 and 5 are views showing an embodiment of the present invention, in which two two-piece yokes 2 provided with connection mounting holes 4 at both ends are coaxially and flexibly connected by a central connection mounting hole 4, whereby A triple yoke 12 is formed. In this embodiment, the ground side and the current collecting side of the triple yoke 12 have the same structure, and the connecting insulator 1 is attached to each of the connecting mounting holes 4 via the connecting rod 5. A metal component mounting hole 6 is formed in a central portion of each of the two-way yokes 2 on the ground side, and is connected to the tower arm 15 via another link 13 and a metal component 14. Similarly, a metal component mounting hole 6 is formed in the center portion of the two-way yoke 2 on the current collecting side, and the power transmission line 18 is connected via the other connecting rod 16 and the metal component 17.
在本實施型態中，避雷裝置10係透過避雷器安裝金屬零件20而固定於接地側的三連式軛鐵12。如前述，避雷裝置10自身係以串聯方式配置氧化鋅元件並以外覆方式被覆其外側，同時在前端安裝有電極。如圖6所示，避雷器(horn角形)安裝金屬零件20為以下構造：基部21以螺栓固定於其中一片二連式軛鐵2上，並以將其前端之避雷裝置安裝板部22向中央的連接安裝孔之方向外伸的方式而延長。藉由作成此種構造，可使作為重物之避雷裝置10固持於三連式耐張絕緣子裝置的中心軸上附近，且為了不阻礙三連式耐張絕緣子裝置之二片軛鐵2的作動，而不以跨越此等軛鐵的方式來安裝。此處三連式耐張絕緣子裝置的中心軸上附近係指：從三連式耐張絕緣子裝置的中心軸起，容許避雷裝置10之直徑程度的偏離。In the present embodiment, the lightning protection device 10 is fixed to the three-way yoke 12 on the ground side by the metal member 20 mounted on the arrester. As described above, the lightning protection device 10 itself is configured by arranging the zinc oxide element in series and covering the outside thereof in an overlying manner, and the electrode is attached to the tip end. As shown in FIG. 6, the arrester (horn angle) mounting metal part 20 has the following configuration: the base portion 21 is bolted to one of the two-connected yoke 2, and the lightning protection device mounting plate portion 22 at the front end thereof is centered. Extend by connecting the mounting holes in a direction that extends outward. By making such a configuration, the lightning protection device 10 as a heavy object can be held in the vicinity of the central axis of the three-connected tensile insulator device, and in order not to hinder the operation of the two yokes 2 of the three-connected tensile insulator device Instead of installing across such yokes. Here, the vicinity of the central axis of the three-connected tensile insulator device means that the diameter of the lightning protection device 10 is allowed to deviate from the central axis of the three-connection tensile insulator device.
然而，如上所述即使將避雷裝置10固持於三連式耐張絕緣子裝置的中心軸上附近，僅有避雷器安裝金屬零件20之重量份量亦會使單側之二連式軛鐵2的重量變重。因此在本發明中，在相反側之二連式軛鐵2或其外側的連桿5上安裝有小型平衡配重30以消除重量的不平衡，此小型平衡配重30係為例如鍍有鋅的鋼鐵製品，其重量僅為10kg左右，相較於圖2所示之習知平衡配重11為數10kg，其重量甚輕，因此製作成本變得低廉亦易於進行電塔上的安裝作業。如前述，以從三連式耐張絕緣子裝置的中心軸起稍偏離相反側的方式來安裝避雷裝置10，可達到小型平衡配重11的輕量化。However, as described above, even if the lightning protection device 10 is held in the vicinity of the center axis of the three-connected tensile insulator device, only the weight of the arrester mounting metal part 20 will change the weight of the one-sided two-way yoke 2 weight. Therefore, in the present invention, the small balance weight 30 is attached to the two-side yoke 2 on the opposite side or the link 5 on the outer side thereof to eliminate the weight imbalance, and the small balance weight 30 is, for example, plated with zinc. The steel product has a weight of only about 10 kg, which is 10 kg compared with the conventional balance weight 11 shown in Fig. 2. The weight is very light, so that the manufacturing cost becomes low and the installation work on the electric tower is easy. As described above, the lightning protection device 10 is attached so as to slightly deviate from the center axis of the three-connection tensile insulator device, and the weight of the small balance weight 11 can be reduced.
再者，在位於避雷裝置10之相反側的三連式軛鐵12的兩外端的連桿5與連桿5之間處，安裝有與避雷裝置10之前端電極之間形成放電間隙G的角避雷器40。然而此角避雷器40的安裝方法並未特別限定，可就其形狀進行種種變化，更且可安裝避雷裝置以取代角避雷器40。Further, at a position between the link 5 and the link 5 at the outer ends of the triple-connected yoke 12 on the opposite side of the lightning protection device 10, an angle at which the discharge gap G is formed with the front end electrode of the lightning protection device 10 is attached. Lightning arrester 40. However, the mounting method of the angle arrester 40 is not particularly limited, and various changes can be made in the shape thereof, and a lightning protection device can be installed instead of the angle arrester 40.
如此般所構成的本發明之附有避雷裝置之三連式耐張絕緣子裝置，與習知附有避雷裝置的絕緣子裝置相同點為下述：將3根連接式絕緣子1以三連式軛鐵12支撐，藉此使各連接式絕緣子1均勻地分擔引張荷重；以及當受到雷擊時，透過放電間隙G使衝擊電流(surge current)流至避雷裝置10，藉此避免絕緣子裝置的損壞或在角避雷器間的閃絡(flash over閃燃)等。然而如上所述，本發明附有避雷裝置的三連式耐張絕緣子裝置相較於習知製品，可透過極為輕量的小型平衡配重30來確保整體的重量平衡，並避免在連結金屬零件類處產生伴隨扭曲的負荷。因此，相較於習知之下可使製作成本變得低廉，亦易於進行電塔上的安裝作業。The triple-connected tensile insulator device with the lightning protection device of the present invention thus constituted is the same as the conventional insulator device with the lightning protection device: the three connected insulators 1 are triple-connected yoke 12 support, whereby each of the connected insulators 1 uniformly shares the tensile load; and when subjected to a lightning strike, a surge current is transmitted to the lightning protection device 10 through the discharge gap G, thereby avoiding damage or at the angle of the insulator device Flashover between flash arresters, etc. However, as described above, the three-connected tensile insulator device with the lightning protection device of the present invention can ensure the overall weight balance and avoid the joint metal parts by the extremely lightweight small balance weight 30 compared with the conventional products. The class produces a load that is accompanied by distortion. Therefore, the manufacturing cost can be made lower than in the prior art, and the mounting work on the electric tower can be easily performed.
以上所說明之實施型態中係將避雷裝置10安裝於連接式絕緣子1的接地側，惟亦可安裝於集電側。又，能夠將避雷裝置10安裝於接地側、集電側兩側。In the embodiment described above, the lightning protection device 10 is attached to the ground side of the connected insulator 1, but may be mounted on the collector side. Moreover, the lightning protection device 10 can be attached to both sides of the ground side and the collector side.
