Description
本發明係關於設有電力保險絲(fuse)的真空開閉器之保險絲安裝構造。The present invention relates to a fuse mounting structure of a vacuum shutter provided with a power fuse.
於第5圖示有習知的設有電力保險絲的真空開閉器。如圖所示，於框架31係橫向排列地配置有3相份的具有固定接點與可動接點(任一者皆未圖示)的真空斷路器32。真空斷路器32之可動接點側係經由絕緣連桿33而連結至裝設於操作軸34的操作桿(lever)35。於操作軸34係設有可動鐵芯36，藉由使該可動鐵芯36被電磁鐵37吸引而轉動操作軸34，驅動操作桿35，經由絕緣連桿33而使可動接點連接/分離於固定接點。In Fig. 5, there is a conventional vacuum shutter provided with a power fuse. As shown in the figure, a three-part vacuum circuit breaker 32 having a fixed contact and a movable contact (none of which is not shown) is disposed in the frame 31 in a lateral arrangement. The movable contact side of the vacuum circuit breaker 32 is coupled to an operating lever 35 mounted on the operating shaft 34 via an insulating link 33. A movable iron core 36 is provided on the operation shaft 34, and the movable iron core 36 is attracted by the electromagnet 37 to rotate the operation shaft 34, and the operation lever 35 is driven to connect/separate the movable contact via the insulating link 33. Fixed contact.
另一方面，固定接點側係導電連接至固定於框體(frame)31的固定側端子38，於固定側端子38與配置於背面側的主電路導體(未圖示)之間係連接有電力保險絲39。電力保險絲39係被插入在安裝於裝設金屬具40的保險絲保持件(fuse holder)41中，且從上部放上鎖裝板42而藉由螺絲(bolt)鎖定(例如，參照專利文獻1)。On the other hand, the fixed contact side is electrically connected to the fixed side terminal 38 fixed to the frame 31, and is connected between the fixed side terminal 38 and a main circuit conductor (not shown) disposed on the back side. Power fuse 39. The electric fuse 39 is inserted into a fuse holder 41 attached to the mounting metal fitting 40, and the lock plate 42 is placed from the upper portion and locked by a bolt (for example, refer to Patent Document 1). .
[先行技術文獻][Advanced technical literature]
[專利文獻][Patent Literature]
[專利文獻1]日本實公昭62-33451號公報(第1頁、第1圖)[Patent Document 1] Japanese Patent Publication No. 62-33451 (first page, first figure)
在如專利文獻1所示的習知真空開閉器之保險絲安裝構造中，係因應電力保險絲39之形狀而將保險絲保持件41之內側形狀形成曲面。電力保險絲39之導電部與保險絲保持件41內面部雖表面上看似以廣面積作面接觸，但實際上為複數個點接觸或線接觸，且因電力保險絲39和保險絲保持件41些微的形狀尺寸之差異和鎖緊之力道不同而使接觸部位並非一定，難以特定究竟於何部分接觸。因此，視情形會有於接觸部產生偏移而引起異常發熱之情形的問題。In the fuse mounting structure of the conventional vacuum shutter shown in Patent Document 1, the inner shape of the fuse holder 41 is curved in accordance with the shape of the power fuse 39. The conductive portion of the electric fuse 39 and the inner surface of the fuse holder 41 appear to be in surface contact with a wide area on the surface, but actually have a plurality of point contact or line contact, and are slightly shaped by the power fuse 39 and the fuse holder 41. The difference in size and the strength of the locking force make the contact area not constant, and it is difficult to specify exactly where the contact is. Therefore, depending on the situation, there is a problem that the contact portion is displaced to cause abnormal heat generation.
又，專利文獻1亦揭示有於電力保險絲之長度方向的兩端面具有端子板，且將端子板以螺絲旋緊於安裝金屬具而安裝的構造。為如上所述之形狀的電力保險絲雖可解決接觸部偏移的問題，但市面上販售的電力保險絲多為具有如第5圖之圓筒狀端子(帽蓋(cap))的電力保險絲，真空開閉器之電力保險絲也多採用帽蓋型(cap type)。從而，於使用帽蓋型電力保險絲的真空開閉器中，依然存有上述問題點。Further, Patent Document 1 also discloses a structure in which terminal plates are provided on both end faces in the longitudinal direction of the electric fuse, and the terminal plates are screwed to the mounting metal fittings. Although the power fuse having the shape described above can solve the problem of contact offset, most of the power fuses sold in the market are power fuses having a cylindrical terminal (cap) as shown in FIG. The power fuse of the vacuum switch also uses a cap type. Therefore, in the vacuum shutter using the cap type power fuse, the above problem still exists.
本發明係為了消除如上所述之問題點而實施者，其目的為獲得可以確實地執行保險絲保持件與電力保險絲間之接觸的真空開閉器之保險絲安裝構造。The present invention has been made in order to eliminate the above-described problems, and an object thereof is to obtain a fuse mounting structure of a vacuum shutter that can reliably perform contact between a fuse holder and a power fuse.
本發明之真空開閉器的保險絲安裝構造係包含內藏了固定接點與可動接點的真空斷路器，且具有串聯連接於導電連接至固定接點的固定側端子與連接至電源側的固定側主電路導體之間的電力保險絲，其特徵為：保持電力保險絲之兩端部而予以固定的保險絲保持件係具有保險絲夾，其係含有固定於電路側的固定部和從該固定部之兩端朝末端扇形擴展而立起且呈V字狀傾斜而對向的保險絲接觸部，電力保險絲係至少使抵接於保險絲接觸部的2處為導電接觸。The fuse mounting structure of the vacuum switch of the present invention comprises a vacuum circuit breaker having a fixed contact and a movable contact, and has a fixed side terminal connected in series to the fixed contact and a fixed side connected to the power supply side. A power fuse between main circuit conductors, wherein the fuse holder that holds the both ends of the power fuse and has a fuse holder has a fixing portion fixed to the circuit side and two ends from the fixing portion The fuse contact portion that rises toward the end fan shape and is inclined in a V-shape, and the power fuse is at least electrically contacted at two places that abut against the fuse contact portion.
依據本發明之真空開閉器的保險絲安裝構造，保持電力保險絲之兩端部而加以固定的保險絲保持件係具有包含了固定於電路側的固定部和從固定部之兩端朝末端擴展地豎立而成V字狀傾斜且相對向的保險絲接觸部的保險絲夾，電力保險絲由於至少使抵接於保險絲接觸部的2處為導電接觸，故在電力保險絲與保險絲夾部間之連接部中，由於至少可以使其於預先想定的2處確實接觸，故接觸電阻之差異少，而可獲得安定之導電接觸，且提供高可靠性的真空開閉器。According to the fuse mounting structure of the vacuum switch of the present invention, the fuse holder that holds the both ends of the power fuse and is fixed has a fixing portion that is fixed to the circuit side and that is erected from both ends of the fixing portion toward the end. a fuse clip that is inclined in a V-shape and faces the fuse contact portion, and the power fuse is electrically contacted at least at two places that abut against the fuse contact portion, so at least a connection portion between the power fuse and the fuse clip portion is at least It can be made to be surely contacted at two predetermined places, so that the difference in contact resistance is small, and a stable conductive contact can be obtained, and a high reliability vacuum switch can be provided.
以下，依據圖式而說明本發明第1實施形態之真空開閉器的保險絲安裝構造。第1圖為使用了第1實施形態之保險絲安裝構造的真空開閉器之正面圖，其係示有將前面側之面板(face plate)的一部份切開而可看見內部的狀態。第2圖為第1圖之側面圖。Hereinafter, a fuse mounting structure of a vacuum shutter according to a first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a front elevational view showing a vacuum shutter using the fuse mounting structure of the first embodiment, showing a state in which a part of a front side panel is cut away to see the inside. Fig. 2 is a side view of Fig. 1.
如第1圖及第2圖所示，於搭載在台車1的絕緣框體2內係排列配置有3相份的構成真空開閉器之主電路接點的真空斷路器(vacuum interrupter)3。真空斷路器3係於真空容器內內藏有固定接點4和可動接點5，固定桿6係從固定接點4導出至外部，可動稈7係從可動接點5導出至外部。固定桿6之前端側係連接至固定於絕緣框體2的固定側端子8；可動桿7之前端側係經由絕緣桿9而連結至一端固裝於轉動軸10的桿11。另外，可動桿7之中間部係經由可撓導體而連接於被固定在絕緣框體2的可動側端子12。As shown in FIG. 1 and FIG. 2, in the insulating housing 2 mounted in the bogie 1, three vacuum interrupters 3 constituting the main circuit contacts of the vacuum switch are arranged. The vacuum circuit breaker 3 has a fixed contact 4 and a movable contact 5 in a vacuum container, and the fixed rod 6 is led out from the fixed contact 4 to the outside, and the movable stalk 7 is led out from the movable contact 5 to the outside. The front end side of the fixed rod 6 is connected to the fixed side terminal 8 fixed to the insulating frame 2; the front end side of the movable rod 7 is coupled to the rod 11 fixed to the rotating shaft 10 at one end via the insulating rod 9. Further, the intermediate portion of the movable lever 7 is connected to the movable side terminal 12 fixed to the insulating housing 2 via a flexible conductor.
於真空斷路器3之下方配置有具有可動鐵芯13與電磁鐵14的電磁操作機構。若以電磁鐵14吸引可動鐵芯13則轉動軸10將會轉動，且連動而驅動桿11，該驅動力係傳送至絕緣桿(rod)9、可動桿7、可動接點5，且使兩接點4、5連接/分離。An electromagnetic operating mechanism having a movable iron core 13 and an electromagnet 14 is disposed below the vacuum circuit breaker 3. If the movable iron core 13 is attracted by the electromagnet 14, the rotating shaft 10 will rotate, and the rod 11 will be driven in conjunction with the driving force, which is transmitted to the insulating rod 9, the movable rod 7, the movable joint 5, and two Contacts 4, 5 are connected/separated.
於真空斷路器3的上方配置有：當流通有預定以上的電流時用以將電路遮斷的電力保險絲15，該保險絲係依各相使軸線朝向與固定側端子8之導出方向平行的方向。且，電力保險絲15之一方的保險絲端子15a(端子部)係經由固定於絕緣框體2的連接導體16而連接至固定側端子8。此外，另一側之保險絲端子15a係經由連接導體17而連接至固定側主電路導體18。固定側主電路導體18係由固定於台車1的支持構件19支持，於前端部設有與電源側主電路導體連接的接觸件20。此外，於各相之電力保險絲15之相間設有絕緣障板(barrier)21。A power fuse 15 for blocking the circuit when a predetermined current or more is supplied is disposed above the vacuum circuit breaker 3, and the fuse is oriented in a direction parallel to the direction in which the fixed-side terminal 8 is led, in accordance with each phase. Further, one of the fuse terminals 15a (terminal portion) of the power fuse 15 is connected to the fixed-side terminal 8 via the connection conductor 16 fixed to the insulating housing 2. Further, the fuse terminal 15a on the other side is connected to the fixed side main circuit conductor 18 via the connection conductor 17. The fixed-side main circuit conductor 18 is supported by a support member 19 fixed to the bogie 1, and a contact member 20 connected to the power supply-side main circuit conductor is provided at the front end portion. Further, an insulating barrier 21 is provided between the phases of the power fuses 15 of the respective phases.
另一方面，可動側端子12係連接至朝與固定側主電路導體18同方向導出且由支持構件19所支持的可動側主電路導體22，於其前端部係設有與負載側連接的接觸件23。On the other hand, the movable side terminal 12 is connected to the movable side main circuit conductor 22 which is led out in the same direction as the fixed side main circuit conductor 18 and supported by the support member 19, and has a contact with the load side at the front end portion thereof. Item 23.
電力保險絲15係依真空開閉器之容量而流通有數百安培以上之電量，故確實之電性連接是非常重要的。因此，固定電力保險絲15的保險絲保持件24係由：藉由螺絲而鎖緊在連接導體16及17的保險絲夾(clip)25，以及將電力保險絲15插入保險絲夾25而從上方按壓而予以固定的保險絲按壓件26構成。Since the electric fuse 15 has a capacity of several hundred amps or more depending on the capacity of the vacuum switch, it is very important to make electrical connection. Therefore, the fuse holder 24 of the fixed power fuse 15 is secured by a fuse 25 that is locked to the connection conductors 16 and 17 by a screw, and the power fuse 15 is inserted into the fuse clip 25 and pressed from above to be fixed. The fuse pressing member 26 is constructed.
本實施形態之真空開閉器係於上述保險絲安裝構造具有特徵，故以下即對於保險絲保持件24進行更詳細的說明。Since the vacuum switch of the present embodiment is characterized by the above-described fuse mounting structure, the fuse holder 24 will be described in more detail below.
第3圖(a)為保險絲保持件24之斜視圖。保險絲保持件24之保險絲夾25係使薄板銅帶於長邊方向呈U字狀地彎曲，且折彎的相對向面係以朝向開口端側扇形擴展的方式擴展形成為V字狀。U字狀之底面部係形成為平面而成為固定在電路側之連接導體16或17的固定部25a。將從固定部25a之兩端往末端扇形擴展而立起且呈V字狀傾斜而相對向的相對向部作為保險絲接觸部25b。於保險絲接觸部25b之一方的前端部係形成有向外側呈L字狀彎曲的扣止爪25c，另一方之前端部為將全體向外側彎曲的連接部25d。於固定部25a之中央係形成有安裝孔25e，於連接部25d則形成有螺絲孔25f。Fig. 3(a) is a perspective view of the fuse holder 24. The fuse holder 25 of the fuse holder 24 is formed such that the thin copper strip is bent in a U shape in the longitudinal direction, and the opposing surface of the bend is expanded in a V shape so as to expand in a fan shape toward the opening end side. The U-shaped bottom surface portion is formed in a flat surface and is a fixing portion 25a that is fixed to the connection conductor 16 or 17 on the circuit side. The opposing portion that is fanned out from the both ends of the fixing portion 25a and extended in a fan shape and inclined in a V shape is used as the fuse contact portion 25b. The front end portion of one of the fuse contact portions 25b is formed with a locking claw 25c that is bent outward in an L shape, and the other front end portion is a connecting portion 25d that bends the entire outer side. A mounting hole 25e is formed in the center of the fixing portion 25a, and a screw hole 25f is formed in the connecting portion 25d.
另一方面，保險絲按壓件26係使薄板銅帶之中央部微微彎曲，於一側端部設有與保險絲夾25之扣止爪25c扣合的扣合孔26a，於另一側端部則設有與保險絲夾25之螺絲孔25f對合的安裝孔26b。On the other hand, the fuse pusher 26 slightly bends the central portion of the thin copper strip, and has a snap hole 26a that is engaged with the latching claw 25c of the fuse clip 25 at one end, and the other end is provided at the other end. A mounting hole 26b that is engaged with the screw hole 25f of the fuse holder 25 is provided.
該保險絲按壓件26的形狀和尺寸係被設計為當與保險絲夾25組合時，以可將插入保險絲夾25的電力保險絲15按壓至保險絲接觸部25b之方式予以加壓。The fuse holder 26 is shaped and sized to be pressurized in such a manner as to be able to press the power fuse 15 inserted into the fuse holder 25 to the fuse contact portion 25b when combined with the fuse holder 25.
又，保險絲按壓件26之材料雖說明為薄板銅帶，但並沒有特別使其功能為導電部的需要，故亦可使用鋼材。Further, although the material of the fuse holder 26 is described as a thin copper strip, it is not particularly required to function as a conductive portion, and therefore a steel material can be used.
其次，對於保險絲保持件24之作用進行說明。Next, the action of the fuse holder 24 will be described.
第3圖(b)為示有於保險絲夾25插入電力保險絲15，將保險絲按壓件26壓下且藉由螺絲或螺栓等鎖定構件27予以鎖緊之狀態的圖。由於保險絲接觸部25b係形成V字狀開放的直線，故於裝設有電力保險絲15時，保險絲接觸部25b之內面與電力保險絲15之保險絲端子15a係於2處接觸點接觸而成為通電接觸部。當然，雖於保險絲按壓件26側也會接觸，但至少必有2處之接觸點為接觸。且，該2處為依據保險絲端子15a之直徑與保險絲夾25之形狀而可計算預估之點，不會因組裝誤差等而有大幅變異。Fig. 3(b) is a view showing a state in which the fuse holder 25 is inserted into the power fuse 15, and the fuse presser 26 is pressed down and locked by a lock member 27 such as a screw or a bolt. Since the fuse contact portion 25b is formed in a V-shaped open straight line, when the power fuse 15 is mounted, the inner surface of the fuse contact portion 25b is in contact with the fuse terminal 15a of the power fuse 15 at two contact points to be energized. unit. Of course, although the fuse pressing member 26 side is also in contact, at least two contact points must be in contact. Further, the two points are calculated based on the diameter of the fuse terminal 15a and the shape of the fuse clip 25, and there is no significant variation due to assembly errors and the like.
從而，依據此保險絲保持件24可以獲得安定的導電接觸。Thus, a stable conductive contact can be obtained in accordance with this fuse holder 24.
於第4圖示有保險絲保持件之另一例。第4圖為相當於第3圖(b)之部分的剖面圖。Another example of a fuse holder is shown in Fig. 4. Fig. 4 is a cross-sectional view corresponding to a portion of Fig. 3(b).
與第3圖相同之點為，係以下列構件構成：將薄板銅帶於長邊方向彎曲為U字狀，且使相對向面以朝開口端側扇形擴展的方式擴展成V字狀而形成的保險絲夾28；以及保險絲按壓件29。以下則以相異點為中心進行說明。In the same manner as in the third embodiment, the thin copper plate is bent in a U shape in the longitudinal direction, and the opposing surface is expanded in a V shape so as to expand toward the opening end side. a fuse clip 28; and a fuse press member 29. The following is a description centering on the difference.
相異點為設有保險絲夾28之連接部28d之側的保險絲接觸部28b之形狀。該保險絲接觸部28b係於比進行導電接觸之接觸點更前端部側以比保險絲端子15a之直徑更大的彎曲率朝內側彎曲，且使連接部28d相對於固定部28a朝斜上方傾斜(例如45度左右)而形成。The difference point is the shape of the fuse contact portion 28b on the side where the connection portion 28d of the fuse clip 28 is provided. The fuse contact portion 28b is bent inward at a bending end ratio larger than the diameter of the fuse terminal 15a at the tip end side of the contact point where the conductive contact is made, and the connecting portion 28d is inclined obliquely upward with respect to the fixing portion 28a (for example, Formed around 45 degrees).
保險絲按壓件29係以與第3圖之情形幾乎相同之形狀配合保險絲夾28而決定中央部之彎曲和端部之接合部的傾斜。The fuse pressing member 29 is fitted with the fuse clip 28 in almost the same shape as in the case of Fig. 3 to determine the inclination of the central portion and the inclination of the joint portion of the end portion.
對於形成為如第4圖所示的保險絲保持件之作用進行說明。可知該保險絲保持件之保險絲夾28之開口側的端面間尺寸D相比第3圖時係較為縮小。上述D尺寸係將保險絲按壓件29固定於保險絲夾28所需的尺寸。當將電力保險絲15併列3相份而配置時，由於彼此必須確保預定之絕緣距離，故最小相間距離為(D尺寸+絕緣距離)。從而，若可縮小D尺寸，則可縮短相間距離。The action of the fuse holder formed as shown in Fig. 4 will be described. It can be seen that the dimension D between the end faces on the opening side of the fuse holder 28 of the fuse holder is smaller than that in the third drawing. The above D dimension is a size required to fix the fuse holder 29 to the fuse clip 28. When the power fuses 15 are arranged side by side in three phases, since the predetermined insulation distance must be secured to each other, the minimum phase-to-phase distance is (D size + insulation distance). Therefore, if the D size can be reduced, the phase distance can be shortened.
當電力保險絲15之直徑較大時，通常尺寸縮小之效果也會較大，故可謀求開閉器之小型化。When the diameter of the electric fuse 15 is large, the effect of downsizing is generally large, so that the size of the shutter can be reduced.
但是，由於第3圖之形狀的方式較易於製作，故電力保險絲15之直徑較小時係使用第3圖之形狀的保險絲保持件，若直徑變大則使用第4圖之形狀的保險絲保持件，分開使用即可。However, since the shape of the shape of Fig. 3 is relatively easy to manufacture, the fuse holder of the shape of Fig. 3 is used when the diameter of the electric fuse 15 is small, and the fuse holder of the shape of Fig. 4 is used if the diameter is increased. , can be used separately.
又，於第1圖及第2圖所說明的真空開閉器僅作為例示，而非限定於圖之構成。本發明為於保險絲安裝構造具有特徵者，只要為附有電力保險絲的真空開閉器即可全面適用。Further, the vacuum shutters described in FIGS. 1 and 2 are merely illustrative and are not limited to the configuration of the drawings. The present invention is characterized by a fuse mounting structure, and can be fully applied as long as it is a vacuum shutter with a power fuse.
如以上所述，依據本實施形態之真空開閉器的保險絲安裝構造，保持電力保險絲之兩端部而加以固定的保險絲保持件係具有保險絲夾，而該保險絲夾係具有固定於電路側的固定部、和從該固定部之兩端扇形擴展地上升而呈V字狀傾斜且相對向的保險絲接觸部，電力保險絲由於係設成至少在抵接於保險絲接觸部的2處進行導電接觸，故在電力保險絲與保險絲夾部間之連接部中，由於至少可以使其於預先想定的2處確實接觸，故接觸電阻之變異少，而可獲得穩定之導電接觸，且提供高可靠性的真空開閉器。As described above, according to the fuse mounting structure of the vacuum switch of the present embodiment, the fuse holder that holds the both ends of the power fuse and is fixed has a fuse clip, and the fuse clip has a fixing portion fixed to the circuit side. And a fuse contact portion that is fan-shaped and inclined from the both ends of the fixed portion and that is inclined in a V shape, and the power fuse is electrically contacted at least at two places that abut against the fuse contact portion. In the connection portion between the power fuse and the fuse clip portion, since at least two places can be surely contacted at predetermined places, the variation of the contact resistance is small, and stable conductive contact can be obtained, and a high reliability vacuum switch can be provided. .
此外，由於在保險絲夾之保險絲接觸部的一側前端部設有扣止爪，於另一側前端部設有連接部，且具有：一端部係與保險絲夾之扣止爪扣合，另一端部則扣留於連接部而將保險絲夾之兩端部繫合，且以將插入保險絲夾的電力保險絲朝保險絲接觸部按壓的方式加以按壓的保險絲按壓件，故可將電力保險絲保持接觸壓地確實按壓至保險絲接觸部。Further, since the front end portion of the fuse contact portion of the fuse holder is provided with a locking claw, the other end portion is provided with a connecting portion, and the one end portion is fastened to the fastening claw of the fuse clip, and the other end is The fuse is pressed against the connecting portion to couple the both ends of the fuse clip, and the power fuse that inserts the fuse clip is pressed against the fuse contact portion, so that the power fuse can be kept in contact with the ground. Press to the fuse contact.
另外，由於設有保險絲夾之連接部之側的保險絲接觸部係於比進行通電接觸的接觸點更前端部側處向內部彎曲，且連接部係形成為相對於固定部朝斜上方傾斜，故加上前述效果可縮小相關尺寸而可使開閉器小型化。Further, since the fuse contact portion on the side where the connection portion of the fuse clip is provided is bent toward the inside from the contact point closer to the energization contact, and the connection portion is formed to be inclined obliquely upward with respect to the fixed portion, In addition to the aforementioned effects, the size can be reduced to make the shutter compact.
