可動閘門521係安裝成可對於絕緣座21接觸地滑動。如第6圖所示，在各絕緣座21中，係形成有滑動面211a、212a。再者，各可動閘門521係安裝成可滑動於滑動面211a或滑動面212a。各可動閘門521係可朝左右方向滑動於滑動面211a或滑動面212a，且選擇性地移動至封閉位置與開放位置。 The movable gate 521 is installed to be slidable in contact with the insulating seat 21. As shown in FIG. 6, in each insulating seat 21, sliding surfaces 211a and 212a are formed. Furthermore, each movable gate 521 is installed so as to be slidable on the sliding surface 211a or the sliding surface 212a. Each movable gate 521 is slidable on the sliding surface 211a or the sliding surface 212a in the left-right direction, and is selectively moved to the closed position and the open position.

封閉位置係以封閉板部521a、521b、521c封閉固定閘門部51之開口511a、512a或開口511b、512b的位置。此外，開放位置係未以封閉板部521a、521b、521c封閉開口511a、512a或開口511b、512b的位置。 The closed position is a position where the closing plate portions 521a, 521b, 521c close the openings 511a, 512a or the openings 511b, 512b of the fixed gate portion 51. In addition, the open position is a position where the openings 511a, 512a or the openings 511b, 512b are not closed by the closing plate portions 521a, 521b, 521c.

第9圖係顯示實施形態1之閘門驅動單元之一例的外觀立體圖，第10圖係實施形態1之閘門驅動單元的分解立體圖。如第9圖及第10圖所示，閘門驅動單元53係具備：殼體部530；壓縮彈簧533，係一端固定於殼體部530；及桿534，係基端被壓縮彈簧533的另一端彈推。此外，閘門驅動單元53係具備：線圈彈簧535，係保持成 可對於殼體部530旋轉且一端卡止於殼體部530；及連桿536，係被線圈彈簧535的另一端彈推，且卡合於可動閘門521。 Fig. 9 is an external perspective view showing an example of the gate drive unit of the first embodiment, and Fig. 10 is an exploded perspective view of the gate drive unit of the first embodiment. As shown in Figs. 9 and 10, the gate drive unit 53 includes: a housing portion 530; a compression spring 533, one end of which is fixed to the housing portion 530; and a rod 534, the base end of which is compressed by the other end of the spring 533 Bounce. In addition, the gate drive unit 53 is equipped with: a coil spring 535, The housing part 530 is rotatable and one end is locked to the housing part 530; and the connecting rod 536 is bounced by the other end of the coil spring 535 and is engaged with the movable gate 521.

殼體部530係具備單元座531及單元罩蓋532。單元座531係形成有：滑動溝531a，係供桿534滑動；及圓柱狀的軸部531b，係將連桿536支撐成為可旋轉。單元罩蓋532係從上方安裝於單元座531。單元罩蓋532係形成有朝右方或左方突出的複數個凸部532a、532b。壓縮彈簧533、線圈彈簧535、連桿536、及桿534的一部分係配置在由單元座531與單元罩蓋532所形成的空間。 The housing portion 530 includes a unit seat 531 and a unit cover 532. The unit seat 531 is formed with a sliding groove 531a for the rod 534 to slide, and a cylindrical shaft portion 531b for supporting the connecting rod 536 to be rotatable. The unit cover 532 is attached to the unit base 531 from above. The unit cover 532 is formed with a plurality of convex portions 532a and 532b protruding to the right or left. The compression spring 533, the coil spring 535, the connecting rod 536, and a part of the rod 534 are arranged in the space formed by the unit seat 531 and the unit cover 532.

桿534係具有：延伸部534a，係朝前後方向延伸；基端部534b，係與延伸部534a的後端相連，且固定於壓縮彈簧533的另一端；卡合部534c，係從基端部534b沿著壓縮彈簧533朝後方突出，且左右方向與連桿536相對向的面形成為弧狀；及接觸部534d，係與斷路器本體1接觸且被斷路器本體1推壓。第9圖及第10圖所示的狀態中，桿534係在基端部534b被壓縮彈簧533朝前方彈推的狀態下，基端部534b係卡合於殼體部530。當斷路器本體1收納於拉出框3內時，桿534的接觸部534d會抵抗壓縮彈簧533之回推的力而被斷路器本體1推向後方，使得桿534朝後方移動。 The rod 534 has an extension portion 534a, which extends in the front-rear direction; a base end portion 534b, which is connected to the rear end of the extension portion 534a and is fixed to the other end of the compression spring 533; and an engagement portion 534c, which extends from the base end portion 534b protrudes rearward along the compression spring 533, and the surface facing the connecting rod 536 in the left-right direction is formed in an arc shape; and the contact portion 534d is in contact with the circuit breaker body 1 and is pressed by the circuit breaker body 1. In the state shown in FIGS. 9 and 10, the rod 534 is in a state where the base end 534b is urged forward by the compression spring 533, and the base end 534b is engaged with the housing 530. When the circuit breaker body 1 is housed in the pull-out frame 3, the contact portion 534d of the rod 534 resists the pushing force of the compression spring 533 and is pushed backward by the circuit breaker body 1, causing the rod 534 to move backward.

連桿536係形成為L字形，角部係藉由單元座531的軸部531b可旋轉地支持。連桿536係具有：開口536a，係供軸部531b***；第一臂部536b，係受到線 圈彈簧535的另一端彈推，而將桿534的卡合部534c朝前方彈推；及第二臂部536c，係前端536d從殼體部530的開口530a突出而***至可動閘門521的開口521g。 The connecting rod 536 is formed in an L shape, and the corner is rotatably supported by the shaft portion 531b of the unit base 531. The connecting rod 536 has: an opening 536a for inserting the shaft portion 531b; a first arm portion 536b for receiving the wire The other end of the coil spring 535 bounces to bounce the engaging portion 534c of the rod 534 forward; and the second arm portion 536c, the front end 536d of which protrudes from the opening 530a of the housing portion 530 and is inserted into the opening of the movable gate 521 521g.

當桿534藉由斷路器本體1移動至後方時，第一臂部536b的前端即會被桿534的卡合部534c推向後方。當卡合部534c朝後方移動時，第一臂部536b即會繞著俯視觀察時的順時針方向旋轉。因此，第二臂部536c以軸部531b為旋轉中心而繞著俯視觀察時的順時針方向旋轉，使得第二臂部536c的前端536d從左向右移動。第二臂部536c之前端前端536d係與可動閘門521的開口521g卡合。因此，伴隨著前端536d朝右方的移動，可動閘門521係朝開放位置移動。 When the rod 534 moves to the rear by the circuit breaker body 1, the front end of the first arm portion 536b is pushed back by the engaging portion 534c of the rod 534. When the engaging portion 534c moves to the rear, the first arm portion 536b rotates clockwise in a plan view. Therefore, the second arm portion 536c rotates clockwise in a plan view with the shaft portion 531b as the center of rotation, so that the front end 536d of the second arm portion 536c moves from left to right. The front end 536d of the front end of the second arm portion 536c is engaged with the opening 521g of the movable shutter 521. Therefore, as the front end 536d moves to the right, the movable shutter 521 moves to the open position.

閘門驅動單元53不限於第9圖及第10圖所示的構成，亦可具有在可動閘門521位於開放位置的狀態下將桿予以保持的構成。第11圖係顯示實施形態1之閘門驅動單元之另一例的仰視圖。第12圖係第11圖所示之閘門驅動單元之桿的外觀立體圖。第13圖及第14圖係將桿及連桿安裝於第11圖所示之單元座之狀態之閘門驅動單元的俯視圖。第15圖係沿著第11圖所示之XV-XV線的剖面圖。 The gate drive unit 53 is not limited to the configuration shown in FIGS. 9 and 10, and may have a configuration that holds the rod in a state where the movable gate 521 is in the open position. Fig. 11 is a bottom view showing another example of the gate drive unit of the first embodiment. Figure 12 is an external perspective view of the lever of the gate drive unit shown in Figure 11. Figures 13 and 14 are top views of the gate drive unit in the state where the rod and the connecting rod are installed on the unit seat shown in Figure 11. Fig. 15 is a cross-sectional view taken along the line XV-XV shown in Fig. 11.

第11圖所示的閘門驅動單元53，其單元座531之一部分的形狀、及桿534之形狀的一部分與第9圖的閘門驅動單元53不同。如第12圖所示，桿534係具有從基端部534b的下部朝下方突出的突起部534e。再者， 如第11圖及第13圖所示，單元座531係具有：引導溝531c，係引導設於桿534之突起部534e之前後方向的移動；及凹部531d，係在左方與引導溝531c相連。凹部531d係具有伴隨著桿534往後方的移動而將突起部534e引導至引導溝531c的傾斜部531e。 The gate drive unit 53 shown in FIG. 11 is different from the gate drive unit 53 in FIG. 9 in the shape of a part of the unit seat 531 and a part of the shape of the rod 534. As shown in FIG. 12, the rod 534 has a protrusion 534e protruding downward from the lower part of the base end 534b. Furthermore, As shown in Figures 11 and 13, the unit base 531 has a guide groove 531c that guides the movement of the protrusion 534e provided on the rod 534 in the front and rear directions; and a recess 531d connected to the guide groove 531c on the left . The recessed portion 531d has an inclined portion 531e that guides the protruding portion 534e to the guide groove 531c as the rod 534 moves backward.

斷路器本體1從拉出框3內拉出時，如第13圖所示，桿534的延伸部534a係藉由未圖示之壓縮彈簧533的彈推而朝前方伸出。當從第13圖所示的狀態將斷路器本體1朝向拉出框3移動時，桿534係在以引導溝531c引導突起部534e的情況下朝後方移動，成為第14圖所示的狀態。藉此，可動閘門521係從封閉位置移動至開放位置。 When the circuit breaker body 1 is pulled out from the pull-out frame 3, as shown in FIG. 13, the extension 534a of the rod 534 is pushed forward by the compression spring 533 (not shown). When the circuit breaker body 1 is moved toward the pull-out frame 3 from the state shown in FIG. 13, the rod 534 moves rearward while guiding the protrusion 534e by the guide groove 531c, and becomes the state shown in FIG. 14. Thereby, the movable gate 521 is moved from the closed position to the open position.

此外，在斷路器本體1處於從拉出框3內拉出的狀態下，使桿534朝後方移動，且在突起部534e到達與凹部531d相對向的位置時使桿534旋轉，則突起部534e進入凹部531d。此狀態下，解除朝後方推壓桿534的施力時，突起部534e會卡於凹部531d。由於在突起部534e到達與凹部531d相對向的位置前，可動閘門521係從封閉位置移動至開放位置，因此可將可動閘門521保持在開放位置。 In addition, when the circuit breaker body 1 is pulled out from the pull-out frame 3, the rod 534 is moved backward, and the rod 534 is rotated when the protrusion 534e reaches a position facing the recess 531d, the protrusion 534e Enter the recess 531d. In this state, when the urging force of the rearward pressing rod 534 is released, the protrusion 534e is caught in the recess 531d. Since the movable shutter 521 is moved from the closed position to the open position before the protrusion 534e reaches the position facing the recess 531d, the movable shutter 521 can be held in the open position.

因此，維修檢查時可個別或同時使電源側的可動閘門521與負載側的可動閘門521成為開放位置，藉此，即可個別或同時檢查端子裝置2內之電源側的電路與負載側的電路。另外，桿534的基端部534b係形成為以 延伸部534a為軸中心的圓弧狀。因此，即便使桿534旋轉，桿534的基端部534b與第一臂部536b的距離實質上亦無變化，藉此，可避免桿534對於連桿536施加的力變得過大而使得連桿536壓歪之類的事態。 Therefore, during maintenance and inspection, the movable gate 521 on the power supply side and the movable gate 521 on the load side can be opened separately or simultaneously, so that the power supply side circuit and the load side circuit in the terminal device 2 can be inspected individually or simultaneously. . In addition, the base end 534b of the rod 534 is formed to The extension 534a has an arc shape at the center of the shaft. Therefore, even if the lever 534 is rotated, the distance between the base end portion 534b of the lever 534 and the first arm portion 536b does not change substantially. This prevents the lever 534 from exerting an excessive force on the link 536 and causing the link 536 things like crooked.

此外，在突起部534e卡於凹部531d的狀態下，使斷路器本體1朝向拉出框3移動時，桿534會藉由斷路器本體1而往後方移動。此時，移至凹部531d的突起部534e係在接觸於凹部531d的傾斜部531e滑動而朝後方移動時旋轉，因此在斷路器本體1成為收納於拉出框3之狀態前，旋轉的桿534的姿勢復原而解除突起部534e與凹部531d的卡合。因此，之後再將斷路器本體1從拉出框3拉出時，桿534即藉由壓縮彈簧533而移動。此時，由於突起部534e係已返回引導溝531c的狀態，因而沿著著引導溝531c移動，而突起部534e會移動至比凹部531d更前方。因此，可動閘門521的位置不會維持在開放位置。 In addition, when the circuit breaker body 1 is moved toward the pull-out frame 3 in a state where the protrusion 534e is caught in the recess 531d, the rod 534 moves backward by the circuit breaker body 1. At this time, the protrusion 534e moved to the recess 531d is rotated when the inclined portion 531e contacting the recess 531d slides and moves rearward. Therefore, the lever 534 that rotates before the circuit breaker body 1 is stored in the pull-out frame 3 The posture of the ellipse is restored to release the engagement between the protrusion 534e and the recess 531d. Therefore, when the circuit breaker body 1 is pulled out from the pull-out frame 3 later, the rod 534 is moved by the compression spring 533. At this time, since the protrusion 534e has returned to the state of the guide groove 531c, it moves along the guide groove 531c, and the protrusion 534e moves to the front of the recess 531d. Therefore, the position of the movable gate 521 is not maintained at the open position.

第16圖係實施形態1之斷路器本體收納於拉出框內之狀態之拉出型斷路器的部分剖面圖，第17圖係實施形態1之斷路器本體從拉出框內拉出之狀態之拉出型斷路器的部分剖面圖。另外，第16圖及第17圖中省略了拉出框3及拉出軌道4。 Figure 16 is a partial cross-sectional view of the pull-out type circuit breaker in a state where the circuit breaker body of Embodiment 1 is housed in the pull-out frame, and Figure 17 is a state where the circuit breaker body of Embodiment 1 is drawn out of the pull-out frame Partial cross-sectional view of the pull-out circuit breaker. In addition, the drawing frame 3 and the drawing rail 4 are omitted in FIGS. 16 and 17.

如第16圖所示，在斷路器本體1收納於拉出框3內的狀態下，斷路器側導體11-1係經由第二固定閘門512的開口512a而***於端子裝置2的端子收納部215。端子收納部215中，斷路器側導體11-1係連接於拉 出框側導體22-1的連接器223。同樣地，斷路器側導體11-2係經由第一固定閘門511的開口511a而***於端子裝置2的端子收納部215，且連接於拉出框側導體22-2的連接器223。斷路器側導體11-3係經由第二固定閘門512的開口512a而***於端子裝置2的端子收納部215，且連接於拉出框側導體22-3的連接器223。在斷路器本體1收納於拉出框3內的狀態下，桿534係被推入閘門驅動單元53。 As shown in FIG. 16, in the state where the circuit breaker body 1 is housed in the pull-out frame 3, the circuit breaker side conductor 11-1 is inserted into the terminal receiving portion of the terminal device 2 through the opening 512a of the second fixed gate 512 215. In the terminal receiving portion 215, the circuit breaker side conductor 11-1 is connected to the The connector 223 of the frame-out side conductor 22-1. Similarly, the circuit breaker side conductor 11-2 is inserted into the terminal housing portion 215 of the terminal device 2 through the opening 511a of the first fixed gate 511, and is connected to the connector 223 of the pull-out frame side conductor 22-2. The circuit breaker side conductor 11-3 is inserted into the terminal housing portion 215 of the terminal device 2 through the opening 512a of the second fixed gate 512, and is connected to the connector 223 of the pull-out frame side conductor 22-3. In the state where the circuit breaker body 1 is housed in the pull-out frame 3, the rod 534 is pushed into the gate drive unit 53.

如第17圖所示，拉出型斷路器100係從第16圖所示的狀態將斷路器本體1，從拉出框3內朝前方拉出時，被推入斷路器本體1之單元收納部217的桿534即會藉由第10圖所示的壓縮彈簧55的伸張力而被推向前方。因此，在斷路器側導體11-1、11-2、11-3通過開口511a、512a之後，閘門驅動單元53之第二臂部536c的前端536d會使可動閘門521朝封閉位置移動。藉此，開口511a、512a係藉由封閉板部521a、521b、521c封閉。 As shown in Figure 17, the pull-out type circuit breaker 100 is from the state shown in Figure 16, when the circuit breaker body 1 is pulled out from the drawing frame 3 toward the front, it is pushed into the unit storage of the circuit breaker body 1 The rod 534 of the portion 217 is pushed forward by the tension of the compression spring 55 shown in FIG. 10. Therefore, after the circuit breaker side conductors 11-1, 11-2, 11-3 pass through the openings 511a, 512a, the front end 536d of the second arm portion 536c of the gate drive unit 53 moves the movable gate 521 toward the closed position. Thereby, the openings 511a, 512a are closed by the closing plate portions 521a, 521b, 521c.

接著說明絕緣座21的構成、固定閘門部51的構成、及絕緣座21與固定閘門部51的關係。首先，具體說明絕緣座21的構成。第18圖係顯示實施形態1之絕緣座之一例的前視圖，第19圖係顯示實施形態1之絕緣座之一例的外觀立體圖。 Next, the structure of the insulating seat 21, the structure of the fixed gate portion 51, and the relationship between the insulating seat 21 and the fixed gate portion 51 will be described.

The engaging portions 511k and 512i are arranged adjacent to the notches into which the first extension portions 213f1 and 214f1 of the engaging portions 213f and 214f are inserted. The width of the engaging portion 512i is smaller than the width of the engaging portion 512c. In addition, the width of each of the first fixed gate 511 and the second fixed gate 512 is substantially the same as the width of the insulating seat 21. In addition, the "width" referred to here refers to the distance in the left-right direction.

如第30圖所示，設於端子單元20-2之絕緣座21的卡合部213f、214f與第29圖所示之第一固定閘門511的複數個卡合部511k卡合。此外，設於端子單元20-1之絕緣座21的卡合部213f與第29圖所示之第二固定閘門512的卡合部512i卡合。此外，設於端子單元20-3之絕緣座21的卡合部214f與第29圖所示之第二固定閘門512的複數個卡合部512i卡合。如此，斷路器本體1亦可為未在絕緣座21設置第二突出部213e、214e的構成。另外，斷路器本體1亦可為具有一個端子單元20而進行單相電路之 電路的斷開動作及接通動作的構成。 As shown in FIG. 30, the engaging portions 213f and 214f provided on the insulating seat 21 of the terminal unit 20-2 engage with the plurality of engaging portions 511k of the first fixed gate 511 shown in FIG. 29. In addition, the engaging portion 213f provided on the insulating seat 21 of the terminal unit 20-1 engages with the engaging portion 512i of the second fixed gate 512 shown in FIG. 29. In addition, the engaging portion 214f provided in the insulating seat 21 of the terminal unit 20-3 is engaged with the plurality of engaging portions 512i of the second fixed gate 512 shown in FIG. 29.

The terminal device 2 has a plurality of terminal units 20 and is arranged in the pull-out frame 3. Each terminal unit 20 includes a plurality of pull-out frame-side conductors 22 and 23 connected to the power-side conductor and the load-side conductor, and the supply An insulating seat 21 into which the conductors 22 and 23 on the side of the pull-out frame are inserted. The circuit breaker body 1 has a plurality of circuit breaker side conductors 11, 12 connected to the plurality of draw frame side conductors 22, 23 in a state of being housed in the draw frame 3, and the circuit breaker body 1 can be removed from the draw frame 3 pull out. The gate device 5 includes a first fixed gate 511, a second fixed gate 512, and a movable gate 521. The first fixed gate 511 has a plurality of openings 511 a and 511 b into which a plurality of circuit breaker side conductors 11 and 12 are inserted when the circuit breaker body 1 is stored in the pull-out frame 3. The second fixed gate 512 has a plurality of openings 512a, 512b into which a plurality of circuit breaker-side conductors 11, 12 are inserted when the circuit breaker body 1 is stored in the pull-out frame 3. The movable gate 521 closes a plurality of openings 511a, 512a or a plurality of openings 511b, 512b when the circuit breaker body 1 is pulled out from the drawing frame 3. The plurality of insulating seats 21 are arranged in a direction orthogonal to the direction in which the circuit breaker body 1 is pulled out. Each of the plurality of insulating seats 21 includes a pair of wall portions 213 and 214 facing in a direction orthogonal to the drawing direction. Each of the pair of wall portions 213 and 214 includes engagement portions 213f and 214f that engage with at least one of the first fixed gate 511 and the second fixed gate 512. Each of the engaging portions 213f, 214f has: first extension portions 213f1, 214f1 extending in the pull-out direction; and from the front end of the first extension portions 213f1, 214f1 The second extension portions 213f2 and 214f2 extend in a direction orthogonal to the drawing direction. The second extension portion 213f2 of one of the pair of wall portions 213 and 214 and the second extension portion 214f2 of the other side extend in directions separating from each other. The engaging parts 213f and 214f extend in the opposite direction from the direction facing each other. Therefore, the engaging parts 213f and 214f can be easily arranged at positions where there is no opposite position in the front-to-rear direction. The insulating seat 21 is formed integrally by molding.

此外，第一固定閘門511係具有供第一延伸部213f1、214f1***的開口511f、511i。開口511f、511i係第一開口之一例。第二固定閘門512係具備：缺口部512f、512g，係供第一延伸部213f1、214f1之至少一者***；及卡合部512c、512d，係朝下方突出，且與第一固定閘門511之開口511f、511i中***了第一延伸部213f1、214f1之狀態的卡合部213f、214f的第二延伸部213f2、214f2卡合。藉此，第二固定閘門512係以一部分與第一固定閘門511的一部分彼此重疊的狀態，安裝在裝有第一固定閘門511的端子裝置2。因此，第一固定閘門511係配置於端子裝置2與第二固定閘門512之間，防止第一固定閘門511從端子裝置2脫落。卡合部512c、512d係閘門側卡合部的一例。 In addition, the first fixed gate 511 has openings 511f and 511i into which the first extensions 213f1 and 214f1 are inserted. The openings 511f and 511i are an example of the first opening. The second fixed gate 512 is provided with: notches 512f, 512g for inserting at least one of the first extensions 213f1, 214f1; and engaging parts 512c, 512d, which protrude downward and are connected to the first fixed gate 511 The second extension portions 213f2 and 214f2 of the engaging portions 213f and 214f in the state where the first extension portions 213f1 and 214f1 are inserted into the openings 511f and 511i are engaged. Thereby, the second fixed gate 512 is installed in the terminal device 2 equipped with the first fixed gate 511 in a state where a part of the second fixed gate 511 overlaps with a part of the first fixed gate 511. Therefore, the first fixed gate 511 is arranged between the terminal device 2 and the second fixed gate 512 to prevent the first fixed gate 511 from falling off the terminal device 2. The engaging portions 512c and 512d are examples of the engaging portions on the gate side.

此外，一對壁部213、214的各者係具有朝拉出方向延伸的第二突出部213e、214e。第一固定閘門511係具有供第二突出部213e、214e***的開口511e。開口511e係第二開口的一例。第二固定閘門512係在與斷路器 本體1相對向之面的相反面與第二突出部213e、214e抵接。藉此，既可使第二突出部213e、214e與第一固定閘門511卡合，又可在第二固定閘門512緊靠於第二突出部213e、214e之前面的狀態下，保持第二固定閘門512。因此，可將第一固定閘門511及第二固定閘門512以更穩定的狀態安裝於端子裝置2。 In addition, each of the pair of wall portions 213, 214 has second protrusions 213e, 214e extending in the drawing direction. The first fixed gate 511 has an opening 511e into which the second protrusions 213e and 214e are inserted. The opening 511e is an example of the second opening. The second fixed gate 512 is tied to the circuit breaker The opposite surface of the opposed surface of the main body 1 abuts against the second protrusions 213e and 214e. Thereby, the second projections 213e, 214e can be engaged with the first fixed gate 511, and the second fixed gate 512 can be kept abutting on the front surface of the second projections 213e, 214e. Gate 512. Therefore, the first fixed gate 511 and the second fixed gate 512 can be installed in the terminal device 2 in a more stable state.

此外，開口511e中係***複數個絕緣座21中之鄰接的二個絕緣座21之各者的第二突出部213e。藉此，由於可將第一固定閘門511跨越複數個絕緣座21安裝，因此例如可防止複數個絕緣座21間的位置偏移。 In addition, the second protrusion 213e of each of the two adjacent insulating seats 21 among the plurality of insulating seats 21 is inserted into the opening 511e. Thereby, since the first fixed gate 511 can be installed across the plurality of insulating seats 21, for example, the position shift between the plurality of insulating seats 21 can be prevented.

此外，第一固定閘門511與第二固定閘門512係以彼此的一部分重疊的狀態安裝於端子裝置2。藉此，可將第一固定閘門511及第二固定閘門512以更穩定的狀態安裝於端子裝置2。 In addition, the first fixed gate 511 and the second fixed gate 512 are attached to the terminal device 2 in a state where a part of each other overlaps. Thereby, the first fixed gate 511 and the second fixed gate 512 can be installed on the terminal device 2 in a more stable state.

另外，閘門裝置5係具備連動於斷路器本體1從拉出框3的拉出而移動可動閘門521的閘門驅動單元53。閘門驅動單元53係配置在複數個絕緣座21中之一絕緣座21之內部的複數個拉出框側導體22、23間。由於閘門驅動單元53配置在複數個拉出框側導體22、23間，因此可抑制絕緣座21的寬度及拉出型斷路器100的寬度變大。此外，閘門驅動單元53係配置於絕緣座21中之上下方向的中央。因此，即使斷路器本體1扭轉而收納於拉出框3時，相較於在拉出框側導體22的上方與拉出框側導體23的下方分別配置閘門驅動單元53的情形，可使可動閘 門521精確度良好地移動。此外，例如，閘門驅動單元53配置於端子單元20-1、20-3時，閘門驅動單元53將成為左右分開配置，當斷路器本體1左右扭轉而***時，一方的閘門驅動單元53會較快被驅動，而另一方的閘門驅動單元53則會較慢被驅動，較慢被驅動的可動閘門521會有與斷路器側導體11或斷路器側導體12碰撞的可能性。因此，藉由將閘門驅動單元53配置於複數個絕緣座21中之中央的絕緣座21，即使拉出型斷路器100以左右扭轉的狀態收納到拉出框3時，亦可使可動閘門521精確度良好地移動。 In addition, the gate device 5 includes a gate drive unit 53 that moves the movable gate 521 in conjunction with the drawing of the circuit breaker body 1 from the drawing frame 3. The gate drive unit 53 is arranged between the plurality of pull-out frame side conductors 22 and 23 inside one of the plurality of insulating seats 21. Since the gate drive unit 53 is arranged between the plurality of pull-out frame side conductors 22 and 23, the width of the insulating seat 21 and the width of the pull-out type circuit breaker 100 can be suppressed from increasing. In addition, the gate drive unit 53 is arranged in the center of the insulating seat 21 in the up-down direction. Therefore, even when the circuit breaker body 1 is twisted and stored in the pull-out frame 3, compared to the case where the gate drive unit 53 is separately arranged above the pull-out frame side conductor 22 and below the pull-out frame side conductor 23, it can be moved brake The door 521 moves accurately. In addition, for example, when the gate drive unit 53 is arranged in the terminal units 20-1 and 20-3, the gate drive unit 53 will be arranged separately from the left and right. When the circuit breaker body 1 is twisted left and right and inserted, one of the gate drive units 53 will be more The gate drive unit 53 on the other side is driven more quickly, and the movable gate 521 that is driven more slowly may collide with the circuit breaker side conductor 11 or the circuit breaker side conductor 12. Therefore, by arranging the gate drive unit 53 in the insulating seat 21 at the center of the plurality of insulating seats 21, even when the pull-out type circuit breaker 100 is stored in the pull-out frame 3 in a twisted state, the movable gate 521 can be made Move with good precision.

此外，閘門驅動單元53係具有朝拉出方向彈推的桿534、及連桿536。連桿536係伴隨著桿534朝向與拉出方向相反的方向的移動而旋轉，使可動閘門521從封住複數個開口511a、511b、512a、512b的封閉位置，移動至使複數個開口511a、511b、512a、512b露出的開放位置。藉此，閘門驅動單元53即可藉由較小的力使可動閘門521移動。 In addition, the gate drive unit 53 has a rod 534 that is pushed in the pull-out direction and a link 536. The link 536 rotates with the movement of the rod 534 in the direction opposite to the pull-out direction, so that the movable gate 521 is moved from the closed position that seals the plurality of openings 511a, 511b, 512a, 512b to the plurality of openings 511a, Open positions where 511b, 512a, and 512b are exposed. Thereby, the gate driving unit 53 can move the movable gate 521 with a relatively small force.

此外，閘門驅動單元53係具備單元座531，其係將連桿536保持成可旋轉，且伴隨著桿534朝向與拉出方向相反的方向的移動，接受桿534的***。單元座531可在可動閘門521處於開放位置的狀態下保持桿534。藉此，可在維修檢查時，將電源側的電路與負載側的電路個別或同時地將可動閘門521設為開放位置而檢查端子裝置2內。 In addition, the gate driving unit 53 is provided with a unit seat 531 that holds the link 536 so as to be rotatable and accepts the insertion of the rod 534 as the rod 534 moves in a direction opposite to the pulling direction. The unit seat 531 can hold the rod 534 in a state where the movable shutter 521 is in the open position. Thereby, at the time of maintenance and inspection, the inside of the terminal device 2 can be inspected by setting the movable gate 521 to the open position individually or simultaneously at the time of maintenance and inspection.

此外，桿534係具備突起部534e，其係朝 向屬於與拉出方向正交之方向的下方突出。閘門驅動單元53係具有：引導突起部534e的引導溝531c；及在與拉出方向正交的方向與引導溝531c相連，且卡止突起部534e的凹部531d。藉此，可易於將可動閘門521維持於開放位置。 In addition, the rod 534 is provided with a protrusion 534e, which faces It protrudes downward in a direction orthogonal to the pull-out direction. The gate drive unit 53 has a guide groove 531c that guides the protrusion 534e, and a recess 531d that is connected to the guide groove 531c in a direction orthogonal to the pull-out direction and engages the protrusion 534e. Thereby, the movable gate 521 can be easily maintained in the open position.

此外，凹部531d係具有傾斜部531e，其係使突起部534e伴隨著桿534朝向與拉出方向相反的方向的移動而進入至引導溝531c。藉此，可藉由將斷路器本體1收納至拉出框3使突起部534e返回引導溝531c，而可容易地避免可動閘門521的位置維持在開放位置。 In addition, the recessed portion 531d has an inclined portion 531e that causes the protrusion 534e to enter the guide groove 531c along with the movement of the rod 534 in a direction opposite to the pulling-out direction. Thereby, by storing the circuit breaker body 1 in the pull-out frame 3, the protrusion 534e can be returned to the guide groove 531c, and the position of the movable gate 521 can be easily prevented from being maintained at the open position.
