Description
本發明，係有關於開關器之操作裝置，特別是有關於一併具有斷路器和接地裝置之功能並將「開」、「關」、「接地」之三位置的切換藉由1個操作裝置來進行之三位置開關器用操作裝置。 The present invention relates to an operating device for a switch, and particularly relates to a function of a circuit breaker and a grounding device, and switches three positions of "on", "off", and "ground" by one operating device. The operating device for the three-position switch.
藉由日內瓦機構來以一個操作裝置而進行附有接地裝置之斷路器的「開」、「關」、「接地」之三位置的切換一事，例如係在專利文獻1中有所記載。 The switching of the three positions of "on", "off", and "ground" of the circuit breaker with the grounding device by one of the operating devices by the Geneva mechanism is described, for example, in Patent Document 1.
圖7以及圖8，係為對於使用有日內瓦機構之先前技術的操作裝置之其中一例作展示的概略圖，日內瓦齒輪8之輸出軸9，係經由連桿機構等之操作機構9a而被與可動接觸子10作連結，可動接觸子10，係藉由日內瓦齒輪8之輸出軸9的旋轉，而經由操作機構9a來作旋轉，並與斷路器之固定接觸子11或者是接地裝置之固定接觸子12作相接分離。 7 and 8 are schematic views showing an example of an operation device using a prior art of a Geneva mechanism, and an output shaft 9 of the Geneva gear 8 is movable and movable via an operating mechanism 9a such as a link mechanism. The contact 10 is connected, and the movable contact 10 is rotated by the operating mechanism 9a by the rotation of the output shaft 9 of the Geneva gear 8, and is fixed contact with the fixed contact 11 of the circuit breaker or the grounding device. 12 for separation.
在驅動齒輪4之側面，係被設置有驅動用滾輪6a和圓弧凸部7a，在日內瓦齒輪8處，係被形成有與驅動齒輪4之圓弧凸部7a作卡合並保持「開」、「關」、「接地」位置之圓弧凹部8a、8b、8c，並且係更進而被形成有藉由驅動齒輪4之旋轉而使驅動齒輪4之驅動用滾輪6a作進出之驅動用滾輪卡合溝8d、8e，藉由驅動齒輪4之旋轉， 驅動用滾輪6a係卡合於驅動用滾輪卡合溝8d、8e中，並使日內瓦齒輪8旋轉。 On the side of the drive gear 4, a drive roller 6a and an arcuate projection 7a are provided, and at the Geneva gear 8, a circular convex portion 7a of the drive gear 4 is formed to be engaged and held "on". The arcuate recesses 8a, 8b, and 8c at the "off" and "grounding" positions are further formed with drive roller engagement for driving the drive roller 4a of the drive gear 4 by the rotation of the drive gear 4 The grooves 8d, 8e are rotated by the drive gear 4, The drive roller 6a is engaged with the drive roller engagement grooves 8d and 8e, and the Geneva gear 8 is rotated.
在圖7之「關」位置處，被設置於驅動齒輪4處之圓弧凸部7a，由於係與日內瓦齒輪8之圓弧凹部8c相卡合，因此，輸出軸9係被保持於「關」位置處，輸入軸5係身為能夠空轉的狀態，而由於被設置在驅動齒輪4處之驅動用滾輪6a係並未與日內瓦齒輪8之驅動用滾輪卡合溝8d相卡合，因此驅動齒輪4之輸入軸5的旋轉力係並不會被傳導至日內瓦齒輪8之輸出軸9處。 At the "OFF" position of Fig. 7, the arcuate projection 7a provided at the drive gear 4 is engaged with the arcuate recess 8c of the Geneva gear 8, so that the output shaft 9 is held at "OFF". At the position, the input shaft 5 is idling, and since the drive roller 6a provided at the drive gear 4 is not engaged with the drive roller engagement groove 8d of the Geneva gear 8, the drive is driven. The rotational force of the input shaft 5 of the gear 4 is not transmitted to the output shaft 9 of the Geneva gear 8.
在圖7以及圖8中，若是從「關」位置的狀態起而藉由馬達或手動把手來使被固定在操作軸2處之減速齒輪3朝向順時針方向旋轉，則與減速齒輪3相咬合之驅動齒輪4係朝向逆時針方向旋轉。藉由此旋轉，驅動用滾輪6a係公轉並卡合於日內瓦齒輪8之驅動用滾輪卡合溝8d處而使輸出軸9朝向順時針方向旋轉，並且，驅動齒輪4之圓弧凸部7a和日內瓦齒輪8之圓弧凹部8c之卡合係被解除。如此這般，藉由使日內瓦齒輪8旋轉，日內瓦齒輪8之圓弧凹部8a以及8b亦係旋轉，但是，由於圓弧凹部8a以及8b係從「關」位置保持用之圓弧凹部8c起而被設置於與輸出軸9之動作角度相同之角度θ處，並且驅動用滾輪卡合溝8d、8e係被設置於輸出軸9之動作角度的1/2之角度θ/2處，因此，如圖8中所示一般，「開」動作係結束，圓弧凸部7a和圓弧凹部8a係相卡合，輸出軸9係被保持於「開」位置處。 In FIG. 7 and FIG. 8 , when the reduction gear 3 fixed to the operation shaft 2 is rotated clockwise by a motor or a manual handle from the state of the "off" position, the reduction gear 3 is engaged with the reduction gear 3 The drive gear 4 rotates in a counterclockwise direction. By this rotation, the driving roller 6a revolves and engages with the driving roller engagement groove 8d of the Geneva gear 8 to rotate the output shaft 9 in the clockwise direction, and the arcuate convex portion 7a of the drive gear 4 and The engagement of the circular arc recess 8c of the Geneva gear 8 is released. In this manner, the arcuate recesses 8a and 8b of the Geneva gear 8 are also rotated by rotating the Geneva gear 8, but the arcuate recesses 8a and 8b are rotated from the arcuate recess 8c for holding the "off" position. It is provided at the same angle θ as the operating angle of the output shaft 9, and the driving roller engagement grooves 8d and 8e are provided at an angle θ/2 of 1/2 of the operating angle of the output shaft 9, and therefore, As shown in Fig. 8, generally, the "open" operation is completed, the arcuate convex portion 7a and the arcuate concave portion 8a are engaged, and the output shaft 9 is held at the "on" position.
在此「開」位置之狀態下，若是輸入軸5繼續朝逆時針方向旋轉，則由於圓弧凸部7a和圓弧凹部8a係相卡合，因此輸出軸9係被保持於「開」位置，但是，驅動齒輪4係繼續空轉，直到驅動用滾輪6a與日內瓦齒輪8相衝突後才停止。 In the state of the "on" position, if the input shaft 5 continues to rotate counterclockwise, the arcuate projection 7a and the arcuate recess 8a are engaged, so that the output shaft 9 is held in the "on" position. However, the drive gear 4 continues to idle until the drive roller 6a collides with the Geneva gear 8 to stop.
斷路器之從「開」狀態而設為「關」的操作，係藉由馬達或手動來使操作軸2朝向逆時針方向旋轉，並使日內瓦齒輪8朝向順時針方向旋轉。在操作接地裝置的情況時，係成為前述斷路器之操作的逆方向之操作。本操作裝置，由於驅動用滾輪係為1個且其之公轉半徑係為一定，因此斷路器和接地裝置之動作角度係為相同。 The operation of the circuit breaker from the "on" state to "off" is to rotate the operating shaft 2 counterclockwise by a motor or manually, and to rotate the Geneva gear 8 in the clockwise direction. In the case of operating the grounding device, it is the operation in the reverse direction of the operation of the aforementioned circuit breaker. In this operating device, since the driving roller is one and the revolution radius thereof is constant, the operating angles of the circuit breaker and the grounding device are the same.
[專利文獻1]日本特開平3-133018號公報 [Patent Document 1] Japanese Patent Laid-Open No. 3-133018
在前述先前技術之操作裝置中，係存在有下述之問題。 In the aforementioned prior art operating device, there are the following problems.
(1)由於驅動齒輪之驅動用滾輪係為1個，因此其之公轉半徑係為一定，故而，係必須將斷路器和接地裝置之動作角度設為相同，因此，當斷路器之動作角度和接地裝置之動作角度為相異的情況時，若是驅動用滾輪為1個的操作裝置，則係並無法藉由1台的操作裝置來進行操 作。 (1) Since the driving gear is driven by one roller, the revolution radius is constant. Therefore, the operating angles of the circuit breaker and the grounding device must be the same. Therefore, when the operating angle of the circuit breaker is When the operating angle of the grounding device is different, if the driving roller is one operating device, the operating device cannot be operated by one operating device. Work.
(2)當藉由電動來對於斷路器進行「關」操作的情況時，只要在動作結束後而使馬達停止，則就算是發生有惰轉，該惰轉亦為小到不會造成問題的程度，或者是，若是發生會造成問題的程度之惰轉，則只要施加煞車便可防止其一直超限到接地裝置之操作區域。然而，當藉由手動來進行「關」操作的情況時，雖然存在有開閉顯示，但是由於係並不存在有對於把手停止之擋止器，因此，係會有導致雖然應在「關」處停止但是卻錯誤地一直超限(overrun)至接地裝置之操作區域處之虞，故而會有無法進行確實的操作之隱憂。 (2) When the "off" operation is performed on the circuit breaker by electric power, if the motor is stopped after the end of the operation, even if the idling occurs, the idling is small enough to cause no problem. To the extent, or if the degree of turbulence that causes the problem occurs, the brake can be prevented from exceeding the operating area of the grounding device. However, when the "off" operation is performed manually, there is an open/close display, but since there is no stopper for stopping the handle, there is a tendency to be "off". Stopping, but erroneously overruning to the operating area of the grounding device, there is a concern that the actual operation cannot be performed.
(3)在由日內瓦機構所進行之操作中，一開始，相對於輸入側之動作角度，輸出側之動作角度的比例係幾何級數性地增大，而與此成反比地，相對於輸入轉矩之輸出轉矩的比例係變小。在操作的結束時，則係成為與上述相反，輸出轉矩特性，係成為U字狀。因此，當藉由手動來進行「開」或「接地」操作的情況時，由於僅憑設置在輸出軸處之顯示和操作的手感，係難以掌握動作結束的結束點，因此，會有一直進行操作直到驅動用滾輪和日內瓦齒輪相衝突並停止為止的情況。此時，由於從動作結束起直到與日內瓦齒輪衝突為止的驅動用滾輪之動作角度係為大，因此係變得必須進行不必要的操作，並且，由於開關顯示之位置顯示和操作停止之間的操作之偏差係變大，因此操作性並不佳。 (3) In the operation performed by the Geneva organization, at the beginning, the ratio of the action angle of the output side is geometrically increased relative to the action angle of the input side, and inversely proportional to the input The ratio of the torque output torque is reduced. At the end of the operation, the output torque characteristics are opposite to the above, and the output torque characteristics are U-shaped. Therefore, when the "on" or "ground" operation is performed manually, it is difficult to grasp the end point of the end of the operation due to the display and the feeling of the operation provided at the output shaft, and therefore, there is always going to be performed. The operation is continued until the drive roller and the Geneva gear collide and stop. At this time, since the operating angle of the driving roller from the end of the operation until the collision with the Geneva gear is large, it becomes necessary to perform an unnecessary operation, and since the position display of the switch display and the operation stop are The deviation of the operation becomes large, so the operability is not good.
因此，本發明，係提供一種當斷路器和接地裝置之操作角度為相異的情況時亦能夠將「開」、「關」、「接地」之三位置的切換藉由1台操作裝置來確實地進行之三位置開關器用操作裝置。 Therefore, the present invention provides a method of switching between three positions of "on", "off", and "ground" by a single operation device when the operation angles of the circuit breaker and the grounding device are different. The operating device for the three position switch is performed.

在如同SF6氣體密封開關器一般之為了極力小型化而對於收容機器之配置和機器性能有特殊要求的情況時，會有斷路器之操作角度和接地裝置之操作角度相異的情形。相對於此，例如齒輪式操作裝置，係較為容易藉由一台來與相異操作角度之三位置開關器作對應，但是，由於係會因為操作電壓之變動而使操作角度變動，因此，為了確保接觸信賴性和絕緣性能，係有必要設置有多餘之更長的衝程。本發明之日內瓦式操作裝置，係能夠藉由1台來對於相異之操作角度的三位置開關器進行操作，又，就算是操作電壓有所變動，也不會有開閉角度之變動，因此，動作係為確實，且也不需要對多餘之衝程作考慮，故而，係能夠提供一種動作信賴性為高並為小型且低價之三位置開關器。 In the case where the SF 6 gas-sealed switch generally has a special requirement for the configuration of the housing machine and the machine performance in order to miniaturize it, there is a case where the operating angle of the circuit breaker and the operating angle of the grounding device are different. On the other hand, for example, a gear type operation device is relatively easy to correspond to a three-position switch device having a different operation angle by one unit. However, since the operation angle fluctuates due to a change in the operating voltage, To ensure contact reliability and insulation performance, it is necessary to set a longer stroke. The Geneva-type operating device of the present invention is capable of operating a three-position switch for different operating angles by one unit, and even if the operating voltage is changed, there is no change in the opening and closing angle. Since the operation is true and there is no need to consider the extra stroke, it is possible to provide a three-position switch with high operational reliability and small size and low cost.
本發明之操作裝置，在手動操作時，係藉由在「關」位置處設置擋止器，而在斷路器之「開」-「關」之操作 時以及接地裝置之「關」-「接地」之操作時，均能夠取得明確的操作停止位置，因此，係能夠防止在「關」操作時之超限的誤操作。又，係將擋止器之設置位置藉由限制開關而檢測出來，而能夠對於斷路器操作和接地裝置操作作區別。 The operation device of the present invention operates in the "on"-"off" operation of the circuit breaker by setting the stopper at the "off" position during manual operation. At the time of the "off"-"grounding" operation of the grounding device, a clear operation stop position can be obtained. Therefore, it is possible to prevent an erroneous operation exceeding the limit during the "off" operation. Further, the position of the stopper is detected by the limit switch, and the operation of the circuit breaker and the operation of the grounding device can be distinguished.
本發明之操作裝置，藉由配置2個驅動用滾輪，在手動下之「開」操作時或者是「接地」操作時，從動作結束起直到操作停止為止之無謂的操作角度係變少，在開關顯示之位置顯示和操作停止之間的操作之偏差亦變少。 In the operation device of the present invention, when two driving rollers are arranged, when the operation is "on" or "ground" in the manual operation, the unnecessary operation angle from the end of the operation to the stop of the operation is reduced. The deviation between the display of the switch display position and the operation stop is also reduced.
本發明之操作裝置，藉由在手動操作軸處設置閘門機構並與前述擋止器作連動，係成為能夠進行下述之安全對策等：(1)在電動操作時，係無法進行手動操作。(2)在手動操作時，係無法進行電動操作。(3)若是並非為「關」位置，則無法進行前述擋止器之切換。(4)在手動操作時，若是不在「關」處先暫時將把手拔出，則無法進行前述擋止器之切換。 In the operation device of the present invention, by providing a shutter mechanism at the manual operation shaft and interlocking with the stopper, it is possible to perform the following safety measures and the like: (1) Manual operation is not possible during the electric operation. (2) Electric operation is not possible during manual operation. (3) If the position is not "off", the above stopper cannot be switched. (4) In the manual operation, if the handle is temporarily removed without being in the "OFF" position, the above-mentioned stopper cannot be switched.

圖1，係對於三位置中之「關」位置作展示，若是驅動齒輪4朝向箭頭之方向(逆時針方向)而旋轉，則係成為斷路器之「開」操作，圖2，係對於斷路器之「開」位置作展示，從圖1中所示之「關」位置起來藉由驅動齒輪4之旋轉而使驅動用滾輪6a朝向逆時針方向公轉，並與日內瓦齒輪8之驅動用滾輪卡合溝8d相卡合，而使輸出軸9朝向順時針方向旋轉。藉由使日內瓦齒輪8作動作角度α之旋轉，圓弧凸部7b和圓弧凹部8a係相卡合並成為「開」，而停止馬達1並結束操作。 Figure 1 shows the "off" position in the three positions. If the drive gear 4 rotates in the direction of the arrow (counterclockwise), it becomes the "open" operation of the circuit breaker, and Figure 2 shows the circuit breaker. The "open" position is displayed, and the driving roller 6a is revolved counterclockwise by the rotation of the driving gear 4 from the "off" position shown in FIG. 1, and is engaged with the driving roller of the Geneva gear 8. The groove 8d is engaged, and the output shaft 9 is rotated in the clockwise direction. By rotating the Geneva gear 8 at the operating angle α, the arcuate convex portion 7b and the arcuate concave portion 8a are engaged and "opened", and the motor 1 is stopped and the operation is terminated.
另外，在圖2中，雖然圓弧凸部7b和圓弧凹部8a係相卡合，但是，當在手動操作時而使驅動用滾輪6a朝向順時針方向更進而作了公轉的情況時，輸入側係成為能夠進行空轉直到驅動用滾輪6b與日內瓦齒輪8相衝突為止，對於此事，係在圖2中以點線來作了展示。又，若是從圖2之狀態起而使驅動用滾輪6a朝向順時針方向旋 轉，則係回到圖1之狀態並結束斷路器之「關」操作。 In addition, in FIG. 2, although the circular arc convex part 7b and the circular arc concave part 8a are engaged with each other, when the drive roller 6a is revolved in the clockwise direction at the time of a manual operation, it is input. The side system is capable of idling until the driving roller 6b collides with the Geneva gear 8, and this matter is shown by a dotted line in Fig. 2 . Further, if the driving roller 6a is rotated clockwise from the state of Fig. 2 Turning back to the state of Figure 1 and ending the "off" operation of the circuit breaker.
在圖1中所示之狀態中，斷路器係為「關」且接地裝置亦為「關」。在此狀態下，若是進而使驅動用滾輪6b朝向順時針方向公轉，則係成為「接地」操作，日內瓦齒輪8之輸出軸9係朝向逆時針方向而作動作角度β之旋轉，圓弧凸部7b和圓弧凹部8b係卡合，並被保持於「接地」位置，接地操作係結束。另外，當使驅動用滾輪6b朝向順時針方向作了公轉的情況時，驅動用滾輪6a係與日內瓦齒輪8相衝突，操作係停止。 In the state shown in Fig. 1, the circuit breaker is "off" and the grounding device is also "off". In this state, if the driving roller 6b is further rotated in the clockwise direction, the "grounding" operation is performed, and the output shaft 9 of the Geneva gear 8 is rotated counterclockwise to the operating angle β, and the arc convex portion is formed. 7b and the arcuate recess 8b are engaged and held in the "ground" position, and the grounding operation is completed. Further, when the driving roller 6b is revolved in the clockwise direction, the driving roller 6a collides with the Geneva gear 8, and the operation system is stopped.
圖3，係對於擋止器被設置為電動操作，而斷路器被以電動而成為了「關」操作結束之狀態作展示，圖4，係對於擋止器被設定為斷路器手動操作，而斷路器被以手動而成為了「關」操作結束的狀態作展示。 Fig. 3 shows the state in which the stopper is set to be electrically operated, and the circuit breaker is electrically driven to end the "off" operation, and Fig. 4 is for the stopper to be manually operated as the circuit breaker, and The circuit breaker is manually displayed for the state in which the "off" operation is completed.
在圖3以及圖4中，在被固定於操作裝置上之固定板25處，係以輸出軸9為中心地而以圓弧狀來形成有細縫25a，在此細縫25a內，切換棒23係可滑動地被作配置。在圖示之「關」狀態中，為了使切換棒23在細縫25a內而成為可滑動，細縫25a之寬幅，係被形成為較切換棒23之外徑更廣，並設為能夠自由切換為「斷路器手動操作」、「電動操作」、「接地裝置手動操作」之3個模式的任一者。 In FIG. 3 and FIG. 4, a slit 25a is formed in an arc shape centering on the output shaft 9 at a fixing plate 25 fixed to the operating device, and a switching bar is formed in the slit 25a. The 23 series is slidably configured. In the "off" state shown in the figure, in order to make the switching rod 23 slidable in the slit 25a, the width of the slit 25a is formed to be wider than the outer diameter of the switching rod 23, and It is free to switch to any of the three modes of "manual operation of circuit breaker", "electric operation", and "manual operation of grounding device".
切換棒23，係被與具備有擋止銷22之擋止器21一體 性地構成，擋止器21，係能夠以輸出軸9為中心來作旋轉地，而被配置在固定板25和日內瓦齒輪8之間。切換棒23，係能夠藉由在與彈簧24相抗衡地被朝向軸方向作了拉扯的狀態下而在細縫25a內作滑動，來切換為「斷路器手動操作」、「電動操作」、「接地裝置手動操作」之中的必要之模式，之後，使作了拉扯的切換棒23在軸方向上而返回，來藉由彈簧24而作保持並作設置。若是在此狀態下而進行「開」、「關」、「接地」之操作，則擋止器21，由於係藉由彈簧24而被朝向日內瓦齒輪8作推壓，因此，係與日內瓦齒輪8成為一體而動作。 The switching rod 23 is integrated with the stopper 21 provided with the stopper pin 22. The stopper 21 is rotatably centered on the output shaft 9 and disposed between the fixed plate 25 and the Geneva gear 8. The switching rod 23 can be switched to the "circuit breaker manual operation", "electric operation", and "sliding" in the slit 25a while being pulled toward the axial direction against the spring 24. The necessary mode among the manual operation of the grounding device is followed by returning the pulled switching lever 23 in the axial direction to be held by the spring 24. If the operation of "ON", "OFF", and "Ground" is performed in this state, the stopper 21 is pressed toward the Geneva gear 8 by the spring 24, and therefore, the Geneva gear 8 is attached. Act as one.
又，雖然不論是在3個模式中之何者，於「關」位置處，細縫25a之寬幅均係較切換棒23之外徑更廣，但是，在「關」位置以外，由於係將細縫25a之寬幅設為較切換棒23之外徑更狹窄，因此，係無法將切換棒23朝向軸方向作拉扯，故而，係並無法對模式作切換。 Further, although in any of the three modes, the width of the slit 25a is wider than the outer diameter of the switching rod 23 at the "off" position, but outside the "off" position, Since the width of the slit 25a is made narrower than the outer diameter of the switching rod 23, the switching rod 23 cannot be pulled toward the axial direction, and therefore the mode cannot be switched.
另外，在圖3中所示之「電動操作」模式的情況，切換棒23之細徑部23a係位於與固定板25相同之位置，在圖4中所示之「斷路器手動操作」以及「接地位置手動操作」模式的情況時，切換棒23之細徑部23b係位於與固定板25相同之位置。又，細縫25a之展開的角度，由於係在任一者之模式中均設為就算是進行「開」操作或者是「接地」操作也不會使切換棒23之細徑部23a、23b碰觸到細縫25a之端部一般的角度，因此，係能夠無阻礙地進行「開」以及「接地」操作。當圖3中所示之電動操作之 模式的情況時，驅動用滾輪6a以及6b由於係並不會與擋止銷22相作用，因此係能夠藉由電動而進行三位置之操作。 Further, in the case of the "electric operation" mode shown in Fig. 3, the small diameter portion 23a of the switching rod 23 is located at the same position as the fixed plate 25, and the "circuit breaker manual operation" and " In the case of the grounding position manual operation mode, the small diameter portion 23b of the switching rod 23 is located at the same position as the fixed plate 25. Further, since the angle at which the slit 25a is unfolded is set to be either an "on" operation or a "grounding" operation in either mode, the small diameter portions 23a, 23b of the switching rod 23 are not touched. Since the angle to the end of the slit 25a is normal, the "open" and "grounded" operations can be performed without hindrance. When the electric operation shown in Figure 3 In the case of the mode, since the driving rollers 6a and 6b do not interact with the stopper pin 22, the three-position operation can be performed by electric power.
當如圖4中所示一般，在「斷路器手動操作」模式之「關」位置處而藉由切換棒23來將擋止銷22設置在驅動用滾輪卡合溝8e內的情況時，其中一方之驅動用滾輪6a雖然係能夠卡合於同側之其中一方的驅動用滾輪卡合溝8d中，但是另外一方之驅動用滾輪6b，由於係會碰到存在於同側之另外一方的驅動用滾輪卡合溝8e內的擋止銷22，因此係無法作更進一步之旋轉。故而，斷路器，由於係能夠藉由手動來使驅動用滾輪6a卡合於驅動用滾輪卡合溝8d中，因此係能夠進行「開」、「關」操作，又，在進行「關」操作的情況時，驅動用滾輪6b係由於位在驅動用滾輪卡合溝8e內而會碰到擋止銷22而無法作旋轉，因此，係不會有錯誤的超越「關」而一直操作至「接地」的情形。此時，擋止器21係身為被推壓至日內瓦齒輪8側之深處的狀態，切換棒23之細徑部23b係位於固定板25之位置。固定板25之細縫25a的寬幅，在「關」位置處，係較切換棒23更廣，而，在其以外之位置處，雖係較切換棒23之外徑更狹窄，但是，係設為較23a、23b更廣，因此，在「關」位置處，雖然能夠進行擋止器21之切換，但是在其以外之位置處，切換棒之細徑部23d、23b雖然能夠作滑動但是卻無法進行切換。當對於接地裝置作操作的情況時，亦係與斷路器之操作相同。 As shown in FIG. 4, when the stopper pin 22 is placed in the driving roller engagement groove 8e by the switching lever 23 at the "OFF" position of the "circuit breaker manual operation" mode, One of the driving rollers 6a can be engaged with one of the driving roller engagement grooves 8d on the same side, but the other driving roller 6b is driven by the other one on the same side. The stopper pin 22 in the groove 8e is engaged by the roller, so that it is impossible to rotate further. Therefore, since the circuit breaker can manually engage the driving roller 6a in the driving roller engagement groove 8d, the "open" and "off" operations can be performed, and the "off" operation can be performed. In the case of the drive roller 6b, the drive roller 6b is caught in the drive roller engagement groove 8e, and the stopper pin 22 is prevented from rotating. Therefore, the drive roller 6b does not erroneously override "OFF" and continues to operate. Grounding. At this time, the stopper 21 is in a state of being pressed to the depth of the Geneva gear 8 side, and the small diameter portion 23b of the switching rod 23 is located at the position of the fixed plate 25. The width of the slit 25a of the fixing plate 25 is wider than the switching rod 23 at the "off" position, and is narrower than the outer diameter of the switching rod 23 at other positions. Since it is wider than 23a and 23b, the stopper 21 can be switched at the "OFF" position, but the small diameter portions 23d and 23b of the switching rod can slide even at other positions. It is impossible to switch. When operating in the case of a grounded device, it is also the same as the operation of the circuit breaker.
在圖5以及圖6中，於操作裝置之殼體(未圖示)處，係被設置有手動把手***孔2a，在被固定於操作裝置上之固定板25處，係可上下滑動地被設置有滑動器26。在操作裝置之殼體處，係被設置有手動把手***孔2a，滑動器26，係被與對於將手動把手從操作裝置之外部來通過操作裝置內之手動把手***孔2a作開閉之閘門27作連結。手動把手，係在操作裝置內，被與使操作軸2(參考圖1)作旋轉之機構相連結。閘門27，若是藉由未圖示之控制手段而使手動操作條件被滿足，則係旋轉並將手動把手***孔2a開啟，並且使滑動器26成為可下降。 In FIG. 5 and FIG. 6, a manual handle insertion hole 2a is provided in a casing (not shown) of the operation device, and is slidably slidable at a fixing plate 25 fixed to the operation device. A slider 26 is provided. At the housing of the operating device, a manual handle insertion hole 2a is provided, and the slider 26 is connected to the shutter 27 for opening and closing the manual handle insertion hole 2a through the operation device from the outside of the operation device. Make a link. The manual handle, which is attached to the operating device, is coupled to a mechanism that rotates the operating shaft 2 (see Figure 1). When the manual operation condition is satisfied by the control means (not shown), the shutter 27 rotates and opens the manual handle insertion hole 2a, and the slider 26 can be lowered.
在圖5中，由於係被設置為「電動操作」模式，而擋止器21以及擋止銷22係身為被拉扯至前方的狀態，因此滑動器26係碰到擋止器21，而無法將閘門27開啟。擋止器21，係為圓弧狀，不論是在「開」、「關」、「接地」位置處，滑動器均會碰撞到，因此，手動把手***孔2a係被關閉，故而，係無法使手動把手通過手動把手***孔2a，而成為無法進行手動操作之狀態。在此狀態下，對於閘門27之「閘門開」作顯示的限制開關28係並不會動作，又，由於擋止器21係被拉扯至前方，因此，對於「斷路器手動操作」或者是「接地裝置手動操作」作顯示之限制開關29a以及29b也不會動作。 In FIG. 5, since the stopper 21 and the stopper pin 22 are pulled to the front state because the system is set to the "electric operation" mode, the slider 26 hits the stopper 21 and cannot The shutter 27 is opened. The stopper 21 has an arc shape, and the slider collides with the "open", "off", and "ground" positions. Therefore, the manual handle insertion hole 2a is closed, so The manual handle is inserted into the hole 2a through the manual handle, and the manual operation is impossible. In this state, the limit switch 28 for displaying the "gate open" of the shutter 27 does not operate, and since the stopper 21 is pulled to the front, the "circuit breaker manual operation" or " The limit switches 29a and 29b for the manual operation of the grounding device do not operate.
在圖6中，由於擋止器21以及擋止銷22係身為設置 於被推入至深處之「斷路器手動操作」模式的位置處之狀態，因此，滑動器26係並不會碰撞到擋止器21而自由地滑動，而能夠將閘門27設為開啟的狀態，因此，係能夠將手動把手通過手動把手***孔2a來對於操作軸2進行手動操作。在此狀態下，限制開關28係動作並發出訊號，直到將把手拔出為止，「閘門開」之訊號係持續。 In FIG. 6, since the stopper 21 and the stopper pin 22 are configured as a body In the state of being pushed to the position of the "circuit breaker manual operation" mode in the deep place, therefore, the slider 26 does not collide with the stopper 21 and slides freely, and the shutter 27 can be opened. State, therefore, it is possible to manually operate the operating shaft 2 by inserting the manual handle through the manual handle insertion hole 2a. In this state, the limit switch 28 is actuated and sends a signal until the handle is pulled out, and the "gate open" signal continues.
又，擋止器21係使限制開關29a動作並送出斷路器操作之訊號。此訊號，係再從「關」起直到「開」為止之任一位置處而持續送出，直到操作模式被切換為其他模式為止。另外，限制開關29b，在「斷路器手動操作」之模式中，係不論是在何者之位置處均不會動作，而在成為了「接地裝置手動操作」模式的情況時才會動作並送出訊號。如此這般，係將擋止器之設置位置藉由限制開關而檢測出來，而能夠對於斷路器操作和接地裝置操作作區別。 Further, the stopper 21 is a signal for operating the limit switch 29a and sending out the operation of the circuit breaker. This signal is continuously sent from "off" to "on" until the operation mode is switched to another mode. Further, the limit switch 29b does not operate at any position in the "manual operation of the circuit breaker" mode, but operates and sends a signal when it is in the "grounding device manual operation" mode. . In this way, the position of the stopper is detected by the limit switch, and the operation of the circuit breaker and the operation of the grounding device can be distinguished.
進而，在手動把手之***中，由於滑動器26係對於擋止器21之軸方向的移動作阻止，因此，若是不在「關」位置處而一旦將把手拔出，則係無法切換至「電動操作」以及「接地裝置手動操作」處。 Further, in the insertion of the manual handle, since the slider 26 is prevented from moving in the axial direction of the stopper 21, if the handle is not pulled out, the handle cannot be switched to "electric". Operation" and "Manual operation of grounding device".
