Abstract

在一已知的致动装置中，随着一“断开”触发轴的转动，由一固定在其上的枢轴驱动比如一电磁体后而开始了断开过程，从而使开关杆的滚柱滚过“断开”触发轴，当开关杆已转回并且铰接杆系统已移出伸展位置时，发生了断开过程。但是，在开关杆经过时它撞出了“断开”触发轴。为了减少所产生的“断开”触发器(6)的磨损，以及为了只在断开过程中驱动与“断开”触发轴(6)相关的滑触件(11″)，以获得更多次数的开关动作，该开关杆(1)具有一圆形部分(7)，“断开”触发轴(6)在开关杆(1)的任何位置都与其周面(9)可工作地连接。一触发杆(11)可脱开地连接于“断开”触发轴(6)上，以连接一滑触件(11″)或使之脱开。该致动装置也可用于小油量的断路器。

In a known actuator, the disconnection process is initiated by a pivot fixed thereto, such as an electromagnet, as a result of the rotation of an "off" trigger shaft, causing the roller of the switch lever to roll over the "off" trigger shaft. When the switch lever has rotated back and the hinged lever system has moved out of the extended position, the disconnection process occurs. However, the switch lever knocks out the "off" trigger shaft as it passes. In order to reduce the wear of the "off" trigger (6) and to drive the sliding contact (11") associated with the "off" trigger shaft (6) only during the disconnection process to obtain a greater number of switching operations, the switch lever (1) has a circular portion (7), and the "off" trigger shaft (6) is operatively connected to its peripheral surface (9) in any position of the switch lever (1). A trigger lever (11) is detachably connected to the "off" trigger shaft (6) to connect or disconnect a sliding contact (11"). The actuator can also be used for circuit breakers with small oil volumes.

Description

真空断路器的致动装置Actuating devices for vacuum circuit breakers

本发明涉及一种用于真空断路器、特别是具有三极构造的真空断路器的致动装置，其中一凸轮盘连接于一开关轴，该开关轴受到一设计成一拉簧的开关弹簧的作用力，在也安排在开关轴上的一制动件释放后的关闭过程期间，凸轮盘转动约180°，凸轮盘以如下方式可工作地连接于开关杆的滚柱，即，在开关杆绕转轴的转动期间，第一断路器电极的双臂曲柄系统受力而到达伸展位置，为了锁定，此开关杆具有一第二滚柱，它牢固地安装在此开关杆上，开始时移动经过受到回复弹簧作用力的“断开”触发轴的半轴部分，在开关杆的转动方向倒转后，滚柱顶靠着“断开”触发轴的半轴部分。The invention relates to an actuating device for a vacuum circuit breaker, in particular a vacuum circuit breaker with a three-pole configuration, in which a cam disc is connected to a switching shaft which is acted upon by a switching spring designed as a tension spring Force, during the closing process after the release of a brake also arranged on the switch shaft, the cam disc rotates about 180°, the cam disc is operatively connected to the roller of the switch lever in such a way that the switch lever rotates around During the rotation of the shaft, the bell crank system of the first circuit breaker pole is forced to reach the extended position. For locking, the switch lever has a second roller, which is firmly mounted on the switch lever and initially moves through the The half-shaft portion of the "off" trigger shaft that returns the force of the spring against which the roller abuts against the half-shaft portion of the "off" trigger shaft after the direction of rotation of the switch lever is reversed.

在电气开关设备中，也即在高压电路断路器中，需要断路器能毫不含糊地对付闭合过程和断开过程。特别是，其前提是要有一个致动装置，它能正确地保证在由一电磁体或一按钮开始开关过程时的闭合过程和断开过程的顺序。同时，致动装置必须设计成能对付极多次的开关动作。满足这些前提的致动装置有很多种构造。作为一个例子，这里只提到EP0450194A1和EP0521585A1中的那种。In electrical switching devices, that is to say in high-voltage circuit breakers, it is necessary for the circuit breaker to be able to deal with closing and opening processes unambiguously. In particular, this presupposes an actuating device which correctly guarantees the sequence of the closing and opening processes when the switching process is initiated by an electromagnet or a push button. At the same time, the actuating device must be designed to handle an extremely high number of switching operations. There are many configurations of actuators that satisfy these prerequisites. As an example, only the ones in EP0450194A1 and EP0521585A1 are mentioned here.

在大家还知道的用于三极真空断路器的致动装置中，正如在某种程度上可从Holec Company的文件“真空断路器”3994.047/E 3.10.1-1-103-20-TP-GP中可见到的那样，在由电磁体或按钮开始闭合过程后，经由一连接于“接通”触发轴的销子，所述“接通”触发轴开始转动。在此例中，“接通”触发轴设计成其中央为一半轴，并且在这里连接至一制动件，该制动件安装在真空断路器的后壁上并能转动。当此制动件通过此可工作的连接方式释放时，一在开关轴上的第二制动件同时释放，开关轴受到一设计成拉簧的开关弹簧的作用力。但是，这意味着装有偏心部分的开关轴转动。但是，接着，一牢固地安装在开关轴上的凸轮盘也转过约180°，压在开关杆的滚柱上，其结果是，设计成双杆的开关杆绕转轴转动，从而迫使第一断路器电极的双臂曲柄系统到达伸展位置。当此双臂曲柄系统受力而到达伸展位置时，则第二和第三断路器电极的双臂曲柄系统利用切换杆也到达伸展位置，这创造了由一连接件和一开关杆完成闭合过程的先决条件，该连接件适用于每个断路器电极，开关摆杆也同样适用于每个断路器电极，如果情形如此，则开关杆被锁住，而同样牢固地安装在开关杆上的一滚柱移动经过“断开”触发轴的半轴部分，从而使后者顶着回复弹簧的力而转动，一旦此滚柱已经经过，则开关杆转动，滚柱撞击在“断开”触发轴的半轴部分上，锁住了开关过程。Among the actuating devices also known for three-pole vacuum circuit breakers, as to some extent from Holec Company's document "Vacuum Circuit Breakers" 3994.047/E 3.10.1-1-103-20-TP- As can be seen in the GP, after the closing process has been initiated by the electromagnet or push button, the "on" trigger shaft starts to rotate via a pin connected to the "on" trigger shaft. In this example, the "on" trigger shaft is designed with a half shaft in its center and is connected here to a stopper, which is mounted on the rear wall of the vacuum circuit breaker and is rotatable. When the brake part is released through the operative connection, a second brake part on the switch shaft is released at the same time, and the switch shaft is subjected to the active force of a switch spring designed as a tension spring. However, this means that the switch shaft on which the eccentric part is mounted turns. Then, however, a cam disc firmly mounted on the switch shaft is also rotated through about 180° and presses against the rollers of the switch lever. As a result, the switch lever, which is designed as a double lever, turns around the axis of rotation, forcing the first The bell crank system of the breaker pole reaches the extended position. When this bell crank system is stressed to reach the extended position, the bell crank systems of the second and third circuit breaker poles also reach the extended position by means of the switching lever, which creates a closing process completed by a connecting piece and a switching lever prerequisite, the connection piece is suitable for each circuit breaker pole, the switch lever is also suitable for each circuit breaker pole, if this is the case, the switch lever is locked, and a The roller moves past the half-shaft part of the "off" trigger shaft, causing the latter to turn against the force of the return spring, once this roller has passed, the switch lever turns and the roller strikes against the "off" trigger shaft On the semi-shaft part, the switching process is locked.

在这种已知的致动装置中，断开过程也由电磁体或按钮触发。在这种情况下，“断开”触发轴由一安装在其上的销子所转动，直到滚柱能移动经过“断开”触发轴。接着，开关杆可转回，而双臂曲柄系统移动而离开伸展位置。开关摆杆可因此而转动，在设计成压簧的断开弹簧作用下，发生了断开过程，三个断路器电极的每个移动接触件都有压簧，它们在闭合过程中受到压力。In this known actuating device, the disconnection process is also triggered by an electromagnet or a button. In this case, the "off" trigger shaft is rotated by a pin mounted thereon until the roller can move past the "off" trigger shaft. The switch lever can then be rotated back while the bellcrank system moves out of the extended position. The switch rocker can therefore be rotated, and the opening process takes place under the action of the opening spring designed as a compression spring. Each moving contact of the three circuit breaker poles has a compression spring, which is stressed during the closing process.

利用这种用于三极真空断路器的已知致动装置，可毫不含糊地解决真空断路器的闭合过程和断开过程，并实现预定次数的开关动作。With this known actuating device for a three-pole vacuum circuit breaker, the closing and opening processes of the vacuum circuit breaker can be solved unambiguously and a predetermined number of switching operations can be realized.

但是，由于开关杆在移动经过“断开”触发轴时与之撞击，造成“断开”触发轴上的严重磨损。However, severe wear on the "off" trigger shaft was caused due to the switch lever hitting it as it moved past the "off" trigger shaft.

“断开”触发轴的用来在开关过程中发出信号的滑触件在闭合过程和断开过程期间都工作。The slider of the "open" trigger shaft for signaling during the switching process works both during the closing process and during the opening process.

本发明的目的是提供一种用于真空断路器、特别是具有三极构造的真空断路器的致动装置，其中，在一安装在开关轴上并可工作地连接于开关杆的滚柱上的凸轮盘的基础上，为了在进行闭合过程后锁定，为了减少因开关杆经过“断开”触发杆并与之撞击而在其上产生的磨损，以及为了在断开过程期间“断开”触发轴的滑触件才工作，开关轴停靠在“断开”触发轴的半轴部分上，这样，提供了一种可保证具有较大次数的开关动作的真空断路器。The object of the present invention is to provide an actuating device for a vacuum circuit breaker, in particular a vacuum circuit breaker with a three-pole configuration, in which, on a roller mounted on the switch shaft and operatively connected to the switch lever on the basis of a cam disc, for locking after the closing process, to reduce the wear on the switch lever as it passes and hits the "open" trigger lever, and for the "open" during the opening process Only when the sliding contact of the trigger shaft works, the switch shaft rests on the semi-axis portion of the "off" trigger shaft, thus providing a vacuum circuit breaker that can ensure a relatively large number of switching operations.

本发明实现上述目的的方案是，开关杆在其朝着“断开”触发轴的一侧在其转轴上方有一加宽部分，该加宽部分以下面方式设计成一圆形部分，即，在开关杆的每一位置，甚至在锁定位置，“断开”触发轴都可工作地连接于圆形部分的周面，一触发杆安装在“断开”触发轴上，可从“断开”触发轴上脱开以连接滑触件或使之脱开，并且在开始断开过程时，经由一连接于“断开”触发轴的挡止件，使“断开”触发轴与其半轴部分一起转动，以使开关杆脱开锁定。The solution of the present invention to achieve the above object is that the switch lever has a widening above its axis of rotation on its side facing the "off" trigger axis, which widening is designed as a circular part in the following manner, that is, at the switch In each position of the lever, even in the locked position, the "off" trigger shaft is operatively connected to the circumference of the circular part. A trigger lever is mounted on the "off" trigger shaft and can be triggered from the "off" Disengage on the shaft to connect the sliding contact or make it disengage, and when starting the disconnection process, the "break" trigger shaft is connected with its half shaft part through a stop connected to the "break" trigger shaft Turn to disengage the switch lever from locking.

由于在开关杆的每个位置上“断开”触发轴现在都靠在开关杆的圆形部分的周面上，而且无论开关杆在“接通”位置或“断开”位置时，都相当精确，当开关杆经过所述“断开”触发轴时“断开”触发轴都不再被撞击。但是，这意味着“断开”触发轴不再是一个在致动装置中受到磨损的部件，从而在这点上为在致动装置中的开关动作可达40,000次创造了条件。在这种情况下，如果开关杆所具有的第二滚柱位于圆形部分的周面的上部部分，则是有利的，从而在“断开”触发轴的运动开始时在开关杆的圆形部分的周面上所要克服的摩擦阻力很小。Since the "off" trigger shaft now rests on the circumference of the circular part of the switch lever at each position of the switch lever, and no matter whether the switch lever is in the "on" position or the "off" position, the Precisely, the "off" trigger shaft is no longer struck when the switch lever passes said "off" trigger shaft. However, this means that the "off" trigger shaft is no longer a component subject to wear in the actuating device, thereby allowing up to 40,000 switching operations in the actuating device at this point. In this case, it is advantageous if the switching lever has a second roller located in the upper part of the circumference of the circular part, so that at the beginning of the movement of the "off" trigger shaft the circular part of the switching lever The frictional resistance to be overcome on the peripheral surface of the part is very small.

但是，另一方面，由于触发杆使滑触件现在只在断开过程中才工作，“断开”触发轴的滑触件也受到较小的应力，该触发杆安装在“断开”触发轴上并可从其上脱开以连接滑触件或使之脱开，并且与连接至“断开”触发轴的挡止件相互作用。由于这因此避免了滑触件在闭合过程中工作，用来发出信号的滑触件上的应力减小了一半，这样，本发明的致动装置在整体上提高了开关动作的次数，因此也提高了真空断路器的寿命。On the other hand, however, the slider of the "off" trigger shaft is also less stressed due to the fact that the slider is now only active during the break-off process by the trigger lever, which is mounted on the "break-off" trigger On and off the shaft to connect or disengage the slider and interact with a stop connected to the "off" trigger shaft. Since this avoids the work of the sliding contact during the closing process, the stress on the sliding contact for sending out signals is reduced by half, so that the actuating device of the present invention improves the number of switching actions as a whole, and therefore also The life of the vacuum circuit breaker is improved.

在本发明的一种进一步构造中，安装在“断开”触发轴上并可脱开的触发杆安装在“断开”触发轴上的枢轴上而可转动，而“断开”触发轴本身安装在真空断路器的中间壁和后壁上而可转动。在这种情况下，触发杆在其朝着开关杆的转轴的上侧上有一凹部，操纵着触发杆的电磁体或按钮配合在凹部内，也即在触发杆被向下施力时，得到牢靠的引导。同时，触发杆的与凹部相反的一侧连接于安装在触发杆下方有一拉簧，该拉簧最好位于真空断路器的中间壁上，从而，当操纵着触发杆的电磁体或按钮不与触发杆的凹部配合时，保证了触发杆在拉簧作用下又回到其初始位置。In a further development of the invention, the releasable trigger lever mounted on the "off" trigger shaft is rotatably mounted on a pivot on the "off" trigger shaft, and the "off" trigger shaft It is installed on the middle wall and the rear wall of the vacuum circuit breaker to be rotatable. In this case, the triggering lever has a recess on its upper side towards the axis of rotation of the switch lever, in which the electromagnet or button actuating the triggering lever fits, i.e. when the triggering lever is forced downwards, a Solid guidance. At the same time, the opposite side of the trigger lever to the recess is connected to a tension spring installed below the trigger lever. When the concave part of the trigger lever cooperates, it is ensured that the trigger lever returns to its initial position under the action of the tension spring.

当然，任何所希望的部件可用于挡止件，它由“断开”触发轴的半轴部分连接于触发轴，只要它能够在所述“断开”触发轴上的触发杆转动期间利用触发杆上的挡止作用驱动“断开”触发轴，以便利用“断开”触发轴的转动而开始断开过程。但是，已发现用一销子作为挡止件是有益的，该销子连接于“断开”触发轴，沿径向行进。Of course, any desired component may be used for the stop, which is connected to the trigger shaft by the half-shaft portion of the "break" trigger shaft, as long as it is able to utilize the trigger during rotation of the trigger lever on said "break" trigger shaft. The stop action on the lever drives the "break" trigger shaft to initiate the break process with the rotation of the "break" trigger shaft. However, it has been found to be beneficial to use as a stop a pin which is connected to the "off" trigger shaft and travels radially.

最后，同样为了减少在致动装置的部件上产生的磨损，如果连接于开关杆的双臂曲柄系统的轴承是一滚柱轴承，双臂曲柄系统的一个杆由开关杆本身构成，则是有利的。Finally, also in order to reduce the wear occurring on the parts of the actuating device, it is advantageous if the bearing of the bellcrank system connected to the switch lever is a roller bearing, one lever of the bellcrank system being constituted by the switch lever itself of.

本发明将结合一实施例在下文中详细解释。附图中：The present invention will be explained in detail below with reference to an embodiment. In the attached picture:

图1显示了处于“接通”位置的在开关杆区域中的致动装置；Figure 1 shows the actuating means in the area of the switch lever in the "ON" position;

图2显示了处于“断开”位置的在开关杆区域中的致动装置；Figure 2 shows the actuating means in the area of the switch lever in the "off" position;

图3为触发杆的平面图，该触发杆安装在如图1和图2所示的致动装置的“断开”触发轴上。FIG. 3 is a plan view of the trigger lever mounted on the "off" trigger shaft of the actuator shown in FIGS. 1 and 2 .

如图1所示，开关杆1在其中央处可绕一转轴2转动，其上部具有一滚柱3，当发生闭合时，滚柱3与一位于开关轴4上的凸轮盘5相互使用。开关杆1在朝着“断开”触发轴6的一侧上具有一加宽部分，该部分设计成一圆形部分7。As shown in Figure 1, the switch lever 1 can rotate around a rotating shaft 2 at its center, and has a roller 3 on its upper part. When closing, the roller 3 interacts with a cam plate 5 located on the switch shaft 4. On the side facing the “off” triggering axis 6 , the switching lever 1 has a widening, which is designed as a circular portion 7 .

从图2中也可看到，在开关杆1的每一个位置上，“断开”触发轴6的半轴部分8位于圆形部分7的周面9上，这样，在开关杆1经过时，不再会撞击“断开”触发轴6。同时，当开关杆1位于闭合位置时，“断开”触发轴6接触一滚柱10，此滚柱10布置在圆形部分7的周面9的上部部分内，这样，当“断开”触发轴6处于图示的位置时，开关杆1被锁住。It can also be seen from FIG. 2 that in each position of the switch lever 1, the semi-axis part 8 of the "off" trigger shaft 6 is located on the peripheral surface 9 of the circular part 7, so that when the switch lever 1 passes , will no longer hit the "break" trigger axis 6. At the same time, when the switch lever 1 is in the closed position, the "open" trigger shaft 6 contacts a roller 10, which is arranged in the upper part of the peripheral surface 9 of the circular part 7, so that when the "open" When the trigger shaft 6 is in the position shown in the figure, the switch lever 1 is locked.

结合图3可见，一触发杆11安装在“断开”触发轴6上，并且可以从“断开”触发轴6脱离，以连接一滑触件11′或使之脱开。此“断开”触发轴6的脱离动作是通过这样的构造实现的：触发杆11安装在“断开”触发轴6的枢轴12上而可以转动，“断开”触发轴6安装在真空断路器的中间壁13和前壁14上而可以转动。一挡止件15连接至“断开”触发轴6，其形式上为一销子，当为了开始脱开过程而电磁体11″配合在触发杆11的凹部16内时，挡止件15撞击在触发杆11上。其结果是，触发杆11顶着安装在中间壁13上的拉簧17的力而在“断开”触发轴6上转动，从而经由销子形式的挡止件15驱动“断开”触发轴6，使此“断开”触发轴6作相同转动，促使开关杆1解除锁定。锁定的解除放开了开关杆1，使之绕转轴2转动到图2所示的位置。开关杆1和第二杆19一起构成了一双臂曲柄系统20，该第二杆19安装在转轴21上，在那里与一导杆22配合，导杆22本身安装在一转轴23上，开关杆1的下部杆18经由一轴承24连接于一切换杆25，该轴承为一滚柱轴承，该切换杆25连接到相邻断路器电极的双臂曲柄系统20-也由-切换杆实现至第三个断路器电极的这种连接-这保证了当由“断开”触发轴6解除开关杆1的锁定时，真空断路器的所有三个断路器电极实质上同时脱开。As can be seen in conjunction with FIG. 3, a trigger lever 11 is mounted on the "off" trigger shaft 6 and can be disengaged from the "off" trigger shaft 6 to connect or disconnect a slider 11'. The disengagement action of this "break" trigger shaft 6 is realized by such a structure: the trigger lever 11 is installed on the pivot 12 of the "break" trigger shaft 6 and can rotate, and the "break" trigger shaft 6 is installed in a vacuum The intermediate wall 13 and the front wall 14 of the circuit breaker are rotatable. A stop 15 is connected to the "break" trigger shaft 6, in the form of a pin, which strikes when the electromagnet 11" fits in the recess 16 of the trigger lever 11 in order to start the disengagement process. on the trigger lever 11. As a result, the trigger lever 11 turns on the "off" trigger shaft 6 against the force of a tension spring 17 mounted on the intermediate wall 13, thereby driving via a stop 15 in the form of a pin "Disconnect" the trigger shaft 6, make the "disconnect" trigger shaft 6 do the same rotation, impel the switch lever 1 to unlock. The release of the lock releases the switch lever 1, making it rotate around the rotation axis 2 to the position shown in Figure 2 Position. The switch lever 1 and the second lever 19 together form a bell crank system 20, the second lever 19 is mounted on the shaft 21, where it cooperates with a guide rod 22, which itself is mounted on a shaft 23 , the lower rod 18 of the switching rod 1 is connected via a bearing 24 to a switching rod 25, which is a roller bearing, and the switching rod 25 is connected to the bell crank system 20 of the adjacent circuit breaker pole - also by the switching rod This connection to the third breaker pole is achieved - this ensures that when the switch lever 1 is unlocked by the "off" trigger shaft 6, all three breaker poles of the vacuum circuit breaker are disengaged substantially simultaneously.

如果触发杆11在已由电磁体11″驱动后再次被放开，则触发杆11由拉簧17作用而又回到如图2所示的位置。然而，这意味着在随后的闭合过程中，触发器11不动作。在此过程中，随着开关轴4的转动以及在开关轴4上的凸轮盘5的作用下，滚柱3从图2中的位置移动到图1中的位置，也即移动到闭合位置，开关杆1受力。即使“断开”触发轴6现在再次转动，触发杆11也不动作。这保证了滑触件11″在闭合过程中也不动作。If the trigger lever 11 is released again after having been driven by the electromagnet 11 ", the trigger lever 11 is acted upon by the tension spring 17 and returns to the position shown in Fig. 2. However, this means that in the subsequent closing process , the trigger 11 does not act. In this process, with the rotation of the switch shaft 4 and the action of the cam plate 5 on the switch shaft 4, the roller 3 moves from the position in Fig. 2 to the position in Fig. 1, That is to say, when it moves to the closed position, the switch lever 1 is stressed. Even if the "off" trigger shaft 6 now rotates again, the trigger lever 11 does not act. This ensures that the sliding contact 11" does not act during the closing process.
