Definitions
- the invention relates to a device for actuating a handle of an electrical switch with electrical contacts and to an electrical switch with such a device.
- Electrical switches in particular electrical circuit breakers, are typically connected by a handle.
- the handle has at least one "OFF" and one "ON” position.
- the handle is operated by a surgeon.
- motor drives are used, which can be placed on the electrical switch and operate the handle.
- motor drives which are mounted on the front side directly above the handle or which are mounted on the side of the electrical switch and actuate the handle with one arm.
- the electrical contacts of a switch are opened or closed. Due to an overcurrent situation, the electrical contacts of a switch may be fused, so that the switch can not be brought into the "OFF" position. With a motor drive, in such a situation there is a risk that the command will cause the electrical switch to be turned “off” to damage the mechanism of the motor drive or the electric switch.
- the invention is therefore based on the object to provide an alternative device that allows a particularly safe handling by an operator of an electrical switch with fused contacts.
- the inventive device for actuating a handle of an electrical switch with electrical contacts comprises an arm for actuating the handle of the electrical switch, which is in operative connection with a mechanical bridge, which can perform a linear movement along a fixed axis, wherein the bridge in two parts formed with a first part and a second part and these two parts are movable along the fixed axis, the first part of the bridge is in operative connection with the arm and the second part is held by a spring on the first part, and wherein the second part the bridge is driven by a mechanism along the fixed axis.
- An advantage of the device according to the invention is that in a blockage of the arm for actuating the handle - for example by fused contacts - is prevented due to the spring-closed connection between the first part and the second part of the bridge that this arm is damaged.
- the spring is formed with a spring constant, which allows a greater force of the counterforce of the electric switch when switching but does not exceed the maximum permissible switching force.
- the first part when switching through the arm driven by the bridge, the first part is separated from the second part against the spring force and the arm is no longer moved in a first direction.
- the spring is designed as a compression spring and energy is stored in the compressed compression spring when the counterforce of the electrical switch when switching through the arm driven by the bridge is exceeded.
- the spring may be formed as a tension spring and energy is stored in the stretched tension spring when the counterforce of the electric switch when switching through the arm driven by the bridge is exceeded.
- the energy stored in the spring moves the arms in a second direction opposite to the first direction. This ensures that, for example, when fused contacts the handle is moved to the "ON" position and thus a surgeon does not read a wrong status of the electrical switch on the handle.
- the movement of the arm in the first direction moves the handle of the electric switch in the direction of the "OFF" position and the movement of the arm in the second direction, the handle of the electrical switch in the direction of the "ON" position.
- the mechanism comprises a driven wheel with a pin, wherein the pin with a highlight on the second part of the bridge cooperates to drive the bridge.
- the object of the invention is also achieved by an electrical switch with a handle for switching the electric current and a device according to the invention, wherein the arm of the device surrounds the handle so that the movement of the arm in the first direction, the handle in the direction of "OFF" Position of the electric switch moves and the movement of the arm in the second direction moves the handle in the direction of the "ON" position.
- FIG. 1 a device 100 for actuating a handle 910 of an electrical switch 900 with electrical contacts 920, 921 is shown.
- the device 100 comprises an arm 130 for actuating the handle 910 of the electrical switch 900.
- FIG. 6 shown in more detail, which is a switch 900 with electrical contacts 920, 921 and a handle 910.
- the electrical switch 900 can be brought into the "ON" position or "OFF" position.
- the handle 910 will be in the "ON" position and would be translated to the left to the "OFF” position.
- the handle 910 is actuated by the device 100 in that the arm 130 encloses the handle 910 and the arm 130 makes a movement to the right or left.
- the arm 130 has an opening 131 into which the handle 910 protrudes.
- the arm 130 is corresponding to the FIG. 6 in operative connection with a mechanical bridge 200 capable of linear motion along a fixed axis 500.
- the bridge 200 is formed in two parts with a first part 210 and a second part 220.
- the first part 210 and the second part 220 are thus also movable along the fixed axis 500.
- the first part 210 of the bridge 200 is in operative connection with the arm 130 FIG. 1 the arm 130 is mechanically rigidly attached to the first part 201 of the bridge 200.
- the first part 210 is connected to the second part 220 of the bridge 200 such that a spring 600 holds the second part 220 on the first part 210.
- the spring 600 according to the FIG. 1 is a compression spring, the second part 210 according to the figure 1 pulls to the right and thus causes the first part 210 and the second part 220 together.
- the apparatus 100 includes a mechanism that drives the second portion 220 of the bridge 200 along the fixed axis 500.
- this mechanism includes a driven wheel 800 with a pin 810, the pin 810 cooperating with a projection 221 on the second part 220 of the bridge 200 to drive the bridge 200.
- the emphasis 221 protrudes according to the FIG. 1 at the lower part of the second part 220 of the bridge 200 out, so that upon rotation of the driven wheel 800 of the pin 810 according to the FIG. 1 the bridge 200 can slide in a first direction 510.
- the spring constant of the spring 600 is designed such that a force greater than the counterforce of the electrical switch 900 is applied when switching by the spring 600. This means that, for example, not fused contacts 920, 921 in the normal and error-free switching operation, the spring constant is selected so that the first part 210 and the second part 220 of the bridge 200 are held together by the spring 600. At higher forces than the counter-force of the electric switch 900 during switching, such as occur in fused electrical contacts 920, 921, the spring constant is designed so that the maximum permissible switching force is not exceeded. That is, when fused contacts 920, 921, the first part 210 separates from the second part 220 of the bridge 200th
- FIG. 2 shows that the first part 210 from the second part 220 of the bridge 200 are separated.
- fused contacts 920, 921 cause the handle 910 can not be completely transferred to the "OFF" position due to the fused contacts 920, 921.
- the second part 210 is further away from the first part 210 of the bridge 200 than in the illustration of FIG. 2 , Additional energy was stored in the spring 600, which was further compressed as a compression spring.
- FIG. 4A also shows the bridge 200 with first part 210 and second part 220, which are separated due to the blocking of the contacts 920, 921, for example, because of merging.
- FIG. 4B 11 shows a view of the arm 130, which can actuate a handle 910 of an electrical switch 900, and also the bridge 200 with a separate first part 210 and a second part 220.
- FIG. 5 As shown, the energy stored in the compression spring 600 has been released and the bridge 200 has been slid in the second direction 520 opposite the first direction 510 along the fixed axis 500.
- the pin 810 no longer cooperates with the highlighting 221 on the second part 220 of the bridge 200, since the pin 810 due to its circular movement of the driven wheel 800 has moved away from the bridge 200 so far that no interaction is possible.
- the energy in the compressed compression spring 600 was so great that the arm 130 returned the handle 910 to its original position. Typically, this is the "on” position, indicating to a surgeon that the device 100 could not translate the electrical switch 900 to the "off” position.
- the position of the handle 910 is in accordance with the status of the contacts 920, 921, which can not be separated due to fusion. An operator knows that thus the electrical switch 900 has a malfunction and can fix this targeted.
- the device 100 may also have a tension spring instead of a compression spring, in which case the energy of the driven arm 130 is stored in the extension of the tension spring.
- the device 100 for actuating a handle 910 of an electrical switch 900 prevents excessive forces from being exerted on the handle 910 by the motor drive, so that the switching mechanism of the electrical switch 900 would be damaged.
- the device 100 ensures that the position of the handle 910 corresponds to the actual physical status of the contacts 920, 921.
- device 100 prevents fused contacts 920, 921 from damaging the motor drive.
- the arm 130 which at a side mounting of the device 100 on the switch 510 have a certain length, thus also has a certain leverage, so that it can be deformed or break.
- the condition according to the FIG. 5 clearly signals to a surgeon that there is a fault in the electrical switch 900.
- this error can be queried by a microswitch, so that it is displayed in a remote control that the electrical switch 900 has a malfunction.

Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Betätigung einer Handhabe eines elektrischen Schalters mit elektrischen Kontakten sowie auf einen elektrischen Schalter mit solch einer Vorrichtung.The invention relates to a device for actuating a handle of an electrical switch with electrical contacts and to an electrical switch with such a device.
Elektrische Schalter, insbesondere elektrische Leistungsschalter, werden typischerweise mit einer Handhabe geschaltet. Die Handhabe hat dabei mindestens eine "AUS"- und eine "EIN"-Stellung. Typischerweise wird die Handhabe von einem Operateur bedient. Zur Fernbedienung einer Handhabe eines solchen elektrischen Schalters werden Motorantriebe verwendet, die auf den elektrischen Schalter aufgesetzt werden können und die Handhabe betätigen können. Es wird unterschieden zwischen Motorantrieben, die an der Frontseite direkt über der Handhabe montiert werden oder die seitlich am elektrischen Schalter angebaut werden und mit einem Arm die Handhabe betätigen.Electrical switches, in particular electrical circuit breakers, are typically connected by a handle. The handle has at least one "OFF" and one "ON" position. Typically, the handle is operated by a surgeon. For remote control of a handle of such an electrical switch motor drives are used, which can be placed on the electrical switch and operate the handle. A distinction is made between motor drives which are mounted on the front side directly above the handle or which are mounted on the side of the electrical switch and actuate the handle with one arm.
Durch die Betätigung der Handhabe werden die elektrischen Kontakte eines Schalters geöffnet oder geschlossen. Aufgrund einer Überstromsituation können die elektrischen Kontakte eines Schalters verschmolzen sein, so dass der Schalter nicht mehr in die "AUS"-Stellung gebracht werden kann. Bei einem Motorantrieb besteht in so einer Situation die Gefahr, dass das Kommando den elektrischen Schalter in "AUS"-Stellung überzuführen dazu führt, dass der Mechanismus des Motorantriebs oder des elektrischen Schalters beschädigt wird.By actuating the handle, the electrical contacts of a switch are opened or closed. Due to an overcurrent situation, the electrical contacts of a switch may be fused, so that the switch can not be brought into the "OFF" position. With a motor drive, in such a situation there is a risk that the command will cause the electrical switch to be turned "off" to damage the mechanism of the motor drive or the electric switch.
Ebenso besteht die Gefahr, dass der Schalter in einer der "AUS"-Stellung benachbarten Stellung verharrt und somit der Operateur den Eindruck hat, dass der elektrische Schalter ausgeschaltet ist und kein Stromfluss mehr möglich ist. Eine sichere Handhabung des elektrischen Schalters für den Operateur ist in so einer Situation nicht möglich.There is also the danger that the switch remains in a position adjacent to the "OFF" position and thus the surgeon has the impression that the electrical switch is switched off and no current flow is possible. A safe handling of the electrical switch for the surgeon is not possible in such a situation.
Der Erfindung liegt daher die Aufgabe zugrunde, eine alternative Vorrichtung anzugeben, die eine besonders sichere Handhabung durch einen Operateur eines elektrischen Schalters ermöglicht bei verschmolzenen Kontakten.The invention is therefore based on the object to provide an alternative device that allows a particularly safe handling by an operator of an electrical switch with fused contacts.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung zur Betätigung einer Handhabe eines elektrischen Schalters mit elektrischen Kontakten gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind in Unteransprüchen angegeben. Die Aufgabe wird ebenfalls durch einen elektrischen Schalter gemäß Anspruch 9 gelöst.This object is achieved by a device for actuating a handle of an electrical switch with electrical contacts according to claim 1. Advantageous embodiments of the device according to the invention are specified in subclaims. The object is also achieved by an electrical switch according to claim 9.
Die erfindungsgemäße Vorrichtung zur Betätigung einer Handhabe eines elektrischen Schalters mit elektrischen Kontakten gemäß Anspruch 1 umfasst einen Arm zur Betätigung der Handhabe des elektrischen Schalters, der in Wirkverbindung mit einer mechanischen Brücke steht, die eine Linearbewegung entlang einer festen Achse ausführen kann, wobei die Brücke zweiteilig mit einem ersten Teil und einem zweiten Teil ausgebildet ist und diese beiden Teile entlang der festen Achse beweglich sind, der erste Teil der Brücke in Wirkverbindung mit dem Arm steht und der zweite Teil von einer Feder am ersten Teil gehalten wird, und wobei der zweite Teil der Brücke mit einem Mechanismus entlang der festen Achse angetrieben wird. Ein Vorteil der erfindungsgemäßen Vorrichtung besteht darin, dass bei einer Blockade des Armes zur Betätigung der Handhabe - beispielsweise durch verschmolzene Kontakte - aufgrund der mit der Feder geschlossenen Verbindung zwischen erstem Teil und zweitem Teil der Brücke verhindert wird, dass dieser Arm beschädigt wird.The inventive device for actuating a handle of an electrical switch with electrical contacts according to claim 1 comprises an arm for actuating the handle of the electrical switch, which is in operative connection with a mechanical bridge, which can perform a linear movement along a fixed axis, wherein the bridge in two parts formed with a first part and a second part and these two parts are movable along the fixed axis, the first part of the bridge is in operative connection with the arm and the second part is held by a spring on the first part, and wherein the second part the bridge is driven by a mechanism along the fixed axis. An advantage of the device according to the invention is that in a blockage of the arm for actuating the handle - for example by fused contacts - is prevented due to the spring-closed connection between the first part and the second part of the bridge that this arm is damaged.
In einer Ausgestaltung der Vorrichtung ist die Feder mit einer Federkonstante ausgebildet, die es erlaubt eine Kraft größer der Gegenkraft des elektrischen Schalters beim Schalten aufzubringen, die aber nicht die maximal zulässige Schaltkraft überschreitet.In one embodiment of the device, the spring is formed with a spring constant, which allows a greater force of the counterforce of the electric switch when switching but does not exceed the maximum permissible switching force.
In einer Ausgestaltung der Vorrichtung wird bei Überschreiten der Gegenkraft des elektrischen Schalters beim Schalten durch den von der Brücke angetriebenen Arm der erste Teil vom zweiten Teil entgegen der Federkraft getrennt und der Arm nicht weiter in eine erste Richtung bewegt. Vorteilhaft hierbei ist, dass eine Beschädigung des Arms bzw. der Vorrichtung oder des elektrischen Schalters verhindert wird.In one embodiment of the device, when the counterforce of the electric switch is exceeded, when switching through the arm driven by the bridge, the first part is separated from the second part against the spring force and the arm is no longer moved in a first direction. The advantage here is that damage to the arm or the device or the electrical switch is prevented.
In einer weiteren Ausgestaltung der Vorrichtung ist die Feder als Druckfeder ausgebildet und bei Überschreiten der Gegenkraft des elektrischen Schalters beim Schalten durch den von der Brücke angetriebenen Arm wird Energie in der zusammengedrückten Druckfeder gespeichert. Alternativ kann die Feder als Zugfeder ausgebildet sein und bei Überschreiten der Gegenkraft des elektrischen Schalters beim Schalten durch den von der Brücke angetriebenen Arm wird Energie in der gedehnten Zugfeder gespeichert.In a further embodiment of the device, the spring is designed as a compression spring and energy is stored in the compressed compression spring when the counterforce of the electrical switch when switching through the arm driven by the bridge is exceeded. Alternatively, the spring may be formed as a tension spring and energy is stored in the stretched tension spring when the counterforce of the electric switch when switching through the arm driven by the bridge is exceeded.
In einer Ausgestaltung der Vorrichtung bewegt die in der Feder gespeicherten Energie den Armen in eine zweite Richtung entgegengesetzt zur ersten Richtung. Dadurch wird sichergestellt, dass beispielsweise bei verschmolzenen Kontakten die Handhabe in die "EIN"-Stellung bewegt wird und somit ein Operateur nicht einen falschen Status des elektrischen Schalters an der Handhabe abliest.In one embodiment of the device, the energy stored in the spring moves the arms in a second direction opposite to the first direction. This ensures that, for example, when fused contacts the handle is moved to the "ON" position and thus a surgeon does not read a wrong status of the electrical switch on the handle.
In einer weiteren Ausgestaltung der Vorrichtung bewegt die Bewegung des Armes in erster Richtung die Handhabe des elektrischen Schalters in Richtung der "AUS"-Stellung und die Bewegung des Armes in zweiter Richtung die Handhabe des elektrischen Schalters in Richtung der "EIN"-Stellung.In a further embodiment of the device, the movement of the arm in the first direction moves the handle of the electric switch in the direction of the "OFF" position and the movement of the arm in the second direction, the handle of the electrical switch in the direction of the "ON" position.
In einer Ausgestaltung der Vorrichtung umfasst der Mechanismus ein angetriebenes Rad mit einem Zapfen, wobei der Zapfen mit einer Hervorhebung am zweiten Teil der Brücke zusammenwirkt zum Antrieb der Brücke.In one embodiment of the device, the mechanism comprises a driven wheel with a pin, wherein the pin with a highlight on the second part of the bridge cooperates to drive the bridge.
Die erfindungsgemäße Aufgabe wird ebenfalls durch einen elektrischen Schalter mit einer Handhabe zum Schalten des elektrischen Stromes und einer erfindungsgemäßen Vorrichtung gelöst, wobei der Arm der Vorrichtung die Handhabe so umschließt, dass die Bewegung des Armes in erster Richtung die Handhabe in Richtung der "AUS"-Stellung des elektrischen Schalters bewegt und die Bewegung des Armes in zweiter Richtung die Handhabe in Richtung der "EIN"-Stellung bewegt.The object of the invention is also achieved by an electrical switch with a handle for switching the electric current and a device according to the invention, wherein the arm of the device surrounds the handle so that the movement of the arm in the first direction, the handle in the direction of "OFF" Position of the electric switch moves and the movement of the arm in the second direction moves the handle in the direction of the "ON" position.
