Description
Einrichtung an Ölschaltern zum raschen Unterdrücken des Lichtbogens, bestehend aus Kolbenkörpern, die um die Schaltkontakte angeordnet sind und beim Schalten nach unten bewegt werden Die Erfindung bezieht sich auf eine Einrichtung an Ölschaltern zum raschen Unterdrücken des Lichtbogens.Equipment on oil switches for rapid suppression of the arc, consisting of piston bodies which are arranged around the switching contacts and at Switches are moved downwards. The invention relates to a device on oil switches to quickly suppress the arc.
Es sind bereits Einrichtungen bekannt geworden, um beim Ausschalten eine Ölströmung an den Schaltstücken hervorzurufen und dadurch frisches Öl zwischen die Schaltstücke zu bringen. Zu diesem Zwecke hat man mit der Schaltbrücke eine Platte fest verbunden, die sich gleichzeitig mit der Schaltbrücke bewegt und wie ein Kolben wirkt. Diese Einrichtung hat jedoch nicht die gewünschte Wirkung, außerdem vergrößert sie in unerwünschter Weise den Ausschaltwiderstand und verringert damit die Ausschaltgeschwindigkeit.There are already devices known to switch off cause an oil flow to the contact pieces and thereby fresh oil between to bring the contact pieces. For this purpose you have one with the switching bridge Plate firmly connected, which moves at the same time with the switching bridge and how a piston acts. However, this facility does not have the desired effect, as well it undesirably increases the switch-off resistance and thus reduces it the switch-off speed.
Nach der Erfindung wird ein kräftiges Aufwärtsströmen des Öles an den Schaltstücken dadurch hervorgerufen, daß Kolbenkörper vorgesehen werden, die mit Ausnahme der Trennstellen den gesamten Gefäßquerschnitt einnehmen und unabhängig von der Traverse, spätestens gleichzeitig mit der Auslösebewegung der Schaltertraverse, nach unten bewegt werden. Diese Vorrichtung wirkt nicht hemmend auf die Ausschaltbewegung. Insbesondere wird nach der Erfindung eine mit der Schaltwelle verbundene Verklinkung des unter Kraftwirkung stehenden Kolbens bereits vor Trennung der Kontakte freigegeben.According to the invention, there is a strong upward flow of the oil the contact pieces caused by the fact that piston bodies are provided which With the exception of the separation points, occupy the entire cross-section of the vessel and independently from the traverse, at the latest simultaneously with the triggering movement of the switch traverse, be moved down. This device does not have an inhibiting effect on the switch-off movement. In particular, according to the invention, a latch connected to the shift shaft is provided of the force-acting piston released before the contacts were separated.
In der Abbildung ist ein Ausführungsbeispiel der Erfindung in senkrechtem und waagerechtem Schnitt dargestellt.In the figure is an embodiment of the invention in vertical and horizontal section.
Die Traverse 2o, welche die Kontakte 16, 17 miteinander verbindet, wird in üblicher Weise durch Drehen der Schalterwelle i i mittels des Gestänges 14 nach unten bewegt. Um die Kontakte können Isolierzylinder 18, ig angeordnet sein, die unten und oben offen sind. Um die Kontakte bzw. die Isolierzylinder ist eine als Kolben 15 wirkende Platte angeordnet, die in ihrer Mitte entsprechend ausgeschnitten ist. Die Platte wird in der dargestellten Lage durch eine Verklinkung gehalten, deren eines Glied 13 an der Platte 15 und deren anderes Glied 12 an der Vierkantwelle i i angeordnet ist. In dieser Lage sind die kräftigen Federn 21, 22 stark gespannt.The traverse 2o, which connects the contacts 16, 17 to one another, is in the usual way by turning the switch shaft i i by means of the linkage 14 moved down. Insulating cylinders 18, ig can be arranged around the contacts, which are open at the bottom and at the top. Around the contacts or the insulating cylinder is a arranged as a piston 15 acting plate, which is cut out in its center accordingly is. The plate is held in the position shown by a latch, whose one link 13 on the plate 15 and the other link 12 on the square shaft i i is arranged. In this position, the strong springs 21, 22 are strongly tensioned.
Wenn beim Auftreten eines unzulässigen Stromes die Schalterwelle ii ausgelöst wird, so löst sich zunächst die Verklinkung der Teile 12, 13, und gleichzeitig geht das Gestänge 14 abwärts und öffnet die Kontakte. Nach Lösung der Klinken i2, 13 entspannen sich die Federn 21, 22 und ziehen die Platten 15 mit großer Kraft abwärts. Dabei wird das Öl verdrängt, es sucht sich einen Weg des geringsten Widerstandes, und dieser führt an den Kontakten aufwärts. Durch das an dieser Stelle bzw. durch die Isolierzylinder hindurch frei nach oben strömende Öl wird der Lichtbogen schnell unterdrückt. Die Spannvorrichtung für die Federn 21,:22- ist in der Abbildung nicht dargestellt.If the switch shaft ii is triggered, the latching of the parts 12, 13, and at the same time is released the linkage 14 goes down and opens the contacts. After releasing the pawls i2, 13 relax the springs 21, 22 and pull the plates 15 with great force down. The oil is displaced, it looks for a path of least resistance, and this leads up to the contacts. Through that at this point or through With oil flowing freely upward through the insulating cylinder, the arc becomes fast suppressed. The tensioning device for springs 21,: 22- is not shown in the illustration shown.
Die Einrichtung hat den Vorteil, daß an die Kontaktstellen immer frisches und kühles Öl geführt wird, das gleichzeitig Ölverbrennungsrückstände von den Kontakten wegspült.The facility has the advantage that the contact points are always fresh and cool oil is passed, which at the same time oil combustion residues from the contacts washes away.
