Definitions

the invention relates to a vacuum interrupter for a diverter switch a tap changer, in which all contacts of one phase, which are necessary for switching under load, constitute a structural unit.
Voltage regulation of power transformers must be done without load interruption. Typically, this voltage regulation is done by connecting or disconnecting windings of the transformer. During these switching operations, the load current in the transformer must never be interrupted. Otherwise, damage would occur in the transformer and proper supply of the consumers with electrical energy would no longer be guaranteed.
a diverter switch basically consists of two components: the (actual) diverter switch and the selector.
the selector is connected directly to the taps of a transformer fine stage winding and is used for the load-free preselection of the winding tap to which is to be switched to.
the uninterrupted switching of the load current itself is done with the diverter switch.
the diverter switch on mechanical contacts or vacuum interrupters.
the object of the invention is therefore to provide, starting from the last-mentioned prior art, a vacuum interrupter of the type described above, which is able to provide a simple mechanical solution for switching under load, which is not technically difficult and to use consuming to realize synchronization and also does not have the other disadvantages mentioned.
the vacuum interrupter shown in Figure 1 is surrounded by a rotationally symmetrical insulating cylinder 1, which consists of an electrically non-conductive material is manufactured and protects the inside, under vacuum standing mechanism from external influences and maintains the vacuum. Due to the symmetrical design of the vacuum interrupter, the description summarizes the functions of the individual components, which can be found again in the upper and lower parts.
an upper cap 2 formed as a flange is soldered to the insulating cylinder 1, and a lower cap 3 is attached, each having an opening, through each of which an upper plunger 4 and a lower plunger 5 a mechanical, electrical conductive connection between a respective outer switching position A and B and one, located in the interior of the vacuum switching cell, electrically conductive central contact plate 6 produces.
the mechanical guidance of the axially displaceable plungers 4 and 5 is, on the one hand, taken over by the respective upper and lower bellows 7 and 8 attached to the caps 2 and 3 and used for permanent vacuumization and, on the other hand, by the respective flanges, which are also designed as flanges.
the inner diameter of the rotationally symmetrical caps 2 and 3 and the outer diameter of the plunger 4 and 5 are to be dimensioned so that the respective resistance contact plunger 9 and 10 are mounted axially displaceable, contact-locking.
downwardly stepwise enlarged diameter of the plunger 4 and 5 is achieved with the corresponding axial displacement that the respective resistance contact plunger 9 and 10 by the positive engagement of the components of the upper and lower resistance contact plates 11 and 12 solve and contact with each other Move tappets 4 and 5 in the corresponding axial direction. So that this movement in the static state can not take place unintentionally without intentional external force, must be overcome in an axial displacement, the force applied by an upper and lower compression spring 13 and 14 holding force between the caps 2 and 3 and the resistance tappets 9 and 10.
FIG. 2 shows the switch in the starting position, in which the largest part of the load current, due to the lowest line resistance in the system, flows via the upper plunger 4 to the closed permanent main contact A 15 towards the discharge contact 17.
a much smaller part of the Due to the higher line resistances, current selects the path via the upper upper tappet 4, which is conductively connected in a contact-connected manner to the middle contact plate 6.
a negligible proportion of the load current flows via the conductive connection between the upper tappet 4, the upper resistance contact tappet, in this switching position 9, the upper resistance contact plate 11 and the upper contact resistance 18 toward the discharge contact 17.
the lower plunger 5 is so far open in this switching position that due to the positive connection, due to the change in diameter of the lower plunger 5 of the lower resistance contact plunger 10 of the lower resistance contact plate 12 is lifted.
the upper plunger 4 is raised by an axial displacement so far from the middle contact plate 6 that an electrical separation takes place between the middle contact plate 6 and the upper plunger 4, but not between the upper resistance contact plunger 9 and the upper one Resistor contact plate 11.
the electrically conductive connection between the middle contact plate 6 and the upper plunger 4 is released and the current forced to take the path over the upper resistance switch 18 to the AbleitCount 17.
the lower plunger 5 establishes a conductive connection by means of a corresponding displacement with the middle contact plate 6.
the current it is possible for the current to flow not only, as described in FIG. 6, via the lower crossover resistor 19, but also via the resistance-favorable route of the conductive contact between the middle contact plate 6 and the lower tappet 5.
FIG. 9 shows a second embodiment of a vacuum interrupter according to the invention, which is identical to the basic structure of the vacuum interrupter described in FIG. 1 and fulfills the same technical task.
the upper and lower bellows 7 and 8 are mounted in the vacuumized interior of the insulating cylinder housing 1.
the plunger 4 and 5 formed as a component in Figure 1 are in the embodiment of Figure 9 in two parts: namely in the upper and lower push rod 22 and 23 and the upper and lower plunger 4 and 5.
the storage and management of the plunger 4 and 5 take over, in comparison to the resistance contact plates 11 and 12 of Figure 1, rotated by 180 degrees upper and lower bearings 24 and 25.
the contact points of the push rods 22 and 23 and the plunger 4 and 5 are still optional vapor screens 21 and 22 attached.
the attached between the plungers 4 and 5 and the upper and lower bearing 24 and 25 compression springs 13 and 14 provide for a corresponding axial displacement of the push rods 22 and 23 for the solution of the conductive connection between the respective plungers 4 and 5 and the middle contact plate.
