Definitions
- Disconnector with a main switch pin and an auxiliary contact pin
- the invention relates to a disconnector with an axially drivable main switching pin and a counter contact opposite this with a counter contact piece and an axially movable, spring-loaded auxiliary contact pin that contacts the main switching pin in time before the counter contact piece.
- Such a circuit breaker is known for example from DE-OS-39 38 711.
- a main switching pin moves into a mating contact during the switching-on process and makes contact there first with an auxiliary contact pin and then with a mating contact piece in the form of a sliding contact.
- Such an arrangement is chosen in order to be able to control capacitive currents with a disconnector.
- the auxiliary contact pin forms a pre-contact to which an arc can be drawn without the
- the invention is therefore based on the object of designing a disconnector of the type mentioned in such a way that commutation of the current onto the main current path takes place without damage to the rated current contacts even when the high currents occurring when the busbar is changed with low driving voltages.
- auxiliary sliding contact which is conductively connected to the counter contact piece and contacts the auxiliary contact pin in the switched-off position and at the beginning of the switch-on movement of the main contact pin, from which the auxiliary contact pin runs off after the main contact pin has come into contact with the counter contact piece.
- the auxiliary sliding contact ensures a reliable conductive connection between the auxiliary contact pin and the mating contact piece that is also capable of withstanding high currents.
- An advantageous embodiment of the invention provides that the main switching pin and the auxiliary contact pin each consist at least partially of erosion-resistant material on the contacting end faces. 1 This design of the end faces of the contact pins permanently prevents damage to the pre-contact surfaces caused by an electric arc before contact is made.
- FIG. 1 shows the disconnector according to the invention in a section schematically at the start of the switch-on process
- FIG. 2 shows the disconnector from FIG. 1 during the switch-on process
- Figure 3 shows the disconnector in the on state.
- main switching pin 1 has already moved so far to the counter contact 2 that it touches the Q auxiliary contact pin 3 on the end face.
- Main switching pin 1 and auxiliary contact pin 3 are each provided with an erosion-resistant insert 4, 5 in order to avoid damage to their end faces by arcs igniting before contact. 5
- the counter contact 2 is shielded by a field electrode 6. Behind the field electrode 6 is a counter contact piece 7, which carries the rated current.
- the auxiliary contact pin 3 is axially movable through an insulating rod 8 and loaded in the axial direction by a spring 9.
- the spring 9 is insulated from the rest of the construction by an insulating washer 10.
- the auxiliary contact pin 3 is only on 5 contacted the auxiliary sliding contact 11 on its outer surface.
- the auxiliary contact pin 3 is in engagement with the auxiliary sliding contact 11 at least until the contact between the mating contact piece 7 and the main switching pin 1 is established.
- the counter contact piece 7 is arranged so that it slides on the outer surface of the main switching pin 1.
- the auxiliary contact pin 3 has a smaller diameter than the main switching pin 1, so that the auxiliary contact pin 3 does not touch the mating contact piece 7.
