Definitions
- the invention is directed to a vacuum switch, in particular vacuum circuit breaker, for medium and high voltage with a movable switching unit disposed within a vacuum switching chamber, which movably comprises a contact tappet, an insulator and a driving or switching rod inserted into the vacuum interrupter chamber through a metal bellows, and a fixed contact inserted into the housing of the vacuum interrupter chamber, wherein the upper end of the insulator is fixedly connected to the contact plunger and the lower end of the insulator to the drive or shift rod, and wherein the contact plunger has a conductive connection to a conductor which is in current-conducting Connection with at least one laterally arranged outgoing contact is.
- Circuit-breakers offer the possibility of dissolving existing electrical connections, whereby electrical currents of up to 160 kA can be switched. These currents occur, for example, when there is a short circuit or a ground fault in high voltage networks. Circuit-breakers can not only switch normal operating currents and low overload currents, just like switch-disconnectors, but also separate high overload currents and maximum short-circuit currents. As an overcurrent protection device with a very high switching capacity in the range of 80 kA - 160 kA, you can switch operating equipment or system components both undisturbed and for a limited time in a faulty state, eg in the event of a short circuit. Types of circuit breaker are in addition to gas pressure switches and circuit breakers vacuum switch. With vacuum switches, the contacts are under vacuum to avoid an arc.
- a gas-insulated switchgear with vacuum switches is known in which are arranged within a filled with insulating gas vessel of the gas-insulated switchgear designed as a vacuum switch circuit breaker.
- a vacuum switch each comprises a vacuum switching chamber, which is designed as a vacuum space.
- a fixed contact plunger and a movable contact plunger are arranged, which are led out with their respective contact rods from the vacuum space of the vacuum interrupter chamber.
- the contact rod of the movable contact plunger is led out by a bellows from the vacuum space or the vacuum interrupter chamber.
- this plunger communicates with a power supply carrier and an actuator is provided for actuating the selector rod of the movable contact plunger.
- the insulating capacity of such vacuum switch must not only ensure the necessary insulating capacity of the switching and isolating distance, but also ensure that leakage or surface currents in the open state of the separation path does not flow from the upper port of the vacuum interrupter chamber to the lower port, the connected power supply carrier. To ensure this, it is necessary to have corresponding distances between the connections and the arrangement of the vacuum switch within a vessel filled with insulating gas. This leads to large types of vacuum switches and thus equipped switchgear.
- the movable in the longitudinal direction switching contact of the contact plunger is moved at the startup at high speed and then bounces on the switching contact of the fixed contact and repeatedly hits with a frequency corresponding to the drive system and the movable mass.
- This impact causes during the operating times of the vacuum switch on the one hand, mechanical stress, which strain the metal bellows through which the movable contact plunger is led out of the vacuum chamber.
- a disadvantage of this embodiment is that either a further housing must be provided within the vacuum interrupter chamber, in which the conductive connection is arranged protected, resulting in a significantly increased assembly costs, or it is a complex structure of the conductive connection is necessary that must be formed alternately to a conductive layer an adhesion prevention layer.
- the invention has for its object to provide a solution that allows an improved switching and contact surface design.
- the invention provides an improved switching and contact surface design of the switching contacts of a vacuum switch, which improves the durability of the switching and contact surfaces and thus the switching contact pieces having these surfaces. Due to the formation of outer and inner switching and contact surfaces and their relative mobility to each other, it is possible in a moving apart of the switching contact pieces to form a separation path, the inner switching and contact surfaces of Fixed contact and movable contact plunger as long as to keep in conductive connection to each other until the outer switching and contact surfaces of the respective switching contact pieces are far enough away from each other that an emerging and occurring arc can not skip these outer switching and contact surfaces. The arc then forms on further moving apart and the inner switching and contact surfaces only between them. These are designed accordingly high strength and burn-off and abrasion resistant, so that they are sufficiently durable.
- the surfaces of the outer switching and contact surfaces are highly conductive, since they only have to conduct the rated current.

- the conductor 8 comprises a ring 7, which is arranged fixed on the inside of the contact ring 5. Furthermore, the conductor 8 comprises a plunger ring 21, which is arranged with its inner surface, preferably stationary, on the outer circumference of the contact plunger 17. The plunger ring 21 and the ring 7 are connected to each other via a plurality of connecting elements 22.
