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.
  • 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 switch 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 Vakuumsehaltkarmmer.

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.

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.
