Definitions

  • the present invention relates to electrical switching devices, and more particularly, relates to the development and operation of a load-break switch which includes a vacuum circuit interrupter allowing the safe interruption of the arc resulting when switching nominal load currents.
  • Vacuum interrupters used for electrical switching devices, particularly in the 6 to 35 kV voltage range, are known in the prior art. Vacuum interrupters can be used for circuit-breakers, and for load-break switches and contactors.
  • load switches are at least in the range of the middle voltage level (up to about 52 kV) often operated in a protective gas atmosphere of SF 6 , which quickly extinguishes the gas resulting from the switching arc and thus prevents destruction of the switch.
  • SF 6 sulfur hexafluoride
  • SF 6 gas insulated switches are no longer preferred due to the greenhouse gas effect of SF 6 (approximately 23,900 times that of CO 2 ).
  • SF 6 is involved in the degradation and destruction of the ozone layer.
  • switches incorporating SF 6 gas require sealing and such sealed switches generally attract higher maintenance costs to ensure proper operation through the lifetime of the switch.
  • a further issue is the recent introduction of reporting requirements associated with such switches, requiring that the switching apparatus is checked annually to determine any leakage, which must then be reported. This reporting places a significant burden on the operators of any such switchgear.
  • Vacuum interrupters have been widely employed in the art because they provide fast, low energy arc interruption with long contact life, low mechanical stress and a high degree of operating safety.
  • a vacuum interrupter the contacts are sealed in a vacuum chamber.
  • One of the contacts is a moveable contact having an operating member extending through a vacuum seal in the chamber.
  • a known circuit breaker from EP-A-342 603 comprises two cartridges or vacuum bottles, arranged one above the other, within an elongate support, borne by a fixed insulating console 'a chassis.
  • the aforementioned known circuit breaker is very large and bulky, and requires a large order of energy, almost double that of a single cartridge.
  • the incorporation of such a circuit breaker in a cell poses serious problems plus the risk of overheating which are also double.
  • EP-A-0433 184 a medium voltage electrical circuit breaker having per pole a support for a cartridge which contains a pair of separable arc contacts one of which is movable, and a mechanism of control for opening and closing the contacts.

  • the vacuum interrupters already used in the higher power range can be used.
  • two contact elements are arranged via a metallic bellows or similar device movable in an evacuated space, typically a ceramic tube, which form the electrical contact when moving towards each other. Due to the high vacuum with very low residual pressure, the formation of a switching arc is prevented here, or it breaks down again in the absence of ionizable gas immediately after a natural zero crossing.
