Definitions

  • the invention relates to a high-voltage disconnector according to the features of the preamble of claim 1.
  • the contact system of a circuit breaker is generally designed in such a way that it can only be can be switched on and off without current load. For this reason, no precautions have been taken with disconnectors which increase the switch-on capacity or which enable the switching off of load or short-circuit currents.
  • a certain switch-on and switch-off capacity must also be required for disconnectors. This is e.g. B. the case when the switch is used to switch a longer line on and off.
  • a switching arc can occur during the opening movement of the isolating contacts.
  • a high voltage disconnector with scissors is known.
  • This high-voltage isolating switch is equipped with main contact pieces and a counter contact piece, whereby, in order to eliminate the above-mentioned defects, resilient, insulated pre-contact pieces are provided, which close with additional switch contacts when switched on before the main contact pieces and open after switching off after the main contact pieces.
  • the invention has for its object to provide a contact arrangement for high-voltage disconnectors, in which the switching speed and the stroke at the contact point between the additional switching contacts is increased.
  • the advantage of the invention is that the arc occurring between the additional switching contacts is quickly extinguished and the occurrence of an arc between the main contact pieces and the counter contact piece is prevented with certainty.
  • Fig. 1 denotes the pre-contact pieces which cooperate with the main contact pieces 2.
  • the pre-contact pieces are fastened to the mating contact piece 4 in an insulating holder 3.
  • Switch contacts 5 are arranged on the pre-contact pieces 1 and the counter contacts 5 ′ which cooperate with them are arranged on the counter contact piece 4.
  • the pre-contact pieces 1 first come into contact with the movable main contact pieces 2 on the scissor bars in a known manner.
  • the circuit is only closed in the course of the further switch-on movement, namely when the pre-contact pieces 1 touch the mating contact piece 4 in an electrically conductive manner.
  • This contact takes place first at the switching contacts 5, 5 'before the movable main contacts 2 touch the counter contact 4.
  • the switching contacts 5, 5 ' also take over the function of switching off residual or commutation currents when the disconnector is switched off.
  • the switching contacts can be particularly protected against the erosion caused by the shutdown arc by equipping them with erosion-resistant material.
  • the pre-contact pieces 1 are C-shaped and are mounted in the insulating holders 3. This mounting and the switching contacts 5, 5 'are arranged at the ends of the mating contact piece 4, with an aperture 6, for example made of plastic, being arranged as protection against possible influencing of the surface of the mating contact by the switching arc.
  • the panel 6 prevents the side on hitting the scissor spar, z. B. under the influence of strong short-circuit forces on the switch contact arrangement of the pre-contact pieces.
  • an extinguishing device 9 which consists of so-called hard gas material.
  • This material is arranged in the immediate vicinity of the additional switching contacts 8, so that an intense gas flow is generated when the arc arises, which causes the arc to be extinguished.
  • the hard gas material can be designed in the form of a sleeve, which receives the switching contacts 8 in its interior, the movable contact piece 8 "moving approximately in the axis of the sleeve, while the fixed contact piece 8 'as a resilient contact piece, for example radially into the Sleeve 9.
  • the fixed contact pieces 8 ' are connected to the counter contact piece 4 via a contact carrier 13.
  • a hood 14 which can be made of metal or weather-resistant plastic.
