Definitions

  • the invention relates to a switch pole for circuit breakers, consisting of a vacuum interrupter and an insulating housing accommodating this interrupter.
  • the switching chamber consists essentially of a fixed and a movable contact rod, both of which each carry a contact piece and two isolators, between which a metal screen is arranged.
  • In the insulating housing there are two axially offset and control electrodes partially encompassing the vacuum chamber, which are each articulated to the potential of the closest contact rod.
  • vacuum interrupters in switching devices, which consist of an evacuated housing with a fixed and a movable contact piece and metal screen.
  • the fixed contact piece is attached to a fixed contact rod, which is led out of the housing in a vacuum-tight manner by an insulator.
  • the movable contact piece is attached to an axially movable contact rod, which is led out vacuum-tight by an insulator and a metal bellows.
  • metal shields lying on free potential are attached between the insulators.
  • control electrodes axially offset in the insulating housing for solid-insulated switch poles in order to prevent partial electrical discharges in the area between the switching chamber and the insulating housing or in the insulating housing itself by avoiding extremely high field strengths locally and to keep small distances by shifting the electrical stress into the To achieve solid insulation.
  • These control electrodes are connected to the potential of the closest connection of the vacuum interrupter.
  • a third control electrode is provided in the area of the shield of the switching chamber in the insulating housing. They are arranged in such a way that they assume an intermediate potential between the connection potential and earth potential (EPa 01 76 665).
  • control electrodes can also cover conductive or semiconducting take that are applied to parts of the insulating housing.
  • the field strength distribution is improved and the insulating material is used more uniformly; the insufficient consideration of the potential of the metal shield of the vacuum interrupter chamber still does not lead to an optimal switching capacity and also does not improve its internal insulating capacity in all switching positions.
  • insufficient information has been given on the level of the intermediate potential and its influence on the voltage distribution and on the switching capacity.
  • the different capacitive influencing of the intermediate potential by the electrodes located nearby z. B. the grounded coating on the outer surface of the insulating housing is not optimally taken into account.
  • the invention is therefore based on the object, a switch pole according to the preamble of claim so that in both switching states “on” and “off” the electrical field strength and the associated risk of partial discharges in sections between Insulation housing and vacuum interrupter chamber reduced to a minimum and in connection with this the influence of neighboring electrodes on the voltage distribution in the vacuum interrupter chamber and their breaking capacity can be almost avoided.
  • a switch pole for circuit breakers consisting of a vacuum interrupter and an insulating housing which accommodates this interrupter -
  • the interrupter essentially consists of a fixed and a movable contact rod, each carrying a contact piece, which in one of two insulators, a metal bellows and a metal screen between the isolators existing vacuum interrupter are solved, according to the invention, in that two control electrodes are axially offset in the insulating housing and the vacuum interrupter is at least partially provided comprehensively and is articulated to the potential of the nearest contact rod.
  • the two control electrodes must either overlap or be so close to one another and / or dimensioned that the metal screen of the vacuum interrupter assumes a potential which, in the state of separated contact pieces, corresponds to approximately half the potential of the voltage-carrying contact piece.
  • the metal screen of the vacuum interrupter should assume at least approximately full potential, while the influence of grounded or live parts outside the control electrodes on the potential of the metal screen should be virtually eliminated.
  • a switch pole is shown in which a complete vacuum switching chamber 1, consisting of an upper fixed switching contact piece 2 with an attached upper fixed contact rod 3, a lower movable switching contact piece 4 with a lower axially movable contact rod 5 and a metal bellows 6, is arranged is.
  • the switch contact pieces 2 and 4 with their contact rods 3 and 5 are located in an airtight and evacuated housing, consisting of an upper insulator 7 and a lower insulator 8 and a metal screen 9 which is at free potential.
  • the vacuum interrupter chamber 1 is accommodated in four insulating bodies 10, 11, 12, 13, which form the insulating housing when inserted or joined together.
  • the insulating bodies 10, 11, 12, 13 carry conductive coatings on parts of their surface as parts of the control electrodes 14, 15, 16.
  • the control electrodes 14, 15 are terminated at one end by an electrode ring 17, while their other end is in each case at another , cup-shaped control electrode 18, 19 is present.
  • the insulating bodies 10, 11, 12, 13 are connected to one another in a dielectrically tight manner by means of an elastic insulating ring 20 via clamping elements.
  • the thickness of the insulating ring 20 is as small as possible in terms of insulation technology; this means that the operating voltage between the two electrode rings 17 or the test voltage can be applied, which corresponds to the off state of the switch.
  • material with high electrical strength is preferably used for the insulating ring 20.
  • switching contact piece 2 and control electrode 14 are at connection potential
  • switching contact piece 4 and control electrode 15, on the other hand are at ground potential. Because of the symmetry of the arrangement, approximately half the connection potential will be established as the intermediate potential. Between switching contact piece 2 or 4 and metal screen 9 (including associated control electrodes 14 or 15 and 16) there is approximately the same potential difference, so that the inevitable field strength-related load reaches its lowest possible value in some sections of the gas gap. Taking into account both switching states, the most advantageous intermediate potential in terms of insulation technology is thus achieved. In Fig.
  • a switch pole is shown in which a complete te vacuum interrupter chamber 1 is housed with its parts in an insulating housing 25 which is pushed over the vacuum interrupter chamber 1, it being irrelevant whether the gas gap between the interrupter chamber 1 and the insulating housing 25 is subsequently poured out with hardening insulating material.
  • switch poles 14 and 15 are so close to one another that there is no capacitive coupling of the adjacent grounded metallic encapsulation or support structure parts 24 or other electrodes with the control electrode 16 located at free potential.
  • Such switch poles can also be accommodated as a three-pole arrangement in a common encapsulation.
  • switch poles of vacuum switches designed according to the invention are preferably suitable for factory-made, fully solid-insulated high-voltage switchgear or transformer stations where there are high requirements with regard to protection against accidental contact and with regard to small-scale and compact construction. It is also possible to use this switch pole in hermetically sealed, gas-insulated or in metal-enclosed, air-insulated switchgear.
