Definitions

  • the invention relates to a gas pressure switch with two mutually movable contact pieces.
  • Such a pressure gas switch is from the Toda attachment, H. u. a .: Development of 550 kV 1-Break GCB (Part II) - Development of Prototype; in: IEEE Transactions on Power Delivery, Vol. 8, No. 3, July 1993, pp. 1192-1198.
  • the displacement of the one contact piece is over a Transfer lever mechanism to the other.
  • two Diverter lever available, on which two rods can be rotated are attached. Both contact pieces are over the rods symmetrically with opposite ends of the bellcranks connected.
  • the lever mechanism with the rods must be one electrical insulation included since he is with both Contact pieces is connected and thus the switching path bridged. Isolation and electrical shielding are complex.
  • the bellcranks inevitably protrude laterally the size of the switch chamber; this results in a quite large diameter.
  • a high-voltage switch is also known from EP 0 313 813 A1 known with two mutually movable contact pieces, only one of which is driven directly. On this contact piece is an insulating nozzle with a this coaxially surrounding conductive shield attached.
  • each of the two gears meshes with one of the two racks and another in another Rack to which that is not with the insulating nozzle connected contact piece is coupled.
  • the effect Gears a reversal of the direction of movement that So contact pieces always move in opposite direction.
  • the gears need for a lot be designed for high loads because they Switching off suddenly at high speeds get abandoned.
  • the high voltage switch works with one Blowing device for the arc. This will Decomposition products that the arc with its high Generates energy, very widely distributed inside the switch and get into the rack and pinion gear. This reduces the reliability of the high-voltage switch in the case of a multi-year operation.
  • the electrodes control the electric field in the open Switching distance.
  • the stroke length along the outer wall of the Isolierstoffdüse can not be much larger than that Shot distance can be executed in SF6.
  • the stroke distance is the distance between two conductive Split along a thread that is on the shortest path between these parts.
  • the invention has for its object a low-maintenance and reliable pressure gas switch create, with a high switching off Contact separation speed with low drive energy is achieved.
  • each bell crank in the Center axis of the gas pressure switch can be with produce the same diameter as conventional ones Gas pressure switch. This is particularly beneficial if he gas-tight as an outdoor switch with a porcelain insulator is encapsulated. The cost of a porcelain insulator increase significantly with its diameter.
  • the Lever mechanism is a particularly simple and robust Means to reverse movement of the contact pieces to evoke. Because the power transmission over the The insulating mechanism takes place, the lever mechanism needs no insulating elements themselves (e.g. insulating rods) to contain.
  • the cup-shaped contact unit body according to claim 2 provides for a dielectric shielding of the bell crank with his swivel joints against the point of interruption.
  • the polytetrafluoroethylene ring or rings according to claim 8 ensure that the Power transmission element on the inner wall of the Hollow cylinder.
  • the power supply has the shape of a tube and according to Claim 9 of the bell crank housed in this tube is, this is simple and special effectively dielectric shielded.
  • the lever mechanism It is also very important to protect against decomposition products simply possible.
  • a tubular power supply those used in conventional Gas pressure switches is used (for example in a Compressed gas switch according to page 4 in the company brochure "SF6 circuit breaker with spring energy drive. 72.5-170 kV ", A22 V.7.104 / 0993 DE from AEG Aktiengesellschaft, D-34123 Kassel-Bettenhausen).
  • the diameter of the one Lever mechanism equipped compressed gas switch remains So unchanged compared to conventional pressure gas switches.
  • a lever mechanism made of metal according to claim 13 stands out for its stability; this has a special effect advantageous with the two (long) poles attached to the Bellows are attached.
  • FIG. 1 shows a longitudinal section through a vertical switch pole of a pressure gas switch in the off position.
  • the gas pressure switch is filled with insulating gas, for example SF 6 , and is laterally surrounded by a tubular insulator 1.
  • insulating gas for example SF 6
  • switch type it is an outdoor switch.
  • the gas pressure switch has two in opposite directions along its Center axis M movable contact pieces 2 and 3, the form an interruption point.
  • the contact piece 2 is a contact pin and the bottom of a pot-shaped Contact unit body 4 attached.
  • the contact unit body 4 surrounds the contact piece 2 and the central axis M of the gas pressure switch coaxial and points with its opening towards the point of interruption, and down.
  • the contact unit body 4 extends telescopically into one tubular, open towards the point of interruption Part of a power supply 5 (for the contact piece 2) and can be moved out of it.
  • the power supply 5 also coaxially surrounds the central axis M of the Gas pressure switch.
  • a bell crank 6 arranged, whose axis of rotation 17 is the longitudinal axis of the gas pressure switch in cuts at a right angle.
