Definitions

  • the invention relates to the field of electrical power generation and transmission. It relates to a circuit breaker according to the preamble of the independent claim, which in particular in power plants, substations and other facilities of the electric power supply for switching on and off of operating and overcurrents, in particular in the range of medium or high voltage, is used.
  • Such a switch is for example from the European patent applications EP 0 696 040 A1 and EP 0 951 039 A1 known.
  • blow piston switch in which the blow piston is coated with a layer of heat-resistant plastic such as PTFE or polyamide to serve as electrical shield against the contact piece, or to prevent the formation of bases of the switching arc on the blow piston.
  • a layer of heat-resistant plastic such as PTFE or polyamide
  • a circuit breaker according to the invention which can be switched between a closed position and an open position, so that in the open position, an interruption path is formed, which comprises an arcing space; comprises a standing with the arc chamber storage volume for an extinguishing gas, which storage volume has an inlet for the quenching gas, further comprising a valve is provided at the inlet, which comprises a shut-off device, by means of which the inlet is closable.
  • the shut-off body has a heat-insulating coating. The heat-insulating coating serves to avoid plastic deformation of the shut-off.
  • the circuit breaker according to the invention which can be switched between a closed position and an open position, comprising a first power connection and a second power connection, wherein in the closed position between the first power connection and the second power connection an electrically conductive connection is formed, in the off position between the first power connection and the second power connection an interruption path is formed, wherein the interruption path comprises an arc space, which is formed between a first, electrically conductively connected to the first power terminal contact element and a second, electrically conductively connected to the second power terminal contact element, standing with the arc chamber in gas exchange storage volume for a quenching gas, which storage volume comprises an inlet for the quenching gas, and wherein at the inlet a valve is provided which comprises a shut-off body, by means of which the inlet is closable, the shut-off body has a heat-insulating coating. Again, the heat-insulating coating serves to prevent plastic deformation of the shut-off.
  • a plastic preferably a polymer
  • a thermoset is used because this remains rigid up to a decomposition temperature and thus in particular a drop formation is prevented.
  • Such droplet formation occurs partly in elastomeric and in particular in thermoplastic plastics, and often leads to flame formation at temperatures in the range or above the decomposition temperature of the corresponding plastic, in particular by igniting droplets or droplets formed.
  • an epoxy resin or epoxy resin system is used as the plastic.

  • E modulus of elasticity
  • this leads in conjunction with a solid, irreversible material compound, as formed between shut-off and heat-insulating coating, to increased rigidity, especially in annular shut-off, and thus to a reduction of plastic deformation of the shut-off during the turn-off.
  • a material is selected for the heat-insulating coating, in particular a plastic as described above, which has a thermal coefficient of linear expansion ⁇ with ⁇ ⁇ 20 ⁇ 10 -6 / K, preferably ⁇ ⁇ 15 ⁇ 10 -6 / K, and more preferably ⁇ ⁇ 10 ⁇ 10 -6 / K.

Shortly after the beginning of this movement, the movable rated current contact 8 separates from the upper fixed rated current contact 6, whereby the rated current path is interrupted and the current commutated to the Abbrandschaltan Aunt 10. Something later, the switching pin 14 is pulled out of the contact tulip 11. Between these contact elements, an arc 17 forms, which extends at the end of the switching movement through the arc chamber 16, which was opened by the movement of the switching pin 14 via the switching path.
