Definitions

  • the invention relates to a high-voltage circuit breaker with sulfur hexafluoride as the extinguishing and insulating medium, which flows through a filter with the aid of a circulating device.
  • SF 6 -insulated high-voltage circuit breaker described with a static filter. It turns out that such a filter arrangement is rather limited in its effectiveness. Furthermore, a blower piston switch for high voltage, which has a dynamic filter, has become known from German designation 20 33 853, with the help of a pump starting a gas flow through a filter independently of the extinguishing agent flow. The use of a pump proves to be relatively complex.
  • the invention has for its object to generate a gas flow for passage through a filter with simple means.
  • this object is achieved by heating and cooling gas to circulate the gas to be filtered in a separate volume connected to the circuit breaker volume.
  • An expedient development of the invention can consist in that the filter is provided with a bypass, that the bypass has a non-return valve with a blocking direction to the separate volume, and that in the connecting line between the filter and the separate volume a non-return valve or a non-return valve with a reverse blocking direction is arranged, and in that the bypass is directly connected to the circuit breaker volume with a connection side.
  • FIG. 1 shows a high-voltage circuit breaker with the associated separate volume including filter in a schematic representation
  • FIG. 2 shows a high-voltage circuit breaker according to FIG. 1 with a bypass to the filter
  • Fig. 3 shows the connection of a connection side of the bypass directly to the circuit breaker volume.
  • FIG. 1 shows a high-voltage circuit breaker 1 which is connected to a housing 4 as a separate volume via a connecting line 2 and an inserted filter 3.
  • the housing 4 is provided with an electric heater 5, which is switched on with the aid of an electric timer 6 at predefinable time intervals.
  • the time switch has a self-winding movement and is fed in via connection 7.
  • the heater is connected to the switch contact of the time switch via connection 8.
  • the arrangement according to FIG. 1 works in such a way that, in larger time intervals, a separate gas volume in the housing 4 in connection with the gas volume of the high-voltage power switch is heated for a certain time, so that the gas in the housing 4 expands and over during the heating time the line 2 through the filter 3 in the High-voltage circuit breaker 1 flows.
  • the heating is now switched off, so that due to the cooling in the housing 4, a slight negative pressure is created and, due to the associated suction effect on the gas volume of the high-voltage circuit breaker, gas flows out of this for filtering through the filter 3 into the separate housing 4.
  • This process repeats itself in constant change.
  • the volume of the housing 4 and its heater 5 are designed such that after a certain time the sulfur hexafluoride of the circuit breaker 1 has been circulated and passed through the filter 3.
  • the filter 9 is provided with a bypass 10, the bypass having a check valve or a check valve 12 with a blocking direction to the housing 4, and in the connecting line 11 between the filter 9 and the Housing 4 is a check valve or a check valve 13 is arranged with the reverse locking direction. It is thereby achieved that the heated gas from the housing 4 reaches the circuit breaker 14 via the bypass 10 without having to pass the filter 9, which represents a certain flow obstacle. It also prevents the filter from releasing moisture when heated gas flows through it.
  • bypass 15 is connected directly to the circuit breaker housing with a connection side, in order to improve the gas circulation the gas entry and exit points on the high-voltage circuit breaker are at a greater distance from one another.

Abstract

Dans un disjoncteur a haute-tension le gaz de coupage (SF6) est conduit a travers un filtre (3, 9) a des fins de nettoyage et de sechage. La circulation du gaz de coupage est assuree par un recipient (4) rempli de ce gaz qui est alternativement chauffe et refroidi. Le recipient est en liaison (2, 11) avec l'interieur du disjoncteur.
