Definitions
- the invention relates to a high-voltage circuit breaker according to the preamble of claim 1, such as e.g. known from DE-A-3211272.
- Another high voltage circuit breaker is for example from the German utility model G 93 14 779.1 and from the German patent application DE 29 47 957 known.
- the quenching gas flowing through the arc is in the arc area strongly heated and then flows at least partially in the axial direction of the arcing contacts in one Expansion space.
- the expansion space is through the housing of the switch that for example made of porcelain or a composite insulation material exists, limited.
- the present invention is therefore based on the object to create a switch of the type mentioned at which the quenching gas after blowing the arc before Outflow into the expansion space is sufficiently cooled.
- the extinguishing gas By redirecting the extinguishing gas according to the invention by more than 90 ° the extinguishing gas is not directly radially outwards the inner wall of the housing is directed, but flows towards the At least flow into the flow deflection device a backward component partially axially this out. This will make the flow path until it hits extended considerably to the inner wall of the housing. It is therefore sufficient cooling of the extinguishing gas until Impact on the inside wall of the housing.
- the invention provides that a nozzle body integrated into the flow deflection device is.
- the extinguishing gas flows out of the flow deflection device out at high speed and thus can distribute effectively in the expansion space.
- the nozzle body targeted control of the extinguishing gas flow is achieved causing turbulence or backflow of the extinguishing gas in the flow deflector is prevented.
- a further advantageous embodiment of the invention provides before that the flow deflection device is cylinder symmetrical trained and arranged coaxially to the arcing contacts are.
- a cylinder-symmetrical design of the flow deflection device is both manufacturing technology and construction particularly advantageous.
- a further advantageous embodiment of the invention provides before that the nozzle body attached to a cylindrical partition which is the extinguishing gas flow before the redirection of separates the extinguishing gas flow after the deflection.
- Such a partition prevents the Extinguishing gas flow before the deflection with the extinguishing gas flow after the redirection comes into contact, which leads to turbulence, Mixing and subsequent heating of the Guide the extinguishing gas behind the flow deflector could. It should be the total amount of extinguishing gas through the Flow deflector are forced.
- the invention can also be advantageously configured in this way that the nozzle body has a convex area, which faces a concave region of the flow deflection device and that between these areas there is an annular gap Nozzle is formed.
- This construction forms a simple and effective Nozzle to accelerate the flow of extinguishing gas.
- a further advantageous embodiment of the invention provides before that the deflection in the sense of the extinguishing gas flow an extinguishing gas cooling device in the form of a passage openings having subordinate body.
- the extinguishing gas flow is by such an extinguishing gas cooling device cooled further. Cooling is said to be related deionization of the present application of the extinguishing gas can be understood.
- An extinguishing gas cooling device can, for example, by a sponge-like metallic body can be realized that special can be advantageously designed cylindrical symmetrical. It can also be provided that the quenching gas cooling device a further deflection device for the extinguishing gas is arranged downstream is.
- the Flow deflection device and / or the nozzle body from one Insulating material, especially PTFE or PVDF.
- the insulating material can, especially if it is PTFE (Polytetrafluoroethylene), also add additional gas, that cools the extinguishing gas.
- PTFE Polytetrafluoroethylene
- the figure shows the breaker unit schematically in longitudinal section a high-voltage circuit breaker.
- FIG. 1 In the figure is an interrupter unit of a high voltage circuit breaker shown with a first, drivable Arcing contact 1, which is a second, fixed Arcing contact 2 faces.
- the first arcing contact 1 is coaxial from a likewise drivable first one
- the channel 6 in the form of an annular gap having.
- a mechanical compression device can also be used be provided for the extinguishing gas, in particular in the case of low-current arcs, an extinguishing gas blast of the Arc ensures.
- Extinguishing gas flow leads the extinguishing gas to one Flow deflecting device 9, which has a first PTFE body 10 and has a nozzle body 11 also made of PTFE.
- the nozzle body is attached to a partition 12, which coaxially surrounds the fixed arcing contact 2.
- the extinguishing gas cooling device 13 is formed by a hollow cylindrical metal braid, which Has openings for the extinguishing gas.
- the extinguishing gas cooling device can advantageously be made of copper, for example consist.
- the Flow deflection device 9 deflection of the extinguishing gas flow by about 180 °.
- the extinguishing gas then flows tangentially past the extinguishing gas cooling device and partly through it therethrough.
- the passage through the quenching gas cooling device takes place with reduced radial speed instead, so that effective cooling is guaranteed.
- a further deflection device is located behind the extinguishing gas cooling device 13 14 provided in the form of a cylindrical partition, which a direct discharge of the extinguishing gas from the Extinguishing gas cooling device 13 to the inner wall 15 of the housing 16 prevented.
- the extinguishing gas can thus enter the expansion space 17 in pre-cooled condition and with reduced radial speed enter.
