Definitions

the present invention relates to a high-voltage switch according to the preamble of claim 1.
This switch has an insulating gas-filled metal container and a built-in container quenching chamber.
the quench chamber includes a housing aligned along an axis, an arcing contact assembly held in the housing, an exhaust volume limited by the housing, and an exhaust passage for exhaust gases passing through the wall of the housing.
the outlet channel opens with a predominantly aligned in the direction of the axis portion into the container.
the switching chamber is at high voltage potential and occur when switching off a short circuit current generated by the switching arc hot exhaust gases through the outlet channel in the metal container at ground potential.
the hot exhaust gases have a low density and therefore locally temporarily reduce the dielectric properties of the insulating gas present in the metal container.
a high voltage switch of the type mentioned is described in the earlier European patent application file number EP 06 40 5112.1 , registered on 14.3.2006.
This switch includes a quench chamber having an arcing contact assembly held in a housing and an exhaust unit integrated into the housing which has an exhaust volume defined by the housing and an outlet for exhaust gases routed through the housing.
About the exhaust unit in a coaxial arrangement designed in the manner of a pot exhaust module is slipped.
the housing and pot define a mouth portion of an exhaust passage with an electrically shielded, axially aligned exhaust port.
the exhaust gases therefore affect the quality of a gas insulation between an extinguishing chamber receiving, Insulating gas filled metal container and the housing in general only slightly, so that the switch can be loaded with high-power switching arcs long period, as this has a reduction in the frequency of the high voltage of, for example 50 to 16 2/3 Hz result.
the invention has the object to provide a high voltage switch of the type mentioned, which is characterized by a high level of reliability.
an annularly guided around the axis, electrically shielded edge is arranged on an end face of the mouth portion outwardly limiting housing approach.
a guided in the mouth section exhaust gas flow from the housing approach and can now enter as radially outwardly limited gas jet into the metal container.
the hot gas jet which has a low density and therefore only comparatively weak dielectric properties, is carried away at the edge of electrically heavily loaded areas on the front side of the housing projection because of the stall. This avoids that hot exhaust gases are due to the Coanda effect of the inner surface of the housing approach over a convex curved surface of the front side on the also convex curved outer surface of the housing approach are guided and this flow through dielectrically heavily loaded areas.
Such dielectrically heavily loaded areas are mainly located on the front side and a subsequent to the front side portion of the outside of the housing approach, ie in areas where the radii of curvature of the field-loaded surfaces of the housing approach are relatively small.
the edge has a small radius of curvature relative to the radii of curvature of the field-loaded surfaces of the housing projection. If the edge delimits an inner surface of the housing projection in the direction of flow of the exhaust gases, the flow separates in a defined manner from an easily positioned, dielectrically relieved point. In order to achieve good dielectric properties, in this case the edge is offset axially relative to a convexly curved surface of the front side causing the electrical shield, radially inward and / or opposite to an edge delimiting the end side in the flow direction against the flow direction. If a step is provided in the end face extending from the edge to the edge, then the exhaust gases can come off the housing projection even when the flow rate is low, and the edge is at the same time particularly electrically shielded.
a flow ring guided around the axis is provided on an outer surface of the housing section associated with the mouth section arranged an electrically shielded second edge. This edge is offset radially outwards relative to the outer surface.
the flow ring advantageously has a profile designed in the manner of a sawtooth with a steep flank arranged counter to the flow direction of the exhaust gases. Such a flank causes a secure separation of the flow at the second edge forming the tip of the sawtooth and thus enables, together with the edge provided on the housing projection, the formation of a dielectrically favorable free jet with an annular cross-section.
Insulation distances can be maintained if a tubular housing section with a diameter adapted to the housing projection adjoins the conically widened housing section.
the in Fig.1 shown high voltage switch has a with an insulating gas, such as based on sulfur hexafluoride, nitrogen, oxygen or carbon dioxide or mixtures of these gases, such as air, with a pressure up to a few bar filled and largely tubular shaped metal container 1, in which a quenching chamber. 2 is arranged.
the quenching chamber is kept electrically isolated in the metal container 1 with the aid of a post insulator not shown.
the quenching chamber 2 includes a housing 3, which is formed substantially symmetrically with respect to an axis A and inside the housing contains an arcing contact arrangement 4 with two relatively movable arcing contacts 5, 6.
the quenching chamber housing 3 also accommodates a rated current contact arrangement provided for guiding the continuous current and connected in parallel with the arcing contacts 5, 6, but this is not shown for reasons of clarity.
the quenching chamber housing is of an insulating tube 7 and two at the ends thereof formed gas-tight fastened metal hollow bodies, of which only the right end of the housing 3 forming hollow body 8 is shown.
the second hollow body, not shown, forms the left end of the housing 1 and is mounted on the also not apparent support insulator.
the two hollow bodies are generally made of cast metal, for example based on steel or aluminum, and serve to hold hot exhaust gases 9, which are formed in a switching operation in the contact assembly 4 and the leadership of the switch current and the shielding of parts of the quenching chamber 2, in the operation of the switch, ie when subjected to high voltages of up to one hundred and more kV and carrying 50 and more kA short-circuit currents, are exposed to strong electric fields.
the hollow body 8 limits an exhaust volume 10 and receives a gas mixing device 11 arranged in the exhaust volume. Via a guided through the housing 3 exhaust passage 12, the exhaust gases 9 are discharged from the exhaust volume 10 to the outside in the insulating gas-filled metal container 1.
the switch current is fed from the right through a current-conducting bolt 13, which is electrically conductively inserted into a cup-shaped sleeve 14.
the bottom of the cup resp. the sleeve 14 carries the gas mixing device 11.
the edge of the cup is guided radially outward and fixed by means of screw 15 to a border which limits an axially aligned opening of the hollow body 8, through which the pin 13 is guided to the outside.
the outlet channel 12 terminates in the metal container 1 with an outlet section 16 formed axially and designed as a hollow cylinder.
the outlet section 16 is bounded inwardly by a tubular section 17 of the housing 1 and outwardly by a tubular housing extension 18 which surrounds the housing section 17 at a distance ,
the housing extension 18 is part of a sleeve 14 holding and connected thereto by the screw 15, cup-shaped end member 19 of the hollow body 8, to which the element 19 is attached via not shown, radially guided webs or screws.
a flow ring 24 is formed with an annularly guided around the axis tear-off edge 25.
the edge 25 is arranged offset radially outwards relative to the surrounding outer wall of the housing 3 or of the housing section 17.
the flow ring 24 has a profile designed in the manner of a sawtooth with a counter to the flow direction of the exhaust gases 9 arranged steep flank 26.
a conically widening housing portion 27 At the flow ring 24 includes in the flow direction of the exhaust gases, a conically widening housing portion 27 at.
flat flank 28 of the flow ring 24 has a greater slope than the flared housing portion 27 to which a tubular housing portion 29 connects with a matched to the housing extension 18 diameter.
the exhaust gases 9 are guided in the mouth portion 16 in the axial direction from right to left and flow along the inner surface 22 of the housing projection 18 and the outer surface of the housing portion 17.
At the trailing edge 21 terminates an adhering to the inner surface 22 boundary layer of the exhaust gases, so that the Exhaust gases therefore dissolve from the housing approach 18 and can enter into the metal container 1 as a beam in electrically lightly loaded areas.
the exhaust gases which have comparatively weak dielectric properties due to their low density, reach areas of high electrical stress, such as, in particular, a convexly curved surface of the end face 20 and an adjoining, likewise convexly curved section of the outer surface of the housing projection 18
the convexity of the aforesaid surfaces is necessary to control the electrical field prevailing between the grounded metal container 1 and the quenching chamber 2 at high voltage potential, ie to reduce strong local electric fields at the end face 20 and at the sharp trailing edge 21 avoid.
the boundary layer adhering to the inner surface 22 could extend to the convexly curved end face 20 and the adjoining surface section, and thus the hot exhaust gases could be guided into areas which are electrically comparatively highly loaded.
the detachment of the exiting from the mouth portion 16 exhaust gases 9 from the housing extension 18 is facilitated by the fact that the radius of curvature of the tear-off edge 21 is compared to the radii of curvature of the surface of the end face 20 dimensioned much smaller. Such a small radius of curvature may therefore possibly lead locally to undesirably high electric field load.
the tear-off edge 21 is arranged offset radially relative to the electrical shielding, curved surface of the end face 20 to form the step 23 radially inwardly, but also opposite the end face 20 axially against the flow direction of the exhaust gases. It is so ensures that the Auspuffgasströmung 9 not only safely detached from the housing extension 18, but that at the same time the tear-off edge 21 is particularly effectively shielded against the prevailing in the metal container electric field.
the flow ring 24 formed in the outer wall of the housing section 17 prevents the hot exhaust gases 9 passing from the mouth section 16 into the metal container 1 being guided along the housing section 27, since the exhaust gas flow can detach from the outer wall of the housing section 17 at the spoiler lip 25. Both demolition edges 21 and 25 can thus cause the formation of the free jet 30, which is performed in a particularly advantageous dielectric from the mouth portion 16 without further housing contact directly into the provided in the container 1, cool and therefore dielectrically high-quality insulating gas.
the steep flank 26 facilitates the detachment of the exhaust gas flow 9 from the housing 3.
the flatter flank 28 of the flow ring has a greater pitch than the conically widening housing section 27.
the housing portion 29 has a largely matching with the housing extension 18 diameter, the predetermined by the geometrical dimensions of the metal container 1 insulation distances between the grounded container wall and the high voltage potential housing approach 17 can be maintained.
