Definitions
- the invention relates to coated quenching plates for arc extinguishing chamber in switchgear, especially in circuit breakers.
- Such quenching plates are known from E. Vinaricky "Electrical Contacts, Materials and Applications", Springer Ver ⁇ lag 2002, ISBN3-540-42431-8, pages 134-142.
- extinguishing chambers are known in the switching devices.
- a subdivision of arcs in partial arcs takes place in Lösch ⁇ chambers, which contain an array of quenching plates, according to the separation principle.
- a quenching chamber operating according to the deionization principle a plurality of typically 1 mm thick metal sheets are arranged parallel to one another or fan-shaped and insulated from one another.
- Ferromagnetic materials are used as the material for the quenching plates, since the magnetic field which accompanies the arc is aimed in the vicinity of a ferromagnetic material through the quenching plates which are better magnetically conductive. This creates a suction effect in the direction of the quenching plates. In addition to a magnetic blowing field generated by the arc itself, this suction effect causes the arc to move to the arrangement of the quenching plates and to be divided between them.
- the present invention has for its object to reduce the disadvantages of known arc extinguishing combs and to increase the life and / or the short-circuit breaking capacity of switching devices equipped with it.
- Inventive quenching plates consist of a ferromagnetic Grund ⁇ material and are coated. But you are not just with a metal such. As silver or copper whose melting point is not higher than that of the ferromagnetic material and preferably has a higher electrical conductivity than this, but rather they carry a layer of a Verbund ⁇ material, which except a first component whose melting point is not hö ⁇ ago is than that of the ferromagnetic material and has a better conductivity than the ferromagnetic material, also has at least a second constituent part which melts higher than the first constituent and also has a higher evaporation point than the first constituent.
- the higher melting A second constituent which does not initially melt with the action of an arc, is intended to prevent the molten conductive or highly conductive first constituent, which is melted under the action of an arc, from being splashed.
- the amount and the melting point of the second component are chosen so that this effect is achieved.
- Switching devices which have extinguishing chambers equipped with extinguishing plates according to the invention are distinguished by a longer service life compared with the prior art and / or an improved short-circuit breaking capacity.
- the electrically conductive or highly conductive first component should promote a migration of the arc on the quenching plates and direct the electric current transported by the arc in the ferromagnetic material.
- the first constituent is preferably selected such that its vaporization point is also reached under the effect of light arc, because as a result of evaporation of the first constituent, so much energy can be withdrawn from the arc that it is thereby interrupted.
- ferromagnetic base material is not only soft iron in question, but son ⁇ every soft magnetic material, in particular nickel and cobalt and soft magnetic alloys of iron, nickel and Kolbalt.
- the second component of the layer is preferably selected so that it can bind well to the first component under the action of arcing on the arc.
- especially materials are those whose melting point is higher than that of the ferromagnetic material and its evaporation point also higher than the evaporation point of the ferromagnetic material.
- the melting point of the second component is even higher than the evaporation point of the first component.
- Particularly suitable are the refractory metals tungsten, molybdenum and tantalum and their carbides, nitrides and suicides, which can be used individually or in combination.
- the volume ratio between the first constituent and the second constituent is expediently between 5 to 95 and 85 to 15, more preferably between 30 to 70 and 80 to 20, even better between 40 to 60 and 70 to 30. Preference predominates the proportion of the first component.
- the layer of the composite material also contains a third constituent which is selected from the group of oxides, carbides, borides and nitriles of the elements of main groups II, III, IV and VIII and subgroups III to VII of the Periodic Table of the Elements is.
- a third constituent which is selected from the group of oxides, carbides, borides and nitriles of the elements of main groups II, III, IV and VIII and subgroups III to VII of the Periodic Table of the Elements is.
- An addition of one or more substances of the third group improves the arc running behavior on the coated quenching plate, so that the arc wan ⁇ easier and faster to an arrangement of quenching plates in an arc-quenching chamber and in this arrangement, in particular in a package of several parallel to each other or fan-shaped arranged quenching plates occurs.
- Particularly suitable as the third constituent of the composite material are the substances from the group of titanium dioxide (TiO 2 ), aluminum oxide (Al 2 O 3 ), magnesium oxide (MgO), manganese oxide (MnO), niobium oxide (NbO), nickel oxide (NiO), cerium oxide (CeO 2 ), chromium oxide (Cr 2 O 3 ), lanthanum oxide (La 2 O 3 ), zirconium oxide (ZrO), yttrium oxide (Y 2 O 3 ), boron carbide (B 4 C), silicon carbide (SiC), zirconium carbide ( ZrC) 1 aluminum nitride (AIN), boron nitride (BN), titanium nitride (TiN), titanium boride (TiB 2 ) and zirconium boride (ZrB 2 ).
- the third component is expediently provided at the expense of the second portion in the composite material. Therefore, the volume ratio between the first constituent and the sum of the second and third constituents is desirably between 5 to 95 and 85 to 15, more preferably between 30 to 70 and 80 to 20, more preferably between 40 to 60 and 70 to 30. Also in In this case, the proportion of the first constituent preferably outweighs the sum of the second and third constituents.
- the layer of composite material is desirably between 0.05 mm and 0.3 mm thick, preferably about 0.1 mm thick. It can be carried on a ferromagnetic strip by rolling a strip of the composite material, in particular by hot-roll plating. Another possibility is to apply the components of the layer by thermal spraying (flame spraying) onto a ferromagnetic sheet, the coating preferably being compacted and leveled by rolling.
- thermal spraying flame spraying
- a tungsten carbide powder may be applied to a sheet of soft iron and a composite layer of iron and tungsten carbide may be formed by pressing the particles of tungsten carbide powder into the surface of the soft iron by cold rolling.
- an intermediate layer is provided between the composite layer and the ferromagnetic base material, which improves the adhesion and hinders diffusion.
- Nickel which still has the advantage of being ferromagnetic, is particularly suitable for this purpose.
- the intermediate layer is preferably applied by electroplating, advantageously in a thickness between 3 .mu.m and 20 .mu.m, in particular approximately 10 .mu.m.
- Splitter plate can be formed by bending and punching and installed in a low-voltage switching device.
- a strip is plated by cold-rolling plating, which consists of 55 vol .-% silver and 45 vol .-% molybdenum. After the cold rolling process, the thickness of the
- Quenching plate 1 mm wherein the composite layer of silver molybdenum is 0.1 mm thick.
- the quenching plate produced in this way can be formed by stamping and bending and installed in a low-voltage switchgear.
- a 1 mm thick sheet of soft iron is first galvanically provided with a 10 micron thick nickel layer and then a 0.2 mm thick
- Fused composite layer which consists of 40 vol .-% copper and 60 vol .-% tungsten carbide.

After hot-roll plating, the thickness of the strip is 1.2 mm, with the thickness of the composite layer of silver and tantalum being 0.15 mm. From the band are formed by bending and punching quenching and in a
- Low-voltage switchgear installed. 5. On a sheet of soft iron with a thickness of 1, 2 mm, a tungsten carbide powder is applied and pressed by cold rolling into the surface of the soft iron. The powder is applied to the soft iron in an amount such that the latter still forms between 50% and 60% of the surface of the quenching plate. This creates a functional layer of iron and tungsten carbide on the surface of the soft iron.
