Definitions
- the invention relates to a device for deleting itself between contacts of a switchgear, a transformer or Busbars and Like. Forming arc.
- a disadvantage of such known devices is, inter alia, that the arc must first be expanded before it actual quenching chamber is supplied. It can, in particular in switchgear, transformers and. Like. That in a housing are arranged, to damage and thus to a reduction the service life of the housing.
- DE 43 45 170 A1 also describes a device for extinguishing known from arcs in switchgear, in which after training an arc this first with a photosensitive and a light-insensitive (e.g. magnetic) sensor is detected. The Sensor signals then activate an energy store that is stored in a Induction coil of a short circuiter generates a high current. As a result of Forces caused by the induction current in vacuum cup-shaped metal parts, a metallic short circuit generated that bridges the arc.
- a photosensitive and a light-insensitive (e.g. magnetic) sensor is detected.
- the Sensor signals then activate an energy store that is stored in a Induction coil of a short circuiter generates a high current.
- a metallic short circuit generated that bridges the arc.
- DE 297 15 775 U1 is also one of DE 43 45 170 A1 corresponding device known, but not a separate Energy storage needed. Rather, they activate the arc Detecting sensors when an arc occurs a thyristors comprehensive circuit device which is in series with the induction coil of the short circuiter is switched. The one made of thyristors and induction coil existing series connection is directly to the busbars connected so that when an arc occurs corresponding short-circuit current first through the thyristors and Induction coil flows. The current-carrying induction coil then causes again a corresponding metallic short circuit that the Arc bridged.
- the present invention has for its object a Specify device of the type mentioned, with which a between the contacts of a switchgear, a transformer or Busbars and Like. Forming arc in a simple manner can be deleted quickly and safely.
- the invention is essentially based on the idea that Electric arc with the help of a metallic short circuit bridge bridge and thereby quickly extinguish it.
- Electric arc with the help of a metallic short circuit bridge bridge and thereby quickly extinguish it.
- This invention is implemented by a device with Arc guide rails, which are the contacts, one of which is the respective Arc goes out, connects with quenching coils.
- the quenching coils are After reaching the arc, electricity flows through and generate one magnetic field each, which is then in the corresponding coil magnetizable metal core moves until the Short-circuit bridge contacted and thus the arc electrically shorts.
- the Arc rails themselves on their facing the short circuit bridge Ends are coil-shaped so that separate quenching coils are not required can.
- the metal core is made of a ferromagnetic first Partial core and a second partial core made of copper put together.
- the first part of the core should be a quick shift of the entire metal core cause as soon as the quenching coil of electricity is flowed through, while the second core as the contact part Ensures connection with the short-circuit bridge.
- 1 is a device according to the invention designated. This is one with the three infeed contacts 2-4 For reasons of clarity connected transformer, not shown, the respective connection between the transformer and the Infeed contacts 2-4 take place via an electrically insulated line 5 (Fig.2). In addition, the feed contacts 2-4 of the transformer connected to the power rails 6-8 of a high-voltage network.
- the device 1 comprises three made of copper existing arc guide rails 9-11, the first end of each 12-14 connected to the feed contacts 2-4 and the second end 15-17 is coil-shaped and thus the function of an arcing coil owns.
- the mutual distance 18 of the arc guide rails 9-11 is in a middle area between contacts 2-4 and the quenching coils 15-17 by leaps and bounds to about half the distance he was in the area of Has feed contacts, reduced.
- each of the three quenching coils 15-17 Slidable metal core 19-21 is guided and the contacts 2-4 facing end of a first partial core 23 made of iron and its opposite end made of a second partial core 24 made of copper consists.
- the second partial core 24 is at the end of each Quenching coil 15-17 arranged contact disc 28 with the quenching coil electrically connected.
- short-circuit bridge 25 made of copper, whose distance 27 from the respective metal core 19-21 is selected in such a way that it is in the intended use of the switchgear etc. no arcing occurs.
- the arc 26 then migrates over the turns of the Quenching coils 15, 16, so that current flows through them, so that builds up a magnetic field inside the respective coil 15, 16.
- This Magnetic field pulls the first partial core 23 of the respective metal core 19, 20 abruptly in the middle of the corresponding coil 15, 16 and moves thus the second partial core 24 made of copper in the direction on the short circuit bridge 25 until it reaches the bridge and the arc 26 is electrically short-circuited and goes out.
- the invention is of course not based on the above described embodiment limited.
- Reduction of the spatial limitation of the arc's distance Arc tracks are not abruptly reduced from one another, but can also change continuously.
