Definitions
- the invention relates to a switch-disconnector for gas-insulated switchgear with an arc quenching device comprising an extinguishing coil formed by a winding support and a winding with an electrically conductive arc running surface.
- JP 10228846A describes an arc extinguishing coil comprising a winding and a coil core and an arc guiding element extending to a fixed contact of the switchgear.
- the arc generated when opening the movable contact of the switchgear is moved over the arc guiding element to the arc extinguishing coil.
- a current impressed by the switching arc commutated to a running ring flows through the extinguishing coil and builds up a magnetic field, so that the arc root point, caused by the
- a known from EP 1064663 Bl based on the same principle arc quenching device for a gas-insulated switch disconnector has a coil-carrying winding body made of a conductive plastic and a Feldsteu- erelektrode and emanating from the winding, reaching close to the fixed contact, shiny metallic guide element on, the end of a certain minimum distance to the moving past this moving contact and the base of the fixed contact has.
- the movable contact passes the end of the baffle, the fixed contact base of the arc is taken over by the baffle and a current is conducted into the winding so that the base of the arc due to the magnetic field makes a rotating movement on the metallically bare last winding and in the current zero crossing goes out.
- the invention has for its object to provide an arc extinguishing coil, which is inexpensive and compact and has a high and reliable fire fighting capacity.
- An important feature combination of positioned near a fixed contact of the circuit breaker arc quenching device is that its ironless executed quench coil is assigned on the side of the arc root, a metallic race with raised outer edges, and the quenching coil on the winding support and an outer and inner shells of non-conductive material is arranged insulated to the outside, and the two ends of the winding are connected to the one fixed contact and the other to the raceway.
- arc quenching device which can be arranged close to the fixed contact, a parallel to the surface of the race aligned and focused on this area magnetic field is generated directly with the resulting upon separation of the switch contacts switching arc, so that the base of the without additional guide immediately to the exposed part of the race commuting arc a fast and controlled, that is, executes rotational movement limited to the annular arc running surface while being well cooled and rapidly extinguished.
- the inner jacket of the ironless quenching coil also forms a gas circulation opening, so that the existing gas in the switchgear circulate on the quenching coil and can provide for improved cooling of the arc.
- the live parts of the quenching coil are covered by the plastic sheath (outer sheath, inner sheath, winding carrier) to the outside so that re-ignitions are prevented by hot plasma arc. Equally excluded is a pre-ignition of the arc when closing the switch, so that the extinguishing coil can not be destroyed by the resulting very high current at power after a short circuit.
- the arc quenching device is also simple and compact.
- Edge of the inner shell and the outer shell each formed an inwardly directed annular collar on which the raceway and resting on this extinguishing coil are supported.
- the two collars end at liberation of an annular gap at a distance from each other.
- the annular gap defines a geometrically defined arc running surface of the centrally arranged above this race.
- the arc running surface is dimensioned in the diameter so that a short-circuiting of the arc is excluded on its career.
- the winding of the quenching coil arranged in the winding carrier is located - isolated by a circumferential web of the winding carrier - exactly above the arc running surface and above the annular gap.
- a maximum transverse magnetic field acts on the arc base point on a narrow trajectory, so that its particularly high rotational speed is ensured.
- the quenching device which is opposite the raceway, it is insulated from the outside by the fact that a cover plate extending to the outer jacket and to the inner jacket is integrally formed on the winding carrier.
- the cover plate is held by locking elements on the inner and outer sheath, so that the extinguishing coil is fixed in total between the inner and outer sheath in a simple way.
- the raceway has a U-shaped cross-sectional profile, i. at the inner and outer edge raised legs which bear against the inner and outer sheath.
- the U-shaped design of the race and the resulting electrical control allows the short distance to the fixed contact and thus possible without additional guide elements rapid commutation of the arc to the arc quenching device, despite the small distance without the risk of re-ignition of the already deleted arc from the moving contact to the fixed contact.
- On the raised inner leg of the guide ring can also advantageous one end of the winding of the quenching coil - for example by means of tabs or Sch Strukturver connection - are conductively attached.
- the arc quenching device is attached by means of attached to the outer jacket mounting straps on the fixed contact.
- the second end of the winding is held by a contact element on one of the fastening tabs and so galvanically connected to the fixed contact.

- FIG. 2 shows a perspective view of the arc-extinguishing device
- FIG. 3 is a plan view of the arc quenching device
- Fig. 4 is a sectional view of the arc quenching apparatus taken along the line I-I in Fig. 3;
- Fig. 5 shows a detail "X" of the arc quenching device of Fig. 4;
- Fig. 6 is an exploded view of the arc quenching device.
- FIG. 1 shows the contact system of a switch-disconnector 1 arranged inside a gas-filled switchgear, which has a fixed contact 2, a moving contact 4 pivotable by means of a switching shaft 3 and a grounding contact 5.
- the moving contact 4 is on the switching shaft 3 and the fixed contact 2 is held on a support 6.
- an arc quenching device 7 With the fixed contact 2 is an arc quenching device 7, which is arranged close to the contact point between the fixed and the moving contact, galvanically connected, so that formed during pivoting of the moving contact 4 in the open position shown in Fig. 1 arc quickly - and without additional guide elements - commute to the arc quenching device 7 and can be reliably deleted.
- the arc facing lower level of the arc quenching device 7 is arranged at a certain angle to the contact point, which - relative to the horizontal - preferably can be between 0 and 60 °.
- the core of the arc quenching device 7 is a quenching coil 8, which in the present embodiment consists of a two-layered, arranged on an annular winding support 10 th winding 9 consists of enameled copper wire.
- the winding support 10 comprises a circumferential web 11 with a wide cover plate 12 which struts away from its upper edge and a narrow leg 13 which struts away from its lower edge to one side and consists of a nonconductive plastic, preferably a UV-resistant thermoset or thermosetting plastic.
- the quenching coil 8 rests with the encircling leg 13 on or in a raceway 14 with a U-shaped cross section, which consists of an electrically conductive metallic material, such as brass, copper, aluminum or bronze.
- the outer jacket 20 surrounds the outer peripheral surface of the quenching coil 8 including the raceway 14, which is bent on a lower, inwardly Ring collar 21 of the outer shell 20 is supported and the outer edge 14 b rests against the inner surface of the outer jacket 20.
- the inner peripheral surface of the quenching coil 8 is covered with an inner shell 22 having a lower, bent-out annular collar 23 on which the raceway 14 also rests.
- the winding support 10 with the winding 9 (extinguishing coil 8) is held on the side opposite the race 14 by locking elements 24 which are formed on the inner surface of the outer jacket 20 and on the outer surface of the inner jacket 22.
- the two bent collars 21, 23 terminate at a distance from each other, so that at the - the contact point between the fixed and moving contact facing - lower side of the arc quenching device 7, an annular gap 27 and a limited by this bilateral annular arc running surface 25 for the Lichtbogenhetician, which is located directly under the winding 9 of the quenching coil 8, remains free.
- the circular shape of the race 14 with the raised edges 14a, 14b causes a very good electrical Ab- control to adjacent live components and the ground potential, so that on the one hand a compact, cost-effective design is possible and on the other hand - despite the small distance to the fixed contact - a Re-ignition of the arc is excluded from the moving contact on the fixed contact.
- a compact, cost-effective design is possible and on the other hand - despite the small distance to the fixed contact - a Re-ignition of the arc is excluded from the moving contact on the fixed contact.
- Running ring 14 via the contact element 18 a good contacting tion between the winding 9 and the race 14 and thus achieves an intense effect of the magnetic field generated by the winding 9 on the arc.
- the inner jacket 22 and the outer jacket 20 with the attachment tabs 19 formed thereon and the winding carrier 10 are made of a non-conductive plastic and cover all live parts of the quenching coil 8 completely off, so that caused by emerging plasma of the arc Neuentzünditch are excluded.
- the large, central gas circulation opening 26 generated by the inner jacket 22 also ensures a good circulation of the gas surrounding the switch disconnector, so that the rotating arc constantly comes into contact with new, cool gas and its extinguishing behavior due to the extracted energy is further improved.
