Definitions

the invention relates to a switching chamber or quenching chamber for a circuit breaker, especially for high voltage systems according to the preamble of the main claim.
the invention further relates to a circuit breaker with such Switching chamber.
switches are regular, in particular a small volume version of circuit breakers to allow switching chambers or extinguishing chambers to be used, which comprise an arc resulting from a switching operation, which is deleted there.
This isolation path is from an isolation area a wall of the corresponding switching chamber, there is made of a non-conductive material, bridged.
the closed state of a conventional circuit breaker with such a switching chamber occupies the switching chamber pin-like and displaceable along a switch axis Switched piece on, which at one end of a ring or tulip contact can be included as a second contact piece.
Such switching chambers and circuit breakers bring the Disadvantage with that, with switching operations, of switching arcs be accompanied, hot burned on the Wall of the switching chamber can be thrown, and indeed in the isolation area.
This burn-off material usually also consists of metallic Abbrandteilchen can spread over large areas of the wall of the switching chamber, which brings a weakened isolation ability with it.
in switching operations in a wide range charges be induced on surfaces of the wall, creating an electrical Field in the switching chamber and thus a behavior of a Switching arc can be influenced, causing a deletion of the switching arc complicate and the isolation ability of the circuit breaker in the open state, at least continue after a larger number of switching operations can weaken.
the invention is therefore based on the object, a switching chamber and to develop a corresponding circuit breaker, with which the mentioned disadvantages are minimized can and which is a construction with smaller dimensions allow given voltage to be held.
the wall in the isolation area at least one Recess or a recess, such, so Shaped and arranged that every projection of the switch axis on the wall cuts at least one such recess, one reaches first an extension of the isolation distance with the same dimensions, so an extension of a shortest, the non-conductive material of the wall in the insulation area not leaving connection between two poles of the corresponding circuit breaker. It is important to take into account that this material has a more critical influence on the isolation capability of the circuit breaker has as a switching chamber filling, usually gaseous Extinguishing medium, reinforced by the possibility of Deposition of burned material. Another advantage of the proposed Switching chamber can be seen in that through the recesses in the wall of the switching chamber now less burned material can settle on this wall.
the switching chamber at least in the isolation area a cylindrical shape.
the switching pieces in the switch axis or arranged symmetrically to the switch axis result thereby optimally minimized dimensions for a given minimum distance of the wall of the switching chamber in the isolation area to live parts of the corresponding circuit breaker.
the wall in the isolation area at least two, better yet has more than two such recesses.
a reasonable one Production costs are calculated if not more than twelve such recesses are provided.
the invention is the wall between five and eight have such recesses.
the single recess is elongated and preferably a ratio of length to width of between 4: 1 and 30: 1 has.
a slot-shaped recess can in particular easily be shaped so that two opposite Edges of the recess run parallel.
the slots are more than 20 °, better for a larger effect at least 30 °, opposite the switch axis or a projection the switch axis on the wall at one by the corresponding slot defined location inclined perform. It is advantageous, at least two, better yet more than two such recesses parallel to each other to arrange, preferably equidistant, so that the recesses to form a thread-like structure.
a higher number slits makes it easier to extend the insulation section and a reduction for deposits more susceptible Surfaces avoiding too much loss of stability.
slot-shaped Recesses in the wall of the switching chamber also perpendicular be oriented to the switch axis, wherein the recesses then arranged in at least two rows, that is offset laterally need to be an extension of the shortest isolation route to force in the wall.
Switching chambers according to the invention can be compared with corresponding ones Switch chambers of the prior art with lower Dimensions are executed.
the exact dimensions will be depending on the voltage to be bridged and after expected amperages in switching operations, at appropriate embodiments of the invention for uses, where the benefits mentioned are particularly pronounced are, the isolation range is a length of between 100 mm and 250 mm, especially when used in such Switches designed for a rated voltage of between 72.5 kV and 550 kV are designed.
the switching chamber is preferably at least in the isolation area with a diameter between 150 mm and 300 mm, to the lowest possible Dimensions of the switching chamber and the corresponding Switch with as large a distance as possible from the wall of the Switch chamber to connect to a switching arc.
the Recesses can have a largest at corresponding switches Expansion, in slit-like recesses so a length, from between 50 mm and 300 mm to have the largest possible Save space and minimize the loss of stability for the switching chamber the largest possible extension to effect the isolation route.
the switching chamber, in the isolation area of a possible good insulating material can be made there e.g. consist of cast resin or a fiber-reinforced cast resin, a material with which recesses are particularly good while avoiding frayed edges.
suitable fiber materials are added to industrial products such as Trevira or Kevlar in question.
the wall the switching chamber in the isolation area Preferably is for the wall the switching chamber in the isolation area to ensure a sufficiently high stability with the lowest possible cost of materials provide a wall thickness of between 4 mm and 15 mm.
a switching chamber according to the invention is particularly well suited for a circuit breaker using a gas as an extinguishing agent, in any case, the extinguishing chamber no liquid must hold in a way that with recesses in the wall the switching chamber would not be compatible.
a circuit breaker for high voltage installations with a switching chamber of the type described is a pin-like Switching piece slidably arranged in the switch axis, with the circuit breaker closed, from the quenching chamber is surrounded and in a ring or tulip contact as Rated current contact comes to lie, preferably an additional, on the switch axis lying arcing contact is to be provided on the a switching arc to protect the can skip corresponding rated current contact.
FIG. 1 therefore, a detail of a switching chamber of FIG imaged essential cylindrical shape.
the switching chamber has a cylindrical centerpiece 1, which has an isolation area forms the switching chamber. At two ends 2 this Center piece 1, which is made of a Trevira casting resin, closes in each case a metallic continuation piece. 3 on, which includes the corresponding end 2 of the center piece 1.
the middle piece 1 forms a wall of the insulation in the area Switching chamber, which has a wall thickness of 5 mm there.
These Wall has six slits shaped in the isolation area Recesses 4, opposite to a symmetry axis of the Switching chamber defined switch axis 5 inclined by about 30 ° are arranged.
These recesses 4 have a length of about 151 mm and a width of about 25 mm.
the isolation area the switching chamber has a contrast through the centerpiece 1 bridged and as the shortest distance between the metallic continuation pieces 3 defined length of 200 mm at a diameter of the switching chamber in the isolation area of 240 mm.
the recesses 6 are equidistant parallel arranged side by side, making them a thread-like Structure and each projection of the switch axis 5 on the wall formed by the middle piece 1 at least one of Recesses 4 intersects. This results in a prolonged Insulation route, so an extended shortest connection between the continuation pieces 3 within the wall of the insulating center piece 1, and a reduction of a formed by this wall surface at which Abbrandteilchen could deposit as a result of a switching arc.
FIG. 2 The switching chamber or quenching chamber described is in FIG. 2 again shown in perspective, wherein identical features again with the same reference numerals are provided.
This switching chamber is for installation in a Circuit breaker for a high voltage system with a Nominal voltage of 245 kV provided, a gas as extinguishing agent used.
a pin-like contact of this circuit breaker then comes in this not specially marked Switch axis 5 to lie, along which he slidably is designed so that he closed switch surrounded by the illustrated switching chamber.
a tulip contact, the said contact piece when closed Includes circuit breaker, which serves as a rated current contact and arranged in the middle of an additional arcing contact is then finds its place at one end of the Switching chamber.
FIG. 3 Another embodiment of a switching chamber according to the invention is shown in Figure 3, with recurring features again are marked with the same reference numerals.
the recesses 4, which run here again as slots are, with an orientation perpendicular to the switch axis 5 orientation arranged. Because the recesses are in two rows and staggered, is again ensured that any projection of the switch axis 5 on the wall of the Center piece 1 cuts at least one of the recesses 4, the recesses 4 so an extended isolation distance have as a consequence.
