Definitions
- the invention relates to a switch-disconnector according to the preamble of claim 1 and a switchgear with the load-break switch.
- a switch-disconnector of the type mentioned has two housing sections, of which a housing section receives the drive.
- This drive comprises a driven by means of a drive shaft pivoting lever, at the free end of a rod-like contact carrier is articulated under the intermediary of a connecting lever.
- This rod-like contact carrier carries at its free end the movable contact piece, which forms a contact point with a fixed contact piece.
- the contact carrier is guided within an elongated cylindrical container and in a Ausschalte Stuttgart the movable contact piece separates from the fixed contact piece, wherein an arc is drawn, which is blown within the container and deleted. Between the two contact pieces there is an isolating distance in the off position with a length determined by a standard.
- the object of the invention is to provide a suitable field control within the separation distance.
- surrounding field control rings are mounted on the second housing section, of which the first is arranged in the region of the fixed contact piece and the second in the region of the switch-off position of the movable contact piece.
- the field control ring is connected to the potential of the fixed contact piece and the second field control ring connected to the potential of the movable contact piece in its off position via a respective connecting conductor.
- the second field control ring can be arranged within the separation path located between the two contact pieces, such that the movable contact piece is located immediately outside the area between the two field control rings.
- the field control rings can be glued to the outside of the second housing portion; but there is also the possibility that the first field control ring is formed at the free end of the outside of a pot, which pot is slipped over the free end of the first housing portion. At the bottom of the pot, the fixed contact piece is fixed and then on the outside of the bottom of the output conductor of the circuit breaker is connected.
- the invention also relates to an electrical switchgear, in which the switch-disconnector is installed, said switchgear being characterized in that the second housing portion of this surrounding field control rings are mounted, of which the first in the fixed contact piece and the second in the off position of the movable contact piece is arranged, and that the first field control ring are connected to the potential of the fixed contact piece and the second to the potential of the movable contact piece in its off position via a respective connecting conductor.
- FIG. 1 is a longitudinal sectional view of a load-break switch according to the invention
- Fig. 2 is a perspective view of the switch
- Fig. 3 is a perspective view of a detail of the housing.
- a switch-disconnector 10 comprises a housing 11 which has two housing sections 12, 13, of which the first housing section 12 contains a drive 14 and the second housing section 13 contains a contact point 15.
- the drive 14 has a pivotable drive lever 16 which cooperates positively with a provided with a 1 profile 17 drive shaft 18.
- the profile 17 is a groove profile; it could also be a polygonal profile or the like.
- the free end of the drive lever 16 is pivotally connected via a connecting lever 19 with a rod-like contact carrier 20, at the free end of a movable contact piece 21 is attached.
- the movable contact piece 21 cooperates with a stationary contact piece 22.
- the second housing portion is formed as an elongated, cylindrical container 23, which is provided at its one end 24 with a through hole 25 having a container bottom 26.
- the other, free end of the container 23 carries on its inner surface an internal thread 27.
- the first housing portion 12 is composed of two housing halves, of which only the housing half 28 is shown, because the second housing half is removed to provide an insight into the To allow first housing section. 2 shows the two housing halves 28, 28a.
- a semi-cylindrical collar extension 29 is formed, which together when the housing halves are assembled, form a cylindrical collar on the outer surface of an external thread 30 is formed on the the internal thread 27 of the container is screwed to hold the housing of the circuit breaker together.
- the container 23 is provided on its outer surface with field control rings 31, 32, of which the first field control ring 31 is associated with the fixed contact piece 22.
- This first field control ring 31 is integrally formed at the free end of a pot 33 of electrically conductive material by the free end is axially deformed and radially everted.
- the bottom 34 of the pot 33 is pulled axially outward and forms a collar-like axial projection 35, which comprises an extension 36 on the fixed contact piece 22 in an electrically conductive manner, so that the pot 33 is at the potential at which the fixed contact piece 22 lies.
- the second field control ring 32 is a torus-shaped bent ring which is open on the inside, so that two edges 32 a and 32 b are formed, which rest on the outer surface of the container 23.
- the field control ring 32 is at a height at which the movable contact piece 21 is in the off state. More specifically, the movable contact piece 21 is located outside the region between the distally opposite plane of the field control rings outwardly contacting planes which are perpendicular to the longitudinal axis of the container 23.
- the field control ring 32 is connected via an invisible connecting conductor to the potential on which the movable contact piece is in the off state.
- the field control rings are in the on state at the same potential; in the off state of the field control ring 31 are at high voltage potential and the field control ring 32 at ground potential, whereby an electric field is generated between the field control rings, which generates a homogenization of the electrical load and possibly prevents discharges.
- the switch-disconnector is shown in its closed position. When an elimination occurs, the drive shaft 18 rotates and pivots the Aritriebshebel 16 in a clockwise direction, so that the contact carrier 20 and thus the movable contact piece 21 are moved away from the fixed contact piece. After extinguishing the arc, the field control rings act in the manner described above.
- the load-break switch 10 is inserted into a carrier of a switchgear, see also the German patent application DE 10 2005 009 207.1 has the housing on the outer surfaces of its housing halves 28,28a parallel to the longitudinal axis of the container 23 extending grooves 40, 41 which in cutouts (not shown) of the carrier are inserted, see also the above-mentioned patent application.
- the two housing halves held together on the one hand by the cut-outs and on the other hand by the first housing portion.
- Fig. 3 shows a detail on the housing 10 according to arrow III in a greatly enlarged view.
- two projections 50, 51 are integrally formed, wherein the one projection 51 is formed approximately radially on the container 23, whereas the other projection 50 has an L-shape, with a leg 52 which is at a small distance from the container outer surface to Projection 51 projects approximately tangentially in a plane which is perpendicular to the longitudinal axis of the container. Between the free end of the projection 50 and the projection 51, a distance A remains free.
- a third projection 53 is formed, whose width B, measured perpendicular to the parting plane between the housing halves, is greater than the distance A.
- the projection 53 jumps in the direction of the container longitudinal axis of the both housing halves before and engages in the area between the projections 50, 51, when the container is fixed to the housing halves.
- a recess 54 is provided behind the assembled state, as shown, the projection 50 engages.
- the assembly is done as follows: When the container is screwed on, it is rotated in the direction of arrow U about its axis. Shortly before the end position slides an inclined surface 55 of the projection 50 on the end face 56 which is directed to the container outer surface. In this case, the projection 50 deforms until the projection 53 bears against the projection 51. At this moment, the projection 50 snaps into the recess, so that the container is locked to the first housing portion.
