Definitions
- the invention relates to a tulip contact piece for a high-voltage switching device according to the preamble of claim 1, and a contact arrangement according to the preamble of claim 2.
- Such a tulip contact piece is a mating contact piece or a fixed contact piece for the contact pin of an earthing switch; accordingly there is a possibility that when switching off or when switching on between the tulip contact piece and an arc is drawn on the mating contact piece.
- the tulip contact piece and the counter contact piece must have a coating be made of erosion-resistant material.
- contact fingers in tulip shape for such a switch are essentially intended for nominal current cutoffs.
- Another solution is there in providing a finger contact basket that mates with the mating contact piece in Connection is established and, and around it, a finger basket to arrange the power transmission to effect.
- the contact arrangement thus has two contact points; the one is used for nominal current transmission, and the other is an arc underneath broken. Wherever an arc occurs, erosion-resistant material must be provided and accordingly, the front ends of the fingers wear erosion-resistant material.
- a tulip contact piece of the aforementioned type is known from US 4,841,108 become.
- This contact piece belongs to a high-voltage circuit breaker; contact fingers are connected to a movable contact designed as a tube, which are delimited on both sides by axial slots; the free end of the contact fingers has an annular, inwardly projecting thickening that is rounded is, the transition between the contact fingers and the rounding is conical is formed with an acute angle. In comparison to the contact fingers is the radial one Thickness of the actual contact point is small.
- the object of the invention is to provide a tulip contact piece of the type mentioned create that it can also be used with simplified production, if blowing with extinguishing gas is not required.
- the invention accordingly consists in that an axially with slots the cylinder provided, which slots form the contact fingers between them, that adapted at the opposite end of the cylinder of the annulus slotted ring is formed, its cross-sectional shape together with the cylinder has the shape of a golf club that the free axial end of the ring has a radial
- Has annular surface on which a section of erosion-resistant material is attached is that the inner diameter of the tulip contact piece corresponding to the counter contact piece is smaller than the inner diameter of the section made of erosion-resistant Material that the inner surface of the ring facing the annulus Area with a cylindrical inner surface and an adjoining to Free end opening conical region, the axial end of the ring facing partial area limited by the section made of erosion-resistant material is that the surface area of the ring facing the circular ring is a conical surface forms, the cone angle is an obtuse angle and is open to the annulus and that the wall thickness of the cylinder between about 1/4 to 1/6 of the radial extent of the ring
- the mating contact piece then leaves the inner surface of the ring and finally separates from the section made of erosion-resistant material, so that the Arc on the tulip contact piece on the section attached to the front made of burn-resistant material with a base.
- the counter contact piece is accordingly also at the end facing the tulip contact piece with a section made of fire-resistant material. This also burns the other base on the mating contact piece on this erosion-resistant material.
- a contact arrangement is formed, which is a pin-shaped Has counter contact piece, which is formed according to subclaims 2 and 3 is.
- the counter-contact piece arrangement 20, 21 is formed from a contact piece carrier 22, to which the actual mating contact piece 23 is attached, which is enlarged in FIG. 4 is shown.
- the tulip contact piece 13 has a circular ring 24 which has an internal thread 25 with which the tulip contact piece is fixed on the projection 15 is.
- a cylinder 26 adjoins the circular ring 24, the cylinder 26 having radial Slots 27, 28 is provided so that there are between two slots 27 and 28th a resilient cylinder section 29 is located, a total of eight such resilient Cylinder sections are provided.
- the individual cylinder sections 29 then form the entire cylinder 26.
- On the cylinder 26 there is an adapted slot provided ring 30, which together with the cylinder 26 in cross section, that is in Cross-section in the axial direction, giving a golf club shape.
- FIG. 5 shows part of the ring 30 in an enlarged view.
- the outer contour 36 of the ring 30 is an arc of a circle.
- the circular ring 24 with the cylinder 13 and the ring 30 is made of copper, whereas the erosion-resistant material is a sintered alloy made of copper and tungsten.
- the switch shown in Fig. 6 serves as an earthing switch.
