Definitions
- the invention relates to the field of switch technology, in particular the high and medium voltage switch technology. It relates to a contact arrangement for a vacuum interrupter chamber according to the preamble of claim 1 and to a vacuum interrupter chamber and a. Switching device.
- Such a contact arrangement and such a vacuum switching chamber are known for example from the published patent application DE 1 97 05 1 58 and from the patent US 4,847,456.
- the outer contact pieces are electrically connected in parallel and spatially arranged closely adjacent to the inner contact pieces.
- One of the inner contacts is movably supported while the others Contact pieces are stationary.
- the outer contact pieces are designed as AMF contact pieces.
- a further increase in the switching capacity at comparable switch size is desirable.
- a high short-circuit breaking capacity is desirable.
- a contact arrangement for a vacuum switch is disclosed with a pair of slotted pot-shaped contact pieces, wherein the pot bottom of the inner pot-shaped contact piece is formed as a part of the pot bottom of the outer pot-shaped contact piece.
- the inner and outer contact pieces are (at their upper pot edges) spatially widely spaced from each other.
- a contact arrangement for a vacuum interrupter chamber is known in which slotted pipe sections are provided as inner contact pieces and outer contact pieces.
- the inner tubular contact piece is slotted so that thereby resilient contact tongues are formed. This is intended to create a plurality of separate mechanical contact points with a defined spring constant become.
- an additional contact piece is arranged within the inner resilient contact piece, which is provided for carrying operating currents and through which low contact resistance can be realized. When opening the switch, the additional contact piece is first lifted. As a result of the associated increase in resistance at the additional contact piece, the current then flows through the inner resilient contact piece. After lifting the inner resilient contact piece then forms an arc.
- CB l 145 451 a contact arrangement for a vacuum interrupter chamber is disclosed with three pairs of slotted pot-shaped contact pieces arranged one inside the other.
- the pairs of contact pieces should be designed so that when a contact separation of the two contact pieces of each of the three pairs of contact pieces ever an arc is ignited and then rotate these three arcs between the two contact pieces of each pair of contact pieces and respectively form a substantially cylindrical arc curtain.
- a contact arrangement and a vacuum interrupter chamber of the type mentioned which allow an increased switching capacity.
- Short-circuit current breaking capacity can be achieved at a high arc burning voltage.
- the contact arrangement should have a low resistance and can carry large currents.
- An inventive contact arrangement for a vacuum interrupter chamber has a pair of inner contacts formed as RMF contacts and a pair of outer contacts.
- the outer contact pieces are electrically connected in parallel to the inner contact pieces and spatially arranged closely adjacent to the inner contact pieces. At least one of the inner contact pieces is movably mounted.
- the outer contact pieces are designed as RMF contact pieces.
- the inner contact pieces are formed substantially disc-shaped. The inner and the outer contact pieces are arranged and formed such that a resulting in a Ausschaltvorgang between the inner contact pieces arc can commute completely or partially between the outer contact pieces.
- An RMF contact has the significant advantage over an AMF contact that the current path resistance of the vacuum interrupter chamber at a high contact pressure (up to several thousand Newtons) is at a lower level.
- the axial magnetic field of the AMF contact is generated by the flowing current, there is a large inductance;
- the axial magnetic field of the AMF contact is generated by permanent magnets 5, there are large eddy current losses.
- each of an inner and an outer contact piece ensures that an arc formed between the inner contact pieces forms an arc between the outer ones
- the two outer contact pieces can be arranged fixed or movable. Either both outer contacts are particularly advantageous fixed, or one is fixed, while the other is movable. In the latter case, the movement of the movable outer contact piece is advantageously coupled to the movement of the movable inner contact piece, advantageously by a rigid connection of the two movable contact pieces.
- each an inner and outer contact piece is arranged to be movable and they are rigidly connected to each other, advantageously the movable inner contact piece projects beyond the movable outer contact piece in the axial direction. It can also serve both the inner and the outer contacts as rated current contacts.
- Breaking capacity may have smaller dimensions.
- a switching device can of course be a vacuum switch.
- the switching device but also be a circuit breaker or a high-power switch and in particular a generator switch, wherein the switching device includes at least one vacuum interrupter chamber, which is typically part of a vacuum switch.
- Slots 26 are provided so that they form an RMF contact piece pair. In the case of a current flowing through the contact pieces 21, 22, therefore, a radially extending magnetic field is generated.
- the inner contact pieces 1 1, 1 2 are formed as RMF contact pieces and provided with slots, but which are not shown in Fig. 1.
- the substantially disc-shaped movable contact pieces 1 1 and 21 are attached to a movable contact stem 41.
- the fixed contact pieces 1 2 and 22 are fixed to a fixed contact stem 42.
- Fig. 2 are both outer contacts 21, 22 of the vacuum interrupter chamber 1 ' fixed contact pieces.
- the outer contact piece 22 is formed predominantly tubular, with a connection 28 to the lid 71 which serves as a contact carrier 28 at the same time. During a switching operation, the distance between the two outer contact pieces 21, 22 does not change from each other. Again, the inner contact pieces 1 1, 1 2 the
- the mass to be moved during a switching operation is lower in the case of a vacuum interrupter chamber 1 ' according to FIG. 2 than in the case of a vacuum interrupter chamber 1 according to FIG. 1.
- Fig. 3 shows a plan view of an inner contact piece 1 2 and an outer contact piece 22 along the in Figs. 1 and 2 designated III level. Concentric about the inner, provided with slots 1 6 contact piece 1 2, the outer contact piece 22 is arranged. Through the slots 1 6 creates a plurality of contact sockets 1 5 of the inner contact piece 1 2. Since the outer contact piece 22 is provided with the annular, non-slotted coating 24, the underlying slots in the contact piece 22 in Fig. 3 are not visible. LIST OF REFERENCE NUMBERS
