Definitions
- the present invention relates to a switching chamber isolation device, and more particularly to a switching chamber isolation device for a circuit breaker having improved heat dissipation capability.
- Circuit breakers for switching high voltages or high currents usually have elaborately designed contact poles, which can be moved relative to each other to make an on or off. Due to the high voltages or currents occurring, it is generally necessary to position the two switch contact poles in a defined manner relative to one another so that the corresponding contact surface can be contacted or disconnected in a predetermined manner.
- a switching chamber insulation arrangement is provided which positions the two switching contact poles in such a way that a geometrically predetermined opening and closing of the contact surfaces of the switch contact poles is ensured to one another.
- Such a switching chamber insulation arrangement must not only ensure a mechanical stabilization of the two switch contacts to each other, but also have a dielectric strength, which withstands the occurring voltages, in particular in the opened state of the switch contacts.
- hitherto substantially closed pipe arrangements have been used, on which the two switch contact poles are fixed, so that moving parts of the switch contact poles can move toward one another in a defined manner.
- such pipe arrangements have a spatial foreclosure of the contact surfaces of the Switch contact poles result, so that an occurring heat generation can not be reliably dissipated at the contacts of the switch contact poles in certain operating conditions.
- a switching chamber isolation device with a switching chamber isolation arrangement that enables improved heat dissipation in the area of the switch contact poles.
- the object of the present invention is achieved by a switching chamber insulation arrangement or a circuit breaker according to the subject of the independent claims, wherein exemplary embodiments are embodied in the dependent claims.
- a switching chamber isolation assembly comprising a strut assembly having a plurality of struts, each strut having a first leg region, a second foot region, and a midregion located between the first root region and the second root region, the struts being about a longitudinal axis of extension Struts arrangement along a circumference are arranged, wherein the strut arrangement has a first mechanical coupling portion on the side of the first foot portions for coupling to a first pole of a circuit breaker and a second mechanical coupling portion on the side of the second foot portions for coupling to a second pole of a circuit breaker.
- first pole' or 'first contact pole' and 'second pole' or 'second contact pole' of a circuit breaker does not mean two poles of different electrical phases, but rather a first contact part and a second contact part of a single circuit breaker, wherein the first contact part and the second contact part are electrically separable from each other.
- the region of the contacting of the two switch contacts is no longer spatially sealed off from the remaining volume of the switch, but communicates with the remaining volume of the switch.
- gas-insulated circuit breakers it is possible for gas-insulated circuit breakers that a gas exchange takes place in the region of the switch contact poles with the remaining gas volume, whereby improved heat dissipation in the region of the contact points of the switch contact poles can be achieved.
- the strut arrangement allows sufficient positioning and force absorption, so that a reliable opening and closing of the contact of the switch contact poles is ensured.
- a corresponding mechanical coupling to corresponding regions of the switch contact poles can be achieved via the mechanical coupling regions of the strut arrangement.
- the struts have an elongate cross-section in the middle region.
- An elongated cross-section is understood to be an elongation substantially orthogonal in the direction of a circumference, ie, azimuthal to a longitudinal axis of the struts or the strut arrangement. Elongated may be, inter alia, but not exclusively, oval, elliptical or kidney-shaped.
- the outer housing is formed as an insulator.
- the outer housing is metallic or at least metal-encapsulated.
- the respective first foot regions or the respective second foot regions are offset from the corresponding central regions in a radial direction of the switching chamber insulation arrangement by a distance with respect to the longitudinal extension axis.
- Cranked means that the two central axes, d. H. the central axes of the foot areas and the central axes of the central areas are shifted from each other.
- the center regions can be located radially further outside than the foot regions. In this way it can be achieved that the foot portions can be attached closer to the switch contact poles, but a sufficient dielectric distance between the contact surfaces or live parts of the switch contact poles is ensured to the central regions. This is particularly relevant if the foot areas of the switching chamber insulation arrangement are covered by field-controlling elements. Thus, a compact design of a circuit breaker with a corresponding switching chamber isolation arrangement can be ensured.
- the first foot region of a respective strut is shifted relative to the associated second foot region in this strut along the circumference, so that the struts are inclined with respect to the longitudinal extension axis.
- the struts can be shaped similarly to a helix section in order to ensure the sufficient distance to the switch poles.
- the effective length of the strut lengthens with the same distance the two fastening planes, which extend orthogonally with respect to the longitudinal extension direction of the switching chamber insulation arrangement and in which in each case the first and the second foot areas can lie.
- an elongated creepage path along the surface of the respective strut results, so that such a strut arrangement has a higher surface discharge resistance compared to a strut arrangement with struts which extend parallel to a longitudinal extension direction.
- the strut arrangement thereby has at least three struts.
- the strut assembly at least four struts, wherein the struts are alternately inclined in opposite directions to the longitudinal direction, such that a stiffening results in the circumferential direction about the longitudinal axis.
- a field control electrode is embedded in the first foot regions or the second foot regions, wherein a force receiving device is arranged within the field control electrode.
- Such a force-absorbing device may for example be a thread or a bolt, but also a bayonet connection or a clamping connection.
- the field control electrode can bring about a field-optimized geometry so that the field elevations can be kept substantially below a critical range.
- a field-optimized regarding the outer contour metal part may be provided in the interior, for example, the force receiving device is in the form of a thread or other attachment, so that the force receiving device and the field control electrode are integrally formed.
- the elements of the field control electrode can be made of metal as well as of another potential-carrying material, such as a plastic, the potential-carrying additive, such as carbon or graphite is mixed.
- the first foot portions of the struts are each formed integrally with a first carrier ring and the second foot portions are each formed integrally with a second carrier ring.
- the carrier rings can extend along a circumference, which essentially corresponds to the outer dimensions of the switch contact poles.
- a substantially integral switching chamber isolation arrangement may be provided can be easily attached to the corresponding switch contact poles, without having to make a separate alignment of the individual struts to each other.
- a corresponding heat dissipation or a gas exchange in a gas-insulated circuit breaker is maintained by the strut arrangement.
- the cranking can take place both in the region of the struts, ie between the foot region and middle part, as well as in the region of the carrier rings.
- the strut arrangement comprises a polymer resin and has a metal-oxide-filled polymer resin in at least one section of an electrical insulating section.
- Polymer resins ensure reliable dielectric strength and, at the same time, mechanical stability.
- a corresponding metal oxide filling can bring about an increase in the mechanical stability, as well as represent an improved thermal property.
- the polymer resins for example, but not limited to, an epoxy resin, a polyurethane resin or a phenol resin may be used.
- So metal oxide can be used for example alumina Al2O3.
- titanium dioxide or magnesium oxide can also be used.
- a suitable combination may consist, for example, of an aluminum oxide-filled epoxy resin, with aluminum oxide having a certain resistance to SF6 and SF4, which occur in particular in gas-insulated circuit breakers.
- the strut assembly may have a homogeneous structure, for example, be a homogeneous potting compound, or machined from a homogeneous material.
- a homogeneous structure for example, be a homogeneous potting compound, or machined from a homogeneous material.
- longitudinal structures such as fiber inserts, in particular if they allow a discharge or partial discharge problem to be expected.
- the middle region of at least one strut has a shell which is radially outer with respect to the respective strut and a filling which is radially inward with respect to the respective strut.
- the outer shell may completely comprise the respective strut on the outside or may also be designed only as a half shell.
- a shell can absorb corresponding tensile forces, in particular when using corresponding tensile-stable materials, while an internal filling can absorb compressive forces.
- a shell can also provide mechanical protection for the internal filling. In this way, a particularly tensile and compressive force becomes stable, i. also provides a flexible strut arrangement for a switching chamber isolation arrangement.
- the circumference is circular and / or the switching chamber insulation arrangement can be installed in a single-phase encapsulated circuit breaker.
- a circular circumference allows a simplified assembly of the switching chamber insulation arrangement or the circuit breaker, since a corresponding radial alignment does not have to be considered.
- At least part of the strut arrangement is coated, in particular with a diffusion barrier.
- Such a diffusion barrier may be, for example, a titanium dioxide coating or an epoxy coating. In this way it can be prevented, in particular, that aggressive decomposition products that can occur in a gas-insulated circuit breaker due to the action of arcing attack or even destroy the structure of the strut arrangement or the switching chamber insulation arrangement.
- the middle part of the strut may also have a supporting and stabilizing core insert, such as a composite tube, a composite strip or a rod, whereby the filling or strut can be cast around the corresponding tube, strip or rod.
- the middle part of the strut may also have a fiber reinforcement insert, in particular the form that no discharge or partial discharge operations are to be feared.
- a circuit breaker is provided with a switching chamber isolation arrangement according to the invention, a first switch contact pole and a second switch contact pole, wherein the circuit breaker is a single-phase encapsulated power switch.
- the switching chamber insulation arrangement and the first and second switch contact pole are connected to one another in such a way that the first or second switch contact pole are aligned and defined in a defined manner with respect to one another.
- the power switch comprises a first field control cover disposed at a nominal contact, wherein the first field cover is connected to the first switch contact pole and / or the second switch contact potential, and wherein the first mechanical coupling region is at the first switch contact pole or the second switch contact pole under the first field control cover is mechanically connected to the first switch contact pole.
- FIG. 1 shows a switching chamber insulation assembly with a strut assembly 100, which consists in the embodiment shown here of four struts 10, 20, 30, 40, in longitudinal section.
- each of the struts has a central region 12, 22 and corresponding first foot regions 11, 21 as well as second foot regions 13, 23
- Switching chamber insulation arrangement 100 shown here has a first coupling region 101 and a second coupling region 103.
- the struts are arranged substantially parallel to a longitudinal axis L, wherein the individual struts or their bases are arranged along a circumference U. The distance of the struts along the circumference is uniform in the embodiment shown here, but may also be uneven as needed.
- switching chamber isolation assembly comprises struts with a crank, with reference to FIG. 2 will be described below.
- FIG. 2 shows a detailed view of a foot portion 11 of a strut 10 and a central region 12 of a strut.
- the central axis M F of the foot region 11 is shifted relative to the central axis M M of the central region 12 by a distance d, wherein in the embodiment shown here the two central axes M F and M M run parallel.
- an example circular cross-section can be selected, while in an intermediate region 12 an elongated, for example an oval or kidney-shaped cross section can be selected.
- the round cross-section is favorable for attachment, while the elongated cross-section in the central region allows a space-optimized strut arrangement in this central region.
- FIG. 3 shows a strut assembly with three struts 10, 20, 30, which are arranged uniformly along a circumference U in this embodiment.
- struts shown here are similar, as in FIG. 1 , cranked, such that a central region of the struts is located radially farther outside than a corresponding base region.
- FIG. 4 shows an analogous arrangement with three struts 10, 20, 30, which are also regularly arranged along a circumference U, but the struts are provided without cranking, which of course simplifies the production of the struts as such.
- Such an arrangement can be used in particular when it does not depend on a space-saving arrangement.
- the struts may be circular cylindrical, but may also have a cylindrical shape with an elongated cross-section or a circular-cylindrical foot region and an elongated central region.
- FIG. 5 also shows a strut assembly with three struts 10, 20, 30, wherein, however, the corresponding foot portions 11, 21 relative to the associated foot portions 13, 23 are displaced along the circumference.

In this way, however, arises a relatively torsionally stable strut arrangement, since in a torsional load, the struts are alternately charged to train and pressure.
- FIG. 9 shows an arrangement with a total of five struts 10, 20, 30, 40, 50, wherein in the in FIG. 9 As shown, the foot points are in turn distributed uniformly along the circumference U. In this way, for example, the struts can be made thinner, and a redundant system can be provided with respect to a fracture fracture. It should be understood that, of course, more than five struts can be used.
- FIG. 10 shows a detailed view of a foot portion of a strut 10, wherein the foot portion 11 is offset from the central region 12.

- the central region 12 can also be provided with a mechanical reinforcement 99, which can be, for example, a fiber reinforcement insert or a composite material tube or a strut or the like. It should be understood that in a strut not necessarily the reinforcement 99 and the field control assembly 14 must be provided simultaneously, but also only one of the two arrangements can be provided. In addition, it should be understood that the field control device 14 or the reinforcement assembly 99 can also be used with non-cranked struts.
- the reinforcement assembly may also be connected to the field control assemblies on either side of the strut to ensure positioning of the foot portions, for example, before and during a potting process.
- the strut may additionally be provided with a coating 98 which, for example, represents a diffusion barrier. The coating can cover both the surface of the strut entirely, as well as be provided only in areas of the struts or the strut assembly.
- FIG. 11 shows an exemplary embodiment of a switching chamber isolation arrangement, in which the struts each integral with a first Carrier ring 60 and a second carrier ring 70 are configured.
- the coupling region 101 can be designed in the region of the first carrier ring 60, while the second coupling region 103 can be configured in the region of the second carrier ring 70.
- the foot portions 11, 21 and 13, 23 of the struts may terminate in the corresponding support ring 60, 70 and be formed integrally with the corresponding central regions 12, 22.
- the cross section of the struts may also be round or elongated, as well as the struts may be oblique and not necessarily be configured parallel to the longitudinal direction of the switching chamber insulation arrangement.
- FIG. 12 shows a sectional view through a portion of a gas-insulated circuit breaker.
- the circuit breaker in this case has a housing 111 which encloses a gas space. Within the gas space are the two contact poles 1 and 2 of the circuit breaker.
- the first contact pole 1 has a movable part 1a, which is axially movable along a longitudinal extension direction L.
- the rated current contacts 8 first open, so that the current commutates to the arcing contact 8a. In a further axial apart then opens the arcing contact 8a.
- the struts 10, 20 each have central regions 12, 22, whose center axes are displaced radially outward relative to the central axes of the foot points 11, 21 and 13, 23.
- the bases are attached to the respective contact poles 1, 2 of the circuit breaker, here for example by a Screwing.
- the field increase by, for example, the screw edges can be compensated for by covering the base point regions 11, 21, 13, 23 by corresponding field control elements 4, 6, which are correspondingly conductively connected via a conductive connection 5 or 7 to the corresponding contact poles 1, 2. In this way, impermissible field increases, in particular with respect to the outer housing 102, can be substantially avoided.
- FIG. 13 shows a sectional view through the switching chamber insulation assembly with the associated contacts along a parting line, which in FIG. 12 is drawn accordingly.
- the struts 10, 20 corresponding central portions 12, 22 which are elongated.
- the foot areas 13, 23 are offset from the central areas and thus have a center which lies radially further inwards.
- the struts can be made in the embodiment shown here from a polymer resin.
- FIG. 14 shows a further embodiment of the invention, in which (analogous to FIG. 13 ) Middle portions 12, 22 of the struts 10, 20 displaced, ie cranked, are arranged.
- the central region 12, 22 can be provided, for example, with a shell 12b, 22b which lies radially on the outside. Radial outside means here with respect to the individual strut, but can also be understood with respect to the entire switching chamber insulation arrangement.
- the shell 12b, 22b for example, along the entire circumference of the central region of the strut may be arranged, but also designed as a half-shell, and in FIG. 14 is shown.
- the inner region, ie, radially inward, with respect to either the strut, but also within the switching chamber insulation assembly may be provided with a filler 12a, 22a. In this way, a particularly tensile and compressive force stable arrangement of the switching chamber isolation arrangement can be provided.
