Definitions
- the invention relates to a coupling device for electrically connecting a first conductor to a second conductor having a first connection piece for connecting the first conductor and a second connection piece for connecting the second conductor, wherein the first connection piece via flexible connection means, via Gleitsch- or via roll connection means is connected to the second connector, so that a relative movement between the first conductor and the second conductor is made possible.
- the invention further relates to a solid-insulated switch pole with an electrically non-conductive insulating housing and arranged in the insulating housing interrupter, which extends between an input terminal and a stationary outgoing terminal, wherein an axially movable switching rod is provided for initiating a drive movement in the interrupter.
- Such a coupling device and such a solid-insulated switch pole are already known for example from DE 19 71 21 82 Al.
- the coupling device shown there has as a first connection piece on a clamping part which is fixedly connected to an axially movable switching rod as the first conductor.
- the second connection piece is arranged stationarily in an insulating housing consisting of casting resin in which the switching rod is guided in an axially movable manner.
- the shift rod is rigidly connected to a moving contact of a vacuum interrupter, which is firmly embedded in the insulating material.
- the coupling device has a flexible metallic conductor strip, which is connected on both sides with a respective connecting piece. Since there are high current transfer resistances, in particular at the contact points of the conductor strip, a relatively high heat development which depends on the size of the rated current occurs at these points. In order to prevent damage to the switch pole, the current-related heating of the switch pole should not exceed 65 - 75 degrees Kelvin. Due to the resulting continuous current carrying capacity of the coupling device, the maximum permissible rated current of the switch pole is limited.
- the previously known coupling device has the disadvantage that the heat dissipation essentially takes place only via the heat conduction of the flexible current band, which dissipates the heat arising at the first connection piece to the second connection piece.
- the second connector is thermally conductively connected to outside of the insulating housing arranged conductors so that the heat can be discharged in this way to the outside atmosphere.
- the object of the invention is to provide a coupling device and a solid-state switch pole of the type mentioned above, which have an improved continuous current carrying capacity with constant heating.
- the invention solves this problem, starting from the coupling device mentioned above in that a cooling unit is provided for cooling the coupling device.
- the cooling no longer takes place, as in the prior art, solely via the heat conduction of the connecting means.
- the inventively provided Cooling unit causes additional local cooling of the coupling device, whereby the heating of the coupling device is significantly reduced. In this way, it is possible within the scope of the invention to carry higher rated currents through the coupling device, without leaving the range of permissible temperature increase.
- the cooling unit according to the invention can be configured as desired.
- the cooling unit may have water cooling.
- Essential within the scope of the invention is merely that the cooling unit for the purpose of cooling with one or more of the remaining components of the coupling device is thermally conductively connected.
- the cooling unit has a heat sink with cooling fins. Through the cooling fins, the heat exchange surface of
- the arrangement of the heat sink is arbitrary.
- the heat sink is thermally conductively connected to the first connection piece.
- Such a variant of the invention is particularly useful when the largest heat development takes place at the first connector.
- the flexible connection means have at least one flexible one
- a conductor band provides a cost-effective and less maintenance-prone connecting means between the Connectors, however, at higher voltages in the range of about 100 KV field distribution problems may occur.
- a first contact surface are each
- Conductor strip with the first connector and a second contact surface with the second connector each at least twice as large as the cross-sectional area of the conductor strip.
- the heat transfer surfaces between the conductor strip and the connecting pieces are increased.
- high current transfer losses with increased heat development occur in particular at the transition surfaces.
- Increasing the transition surfaces leads to a reduction of the current transition densities and thus to a reduction of the heat development at the junctions between the conductor strip and the connection piece.
- Each conductor strip is therefore not only soldered, for example, bluntly with its end face to the respective connection piece, but optionally has, in addition to the end face on a side surface, whereby the respective connector is contacted. In this case, a step-shaped cutout is provided in the connection piece.
- each conductor strip has a flexible bending section, the length of which in relation to its cross-sectional area is smaller than 0.1 mm "1. According to this development, the heat development in the conductor strip is optimized, since with such a ratio the area-related Current in the conductor strip and thus the heating in this is reduced.
- the first connection piece is a clamping part for clamping to an axially movable switching rod.
- the second connecting piece has a passage opening through which a switching rod can pass freely.
- a shift rod can be clamped to the first connector, wherein the second connector is embedded, for example, in the sheath of a solid-insulated switch pole.
- the object of the invention is also achieved by a solid-insulated switch pole of the type mentioned, which has a coupling device according to the invention, which connects the shift rod and the outgoing terminal electrically.
- the interrupter is embedded in the insulating housing, which has a venting channel cooperating with the cooling unit.
- vent channel is expediently arranged with its inlet opening above the cooling unit during operation of the switch pole and extends straight upwards.
- FIG. 2 shows a perspective view of the rear side of the coupling device according to FIG. 1,
- Figure 3 is a perspective plan view of the top of the coupling device according to Figure 1 and
- Figure 4 show a perspective plan view of the underside of the coupling device according to Figure 1 without cooling unit.
- FIG. 1 shows a perspective view of an exemplary embodiment of the invention
- Coupling device 1 which has a clamping part 2 as the first connection piece as well as a stationary connection piece 3 as a second connection piece.
- the two connecting pieces 2 and 3 are electrically connected to one another via two flexible current bands 4.
- the clamping part 2 has a clamping recess 5, which is provided for receiving a switching rod of a solid-insulated switch pole.
- the clamping part 2 has two sections 6 and 7, whose distance can be varied by clamping screws 8. By means of the clamping screws 8, the clamping part 2 can therefore be firmly clamped to the shift rod.
- a heat sink 9 with cooling fins 10 can be seen on the clamping part, the heat is conductively connected to the clamping part 2 and in this way increases the heat exchange surface of the coupling device 1.
- FIG. 2 shows the coupling device 1 according to FIG. 1 from the rear.
- the clamping part 2 has at its sections 6 and 7 in each case a step-shaped cutout 11, on which the Stromband 4 is soldered with its front end portion fixed to the clamping part 2.
- the step-shaped cutout 11 allows soldering both on the end face 12 of each current band 4 and on the flat side 13 in the end-side end region, whereby the
- Transition surfaces increased and the heat generation is reduced by current transfer are increased and the heat generation is reduced by current transfer.
- a conventional screw connection 14 is provided, the current bands 4 resting flat on the stationary connection piece 3, so that here too large exchange surfaces are provided for reducing the heat.
- FIG 3 shows the coupling device according to Figure 1 in a plan view of the top.
- the cooling fins 10 have a different depth, so that a cylindrical outer contour or envelope and thus the installation in hollow cylindrical space, such as in tubular insulating material, is possible.
- FIG. 4 shows the coupling device 1 from below, wherein the cooling body 9 has been removed from the clamping part 2. It can be seen that the connection between the heat sink 9 and clamping part 2 via a screw connection. In this view, it can also be seen that the stationary connection piece 3 for the free passage of a shift rod has a passage opening 15 which has a larger inner diameter than the shift rod.
