Definitions
- the invention relates to a method for producing a solid-insulated switch pole.
- Such a method is for example from the
- WO 2004/038748 AI known and comprises the steps:
- the pole housing normally consists of a long-term stable plastic, for example of a duroplastic (for example epoxy resin) or a thermoplastic (for example polyamide) or a composite material or the like.
- the vacuum switch tube as a switching element of a commonly more ⁇ phase formed the circuit breaker, such as a medium voltage circuit breaker disposed in the Polschalengephaseuse for dielectric insulation, wherein the Polscha ⁇ lengephaseuse terminals, via which a is kuumschaltrschreibe means of Va led to switching power.
- the elasti ⁇ cal cushioning layer also has thus insulate the connections with ⁇ the task, and therefore must have a suffi ⁇ sponding dielectric strength.
- the object of the present invention is to specify a method for producing a solid-state switch pole, which can be implemented simply and inexpensively.
- the pole shell housing is initially formed completely with an elastic layer connected to the pole shell housing in the interior, so that the pole shell housing with the cohesively connected elastic layer as
- the Polschalenge ⁇ housing is formed with the elastic layer as an integral part of the pole shell.
- Cohesive in the sense of the present invention also includes a very good adhesion, for example of compatible materials.
- the step of forming the pole shell with the layer which is materially connected to the pole shell comprises the steps of:
- the elastic layer is first formed as a separate, separate component, which is then surrounded in the next step with the pole shell.
- the step of forming the Polschalengekoruses with the integrally connected with the elastic pole shells ⁇ housing layer comprises the steps of:
- Pole housing can be done differently, for example by an injection molding process, or particularly advantageous by a two-component injection molding process in which in the first process step, the elastic layer and in the second process step the pole shell of a long-term stable, solid plastic is sprayed onto the elastic layer, or Conversely, in the first step, the pole shell is made and in the second step, the elastic layer is injected into the pole shell.
- the cohesive introduction of the elastic layer in the pole shell can be done differently, for example by spraying or by gluing the elastic layer in the pole shell, which is formed for example of epoxy resin or polyamide.
- Suitable materials for the elastic layer are, for example, thermoplastic elastomers, silicone, or EPDM, whereby, if appropriate, by a suitable chemical or physical pre-treatment specific ⁇ the Kunststoffsfestig- ness between the elastic layer and the Polschalenge ⁇ housing can be further improved.
- the cohesively connected to the pole shell housing elas ⁇ tical layer can enclose the vacuum interrupter, or partially surround a housing wall portion of the vacuum interrupter.
- a solid-insulated switch pole is likewise known from WO 2004/038748 A1 and comprises a pole shell with a first connection, a second connection, a
- Vacuum interrupter and a arranged between the pole shell and vacuum interrupter elastic layer.
- Object of the present invention is to develop a solid-insulated switch pole of the type described above, which is simple and inexpensive to produce.
- the figure shows a solid-insulated switch pole 1, which has a pole shell 2, which is preferably formed in a casting process from an epoxy resin or a similar, a solid pole shell housing forming material ge ⁇ .
- a first connection 3 and a second connection 4 are provided on the solid-insulated switch pole 1, which are provided for connection to current-carrying parts of a switchgear, in which a switch with one or more such solid-state switch poles 1 is arranged ,
- a vacuum interrupter 5 is arranged, which ei ⁇ nen figuratively not shown fixed contact and a fictitiously also not shown moving contact within a housing 6, wherein the fixed contact via a fixed contact terminal pin 7, which extends through a first metallic housing part 8 extends therethrough, with the second terminal 4 and the moving contact via a BewegWalletan- connecting bolt 9, which extends through a second metallic
- Housing part 10 extends therethrough, is electrically conductively connected to the first terminal 3.
- the BewegCountan gleich- bolt 9 is mechanically coupled via an insulating shift rod 11 with a drive also figuratively also not shown for initiating a drive movement to
- Ceramic cylinder is formed, completely enclosed by an elastic layer 14 in the embodiment.
- the pole housing 2 has undercuts 15, 16 in such a way that the pole shell housing 2 has a smaller inner diameter outside the region of the elastic layer 14 than in the region of the elastic layer. This is particularly advantageous when first the elastic layer 14 is thoroughlybil ⁇ det as a molded part and then the pole shell is arranged around the molded part of the elastic layer by molding or encapsulation.
- the undercuts 15, 16 are but optional and not essential.
- the elastic layer 14 is materially connected to the pole shell 2 of the solid-insulated switch pole 1, for example by introducing the elastic layer 14 in the pole shell 2 or by attaching the pole shell 2 on the prefabricated elastic layer 14, so that in particular a mounting of the vacuum interrupter 5 in the versehe with the elastic layer 14 nen ⁇ pole shell 2 is possible.
- the elastic layer 14 ensures a compensation of expansion fluctuations, which result due to the different Temperaturaus ⁇ expansion coefficient of the vacuum interrupter 5 and in particular the housing 6 of the vacuum interrupter 5 and the Polschalen ⁇ housing 2, and the necessary dielectric Isolie ⁇ tion.
- thermoplastic elastomers silicones, Polyu ⁇ rethane or EPDM are possible, for example, one wherein the elastic layer can be inserted 14, for example by means of an injection molding process, by Be ⁇ spray or by gluing in Polschalengephaseuse. 2 Reference sign list
