Definitions

  • the invention relates to an embedded pole part and method of manufacture the same, with vacuum interrupter which is embedded or assembled in an expoxy resin or thermoplastic housing, with a fixed contact and a movable contact, wherein the fixed contact is electrically and mechnically fixed to an upper electrical terminal, according to the preamble of claim 1 and 8.
  • the vacuum interrupter is embedded inside a pole housing and inside epoxy resin or a thermoplastic material. This can be done by a hot mould or injection process. Alternatively the vacuum interrupter can also be introduced in a ready premanufactured housing, which is then called assembled pole part. The vacuum interrupter inside the embedded housing is stiff embedded in the housing.
  • the vacuum interrupter is covered with a damping layer between the interrupter surface and the epoxy housing.
  • the damping layer is made of elastic and/or at least compressible or at least partly compressible material.
  • the damping layer material of the terminal is polyurethane. This material is strong and with high mechanical and thermal resistance and can be treated in case of a following hot resin or thermoplastic process by remaining its mechnical characteristics.
  • a further material is that the damping layer material of the terminal is silicone. This material is strong and with high mechanical and thermal resistance and can be treated in case of a following hot resin or thermoplastic process by remaining its mechnical characteristics.
  • damping layer material of the terminal is rubber.
  • damping layer material of the terminal is polysiloxane.
  • the damping layer material of the terminal is a mixture of polyurethane and/or rubber and/or polysiloxane, and/or a multilayercompound with at least two of the aforesaid materials or material combinations.
  • the damping layer material can itself be a material mixture, or a layerwise compound construction itself.
  • the material layer has a bubble structure, and/or particals inside like hollow glass bubbles, and/or hard particles inside which provides a nonlinear characteristic the damping effect is adjustable.
  • the damping layer extends in the upper region in direct contact with the inner surface of the housing, and extends in the region towards the vacuum interrupter closely to next positioned cap or the metal cap of the vacuum interrupter. That means, that the damping layer is in direct contact with the vacuum interrupter at one side and with the inner wall of the housing around this terminal at the other sides.
  • the basical idea of the invention is, that additionally the upper terminal or the terminal according to the fixed contact will be covered by an elastic and/or at least partly compressible damping layer, before the predesigned assembly group will be introduced into the housing or covered by the housing by hot epoxy or thermoplastic process.
  • this additional special damping layer localized at the fixed contact terminal can be easily integrated into the manufacture process of the pole part and result in a final high performance pole part with bouncing reduction.
  • Figure 1 shows in a cross sectional view through the pole part.
  • the vacuum interrupter can optionally be introduced into the housing also with a damping layer between the vacuum interupter surface and the housing inside wall.
  • the fixed contact of the vacuum interrupter is located in the upper region.
  • the upper contact is mechanically and electrically connected with the upper terminal.
  • the upper terminal is covered at least on its surface region which is located inside the housing with the aforesaid damping layer between the terminal surface and the housing.
  • the damping material can be taken from polyurethane or silicone.
  • the damping material has to be applied in the way that the micromovement can be achieved e.g. by the use of the layer on top of the vacuum interrupter lid and the upper contact terminal.
  • the application can also be applied on defined areas where the movement can be achieved as well. This leads to a reduced force generated out of the Impulse be applying the equation dl / dt and reduced in addition the bouncing duration between the both contacts.
  • the vacuum interrupter can be embedded in epoxy material with and without a compensation layer.
  • the insulation material for the pole part can be epoxy, thermoplastic, BMC or other insulation material.
  • the effect is the reduction of bounce duration at the pole part.
