Definitions

  • the present invention relates generally to high voltage bushings and more particularly to insulation techniques for high voltage bushing for use in high environmental requirements.
  • An objective of the present invention is to propose a new concept of a bushing adapted to high environmental requirements, in particular to prevent oil pollution, and that enables additionally an easy and cost efficient manufacturing.
  • the present invention proposes notably a capacitive graded bushing for high electric voltage comprising an ester as impregnation agent within its capacitive graded core as disclosed by the object of the independent claim.
  • the present invention concerns therefore a capacitive graded bushing for high electric voltage comprising:
  • FIG. 1 A preferred embodiment of a capacitive graded bushing according to the invention is presented in Figure 1 , which shows a part of a high electric voltage capacitive graded bushing 1 for a transformer or a high voltage device.
  • the bushing 1 comprises an insulator 11 having a chamber 111 for receiving an electrical conductor 13 and insulating matter 12 that surrounds the electrical conductor 13.
  • the electrical conductor 13 can be a solid or rope conductor. According to a first preferred embodiment, the electrical conductor 13 might be placed within a tube 15. According to other embodiments, the electrical conductor might be a conductive tube.
  • the electrical conductor 13 comprises a first extremity 131 located at the top of the bushing 1 and configured for being electrically connected to a first device and a second extremity (not shown) configured for being connected to another device, for instance a transformer.
  • the electrical conductor 13 typically extends from the top of the bushing 1 to its bottom through the insulator chamber 111, clamping means and gaskets ensuring the different parts of the bushing 1 being hermetically held together.
  • the bushing 1 further comprises concentric conductive layers 121 (e.g. aluminum foils) which are isolated against another and serve as a built-in capacitor for equalizing and controlling the electrical stress on the insulation and maximizing the electrical field uniformity.
  • the insulating matter 12 suitable for high voltage fills then the space between successive concentric conductive layers 121.
  • the concentric conductive layers 121 arranged concentrically around the electrical conductor 13 and spaced apart by said insulating matter 12 form the capacitive graded core 16 of the bushing 1.
  • the capacitive graded core 16 is typically placed within the chamber 111 and preferentially surrounded by insulating matter, e.g. insulating liquid 2.
  • the insulating liquid is an ester liquid that preferentially fills a space between the capacitive graded core 16 and a wall of the insulator chamber 111.
  • the present invention proposes to use a dielectric insulation material impregnated with an ester liquid as insulating material placed between the successive conductive layers 121.
  • the insulator 11 might be surmounted by an expansion chamber 14 communicating with the chamber 111 of the insulator 11 in order to have the ester liquid 2 filling the chamber 111 and extending upwardly into the liquid expansion chamber 14.
  • the ester liquid may partly fill the expansion chamber 14.
  • the chamber 111 is further configured for having the ester liquid 2 extending upwardly into the liquid expansion chamber 14 in case of a volume change of the ester liquid 2 due to temperature variations.
  • the dielectric insulation material forms a layer between each successive conductive layers 121, wherein the layers formed by the dielectric insulation material and the successive conductive layers 121 are each wound around the electrical conductor 13.
  • said layers formed by the dielectric insulation material and the successive conductive layers can be directly or indirectly wound around the electrical conductor 13.
  • the electrical conductor could be a conductive tube serving as winding support for the previously mentioned layers.
  • the electrical conductor could be placed within a tube 15 serving as winding support for said previously mentioned layers.
  • the dielectric insulation material is a plastic mixed dielectric impregnated with the ester liquid, which comprises for instance a plastic foil and a non-woven fabric.
  • the plastic foil and the non-woven fabric have a sandwich structure between two successive conductive layers 121.
  • the dielectric insulation material is a paper impregnated with the ester liquid.
  • the present invention proposes therefore to satisfy the high environmental requirements for a bushing by using as insulating matter a special combination of a dielectric and an ester liquid as impregnation agent within the capacitive graded core of the bushing.
  • the ester liquid according to the invention can be synthetic and/or natural ester liquid.
  • the preferred embodiments result in a capacitive graded high voltage bushing type EIS (ester impregnated synthetic) or in a capacitive graded high voltage bushing type EIP (ester impregnated paper). According to the latter, common paper used in OIP technology is used instead of the plastic mixed dielectric.
  • the present invention has many different advantages over existing solutions, which makes the bushing according to the invention a very attractive product.
  • an advantage of the EIP bushing is that for a manufacturer of established OIP bushing only small adaptions in the production process are required. Furthermore, the EIP and EIS bushings provide more security by using ester liquid which is less inflammable compared to the common used mineral oil.
  • the combination between plastic mixed dielectric or paper dielectric with a special impregnation agent that is natural or synthetic ester provides new application ranges for economic liquid insulated high voltage bushings. Additionally, the bushings according to the invention provide the following advantages compared to prior art bushings:
  • the proposed EIS or EIP technologies are an economical alternative compared to the more expensive solid material technology. Further for EIP technology the same production equipment almost free of adaptation can be used (for instance the winding machine for producing the capacitive graded core of the bushing).
