Definitions

  • Winding arrangement with a winding body and through or inserted optical waveguide
  • the invention relates to a winding arrangement with at least one multi-layer winding body composed of a plurality of turns of at least one winding tape and an optical waveguide which is guided through the winding body or into the winding body.
  • Such a winding arrangement can be used, for example, in an optically monitored electrical device in the field of electrical energy generation and distribution.
  • the electrical device can be designed as an electrical generator or as an electrical transformer.
  • Such an electrical device is a very expensive and long-lived investment. Its failure can be associated with very high costs. For this reason, the use of a diagnostic system, which in particular can also include an optical measuring device, for the early detection of defects, such as overheating or an electrical flashover, is increasingly being considered.
  • the design of a device used in electrical power generation has already been optimized in many ways. In particular, a very compact design has now been achieved in which, at least in the active part of the electrical device, a sensor with a larger space requirement cannot be accommodated without complex redesign of the electrical device.
  • an electrical sensor can therefore often not be used in such an electrical device.
  • an optical sensor in particular a fiber-optic sensor, is much more suitable. The latter has a very small size.
  • a high potential difference can also be bridged without any problems.
  • an optical measuring device for monitoring an electrical device used in electrical energy generation and distribution has already been described many times. As revealed by the review article "Fiber Sensors for Industrial Applications” by M. Lequime, 12 th Internati onal Conference on Optical Fiber Sensors, 28 -31. 10. 1997, pp. 66-71, an optical measuring device for an electric generator. About With this measuring device, an optical sensor detects the vibration spectrum and the temperature of the coolant used to cool an electrical conductor.
  • Another optical measuring device for temperature detection in a 900 MW turbogenerator is from the technical article

  • Optical waveguide as part of an electrical generator monitored by an optical measuring device
  • FIG. 2 shows a longitudinal section through the winding arrangement of FIG. 1 and FIGS. 3 and 4 embodiments of the optical waveguide used in the winding arrangement according to FIGS. 1 and 2.
  • an electrical generator 80 is indicated, which includes a stator 81 and a rotor 82.
  • the electrical generator 80 is monitored via an optical measuring device 100, which is intended for optical measurement variable detection within the generator 80.
  • the optical measuring device 100 contains an evaluation unit 70 which is arranged outside the generator 80 and is optically connected to the interior of the generator 80, in particular to the stator 81, via an optical waveguide 30. At least one optical measuring point in the generator 80 is queried by means of a light signal LS transmitted via the optical waveguide 30.
  • the electrical generator 80 shown in FIG. 1 is designed for a high electrical output, in particular of more than 100 MW.

  • Winding body 91 between two winding layers 92 In addition, for example, at least one optical sensor provided for detecting a measured variable is also arranged within the winding body 91 between two winding layers 92. This optical sensor is queried via the optical waveguide 30.

Abstract

Le dispositif d'enroulement comprend un corps d'enroulement multicouche (91) composé d'une pluralité de spires d'une bande d'enroulement (93), et un guide d'ondes optiques (30) traversant le corps d'enroulement (91) ou introduit dans celui-ci. Le guide d'ondes optiques (30) est enroulé dans le corps d'enroulement (91), dans la zone (95) où il traverse ou est introduit dans celui-ci, et comprend au moins dans ladite zone (95), une fibre optique (32) et une couche protectrice (33) appliquée sur celle-ci. La couche protectrice est constituée entièrement ou partiellement par une couche en un matériau protecteur d'un module d'élasticité maximum de 2,5 Gpa.
