TECHNOLOGY OF BUSHING FOR TURBO-POWERGENERATOR

Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2012, Vol 59, Issue 259

Abstract

The article presents a bushing technology implementation to turbo power. A polymeric insulators outer electrical insulation that meets the requirements for bushings for power generators have been developed. It was anticipated that the developed bushings would be cheaper than the imported ones. The paper presents the design and technology of bushings for high voltage electrical turbogenerators, which role is to be an electrical insulation of turbogenerator elements, as well as to be a path for current from the inside of the generator to the grid. The body of bushing was made from epoxy composite using cast method. For the optimal selection of the construction of insulators and to ensure manufacturability, the execution of prototypes of insulators needed a series of studies of material parameters: electrical, mechanical, thermal and taking into account of the environmental policies, which is important in implementing solutions for large scale production. Advantages and disadvantages of this technology are presented. The results of material tests performed on the test model of the insulator are included. The usefulness of selected materials and technologies for the use in the production envisaged.
