Abstract
On the basis of the National Research University "MPEI", within the framework of the project to create a busbar with polymer-gas insulation for the transmission of electricity from offshore wind turbines, a study is being carried out to develop insulating structures for high-voltage busbars. The work is devoted to the development and justification of the design of a special conductor with combined insulation (polymer-gas) for laying in sea water for the transmission of electrical energy from wind turbines, where a polymer coating of current-carrying elements is used to increase the electrical strength and reduce the dimensions of the current conductor, and for to reduce electricity losses, the main gas insulation is used. Technical solutions for the execution of linear and connecting sections of bus ducts with polymer-gas insulation are presented. An analysis of the distribution of the thermal field in the coaxial gap was performed, demonstrating the features of design solutions for linear sections.
According to the calculations, conclusions were drawn about the possibility of using combined insulation in special conductors.
