~~~Transport power engineering~~~
The article describes the design features of the current collection system of the Moscow monorail and revealed its shortcomings, limiting the possibility of increasing the speed of electric rolling stock. The features of a promising new generation of monorail transport system with increasing speed (up to 150 km / h), the message "city - the airport," which is proposed to use the contact current collection system with flat working surfaces of the current collector and the current lead. The aim of the work was to develop measures and technical solutions for improving the current collectors to provide reliable, cost-effective and environmentally-friendly electric power transmission on board the electric rolling monorail transport systems. The proposed technical solutions have allowed to increase the average life of the contact elements of the current collectors of electric rolling on the active sites of the Moscow monorail from 30 days to 5 months. A preliminary design and manufactured model sample collector rolling device for the new generation of monorail transport system with increased speed. A basic model of the pantograph, which allows to unify all the major components and spare parts for the current collectors of options for different speeds, load current, and other operating conditions and choose the appropriate model, taking into account technical and economic feasibility. The results can be used for the improvement of existing and development of new designs for current collectors of electric rolling monorail transport systems for the high speeds.
