CONSUMPTION OF THE WIRE IN CONTACT LINES IN RELATION TO INCREASES IN SPEED AND CURRENT

IL CONSUMO DEL FILO NELLE LINEE DI CONTTATO IN RAPPORTO AGLI AUMENTI DI VELOCITA E DI CORRENTE

An enquiry is made into the effects which the speed of trains and the current absorbed by them has on the consumption of the conductors. Speed and current are considered as independent parameters and their effects are considered through friction, insofar as speed is concerned, and through the joule effect with regard to the current. One reaches the definition of two coefficients, K sub V and K sub I, which quantitize the phenomena referring K sub V to an average speed V sub O, whilst the coefficient K sub I is used to identify levels of wear, choosing as reference the value I of the coefficient K sub I calculated on the wear of the entire network. To the product K sub V - K sub I, calculated line by line, is attributed the significance of the coefficient of wear of the line. The question is handled with a theoretical formulation and thus an experimental control is suggested.
