The purpose of work - to develop scientific principles of restoration of contact switching devices by methods of powder metallurgy and electrospark legirovaniya. The methods of researches - Were used determined and probable mathematical and physical models of contact devices. The experimental data were processed with use of methods of mathematical statistics and theory of probabilities. As a result of scientific researches the functional dependences of size of electrical erosion, parameters of reliability contacting and scientifically proved type of a contact material, parity of components in it requirement to technology of drawing of an electrospark covering are established depending on sphere of use of the contact site of electrical devices by a voltage up to 1000 V and rated current up to 250 A. On the basis of microstructural researches the technological parameters of process of drawing of coverings are scientifically proved at restoration of contacts of electrical devices by a voltage up to 1000 In with use electrospark legirovaniya. Is applied in the repair and repair-transport enterprises Agrotehservysa and Ministry of agrarian politics. Product Description popup.authors popup.nrat_date 2020-04-02 Close
