Mrachkovskyy A. Electromagnetic relay with erosion-steady contact-details in electro plant of agriculture

The object of research is electrothermal and physics-chemical processes on working surface of contact-details of relay, that are pro-ceeding during commutation of current to 10A in condition of exploi-tation. The purpose of research is arising of effectiveness and exploi-tation reliability of electromagnetic relay in agricultural electro plant at the expense of application of new composite contact materials on the basic of theoretical and experimental researches of electrothermal, physical and chemical process on working surfaces of contact-details. Have been passing researches of scientific and practically important questions about providing of exploitation reliability and effectiveness of using of electromagnetic relay into electro plant of agriculture. The main results of the thesis have find instillation into enterprises and plants of agroindustrial complex of Kyiv and Cherkassy Region, Joint-Stock Company JC "Rosava" Bila Tserkva Town, trolleybus repairing and exploitation enterprises of Kyiv, inOAO "AEK "Cher-kassyoblenergo", Joint-Stock Company "A-i-S "Rivneenergo".
