ANALYSIS OF MODERN METHODS OF DIAGNOSTICS OF THE TECHNICAL CONDITION OF ASYNCHRONOUS ENGINES
The decisive condition for the introduction of efficient maintenance and repair of electric transport, management of its technical condition is the application of methods and means of diagnostics of rolling stock of electric transport. This allows you to move from scheduled maintenance and repair periodically (regardless of condition) to scheduled control and maintenance, repair as needed depending on the state of rolling stock [1,2].
Such a strategy dramatically reduces the number of repairs, reduces the cost of spare parts, increases the actual overhaul. Therefore, there is a need for theoretical substantiation of perspective directions of development of methods and means of technical diagnostics of electric transport.
Domestic and foreign experience shows that the introduction of promising means of diagnosis is one of the most important factors in detecting and preventing failures and damages of electrical equipment and automated electric drive systems in the general industry and in transport. This allows to maintain operational performance within the established limits and to predict the condition of equipment and elements for the full use of the resource. The combination of methods of diagnosis helps to increase the economic efficiency of the use of electrical equipment in vehicles, industrial and repair companies.
At present, induction motors are the main consumers of electricity in Ukraine, which are widely used in electric drive systems of industry, transport, everyday life and more. But during their operation there is a large number of failures due to emergency situations, which annually account for 20-25% or more of the total number of installed motors.
The failure of the AD does great damage to the objects where they can be used. This situation generally results in damage due to downtime of the process equipment or damage to the product due to an engine failure.
Thus, the task of reducing the level of direct and indirect costs in the operation of induction motors, improving the quality of their diagnostics, as well as improving their reliability are relevant at this time in any industry.
