Mathematical model for evaluating the reliability of interturn insulation of electrical machines of publishing and printing complexes and methods for its calculation

V. Manko, V. Zotov

Abstract

The article suggests ways to study and control the state of stator winding insulation of electrical machines of printing complexes. A mathematical model for evaluating the reliability of interturn insulation and methods of its calculation is developed, which makes it possible to determine the dependence of the probability of failure-free operation of winding insulation on time for given conditions. The analysis of the action of commutation overvoltage in sections and coils of windings due to mixing of wires at their pouring in a groove

Keywords

reliability, interturn insulation, winding, electrical machine, probability, distribution of stresses, time interval
