description: The topic of the final qualifying work: "The study of the characteristics of the wave-like elements of fastening the stator winding of high-voltage electric machines".This work is devoted to the study of wave-like elements of the insulation system, which are designed to prevent the formation of grooved discharges and vibration sparking in the grooved part of high-voltage generators. For a long time, wave-shaped gaskets have been used for these purposes, which fit into the gap between the groove wall and the core of the stator winding. Due to the increase in the characteristics of generators, the efficiency of these elements may decrease, it is necessary to assess the impact of operating conditions on them.For this purpose, studies of samples of fiberglass gaskets were carried out using a technique for determining characteristics under the influence of bending loads using a MARK-10 laboratory installation. The characteristics of materials were also studied under conditions close to operational, namely in the process of thermal aging.Results of the conducted experiments:1. The method of thermal aging and the method of determining the characteristics of samples under the influence of bending loads have been studied..2. The strength of the samples under statistical bending (bending stress) and the modulus of elasticity of each sample were determined.The results can be used to predict the behavior of wavy fiberglass gaskets during operation.
