A new method has been developed to assess the insulation durability of the VAZ 215/109-6АМО5 asynchronous electric motor, which is used to drive the circulating pumps of the VVER-1000 reactor. The application of this calculation method significantly simplifies and speeds up the process of designing and analyzing insulation systems, as well as electric motors in general. This can contribute to increasing their reliability and efficiency in operational conditions, which is especially important for ensuring the safe operation of nuclear installations.
The article describes in detail all stages of experimental research, including the manufacture of test samples, their testing and comparative analysis of the obtained data. This consistent approach allows not only to check the compliance of the samples with the specified characteristics, but also to evaluate their effectiveness in real operating conditions.
In addition, the results of the comparative analysis can serve as a basis for further research aimed at improving manufacturing technologies and increasing the reliability of materials. An important aspect is also the study of the influence of various factors on the test results, which can help in the formation of recommendations for the practical application of the obtained data in industry.
The study was conducted with the aim of developing an innovative method for calculating the service life, which will contribute to the acceleration of the process of designing the insulation systems of the stator windings of the VAZ 215/109-6АМО5 electric motor. This technique also lays the foundations for the further development of insulation systems in electric motors in general. The results of the conducted research can become an important step in creating reliable and durable insulation systems for the main circulation pumps of nuclear power plants (NPP). This, in turn, will contribute to ensuring the safety of their operation in the conditions typical for work at nuclear power plants, where the reliability and stability of systems are critically important for preventing emergency situations. Improvements in insulation systems and technologies can reduce the risks associated with overheating and electrical breakdown, which is particularly relevant in the context of modern requirements for the insulation of installations in general.
