Improving the heat resistance of polymer electrical insulation systems for the modernization of induction motors
Ensuring high power, efficiency and reliability of induction motor operation while providing small weightβsize parameters represents an up-to-date problem. One of the factors limiting the reduction of weightβsizeparameters when increasing capacities of induction motors is the failure of the insulation system. Therefore, thereis a strong need for studying the issues of slot fill when designing an induction motor, taking into account anincrease in the heat resistance class of electrical insulation systems. The purpose of the present research is todevelop a polymeric electrical insulation system of increased heat resistance for the modernization of aninduction medium-capacity motor to reduce weightβsize parameters and to evaluate the possible savings ofwinding material. The paper deals with an analysis on the statorβslot fill for the induction motor. Modernconductor and insulation materials were selected. The necessary calculations for a mediumβpower inductionmotor of different heat resistance classes were performed. The usage of the proposed electrical insulation systemwas substantiated. The analysis shows the possibility of increasing the heat resistance of the polymer electricalinsulation systems to save winding material for induction motors without reducing the specified quality level

Π΅ Π½Π° 15β18 %.The relevance of the work is caused by the need for a comprehensive mineralogical-geochemical study of gold deposits to create predictive-search models of ore objects. The aim of the research is to study the typomorphic properties of pyrite (crystallomorphology, element-impurities, thermo-emf) from different-temperature mineral associations and generations of ore bodies and near-ore metasomatites of gold ore deposits in the Olkhovsko-Chibizhek ore field. Methods: crystallomorphology, thermo-emf, statistical processing of geochemical data, spatial modeling of typomorphic properties of pyrite. Results. Typomorphic properties of pyrite-crystal - morphology, impurity elements, thermo-emf, naturally vary in the volume of ore bodies in the Olkhovsko-Chibizhek ore field deposits and from early high-temperature mineral associations to the final stages of formation of deposits. Pyrites of deposits of the ore field are mainly represented by crystals of cubic habit, the number of crystals of which regularly decreases from west to east (and wave-like with the depth of ore bodies with wave amplitude 200...240 m) from Lysogorskoe to Medvezhye and Konstantinovskoe deposits. The greatest combination resistance of pyrite crystals in {100}+{210}, {100}+{210}+{111}, and at Lysogorskoe deposit - {100}+{321} (more than 50 %), where the {321} face crystals is poorly developed and is characteristic of lowtemperature mineral associations and upper parts of ore bodie

One of the difficulties of converting wind energy is the low level of energy efficiency of this process. Due to the variable value of the rotational speed of the blades of the wind turbine in a certain time interval, the parameters of the received energy are variable, therefore, the settings of the secondary converters of electric energy must correspond to the time intervals for generating the signal. Improving the functioning of alternative power sources is possible through the use of multi-frequency stabilization modes of the converter. The article considers a model of a pulse-modulation step-down voltage converter based on pulse-frequency modulation. The authors have studied and proposed the methods for changing the width of the working zone of a singlefrequency stabilization mode. The main aim of the study is to analyze the changing modes of the secondary voltage converter of a wind generator and to develop approaches to the study of bifurcation phenomena that occur in a converter with pulse-frequency modulation by constructing a mathematical model and numerically-analytical modeling of a buck voltage converter to improve the reliability of the system under consideration. Methods: study of literature on standard energy conversion schemes in wind turbines with an intermediate DC link; mathematical modeling and conducting numerical experiments to change the operational parameters of a buck converter with pulse-frequency modulation to identify bifurcation in it; construction of bifurcation diagrams for various parameters of the transducer in order to increase the reliability of operation. The results. The authors obtained the mathematical models and numerical-analytical technique for constructing and identifying dynamic modes of a voltage converter with pulse-frequency modulation acting as a DC link of a wind generator set and constructed the bifurcation diagrams for voltage stabilization at different parameters of the control system. The simultaneous presence of single-frequency and burstpacked modes was shown, bifurcation of period division was identified; the influence of the system parameters on the operating modes was studied, and methods for changing the width of the working zone of the single-frequency stabilization mode were proposed

The main aspects, which allow improving these quality factors are: usage of perspective topologies of power part and modern power semiconductor keys, implementation of new control algorithms. In electric drives, where frequency converters are used, there are negative factors, affecting oil-submersible cable and submersible induction motor functioning. Non-sinusoidal voltages at the frequency converter output lead to increased wear and tear of the supply cable insulation, and also negatively affect the insulation of induction motor windings and reduce the quality indicators of electric drive control systems. Consequently, the search for ways to improve the quality of the output voltage and current of the voltage inverters in electric submersible pumps is a critical task. The main aim of the research is to develop the algorithms to improve the reliability indicators of multilevel converters and upgrade the quality of harmonic composition of the output voltage and current of voltage inverters as part of the electric drive of a submersible oilproducing pump. Object: voltage inverters as a part of electric drive of submersible oil producing pump. Methods and tools: reliability theory, harmonic analysis, functional diagrams, switching functions, topology of electric circuits of power converters, numerical methods for solving differential equations, fast Fourier transform, Matlab Simulink. Results. Significant improvement of current and voltage quality factors in multilevel converters as a part of electric drive of submersible oilproducing pump has been demonstrated. Possible ways to improve reliability indicators by changing the layout option of the circuit topology have been considered, with the probability of no-failure operation increasing from 23,70 to 66,10 % as compared to the classical layout. It is established that regulation of switching frequency depending on operating modes in multilevel inverters will allow controlling rationally dynamic losses and loads on power keys
