ON THE REASONS FOR ACCIDENTS WITH DEATH OUTCOME IN POWER PLANTS

Abstract. Statistical data on industrial accidents, fatal accidents are presented. Over the past decade, the number of victims of industrial accidents, including fatalities, decreased by almost 2.5 times. It was established that all fatal accidents that occur at electric power enterprises are associated with touching live parts of electrical installations, electric shock, and injuries incompatible with life. An analysis of group accidents, as well as serious accidents and fatal accidents, shows that the causes of accidents can be: poor organization of work during the operation of power plants, low reliability of technical systems of power plants, non-compliance with labor protection instructions when performing work, erroneous and unauthorized actions of employees themselves, etc. Based on the circumstances and causes of group accidents, as well as serious accidents and accidents fatal recommendations are given to reduce the level of occupational injuries and to prevent accidents at electric power enterprises.

Key words: occupational injuries, injured, industrial accident, electric current, injury labor protection requirements.

STUDY OF THE INFLUENCE OF TRANSFORMERS ON THE QUALITY OF ELECTRIC ENERGY IN THE ELECTRICAL SUPPLY SYSTEM

Abstract. Currently, enterprises are increasingly raising the issue of the quality of electric energy, in particular the impact of various electrical equipment on the state of the electric network. One of the possible ways to reduce the risk of lowering the quality of electric energy is to analyze and take into account the effects of various sources of higher harmonics. The aim of the study is to determine the relationship of various operating modes and the technical condition of transformers with parameters of indicators of the quality of electric energy. The analysis of the effect of transformers on the power supply network in normal operation, as well as the effect of transformers with various deviations in the power supply network, on the parameters of the quality indicators of electric energy in the power supply system is carried out. A software model of the power supply system has been developed. In the course of software modeling, three modes of operation in the power supply system were considered: the study of the effect of starting a powerful load through a transformer, the generation of higher harmonics by the transformer in the electric network, the effect of the transformer on the quality indicators of electricity in the power supply system at various levels of harmonics. Timely identification of defects in power transformers that can lead to equipment failure, as well as an assessment of the effect of the transformer on higher harmonics in power supply networks, will not only develop methods to improve the quality index of electric energy, but also significantly reduce the number of accidents that can cause major damage to electric networks.

Key words: harmonics, power supply, technical condition, defects, transformer, accidents, electric networks.

EXPERIMENTAL STUDY OF THE VOLUME ASYMMETRY COEFFICIENT BY REVERSE SEQUENCE IN THE NETWORK OF THE MECHANICAL WORKSHOP OF SIBGAZSTROYDETAL CJSC

Abstract. The problem of the quality of electric energy in the power supply systems of industrial enterprises, in connection with the development and widespread introduction in the production of various high-performance technological installations, such as arc steel-smelting furnaces, welding plants, induction furnaces, etc. continues to be one of the most important ones that determine the reliability and efficiency of power supply to consumers. The voltage asymmetry coefficient in the reverse sequence in a general-purpose power supply system as a distortion parameter is a continuously distributed random variable that depends on many random stationary relatively long-term electromagnetic processes caused by the operating modes of electric consumers, the state of electric networks and their operating modes. A study was conducted in the power supply system of the mechanical workshop of CJSC Sibgazstroydetal in accordance with the requirements of the standard GOST 30804.4.7-2013 and in accordance with the measurement program. Processing of the measurement results was carried out using the software product “Processing of experimental data of electric energy quality indicators by the voltage asymmetry coefficient in the reverse order”, due to which the parameters of the distribution law of the studied quantity were calculated, and the probabilities of the appearance of conductive electromagnetic interference for the calculation period were determined. The analysis of the compliance of this indicator of the quality of electric energy with the requirements of GOST 32144-2013.

Key words: electric power quality, electromagnetic compatibility, voltage asymmetry in the reverse order, GOST 32144-2013, machine shop.

ELIMINATION OF INDUSTRIAL DUST FROM COWSHEDS AND THE EFFECT OF AIR IONIZATION ON THE PRODUCTIVITY AND LEVELS OF GROWTH HORMONE OF DAIRY BREEDS OF COWS

Abstract. Three experiments with dairy cows were conducted in the barn of Dzerzhinsky Plemzavod OJSC in the Yaroslavl Region under controlled conditions. The aim of the study was to determine the effect of a regulated ionic microclimate on the emission of dust particles (aerosol) up to a diameter of 10 mkm (PM10). For the experiment, 18 milk cows were selected, having from 3 to 8 calving, the barn was equipped with a vacuum ventilation system. To control the ionic microclimate, an aeroionizer apparatus was used (maximum voltage 10 kV, current 25 mkA). Thus, the concentration of dust in the air in the barn (42...132 mkg / m3) was reduced by 12.7...26.2%. In experiments B and C, statistical significance P ? 0.05 was achieved. The flow of dust particles from the barn decreased from 7.41...8.63 mg / h to 5.30...6.55 mg / h per animal, i. e. by 24.1...31.3%. As a result of ionization, the ratio of n + to n- ions changed. The unipolarity coefficient was changed from 1.65...1.93 to 0.82...0.89, i. e., the superiority of ions of n - .18 dairy cows was exposed to a vertical electric field of 10 kV / m. The increase in the growth of aeroions especially progressed in the moments associated with the transition to a long 3-hour sessions. It reached 370...380 g per day. Intensive weight gain was due to those nutrients that were previously stored by the body, as well as due to the intensification of metabolism in the body under the influence of ions of negative polarity.

Key words: air, livestock buildings, cows, air ions, animal productivity, aeroionization.

ANALYSIS OF ECONOMIC LOSSES FROM DAMAGE IN DISTRIBUTION ELECTRIC NETWORKS WITH AGRICULTURAL CONSUMERS

Abstract. A structural analysis of technological violations in the Balashikha distribution electric networks with a voltage of 6...10 kV was performed in the period from 01/01/2017 to 12/31/2018, in which there are agricultural consumers of various categories. Technological violations are an integral part in the operation of distribution electric networks and suffer great economic losses both for consumers of various categories and for network organizations. Based on the provided operational journals and lists of serviced electrical equipment by the electric grid organizations serving the Balashikha distribution electric networks, the author conducted a voluminous analytical work and identified the main problem areas, identified the economic losses of agricultural consumers, which should be paid special attention when forecasting repair work and designing new electric networks. The analysis clearly showed that the main problem of the Balashikha distribution electric networks is obsolete and worn cable lines with a voltage of 6...10 kV of the AAB and ASB brands, which require replacement, and in the case of further work, sparing operation and overhaul. The results of the study clearly formulate the problem areas of the Balashikha distribution electric networks and make it possible to use statistical data in the design of future repair work, as well as the formation of a “knowledge base” for creating a neural network for predicting possible technological violations in electric networks.

Key words: technological violation, electric network, damage, cable lines, overhead lines.

REFINEMENT OF RELIABILITY INDICATORS BASED ON THE BAYESIAN APPROACH IN DESIGNING 10 KV AIR LINES

Abstract. The current reliability level of 10 kV distribution air lines and the refinement of reliability indicators based on the Bays approach to design are considered. This topic is relevant, since the inaccuracy of domestic statistics on the damage to rural networks is visible from comparing it with foreign data related to the same networks. In addition, the analysis of literature data on the reliability of electric networks shows that the indicators given in various sources differ in a wide range and are described by various distribution laws. The authors set the task - the refinement of reliability indicators based on the Bayesian approach. This technique and related calculations are presented in detail in the article. The result of the study is that the methodology increases the reliability of calculations on the reliability of 10 kV overhead distribution lines, and can also be used to clarify the reliability indicators of other elements of the electric network, such as transformers, bus structures, automatic sectioning and backup points, etc. the average values of reliability indicators in this case will have a greater degree of accuracy compared to those given in the literature.

Key words: energy, power supply, reliability, distribution networks, methodology, Bayesian approach, maintenance, repair.

ANALYSIS OF OPERATIONAL RELIABILITY OF TRACTORS

Abstract. Currently, the development trends of tractor engineering are focused on the growth of the tractor fleet, increasing the reliability and equal strength of units, reducing the complexity of their technical maintenance (MOT). However, issues related to their overall reliability remain obscured. Information on the reliability of specific samples produced by the domestic industry is either outdated or of a single nature, the same applies to foreign manufacturers. Compare with each other in terms of reliability of different samples is not possible. Thus, the country's agro-industrial complex (AIC) is faced with a choice: either to use its own tractors that have been previously developed and known for reliability, or to purchase more expensive highly reliable foreign analogues. To solve this problem, it is planned to analyze all available information on the reliability of tractors using mathematical statistics procedures and, on this basis, enable industry institutes to expand the source data system in order to more thoroughly study reliability and develop at least some preliminary recommendations for agricultural enterprises of their choice one or another tractor model.

Key words: tractors, analogue, reliability, MTBF, resource, operability, testing, operation.

LAUNCHERS OF HEAT DISPOSAL WITH DEFROSTING SYSTEM

Abstract. In animal husbandry, the creation and maintenance of an optimal microclimate in the animal habitat plays an important role in realizing the genetic potential of animals. Animals emit heat, which needs organization of the conditions of their maintenance, can be used to minimize heating costs. What is especially important in those regions where heating of animal habitats is required. In the structure of heat losses, ventilation of pig-breeding complexes can reach 70...80 % of the total heating costs. Therefore, it is so important to create equipment that could utilize part of this heat and return it back to the room. In view of the fact that ammonia is contained in the ventilation air, it is not possible to use heat regenerators for heat recovery in pig breeding, but it is advisable to use heat recovery units only with the separation of clean and ventilation air flows. A significant part of pig-breeding complexes is located in the central part of Russia, where the duration of negative temperatures is more than 3 months and peak negative temperatures can be below minus 20 ° С. In such operating conditions, additional requirements are imposed on the heat recovery equipment so that it maintains its working capacity and provides the required microclimate parameters. Such equipment can include heat recuperators with plastic air-to-air heat exchangers without separation of flows and with a defrosting system. The test results obtained indicate that the use of the proposed heat recovery unit with a defrosting system allows us to ensure the operability of the equipment at temperatures below minus 10 ° C and to ensure the supply of heated air to the room.

Key words: ventilation, microclimate, heat recovery, heat recovery, pig breeding, microclimate system, heating and ventilation system, energy saving, defrosting system.

GROUPING RESULTS OF THE AGRICULTURAL ENTERPRISES OF THE VOLOGDA REGION BY INDICATORS OF MILK PRODUCTION

Abstract. Agricultural production is gradually increasing the impact on the economic development of not only specific regions, but also of Russia as a whole. Despite the significant difference in the level of efficiency of agricultural enterprises both between regions and between agricultural enterprises within a region, agricultural producers play a significant role in ensuring food stability and security throughout the country. The analysis of production efficiency, technologies and management methods used in leading enterprises allows us to form a development trend, which is a guide for enterprises with a lower level of production efficiency. The Vologda Oblast, being one of the leaders in the production of milk and dairy products, is an example of the introduction of advanced technologies in dairy farming for neighboring regions. Evaluation of the volume and efficiency of milk production is one of the most important tools for monitoring the agricultural industry, which allows us to classify enterprises according to the level of production efficiency in general. The article presents the results of a study of correlation dependencies for the main indicators of economic activity of agricultural enterprises of the Vologda region. Using cluster analysis, a grouping of agricultural enterprises was performed according to the number of cows and the level of milk production, which made it possible to reveal a significant difference in these indicators both among groups and among specific farms.

Key words: agricultural enterprises, production volume, number of cows, milk yield, gross milk yield, cluster analysis, grouping.
