Description
The article deals with the reliability of the functioning of the equipment of the power supply substation, and the determination of the probability of uninterrupted supply of electricity to consumers. The following are presented: models of failures of separators, models of short-circuit failures, models of failures of disconnectors. Two statistical series for sudden and gradual failures are singled out. The reliability theory is shown as the main distribution of fail-safe time for sudden failures. The conclusions on the presented models are made and the suggestions on introduction into production are given. According to the presented models, it is possible to judge the reliability of the station's operation, which is necessary for implementing measures to improve the reliability of electricity supply in network companies

INCREASING OF THE DEGREE OF BEE COLONIES DEVELOPMENT BY THE APPLICATION OF ELECTRICAL TECHNOLOGIES
Description
The equation describing the whole combination of actions with bees in hives during spring development is obtained. The formula for coefficient of degree of bee colony development during exact period is obtained. The whole combination of electrical technological actions let to increase the bee colony spring development by two times. The counting of the bee keeping labor profitability for the case of application of electrical technologies during winter and spring is carried out. Application of electrical technologies increases the profitability of honey production by two times. The competitiveness of honey bee products could be increased by the way of application of the meanings of efficient electrical technologies targeted onto increasing of honey productivity of bees, increasing of eco-purity of sanitary actions and decreasing of labor content of main technological actions. Using these calculations, you can create an automated climate control system in the hive. To do this, you must also take control laws and apply the appropriate sensors, microcontrollers and executive bodies. All of this will go to the next - higher level of profitability of beekeeping that rose-sieves produced pro-competitive products. To automate the most labor-intensive processes of beekeeping. These processes are pumping honey and labor costs beekeepers to carry out veterinary and sanitary measures

APPLICATION OF ACOUSTIC-MAGNETIC DEVICES IN HEAT SUPPLY SYSTEMS OF GREENHOUSE COMPLEXES
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
The article discusses scale formation problems of greenhouse complexes with geothermal heat sources. Two-circuit geothermal heat supply systems with intermediate heat exchangers are used to prevent equipment and communications scale. Fresh softened water is heated by geothermal heat and is supplied to consumer needs. The heat exchanger and primary circuit communications contacting with the geothermal heat carrier (geothermal water) are subjected to scale formation in the existing system. A scale formation of heat exchange surfaces reduces the efficiency of the heat exchanger and requires a periodic cleaning and causes a chain of economic losses in the production, transportation and consumption of heat. Currently, we use physical, chemical, biological and combined methods of scale formation prevention. The article also considers hypothesis about the effect of an acoustic-magnetic field on solutions. It was found experimentally, that the acoustic-magnetic field affects to characteristics and dimensions of salt crystals. The number of particles increases and solid phase dimensions decrease. A large number of microcrystals suspended in water are formed as a result of the nonchemical acoustic-magnetic treatment of geothermal water. These crystals do not stick to the pipe surface and do not settle to the bottom, may be filtered out and carry out by water flow from the system

Description
Based on this analysis, it was found that it was necessary to develop an electro-activator with adjustable parameters. Analysis of the literature showed that there are no analytical expressions relating the degree of activation solutions, conductivity, temperature and geometric parameters of an electro-activator. The article presents a block diagram of the system "Electro-activator - working solution - weeds", a mathematical model of the subsystem "Electro-activator" allows to describe the parameters of the solution at the outlet of the electro-activator and its mode of operation. An expression is derived which allows to determine the critical mode of installation and adjustment range of current management. When exceeding the rated range of the control the main energy will focus on the process of aerogenesis. We have implemented the coefficient of aerogenesis, which has a significant impact on the temperature of the solution in the chamber and an electrically. This factor must be taken into account as well as the approach mode to the critical or exceeded. The calculation for the resulting mathematical model makes it possible to design an electro-activator for a company which has different water sources and apply different plant protection products. Also, in the future, the result of the research will allow developing engineering techniques for calculations

Description
The article deals with the results of research of acoustic and magnetic field influence on conductivity and pH value of hydroponic solution. For carrying out researches in this area the hypothesis of possibility of nutrient solution influence on ions by means of an acoustic and magnetic field is set up. A laboratory scale plant was constructed for a pilot study of the hypothesis. The solution was moved in the tube passing through a ferrite ring with winding. Thus, the solution was exposed to the influence of acoustic and magnetic field. The object of research was hydroponic solution of (NH4)2SO4; (NH4)2HPO4; K2SO4; Ca(NO3)2; MgSO4 in water having adjusted concentration and acidity. The solution was taken from the tank of laboratory scale plant by means of the pump, passed through the working area of the acoustic and magnetic device, filter, and then was poured into the tank, from which the sample for pH level changing was taken. The pH value was measured at the temperature of 22С by using electronic pH-meter KL-009(1)A. For control of instrument readings acidity was tested by universal test-paper. The initial pH value of solution made 5. As a result of acoustic and magnetic treatment of solution pH value of hydroponic solution increased from 6 to 6.9. The results show the possibility of pH value correction by small energy input

FEASIBILITY STUDY AND IMPLEMENTATION OF PRODUCTION OF ELECTROACTIVATORS
Description
The feasibility study is required in determining the effectiveness of the implementation of electrotechnical products. The main aim is to determine the magnitude of the economic effects of using key and related results in agriculture. The article presents a feasibility study of production and implementation electroactivator device in the production of 5 units monthly, 60 units per year. It is the device cost calculation based on investment, energy costs and wages. Capital investment in new plant is the cost of materials and installation. The magnitude of the value of individual elements of the unit is determined by the price lists. Determining the cost-effectiveness and technical feasibility in the production when introducing electrified units involves additional investment and operating costs, this is reflected in the cost of production. The comparison was made for the device with a new electroactivator developed in KubSAU and using chemical means of Lakmus. Calculations of economic efficiency of investments for the farm which has 225 hectares of arable land have shown that basic income will be obtained by reducing operating costs. Net present value was determined for different levels of the bank rate and inflation
