Abstract

The subject of the study is electric equipment system of milk farms at agricultural enterprises. The purpose of this work was the enhancement of operational reliability of electric equipment designed for technological process at milk farms based on the use of results of calculations made for the value of expected economic damage caused by failures of electric motors, and owing to the advancement of technical maintenance system. Effectiveness of the work is defined by evaluation of damage and, therefore, reducing the idle time period for technological equipment involved in various processes, at milk farms, as well as increasing lifetime of electric equipment, at agricultural enterprises. Application of the results of these studies may increase the operational reliability of electric equipment and ensure economical savings owing to the reduction of idle time of technological equipment, at milk farms, making it possible to reduce assets for operation and maintenance purposes by 10% to 15% and to decrease electric power consumption as a result of effective use of electrified machinery.

Introduction

In Russia, a national concept has been developed in the field of energy supply in agriculture for the period until 2020. This concept includes substantial enhancement of power supply reliability, for rural customers, and growth of the effectiveness of use of electric equipment and electrified machinery, at agricultural enterprises.

The importance and timeliness of the research subject and project development are determined by the task of reliability improvement of electric equipment designed for rural application. The same applies to increasing the effectiveness of electrified machinery use in agricultural production. Technical and commercial analysis of electric drive failures in technological equipment is vital for the sake of substantiating the application of innovative strategy for technical maintenance and repair of electric equipment.

In our work, we used materials on the economic evaluation of technological processes (Vasant, Zelinka & Weber, 2019, Kharchenko & Vasant 2020, Kharchenko & Vasant, 2018, Thomas, Karagoz, Ahamed & Vasant 2020, Kharchenko & Vasant 2020). However the existing methods involve complicated calculations and, therefore, are hardly applicable in agricultural production. (A. I. Nekrasov, Yu. S. Borisov, 1995, A. S. Guzachev, V. A. Trushkin. 2017).

The scientific novelty of the carried out research and development includes the obtained calculation data and results of analysis of information for estimating damage due to the failures of electric drive of technological equipment, in animal farming. The effectiveness of the research work is defined by the improvement of equipment reliability, increasing its life span and reducing both failure rate and consumption of labor and material resources for maintaining operability of electro-technical and energy equipment.

An important task is to improve, specify and supplement the existing system of maintenance and repair of electrified equipment for agricultural enterprises and to increase the output of agricultural products by improving the operational reliability of electric equipment, in technological processes.
