Annotation
The article is devoted to the study of electric shock to a person during the operation of mining equipment. To solve the issues of ensuring electrical safety and safe operation of electrical installations, a systematic approach is proposed in the work, which consists in the scientific substantiation and development of a practical implementation of the electrical safety management system. The purpose of the work is to study measures to ensure electrical safety in electrical networks with voltage up to 1 kV with various neutral modes. The principles, main provisions of the system analysis of electrical safety at mining enterprises are given. A structural diagram of the relationship between the elements of the power supply system of electric installations in the mining industry is presented. The operating mode of electrical networks with voltage up to 1 kV and electrical equipment of the mining industry has been investigated. The starting characteristics of mining machines are investigated on the basis of the operational properties of electrical equipment. The calculation of the characteristics of the influence of electric current on the human body during the operation of electrical installations at mining enterprises has been carried out. As a check of the research results, experiments were carried out on the basis of the scientific laboratory of the fundamentals of electrical safety of the Department of Power Supply and Automation of KhPITTU.
