Analysis of The Emergency of The Power Supply System Mining Enterprise «Nova-Zinc»

The efficiency of power supply systems for mining and industrial enterprises primarily depends on the reliable operation of electrical equipment. The stability of technological processes in the mining industry is significantly affected by harsh operating conditions of equipment, including seasonal temperature fluctuations on a large scale, the presence of various precipitation throughout the year, vibration, dust, etc. The main types of accidents in power supply systems of mining enterprises are insulator damage, phase flooding, line flooding, earth fault, penetration water. The purpose of the research in the article is to analyze emergency situations in the power supply system of the Nova-Zinc mining enterprise from 2019 to 2023 and identify their causes. In addition, the main types of accidents in the power supply systems of mining enterprises have been identified. The following research tasks are described: identification of the main causes of malfunctions in power supply systems; identification of the causes of equipment downtime; provision of recommendations for reducing malfunctions in the power supply system of a mining enterprise.
