| Popis: |
It is almost impossible to imagine human life without electrical energy in the modern world. The power industry is involved in many areas of human activity. Therefore, improving the reliability of the power supply facilities is a burning issue. This work studies a transformer substation located in an urban area. The research identified the main factors and causes leading to accidents in transformer substations located in urban areas. The fault tree of accidents leading to explosion or fire on transformer station is constructed and analyzed. The probability of the accident has been assessed by the expert method. It has been shown that the most likely causes are mechanical damage to the transformer oil tank and leakage of mineral oil through the welding joint. This work studies the worst scenario, which considers the most severe possible outcome. The calculation has been shown that residential and administrative buildings are located in possible damaged areas. To develop control measures a diagram bow tie was proposed. It presents the barriers aimed at preventing the causes and consequences of accidents. |
