description: The subject of the graduate qualification work is âInvestigation of fire-resistance of cables in the own needs system 0,4 kV of a nuclear power plantâ. The given work is devoted to the design of the electrical part of a nuclear power plant and to the investigation of fire-resistance of cables in the own needs system 0,4 kV. The research set the following goals: 1. Selection of the main electrical equipment. 2. Calculation of short-circuit currents. 3. Selection of switching devices, measuring transformers, current-carrying parts. 4. Selection of scheme and equipment in the own needs system 0,4 kV. 5. Calculation of fire-resistance of cables 0,4 kV. 6. Analysis of the results. As a result, the electrical part of the NPP with three VVERâ1000 reactors was designed. The main electrical equipment are chosen, short-circuit currents are calculated, electric apparatuses and current-carrying parts of the station are selected. A review of normative and technical documentation of testing cable lines for fire-resistance was carried out. Calculation of fire-resistance of cables in the own needs system 0,4 kV was carried out. The types of short circuits leading to the maximum heating of the cable are analyzed. Conclusions are drawn about the fire-resistance of 0,4 kV cables.
