An alternative to the existing 500 kV outdoor switchgear equipment located at the Volzhskaya hydroelectric power station is presented, which consists in replacing outdated equipment with a fundamentally new gas-insulated one. The transmission lines from the generator block to the 500 kV complete switchgear have been replaced. The location of the new switchgear has been selected. The operating experience of the gas-insulated complete switchgear has been studied. In the course 3 of the work, short-circuit currents were calculated on the tires of the 220 kV and 500 kV open switchgear. A new scheme of primary connections of complete switchgear with 500 kV gas insulation is presented. |
