Main transformer foundation of 1000kV transformer substation

Abstract

The invention discloses a flood preventing system used for a substation project. The flood preventing system used for the substation project comprises a flood preventing wall, a water draining pipe, a flood preventing gate, a fastening device, a gate chamber and a water level monitoring meter. The flood preventing wall adopts a cast-in-place reinforcement concrete flood preventing wall, and top elevation of the flood preventing wall is higher than the flood preventing water level; the water draining pipe of the flood preventing wall is arranged according to the requirement of a normal retaining wall, and a check valve is installed in the water draining pipe; the electric flood preventing gate is installed at the outer side of a substation door, and a gate controlling system is installed in a substation; the fastening device is arranged on the flood preventing gate, so that absolute sealing of the flood preventing gate and the door is realized; the door chamber is used for storing the flood preventing gate in an opening status; and the water level monitoring meter can monitor the water level situation of the substation in real time. According to the flood preventing system used for the substation project, the door is blocked by adopting the electric flood preventing gate, the flood preventing gate and the door are absolutely sealed through the fastening device, automatic real-time opening and closing of the flood preventing gate are realized by monitoring changes of the water level, and the defect of flood preventing and sealing of the substation door with the adoption of a flood preventing wall scheme is overcome.

Description

technical field [0001] The invention relates to a main transformer foundation of a 1000kV substation, belonging to the technical field of substation structure construction. Background technique [0002] At present, the foundation of the main transformer that has been built or is under construction generally adopts a reinforced concrete raft foundation. For high-intensity areas, in order to reduce the destructive impact of earthquakes on the main transformer, it is necessary to install a seismic isolation device between the main transformer equipment and the foundation. At the same time, in order to shorten the replacement time of the backup phase of the UHV substation, the replacement of the backup phase of the main transformer needs to adopt the rail transportation scheme. Quick handling. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the existing technology and solve the problems of the traditional concrete raft foundation such as s...
