The invention provides a frame prefabricated ultra-high voltage or ultra-high voltage substation including: high, medium and low voltage outlets; high, medium and low voltage busbars; high, medium and low voltage isolating switches; high, medium and low voltage switches; transformers; it is characterized in that it also includes a frame, and the frame is a steel structure; The high and medium voltage outgoing lines are located in three directions different from the transformer, the high and medium voltage busbars are located in the middle of the frame, and the high, medium and low voltage isolation switches, high, medium and low voltage switches, and transformers are located at the bottom of the frame. Therefore, the ultra-high voltage or ultra-high voltage substation occupies a small area, has no intersection of lines, and has low maintenance costs.
Description
technical field [0001] The invention relates to a frame prefabricated high-voltage substation in the technical field of electric power engineering, in particular to a frame prefabricated high-voltage substation with a voltage level of 330kV-1000kV. Background technique [0002] With the advancement of technology and the improvement of the national grid construction, the problem of insufficient power supply capacity can be effectively alleviated by transporting electric energy from remote areas to areas with strong electricity demand through the high-voltage power grid; The power loss in the process is small, so it will become the main system of China's power grid in the future. Therefore, it is very important to study this kind of substation. [0003] In the ultra-high voltage or ultra-high voltage substation in the prior art, there are the following problems: Compared with the conventional substation, the scale and wiring form of the ultra-high voltage or ultra-high voltag...
