Background
According to the planning, tens of extra-high voltage direct current projects are built in China in the next 10-20 years, an extra-high voltage alternating current and direct current series-parallel power grid is gradually formed, and the extra-high voltage direct current and alternating current system supplies power to the load center in the middle east. In order to solve the problems that a multi-feed-in direct current system is insufficient in voltage reactive power supporting capability of a receiving-end power grid, short-circuit current is crossed due to dense system sending-out and the like, the ultrahigh voltage layered direct current becomes a new direct current access mode. Compared with the conventional ultrahigh voltage direct current, the method has the main difference that the high-end converter transformer and the low-end converter transformer on the inversion side are respectively connected to 500kV and 1000kV power grids, and the alternating current filter and the reactive compensation device are also respectively connected to 500kV and 1000kV power grids.
However, when the extra-high voltage power transmission tower is built, most of the old iron towers and the newly built new iron tower are on the same path, and the construction can be carried out only after the original line ground wire and the iron tower are dismantled. The dismantling of the angle iron tower in China also belongs to a primary stage, needs to be carried out by workers, and is high in labor intensity, low in working efficiency and high in danger. In the angle iron tower, the blasting cannot be performed through punching, only the blasting can be performed in an exposed mode, a large part of energy is emitted to the air, and the blasting effect is poor. Because the power transmission tower is located in the mountainous area, sufficient electric power is not available, welding cannot be carried out on the site, and the mountainous area is inconvenient to traffic and cannot transport materials in large batches.
