China's first fully grasp the uhv power grid construction technology of the mature first 1000 kv ac power transmission and transformation project - nanyang southeast shanxi ~ ~ jing
China's first fully grasp the uhv power grid construction technology of the mature first kv ac power transmission and transformation project - southeast shanxi try ~ ~ jingmen uhv nanyang alcyy P first kv ac power transmission and transformation project - southeast shanxi ~ nanyang ~ jingmen uhv test demonstration project has been built since put into operation, engineering the safe and stable operation.
This marks China's first comprehensive mastery of the mature of uhv power grid construction process.
The first uhv ac testing demonstration project construction at the end of the year.
Engineering in north shanxi, southeast shanxi substation, the henan nanyang switching station, south to hubei jingmen substation, line 2 km, substation capacity (kva, connecting north China, central China power grid, across shanxi, henan, hubei province.
After the project was put into operation, will make full use of plenty of shanxi coal and hydropower resources, hubei form north and south each other aid across the region economy coordinated development.
Pressure power grid construction requirements are very high, the difficulty is very big.
Uhv grid, the average height of tower is a common kv power grid times of tower height, weight is its times, part of the uhv tower cross arm for meters, equivalent to the width of the storeys high.
Kilovolt power grids to wire up to root, and only root to kv power grid frame of wires.
Construction safety and stability of the uhv power grid, the national power grid companies actively organize construction unit for engineering construction on the bold innovation, has adopted a series of effective new technology, fill the blank of domestic many grid construction technology.
And southeast shanxi ~ nanyang ~ jingmen uhv test demonstration project of the national grid of electricity transmission &transformation facilities of shaanxi engineer zhang, director of the company introduces, of all the construction technology, uhv lines is one of the focus on technology innovation.
In the end, the state grid of electricity transmission &transformation facilities company in shaanxi 'one holding eight pay-off scheme', scientifically solve the uhv lines of technical problems, greatly increase the safety of the uhv wires, now this innovative solutions has been submitted to apply for national science and technology awards.
Southeast shanxi ~ nanyang ~ jingmen uhv test demonstration project is very safe and stable operation, power grid noise is very small, the wire is very smooth, this fully shows that our country has a comprehensive grasp the ripening of uhv power grid construction process.
