【直流超高压输电技术就还是欧洲牛,因为高压电力电子器件技术牛。】
超高压线路可以使用欧洲高压电力器件吗?
我想他指的是与陶瓷绝缘相比。
行家不敢当,只是碰巧学过,只是觉得视频中的哥们有些狂。例如他说变压器内“一般用陶瓷绝缘,中国用特殊纸”,听上去很高端,不知这小哥懂不懂。导线绝缘是有用特殊纸,但整体重量来自线圈和支撑线圈的构架和外壳。变压器内载流导体产生的电磁力是非常巨大的,没有坚强的构架早就散了,哈哈哈
资料:
In 1953, the first 345 kV line was put into service by American Electric Power in the United States. In Germany in 1957 the first 380 kV overhead power line was commissioned (between the transformer station and Rommerskirchen). In the same year the overhead line traversing of the Strait of Messina went into service in Italy, whose pylons served the Elbe crossing 1. This was used as the model for the building of the Elbe crossing 2 in the second half of the 1970s which saw the construction of the highest overhead line pylons of the world. Earlier, in 1952, the first 380 kV line was put into service in Sweden, in 1000 km (625 miles) between the more populated areas in the south and the largest hydroelectric power stations in the north. Starting from 1967 in Russia, and also in the US and Canada, overhead lines for voltage of 765 kV were built. In 1982 overhead power lines were built in Soviet Union between Elektrostal and the power station at Ekibastuz, this was a three-phase alternating current line at 1150 kV (Powerline Ekibastuz-Kokshetau). In 1999, in Japan the first powerline designed for 1000 kV with 2 circuits were built, the Kita-Iwaki Powerline. In 2003 the building of the highest overhead line commenced in China, the Yangtze River Crossing.

看来是行家,感谢评论。
并非电压越高越牛,超高压输电线路要考虑每公里输电损耗和线路成本比的,并非超距输电就不会去搞超高线路。直流超高压输电技术就还是欧洲牛,因为高压电力电子器件技术牛。
这位口口声声说 “只有中国能够•••”,改为“只有中国建成•••”就客气多了
