“xxnxx69.”100米的长xxnxx69.度10毫米的精度,“大风车”叶片如何造?

  随着xxnxx69.气温逐渐走低,各地进入全年xxnxx69.用电高峰,据国家能源局数据显示,目前,我国可再生能源装机容量,占比已经超过总装机容量50%,装机规模不断实现新突破。

  记者近日从甘肃省了解到,甘肃省的新能源装机占比、发电量占比,均居全国第二,电源构成,正在由“以化石能源为主,向大规模可再生能源为主”转变,实现能源生产清洁化。其中,冬季常常吹来的西北风,就起到了很大的作用。

  在甘肃,独特的地理位置,让风在河西走廊形成“狭管效应”,全国首个千万千瓦级风电基地,就分布在河西走廊,这里还有全国陆上最大、产业链条最完备的风电装备制造基地。寒冷冬季,对能源的需求迅速增加,甘肃河西走廊的绿色能源产业开足马力运转。

  酒泉经济技术开发区已经具备年产2450套风机叶片的生产能力。为了能更便捷运输风机叶片等大型零部件,高速公路新设了一个收费站,最靠边的一个车道是超宽超高,可以最多通行150米长叶片,进去收费站的行车道也是有三条普通车道的宽度,可以让拉叶片的大车正常转弯。该收费站预计在本月就会开通,这里生产的风机零部件源源不断地到达全国各地。

  冬日的河西走廊,茫茫戈壁上矗立着无数的“白色巨人”。叶片是风机的重要零部件,长度可以超过百米。

  总台记者焦健:玻璃纤维、连续毡、轻木等主材料会按照设计图纸的要求,以10毫米的精度铺设在风机叶片里不同的位置。最终,风机叶片的根部铺设厚度将达到70层。

  风机叶片是使用复合材料制作的,一个叶片的重量大约有30吨。铺层时较高的精确度既可以控制重量、节约成本,也可以更好契合叶片不同位置需要的不同载荷。

  酒泉经济技术开发区某风电企业副总工程师 贾宏伟:虽然我们叶片是百米级的,但是所有结构布层是按照毫米级的管控要求,单个的玻璃纤维布和芯材,它的铺设的精度要求都能达到毫米级。

  酒泉市工业和信息化局基础产业科科长 陈亚龙:酒泉已建成了一个千万千瓦级风电基地,三个百万千瓦级光电基地,特别是起步较早的风电装备制造产业链,关键零部件已全部实现本地化生产。既满足了本地企业的生产需求,促进了产业链上下游企业的发展壮大,同时主要产品还可以销往外地。
