Description
技术领域：Technical field:
本实用新型涉及电力电缆领域，尤其涉及一种风力发电用电力电缆。The utility model relates to the field of power cables, in particular to a power cable for wind power generation.
背景技术：Background technique:
当今能源革命和低碳经济为主题的绿色浪潮席卷全球，风电是潜力极大的新能源产业。2009年9月我国在联合国气候变化峰会上表示，争取到2020年中国“非化石能源”占一次能源消费比重达到15％，在联合国气候大会上提出到2020年中国单位GDP碳排放在2005年的基础上降低40％～45％的目标。Today's green wave with the theme of energy revolution and low-carbon economy is sweeping the world, and wind power is a new energy industry with great potential. In September 2009, my country stated at the United Nations Climate Change Summit that by 2020 China's "non-fossil energy" accounted for 15% of China's primary energy consumption. 40% to 45% reduction on the basis of the target.
中国的风能资源居世界第三位，仅陆地可利用的风能资源总量即达到2.53亿千瓦，大致相当于250台百万千瓦级火电容量。中国东南沿海的有效风能密度超过200W/m2，沿海岛屿的有效风能密度达300W/m2以上，有效风能利用时间长达6000h以上。东北及内蒙地区有效风能密度在200～300W/m2，有效风力持续时间全年在4000h以上，每平方米面积的有效发电量达245kWh以上。但与风电先进国家相比，与巨大的风能蕴藏量相比，中国风电装机容量实在是太小了，并且，已建成的风电场单机容量也偏小，平均只有591.79kW/台。因此，中国风电业还处于起步阶段，远远满足不了市场的需求。所以从长远看，风力发电场用各类电缆的潜力仍然很大。China's wind energy resources rank third in the world. The total amount of wind energy resources available on land alone reaches 253 million kilowatts, which is roughly equivalent to the capacity of 250 million-kilowatt thermal power plants. The effective wind energy density in the southeast coast of China is over 200W/m 2 , the effective wind energy density in the coastal islands is over 300W/m 2 , and the effective wind energy utilization time is over 6000h. The effective wind energy density in Northeast China and Inner Mongolia is 200-300W/m 2 , the duration of effective wind power is over 4000h throughout the year, and the effective power generation capacity per square meter is over 245kWh. However, compared with advanced wind power countries and the huge wind energy reserves, China's wind power installed capacity is too small, and the single-unit capacity of the built wind farms is also relatively small, with an average of only 591.79kW/unit. Therefore, China's wind power industry is still in its infancy, far from being able to meet the needs of the market. Therefore, in the long run, there is still great potential for various types of cables used in wind farms.
风力发电用特种电缆由于长期运行于室外、垂直悬空敷设、频繁扭转(正反各四周为一次、次数不少于3600次的抗扭转性能)、接触油污(部分)、海水腐蚀(特殊环境)，要求其机械强度高、耐扭(柔软)、耐震动以及耐油等，另外用在寒冷地区的电缆还要耐低温(-40℃)。由于风力发电的环境恶劣，风机使用年限较长，且电缆随风机不断旋转等特点，对电缆的性能要求较高，一直以来，都是大量依赖进口。Due to long-term operation outdoors, vertical suspension laying, frequent torsion (once on each side of the front and back, and no less than 3600 times of torsion resistance), contact with oil pollution (partial), seawater corrosion (special environment), special cables for wind power generation, It is required to have high mechanical strength, torsion resistance (softness), vibration resistance and oil resistance, etc. In addition, cables used in cold regions must also be resistant to low temperature (-40°C). Due to the harsh environment of wind power generation, the long service life of the wind turbines, and the continuous rotation of the cables with the wind turbines, the performance requirements for the cables are high, and they have always relied heavily on imports.
目前，风力发电用电缆的研发还属于起步阶段，随着近年来国内特种电缆生产技术的逐步成熟，国内风电用电缆已开始逐渐替代国外同类产品。At present, the research and development of cables for wind power generation is still in its infancy. With the gradual maturity of domestic special cable production technology in recent years, domestic wind power cables have begun to gradually replace similar foreign products.
