【摘要】：隨著直流輸電技術的發(fā)展,直流電纜輸電方式在未來電能傳輸中將發(fā)揮重要作用,而直流電纜輸電技術發(fā)展的關鍵在于電纜絕緣材料的突破。針對傳統(tǒng)交聯聚乙烯絕緣存在的不可回收再利用、工作溫度有限和加工工藝復雜等缺點,開發(fā)環(huán)保型直流電纜絕緣材料顯得尤為必要。為促進環(huán)保型直流電纜絕緣材料的研究和開發(fā),對環(huán)保型直流電纜絕緣材料的發(fā)展現狀和關鍵技術進行了系統(tǒng)評述�？偨Y了目前常見的幾種聚烯烴類環(huán)保型直流電纜絕緣材料的研究進展和聚烯烴材料的3種改性方法:共混改性、納米改性和化學接枝改性,對比了環(huán)保型直流電纜絕緣材料和傳統(tǒng)交聯聚乙烯相比的優(yōu)勢�？梢钥闯�,以熱塑性聚烯烴,特別是聚丙烯為基體的環(huán)保型直流電纜絕緣材料展現出了很好的應用前景,可以有效提高直流電纜的工作溫度,簡化加工工藝。環(huán)保型直流電纜絕緣材料開發(fā)過程中更應注重材料在高溫下的性能,以發(fā)揮其優(yōu)勢從而提高直流電纜的運行溫度,同時應該同步開展環(huán)保型直流電纜絕緣材料的老化研究。
[Abstract]:With the development of DC transmission technology, DC cable transmission mode will play an important role in the future power transmission. The key to the development of DC cable transmission technology lies in the breakthrough of cable insulation materials, aiming at the shortcomings of traditional XLPE insulation, such as non-recycling, limited working temperature and complex processing technology. In order to promote the research and development of environmental protection DC cable insulation material, it is particularly necessary to develop environmental protection DC cable insulation material. The development status and key technologies of environmentally friendly DC cable insulation materials are reviewed systematically. The research progress of several common polyolefin insulation materials for DC cables and three modifications of polyolefin materials are summarized. Sexual approach:. Blending modification. Nano-modification and chemical grafted modification, compared with environmental protection DC cable insulation material compared with traditional cross-linked polyethylene, it can be seen that thermoplastic polyolefin. Especially the environmental protection DC cable insulation material based on polypropylene shows a good application prospect and can effectively improve the working temperature of DC cable. In the process of development of insulating material for environmental protection DC cable, more attention should be paid to the performance of the material at high temperature in order to give play to its advantages and improve the operating temperature of DC cable. At the same time, environmental protection DC cable insulation material aging research should be carried out simultaneously.

【正文快照】： 0引言1相對于交流輸電系統(tǒng),直流系統(tǒng)輸送容量更大,可以節(jié)省大量土地資源,而且直流系統(tǒng)無交流——系統(tǒng)大范圍的連鎖故障風險,系統(tǒng)安全問題較小。因此直流輸電技術將在遠距離、大容量輸電和分布式能源送出等方面被廣泛采用。然而,隨著超/特高壓輸電線路的建設,傳統(tǒng)的架空輸電線
