Description
技术领域
本发明涉及一种高压直流电缆的绝缘材料的制备方法，属于电力设备技术领域。
背景技术
柔性直流输电技术是基于电压源换流器的高压直流输电技术，是随着PWM控制技术和电力电子技术发展而来的新型直流输电技术。相较于传统直流输电技术，柔性直流输电技术具有更高的可控性，能够对扰动有更快速的响应，更加方便地控制线路潮流，同时更适合中小功率和远距离输电，因此柔性直流输电技术在城市电网供电、新能源并网、分布式发电并网、孤岛供电、异步交流电网互联等方面具有很强的应用价值和应用前景。
柔性直流输电技术是在可关断器件组成的电压源换流器和交联聚乙烯电缆出现后，采用脉宽调制控制技术而发展起来的。目前使用的电缆绝缘材料一般采用聚乙烯树脂作为基体材料，工作温度在70℃以下且电气性能有限，所以一般适用于中低压电缆。而教练聚乙烯具有较好的热性能和机械性能，能够承受较高的工作温度和电场强度。单交联聚乙烯作为一种热固性材料，难以回收利用，难以降解，经济型较差。
因此需要开发一种电气绝缘性能良好又对环境友好的直流电缆绝缘材料。

所述含有双键的羧酸或其衍生物至少含有一个不饱和碳碳双键和至少一个羧基或酸酐。
所述多胺选自N-芳基苯二胺、氨基咔唑、或氨基吲哚、氨基吡咯中的一种，优选是氨基咔唑。
所述阻燃剂为氧化镁、氧化铝、水玻璃中的一种或多种，优选是氧化镁。
所述抗氧剂是二烷基二苯胺，叔丁基苯酚、烷基叔丁基丙酸酯中的一种。
所述增塑剂是邻苯二甲酸二辛酯、甲酸二异辛酯、邻苯二甲酸二甲酯中一种或多种。
