摘要: 直流电缆系统开发过程中材料选型、制造工艺、验证直流电缆系统可靠性的方法等成为国内外关注的焦点问题。在过去10里,高压直流电缆系统的试验方法体系得到全面的发展,已建立的规范或标准包括CIGRE TB 496、GB/T 31489.1和IEC 62895等,均对直流电缆系统在开发过程中的试验鉴定方法做出了明确要求。依据国产化±535kV直流电缆研发试验经验,综述上述3个标准要求制定的背景,着重梳理对比GB/T 31489.1和IEC 62895在条款规定中的差异性,总结研发过程中绝缘材料电性能评价方法和直流电缆系统在低温环境下电性能型式试验经验,提出在标准化工作中的建议,可作为试验方案制定的参考。

Abstract: How to ensure the material quality, manufacturing process of DC cable and test the reliability of DC cable system effectively has become the focus of attention. In the past decade, the test method of HVDC cable has been developed in an all-round way. The established standards or specifications, including CIGRE TB 496, GB/T 31489.1 and IEC 62895, have made clear requirements for the test methods in the development of DC cable system. In this paper, based on the experience of development of ±535 kV DC cable in China, the background of the above standards are summarized, and the differences between GB/T 31489.1 and IEC 62895 are compared. What’s more, according to the electrical performance evaluation method of insulating materials during the development process of DC cable system and the type test of electrical performance in low temperature environment, some suggestions in the standardization work are put forward, which can be used as references for established the test scheme.
