摘要
随着"一带一路"建设的不断推进,电力设备的出口已成为行业发展的必然趋势。然而,国产控制保护设备,特别是高压断路器的操作回路,在装置设计和运行维护习惯上与海外产品存在不小差异。国内设计理念往往无法被海外同行接受。为提高国内操作回路在海外的适用性,从装置配置、回路设计、运行维护习惯以及与一次设备配合等方面对国内外高压断路器操作回路进行比较研究。研究总结了国内外技术方案的差异,基于±800 k V美丽山II回直流输电工程电气二次的设计经验,分析国内外技术差异的内涵,指出相关国产设备海外推广需要解决的关键问题。
With the continuous promotion of " the Belt and Road" construction,the export of power equipment has become an inevitable trend of industry development. However,the domestic control and protection equipment,especially the operation circuit of high-voltage circuit-breaker,is quite different from overseas products in device design,operation and maintenance habits. As a result,the domestic design concept is often not accepted by overseas counterparts. In order to improve the applicability of domestic operation circuit in overseas countries,a comparative study on the operation circuit of domestic and foreign high-voltage circuit-breakers is carried out from the aspects of device configuration,circuit design,operation and maintenance habits and coordination with primary equipment. The differences between domestic and foreign technical solutions is summarized. Based on the experiences of electrical secondary design of ± 800 k V Belo Mount II DC transmission project,the connotation of domestic and foreign technical differences is analyzed,and the key problems to be solved for overseas promotion of the relevant domestic equipment are pointed out.
