In accordance with the basis of comparison of different shift for 6kV auxiliary power in power plants,especially on the profound analysis of structure about Vacuum Circuit Breaker,it is concluded that there should be different shift methods of auxiliary power,due to characteristics of auto quick shift and problem of synchronism,and the different shift will be done for the different circumstances.
对发电厂6 kV厂用电的各类切换方式进行了比较,针对真空断路器的结构,厂用电的切换方式、自动快速切换的特点以及同期问题进行了深入的分析,强调了对应不同的实际情况应采取不同的切换动作。
The synchronous high in the cratonic basin is the targe.
克拉通盆地内同期隆起有利于油气的早期运移富集 ;前陆盆地内褶皱—冲断带发育 ,裂隙常构成良好的储层形成晚期油气藏 ;构造枢纽带常构成油气富集带 ;碳酸盐—蒸发岩层序中孔隙—溶洞—裂缝构成完整的储集—渗滤体系 ,在总体上形成复合油气系统。
