| 摘 要： | 在交流三极电器的温升试验中,能否用三极串联通以单相交流试验电流来替代三极中通以交流三相试验电流?这取决于在2种试验方法下,电器各极间的电磁邻近效应是否能够忽略.本文通过理论分析和试验验证得出:具有并联支路的三极电器,其温升试验不可用交流单相串联来替代交流三相.

| Abstract: | For temperature rise test method of AC three-pole apparatus, can the AC three-phase testing current passing through three-pole be superseded by series connection three-pole AC testing current passing through single-phase? It is decided by: under the two test methods, can the electromagnetic proximity effect between every pole of apparatus be ignored? This paper track theory analysis and experiment verification and came to conclusion: for the three-pole apparatus with parallel branch, its temperature rise test method of AC three-phase can not be superseded by AC single-phase series connection. |
