| 摘 要： | 针对新乡市某降压变电站负荷难以满足该地区发展需要的问题,对其进行了改扩建设计:电气主接线采用单母线分段接线,主变压器选择中性点直接接地方式;计算最大/最小运行方式下的短路电流,并据此对部分电气设备进行了选择.

| Abstract: | Aiming at the probelm that a Xinxiang City’s stepdown transformer substation load doesn’t meet the requirement of development in this area,the expansion and improvement design were carried out.The lord wiring used a single bus wiring for subsection,the main transformer chose neutral grounding method directly,the short-circuit current was calcutated at the biggest/minimum operational modes.Therefore,some electrical equiments were selected. |

| Keywords: | transformer substation expansion lord wiring design short-circuit current calculation |
