| 摘 要： | 港口码头、堆场照明设计具有配电路较长，末端为单相用电设备，且设备功率较大的特点。由于配电线路中的相保阻抗相对较大，使得线路末端单相短路电流较小，从而成为设计中不可忽视的问题之一。

| Abstract: | The lighting design of wharfs and yards features long distribution lines and terminal single-phase electric equipments of high power.The higher impedance between the phase line and the PE line results in weaker single-phase short-circuit current at the terminal of the lines,which is not to be ignored when designing this kind of circuit. |

| Keywords: | Large-area lighting Single-phase short-circuit |
