摘要
阐述了在罐区设计中,由于场地面积较大,低压电动机供电距离较长,造成其短路电流计算及继电保护整定值选择及校验方法与一般情况有所不同。针对实际工程中遇到的问题展开讨论和计算,并给出最终解决方案。
In the design of tank ifeld, the calculation of short-circuit current, the selection of short-circuit protection set value and checking method are different from that in common cases in view of large area of ground and long distance of low voltage power supply. With respect to these features in practice, the discussion and calculation were carried out in this article. And the solution was ifnally presented.
