介绍了小型水电站相对于大型电站来说,规模小,投资省,近十几年来,各地都得到大发展。三相短路电流计算在小水电设计、施工、维护和运行过程中占有重要地位,对工程质量、电气安全至关重要,掌握简便快捷的方法,较准确地计算三相短路电流对工作有益。

铝丝铠装短路电流计算探讨 在国外的很多中压单芯电缆中，为了避免涡流损耗，同时保证电缆可承受一定的拉力，铠装 采用的是铝丝铠装。因为在电缆安装实际操作中，铠装和屏蔽一样，都是要接地的。国外的 电力系统大多属于a类系统，即中性点是直接接地的，在这种系统中，需要通过较大的接地 短路电流，即在电缆发生短路时，屏蔽和铠装可以通过比较大的短路电流，将电流导入大地， 而使电缆免于受损。因此，铝丝铠装的短路电流计算，是工程技术人员必备的一种技能。在 iec标准中，并无铝丝铠装短路电流的计算公式，有的只是铜带屏蔽和铜丝屏蔽。但是，依 然可以依据iec标准和参照其他国内外资料，进行铝丝铠装短路电流的计算推导，并得出准 确的经得住实践检验的铝丝铠装短路电流数据，从而在电缆的研发、设计、制造过程中发挥 重要作用。 电缆中任一载流部分，其额定短路电流的计算方法，通常假设在短路
