一、问题的提出在工程设计中,当遇到在一些地区没有电源,或在有比较重要负荷的地区没有备用电源时,常常采用柴油发电机组做为电源或备用电源。柴油发电机组的安装容量,要满足总的负荷要求,在许多情况下,也取决于机组所带最大容量鼠笼电动机的启动要求,如隧道通风机、给水所水泵等拖动电机的电源就是这样。 First, the issue raised In engineering design, when there is no power supply in some areas, or in areas where there is more important load backup power, diesel generators are often used as a power supply or backup power. The installed capacity of a diesel generator sets to meet the total load requirements, in many cases, also depends on the start-up requirements of the squirrel-cage motor with the maximum capacity of the unit, as is the power supply for drag motors such as tunnel ventilators, water supply pumps and the like .
