摘　　要：针对生产实践中常用的自耦降压起动方案体积大、成本高的缺点,提出了用一套自耦降压起动装置通过切换来依次起动多台电机的思路,并给出了1用1备两台消防电机泵的实施方案,使柜子体积减小,电器成本降低了约四分之一。The scheme which we can startup many electric machine in turn with switching one autotransformer decrease voltage equipment was put forward.This scheme overcomes the disadvantage of autotransformer decrease voltage startup scheme in common use.The scheme in common use has the disadvantage of having big volume and costing high.This scheme present two electric machine pumps for fire control,one is in use,the other one is in prepare.This scheme reduces the cost one quarter and reduces the cabinet volume as whi...
