摘要
随着大型矿井地面生产系统生产能力的扩大,单台设备的电动机容量也随之增大,提高地面生产系统的电压等级势在必行。本文就地面供电电压等级由380V提高到660V电压技术问题进行探讨。
With the extending of production capacity of large mine surface production system, the motor capacity of single equipment is also enlarged; thus it is necessary to improve the voltage class of surface production system. The paper discusses the technique of increasing surface power voltage class from 380V to 660V.
