近日,洗选中心哈拉沟选煤厂为该厂的5台软启动器增设了备用回路,将软启动器故障处理时间从4 h变为4 min。软启动器是一种集电机软起动、软停车、轻载节能和多种保护功能于一体的新颖电机控制装置。哈拉沟选煤厂目前在部分胶带机和水泵的电机启动时使用软启动器控制。而生产过程中软启动器一旦出现问题,更换软启动器最少需要4 h,如果是控制该厂主要胶带机的软启动器故障,将直接影响正常生产。
Recently, the Halagou Coal Preparation Plant of the washing center has added a backup circuit to the five soft starters of the plant, changing the soft starter fault handling time from 4 hours to 4 minutes. Soft starter is a set of motor soft start, soft parking, light load saving and a variety of protection functions in one of the new motor control device. The Halagou coal preparation plant is currently using softstarters for motor control of some tape and pumps. The production process in the event of a problem with the soft starter, replace the soft starter at least 4 h, if it is to control the plant’s main tape machine soft starter failure, will directly affect the normal production.
