摘要
为了进一步保证矿井安全生产,减少井下掘进工作面无计划停风,采用双风机双电源自动切换对掘进工作面供风。介绍了双风机双电源及自动切换通风系统的组成和功能,阐述了自动切换装置的设计思路和工作原理以及日常运行和维护的要点。
In order to fur th er guarantee the safety in production of the coal mine and reduce the unplanned off-blast, the auto-switchover and double electric motor and double electric sou rce system is adopted to supply the air for the working faces, This paper introd uces the components and functions of the auto-switchover and double electric mot or/double electric source system, expounds the design ideas and working principl es of the auto-switchover unit, and puts forward the points of the routine opera tion and maintenance.
