快速切换装置在岳城矿主要通风机供电中的应用

Fast Switching Device Applied to Power Supply of Main Ventilator in Yuecheng Mine

针对高瓦斯矿井岳城煤矿变电所电源切换时间过长,直接影响矿井通风及生产安全等问题,选用RCS-9655S型电源快速切换装置,通过制定快速切换装置的工作逻辑,设计了快速切换装置的自检异常闭锁、保护闭锁、PT断线闭锁、开关位置异常闭锁等闭锁功能,并进行了现场模拟试验,结果表明:RCS-9655S型电源快速切换装置能快速切除故障点,并恢复供电,杜绝了高瓦斯煤矿因双回路供电切换时间过长可能引发的各类事故,消除了安全隐患。

According to the long power switching time in the substation of high gassy Yuecheng Mine which would directly be affected to the mine ventilation,production safety and others,a RCS-9655S mode fast power switching device was applied.With the working logic of the fast switching device set up,the auto detection anomaly interlock,the protection interlock,PT disconnection interlock,the switch position anomaly interlock and other interlock function of the rapid swtching device was designed and the site simulation test was conducted.The results showed that the RCS-9655S power rapid switching device could rapidly cut off the breakdown point and recover the power supply.Thus different accidents possible occurred due to the overlong switching time by the double circuit power supply in the high gassy mine could be eliminated and the safety hidden dangers could be eliminated.
