Switching control between variable frequency and power frequency of emulsion pump in coal mine

摘要: 针对煤矿乳化液泵站采用变频器“一拖多”的多泵联动方案时存在冲击电流大的问题，提出了乳化液泵变频/工频异步切换和同步切换控制方案。现场试验结果表明，变频/工频同步切换控制能更有效地避免冲击电流，真正实现乳化液泵变频至工频的无扰切换。Abstract: In view of problem of high impulse current when scheme of multiple pumps linkage with one frequency converter applied in coal mine emulsion pump station, asynchronous switching and synchronous switching control scheme between variable frequency and power frequency of emulsion pump were proposed. The field test results show that the synchronous switching control can avoid impulse current more effectively and truly realize free switching between variable frequency and power frequency.
