WZ11-1WHPA 平台三台注水泵和两台外输泵采用自耦变压器启动柜启动,中期改造时已增加了一台变频器,目前需要新增一套外输泵控制柜和变频切换控制柜,实现一台变频器控制三台注水泵和两台外输泵,达到“变频启动切换工频”-“变频控制”,现设置一套一带五变频切换控制系统,将五台泵进行变频启动,减少启动对平台电网的冲击,延长检泵周期.
WZ11-1WHPA 平檯三檯註水泵和兩檯外輸泵採用自耦變壓器啟動櫃啟動,中期改造時已增加瞭一檯變頻器,目前需要新增一套外輸泵控製櫃和變頻切換控製櫃,實現一檯變頻器控製三檯註水泵和兩檯外輸泵,達到“變頻啟動切換工頻”-“變頻控製”,現設置一套一帶五變頻切換控製繫統,將五檯泵進行變頻啟動,減少啟動對平檯電網的遲擊,延長檢泵週期.

The three water injection pumps and two crude oil transfer pumps start by autotransformer on WZ11-1 Platform. Added one variable frequency device in medium-term modification. Require adding crude oil transfer pump control panel and variable frequency switch panel to achieve one variable frequency device control three water injection pumps and two crude oil transfer pumps. to achieve variable frequency and frequency starting switch control. Now five pumps can start by one Change five Control variable frequency system, reduced impact on power system and extended overhaul periods of pump.
