摘要
变频装置由于具有快速调参、软启停等功能在采油三厂抽油机上得到了规模应用,目前使用比例已经达到47%以上。但运行过程中,生产单位反映应用变频器井进行平衡测试时电流变化大。对应用变频器井在变频状态下变频器前端和后端的电参进行了测试对比,在工频和变频状态下的平衡参数进行了测试分析,探讨了变频器对抽油机平衡度测试的影响。
Frequency converters have been widely used on pumping unit in No.3 Oil Production Plant due to the functions of quickly adjusting parameter, soft-starting and soft-stopping. The used ratio has reached more than47%. However the electric parameter test during operating is inaccuracy after frequency conversion. Because the current change for balance testing during operation is larger after using frequency converter, the electric parameters on the front end and the back end of the inverters have been compared, the balance parameters under power-frequency and variable-frequency for oil pumping unit have been analyzed, the influence of frequency converter on pumping unit balance test has been discussed.
