在潜油电泵机组的选井选泵过程中,既要考虑保证潜油电泵机组的工作可靠性,又要考虑优化配套,节约成本,为用户取得最大的经济效益。本文简要了介绍潜油电泵选井选泵中变频机组变压器选择计算过程,并对应用中容易出现的错误问题分析,进一步指出选井选泵也要重视优选变压器。 During the process of well selection and pump selection of submersible pump units, it is necessary to consider ensuring the reliability of submersible pump units, optimize the facilities and save costs, and maximize the economic benefits for users. This paper briefly introduces the calculation process of VFD transformers in submersible pump selection well pumps, and analyzes the error problems that are easy to appear in the application. It is further pointed out that the selection transformers should be valued as well.
