QK—A型电动潜油泵控制屏

Model QK-A controlling panel of the ESR

中原石油勘探局电潜泵技术研究所研制的QK—A型电动潜油泵控制屏具有短路保护、过流保护、欠载保护、过载保护、单相保护和欠载停机延时自动启动等控制功能 ,特别是过流保护和电流记录仪负载平衡特性 ,具有保护潜油电动机的安全及反映机组真实运行状况的特性。叙述了这种控制屏的技术参数、功能、工作原理、结构、使用条件及应用情况。最后根据油田现场使用情况及油田采油工程的要求提出了 3点改进建议。

Model QK-A controlling panel of the ESP, which has protecting function for short-circuit, over current,under or over load and single phase, and controlling function for delayed rested automatically when stopping caused by lower load, is developed. The protecting function for over current and load balancing function in the current recorder can protect the submersible electric motor and show the real working status of the unit. The technical parameters, worldng principle, stfucture, using condition and application of this type of controlling panel are described. Also several suggestions are put forward.
