潜油电动机滑行时间的自动测量

Automatic measurement of sliding time of submersible electric motor.

潜油电动机滑行时间是评定电动机装配质量的重要指标。鉴于手工测量电动机滑行时间存在效率低和误差较大的不足,设计了潜油电动机滑行时间自动测量系统。它通过分压电路和计算机自动测量系统测量潜油电动机定子上感应的电压变化状况,即可得到电动机滑行时间。用手工测量、波形分析和自动测量3种方法测量6种型号电动机的滑行时间,其中5种滑行时间长于3s,判定为合格;1种滑行时间短于3s,判定为不合格。3种方式测量的滑行时间具有较好的一致性,仅波形分析法得出的滑行时间比自动测量的滑行时间稍长,表明自动测量方法的精度和重复性可满足要求。

The sliding time of the submersible electric motor is one of the important parameter for evaluating the assembling quality of the motor. An automatic measuring system for the sliding time of submersible motor is designed in the light of the shortcomings of manual measurement. It determines the sliding time of the motor by measuring the variation of induced voltage on the motor's stator through bleeder circuit and computer measuring system. Contrast analysis shows and test shows that the automatic measuring system is reliable and feasible.
