    • The invention relates to a method for monitoring the function of a rotating electric machine, in particular a dual-feed asynchronous machine with an output range of between 20 and 500 MVA, said machine comprising a rotor that rotates about an axis and is concentrically surrounded by a stator. The rotor and stator have a rotor sheet element and stator sheet element respectively, each made of laminated sheets that are pressed axially into a composite. Said elements are pressed using tension bolts (21) that are electrically insulated from the sheet elements and that run in an axial direction through the rotor sheet element and stator sheet element. In a method of this type, to achieve a simple and reliable monitoring of the insulation of the tension bolts, the insulation of said bolts is continuously measured electrically during the operation of the machine, a predetermined potential in relation to the associated sheet element being applied to each tension bolt (21) by means of a voltage source (24), and the flow of current through the voltage source (24) and/or through each tension bolt (21) is measured and evaluated.
    • 本发明涉及一种用于在20 MVA和500 MVA,它包括一个绕由定子同心地包围的轴之间的功率范围内的双馈异步机器监视的旋转电机的功能,特别地,其中所述转子和所述定子的 已经构建层叠的并且在轴向方向推压,以形成复合片材层压转子体或定子层叠铁芯,其由装置通过对金属片体电绝缘连接螺栓(21)的转子层叠体或定子层叠穿过压在轴向方向上。 在这样的过程中,拉紧螺栓的分离的简单且可靠的监测是在机器的操作过程中实现,即,拉紧螺栓的绝缘连续通过电装置测量的,预定的电压源中的相应装置的张力螺栓(21)(24) 相对于相关联的金属片体的潜力被放置,并且电流流过电压源(24)和/或通过相应的张紧螺栓(21)被测量和评估。
