Proceedings of the Institute of Electrodynamics of the National Academy of Sciences of Ukraine| Резюме: | The main results obtained in the department of electrical and magnetic measurements at the Institute of electrodynamics National Academy of Sciences of Ukraine when performing the applied research work “Creation capacitive meters of effort in tightening prisms of stator core of powerful turbogenerator” (TG) are given. It is shown that the capacitive method of measuring forces with the installation of primary transducers under tightening nuts of prisms of the stator core has advantages over other methods due to its high metrological characteristics and noise immunity. The main results of studies of elements of primary transducers of forces are described: differential and semi-differential capacitive sensors with a variable gap and a tubular force-receiving element. Sensors conversion functions are defined. An overview of the created electrical circuits of secondary converters that provide the necessary characteristics of the conversion “capacitance of the force sensor – output electrical signal” is given. The results of the creation of capacitive meter the stroke of cone disk springs in power accumulators (PA) of the pressure stabilization systems of pressing the stator core of a powerful TG are given. The force in the tightening prisms is determining with use value of the stroke of cone disk springs. The function of transformation of multyelement capacitive sensor with concentric coplanar electrodes is calculated. References 19, figures 8. |
