Автоматизований контроль параметрів крокових електромеханічних перетворювачів

Abstract

By a mathematical modeling the work features and co-operating with the sensors of stepping transformers are set. In theory grounded, that the angular measuring transformation performance is limited to duration of transient of rotor oscillation which does not exceed 0.5 s. The necessity tuning of voltage frequency is shown, that allows to avoid additional errors, as a result of premature completion of measuring process, and to promote a performance due to diminishing of voltage frequency. The criterion of stepping transformers exiting from synchronism, which consists in comparison of the measured angular value during a transient with the basic value of step, is offered, that allows to automatize the process of starting torque measuring control. The method of angular positions measuring control, which allows attaining the maximal performance value which is limited to duration of control object transient, is developed in dissertation work. The method of the automated metrology attestation and setting of errors norms of working off a step is offered, that allows classifying control objects for to the classes of exactness. Software is developed for the design of electromechanics processes in the stepping transformers in static and starting work modes. The model standard of stepping electromechanics transformers control parameters, which, unlike existing, provides a maximally possible performance is developed, and control veracity fully confirm to the rationed value of the known serial and experimental standards. The designed control device works in three norms setting modes: static and starting characteristics and angular positions, that allows to test and attestation of stepping electromechanics transformers in full. Experimental researches of the stepping electromechanics transformers parameters automated control of are conducted; adequacy of the developed mathematical models is tested.
