где lk - длина катушки;
Sп. р. х. - величина полного рабочего хода штока,
а длина шунта равна удвоенной длине катушки с магнитопроводом, причем на первичные обмотки индикаторов подают напряжение питания переменным током, а со вторичных обмоток снимают напряжение сигнала о положении шунта или, что то же самое штока, при этом каждому шагу приводного устройства и, соответственно положению штока, соответствует только одна кодовая комбинация соотношения напряжений со вторичных обмоток и абсолютных значений этих напряжений.The control mechanism of a nuclear reactor with a step-by-step sensor for controlling the position of the regulator, comprising a rod, a shunt and a drive device rigidly connected to the regulator located inside a sealed enclosure filled with primary water, indicators of the position of the shunt and windings of the electromagnets of the drive device located outside the sealed enclosure made in the form of two concentric connected in the upper part of the pipes, coaxially with which is located the shunt covering the small pipe, the shunt is installed flax at the upper end of the rod, and indicators of the position of the shunt are placed inside the small pipe in the area of the drive device along the axis of movement of the rod, characterized in that the indicators of the position of the shunt are made in the form of two identical coils with magnetic cores and two windings installed close to each other, the plane of the turns the windings are located in the direction of movement of the shunt, and thus the magnetic lines of force covering the turns of the windings are closed in planes perpendicular to the direction of movement of the shunt, and the length of one atoms with a magnetic circuit selected from the ratio
where l k is the length of the coil;
Sp. R. x - the value of the full stroke of the rod,
and the length of the shunt is equal to twice the length of the coil with the magnetic circuit, moreover, the primary windings of the indicators are supplied with AC voltage, and the secondary windings are removed from the signal voltage of the position of the shunt or, what is the same rod, with each step of the drive device and, accordingly, the position of the rod corresponds to only one code combination of the ratio of the voltages from the secondary windings and the absolute values of these voltages.
