Nuclear reactor fail-safe unit having the function of control relay and current regulation |
摘要 |
An electronic unit for controlling the safety absorbers of a nuclear reactor comprises a self-supplied AND1 circuit for performing logical multiplication of input signals each capable of assuming one out of two values, series-connected modules each constituted by a dc/ac converter, the output of the last module being coupled to the first converter and to a regulator input at which is obtained a logical a.c. signal whose value corresponds to the result of multiplication of the different input signals, a static intensity regulator with negative current feedback for modulating the width of the square waves delivered by an isolation transformer, a rectifier for delivering a constant current to a load impedance.
