A VOLTAGE REGULATOR OF TRANSFORMERS

摘要

The invention relates to the electric power engineering. Its purpose is to include the voltage regulators of transformers in the centralized hierarchic voltage and reactive power control system of power transmission lines. The offered voltage regulator of autotransformers (fig.1) is characterized in that it is supplied with an element for determination of a correcting signal and its direction, the output of said element being connected to the input of the regulator's time-delay switch-off element (2). The output of an element (2) is connected to the first input of an element (3), provided for stepwise variation of setting, and a logic element AND (4). At the same time to the second input of an element (4) there is connected to a signal circuit (5), which is predicted for an execution of driving operation of autotransformer's stepping switch, while the output of the element (4) is connected to an element (6), which registers the variation of setting and an instant of performance of switching operation, its output being connected to the additional inputs of elements (3 and 1) in order to return these elements to the initial positions.
