The utility model relates to a modulated digit control circuit of a high pressure reactive power compensating mechanism, which comprises an opto-electrical transmission amplifying and wave shaping circuit, a digital decoding circuit, a pulse out-put circuit, a state sampling circuit, a state detecting and feedback circuit and an electric-light transmission amplifying circuit. The utility model is characterized in that: the parts of the digital circuit are employed with multi-layer SO14, SO16 encapsulation form, the resistance and the capacitance parts are employed with 0603 multi-layer encapsulation form. The said patches are welded on the PCB board and positioned in the metal boot and solidified encapsulated, to form the modulated digital control circuit and connect with a high potential board. After being modulated, due to reducing in size, the digital control circuit is improved in reliability, anti-jamming capacity, convenient maintenance and adjusting, and leaves more space for other parts redistributing on the high potential board, which needs the requirement of higher voltage for the circuit and the parts.
