An impulse exciting system of a vane wheel with an increased exciting force

摘要

There is the impeller of pulsed field magnetization system increased exciting force to use function generator (4), first amplifier (5) and the second power amplifier (11), the reference pulse of output (1) with generator, the input counter (3) of these settings that bring to, whose data inputs, on the blade percussion power band of the output (2) from generator. The output (3) of counter is the input of function generator (4) of bringing to, it is exported as the input for (5) first power amplifiers that bring to, it is the first capacitor device of (6) of bringing to that it, which is exported, whose second outlet is connected to first excitation electromagnet (7) an of terminal, whose Second terminal be connected to first resistor device first terminal (8) and, meanwhile with the input terminal of photo-coupler (9). The second end (8) of first resistor device is connected to ground connection (15), simultaneously, the output end (9) of photo-coupler be bring to incoming timing circuit (10) output be bring to input the second power amplifier (11), it is that the second of 1 terminal whose Second terminal that brings to is connected to a terminal of capacitor (12) that it, which is exported, second excitation electromagnet (13) whose Second terminal is connected to the first end point (14) of second resistance, whose Second terminal is connected to public (15).
