<p>PURPOSE:To recover voltage when the voltage of a self-excited AC generator abnormally lowers, by adding a voltage drop detecting circuit and a thyristor forced ignition circuit to an exciting circuit of the generator. CONSTITUTION:When the voltage abnormally lowers and an automatic pulse phase shifter cannot by operated after the voltage a generator becomes fixed, the voltage of the generator is recovered by working a voltage drop detector 4 and a thyristor forced ignition circuit 5, and the voltage loss of the generator is prevented.</p> |
