Similarly when the circuit requires extra gas this is supplied by the tanks through valve h to the low pressure point i. The circuit also includes a compressor z which draws from pipes l, c and feeds into a high pressure tank n which in turn provides make up gas through a valve x to the point g.

Filed: 1974-10-08
Abstract: 1481736 Automatic regulation of reactive current and voltage GENERAL ELECTRIC CO 8 Oct 1974 [12 Oct 1973] 43588/74 Headings G3R and G3X Reactive current compensating apparatus includes a fixed capacitor connected in parallel with a series combination of a fixed inductor and a gated A.C. switch. The firing angle of the switch is controlled to regulate the phase angle between the current and voltage of the supply. As shown, an electric arc furnace 20 is supplied from a generator 10 over a step-down transformer 14. Fixed capacitors 30-32 and timing inductors 33-35 are connected across the supply leads in parallel with inductors 40-42 and series controlled rectifiers 40b-42b. A firing angle control circuit 65 receives a control signal from a circuit 66 which adds together signals derived from a load current sensing circuit 61 representing reactive current, and a line current phase angle sensor 70. In both cases, a measured current value is combined with a voltage signal which is processed by transformer circuits (51, 60) Fig. 3 (not shown), so as to correct for the reactive effects of transformer 14. A feedback limiting circuit (90), Fig. 5 (not shown), is included, and the overall arrangement operates to maintain the phase angle close to zero. That part of the system including angle sensor 70 operates in a feed-forward manner, and compensates the furnace supply so that demand variations do not cause voltage disturbances on additional supply lines 25-27 connected to the generator 10. In addition to arc furnaces, the arrangement is suitable for supplying drag lines, rolling mill drives and high voltage transmission lines.

[Also in Division H2] A reversible input signal is applied to terminals 1, 2, connected to the bases of NPN transistors 3, 4, which are coupled with PNP transistors 5, 6, forming part of a bridge circuit comprising source 7 and balancing potentiometer 8. The output of the bridge circuit is connected to a modulator circuit including complementary transistors 11, 12, which are controlled by alternating voltages derived from oscillator 15 through transformer windings 13, 14. When the potential difference at terminals 1, 2 is such that terminal 9 is positive relative to terminal 10, current passes through transistor 12 and diode 17 to afford an alternating voltage input to amplifier 19 providing four independent signals in circuit 20 for control of the transistors in a reversing bridge of the type described in Specification 1,035,518. When the potential at terminals 9, 10, is reversed, transistor 11 acts as a modulator and amplifier 18 operates circuit 20 for opposite operation of the reversing bridge. In another arrangement, the emitter of each of the complementary transistors is connected through a voltage source to one output terminal of the bridge 5-8, while the base of each of the transistors is connected to the other output terminal. The independent output circuits of the complementary transistors are connected to oscillators for energizing the output circuit, Fig. 3 (not shown). Balancing potentiometers may be associated with the sources. In a further embodiment, voltage sources are connected into the collector circuits of the complementary transistors, Fig. 5 (not shown). The input bridge circuit may be replaced by a valve pre-amplifier, the input terminals 1, 2 being connected to the grid circuit of a valve coupled to two output valves arranged as cathode followers, Fig. 2 (not shown).
