Title: Tap switching controller at alternating current and direct current conversion station
Inventor: UEDA HIROSHI
IPC: G05F1/14
Filed: 1981-09-17
Abstract: PURPOSE:To reduce DC transmitted electric power and to shorten the AC voltage drop time of a power inverter side, by performing extremely speedy tap switching when the AC bus voltage of a power rectifier side drops. CONSTITUTION:When the voltage of an AC bus 01 varies slightly, a tap switch 12 performs tap-by-tap upward switching as usual. For example, the AC bus voltage drops greatly and the winding voltage of a reference valve side is compared with the varying winding voltage of the valve side; when a maximum voltage tap selection part 11 detects the fact that the voltage deviation is greater than a prescribed value, the tap selection part 11 shifts into the state wherein a maximum voltage tap is connected, so a maximum voltage tap selection signal is sent to the switch of the tap switch 12 to perform switching to a maximum voltage tap position in known order. Then, a tap state detecting part 14 detects maximum voltage tap selection being performed to open a normally closed contact 15, thus completing the tap switching.

Abstract: PURPOSE: To monitor and evaluate the quality of a synthetic fiber tow by measuring the tension of feeding tow on the upstream side of a roll array for feeding the tow, and using the tension for the measurement of the thickness irregularity of the tow. CONSTITUTION: A plurality of sets of squeezing rolls have fixed and movable rolls. The movable roll applies large pressure to the fixed roll. A tow is elongated by the nip of pair of the squeezing rolls, and fed at the peripheral speed of the throating roll. Tension is generated at the tow at the upstream side from the squeezing roll. If the partial thickness of the tow is different from that of the other, when the part is passed through the intake roll of the tension monitoring unit, the tension is changed at the upstream side of the intake roll. This change is immediately measured by a tension measuring head. The frequency of the changes of the tension and the change of the length due to the change of the tension are measured capable of monitoring the quality of the tow.
