摘要： PROBLEM TO BE SOLVED: To shorten the time required for restarting by detecting a residual voltage when a motor is in the free-running condition, obtaining a corrected number of rotation instructing value by obtaining the frequency and phase from such residual voltage, and then forming a gate signal. SOLUTION: A residual voltage when a motor 11 is in the free-running condition is detected with a transformer 13 for a gage and a velocity setting device 17 obtains the corrected number of rotations command value obtaining frequency and phase from such residual voltage. A gate signal generator 18 generates a gate signal based on a timing matching signal for matching the corrected number of rotation instruction and the phase, and then outputs this gate signal to a VVVF device 12, and the ignition timing of the switching element can be changed. Accordingly, an AC power synchronized with the residual voltage during the free-running may be supplied from the VVVF device 12, and the number of rotation instruction value comes near to the actual number of rotations of the motor 11. The time required to restart the motor 11 can be shortened with improvement in the tracking ability to velocity.

摘要： PURPOSE:To exactly detect a liquid level by providing a movable body following the change of the level of liquid for cooling in a rotor and a photosensor detecting its floating level. CONSTITUTION:Light is cast from a lighting device 12 to a liquid level detector inside a rotor with using a light casting photofiber 13 for leveling in 4 for example. At the liquid detection level, a moving body 11 following the change of the liquid level 5 is provided. If the liquid level in the rotor is at F, the upper two lights from the photofiber 13 are blocked and lower two lights are transmitted through the photofibers 15 for light reception to the level 1 detector 14a and the level 2 detector 14b in the light reception device 14, respectively, and thus, the liquid level is detected. Following the lowering of the liquid level, the movable body 11 also lowers and the light is not transmitted in the detector 14b and the detector 14a in this order and thus, the lowering of the liquid level is judged. When the liquid level 5 rises, conversely, the movable body 1 rises, the light is transmitted in the level 3 detector 14c and the level 4 detector 14d in this order, and the rise of the liquid level 5 is judged.

摘要： PURPOSE:To enable maintenance and safety operation on an on-line by regulating hydrogen-gas pressure in a hydrogen-cooled rotary electric machine in response to load fluctuation by using a hydrogen-reserve alloy. CONSTITUTION:Hydrogen-gas pressure in the housing case 2-1 of a hydrogen- reserve alloy and hydrogen gas pressure in a hydrogen-reserve alloy housing case 102 for a sample are monitored periodically by a deterioration detecting deciding device 12, thus easily detecting the deterioration of the hydrogen-reserve alloy. The hydrogen reserve alloy, a lifetime of which is decided to expire by deciding the deterioration of the hydrogen-reserve alloy, is detached automatically from a hydrogen-gas circulation system. An other case 2-2-2-n system in which the previously mounted hydrogen-reserve alloy is housed is utilized automatically. The hydrogen-reserve alloy as content is replaced with new one in the detached hydrogen-reserve alloy housing case 2-1 and the housing case 2-1 is connected again for spare, and the housing case 2-1 is used as the hydrogen-gas pressure regulator of a hydrogen-cooled rotary electric machine 1.

摘要： PURPOSE:To increase a degree of accuracy of detection and to reduce an operator's burden by making running operation accurate by setting automatically the most effective operation continuable time in case of successful run-back operations and outputting a generator stop signal. CONSTITUTION:When troubles come to a cooling water system of a stator cooling water generator 1, a run-back signal is inputted to a run-back signal detection circuit 3, and the current value detected by a current detection circuit 4 is inputted to a current value comparative circuit 7. When the detected current value is in excess of a setting current value of a current value setting 6, it is made a decision that a run-back operation is not normally conducted, and a generator stop signal is outputted to an output circuit 14. In case of the reverse, a normal run-back operation signal is inputted to a normal run-back operation signal detection circuit 8, and conductivity of cooling water detected by a conductivity detection circuit 9 is inputted to a operation continuable time setting circuit 12. Detected conductivity is compared with conductivity of a conductivity setting 11 by the circuit 12, and when it exceeds the continuous operable hour, the generator stop signal is outputted.
