Zur Überwachung der Durchflußmengen des flüssigen Kühlmittels und damit zur Überwachung der Entwärmung einer elektrischen Maschine werden die Zuleitungsrohre (12) zu den einzelnen Maschinenteilen, z.B. der Ständerwicklung, in zwei Vorrohre (13, 14) aufgeteilt. An den Enden der Vorrohre (13, 14) sind über halbkreisförmige Sammelrohre (5, 6) die Wicklungsstäbe (2, 3) angeschlossen. Der Kühlmitteldurchfluß in den Wicklungsstäben (2, 3) wird überwacht. in dem die Abweichung der Durchflußmengen in zwei annähernd identischen Zweigen (19, 20) zueinander festgestellt wird. Die Durchflußmengen werden über Meßblenden (15) erfaßt. Unterscheiden sich die Durchflußmengen in den Vorrohren (13, 14) entsteht ein Differenzdruck zwischen den Meßblenden (15), der über einen Differenzdruckaufnehmer (16) erfaßt wird. Über eine Auswerteschaltung (17) wird dann ein Warnsignal abgegeben. |

| 62 | Hydrogen leak monitor for a turbine-generator | EP83100702 | 1983-01-26 | EP0085896A3 | 1984-03-28 | Barton, Sterling Cheney; Pitoniak, Joseph Edward |
A device for monitoring the leakage of cooling gas for a turbogenerator stator into the stator water-cooling system is disclosed. The device is located next to the generator so that the operative elements are at the generator storage tank operating water level. As cooling gas accumulates in the storage tank together with cooling water, the gas displaces the water in the leak monitor until the water level rises to a predetermined, adjustable level. When this level is reached, the gas is vented and the water level is restored to equilibrium. Each cycle is recorded on a leak trip counter. When the leakage rate exceeds a predetermined value, an alarm is triggered. |

The fiber optic sensor system comprises a light source for outputting light in a predetermined range of wavelengths, and an optical fiber comprising a long Fiber Bragg Grating, extending continuously over a length of the optical fiber to provide a continuous measurement region in the optical fiber. The optical fiber is coupled to the wind turbine component such that the continuous measurement region is located at a region of the wind turbine component to be sensed, and such that the grating period at each location in the continuous measurement period is dependent upon the value of the operating parameter at that location. A light detector receives light from the optical fiber, and provides an output signal to the controller indicating the intensity of the received light; based on the detected light, a value for the operating parameter is determined. | ||||||

| 75 | SCALING, DEPOSITION AND GENERAL COPPER CORROSION ELIMINATION IN CLOSED COOLING WATER SYSTEMS | US13258056 | 2010-04-16 | US20120031435A1 | 2012-02-09 | Peter Szakalos; Gunnar Hultqvist; Olle Grinder |
| In closed cooling water systems of the kind where deionized and usually deaerated cooling water comes into contact with copper or copper alloys, the formation of scales, depositions due to general copper corrosion is eliminated by the addition of H2 to the cooling water system. The product formed in anoxic (O2-free) water may be described as CuOyHx, but this product can be reduced and, thus, avoided if a sufficient amount of hydrogen is supplied. The life of the stator coil copper pipe for cooling water in an electric generator can be extended significantly by this invention, which is applicable also to other fields, such as closed cooling water systems for particle accelerators and nuclear fusion reactors (such as ITER), for example. In addition, the maintenance cost for such water cooling systems in contact with copper metal will be reduced drastically. | ||||||
