| 158 | Process and device for quickly reducing pressure in an installation, in particular a hydrogen-cooled generator | US48 | 1998-01-23 | US6086333A | 2000-07-11 | Joachim Krutzfeldt; Rudolf Von Musil |

The hydrogen-cooled generator system at least includes a first and second housing part and a hydrogen seal that separates the first housing part from the interior of the second housing part.

The quick pressure relief device includes a quick discharge line for relieving pressure from the first housing part upon a failure of the hydrogen seal, and a bleed line fluidically connected to the quick discharge line and to the interior of the second housing part. | ||||||
| 159 | Method for inerting a generator in a power station | US268272 | 1999-03-15 | US6076568A | 2000-06-20 | Helmut Rehm; Klaus Weller; Christoph Lehmann |
| A method for inerting a generator in a power station includes flushing the generator in a rapid manner which is favorable in terms of power consumption and is simplified in terms of process technology. Cooling gas which is present in the working state for cooling in the generator is displaced through the use of an inert gas stored in gaseous form, in particular argon. A phase transition from, for example, a liquid to a gaseous inert gas, which prolongs the inerting operation and consumes large amounts of power, can thus be dispensed with. The supply of inert gas can easily be monitored by pressure measurement. | ||||||
| 160 | Measurement of hydrogen leakage through stator windings into generator coolant water and oxygenation of the coolant water | US329737 | 1994-10-26 | US5492004A | 1996-02-20 | Hans E. Berg; Lawrence E. Jordan |
| Hydrogen leakage from a generator core through stator windings into the generator coolant water is measured by flowing air into the coolant water exiting the stator windings and measuring the hydrogen content of the gas vented from a coolant water reservoir. The flow of air into the coolant water also oxygenates the coolant water to prevent undesirable formation of less stable cuprous oxide layers and enhance the formation of a protective cupric oxide film on the inside surfaces of the copper stator windings. In another form, trace gas is introduced into one of the generator core environment and the coolant water and a detector measures the magnitude of the trace gas leaked between the generator core environment and the coolant water as an indication of the magnitude of hydrogen leakage escaping from the generator core into the stator water coolant system. | ||||||
