Description
Technical field
The utility model is related to Water of Power Plant hydrogen hydrogen cooled generator system, and in particular to the stator cooling water in generator system
Case nitrogen charging and the row's of vacuumizing hydrogen production device.
Background technology
Water hydrogen hydrogen cooled generator system is normally in operation, and the operating pressure of hydrogen is higher than the fortune of stator cooling water in generator
Row pressure, always has micro hydrogen slightly to be leaked into by the bar of polytetrafluoroethyltubing tubing matter in Stator Condense Water System,
Hydrogen flows back into stator cooling water case with stator cooling water, slowly gathers to stator cooling water case.
Changed by water temperature because of stator cooling water case, backwater dilatation, the factor such as anti-siphonage pipe connection and water-level fluctuation
Influence, a kind of unstable state in pressure-fired or negative pressure, hydrogen can not be suitable by the hydrogen discharging pipe of stator cooling water box top
Sharp is emitted into air.
If during the density of hydrogen over-limit condition gathered for a long time inside stator cooling water case, there is hydrogen in stator cooling water case
The risk of blast；Stator cooling water box top is equiped with a set of leakage hydrogen detector, the dead angle of hydrogen discharging pipe and the detector sampling of leakage hydrogen
Easily gather hydrogen at pipe, cause the measured value for leaking hydrogen detector to lose representativeness.
The content of the invention
The purpose of this utility model is to provide a kind of stator cooling water case nitrogen charging and the row's of vacuumizing hydrogen production device, improved Lou
The authenticity of hydrogen detector measurement, judges that the operating condition of generator provides real parameter foundation for power plant.
To reach the purpose, the technical solution of the utility model is：A kind of stator cooling water case nitrogen charging and the row's of vacuumizing hydrogen
Device, it is characterised in that：A set of nitrogen charging device is set in the offside of stator cooling water case hydrogen discharging pipe, set on nitrogen charging device pipeline
Put nitrogen charging pressure-reducing valve and isolating valve；Draw at stator cooling water case hydrogen discharging pipe and connect a stainless steel tubule to small machine and vacuumize mother
Pipe, sets on stainless steel tubule and vacuumizes isolating valve.
The utility model stator cooling water case periodically passes through nitrogen charging and the row's of vacuumizing hydrogen production device, it is ensured that stator cooling water case
Hydrogen content at internal, hydrogen discharging pipe dead angle and leakage hydrogen detector probe tube meets relevant criterion；Improve Lou hydrogen detector survey
The authenticity of amount, judges that the operating condition of generator provides real parameter foundation for power plant.
