Description
Technical field
Row's hydrogen process more particularly to a kind of thermal power plant's generator, which are filled, the present invention relates to thermal power plant's generator fills row hydrogen system automatically
System.
Background technique
In Turbo-generator Set operational process, when generator transforms mechanical energy into electricity energy, inevitably result from
The energy of energy loss, these losses finally all becomes thermal energy, and each part temperatures such as rotor, stator of generator is caused to increase.
In order to export this partial heat, need to carry out pressure cooling to generator with cooling medium.Currently used generator is cooling
Mode is free air cooling, water cooling and hydrogen_cooling.Since hydrogen pyroconductivity is 7 times of air, hydrogen_cooling efficiency is more empty
Cold and water cooling is all high, so 200MW and the above capacity unit use the Water hydrogen type of cooling mostly, i.e., in stator winding water
Cold, rotor windings internal hydrogen cooling, iron core and end construction part hydrogen outer cooling.Before Steam Turbine maintenance, need to use carbon dioxide replacement
The hydrogen of generator, then with the carbon dioxide in air displacement generator；After unit maintenance, need to be set with carbon dioxide
The air in motor is changed, then with the carbon dioxide in hydrogen displacement generator.Due to being stored in steel cylinder (capacity is smaller)
Carbon dioxide be liquid, vaporization heat absorption occurs in replacement process, steel cylinder can freeze, and operations staff is needed constantly to spray water
It thaws, carbon dioxide tends not to be fully utilized after steel cylinder freezes, and causes to waste.System pressure control is needed in replacement process
System is stablized, and adjusted system pressure simply by control outlet hand-operated valve originally, and caused operating pressure unstable, to influence close
Oil sealing pressure, sealing mailbox oil level are unstable, and operations staff's monitoring, operating pressure are larger.Additionally, due to filling every time, (row) hydrogen process is equal
Two replacement process are needed, and the switching of sample examination, system, replacement carbon dioxide steel cylinder are required to manually carry out, it is clear that this
Fill (row) hydrogen process larger workload and there is a certain error, thus will lead to fill row hydrogen process it is longer, finally influence machine
Group overall startup or maintenance process.
The Chinese utility model patent of Patent No. ZL201420283938.4 discloses a kind of carbon dioxide gas heating
Device, host front are equipped with electric-controlled plate, and the host back side is equipped with power switch, fusible core and power outlet, and air inlet is arranged in host two sides
Mouth and gas outlet, air inlet and air outlet connect host internal heater by pipeline, safety valve are arranged on heater, connect air inlet
Sensor holder is set on the pipeline of mouth.The gas outlet of device is connect by pipeline with gas control station air inlet, the air inlet of device
Mouth is connect by pipeline with carbon dioxide gas busbar connector gas outlet；- 20 DEG C of carbon dioxide gas below can be made to be brought rapidly up
To 0~45 DEG C, arbitrarily adjustment is set output gas temperature between 0~45 DEG C, thus efficiently against generator gas displacement
When suddenly cold and hot phenomenon, prevent condense and condense, prevent insulation ag(e)ing, guarantee the working efficiency of generator.The utility model
Although being related to one of generator gas displacement course of work carbon dioxide gas heating device, which is not solved
Following technological deficiency certainly existing in the prior art, it may be assumed that be required to two replacement process due to filling (row) hydrogen process every time, and take
Sample chemical examination, system switching, replacement carbon dioxide steel cylinder is required to manually carry out, it is clear that this workload for filling (row) hydrogen process compared with
Big and there is a certain error, to will lead to, to fill row's hydrogen process longer, final to influence unit overall startup or maintenance process.Cause
This, it would be highly desirable to it improves.

Start to be flushed with hydrogen gas row's carbon dioxide to generator hydrogen cooling system (2)；
Step 3: when gas concentration analyzer (5) detects that the density of hydrogen of generator hydrogen cooling system (2) reaches 96%
When, the row's of being automatically closed carbon dioxide main valve (10), bleed pressure regulator (15), Hydrogen Vapor Pressure is promoted to service pressure
Afterwards, it is automatically closed and is flushed with hydrogen solenoid valve (6), the gas displacement in generator hydrogen cooling system (2) finishes.
