Description
Technical field
The present invention relates to thermal power plant's electromotor fills row's hydrogen process, a kind of more particularly, to thermal power plant electromotor fills row hydrogen system automatically
System.
Background technology
In Turbo-generator Set running, when generator transforms mechanical energy into electricity energy, inevitably result from
Energy loss, the energy of these losses finally all becomes heat energy, leads to each part temperatures such as rotor, stator of electromotor to raise.
In order to derive this partial heat, need with cooling medium, electromotor to be carried out forcing cooling.The electromotor cooling commonly used at present
Mode is free air cooling, water cooling and hydrogen_cooling.Because hydrogen pyroconductivity is 7 times of air, hydrogen_cooling efficiency is more empty
Cold and water-cooled is all high, so 200MW and above capacity unit employ the Water hydrogen type of cooling mostly, that is, 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 electromotor, then replaces the carbon dioxide in electromotor with air；After unit maintenance terminates, need to be put with carbon dioxide
Change the air in motor, then use the carbon dioxide in hydrogen exchange electromotor.Due to being stored in steel cylinder（Capacity is less）In
Carbon dioxide be liquid, in replacement process occur vaporization heat absorption, steel cylinder can freeze, and needs operations staff constantly to spray water
Thaw, after steel cylinder freezes, carbon dioxide tends not to be fully utilized, lead to waste.System pressure control is needed in replacement process
System is stable, originally simply by controlling outlet hand-operated valve to adjust system pressure, leads to operating pressure unstable, thus affecting 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
Need two replacement process, and the switching of sample examination, system, change carbon dioxide steel cylinder and be required to manually carry out it is clear that this
Fill（Row）The workload of hydrogen process is larger and there is certain error, thus it is longer to lead to fill row's hydrogen process, finally affects machine
Group overall startup or maintenance process.
The Chinese utility model patent of Patent No. ZL201420283938.4 discloses a kind of carbon dioxide heating
Device, main frame front is provided with electric-controlled plate, and the main frame back side is provided with and off switch, fusible core and supply socket, and main frame both sides arrange air inlet
Mouth and gas outlet, air inlet and gas outlet connect main frame internal heater by pipeline, and heater arranges relief valve, connect air inlet
Sensor holder is arranged on the pipeline of mouth.The gas outlet of device is connected with gas control station air inlet by pipeline, the air inlet of device
Mouth is connected with carbon dioxide bus-bar gas outlet by pipeline；The carbon dioxide that less than -20 DEG C can be made is brought rapidly up
To 0～45 DEG C, the arbitrarily adjustment between 0～45 DEG C of output gas temperature sets, thus efficiently against electromotor gas displacement
When suddenly cold and hot phenomenon, prevent from condensing and condense, prevent insulation ag(e)ing it is ensured that the work efficiency of electromotor.This utility model
Although being related to one of electromotor gas displacement work process carbon dioxide heater, this utility model does not solve
Certainly following technological deficiency present in prior art, that is,：Due to filling every time（Row）Hydrogen process is required to two replacement process, and takes
Sample chemical examination, system switching, replacing carbon dioxide steel cylinder are required to manually carry out it is clear that this fill（Row）The workload of hydrogen process is relatively
Big and there is certain error, thus it is longer to lead to fill row's hydrogen process, final impact unit overall startup or maintenance process.Cause
This is it would be highly desirable to improve.
