Cov Kev Ntsuas ntawm Cov Txhuam Carbon Sib Tw thiab Cov Cheebtsam Tuav Txhuam
Yuav kom phim cov kev xav tau ntawm lub tshuab hluav taws xob no, peb tau muab cov txhuam carbon thiab cov khoom siv tuav txhuam nrog cov qhov loj me raws li hauv qab no:
| Lub Npe ntawm Cov Khoom | Dav (hli) | Qhov tuab (hli) | Qhov siab (hli) | Cov Lus Cim |
| Lub thawv txhuam | 159 | 84 | 143 | - |
| Kev Txhawb Nqa Txhuam | 90 | 32 | 192 | - |
| Txhuam (NCC-634) | 25.4 | 38.1 | 102 | Qhov ntev seem ntawm qhov txwv hnav: 45 hli |
Lub txhuam carbon (NCC-634) yog ib qho tseem ceeb hauv lub kaw lus excitation. Nws yog tsim los kom tswj tau qhov kev sib cuag hluav taws xob ruaj khov nyob rau hauv qhov kev sib hloov ceev ceev ntawm 3,000 rpm thiab qhov tam sim no siab ntawm 2,760 A, kom ntseeg tau tias kev xa cov tam sim no excitation zoo.
Cov txhuam carbon no yog ib qho hloov ncaj qha rau Morgan NCC-634 (kuj hloov tau nrog Mersen LFC554). Nws tau raug kuaj xyuas thiab txheeb xyuas kom xa tau qhov sib npaug, thiab qee zaum zoo dua, kev ua haujlwm xa hluav taws xob, suav nrog kev sib phim resistivity, kev sib cuag voltage poob, thiab cov yam ntxwv hnav. Nws ua kom ntseeg tau tias kev hloov pauv tam sim no txhim khu kev qha, txawm tias nyob rau hauv qhov ceev ceev thiab tam sim no ntawm lub tshuab hluav taws xob hydrogen-txias 245,800 kVA no, muab kev xaiv pheej yig thiab ua tau zoo rau kev saib xyuas thiab hloov kho lub zog fais fab.
Daim Ntawv Thov Khoom thiab Kev Ua Tau Zoo
Cov txhuam carbon brush blocks (NCC-634) uas muab los no yog tsim tshwj xeeb rau cov tshuab hluav taws xob loj uas ua haujlwm hauv cov chaw nyuaj. Cov txiaj ntsig tseem ceeb suav nrog:
- Kev Ua Hluav Taws Xob Zoo heev: Xyuas kom muaj kev tiv thaiv kev sib cuag tsawg kawg nkaus thiab qhov hluav taws xob poob qis, txo qhov poob zog.
- Kev Tiv Thaiv Kev Hnav Zoo Tshaj Plaws: Ua kom lub neej ua haujlwm ntev dua thiab txo qhov zaus txij nkawm, txawm tias nyob rau hauv qhov xwm txheej tam sim no siab thiab ceev ceev.
- Kev Tiv Thaiv Kev Cob Qhia Zoo Tshaj Plaws: Tswj kev ua haujlwm sib cuag ruaj khov, tiv thaiv kev kub hnyiab thiab kev ua tsis tiav ua ntej lub sijhawm ua haujlwm.
- Kev Haum Xeeb: Qhov ntev tau phim meej rau cov khoom siv txhuam qub, ua kom ntseeg tau tias kev teeb tsa tsis muaj teeb meem thiab kev ua haujlwm zoo tshaj plaws.
Cov yam ntxwv no yog qhov tseem ceeb rau kev ua haujlwm mus sij hawm ntev, ua haujlwm tau zoo, thiab muaj kev nyab xeeb ntawm lub tshuab hluav taws xob hydrogen-txias 245,800 kVA, uas ua lub luag haujlwm tseem ceeb hauv lub Hoobkas tsim hluav taws xob.
Duab ntawm Cov Txhuam Carbon Sib Xws
Peb cog lus tias yuav muab cov khoom siv txhawb nqa tseem ceeb rau kev lag luam fais fab thoob ntiaj teb, pab cov tshuab hluav taws xob ua haujlwm tau zoo, ruaj khov, thiab ua haujlwm tau ntev. Peb qhov kev txawj ntse hauv kev siv tshuab txhuam carbon ua kom peb tuaj yeem muab cov kev daws teeb meem uas ua tau raws li qhov yuav tsum tau ua kom nruj tshaj plaws, txawm tias rau cov khoom siv qub xws li lub tshuab hluav taws xob hydrogen-txias xyoo 1984 no.
