Cov txhuam carbon Morteng grounding yog cov khoom tseem ceeb hauv cov motors tig (xws li cov generators thiab cov motors hluav taws xob), feem ntau yog siv los tshem tawm cov tam sim no, tiv thaiv kev nyab xeeb ntawm cov khoom siv, thiab pab saib xyuas cov txheej txheem. Lawv cov xwm txheej siv thiab cov haujlwm yog raws li nram no:
I. Cov Haujlwm Tseem Ceeb thiab Cov Txiaj Ntsig
- Thaum lub tshuab hluav taws xob lossis lub cev muaj zog khiav, qhov tsis sib xws hauv lub zog sib nqus (xws li qhov sib txawv ntawm huab cua tsis sib xws lossis qhov sib txawv ntawm lub kauj impedance) tuaj yeem ua rau lub zog hluav taws xob ntawm lub ncej tig. Yog tias lub zog hluav taws xob ntawm lub ncej tawg los ntawm cov roj hmab, nws tuaj yeem tsim cov hluav taws xob ntawm lub ncej, ua rau lub ncej electrolysis, lubrication degradation, thiab txawm tias lub cev muaj zog tsis ua haujlwm.
- Cov txhuam carbon uas siv av hauv Morteng ua rau lub rotor shaft luv luv mus rau lub tshuab, ua rau cov hluav taws xob ntawm lub shaft mus rau hauv av thiab tiv thaiv lawv kom tsis txhob ntws los ntawm cov bearings. Piv txwv li, cov generators loj feem ntau ntsia cov txhuam carbon uas siv av rau ntawm qhov kawg ntawm turbine, thaum cov bearings kawg ntawm excitation tau nruab nrog cov ntaub qhwv rwb thaiv tsev, tsim cov qauv 'excitation end insulation + turbine end grounding'.
II. Cov Xwm Txheej Siv Ib Txwm Muaj
-Cov tshuab hluav taws xob cua sov/hydropower: Cov txhuam carbon Morteng grounding tau teeb tsa rau ntawm qhov kawg ntawm lub turbine, ua ke nrog cov bearings insulated ntawm qhov kawg excitation, kom tshem tawm qhov xau magnetic induction shaft voltage. Piv txwv li, hauv cov tshuab hluav taws xob hydropower, thrust bearings tsuas yog siv cov roj nyias nyias rau kev rwb thaiv tsev, thiab grounding cov txhuam carbon tuaj yeem tiv thaiv electrolysis ntawm cov plhaub bearing.
-Cov cua tshuab: Siv rau cov rotors generator lossis cov tshuab tiv thaiv kev poob siab, cov ntaub ntawv feem ntau yog xaiv los ntawm cov hlau graphite (tooj liab / nyiaj-raws li), uas muaj kev coj ua siab, tiv taus kev hnav, thiab tiv taus tam sim no ib ntus.
-Lub cev muaj zog siab/hloov pauv zaus: Cov no muaj kev pheej hmoo siab dua ntawm cov hluav taws xob ntawm lub ncej. Piv txwv li, Tonghua Power Generation Company tau teeb tsa cov txhuam carbon uas muaj av rau ntawm qhov kawg ntawm lub cev muaj zog kiv cua tseem ceeb, siv cov caij nplooj ntoos hlav uas muaj zog tas li kom tswj tau xoom lub zog, yog li daws qhov teeb meem uas cov kabmob insulated thawj zaug tsis tuaj yeem thaiv cov hluav taws xob ntawm lub ncej tag nrho.
-Kev thauj mus los ntawm tsheb ciav hlau: Hauv cov cav traction ntawm cov tsheb ciav hlau hluav taws xob lossis cov tsheb ciav hlau diesel, cov txhuam carbon uas tau sib tsoo hauv av tshem tawm cov hluav taws xob zoo li qub thaum lub sijhawm ua haujlwm, tiv thaiv cov kabmob, thiab tswj kev ruaj khov ntawm lub cev hluav taws xob.
