Feem ntau, ib lub tshuab hluav taws xob muaj ib lub cav, lub tshuab hluav taws xob, lub kaw lus tswj hwm tag nrho, lub kaw lus roj, thiab lub kaw lus faib hluav taws xob. Lub zog ntawm lub tshuab hluav taws xob hauv lub kaw lus sib txuas lus - lub cav diesel lossis lub cav roj turbine - yeej zoo ib yam rau cov chav siab thiab qis; Qhov kev teeb tsa thiab roj ntawm lub kaw lus roj feem ntau yog cuam tshuam nrog lub zog, yog li tsis muaj qhov sib txawv tseem ceeb ntawm cov chav siab thiab qis, yog li tsis muaj qhov sib txawv ntawm qhov yuav tsum tau rau cov cua nkag thiab cov pa tawm ntawm cov chav uas muab cua txias. Qhov sib txawv ntawm cov kev teeb tsa thiab kev ua tau zoo ntawm cov tshuab hluav taws xob siab thiab cov tshuab hluav taws xob qis feem ntau pom tseeb hauv lub tshuab hluav taws xob thiab lub kaw lus faib khoom.
1. Qhov sib txawv ntawm qhov ntim thiab qhov hnyav
Cov khoom siv hluav taws xob siab siv cov khoom siv hluav taws xob siab, thiab qhov nce ntawm qib hluav taws xob ua rau lawv cov kev xav tau rwb thaiv tsev siab dua. Ib yam li ntawd, qhov ntim thiab qhov hnyav ntawm cov khoom siv hluav taws xob loj dua li cov khoom siv hluav taws xob qis. Yog li ntawd, tag nrho lub cev ntim thiab qhov hnyav ntawm 10kV cov khoom siv hluav taws xob loj dua me ntsis dua li cov khoom siv hluav taws xob qis. Tsis muaj qhov sib txawv tseem ceeb hauv qhov tsos tsuas yog cov khoom siv hluav taws xob xwb.
2. Qhov sib txawv ntawm cov txheej txheem grounding
Cov txheej txheem av nruab nrab ntawm ob lub tshuab hluav taws xob sib txawv. Lub tshuab hluav taws xob 380V yog txuas nrog lub hnub qub. Feem ntau, lub kaw lus qis-voltage yog lub kaw lus av nruab nrab ncaj qha, yog li lub hnub qub txuas nrog lub hnub qub nruab nrab ntawm lub tshuab hluav taws xob tau teeb tsa kom rub tawm thiab tuaj yeem av ncaj qha thaum xav tau. 10kV system yog lub kaw lus av me me tam sim no, thiab lub ntsiab lus nruab nrab feem ntau tsis tau av lossis av los ntawm kev tiv thaiv av. Yog li ntawd, piv rau cov chav tsev qis-voltage, 10kV chav tsev xav tau ntxiv cov khoom siv faib tawm nruab nrab xws li cov txee tiv thaiv thiab cov txee contactor.
3. Qhov sib txawv ntawm cov txheej txheem tiv thaiv
Feem ntau cov tshuab hluav taws xob muaj zog siab xav tau kev teeb tsa kev tiv thaiv tam sim no sai, kev tiv thaiv overload, kev tiv thaiv grounding, thiab lwm yam. Thaum qhov rhiab heev ntawm kev tiv thaiv tam sim no sai tsis ua raws li qhov yuav tsum tau ua, kev tiv thaiv sib txawv longitudinal tuaj yeem teeb tsa.
Thaum muaj qhov teeb meem grounding tshwm sim hauv kev ua haujlwm ntawm lub tshuab hluav taws xob muaj zog siab, nws ua rau muaj kev phom sij rau cov neeg ua haujlwm thiab cov khoom siv, yog li nws yog qhov tsim nyog los teeb tsa kev tiv thaiv qhov teeb meem grounding.
Lub ntsiab lus nruab nrab ntawm lub tshuab hluav taws xob yog grounded los ntawm lub resistor. Thaum muaj qhov txhaum grounding ib theem tshwm sim, qhov txhaum tam sim no ntws los ntawm qhov nruab nrab tuaj yeem pom, thiab kev tiv thaiv tripping lossis kaw tuaj yeem ua tiav los ntawm kev tiv thaiv relay. Lub ntsiab lus nruab nrab ntawm lub tshuab hluav taws xob yog grounded los ntawm lub resistor, uas tuaj yeem txwv qhov txhaum tam sim no hauv qhov nkhaus puas tsuaj ntawm lub tshuab hluav taws xob, thiab lub tshuab hluav taws xob tuaj yeem ua haujlwm nrog qhov txhaum. Los ntawm kev tiv thaiv grounding, qhov txhaum grounding tuaj yeem pom zoo thiab kev ua haujlwm tiv thaiv relay tuaj yeem tsav. Piv rau cov chav tsev qis-voltage, cov khoom siv hluav taws xob siab xav tau ntxiv cov khoom siv faib cov ntsiab lus nruab nrab xws li cov txee tiv thaiv thiab cov txee contactor.
Yog tias tsim nyog, kev tiv thaiv sib txawv yuav tsum tau teeb tsa rau cov khoom siv hluav taws xob siab.
Muab kev tiv thaiv qhov sib txawv ntawm peb theem tam sim no ntawm lub stator winding ntawm lub generator. Los ntawm kev teeb tsa cov transformers tam sim no ntawm ob lub davhlau ya nyob twg ntawm txhua lub kauj hauv lub generator, qhov sib txawv ntawm tam sim no ntawm cov davhlau ya nyob twg nkag thiab tawm ntawm lub kauj raug ntsuas los txiav txim siab qhov xwm txheej rwb thaiv tsev ntawm lub kauj. Thaum muaj luv luv Circuit Court lossis av hauv ob lossis peb theem, qhov txhaum tam sim no tuaj yeem pom hauv ob lub transformers, yog li tsav tsheb tiv thaiv.
4. Qhov sib txawv ntawm cov cables tso zis
Nyob rau hauv tib theem peev xwm, lub qhov hluav taws xob cable txoj kab uas hla ntawm cov chav tsev siab-voltage yog me dua li ntawm cov chav tsev qis-voltage, yog li qhov chaw xav tau rau cov channel qhov hluav taws xob qis dua.
5. Qhov sib txawv ntawm Cov Txheej Txheem Tswj Xyuas Chav
Lub kaw lus tswj hwm ntawm cov chav hluav taws xob qis feem ntau tuaj yeem koom ua ke rau ib sab ntawm lub tshuab hluav taws xob ntawm lub cev tshuab, thaum cov chav hluav taws xob siab feem ntau xav tau lub thawv tswj hwm chav ywj pheej kom teeb tsa cais ntawm chav vim muaj teeb meem cuam tshuam teeb liab.
6. Qhov sib txawv ntawm cov kev cai saib xyuas
Cov kev cai saib xyuas rau cov tshuab hluav taws xob muaj zog siab hauv ntau yam xws li lub kaw lus roj thiab lub tshuab nqus cua thiab tso pa tawm zoo ib yam li cov tshuab hluav taws xob qis, tab sis kev faib hluav taws xob ntawm cov tshuab yog lub kaw lus hluav taws xob siab, thiab cov neeg ua haujlwm saib xyuas yuav tsum muaj daim ntawv tso cai ua haujlwm hluav taws xob siab.
