Lub tshuab hluav taws xob feem ntau muaj lub tshuab hluav taws xob, lub tshuab hluav taws xob, kev tswj hwm kev tswj hwm, roj hluav taws xob hluav taws xob, thiab lub zog faib hluav taws xob.Lub hwj chim ib feem ntawm lub tshuab hluav taws xob tau teeb tsa hauv kev sib txuas lus - lub cav diesel lossis roj turbine cav - yog qhov pib zoo ib yam rau cov chav ua haujlwm siab thiab tsis tshua muaj siab;Kev teeb tsa thiab cov roj ntim ntawm cov roj system feem ntau cuam tshuam nrog lub zog, yog li tsis muaj qhov sib txawv ntawm qhov siab thiab qis siab, yog li tsis muaj qhov sib txawv ntawm qhov yuav tsum tau ua rau cov cua nkag thiab tso tawm ntawm cov chav tsev uas muab cua txias.Qhov sib txawv ntawm qhov tsis sib xws thiab kev ua haujlwm ntawm high-voltage generator sets thiab low-voltage generator sets are mainly reflected in the generator part and distribution system part.
1. Qhov txawv ntawm qhov ntim thiab qhov hnyav
High voltage generator sets siv high-voltage generators, thiab qhov nce nyob rau hauv voltage theem ua rau lawv cov rwb thaiv tsev yuav tsum siab dua.Raws li qhov tshwm sim, qhov ntim thiab qhov hnyav ntawm lub tshuab hluav taws xob yog qhov loj dua li cov khoom siv hluav taws xob tsawg.Yog li ntawd, tag nrho lub cev ntim thiab qhov hnyav ntawm 10kV generator teeb yog me ntsis loj dua li cov chav tsev uas tsis muaj hluav taws xob.Tsis muaj qhov sib txawv tseem ceeb hauv qhov tsos tshwj tsis yog rau lub tshuab hluav taws xob.
2. Qhov sib txawv ntawm txoj kev hauv av
Qhov nruab nrab grounding txoj kev ntawm ob lub tshuab hluav taws xob teeb sib txawv.Lub 380V chav tsev winding yog lub hnub qub txuas nrog.Feem ntau, qhov qis-voltage system yog qhov nruab nrab qhov nruab nrab qhov nruab nrab qhov nruab nrab qhov nruab nrab, yog li lub hnub qub txuas nrog nruab nrab ntawm lub tshuab hluav taws xob tau teeb tsa kom tshem tau thiab tuaj yeem ncaj qha hauv av thaum xav tau.10kV system yog ib qho me me hauv av tam sim no, thiab qhov nruab nrab ntawm qhov nruab nrab feem ntau tsis yog av lossis av los ntawm kev tiv thaiv hauv av.Yog li ntawd, piv rau cov chav nyob uas tsis tshua muaj hluav taws xob, 10kV chav nyob yuav tsum tau ntxiv cov khoom siv nruab nrab ntawm cov khoom siv xws li cov khoom siv hluav taws xob thiab cov khoom siv contactor.
3. Qhov txawv ntawm txoj kev tiv thaiv
High voltage generator sets feem ntau xav tau lub installation ntawm tam sim no ceev break tiv thaiv, overload tiv thaiv, grounding tiv thaiv, thiab lwm yam. Thaum lub rhiab heev ntawm tam sim no ceev so tiv thaiv tsis tau raws li qhov yuav tsum tau, longitudinal sib txawv tiv thaiv yuav ntsia tau.
Thaum muaj teeb meem hauv av tshwm sim hauv kev ua haujlwm ntawm lub tshuab hluav taws xob high-voltage teeb, nws ua rau muaj kev nyab xeeb tseem ceeb rau cov neeg ua haujlwm thiab cov khoom siv, yog li nws yuav tsum tau teeb tsa kev tiv thaiv kev tiv thaiv hauv av.
Qhov nruab nrab point ntawm lub tshuab hluav taws xob yog grounded los ntawm ib tug resistor.Thaum ib qho kev txhaum hauv av ib zaug tshwm sim, qhov txhaum tam sim no ntws los ntawm qhov nruab nrab tuaj yeem raug kuaj pom, thiab kev tiv thaiv kev tawm mus los yog 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 nyob rau hauv qhov kev tso cai ntawm kev puas tsuaj ntawm lub tshuab hluav taws xob, thiab lub tshuab hluav taws xob tuaj yeem ua haujlwm nrog qhov tsis raug.Los ntawm kev tiv thaiv hauv av, kev ua txhaum hauv av tuaj yeem tshawb pom tau zoo thiab kev tiv thaiv kev tiv thaiv tuaj yeem raug tsav.Piv nrog rau cov chav nyob uas tsis tshua muaj hluav taws xob, cov khoom siv hluav taws xob high-voltage yuav tsum muaj qhov sib ntxiv ntawm cov khoom siv nruab nrab ntawm cov khoom siv xws li cov khoom siv hluav taws xob thiab cov khoom siv contactor.
Yog tias tsim nyog, kev tiv thaiv kev sib txawv yuav tsum tau teeb tsa rau cov khoom siv hluav taws xob high-voltage.
Muab peb-theem tam sim no sib txawv tiv thaiv ntawm stator winding ntawm lub tshuab hluav taws xob.Los ntawm kev txhim kho tam sim no transformers ntawm ob lub outgoing terminals ntawm txhua lub kauj hauv lub tshuab hluav taws xob, qhov sib txawv tam sim no ntawm cov khoom nkag thiab tawm ntawm lub kauj yog ntsuas los txiav txim qhov xwm txheej rwb thaiv tsev ntawm lub kauj.Thaum ib qho luv luv Circuit Court lossis grounding tshwm sim hauv ob lossis peb theem, qhov txhaum tam sim no tuaj yeem kuaj pom hauv ob qho tib si transformers, yog li tsav kev tiv thaiv.
4. Qhov sib txawv ntawm cov zis cables
Nyob rau hauv tib lub peev xwm, lub qhov hluav taws xob cable txoj kab uas hla ntawm high-voltage units yog npaum li cas me dua li ntawm tsawg-voltage units, yog li ntawd qhov chaw ua hauj lwm yuav tsum tau rau qhov hluav taws xob channel yog tsawg.
5. Qhov sib txawv ntawm Cov Txheej Txheem Tswjhwm
Lub tsev tswj qhov system ntawm cov chav nyob uas tsis tshua muaj hluav taws xob feem ntau tuaj yeem ua ke ntawm ib sab ntawm lub tshuab hluav taws xob seem ntawm lub tshuab lub cev, thaum cov khoom siv hluav taws xob siab feem ntau xav tau lub thawv tswj kev ywj pheej uas yuav tsum tau muab cais tawm ntawm chav tsev vim muaj teeb meem cuam tshuam.
6. Qhov sib txawv ntawm kev saib xyuas
Kev saib xyuas yuav tsum tau ua rau cov tshuab hluav taws xob muaj hluav taws xob ntau hauv ntau yam xws li cov roj hluav taws xob hluav taws xob thiab cov cua nkag thiab cov pa tawm yog sib npaug rau cov khoom siv hluav taws xob tsawg, tab sis cov hluav taws xob faib hluav taws xob ntawm cov chav nyob yog lub zog siab, thiab cov neeg ua haujlwm tu. yuav tsum tau nruab nrog high-voltage daim ntawv tso cai ua hauj lwm.
