Cov chaw tsim hluav taws xob hauv dej tsis yog tsuas yog siv cov turbines thiab generators xwb - kev ua haujlwm ruaj khov, muaj kev nyab xeeb, thiab ua haujlwm tau zoo nyob ntawm kev ua haujlwm ntawm cov tshuab tswj hluav taws xob. Ntawm cov no, lub txee tswj hwm switchgear ua lub luag haujlwm tseem ceeb hauv kev tswj hwm thiab tiv thaiv cov khoom siv hydropower.
Lub txee tswj hwm switchgear hauv lub chaw tsim hluav taws xob hydropower yog tsim los tswj, saib xyuas, thiab tiv thaiv cov khoom siv hluav taws xob tseem ceeb xws li cov generators, transformers, thiab cov txheej txheem pabcuam. Nws koom ua ke cov khoom siv hloov pauv, cov relays tiv thaiv, cov cuab yeej ntsuas, thiab cov chav tswj hwm rau hauv ib qho qauv me me thiab teeb tsa zoo. Qhov no ua kom ntseeg tau tias kev faib hluav taws xob hauv lub Hoobkas tseem ntseeg tau thiab ruaj ntseg nyob rau hauv ntau yam kev ua haujlwm.
Ib qho ntawm cov haujlwm tseem ceeb ntawm lub txee tswj hwm yog los muab kev ua haujlwm hloov pauv kom muaj kev nyab xeeb. Nws tso cai rau cov neeg teb xov tooj pib lossis nres cov khoom siv, cais cov seem uas tsis zoo, thiab tswj kev faib khoom kom zoo. Tsis tas li ntawd, cov txheej txheem tiv thaiv siab heev tau muab tso rau hauv kom pom cov teeb meem xws li overload, luv Circuit, lossis voltage hloov pauv. Thaum pom qhov txhaum, lub kaw lus tuaj yeem txiav tawm lub voj voog cuam tshuam sai sai, tiv thaiv kev puas tsuaj rau cov khoom siv kim thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
Cov txee hluav taws xob hydropower niaj hnub no tau nruab nrog cov txheej txheem tswj hwm ntse. Cov no suav nrog cov programmable logic controllers (PLC), digital protection relays, thiab kev saib xyuas deb. Nrog cov thev naus laus zis no, cov neeg ua haujlwm tuaj yeem saib xyuas cov ntaub ntawv tiag tiag xws li voltage, tam sim no, zaus, thiab lub zog tso tawm, tsis hais nyob rau ntawm qhov chaw lossis los ntawm cov kab ke SCADA deb. Qhov no tsis yog tsuas yog txhim kho kev ua haujlwm zoo xwb tab sis kuj ua rau muaj kev saib xyuas kwv yees thiab txo lub sijhawm tsis ua haujlwm.
Lwm qhov zoo tseem ceeb ntawm cov txee tswj hwm zoo yog lawv qhov kev hloov pauv tau yooj yim. Txawm hais tias rau cov chaw tsim hluav taws xob me me lossis cov chaw nres tsheb loj, cov tshuab hloov pauv tuaj yeem hloov kho kom ua tau raws li cov kev cai tshwj xeeb, cov xwm txheej ib puag ncig, thiab cov qauv grid. Cov ntaub ntawv zoo thiab cov qauv tsim vaj tsev ruaj khov kuj ua kom muaj kev ua haujlwm zoo hauv cov chaw ib puag ncig hnyav, suav nrog cov av noo siab thiab qhov kub thiab txias sib txawv uas pom ntau hauv cov chaw tsim hluav taws xob.
Xaus lus, lub txee tswj hwm switchgear yog ib qho tseem ceeb ntawm cov kab ke hydropower. Los ntawm kev ua kom muaj kev tswj hwm meej, kev tiv thaiv tag nrho, thiab kev saib xyuas ntse, nws pab txhawb rau kev nyab xeeb, kev ua haujlwm zoo, thiab lub neej ntev ntawm cov khoom siv hydropower. Raws li qhov kev thov rau lub zog huv thiab rov ua dua tshiab txuas ntxiv mus, cov kev daws teeb meem tswj hwm hluav taws xob siab heev yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo dua ntawm kev tsim hluav taws xob hydropower.
