Qhuav -}}} hom transformers yog cov khoom siv hluav taws xob hauv hluav taws xob. Kev ua haujlwm kom raug ncaj qha cuam tshuam lawv txoj kev ua haujlwm nyab xeeb thiab kev pabcuam lub neej. Cov ntsiab lus hauv qab no lub qhuav- hom kev ua haujlwm transformer thiab kev ceev faj.
I. Ua ntej - commressioning kev kuaj xyuas
Ua ntej kev ua haujlwm ib qhuav -} hom kev soj ntsuam, yuav tsum muaj kev soj ntsuam ntau dua los xyuas kom cov khoom siv tau zoo. Ua ntej tshaj tawm, soj ntsuam tus hloov pauv sab nrauv rau kev puas tsuaj, cov cim ntawm kev tawm, lossis tsis muaj suab nrov. Thib ob, paub meej tias lub tshuab txias txias (xws li tus kiv cua) ua haujlwm tau zoo thiab cov vents yog unobstructed. Thib peb, xyuas tias txhua lub terminals muaj kev ruaj ntseg nrawm thiab tias cov rwb thaiv tsev tsis muaj hnub nyoog lossis puas. Thaum kawg, txheeb xyuas qhov ntsuas hluav taws xob ntais ntawv cov kab ke thiab cov cuab yeej tiv thaiv (xws li kev tiv thaiv kub thiab kev tiv thaiv ntau dhau los.
Ii. Hwj huam -} ntawm kev ua haujlwm
Pre6 -}} kaw cov kev npaj: xyuas kom tus hloov pauv hloov pauv thiab cov Circuit Court breaker yog nyob rau hauv txoj hauj lwm qhib.
Gradual Closing: Close the high-voltage disconnector first, then the low-voltage disconnector, and finally the circuit breaker. Thaum lub sijhawm ua haujlwm, nruj me ntsis rau qhov "siab {{{{{}} voltage ua ntej, qis} voltage kawg" ib qho zuj zus. Kev Tswj Xyuas Kev Ua Haujlwm: Tom qab fais fab tau rov qab, saib cov hloov pauv lub suab ua haujlwm rau kev ruaj khov thiab tsis muaj kev sib txawv lossis cov ntxhiab tsw. Saib xyuas cov winding cua sov uas kub maub los kom ntseeg tau tias nws nyob hauv qhov ntsuas ntsuas (feem ntau tsis ntau tshaj 130 degree).
III. Lub zog ua haujlwm
Disconnecting lub load: Ua ntej disconnect qhov qis - voltage load hloov, ces qhov siab- voltage Circer.
Qhib cov txheej txheem: Qhib qhov qis - voltage disconnector disconnector thiab ces} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {
Kev rho tawm: Yog tias tus hloov pauv yog tawm ntawm kev pabcuam rau lub sijhawm ncua sijhawm, tso tawm lub siab {{voltage sab los tiv thaiv ib qho kev them nqi uas tsis muaj kev phom sij.
IV. Cov kev ceev faj
Yuav tsum muaj ib puag ncig: qhuav {- hom transformers yuav tsum tau muab tso rau hauv ib qho chaw pa roj dawb. Kev ua haujlwm ua haujlwm yuav tsum tsis pub tshaj 40 degree.
Kev tu neeg tsis tu ncua: Khij lub rwb thaiv tsev Rwb thaiv tsev tsis kam rau peb lub hlis twg thiab ntxuav lub tshav kub hmoov av tas li txhua xyoo.
Kev ua haujlwm tsis zoo: Yog tias muaj suab nrov tam sim no, lossis cov khoom siv tiv thaiv txawv txawv tshwm sim, tam sim ntawd disconawm hluav taws xob muab thiab daws teeb meem.
Kev ua haujlwm kom raug ntawm qhuav -}} hom transform yog tus yuam sij rau kev ua haujlwm ruaj khov ntawm lub zog. Cov neeg ua haujlwm yuav tsum ua raws txoj cai tswj hwm kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov khoom siv.
