Yuav Ua Li Cas Nres 1600kVA Transformer Overheating Hauv 50℃Suab puam Ambient Kub

Tom ntej: 1600kVA transformer overheating nyob rau hauv 50℃suab puam ambient kub yog ib qho ntawm feem ntau thiab kev puas tsuaj rau cov suab puam photovoltaic fais fab chaw nres tsheb, qhib- qhov mines thiab tej thaj chaw deb muaj hwj chim faib tshuab, qhov twg 1600kVA tis transformer ua hauj lwm raws li lub hauv paus tseem ceeb zog hloov dua siab tshiab thiab kis tau tus mob khoom.

Tus qauv fais fab transformers feem ntau yog tsim los rau qhov siab tshaj plaws ambient kub ntawm 40 degree. Txawm li cas los xij, feem ntau thaj chaw suab puam ntsib qhov kub ntxhov siab mus txog rau50 degree, ua ke nrog lub hnub ci hluav taws xob hnyav, huab cua qhuav thiab cua- tshuab xuab zeb. Xws li ib puag ncig hnyav yooj yim ua rau qhov kub thiab txias tsis zoo, thermal overload tripping, rwb thaiv tsev laus thiab txawm tias ntxov ntxov ntawm 1600kVA transformers.

 

Raws li Arrhenius thermal aging txoj cai, txhua txhua 10℃nce nyob rau hauv kev khiav hauj lwm kub yuav muab ob npaug rau cov laus tus nqi ntawm transformer cellulose rwb thaiv tsev, ncaj qha txiav cov cuab yeej siv lub neej los ntawm ib nrab.

 

Kab lus no tau txheeb xyuas cov txheej txheem thermal, cov hauv paus hauv paus, kev kuaj mob hauv cheeb tsam thiab cov phiaj xwm kev tiv thaiv kev daws teeb meem rau 1600kVA transformer overheating nyob rau hauv 50℃suab puam tej yam kev mob, muab cov txheej txheem kev ua tau zoo rau kev lag luam txawv teb chaws thiab kev ua haujlwm txhua hnub thiab kev saib xyuas.

 

Transformer overheating yog qhov tseem ceeb ntawm kev sib sau ntawm irreversible zog poob. Txhua lub tshuab hluav taws xob tsim hluav taws xob tsim hluav taws xob los ntawm ob lub cev tsis zoo, thiab 1600kVA nruab nrab- qauv muaj peev xwm ntau dua rau qhov siab tshaj - qhov kub thiab txias ib puag ncig vim nws lub peev xwm loj thiab lub zog ua haujlwm siab.

 

Ua ke nrog cov suab puam kub, xuab zeb plua plav thiab muaj zog hluav taws xob cov yam ntxwv, lub overheating ntawm 1600kVA transformers tsis yog tshwm sim los ntawm ib qho tseem ceeb tab sis lub superposition ntawm ib puag ncig, khoom siv thiab tib neeg yam. Rau qhov laj thawj tseem ceeb tau sau tseg raws li hauv qab no:

 

Kub Ambient Kub thiab Solar Radiant Kub Derating

Standard 1600kVA transformers yog tsim rau 40℃ambient kub. Thaum cov suab puam ambient kub mus txog 50℃thiab qhov kub thiab txias ntawm cov cuab yeej raug tshav ntuj ncaj qha tshaj 70 degree, transformer yuav tsum derated los ntawm 10%. Ntev-lub sij hawm dhau- qhov kub thiab txias ua haujlwm txo cov cua kub dissipation margin thiab ua rau cov cua sov tsis tu ncua.

 

 

Harmonic Distortion thiab daim tawv nqaij nyhuv cua sov

Suab puam photovoltaic cov cuab yeej tsim hluav taws xob, VFDs thiab cov khoom siv hluav taws xob tsim hluav taws xob tsim muaj ntau qhov siab - zaus harmonics. Cov nyhuv ntawm daim tawv nqaij ua rau tam sim no tsuas yog ncig ntawm qhov chaw ntawm cov hlau tooj liab, txo qhov zoo ntawm cov khoom siv hluav taws xob thiab ua kom muaj zog winding. Txawm hais tias 1600kVA transformer khiav ntawm 80% rated load, nws yuav tsim kom muaj cua sov sib npaug rau 120% overload.

 

Xuab zeb plua plav thaiv cov cua sov Dissipation Channel

Cua suab puam- tshuab xuab zeb thiab hmoov av zoo ua raws li lub tshuab hluav taws xob hloov hluav taws xob thiab lub qhov cua rau lub sijhawm ntev. Lub 2 hli tuab plua plav txheej yuav txo qhov ua kom txias ntawm 25%. Thaiv cov cua sov dissipation fins ua rau cov cua sov sab hauv tsis tuaj yeem tawm mus rau sab nraud, tsim cov txheej txheem thermal rwb thaiv tsev thiab ua rau cov roj kub siab ceev ceev.

 

 

Oil Aging thiab Sludge Accumulation

Ntev -lub sij hawm 50℃siab kub ceev cov oxidation cov tshuaj tiv thaiv ntawm transformer insulating roj, ua acidic tshuaj thiab viscous sludge. Cov sludge adheres rau windings thiab thaiv cov roj ducts sab hauv, rhuav tshem lub ntuj ncig ntawm cov roj insulating thiab tsim lub voj voog vicious ntawm "siab dua kub - ntau dua sludge - kub dissipation".

 

Loose Connection thiab Local High -Resistance Hotspots

Suab puam loj kub sib txawv nruab hnub thiab hmo ntuj ua rau nquag thermal expansion thiab contraction ntawm lub davhlau ya nyob twg pob qij txha thiab kais changers. Lub sijhawm ua haujlwm ntev - ua rau muaj kev sib txuas tsis sib xws, ua rau siab - cov ntsiab lus tsis kam. Concentrated tam sim no cua sov ua rau cov chaw kub hauv zos, uas yog ib qho yooj yim los ua ib feem ntawm qhov paug tawm thiab arcing faults.

 

Kev teeb tsa tsis tsim nyog thiab tsis txaus qhov chaw cua

Ntau cov suab puam ib ntus substations txais kev teeb tsa compact. Lub 1600kVA transformer tsis muaj cov txheej txheem cua sov dissipation clearance, thiab cov cuab yeej kaw hauv chav ua cov cua kub rov qab. Cov cua kub uas tsis tuaj yeem tso tawm, ua rau cov khoom siv thermal khiav tawm.

 

Rau qhov ua rau saum toj no tsis tshua muaj tshwm sim hauv kev sib cais. Yog tias koj pom tias cov roj saum toj kawg nkaus ntawm koj lub tshuab hloov pauv tau nce siab dua 5℃piv rau tib lub sijhawm ntawm lub hli dhau los, lossis yog tias pom cov xuab zeb / plua plav pov tseg nyob rau ntawm lub tshuab hluav taws xob fins, nws qhia tau tias tsawg kawg 2-3 qhov kev ua txhaum loj tuaj yeem tshwm sim sab hauv. Tsis yog qhov muag tsis pom kev teem caij rau kev saib xyuas, siv peb daim ntawv teev tshuaj ntsuam xyuas sai sai raws li kev cai-tsim rau cov kws ua haujlwm hauv teb chaws suab puam tej yaam num- txhawm rau txheeb xyuas thaj chaw muaj kev ntseeg siab.

Siv 2-feeb kev kuaj xyuas tus kheej

 

 

Txhawm rau txheeb xyuas qhov ua rau muaj cua sov ua kom raug, cov neeg ua haujlwm tu vaj tse yuav tsum ua raws cov txheej txheem txheej txheem -los ntawm - kev kuaj xyuas cov kauj ruam kom tsis txhob saib xyuas qhov muag tsis pom:

 

Kauj Ruam 1: Sau cov ntsiab lus tseem ceeb, suav nrog lub npe hloov pauv qhov ntsuas kub nce siab, tiag - lub sijhawm suab puam ambient kub, peb - theem load tam sim no thiab kev khiav hauj lwm voltage.

 

Kauj ruam 2: Ua tag nrho - taw tes infrared thermal imaging nrhiav kom pom qhov kub ntawm qhov sib txawv ntawm lub tshuab hluav taws xob fins, lub thawv lub cev, bushing terminals thiab kais hloov pauv; qhov sib txawv ntawm qhov kub siab tshaj 10℃ntawm cov theem qhia tau hais tias qhov txawv txav.

 

Kauj ruam 3: Xam qhov tseeb load npaum li cas thiab peb -theem voltage imbalance; qhov voltage tsis sib npaug tshaj 2% yuav ua rau asymmetric cua sov ntawm windings.

 

Kauj Ruam 4: Tshawb xyuas qhov ua kom txias kom pom, xyuas cov roj theem ntawm cov roj- raus transformers, kiv cua ua haujlwm raws li txoj cai thiab plua plav thiab xuab zeb thaiv ntawm cov cua kub cua.

 

Kauj Ruam 5: Ua qhov kev ntsuam xyuas lub zog zoo los kuaj tag nrho cov kev sib haum xeeb sib txawv (THD); THD tam sim no tshaj 15% yuav ua rau muaj kev sib haum xeeb hnyav.

 

Kauj Ruam 6: Kev tshawb pom tob tob, suav nrog DGA yaj tshuaj ntsuam xyuas (kev txiav txim siab sab hauv thermal faults) thiab DP polymerization℃kev xeem (kuaj ntsuas kev tiv thaiv kev laus).

 

 

Lub hom phiaj ntawm 50℃suab puam huab cua ua haujlwm, peb muab cov kev daws teeb meem zoo suav nrog kev tsim kho lub Hoobkas, kev teeb tsa tus qauv, ntawm - hloov chaw thiab kev saib xyuas txhua hnub kom daws tau cov teeb meem overheating.
