1. Lub hom phiaj thiab cov ntaub ntawv ntawmtransformerkev saib xyuas
ib.Lub hom phiaj ntawm kev tu transformer
Lub hom phiaj tseem ceeb ntawm kev tu transformer yog los xyuas kom meej tias lub transformer thiab accessories 'internal thiab sab nraud cov khoomtau khaws cia rau hauv qhov zoo, "tsim rau lub hom phiaj" thiab tuaj yeem ua haujlwm nyab xeeb txhua lub sijhawm.Qhov tseem ceeb sib npaug yog khaws cov ntaub ntawv keeb kwm ntawm lub tshuab hloov pauv.
b.Cov ntaub ntawv tu transformer
Fais fab transformers xav tau ntau yam kev tu vaj tse niaj hnub, nrog rau kev ntsuas thiab ntsuas qhov sib txawv ntawm cov transformer.Muaj ob hom kev hloov pauv hloov pauv tseem ceeb.Peb ua ib pab pawg ib ntus (hu ua kev saib xyuas kev tiv thaiv) thiab thib ob ntawm qhov tshwj xeeb (piv txwv li, ntawm qhov xav tau).
2. Lub Hlis Lub Sij Hawm Hloov Hloov Kho Kev Kho Mob
- Cov roj qib hauv lub hau roj yuav tsum tau kuaj xyuas txhua hli kom tsis txhob poob qis dua qhov txwv, thiab yog li kev puas tsuaj los ntawm nws raug zam.
- Khaws cov qhov ua pa hauv lub silica gel ua pa lub raj kom huv si kom paub meej tias kev ua pa kom zoo.
-Yog kojfais fab mov transformermuaj roj puv bushes, xyuas kom meej tias cov roj puv kom raug.
Yog tias tsim nyog, cov roj yuav muab ntim rau hauv lub bushing mus rau theem kom raug.Roj filling yog ua nyob rau hauv lub kaw lus kaw.
3. Kev tu thiab xyuas txhua hnub
- Nyeem MOG (Magnetic Oil Meter) ntawm lub tank loj thiab lub tank cia.
- Cov xim ntawm silica gel nyob rau hauv ua pa.
- Roj los ntawm txhua qhov chaw ntawm lub transformer.
Nyob rau hauv cov kev tshwm sim ntawm ib tug tsis txaus siab roj theem nyob rau hauv lub MOG, cov roj yuav tsum tau muab sau rau hauv lub transformer, thiab tag nrho cov transformer tank yuav tsum tau kuaj xyuas cov roj to.Yog tias pom cov roj xau, ua qhov tsim nyog los kaw qhov xau.Yog tias cov silica gel dhau los ua xim liab me ntsis, nws yuav tsum tau hloov.
4. Lub sijhawm ua haujlwm txhua xyoo transformer txij nkawm
- Lub tshuab tsis siv neeg, chaw taws teeb, thiab phau ntawv ua haujlwm ntawm lub tshuab ua kom txias txhais tau hais tias cov roj twj tso kua mis, cua kiv cua, thiab lwm yam khoom siv koom nrog lub tshuab hluav taws xob cua txias thiab tswj Circuit Court.Lawv yuav raug tshuaj xyuas hauv ib xyoos.Nyob rau hauv cov ntaub ntawv ntawm malfunction, soj ntsuam cov tswj Circuit Court thiab lub cev mob ntawm lub twj tso kua mis thiab kiv cua.

5. Transformer txij nkawm ntawm ib nrab xyoo
Koj lub hwj chim transformer yuav tsum tau sim txhua rau lub hlis rau IFT, DDA, flash point, sludge cov ntsiab lus, acidity, dej ntsiab lus, dielectric zog, thiab transformer roj kuj.
6. Kev tu ntawmTam sim no Transformer
Tam sim no transformers yog ib qho tseem ceeb ntawm txhua yam khoom siv nruab rau hauv qhov chaw nres tsheb fais fab los tiv thaiv thiab ntsuas hluav taws xob.
Lub zog rwb thaiv tsev ntawm lub CT yuav tsum tau kuaj xyuas txhua xyoo.Nyob rau hauv tus txheej txheem ntawm kev ntsuas rwb thaiv tsev, nws yuav tsum nco ntsoov tias muaj ob theem rwb thaiv tsev nyob rau hauv tam sim no transformers.Qhov rwb thaiv tsev ntawm thawj CT yog qhov siab, vim nws yuav tsum tiv taus qhov system voltage.Tab sis theem nrab CT's muaj qhov tsis tshua muaj rwb thaiv tsev feem ntau ntawm 1.1 kV.Yog li ntawd, thawj mus rau theem nrab thiab thawj lub ntiaj teb ntawm tam sim no transformers yog ntsuas nyob rau hauv 2.5 los yog 5 kV meggers.Tab sis qhov no high voltage megger tsis tuaj yeem siv rau kev ntsuas theem nrab vim tias qib rwb thaiv tsev kuj qis los ntawm tus qauv tsim kev lag luam pom.Yog li ntawd, cov rwb thaiv tsev thib ob yog ntsuas hauv 500 V megger.Yog li, thawj lub davhlau ya nyob twg rau lub ntiaj teb, thawj lub davhlau ya nyob twg mus rau qhov ntsuas thib ob, thiab lub davhlau ya nyob twg rau cov tub ntxhais tiv thaiv thib ob yog ntsuas hauv 2.5 lossis 5 kV meggers.
Thermo vision scanning ntawm thawj terminals thiab sab saum toj dome ntawm CT nyob yuav tsum tau ua tsawg kawg ib zaug hauv ib xyoos.Qhov kev tshuaj ntsuam no tuaj yeem ua tiav nrog kev pab los ntawm Infrared Thermal Surveillance Camera.
Txhua qhov kev sib txuas CT thib ob hauv CT lub thawv thib ob thiab CT junction lub thawv yuav tsum tau kuaj xyuas, ntxuav, thiab nruj txhua xyoo kom ntseeg tau tias qhov qis tshaj qhov ua tau CT theem nrab kev tiv thaiv.Tsis tas li ntawd, xyuas kom meej tias CT junction box raug ntxuav kom raug.
Cov khoom ntawm MBT Transformer
7. Kev tu txhua xyoo ntawmvoltage transformers los yog capacitor voltage transformers
Lub npog plooj (porcelain) yuav tsum tau ntxuav nrog paj rwb khaub ncaws.
Lub txim hluav taws xob sib dhos yuav raug kuaj xyuas txhua xyoo.Tshem tawm qhov txav ntawm qhov sib txawv ntawm qhov sib txawv thaum sib sau ua ke, ntxuav lub braes electrode nrog cov ntawv xuab zeb, thiab kho nws rov qab rau hauv qhov chaw.
High-frequency grounding point yuav tsum tau kuaj pom txhua xyoo yog tias qhov teeb meem tsis siv rau PLCC.
Thermal vision cameras yog siv los xyuas tej qhov chaw kub hauv lub capacitor stacks los xyuas kom meej cov kev kho kom zoo.
Terminal kev sib txuas PT hlws ris lub thawv muaj cov kev sib txuas hauv av kuaj kom nruj ib xyoos ib zaug.Tsis tas li ntawd, PT junction box yuav tsum tau muab ntxuav kom zoo ib xyoos ib zaug.
Qhov xwm txheej ntawm tag nrho cov pob qij txha gasket yuav tsum tau kuaj pom thiab hloov yog tias pom cov ntsaws ruaj ruaj puas lawm.
