Cov khoom siv zoo li cas rau cov roj immersed transformers?

Roj immersed transformer tau tshaj rwb thaiv tsev cov ntaub ntawv:

Raws li koj cov lus nug yav dhau los txog GPO3, SMC, thiab epoxy, thov qhia lawv txhua lub sijhawm thiab yuav ncaj qha.

1, Lub sij hawm ntev immersion nyob rau hauv roj ✅ Pom zoo (Core Internal Cheebtsam)

Epoxy series (thawj xaiv rau roj transformation)

-Epoxy iav ntaub laminated board 3240/EPGC201/203
Resistant rau transformer roj, siab kub, thiab ruaj khov loj. Haum rau coil partitions, siab strips, txhuas rwb thaiv tsev, thiab clamp rwb thaiv tsev.
-Epoxy DMC/Oil resistant Epoxy SMC
Puab molded qhov chaw: rwb thaiv tsev txhawb nqa, davhlau ya nyob twg ncej, zoo li tus txhawb nqa, tuaj yeem ua rau tag nrho.
-Epoxy iav raj, epoxy pas nrig
Insulated pas nrig thiab lub tes tsho sab hauv kev txhawb nqa, ruaj khov hauv cov roj.

Traditional composite rwb thaiv tsev (tus qauv rau transformers)

-Lingge adhesive rwb thaiv tsev ntawv, corrugated ntawv, cable ntawv
-Laminated ntoo, hluav taws xob cardboard (siab phaj, cushion thaiv)
👉 Winding, interlayer, thiab kawg pads, paub tab roj transformer nrog ib puas xyoo ntawm kev paub.

2, Tsis tuaj yeem muab tso rau hauv cov roj rau lub sijhawm ntev ⚠️ Tsuas yog saum cov roj qib / sab nraud

GPO3 (UPGM203) polyester fiberglass board
Unsaturated polyester cov ntaub ntawv, ntev - immersion nyob rau hauv cov roj kub yuav ua rau o, delamination, thiab rwb thaiv tsev degradation
✅ Muaj: Roj tank sab nrauv phab ntsa, sab nraud cais, qhuav hloov
❌ Disabled: Sab hauv cov khoom hauv cov roj
Ordinary polyester SMC / qub DMC
Tsis yog epoxy matrix, tsis tshua muaj roj tsis zoo, txwv tsis pub siv rau hauv cov roj stains

3, Txwv tsis pub ❌ Corrosion / cracking hauv roj

-Plastics: PVC, ABS, PP
-Cov ntaub ntawv tsis zoo polyester zoo tib yam, zoo tib yam fiberglass reinforced yas
-Universal tsev kho kom zoo nkauj epoxy thiab inferior resin qhov chaw
- Roj hmab (cov roj hmab ib txwm nthuav dav thiab muaj hnub nyoog thaum raug roj)

4, Kev xaiv cov ntaub ntawv raug raws li qhov chaw siv (cov tswv yim version)

Lub sij hawm ntev hauv roj immersion
Qhov tseem ceeb: Epoxy laminated board, epoxy pas nrig / raj, roj resistant epoxy SMC / DMC, hluav taws xob ntawv
Sab saum toj ntawm lub tank roj tsis tuaj yeem tiv nrog cov roj
Muaj: GPO3, zoo tib yam fiberglass board, engineering plastics
Qhov kub thiab txias (105-120℃mus ntev)
Tsuas yog xaiv: F-qib / H- cov ntaub ntawv qib epoxy, hluav taws xob tshwj xeeb cardboard

5, Cov ntsiab lus ceev hauv ib kab lus

Tsuav nws yog immersed nyob rau hauv transformer roj → tsuas yog siv epoxy system + transformer tshwj xeeb cardboard
Tsis muaj roj, cov khoom siv sab nraud → tuaj yeem siv GPO3, cov khoom siv hluav taws xob zoo tib yam los txo cov nqi
Polyester (GPO3, zoo tib yam SMC)=internal killer ntawm roj hloov, tsis txhob siv nws indiscriminately
