Cov tshuab ziab khaub ncaws qhuav tau dhau los ua - rau kev xaiv rau kev teeb tsa sab hauv tsev hnub no. Lawv muaj kev nyab xeeb, ncaj nraim rau nruab, thiab zoo nkauj txhim khu kev qha tag nrho. Hauv tsab xov xwm no, kuv yuav taug kev koj los ntawm qhov tseem ceeb qhuav hom transformer rau sab hauv tsev installation specifications - txhua yam los ntawm cov qauv thiab cov ntsiab lus rau kev siv tswv yim thiab kev coj ua zoo tshaj.
Dab tsi yog qhov Dry Type Transformer?
Yeej, lub tshuab ziab khaub ncaws qhuav txias thiab insulates nws tus kheej siv cua lossis cov khoom siv zoo li epoxy resin, tsis yog roj. Tsis muaj cov kua nplaum nplaum txhais tau tias muaj kev pheej hmoo hluav taws tsawg, uas ua rau lawv zoo meej rau cov chaw hauv tsev xws li chaw ua haujlwm, tsev kho mob, tsev kawm ntawv, cov chaw zov me nyuam, thiab cov chaw ua haujlwm. Koj tsis tas yuav txhawj xeeb txog cov roj xau los yog cov txheej txheem kaw tsis zoo.
Vim Li Cas Lawv Zoo Rau Kev Siv Sab Hauv Tsev
Nov yog vim li cas ntau tus neeg xaiv lawv:
Yuav luag tsis muaj feem muaj roj- cuam tshuam txog hluav taws lossis nchuav
Lawv xav tau kev saib xyuas me me heev
Ntau tus phooj ywg zoo rau ib puag ncig
Yooj yim kom tau txais kev pom zoo raws li cov cai hauv tsev

Enclosure thiab tsim cov ntsiab lus
Rau kev siv sab hauv tsev, feem ntau tuaj hauv cov hom no:
NEMA 1ventilated enclosures - tus qauv xaiv rau feem ntau cov hauj lwm sab hauv tsev
IP20 lossis IP23qib tiv thaiv
Lub cev muaj zog steel nrog zoo qhov cua qhib
Tag nrho cov versions nyob ze (TENV) yog tias thaj chaw muaj plua plav lossis av noo
Cam khwb cia resin los yog VPI windings rau ntxiv durability
Cov Tswv Yim Txhim Kho Sab Hauv Tsev thiab Clearances
Tau txais lub installation txoj cai yeej tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm. Nov yog yam koj yuav tsum nco ntsoov:
Txoj Cai Clearance (raws li NEC thiab cov tswv yim tsim khoom):
Yam tsawg kawg 12 ntiv tes (300 hli) los ntawm cov phab ntsa combustible rau cov chav me me (txog 112.5 kVA)
Cov transformers loj dua feem ntau xav tau qhov chaw ntxiv lossis hluav taws kub - cov phab ntsa ntsuas
Tawm 6-12 ntiv ib ncig ntawm ob sab rau airflow
Khaws 3-4 ko taw meej pem hauv ntej kom koj tuaj yeem ua haujlwm rau nws
Kev xav tau cua tshuab:Chav tsev yuav tsum muaj huab cua zoo txaus - kwv yees li 2.5 mus rau 3 cubic meters ib feeb rau txhua kW ntawm kev poob. Khaws thaj chaw huv si, qhuav, thiab tsis kub dhau (max 40℃ambient zoo tagnrho).
Mounting Basics:
Muab nws tso rau ntawm ib qho khoom, qib pob zeb hauv pem teb
Ntxiv vibration pads yog hais tias lub suab yog ib qho kev txhawj xeeb
Tsis txhob hnov qab kom tsim nyog grounding
Kev nyab xeeb thiab kev tiv thaiv nta
