250 KVA Pad Mount Peb -Phase Roj-Immersed Distribution Transformer

 

Ua rau lub nroog compact thiab lub teeb muaj kev lag luam, qhov no 250 kVA ncoo -mounted transformer siv siab - zoo tooj liab los yog txhuas windings thiab roj - raus siv. Nws peb -theem tsim ua kom ruaj khov hluav taws xob xa khoom, thiab cov txheej txheem tso cai ncaj qha rau kev tshuaj xyuas thiab tu.

 

 

 

 

ZBW series prefabricated lub thawv- hom substation (feem ntau hu ua American-style box-hom transformer) nta "khoom"- qauv qauv. Nws cov transformer thiab siab / qis- cov khoom siv hluav taws xob tau sib xyaw ua ke rau hauv ib chav tsev. Ntawm nws cov qauv tsim tshwj xeeb, peb sab ntawm lub tshuab hloov pauv tau raug huab cua- kom ntseeg tau tias muaj cua sov zoo heev- thiab lub tshuab hloov pauv tuaj yeem raug cais tawm ntawm cov ntaub ntawv ntawm qhov siab thiab qis - cov khoom siv hluav taws xob, ua kom yooj yim txij nkawm.

Lub 813 series roj -immersed transformer yog nruab nrog ib tug nti- hom roj tank, yuav tsum tsis muaj roj cushion, thiab txais yuav ib tug tag nrho cov tsim. Cheebtsam xws li siab-voltage thiab low-voltage bushings, kais changers, roj theem ntsuas, siab nyem li qub, thiab roj ntws li qub yog tag nrho ntsia rau ntawm lub phaj kawg ntawm lub siab - siab chamber. Qhov kev teeb tsa no ua kom muaj qhov tsim nyog ntawm qhov chaw, ua kom yooj yim rau kev soj ntsuam thiab kev ua haujlwm.

Lub siab-siab chamber thiab qis-siab chamber yog sib cais los ntawm steel phaj. Thaum lub siab -siab chamber, qis- lub siab chamber, thiab transformer kuj muaj kev ywj pheej, lawv sib sau ua ib lub thawv ua tiav. Qhov kev tsim no ua rau cov qauv compact, ntim me me, thiab lub teeb yuag. Tsis tas li ntawd, lub tshuab hluav taws xob faib hluav taws xob tau teeb tsa ntawm ob lub siab -voltage thiab qis-voltage sab ntawm substation.

 

 

 

 

Lub ncoo-mounted transformer yuav tsum ua haujlwm nyob rau hauv ib puag ncig ib puag ncig kom ntseeg tau tias kev ua haujlwm ruaj khov thiab kev ua haujlwm nyab xeeb, nrog rau cov kev xav tau sib xyaw los ntawm ob qho tib si cov ntaub ntawv hauv qab no:

1. Qhov txias txias
Txais cua tus kheej- hom cua txias, tso siab rau cov huab cua hauv huab cua kom dissipate cua sov tsim thaum lub sijhawm ua haujlwm transformer, uas yog tsim rau nws cov qauv tsim thiab kev siv ntau yam scenarios.

 

2. Cua ceev:
Sib npaug rau 34m / s (tsis ntau tshaj 700 Pa);

 

3. Kev ntsuas kub

Qhov kub nruab nrab txhua hli yuav tsum tsis pub tshaj 30 degree, thiab qhov nruab nrab txhua xyoo yuav tsum tsis pub tshaj 20 degree. Qhov no txwv qhov ntev -lub sij hawm kub load ntawm lub transformer kom tsis txhob muaj kev degradation tshwm sim los ntawm huab cua tsub zuj zuj.

 

4. Qhov siab xav tau
Lub installation qhov siab yuav tsum tsis pub tshaj 1000m.

 

5. Yuav tsum muaj av noo
Ntawm qhov kub ntawm 25 degree, qhov siab tshaj plaws ntawm cov av noo ntawm huab cua yuav tsum tsis pub tshaj 95%, thiab qhov nruab nrab cov av noo txhua hnub yuav tsum tsis pub tshaj 90%.

 

6. Kev vibration thiab acceleration yuav tsum tau
Kab rov tav acceleration ntawm qhov chaw installation yuav tsum tsis txhob ntau tshaj 0.3g, thiab ntsug acceleration yuav tsum tsis txhob ntau tshaj 0.15g).

 

7. Kev Txhim Kho Platform Yuav Tsum Tau
Lub chaw teeb tsa yuav tsum huv si, tsis muaj cov pa tawg los yog corrosive, cov plua plav conductive, muaj zog vibration, thiab cuam tshuam. Txoj kev nqes hav yuav tsum tsis pub tshaj 3 degree, thiab lub transformer yuav tsum tau muab tso rau ntawm ib tug ca, cov cement platform kom ruaj khov.

 

8. Rau cov khoom xaj tshaj li cov xwm txheej tau teev tseg saum toj no, thov tham nrog peb lub tuam txhab.

 

 

 

 

• Me me, compact qauv, thiab yooj yim installation: Nws yuav siv tau rau ob lub nplhaib network thiab davhlau ya nyob twg daim ntawv thov, nrog txhim khu kev qha tus kheej kev ruaj ntseg tiv thaiv.
