Tso lus
Lub 200 kVA hnub ci photovoltaic qis- poob transformer yog peb -theem, roj- immersed tis transformer tsim los rau photovoltaic fais fab nroj tsuag thiab faib tiam systems. Tsab ntawv xov xwm no tsom mus rau S13-M hom, ib chav kaw tag nrho nrog tsis yog- kev tswj qhov hluav taws xob uas ua ke nrog cov tsis muaj kev poob qis nrog kev ua haujlwm sab nraum zoov, thiab piav qhia txog nws cov ntaub ntawv kev lag luam, qib rwb thaiv tsev, thiab cov ntawv thov raug.
S13-M 200 kVA Transformer yog dab tsi?
S13-M series yog peb-theem, cov roj ntim puv nkaus-immersed tis transformer. Hauv kev tsim qauv, S qhia txog peb theem -theem transformer, 13 hais txog qhov poob qis, uas yog qis dua li ntawm S11 units, thiab M txhais tau hais tias lub tank tau kaw tag nrho kom cov roj insulating tsis tiv nrog huab cua. Lub transformer yog tsim nrog hwm silicon steel laminations thiab oxygen-dawb tooj liab windings kom ua tiav qhov poob qis, tsis muaj suab nrov, thiab kev ua haujlwm siab nyob rau hauv lub hnub ci kev ua haujlwm tsis tu ncua.
Photovoltaic arrays tsim hluav taws xob thaum nruab hnub nrig thiab lawv cov zis hloov pauv nrog irradiance, yog li lub tshuab hloov pauv yuav tsum tau ua haujlwm ib ntus tsis tu ncua nrog qis tsis muaj -load poob. Qhov qis tsis muaj -load poob ntawm S13-M tsim ncaj qha txo cov zog siv thaum hmo ntuj thiab thaum lub sijhawm huab cua, uas txhim kho lub zog tag nrho ntawm cov nroj tsuag.

Yog vim li cas qis -Poob Transformers Suit Solar Plants
Tsawg tsis muaj-load poob yuav txo tau lub zog noj thaum hmo ntuj thiab nyob rau hauv qis- lub sij hawm irradiance.
Kev ua haujlwm ruaj khov nyob rau hauv qhov hloov pauv cov zis tawm los ntawm photovoltaic arrays.
Roj-immersed, tag nrho kaw kev tsim kho yog tsim rau sab nraum zoov installation nyob rau hauv hnub ci teb.
Sealed tank tsim minimizes txij nkawm thiab tiv thaiv kom tsis txhob ya raws.
Cov roj ntxhia lossis eco- cov kua dej ester zoo tuaj yeem xaiv tau raws li qhov chaw yuav tsum tau ua.
