OSM transformers yog kauj ruam-down transformers ntawm armored, pas nrig los yog toroidal hom, tsim los rau lub hwj chim teeb pom kev zoo, tswj thiab automation circuits. Lawv tau tsim los rau lub zog ntawm 0.063 txog 4 kVA. Nyob ntawm nws, transformers txawv qhov ntev, mounting txoj kev thiab tshwj xeeb impregnation nrog ya raws-resistant insulating kua roj vanish. Thawj winding yog tsim los ua haujlwm nyob rau hauv qhov hluav taws xob ntawm 220 mus rau 660 V. Qhov thib ob tuaj yeem ua haujlwm ntawm 12 txog 260 V. Nws tuaj yeem muaj ob peb lub voj voog thib ob rau qhov sib txawv voltages. Yog li, qhov Scope ntawm transformers yog dav heev.

OSMs yog dab tsi?

OSM transformers yog dab tsi tuaj yeem nkag siab los ntawm lub npe nws tus kheej. Hauv qhov no, O yog ib theem. C - txhais tau tias qhuav, tsis siv roj transformer. Qhov no yog vim tsis muaj zog thiab muaj txiaj ntsig zoo ntawm qhov hnyav thiab qhov loj me. Cov kua roj vanish tshwj xeeb yog siv los tiv thaiv kev ya raws thiab oxidation. M txhais tau hais tias nws muaj ntau yam.

Hom kev tiv thaiv hluav taws xob yog chav kawm I, thiab qib kev tiv thaiv yog IP00,Txawm li cas los xij, tus neeg siv khoom tuaj yeem ua tus hloov pauv nrog IP20 tiv thaiv kev tiv thaiv. Thov nco ntsoov tias transformers tsis yog tsim los rau kev teeb tsa hauv qhov chaw tawg.

Tiv thaiv kev vibration load nrog zaus ntawm 10 txog 60 Hertz. Qhov siab tshaj plaws acceleration nyob rau hauv cov ntaub ntawv no yuav tsum tsis txhob ntau tshaj 2g. Muaj peev xwm tiv taus qhov cuam tshuam txog li 8g acceleration.

Nco ntsoov tias ntxiv rau qhov tsim ntawm hom armored, kuj muaj OSM T transformers. Qhov no, T txhais tau tias nws yog hom toroidal. Roughly hais lus, nws muaj cov duab ntawm ib tug donut. Nrog tib lub zog, xws li transformers sib dua thiab me me.

Tsim

Transformer OCM 0.25, 1 lossis 4 kVA tuaj yeem ua armored, pas nrig lossis toroidal hom. Kev xaiv ntawm ib lossis lwm qhov kev xaiv nyob ntawm cov chaw tsim khoom, nws lub peev xwm thiab cov khoom siv. Hom siv tsis muaj qhov cuam tshuam loj rau kev ua haujlwm lossis kev ntseeg tau.

Cores rau txhua txoj kev xaiv yog ua los ntawm cov hlau hluav taws xob. Nyob rau hauv pas nrig thiab toroidal hom transformers, lub winding muaj ib tug core. Tab sis nyob rau hauv armor, ntawm qhov tsis tooj, cov tub ntxhais muaj ib tug winding.

Cov coils muaj cov ncej tsim. Cov khoom siv yog tooj liab. Cov hlau yog encased nyob rau hauv tshav kub-resistant rwb thaiv tsev.

Qhov pib ntawm theem nrab thiab thawj windings yog qhia nyob rau sab saum toj ntawm transformer. Thawj sib raug rau lub npe "O", thiab qhov thib ob - "U".

Txhim kho nta

Lub tshuab hloov pauv yog npaj rau kev teeb tsa hauv cov khoom siv uas txhua qhov kev tiv thaiv kev tiv thaiv: tiv thaiv hluav taws xob, dej ingress thiab overload - yog ua los ntawm cov khoom siv nws tus kheej. Cov windings yog impregnated nrog ya raws insulating kua roj vanish, nqa tawm nyob rau hauv ib lub tshuab nqus tsev chamber. Nws tsis pom zoo kom nruab transformers nyob rau hauv ib puag ncig uas muaj fumes uas muaj alkalis thiab acids uas yuav ua rau cov khoom puas los ntawm cov khoom ntawm cov cuab yeej tsim.

Txhua tus khau clamp yog tsim los txais tsis pub ntau tshaj ob txoj hlua txhuas lossis tooj liab. Lawv qhov siab tshaj plaws hla yuav tsum tsis pub tshaj 2.5 hli. Cov ntaub ntawv ntawm cov cuab yeej yuav tsum tau grounded. Cov zis ntawm qhov thib ob winding kuj yog grounded yog tias nws yog siv rau teeb pom kev zoo. Rau kev nyab xeeb kev ua haujlwm, cov rwb thaiv tsev tiv thaiv yuav tsum tsis pub tsawg dua 0.5 MΩ.

Transformers los ntawm 1.6 kVA yog tsim los rau kev teeb tsa ntawm kab rov tav nkaus xwb. Cov qauv nrog lub zog ntawm 1 kVA thiab hauv qab no tuaj yeem ntsia tau rau ob qho tib si kab rov tav thiab ntsug.

Hom kev nyab xeeb tsim

OSM transformers tuaj yeem ua hauv cov qauv hauv qab no:

  • U3 - thawj tsab ntawv nyob rau hauv cov ntaub ntawv no txhais tau hais tias ib tug temperate huab cua nyob rau hauv uas lub transformer muaj peev xwm ua hauj lwm. 3 yog cov pab pawg, uas yog sab hauv tsev nrog cov cua zoo.
  • T3 - tsim los ua haujlwm hauv huab cua sov, ob qho tib si nrog huab cua qhuav thiab nrog cov av noo siab. Pawg kev pab yog tib yam li hauv qhov kev xaiv dhau los.
  • UHL3 -sawv cev rau huab cua sov lossis txias.

Yog li, txhua txoj kev xaiv tsuas yog siv sab hauv tsev xwb. Tsis muaj kev ua haujlwm sab nraum zoov lossis hauv qab lub qhov rooj. Lawv txawv ntawm ib leeg xwb nyob rau hauv ib tug tiv thaiv txheej los ntawm sab nraud ib puag ncig, tab sis cov yam ntxwv ntawm OSM transformers thiab qhov ntev yog tib yam.

Deciphering indices

Koj tuaj yeem pom ntau qhov sib txawv rau OSM transformers: 0.4, U3, 380 thiab lwm yam. Cia peb txheeb xyuas kom meej ntxiv seb lawv txhais li cas, siv qhov piv txwv ntawm OCM1-0, 5-U3-380 / 5-36-220 / 12 TU:

  • Tus naj npawb 1 ntawm qhov pib qhia tias lub tshuab hloov pauv yog thawj tus qauv.
  • 0.5 - ntsuas lub zog. Thov nco ntsoov tias yog lub transformer yog peb-winding, lub hwj chim yuav raug qhia raws li tag nrho rau ob windings.
  • U3 yog qhov kev nyab xeeb ntawm kev ua haujlwm.
  • 380 rau rooj plaub no qhia qhov hluav taws xob ntawm qhov pib winding.
  • 5-36-220 yog qhov voltages ntawm cov ceg ntoo ntawm qhov thib ob winding. Hauv qhov no, muaj peb.
  • 12 - voltage ntawm peb winding.
  • TU stands for specifications.

Kev thauj mus los thiab khaws cia

Thaum lub sijhawm thauj mus los, nws yog qhov yuav tsum tau tshem tawm txhua qhov kev puas tsuaj rau cov tshuab hloov pauv. Cov thawv yuav tsum tau kho kom ruaj ntseg raws li cov khoom thauj khoom thauj. Nws tseem yog ib qho tseem ceeb rau kev khaws cia thiab kev thauj mus los kom tsis txhob muaj kev ya raws los yog dej lwg ntawm qhov chaw. Khaws ntawm qhov txheeb ze av tsis tshaj 80 feem pua. Ua tsis tauLub xub ntiag ntawm acidic lossis alkaline fumes uas tuaj yeem ua rau cov khoom siv uas lub tshuab hloov pauv tau ua, nws cov impregnation lossis rwb thaiv tsev, lossis ua rau cov tsos ntawm oxide.
