01 General
1.1 Project Background
Qhov no 1000kVAvpi transformer uayog xa tawm mus rau South Africa thaum Lub Xya Hli, 2024. Pawg vector ntawm no transformer yog Dyn11. Dyn11 kev twb kev txuas txoj kev, high voltage zoo, nruab nrab taw tes tsis drift. Thawj qhov hluav taws xob yog 11 kV, qhov nruab nrab qhov hluav taws xob yog 0.55 kV, lub tshuab hloov pauv yog nruab nrog tsis muaj qhov hloov pauv hloov pauv, qhov tapping ntau yog ± 2 * 2.5% ntawm thawj sab, qhov txias yog ONAN / ONAF.
Covqhuav hom transformerNws muaj cov yam ntxwv ntawm cov nplaim hluav taws kub retardant qauv, tsis tshua muaj suab nrov, lub teeb yuag, me me hneev taw, poob qis, kev nyab xeeb, ruaj khov, siab kub tsis kam thiab muaj zog tshaj qhov muaj peev xwm. Nrog nws cov kev ua tau zoo heev tau txais tos los ntawm kev lag luam hauv tsev, cov khoom lag luam raug xa tawm mus rau European Union, North America, Middle East thiab lwm thaj chaw kev lag luam thoob ntiaj teb.

1.3 Cov duab kos
1000 kVA vpi transformer daim duab kos duab thiab loj.
02 Kev tsim khoom
2.1 Core
Cov tub ntxhais hlau txais kev pom zoo permeability magnetic grain orientation txias dov silicon steel ntawv (CRGO), tag nrho oblique tsis- qhov khi, ua -hauv rub phaj qauv, tsim cov duab kos duab, txiav txim siab cov yam ntxwv ntawm cov ntawv sib nqus siv thiab ntau cov ntsiab lus, suav nrog kev tswj kev vibration, qaij txoj hauj lwm thiab lwm yam kev xav tau thiab lwm yam kev hloov kho kom zoo nkauj, yog li kev hloov pauv tsis zoo, thiab lwm yam. tsis muaj-load tam sim no, me tsis muaj-load poob. Tsawg suab nrov.
2.2 Cua txias
Lub high voltage coil txais cov qauv nruam winding, coil tshav kub dissipation yog zoo, yog li ntawd lub overload muaj peev xwm ntawm lub transformer yog muaj zog, thiab lub siab surge voltage yog kev ntseeg siab. Qhov qis-voltage kauj yog ntawv ci, thiab qhov kub ntawm qhov sib faib hauv qhov cua yog qhov sib npaug, uas txhim kho qhov ruaj khov ntawm lub kauj thiab txhim kho qhov luv - Circuit Court tsis kam. Lub kauj siv lub tshuab nqus tsev siab impregnated H-chav hluav taws xob retardant xim, thiab kho tau ntawm qhov kub thiab txias, thiab qhov saum npoo tuaj yeem ua plua plav, noo noo- pov thawj thiab stain- pov thawj.
2.3 Lub Rooj Sib Tham Kawg
Winding qhov chaw: thawj winding thiab theem nrab winding yog ntsia rau ntawm cov tub ntxhais hlau raws li tus qauv tsim.
Winding kev twb kev txuas: Txuas lub winding davhlau ya nyob twg raws li cov hluav taws xob kos duab los xyuas kom meej qhov kev twb kev txuas yog ruaj khov.
Cov ntaub ntawv rwb thaiv tsev: Muab cov ntaub ntawv rwb thaiv tsev (xws li cov ntawv insulating thiab cov roj insulating) raws li cov qauv tsim kom ntseeg tau tias kev ruaj ntseg ntawm cov rwb thaiv tsev. Rwb thaiv tsev kuaj: ib qho kev ntsuas rwb thaiv tsev yog ua los xyuas kom meej tias cov rwb thaiv tsev ua tau raws li cov kev qhia tshwj xeeb.
Cov kiv cua lossis cov cua txias: Nruab lub tshuab hloov pauv cov kiv cua lossis cov cua txias kom ntseeg tau tias cov cua txias tuaj yeem ua kom cov cua sov tau zoo.
Plhaub fixation: Nruab lub plhaub los yog tus neeg saib xyuas ntawm lub transformer nyob rau hauv qhov chaw kom paub meej tias lub plhaub yog kaw nrog lub ntsiab lub cev ntawm lub transformer.
Cable kev twb kev txuas: Txuas lub siab thiab tsis tshua muaj voltage cables ntawm lub transformer kom paub meej tias cov hluav taws xob kev twb kev txuas yog muaj zog thiab ua tau raws li cov qauv kev ruaj ntseg.
Grounding: Ua kev kho av kom ntseeg tau tias cov av ntawm lub tshuab hloov pauv tau zoo.
