01 General

1.1 Project Description

750 kVA uapeb theem ncoo mounted transformertau xa mus rau Tebchaws Meskas hauv xyoo 2025. Lub zog ntsuas ntawm ansi transformer yog 750 kVA nrog KNAN txias. Qhov siab voltage yog 12.47D kV nrog ± 2 * 2.5% tapping ntau (NLTC), qhov tsawg voltage yog 0.48Y / 0.277 kV, lawv tsim ib tugpawg vectorntawm Dyn1.

Qhov no 750kVA ncoo-mounted transformer nta ib lub voj-feed configuration rau txhim khu kev pab cuam txuas ntxiv nyob rau hauv underground tis network. Nws tau ntim nrog FR3 natural ester kua, muab hluav taws kub tsis kam thiab biodegradability. Tsim kom tau raws liDOE cov qauv kev siv hluav taws xob, transformer xyuas kom tsis tshua muaj kev poob thiab txhim khu kev qha ua haujlwm. Qhov ntsuas kub nce siab yog teem rau ntawm 65℃rau roj thiab winding (nruab nrab), thiab 80℃rau kub-spot. Lub kaw lus tau ua tiav nrog cov hmoov txheej hauv cov xim dawb (RAL 9003), muab kev tiv thaiv corrosion rau sab nraum zoov pad- daim ntawv thov.

02 Kev tsim khoom

2.1 Core: Ua haujlwm siab, poob qis, ruaj khov Foundation

Cov tub ntxhais yog ua los ntawm high-permeability, qis- poob premium txias-rolled grain-oriented silicon steel. Cov kauj ruam -lap joint thiab tag nrho mitered core qauv zoo txo ​​tsis muaj-load poob thiab tsis muaj-load tam sim no. Lub hauv paus yog annealed kom tshem tawm cov kev ntxhov siab sab hauv, ua kom ntev - lub sij hawm sib nqus ruaj khov. Qhov saum npoo yog coated nrog ib tug tshwj xeeb insulating kua roj vanish rau xeb thiab corrosion tiv thaiv, muab ib tug txhim khu kev qha lub hauv paus rau lub transformer lub lag luam ruaj khov.

 

2.2 Windings: Aluminium Conductor Design, Economical thiab Practice

Cov windings siv high- zoo aluminium conductors, nrog inter-tig rwb thaiv tsev ua los ntawm high- cov ntaub ntawv kub. Qhov qis-voltage windings siv cov ntawv ci-winding qauv los txhim kho luv luv-circuit tiv taus; lub siab-voltage windings siv ib txheej-mob los yog sectional-winding qauv los txhim kho xob laim impulse withstand peev xwm. Cov khoom nta aDyn1 kev sib txuaskom ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem rau theem hloov thiab nruab nrab hauv av. Lub compact qauv ua tau raws li qhov yuav tsum tau siv rau hauv cov qauv ib puag ncig.

 

2.3 Tank: Kev tsim kho me me, Customizable tsos

Lub tank ansi transformer yog tsim los ntawm siab - zoo me me steel, muab cov qauv zoo thiab ruaj khov. Qhov saum npoo yog kho nrog cov hmoov electrostatic txau, muaj nyob rau hauv cov xim xim dawb (RAL 9003), muab lub ntsej muag huv si, niaj hnub zoo sib xws nrog ib puag ncig ib puag ncig. Lub kaw lus muaj kev tiv thaiv txhim khu kev qha thiab tsim nyog rau kev teeb tsa sab nraum zoov.

 

 

03 Daim Ntawv Thov: Dav Adaptability rau ntau yam xwm txheej

No series ntawm ncoo-mounted transformers yog tsim tshwj xeeb rau sab nraum zoov, hauv av- theem installation thiab yog dav siv nyob rau hauv:

• Cov zej zog nyob thiab cov chaw lag luam
• Muaj chaw ua si, factories, thiab mining chaw
• Nroog toj roob hauv pes thiab municipal engineering tej yaam num
• Cov chaw txhawb zog tshiab (xws li photovoltaic thiab lub zog cia cov haujlwm)

Nws cov qauv kev cog lus, kev tsim kev tiv thaiv tag nrho, thiab muaj peev xwm sib xyaw nrog ib puag ncig ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hluav taws xob hauv nroog.

 

 

04 ua raws

4.1 Parameter Matching: Precisely Aligned kom tau raws li qhov yuav tsum tau muaj

Cov khoom yog nruj me ntsis tsim raws li tus neeg siv khoom qhov system tsis ua kom ntseeg tau tias:
