2500 KVA Loop Feed Transformer-12.47*24.94/0.6 KV|Canada 2025

01 General

1.1 Project Description

Peb tus khub Canadian, nrog ntau dua 30 xyoo ntawm kev paub hauv kev lag luam fais fab, tau tso siab rau Scotech. Thaum lub Cuaj Hlis 2025, tau xaj tag nrho 66 lub ncoo-mounted thiab ncej-mounted transformers los ntawm peb.

Scotech ua cov kev daws teeb meem rau txhua qhov project. Lawv qhov kev txiav txim zaum kawg yog rau ob lub voj voog 2500 kVA - pub peb -theem ncoo- mounted transformers. Lawv raug tsim los rau CSA C227.4:21 tus qauv. Cov kev hloov pauv no tuaj yeem siv tau rau ntau qhov haujlwm, suav nrog cov chaw khaws ntaub ntawv, crypto txiaj mining, kev siv hluav taws xob, hluav taws xob tauj dua tshiab, kev lag luam, thiab kev tsim kho.

Qhov no transformer ua haujlwm nrog input voltages ntawm 12.47 kV thiab 24.94 kV. Nws muab 0.6 kV rau sab thib ob thiab muaj peev xwm siab tshaj plaws ntawm 2500 kVA. Lub dual thawj voltage cia nws txuas mus rau cov kab sib txawv. Nws yog qhov zoo rau cov khoom siv hluav taws xob, cov tsev lag luam, thiab cov chaw lag luam. Lub transformer muaj ONAN txias system. Nws siv siab - roj ntxhia zoo thiab tsis muaj PCBs. Qhov no ua rau nws muaj kev nyab xeeb, txhim khu kev qha, thiab ib puag ncig tus phooj ywg.

Lub transformer muaj Dyn1 vector pawg. Nws muaj NLTC kais hloov pauv nrog tapping ntau ntawm ± 2 × 2.5%. Lub transformer ua raws li CSA C802.1-13 efficiency standard. Nws tag nrho efficiency yog 99.37%, uas yog siab tshaj li feem ntau transformers ntawm no loj. Nws tsis muaj-load poob ntawm 2.5 kW thiab ntawm -load poob ntawm 24 kW yog ob qho tib si qis, cuam tshuam cov qauv tsim qauv zoo thiab cov khoom siv winding zoo. Lub transformer siv tsawg zog, nqi tsawg dua khiav, thiab ua haujlwm zoo rau lub sijhawm ntev.

02 Kev tsim khoom

2.1 Core

Lub eclectic transformer core yog ib qho tseem ceeb nyob rau hauv lub hwj chim transformers, ua hauj lwm raws li ib tug sib nqus Circuit Court thiab yooj yim hloov lub zog ntawm cov thawj thiab thib ob windings. Peb cov cores yog tsim los ntawm siab - zoo silicon steel laminations, tsim los txo lub zog poob thaum ua kom muaj qhov sib nqus flux ceev. High- zoo transformer cores txo lub zog poob raws li cua sov.

 

2.2 Cua txias

Nrog rau kev tsom mus rau kev ua tau zoo thiab qhov chaw optimization, lub tsev siv ob qho tib si aluminium winding thiab tooj liab busbar txuas. Feem ntau ntawm peb peb -theem ncoo- mounted transformers txais ib qho kev ua kom zoo coil qauv ntawm cov ntawv ci winding rau qis-voltage coils thiab xaim winding rau siab -voltage coils, thiab chav tsev no ua raws li tus qauv tsim. Qhov kev tsim no ua kom muaj kev ntseeg siab, kev ua haujlwm ruaj khov, thiab kev ua haujlwm zoo dua thermal.

 

2.3 Tank

Tag nrho cov enclosures yog tsim los ntawm hnyav - ntsuas me me hlau thiab hmoov coated tag kom muab ib tug ruaj, tamper- resistant nto. Scotech ncoo-mounted transformers tiv taus ob qho tib si tampering thiab hnyav huab cua, ua rau lawv muaj kev nyab xeeb rau kev teeb tsa hauv thaj chaw pej xeem. Lub tank sab nrauv yog pleev xim rau Seafoam Green, muab lub ntsej muag huv, kev tshaj lij.

 

2.4 Lub Rooj Sib Tham Kawg

1. Core los ua ke: Cov tub ntxhais sib dhos ntawm kem transformer yog sib sau ua ke ntawm lub hauv paus transformer lossis thav duab ruaj khov raws li cov qauv tsim.

2. Winding los ua ke: Winding hlau ntawm ib qho kev qhia tshwj xeeb yog qhov txhab ntawm cov tub ntxhais hlau ntawm lub tshuab hluav taws xob raws li kev tsim qauv, suav nrog thawj winding thiab theem nrab winding. Siv rwb thaiv tsev los cais cov winding coils.

3. Rwb thaiv tsev kho mob: lub winding yog insulated, nrog rau insulating xim kev kho mob thiab ci, kom ntseeg tau zoo rwb thaiv tsev kev ua tau zoo.

4. Txhim kho lwm yam khoom: peb resin - nrum LV bushings (spade- hom, 8 qhov), peb HV bushings (separable insulated connectors, 200 A), rau bayonet fuses, rau ELSP fuses, ib tug 2- txoj hauj lwm load break switch, ib de{{9} ± 2% energized dual-voltage selector hloov thiab lwm yam.

5. Rwb thaiv tsev roj txhaj tshuaj: Cov roj rwb thaiv tsev yog txhaj rau hauv lub tank transformer roj los sau cov transformer sab hauv qhov chaw thiab xyuas kom meej tias cov roj qib siab raws li qhov yuav tsum tau ua.
