01 General

1.1 Project Description

Cov100 kVA lub teeb ncej transformeryog npaj rau 13.8 kV peb -theem nyiaj siv ua haujlwm faib tshuab los muab siab dua- muaj peev xwm thauj khoom, xws li cov chaw nyob ruaj khov lossis cov chaw lag luam me. Nws kuj ua raws li IEEE C57.12.20, nta ONAN txias nrog cov ntxhia roj rwb thaiv tsev, thiab siab -voltage tooj liab thiab qis-voltage aluminium windings. Qhov nruab nrab cov zis yog 120/240 V. Tsis yog-load poob yog kwv yees li 0.25 kW, load poob 0.897 kW, ua rau tag nrho poob ntawm 1.147 kW, thaum efficiency tseem siab tshaj 98%.

Impedance yog 2.86%, raws li tus qauv faib transformers. Chav tsev no kuj tau nruab nrog NLTC tsis muaj -load kais hloov pauv, thiab nws qhov kev rho tawm polarity thiab Ii0 vector pawg ua kom cov theem sib dhos nrog 50 kVA lub teeb ncej transformer los ntawm tib qhov kev txiav txim. Ua ke, ob lub tshuab hloov pauv no muaj kev ua haujlwm siab, poob qis, thiab kev hloov pauv tau zoo, xa lub zog muaj kev nyab xeeb thiab txhim khu kev qha rau North American tis network.

1.2 Technical Specification

100kVA lub teeb ncej transformer specification thiab cov ntaub ntawv ntawv

1.3 Cov duab kos

100kVA ib theem ncoo mounted transformer daim duab kos duab thiab loj.

02 Kev tsim khoom

2.1 Core

2.2 Cua txias

HV winding yog tsim los nrog concentric txheej siv high -purity tooj liab conductor, insulated nrog enamel txheej rau superior dielectric zog thiab thermal kuj mus txog 105 degree. Lub LV winding siv txhuas sawb, muab thaj chaw loj, ua kom txias dua, thiab ruaj khov hluav taws xob ua haujlwm nyob rau hauv cov xwm txheej hnyav.

 

2.3 Tank

Lub tank yog tsim los ntawm cov hlau me me nrog lub cev cylindrical thiab lub hau npog uas tshem tau, ua tiav hauv RAL7035 xim. Tsis muaj kev tshuaj xyuas lossis qhib kev pabcuam. Ob lub zog mounting brackets nrog lub thickness tsawg kawg yog 3.4 hli yog welded rau lub tank. Cov xaus yog khoov rau ib tug haum haum. Tag nrho cov welds yuav tsum sib npaug thiab du. Lawv yuav tsum tsis muaj qhov thiab yuav tsum tau hauv av tom qab vuam.

 

2.4 Kev sib dhos zaum kawg

1. Winding Assembly:Xaub lub HV / LV windings mus rau hauv cov tub ntxhais laminated, kom ntseeg tau tias kev sib raug zoo thiab kev ruaj ntseg ntawm rwb thaiv tsev.
2. Kev sib txuas hluav taws xob:Txuas winding coj mus rau kais hloov pauv, bushings, thiab lwm yam khoom, ces ruaj ntseg thiab insulate cov pob qij txha.
3. Core-Coil ziab:Muab cov khoom sib dhos ua ke (core + windings) rau hauv qhov cub kom qhuav rau lub tshuab nqus tsev kom tshem tawm cov dej noo.
4. Tank Installation:Nqa cov khoom ua haujlwm qhuav rau hauv lub tank, tso nws kom ruaj ntseg, thiab xyuas kom muaj kev rwb thaiv tsev los ntawm cov phab ntsa tank.
5. Accessory Mounting:Txhim kho bushings, siab nyem valve thiab lwm yam khoom siv, tom qab ntawd xyuas seb cov dej xau.
6. Roj Sau & Teeb:Lub tshuab nqus tsev- sau nrog cov roj insulating, degas, thiab tso cai rau kev daws teeb meem ua ntej kuaj cov roj qib thiab lub zog dielectric.

04 Packing thiab Shipping

05 Site thiab Summary

Lub 100 kVA ib qho -theem ncej- mounted transformer yog siv nyob rau hauv North American overhead tis networks. Nws muab lub zog txhim khu kev qha rau cov tsev thiab cov lag luam me. Nws siv ONAN roj txias. Cov windings yog ua los ntawm siab - zoo tooj liab thiab txhuas. Lub tank muaj zog thiab kaw rau kev siv ntev. Nws tsis muaj -load kais hloov pauv rau kev hloov pauv voltage. Lub transformer khiav ruaj khov thiab zoo. Scotech ua rau txhua qhov hloov pauv kom zoo. Txhua chav ua tau raws li cov qauv thoob ntiaj teb.
