01 General
1.1 Project Description
Cov no75 kVA peb-theem ncoo-mounted transformerstau tsim los ntawm Scotech. Lawv raug xa mus rau Tebchaws Meskas hauv 2024. Lawv ua tau raws li IEEE / ANSI cov qauv thiab ua haujlwm zoo nrog North American tis systems. Pem hauv ntej-compartment, tuag-pem hauv ntej tsim tshem tawm qhov chaw nyob thiab muab kev nyab xeeb siab. Nws yog ib qho yooj yim los xyuas thiab tswj, thiab tag nrho cov energized qhov chaw nyob twj ywm kaw thiab insulated.
Lub 75 kVA tuag pem hauv ntej transformer muaj tsib - ceg tub ntxhais ua los ntawm qib siab - qib txias- dov silicon steel los xij nrog cov kauj ruam - ceg tawv pob qij txha. Nws yog tsim los ua kom tau raws li lub zog- cov qauv siv tau zoo thiab muaj 99.03% kev ua haujlwm zoo. Kev txhim kho kev sib nqus hluav taws xob thiab qis- poob aluminium windings pab txo cov khoom siv hluav taws xob. Lawv kuj txuag nyiaj dhau sijhawm thiab tiv thaiv ib puag ncig.
Lub transformer yog tsim los rau 2400/4180Y los yog 13200/22860Y grounded wye systems, ua hauj lwm stably nyob rau hauv ib txwm kev pab cuam. Nws muab kev nyab xeeb thiab muaj txiaj ntsig xa hluav taws xob hauv nroog, kev lag luam, thiab kev lag luam xa tawm, txhawb nruab nrab - thiab qis -voltage voj tshuab thoob plaws North America.

02 Kev tsim khoom
2.1 Core
Lub 75 kVA ncoo-mounted transformer txais yuav tsib -limb core tsim los xyuas kom meej symmetrical magnetic flux paths, tsis tshua muaj suab nrov, thiab txo stray losses. Cov qauv no muab txoj hauv kev kaw rau xoom-flux nyob rau hauv Y-Y kev sib txuas, txhim kho luv luv- lub zog hluav taws xob, thiab tso cai rau lub tank zoo dua qub haum rau lub voj- pub tuag- pem hauv ntej teeb tsa feem ntau siv hauv North American tis network.
2.2 Cua txias
Lub HV thiab LV windings yog ua los ntawm high -conductivity aluminium conductors, kom muaj kev sib npaug ntawm kev ua haujlwm, nqi, thiab kev ua haujlwm thermal. Cov windings siv txheej txheej thiab helical winding txoj kev nrog nruj qhov ntev tolerances kom ua tau zoo heev dielectric zog thiab tsis tshua muaj to reactance. Peb cov kws tshaj lij cov kws ua haujlwm tau txais kev cob qhia los xyuas kom meej tias txhua qhov kev sib tw winding yog ib yam, kev ruaj ntseg, thiab tsis muaj deformation lossis rwb thaiv tsev puas.
2.3 Tank
Tag nrho cov hlau qhov chaw ntawm transformer tank thiab compartments yog huv si huv si thiab pretreated ua ntej pleev xim rau kom muaj zog adhesion thiab corrosion kuj. Rau kev tiv thaiv ntxiv -corrosion kev ua tau zoo, hauv qab 4 ntiv tes ntawm lub tank thiab cov khoom ntim yog coated nrog cov thee-tar epoxy lossis sib npaug hnyav-cov dej tiv thaiv txheej, kom ntseeg tau ntev- lub sij hawm tiv taus noo noo, av, thiab hnyav sab nraum zoov.
2.4 Kev sib dhos zaum kawg
