01 General
1.1 Project Description
Qhov no yog 50 kVAib leeg-theem ncej-mounted faib transformernruj me ntsis ua raws li IEEE C57.12.20 tus qauv. Nws yog dav siv nyob rau hauv North American tis networks, feem ntau ntsia rau hauv 13.8 kV grounded -wye systems, qhov twg lub transformer yog txuas nrog theem- rau - nruab nrab ntawm 7.97 kV thiab muab ib tug txhim khu kev qha 120/240 V phua- theem tso zis rau thaj chaw thiab lub teeb coj mus muag daim ntaub ntawv.
Lub 50 kVA transformer ntawm lub hwj chim ncej txais ib qho amorphous hlau core, uas zoo heev txo tsis muaj -load poob rau tsuas yog 0.043 kW. Nws muab lub zog zoo heev -txuag kev ua tau zoo txawm tias lub teeb load. Nrog rau qhov ntsuas impedance ntawm 2.1%, lub transformer muaj qhov zoo voltage tswj thiab, ua ke nrog nws ± 2 × 2.5% tsis muaj-load kais hloov pauv, ua kom ruaj khov theem nrab voltage hauv ± 5% ntawm nominal.
Nws cov qauv tsim muaj xws li ONAN ntuj txias, aluminium windings, thiab ntxiv polarity, nrog vector pawg Ii6. Cov yam ntxwv no ua rau lub transformer compact. Nws ua tau zoo thiab txhim khu kev qha rau ncej-mounted siv. Lub unit muaj ib tug surge arrester tus thawj coj. Qhov no ua rau nws yooj yim ntxiv cov khoom siv tiv thaiv.
Lub transformer muaj tsawg losses. Nws ua haujlwm nrog kev ua haujlwm siab. Nws kuj yoog tau zoo rau cov kev xav tau sib txawv. Qhov no ua rau nws yog qhov kev xaiv zoo rau cov tshuab hluav taws xob niaj hnub.

02 Kev tsim khoom
2.1 Core
Cov ncej-mounted transformernta amorphous hlau core, ua los ntawm cov hlau, boron, silicon, nickel, thiab carbon. Piv nrog rau cov pa txias- dov silicon steel, cov tub ntxhais no yog isotropic, nyias nyias (0.03 hli), thiab muaj hluav taws xob tiv taus siab, txo qis kev poob tam sim no. Nws ua tau zoo heev uas tsis muaj-load poob (0.043 kW) thiab load poob (0.5 kW), muab kev ua haujlwm siab, kev tsim khoom yooj yim, thiab eco- ua haujlwm zoo.
2.2 Cua txias
Peb ib leeg -theem ncej-mounted transformers feature low-voltage foil coils thiab high-voltage wire coils. Cov neeg siv khoom xaiv aluminium LV coils tau txais txiaj ntsig los ntawm kev txo qhov hnyav thiab tus nqi, thaum tswj kev sib piv kev ntseeg tau thiab lub neej ua haujlwm rau tooj liab. High-voltage wire coils xyuas kom muaj qhov sib npaug ntawm qhov hluav taws xob thiab qhov hluav taws xob.
2.3 Tank
Qhov no ib zaug -theem cylindrical roj tank yog tsim los ntawm cov hlau me me, nrog lub hau thiab hauv qab tsim los ntawm cov txheej txheem nyias - daim ntawv. Nruab nrog ob lub HV bushings ntawm lub hau thiab peb lub LV eyebolt bushings ntawm lub sidewall, nws tag nrho cov qauv tsim kom muaj kev ruaj ntseg zoo dua thiab kev ua haujlwm zoo.
2.4 Kev sib dhos zaum kawg
Yuav ua li cas rau nruab lub kauj thiab lub qhov txhab qhov txhab: Ua ntej, nteg thawj C-core ca (qhib lub ntsej muag zoo li "U"). Coj lub kauj thiab lub tes tsho tag nrho nws lub hauv paus qhov rau ntawm ib ceg ntawm cov tub ntxhais, thawb nws mus rau hauv qab. Siv qhov thib ob C-core, kho nws cov kev txiav kom meej nrog thawj tus tub ntxhais txiav. Maj mam kaw nws kom txog thaum ob qhov sib xyaw ua ke. Nruab rau saum thiab hauv qab clamping daim hlau, ntxig rau cov ntsia hlau ntev.
