01 General
1.1 Project Description
3000 kVA peb theem ncoo mounted transformer raug xa mus rau Canada hauv 2025. Lub zog ntsuas ntawm lub transformer yog 3000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 25 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.6Y / 0.347 kV, lawv tsim ib pawg vector ntawm Dyn1.
Pad-mounted transformers yog cov khoom tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no, tsim kom muaj kev nyab xeeb, txhim khu kev qha, thiab muaj txiaj ntsig hloov hluav taws xob hauv nroog, suburban, thiab chaw lag luam. Cov cuab yeej muaj zog, hauv av- qib no yog nyob rau hauv cov khoom siv ruaj khov, tiv thaiv huab cua, tiv thaiv cov khoom tseem ceeb thaum ua kom yooj yim rau kev saib xyuas. Qhov zoo tshaj plaws rau kev siv hluav taws xob hauv av, ncoo- mounted transformers muab cov hneev taw me me, txhim kho kev nyab xeeb, thiab qis- suab nrov ua haujlwm- ua rau lawv zoo meej rau thaj chaw uas muaj kev zoo nkauj thiab qhov chaw yog qhov tseem ceeb. Nrog kev ua haujlwm siab, kev ua haujlwm ntev, thiab ua raws li cov qauv kev lag luam, lawv muab cov khoom siv hluav taws xob thiab cov neeg siv khoom lag luam nrog cov kev daws teeb meem rau kev nqis qis nruab nrab - hluav taws xob hluav taws xob mus rau qib siv tau. Txawm hais tias rau kev tsim kho vaj tse, chaw ua lag luam, lossis kev siv hluav taws xob txuas ntxiv dua tshiab, ncoo-mounted transformers muab kev ua tau zoo uas koj tuaj yeem ntseeg tau.

02 Kev tsim khoom
2.1 Hauv av
Cov terminals hauv av ntawm lub ncoo -mounted transformer yog cov khoom tseem ceeb rau kev tsim kom muaj kev ruaj khov thiab ruaj khov hauv av. Vertically welded ncaj qha mus rau lub transformer tank phab ntsa ntawm ob sab HV thiab LV, cov terminals no yog cov ntsiab lus tseem ceeb. Tom qab ntawd lub tsheb npav tooj liab nruj yog siv los txuas rau ob lub davhlau ya nyob twg, tsim kom muaj kev sib txuas, qis -kev tiv thaiv uas ua kom lub tank tag nrho thiab cov tub ntxhais sib dhos nyob twj ywm ntawm qhov chaw nyab xeeb. Qhov kev tsim no zoo sib txuas rau txhua yam khoom siv hlau, muab txoj hauv kev txhim khu kev qha rau kev ua txhaum tam sim no thiab txhim kho kev nyab xeeb rau ob qho tib si khoom siv thiab pej xeem.
2.2 LV Neutral Bushing (X0)
Lub Low-Voltage Neutral Bushing (X0) ntawm lub ncoo-mounted transformer ua lub hauv paus ntsiab lus rau cov hluav taws xob theem nrab. Nws txuas mus tas li mus rau lub transformer lub tsheb npav hauv av los ntawm tus neeg xyuas pib ntsuas nrog qhov tsim nyog ampacity, kom ntseeg tau tias qhov qis -impedance txoj kev rau qhov txhaum tam sim no thiab muab lub kaw lus ruaj khov nruab nrab. Qhov kev sib txuas tseem ceeb no tsim kom muaj kev nyab xeeb siv rau hauv av hauv av, ua kom cov cuab yeej siv tau zoo thiab txhim kho cov neeg ua haujlwm thiab kev nyab xeeb rau pej xeem.
2.3 Tank
Lub tank yog tsim los nrog qib siab -qib, corrosion-cov hlau tiv taus kom ntseeg tau ntev- lub sijhawm ua haujlwm nyob rau hauv qhov hnyav sab nraum zoov. Featuring ib tug tag nrho kaw tsim nrog precision welds, nws muab kev tiv thaiv zoo heev tiv thaiv ya raws thiab kab mob. Lub tank suav nrog cov txheej txheem tso cua txias fins thiab cov channel los txhim kho cov cua sov kom zoo thaum tswj kev ua haujlwm zoo. Txhim kho kev tsim kho nrog cov nqa nqa thiab cov hnab nqa forklift yooj yim rau kev nyab xeeb kev thauj mus los thiab kev teeb tsa. Sab nrauv tau txais ntau- txheej tiv thaiv txheej txheej rau kev txhim kho huab cua tiv thaiv thiab kev zoo nkauj.
2.4 Lub Rooj Sib Tham Kawg
Kev sib dhos zaum kawg ntawm ncoo-mounted transformers integrates core-coil assemblies, high-voltage bushings, thiab tiv thaiv cov cuab yeej rau hauv ib qho chaw ruaj khov, huab cua tsis zoo. Precision alignment ua kom pom kev sib nqus hluav taws xob ua haujlwm zoo thaum tswj xyuas hluav taws xob kom raug. Cov txheej txheem sib dhos suav nrog kev sim nruj ntawm tag nrho cov khoom, lub tshuab nqus tsev roj filling rau kev rwb thaiv tsev zoo dua, thiab kev pov thawj zoo kawg. Factory- cov thawv sib txuas sib txuas thiab cov kab hluav taws xob tua hluav taws xob muab kev sib txuas yooj yim.
03 Kev Xeem
Dielectric poob qhov tseem ceeb (los yog lub zog muaj zog) xeem:- Lub dielectric poob qhov ntsuas yog siv los ntsuas qhov poob ntawm cov ntaub ntawv rwb thaiv tsev nyob rau hauv lub transformer nyob rau hauv lub zog ntawm hluav taws xob teb, thiab txiav txim siab qhov℃ntawm deterioration ntawm nws cov rwb thaiv tsev kev ua tau zoo. Qhov kev sim no tuaj yeem muab cov lus ceeb toom ntxov txog kev laus, kev puas tsuaj, lossis kev ua haujlwm tsis txaus ntawm cov ntaub ntawv rwb thaiv tsev.
04 lwm
4.1 plaub load break hloov
Lub 4- txoj hauj lwm load hloov ntawm Pad Mounted Transformer yog ib qho tseem ceeb tswj cov khoom ntawm nws cov high-voltage sab, lub luag hauj lwm rau switching fais fab mov hom thiab muaj kev nyab xeeb fais fab rau / tawm. Nws muaj 4 lub xeev ua haujlwm:
Txoj Haujlwm 1 (Qhov Chaw A & B kais tawm): Ua tiav qhov kev sib txuas ntawm qhov siab -voltage fais fab mov thiab lub transformer. Qhov no yog txoj haujlwm nyab xeeb rau kev hloov pauv thaum siv cov khoom siv tu lossis teeb meem.
Txoj Haujlwm 2 (Qhov Chaw A kais rau): Txuas rau feeder kab A (input kab A). Lub transformer rub lub zog khiav hauj lwm los ntawm daim phiaj hluav taws xob los ntawm cov kab A.
Txoj Haujlwm 3 (Qhov Chaw B coj mus rhaub rau): Txuas rau feeder kab B (input kab B). Lub transformer rub lub hwj chim los ntawm feeder kab B, thiab txoj hauj lwm no feem ntau yog siv los ua lub hwj chim thaub qab.
Txoj Haujlwm 4 (Qhov Chaw A & B coj mus rhaub rau): Txuas ob lub feeder kab A thiab B ib txhij, tsim lub voj voog fais fab kev teeb tsa.
4.2 lub valve
Lub qhov dej ntws tawm ntawm lub ncoo-mounted transformer, feem ntau nyob ntawm qhov qis tshaj ntawm lub tank, yog ib qho tseem ceeb rau kev saib xyuas thiab kev nyab xeeb. Nws tso cai rau kev tswj dej ntawm cov roj insulating rau lub hom phiaj xws li kev tshuaj xyuas sab hauv, kho, lossis qhov kawg decommissioning. Nws tus qauv tsim tiv thaiv cov dej ntws tsis zoo thiab ua kom muaj kev nyab xeeb, qhia cov roj ntws mus rau hauv cov hlab ntsha, ua kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
05 Site thiab Summary
Txawm hais tias rau kev hloov kho hauv nroog hauv nroog lossis kev txhawb nqa chaw ua si hauv chaw ua haujlwm, peb cov pad mounted transformers xa cov kev daws teeb meem ruaj khov, hloov pauv hloov pauv- txhawb nqa los ntawm cov yam ntxwv zoo li 4- txoj haujlwm thauj khoom hloov (rau kev siv hluav taws xob ntau yam) thiab huab cua- tiv taus, siab - tiv thaiv enclosures. Tus neeg siv khoom siv hluav taws xob hauv cheeb tsam tau sau tseg tias: "Cov chav no tau sib xyaw ua ke hauv peb lub voj voog sib txuas; qhov hloov pauv tau yooj yim ua haujlwm thiab 12+ lub hlis ua txhaum- lub sijhawm ua haujlwm pub dawb txiav peb cov sijhawm saib xyuas ntawm qhov chaw los ntawm 20%.
Peb npaj txhij los muab cov kev teeb tsa thiab kev txhawb nqa puv -lub neej- lub voj voog, ua kom koj lub zog ua haujlwm zoo thiab ua haujlwm zoo.
