01 General
1.1 Project Background
150 kVA ib theem ncej mounted transformer tau xa mus rau Canada nyob rau hauv 2024. Lub zog ntsuas ntawm lub transformer yog 150 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 19.92 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.12 / 0.24 kV, lawv tsim ib pawg vector ntawm Ii0.
Ib zaug xwb -theem ncej mounted transformer yog ib hom ntawm transformer feem ntau siv nyob rau hauv tis systems, feem ntau ntsia rau cov nqi hluav taws xob ncej. Nws lub luag haujlwm tseem ceeb yog hloov hluav taws xob hluav taws xob hluav taws xob siab rau hauv qis qis kom muaj kev nyab xeeb thiab siv tau zoo los ntawm cov neeg siv khoom. Qhov no transformer yog dav siv nyob rau hauv cov nyob deb nroog thiab nroog faib network, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas tsis tshua muaj hwj chim xav tau, xws li tej thaj chaw, kev ua liaj ua teb, thiab me me industries. Txij li cov ncej- mounted transformers tau nruab rau ntawm cov khoom siv hluav taws xob, lawv txuag tau qhov chaw hauv av thiab txo cov nqi vaj tse uas cuam tshuam nrog kev tso cable. Nruab nrog cov cuab yeej tiv thaiv, cov transformers no tuaj yeem tiv thaiv luv luv Circuit Court, overloads, thiab lwm yam txhaum, txhim kho kev ua haujlwm kev nyab xeeb thiab kev ntseeg siab.

02 Kev tsim khoom
2.1 Polarity
Polarity yuav tsum yog additive rau tag nrho ib zaug xwb -theem transformers nyob rau hauv qhov ntau thiab tsawg 200 kVA thiab me me uas muaj siab -voltagewindings 8660 V thiab hauv qab, Polarity yuav tsum tau rho tawm rau tag nrho lwm cov tib -theem transformers.
2.2 Cua txias
Thawj kauj tau txais qhov hluav taws xob input, thaum lub kauj thib ob tso tawm qhov hloov pauv hloov pauv. Nyob ntawm qhov sib piv ntawm cov coils, lub transformer tuaj yeem nce lossis nqis qis dua qhov voltage. Cov coils tsis tsuas yog hloov voltage tab sis kuj kis tam sim no. Qhov loj ntawm cov tam sim no nyob rau hauv lub hauv paus thiab theem nrab coils yog inversely proportional rau lawv cov lem, yooj yim hloov tam sim no. Tus tsim ntawm cov coils yuav tsum xav txog impedance txuam nrog lub load kom ntseeg tau tias lub zog siab tshaj plaws thiab kev ua haujlwm zoo tshaj plaws.
2.3 Tank grounding
Qhov qis-voltage grounding provisions yuav tsum muaj steel pad nrog 1/2-in-13-NC tapped qhov, 11 mm (0.44 in) tob. Cov threads shalbe tiv thaiv los ntawm corrosion-resistant flanged khob ntsia rau hauv threaded qhib ntawm lub unsived av ncoo.Cov transformer npog yuav tsum tau hluav taws xob bonded externally rau lub tank, qhov chaw ntawm daim ntawv cog lus yuav tsum tsis txhob cuam tshuam nrog lub lifting lugs.
2.4 xob laim ntes mounting muab
Kev npaj: Ntxuav thiab tshuaj xyuas tag nrho cov khoom, nrog rau lub tsev transformer, core, windings, rwb thaiv tsev cov ntaub ntawv, thiab cov roj txias.
Core Installation: Sib sau ua ke thiab ruaj ntseg cov tub ntxhais mus rau hauv qab ntawm lub tsev, ua kom ruaj khov.
Winding Installation: Nruab qhov siab -voltage thiab low-voltage windings mus rau hauv cov tub ntxhais raws li cov qauv tsim tshwj xeeb, ua kom muaj kev tiv thaiv zoo ntawm cov windings.
Rwb thaiv tsev roj filling: Muab cov roj rwb thaiv tsev tso rau hauv lub tsev, kom ntseeg tau tias nws tag nrho submerges lub windings thiab displaces tej huab cua.
Tsev Sealing: Txhim kho thiab muab khi rau sab sauv ntawm lub tsev, kom ntseeg tau tias cov khoom siv sab hauv muaj kev tiv thaiv los ntawm ya raws thiab paug.
03 Kev Xeem
Lub kaw lus yuav tsum tau kuaj yuav tsum yog ib chav tsev tshiab, ua tiav nrog nws cov tub ntxhais thiab coil, bushings, thiab lwm yam. Qhov kev ntsuam xyuas yuav tsum tau ua nyob rau ntawm qhov kub thiab txias nrog qhov pib sab hauv siab ntawm 42 kPa mus rau 48 kPa (gauge) (6 psigto 7 psig). Lub transformer raug kuaj yuav tsum tau ruaj ntseg los ntawm nws cov lug txhawb nqa thiab mounted clear ntawm lub ntiaj teb. Cov kev xeem yuav tsum tau ua raws li lEEE Std C37.40 thiab lEEE Std C37.41 yuav tsum ua raws. Lub testcurrent yuav tsum symmetrical. Ib lub thawv tshiab yuav tsum tau siv rau txhua lub luag haujlwm kuaj, Lub luag haujlwm kuaj yuav tsum muaj ob qhov kev xeem. Qhov kev sim thib ob yuav tsum ua kom tiav los ntawm kev rov siv dua, "raws li tau teev tseg los ntawm cov chaw tsim khoom," tag nrho cov khoom qub hauv lub thawv. Cov kev npaj yuav tsum tau ua rau kev tso pa tawm kom muaj kev nyab xeeb txhua qhov kev siab sab hauv uas tseem tshuav tom qab txhua qhov kev sim.

4.1 Cov cuab yeej tiv thaiv siab
Cov cuab yeej siv siab ntau feem ntau muaj cov diaphragm frangible los yog lub siab - qhib qhov cua npog ntsia rau ntawm lub tank transformer. Nyob rau hauv qhov kev tshwm sim ntawm ib tug loj heev sab hauv hluav taws xob txhaum, roj tsim sai ua rau ib tug sai li sai tau nce siab nyob rau hauv lub tank. PRD yog tsim los rau rupture los yog qhib ntawm lub predetermined siab, yog li instantaneously thiab ruaj ntseg venting lub siab - siab gases thiab kub decomposition khoom rau cov huab cua. Qhov kev tso tawm tswj hwm no tiv thaiv kev puas tsuaj loj ntawm lub tank loj, txo qis qhov phom sij phom sij, thiab pab tiv thaiv cov cuab yeej nyob ib sab. Cov cuab yeej siv feem ntau suav nrog tus chij lossis qhov taw qhia uas pom tau mus ncig thaum lub sijhawm ua haujlwm kom pom tias muaj xwm txheej siab tshwm sim.
4.2 cog
Cov plooj (porcelain bushing) ntawm lub ncoo-mounted transformer yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob uas ua haujlwm rau qhov hloov pauv rau lub tshuab hluav taws xob sab hauv hluav taws xob kom tawm ntawm lub tank hauv av. Tsim los ntawm siab - lub zog, glazed porcelain, nws muab lub zog dielectric zoo heev los tiv thaiv lub zog hluav taws xob los ntawm cov vaj tsev hauv av, txawm tias nyob rau hauv cov dej ntub thiab cov kab mob. Nws cov yam ntxwv elongated, ribbed lossis skirted tsim ua rau kom qhov chaw nkag mus deb, tiv thaiv flashover. Lub bushing los ua ke yog hermetically kaw rau lub tank kom muaj kev ncaj ncees ntawm cov roj sab hauv thiab feem ntau muaj qhov sib txuas ntawm lub davhlau ya nyob twg (xws li lub bolted ncoo lossis cable accessory interface) rau kev txuas mus rau hauv av los yog nyiaj siv ua haujlwm.
