01 General
1.1 Project Description
Xyoo 2025, 50 kVA ib zaug -theem ncej- mounted transformer tau raug xa mus rau Canada rau kev siv nyob rau hauv cov neeg nyob deb nroog thiab ib nrab- hauv nroog faib network. Lub tsev kawm ntawv ua haujlwm pab pawg me me thiab thaj chaw hauv zos lossis kev lag luam thauj khoom siv los ntawm 13.8 kV nyiaj siv ua haujlwm. Tsim los tswj cov kev xav tau ntawm lub caij nyoog siab tshaj plaws thiab nquag cua daj cua dub, lub tshuab hloov ua kom ruaj khov, muaj zog txaus txawm tias nyob hauv ib puag ncig hnyav.
Ua rau CSA C2.2-06 tus qauv, chav tsev nta ONAN txias, 13.8 kV / 0.347 kV ratings, Ii6 vector pawg, thiab Additive polarity. Nws suav nrog NLTC kais hloov pauv nrog ± 2 × 2.5% ntau yam rau kev hloov pauv qhov tseeb. Nrog aluminium windings, 2.3% impedance, thiab 98.35% kev ua haujlwm, nws muaj kev ua tau zoo nrog kev poob qis thiab kev saib xyuas yooj yim.
Mounted ntawm tus qauv faib ncej nrog lub fused thawj txiav tawm, surge arrester, thiab grounding system, no transformer muab ib tug muaj kev ruaj ntseg thiab saj zawg zog faib kev daws teeb meem. Qhov zoo tshaj plaws rau kev siv hluav taws xob nyob deb nroog, kev sib tham hauv xov tooj, thiab cov khoom siv me me, nws ua ke ua haujlwm ntev, kev ntseeg tau, thiab kev tswj hluav taws xob zoo heev hauv ib qho kev tsim sab nraum zoov.

02 Kev tsim khoom
2.1 Core
Qhov no transformer nta ib tug siab heev lub qhov txhab tsim, qhov twg cov tub ntxhais yog tsis tu ncua raug mob los ntawm siab -permeability txias- dov silicon steel strips los ua ib tug seamless kaw magnetic Circuit Court. Piv rau cov pa laminated cores, lub qhov txhab qhov txhab muaj qis dua tsis muaj -load poob, txo suab nrov, tsis sib xws flux tis, thiab txhim khu kev tiv thaiv luv luv.
2.2 Cua txias
Lub tshuab hluav taws xob no siv thev naus laus zis thev naus laus zis: qhov qis -voltage (LV) sab siv cov ntawv ci winding rau superior tam sim no - nqa peev xwm thiab cua sov dissipation, zoo txo eddy tam sim no poob; thaum lub siab -voltage (HV) sab txais precision txheej hlau winding los xyuas kom meej rwb thaiv tsev lub zog thiab voltage stability. Qhov no "foil-mob LV + xaim-mob HV" ua ke tsim ua tiav kev ua haujlwm zoo, compactness thiab luv luv -circuit resistance, ua rau nws zoo tagnrho rau kev thov sab nraum zoov ncej- mounted daim ntaub ntawv.
2.3 Tank
Qhov no transformer siv lub hermetically kaw cylindrical tank tsim los ntawm precision roller dabtsi yog khoov txheej txheem. Ua los ntawm premium txias-rolled steel, lub tank yog zoo li tus CNC dov tshuab nrog tsuas yog ib tug precision laser -welded longitudinal seam, nruj me ntsis soj ntsuam los ntawm X- rays thiab xau kuaj. Lub cylindrical tsim tsis tsuas yog compact aesthetics tab sis kuj tshwj xeeb mechanical zog thiab tshav kub dissipation, featuring lub sab hauv roj guiding raws rau npaum ntuj txias. Nrog triple - txheej tiv thaiv - txheej txheej corrosion (primer + epoxy intermediate + polyurethane topcoat), nws tiv taus qhov chaw hnyav xws li ntsev tsuag thiab kua qaub los nag.
2.4 Lub Rooj Sib Tham Kawg
1. Winding Assembly:Xaub lub HV / LV windings mus rau lub laminated core, kom ntseeg tau tias kev sib raug zoo thiab rwb thaiv tsev clearance.
2. Kev sib txuas hluav taws xob:Txuas winding ua rau kais hloov pauv, bushings, thiab lwm yam khoom, ua raws li kev kho kom nruj thiab rwb thaiv tsev.
3. Core-Coil ziab:Muab cov khoom sib dhos ua ke rau hauv qhov cub kom qhuav kom tshem tawm cov dej noo thiab txhim kho kev ua haujlwm ntawm rwb thaiv tsev.
4. Tank Installation:Nqa cov khoom ua haujlwm qhuav rau hauv lub tank, ruaj ntseg rau hauv txoj hauj lwm, thiab kaw lub tank npog.
5. Accessory Mounting:Nruab bushings, ntes, siab nyem valve.
6. Roj Sau & Sealing:Lub tshuab nqus tsev- sau nrog cov roj insulating, xyuas cov roj qib thiab sealing tom qab kev daws teeb meem, thiab ua qhov kev ntsuam xyuas zaum kawg kom tiav.

04 Packing thiab Shipping
4.1 Ntim
Lub tshuab hloov pauv tau ntim rau hauv ib lub thawv ntim ntoo uas tsim los nrog cov dej noo- cov ntaub ntawv pov thawj plywood, featuring kev cai- molded foam inserts thiab anti- vibration brackets kom immobilize chav tsev thaum lub sij hawm thauj mus los. Sab nrauv yog coated nrog cov kua roj vanish tsis muaj dej thiab ntxiv dag zog nrog cov hlua hlau, nruab nrog hnyav- lub luag haujlwm nqa nqa ntawm txhua lub ces kaum. Ua ntej packing, lub transformer undergoes lub nqus tsev vacuum qhuav thiab puv nrog 0.02MPa nitrogen. Cov cim thoob ntiaj teb tseem ceeb rau qhov nruab nrab ntawm lub ntiajteb txawj nqus, "Keep Dry" thiab "Side Up" yog tso tawm. Muaj ntawv pov thawj rau ISTA 3A cov qauv, lub ntim nrog 2000km kev thauj mus los thiab thoob ntiaj teb hiav txwv freight tej yam kev mob.
4.2 Shipping
Cov transformers yuav raug xa mus raws li CIF (Cov Nqi, Kev Pov Hwm, thiab Freight) cov nqe lus, tawm ntawm Ningbo chaw nres nkoj mus rau Chaw nres nkoj ntawm Montreal. Cov khoom xa tuaj yuav raug thauj los ntawm cov thawv ntim khoom hauv hiav txwv, nrog rau kev nyab xeeb thiab kev tiv thaiv kev tiv thaiv (tiv thaiv- poob siab, ya raws- pov thawj, thiab tiv thaiv- xeb) kom muaj kev nyab xeeb ntev - kev thauj mus los hauv hiav txwv. Tus neeg muag khoom yuav npaj kev thauj mus los hauv hiav txwv thiab muab kev tuav pov hwm marine (Tag nrho cov kev pheej hmoo), suav nrog kev puas tsuaj vim muaj xwm txheej lossis kev puas tsuaj ntuj tsim thaum caij tsheb npav. Thaum tuaj txog ntawm Montreal, tus neeg yuav khoom yog lub luag haujlwm rau kev lis kev cai thiab kev thauj mus los hauv av ntxiv.
05 Kev saib xyuas ntawm ncej-mounted transformers
Kev tuav tus ncej-mounted transformers tsis yog hais txog ticking tawm ntawm daim ntawv teev npe. Nws yog hais txog kev ua kom txhua chav ua haujlwm txuas ntxiv kom nyab xeeb, ua tau zoo, thiab ntev li ntev tau. Kev nyab xeeb, kev cia siab, thiab sib xws - lawv txhua tus nyob ntawm cov ntsiab lus me me. Qee zaum, cov ntsiab lus uas lwm tus saib dhau.
(1) Kev Tshawb Fawb Txog Kev Pom Zoo tsis tu ncua
Thawj kauj ruam yog qhov yooj yim tshaj plaws - tsuas yog saib. Kev soj ntsuam ceev feem ntau qhia ntau dua li daim ntawv tshaj tawm. Tshawb xyuas cov roj xau, corrosion, lossis dents. Roj stains tej zaum yuav qhia ib tug phem foob; xeb tuaj yeem txhais tau tias lub tank maj mam poob nws lub zog. Txhim kho cov no thaum ntxov- ua ntej lawv loj hlob mus rau cov teeb meem loj dua - txuag lub sijhawm thiab khoom siv.
(2) Roj Qib thiab Kev Ntsuas Zoo
Transformer roj yog nws cov ntshav. Nws txias, insulates, tiv thaiv. Cov roj tsawg? Qhov ntawd yog tus chij liab. Tsaus lossis huab roj? Kuj teeb meem. Scotech qhov kev paub qhia tau hais tias kev kuaj roj tsis tu ncua, txawm tias ceev ceev, tiv thaiv feem ntau ntawm cov cua sov ua ntej lawv pib.
(3) Roj Purification
Tam sim no, qee zaum kev tshuaj xyuas tsis txaus. Cov roj yuav zoo li zoo tab sis poob nws cov khoom nyob rau lub sijhawm - ya raws, roj av, cov khoom me me nkag mus rau hauv. Qhov ntawd yog thaum purification los rau hauv. Lub tshuab nqus dej, pom, degassing… me ntsis kev, yog, tab sis tsim nyog. Txhua lub voj voog rov ua kom cov roj lub zog, txuas ntxiv lub neej ntawm transformer.
(4) Kev sib txuas ceev ceev
Loose bolts tsis ua suab nrov, tab sis lawv ua rau muaj teeb meem tiag tiag - arcing, tshav kub kub, tsis ua hauj lwm. Txhua qhov kev sib txuas tseem ceeb: bushings, kais dej, cov ntsiab lus hauv av. Scotech cov pab pawg tu xyuas nruj, rov xyuas dua, thiab nruj dua yog tias xav tau. Nws yog tedious ua hauj lwm, tab sis qhov ntawd yog dab tsi ua rau transformers ciaj sia rau xyoo.
(5) Ntxuav
Plua plav, noog poob, txawm tawm - tej yam me me uas thaiv cov cua ntws thiab cua kub. Thaum lub sij hawm, lub radiator ua tsis taus pa. Yog li, kev ntxuav tsis yog tshuaj pleev ib ce; nws yog ib feem ntawm lub tshuab cua txias. Ib tug huv transformer khiav txias, kav ntev. Yooj yim, tab sis
