01 General
1.1 Project Description
250 kVA peb theem ncoo mounted transformer tau xa mus rau Guyana xyoo 2024. Lub zog ntsuas ntawm lub transformer yog 250 kVA nrog ONAN txias. Qhov siab voltage yog 13.8 kV nrog ± 2 * 2.5% tapping ntau (NLTC), qhov tsawg voltage yog 0.22y / 0.127 kV, lawv tsim ib pawg vector ntawm Dyn11.
CovPad-Mounted Transformeryog lub hauv paus ntawm niaj hnub, muaj kev nyab xeeb, thiab txhim khu kev qha hluav taws xob hauv av. Tsim los rau kev ua tau zoo thiab kev nyab xeeb rau pej xeem, qhov compact, hauv av- theem chav tsev yog tsim los nqis siab - hluav taws xob hluav taws xob mus rau qib uas siv tau los ntawm cov neeg nyob ib puag ncig, cov chaw lag luam, thiab cov chaw tsim khoom. Tsis zoo li ib txwm ncej-mounted transformers, nws tag nrho cov nyob rau hauv, tamper-resistant steel vaj tse ruaj ntseg muaj tag nrho cov nyob Cheebtsam, ua rau nws yog ib qho kev xaiv zoo tagnrho rau tej thaj chaw uas pej xeem muaj kev txhawj xeeb. Cov qauv tsim muaj zog tiv thaiv ib puag ncig cov ntsiab lus, kev ua phem, thiab kev sib cuag tsis sib haum, ua kom cov kev pabcuam tsis cuam tshuam thiab txhim kho kev nyab xeeb rau zej zog.
Ib qho txiaj ntsig tseem ceeb ntawm Pad-Mounted Transformer yog nws cov hneev taw me me thiab zoo nkauj yooj yim. Nws yog discreetly ntsia rau ntawm lub pob zeb hauv av theem, yooj yim sib xyaw rau hauv nws ib puag ncig lossis raug tshuaj xyuas nrog kev tsim kho kom zoo nkauj. Qhov kev tsim no tsis tsuas yog khaws cia qhov pom kev pom ntawm thaj chaw tab sis kuj tso cai rau cov neeg siv hluav taws xob muaj kev nyab xeeb thiab yooj yim rau kev saib xyuas thiab tswj kev thauj khoom.
Los ntawm lub zog ntawm lub nroog ntse mus rau kev sib koom ua ke cov khoom siv hluav taws xob tauj dua tshiab, Pad-Mounted Transformer sawv ua tus ntsiag to, txhim khu kev qha, thiab muaj txiaj ntsig tus neeg saib xyuas ntawm daim phiaj hluav taws xob, xa hluav taws xob rau qhov xav tau- nyab xeeb thiab seamlessly.

02 Kev tsim khoom
2.1 Core
Lub ncoo no -mounted transformer nta lub compact peb-theem, peb-limb core ua los ntawm laminated silicon steel. Tus qauv tsim muab txoj hauv kev zoo sib nqus rau lub ntsiab flux thaum tso cai xoom-flux rov qab los ntawm huab cua, ua rau muaj qhov muaj zog thiab qhov chaw- txuag chav.
2.2 Cua txias
Cov windings siv tooj liab rau ob qhov qis-voltage thiab siab-voltage seem. Qhov qis-voltage winding yog ntawm cov ntawv ci tsim, muab cov axial luv luv- lub zog hluav taws xob thiab ua kom muaj cua sov zoo. Conversely, lub siab -voltage winding ntiav ib txheej- qhov txhab tsim nrog puag ncig los yog duab plaub hlau nplaum, muab qhov tsim nyog voltage endurance thiab yooj nyob rau hauv lem kev npaj. Qhov kev sib xyaw ua ke ntawm cov ntawv ci thiab txheej - cov txheej txheem kev kho mob ua rau muaj kev sib koom ua ke, kev cog lus, thiab txhim khu kev qha coil.
2.3 Tank
Lub tank transformer yog tsim los ntawm cov hlau me me, muab lub zog thiab tus nqi -cov ntaub ntawv zoo. Nws yog hermetically kaw kom ntseeg tau tias cov roj insulating sab hauv tseem cais tawm ntawm cov dej noo thiab cov kab mob. Cov txheej txheej sab nrauv uas siv tau los tiv thaiv ib puag ncig hnyav, ua rau nws haum rau ntev - kev pabcuam sab nraum zoov.
2.4 Lub Rooj Sib Tham Kawg
Kev sib dhos zaum kawg ua ke nrog cov tub ntxhais - thiab - coil unit rau hauv lub tank me me, uas tom qab ntawd tau ntim cov roj purified dielectric. Tag nrho cov kev sib txuas sab hauv tau ruaj ntseg, thiab cov khoom siv sab nraud xws li cov khoom sib txuas hauv nruab nrab, kev txiav tawm thawj zaug (xws li lub luj tshib lossis bushings), cov cuab yeej siv siab, thiab cov hlua hauv av tau teeb tsa. Lub tank yog hermetically kaw, thiab tag nrho lub tsev yuav raug kuaj nruj kom ntseeg tau tias kev ua haujlwm zoo, kev nyab xeeb, thiab kev ntseeg tau ua ntej tau txais kev pom zoo rau kev pabcuam.
03 Kev Xeem
Cov kev ntsuam xyuas suav nrog cov khoom siv niaj hnub: ntsuas qhov ntsuas qhov ntsuas qhov ntsuas (max tsis sib npaug li 1.57%), qhov ntsuas qhov sib piv (kev sib txawv -0.07% rau -0.05%), kev ntsuas theem (paub Dyn11), tsis muaj kev poob qis thiab ntsuas tam sim no (0.450kW, 0.76%), load thiab voltage 0.54kW (3. poob, 3.93% impedance, 99.04% efficiency), thov voltage test (34kV rau HV, 10kV rau LV, 60s txhua yam uas tsis muaj voltage vau), induced voltage withstand test (27.6kV, 150Hz, 48s, tsis muaj voltage vau), to test (20kPa rau 12h), rwb thaiv tsev roj thiab hluav taws xob ntsuas. (55.13 kV). Txhua qhov ntsuas ntsuas tau raws li qhov yuav tsum tau ua, ua rau "Pass" xaus. Daim ntawv tshaj tawm tsuas yog siv tau nrog kos npe ntawm tus neeg kuaj, tus neeg pov thawj, thiab tus neeg pom zoo; Kev tawm tsam yuav tsum xa tuaj hauv 7 hnub tom qab tau txais, thiab tsis pub luam tawm yam tsis muaj Scotech daim ntawv tso cai.
