150 KVA Pad Mount Transformer-13.2/0.208 KV|USA 2025

01 General

1.1 Project Description

150 kVA peb theem ncoo mounted transformer tau xa mus rau Tebchaws Meskas hauv xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 150 kVA nrog ONAN txias. Qhov siab voltage yog 13.2D kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov tsawg voltage yog 0.208GrdY / 0.12 kV, lawv tsim ib pawg vector ntawm Dyn1.

Lub ncoo no -mounted transformer yog tus kheej kiag li-muaj, subsurface-hom faib transformer tsim los rau kev txhim khu kev qha, nyab xeeb, thiab muaj zog xa hluav taws xob hauv kev siv hluav taws xob, kev lag luam, thiab kev lag luam. Engineered rau kev teeb tsa ncaj qha rau ntawm lub pob zeb hauv av, nws muaj cov kev daws teeb meem zoo thiab kev cog lus rau kev nqis qis nruab nrab ntawm qhov hluav taws xob mus rau qhov tsis tshua muaj hluav taws xob siv tau, ua qhov tseem ceeb ntawm cov hluav taws xob faib hluav taws xob.

Tsim los ntawm lub tank zoo stainless hlau, chav tsev no muab kev tiv thaiv corrosion tshwj xeeb, ua kom ntev - lub sij hawm kev ncaj ncees thiab kev saib xyuas - lub neej sab nrauv dawb txawm nyob rau hauv ib puag ncig hnyav lossis ntug hiav txwv. Nws qhov kev ua tau zoo siab tshaj -kev ua tau zoo yog pom los ntawm cov lej poob qis, nrog qhov tshwj xeeb tsis muaj -load poob ntawm 373W thiab tag nrho cov khoom poob ntawm 1163W, txhais ncaj qha rau hauv kev txuag hluav taws xob tseem ceeb thiab txo cov nqi khiav lag luam dhau ntawm lub tshuab hluav taws xob lub neej.

Tshaj li qhov ua tau zoo, qhov hloov pauv no tau tsim rau kev tiv thaiv siab tshaj plaws thiab kev txawj ntse ua haujlwm. Nws tau nruab nrog Internal Fault Detector (IFD), uas muab kev ceeb toom ntxov thiab kev tiv thaiv kev ua txhaum ntawm sab hauv, txhim kho kev nyab xeeb rau ob qho tib si cov khoom siv thiab cov pej xeem. Rau kev tiv thaiv kev tiv thaiv qis qis thiab kev hloov pauv yooj yim, kev sib xyaw ua ke Low-Voltage Circuit Breaker suav nrog. Tsis tas li ntawd, txhawm rau tiv thaiv lub tshuab hluav taws xob rwb thaiv tsev los ntawm kev puas tsuaj hluav taws xob tshwm sim los ntawm xob laim lossis hloov cov xwm txheej, High-Voltage Surge Arresters yog tus qauv haum rau sab xub ntiag.

02 Kev tsim khoom

2.1 Cov

Qhov tsawg-voltage Circuit Court breaker rau pad mounted transformers yog ntsia rau ntawm lub transformer qis-voltage sab, ua ib qho tseem ceeb tiv thaiv thiab tswj cov khoom siv rau kev faib khoom. Nws ceev nrooj ntes thiab cuam tshuam cov overloads, luv luv Circuit Court, thiab lwm yam tsis xws luag tam sim no tej yam kev mob uas muaj siab responsiveness, tiv thaiv kev puas tsuaj rau lub transformer, cov khoom downstream, thiab daim phiaj fais fab. Featuring robust kev tsim kho, txhim khu kev qha tawg muaj peev xwm, thiab huab cua- tiv taus tsim los hloov mus rau sab nraum zoov kev ua haujlwm ib puag ncig, nws txhawb ob qho tib si phau ntawv thiab xaiv hluav taws xob ua haujlwm rau kev saib xyuas yooj yim thiab kev tswj hwm. Los ntawm kev ua kom muaj kev nyab xeeb tam sim no thiab kev sib cais ceev ceev, qhov hluav taws xob hluav taws xob no txhim kho tag nrho kev ruaj ntseg thiab kev nyab xeeb ntawm lub ncoo mounted transformer hauv nroog, kev lag luam, thiab kev lag luam hluav taws xob faib hluav taws xob scenarios.

2.2 TSI

Integrated Fault Detector (IFD) nyob rau hauv lub ncoo no -mounted transformer yog ib qho kev saib xyuas zoo tsim los txhim kho kev ntseeg tau thiab kev nyab xeeb. Nws tsis tu ncua saib xyuas cov haujlwm tseem ceeb xws li lub siab sab hauv, qib dej, thiab kub. Nyob rau hauv qhov kev tshwm sim ntawm ib qho teeb meem hauv hluav taws xob, nws sai sai pom qhov tshwm sim siab nce thiab ua kom pom lub tswb ceeb toom ntawm lub txee sab nrauv. Qhov kev qhia tam sim no hauv zos tso cai rau kev txheeb xyuas qhov yuam kev sai thiab qhov chaw nyob. IFD system muab kev ceeb toom tseem ceeb thaum ntxov, ua kom muaj kev txiav txim siab txog kev saib xyuas, pab tiv thaiv kev puas tsuaj loj, txo lub sijhawm hluav taws xob tsawg, thiab txuas ntxiv tag nrho lub neej kev pab cuam ntawm lub transformer.

2.3 Tsis yog -PCB daim ntawv lo

Daim ntawv "Tsis yog-PCB" daim ntawv lo rau lub ncoo no -mounted transformer ua haujlwm tseem ceeb ntawm kev nyab xeeb thiab kev tshaj tawm ib puag ncig. Nws tau lees paub meej tias lub tshuab hluav taws xob dielectric insulating kua tsis muaj Polychlorinated Biphenyls (PCBs), tshuaj lom neeg ib zaug siv hauv cov khoom siv hluav taws xob qub. Daim ntawv lo no muab kev pom zoo tam sim ntawd rau cov neeg ua haujlwm siv hluav taws xob, cov neeg teb thawj zaug, thiab cov tswj hwm ib puag ncig uas lub tuam tsev ua raws li cov kev cai niaj hnub kev noj qab haus huv thiab kev nyab xeeb (xws li EPA cov lus qhia thiab IEEE tus qauv C57.12.29). Nws qhia txog qhov chaw ua haujlwm muaj kev nyab xeeb dua, yooj yim tuav thiab pov tseg cov txheej txheem, thiab cov chaw tsim khoom cog lus rau kev saib xyuas ib puag ncig thiab tsim kom ruaj khov.

2.4 Bushing zoo

Lub 200A 35kV chav kawm bushing zoo tsim los rau txiav cov thawj winding leads nyob rau hauv cov roj-cov units. Sab nraud mounted ntawm lub tank phab ntsa ntawm stainless hlau los yog zinc dichromate-plated 3- qhov clamps, nws haum 65 hli qhov thiab siv cov roj hmab gasket kom ruaj ntseg, ya raws - tiv taus sealing. Crafted los ntawm high{11}}polymer zoo nrog kub stability thiab tsis tshua muaj noo noo nqus, nws nta knurled tooj liab studs (kos los yog tshem tau) rau txhim khu kev qha conductivity, txhawb 200A tas mus li tam sim no thiab luv luv- lub sij hawm withstand peev xwm (10,000A / 0.17s los yog 3,500A / 3s). Nrog rau qhov ntsuas hluav taws xob mus txog 36.6kV theem- rau-theem thiab 150kV BIL, nws dhau los ua cov kev sim ntau lawm kom ntseeg tau tias ruaj khov, ua haujlwm zoo ib yam hauv qhov hnyav sab nraum zoov.

2.5 Lub luj tshib Arrester

Lub luj tshib ntes ua ke nrog cov hlau oxide varistor (MOV) module rau hauv peroxide - kho insulating thiab semi- ua cov vaj tse roj hmab, ua tau raws li IEEE 386 cov qauv rau kev sib hloov nrog cov khoom lag luam sib xws. Nruab nrog # 4AWG saj zawg zog tooj liab stranded woven hauv av txhuas thiab ib tug weatherproof stainless hlau cap, nws muab kev ruaj ntseg overvoltage tiv thaiv los ntawm disverting surge tam sim no rau hauv av, tiv thaiv pad mounted transformers, nkag mus, thiab underground tis systems thaum txuas lub neej cable. Featuring precision-moulded semiconducting shielding rau corona- kev ua haujlwm pub dawb, tus neeg ntes tau raug kuaj nruj (xws li kev tso tawm ib nrab, siab- tam sim no tawm, thiab thermal stability checks) thiab muaj nyob rau hauv ntau qhov kev ntsuas hluav taws xob kom haum rau cov kev xav tau sib txawv, ua kom muaj kev ruaj ntseg, kev tiv thaiv sab nraum zoov nyob rau hauv ib puag ncig harsh

03 Kev Xeem

DC winding kuj ntsuas (Kev Ntsuas Kev Ntsuas) rau lub ncoo mounted transformer ua rau tus nqi ntawm 4.45 ohms, ib qho kev ntsuam xyuas tseem ceeb los ntsuas qhov ncaj ncees ntawm transformer windings thiab kev ntseeg siab ntawm kev sib txuas hauv hluav taws xob. Qhov kev nyeem ntawv meej no tau lees paub qhov zoo ntawm tus neeg xyuas pib zoo, ruaj ntseg kev sib koom ua ke, thiab kev faib tawm tam sim no thoob plaws lub windings, txo qhov kev poob qis thaum ua haujlwm. Kev poob qis hauv qhov kev ua haujlwm zoo tshaj plaws, qhov ntsuas 4.45 ohm ua kom lub tshuab hloov hluav taws xob ua haujlwm ruaj khov, kev xa hluav taws xob zoo, thiab lub sijhawm ntev - kev cia siab rau hauv nroog faib kev siv hauv nroog.
