112.5 kVA Pad Mounted Transformer-34.5/0.208 kV|USA 2024

01 General

1.1 Project Background

112.5 kVA peb theem ncoo mounted transformer tau xa mus rau Tuam Tshoj hauv xyoo 2024. Lub zog ntsuas ntawm lub transformer yog 112.5 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 34.5GrdY / 19.92kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.12 / 0.208kV, lawv tsim ib pawg vector ntawm YNyn0.

Peb -Phase Pad-Mounted Transformer yog ib qho khoom siv hluav taws xob uas siv dav hauv cov tshuab xa tawm, feem ntau muab lub zog rau thaj chaw nyob, thaj chaw lag luam, chaw ua haujlwm, thiab lwm qhov chaw. Peb -theem ncoo-mounted transformer tau txais hluav taws xob hluav taws xob los ntawm nws qhov siab-voltage sab thiab nqis qis qis rau qhov hluav taws xob qis mus rau qhov tsis tshua muaj hluav taws xob rau cov khoom siv hluav taws xob. Qhov siab-voltage sab feem ntau yog txuas nrog lub nplhaib network lossis lub davhlau ya nyob twg pub, thaum qhov qis-voltage sab xa hluav taws xob rau lub load. Internal load keyboards thiab fuses muab kev tiv thaiv kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv. Fuses thiab cable terminals tau muab tso ua ke rau hauv tib lub cable compartment, nrog optimized spatial tsim kom ntseeg tau yooj yim rau kev khiav hauj lwm thiab txij nkawm. Cov qauv kev sib txuas ntawm lub fuse thiab cable davhlau ya nyob twg yog tsim los, siv cov khoom siv hluav taws xob siab (piv txwv li, nyiaj-plated tooj liab) thiab cov cuab yeej sib txuas lus precision kom txo tau qhov kev sib cuag thiab xyuas kom muaj hluav taws xob zoo heev.

02 Kev tsim khoom

2.1 Core

Cov tub ntxhais muaj peb ceg ntsug (kem), Txhua ceg nqa ob txheej windings (high-voltage winding thiab low-voltage winding), sib xws rau peb theem tam sim no (theem A, B, thiab C). Peb ceg yog txuas nrog kab rov tav yokes, tsim ib txoj kev sib nqus kaw. Qhov peb -legged qauv ua kom muaj kev sib nqus sib nqus, txo qhov kev pheej hmoo ntawm kev sib nqus sib nqus. Qhov peb -legged qauv ua kom muaj kev sib nqus sib nqus sib nqus, txo qhov kev pheej hmoo ntawm kev sib nqus sib nqus.

2.2 Cua txias

High-voltage wire winding tuaj yeem kho tus lej hloov thiab qhov sib nrug los ntawm cov txheej txheem tsim, ua tau raws li qhov yuav tsum tau muaj ntawm ntau qib high voltage thaum txhim kho kev ua haujlwm rwb thaiv tsev thiab kev nyab xeeb. Los ntawm kev siv cov txheej txheem tsim nyog thiab segmenting cov tswv yim, xaim winding tuaj yeem txhim kho cov hluav taws xob xa hluav taws xob zoo, tiv thaiv cov hluav taws xob hauv zos ntau dhau uas yuav ua rau muaj kev cuam tshuam tsis zoo. Hauv cov xaim winding, cov cua txias tuaj yeem muab tso rau hauv cov qauv los txhim kho cov cua sov, ua kom lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm siab -voltage windings. Lub zog txhua yam ntawm cov hlau winding nyob ntawm cov khoom siv thiab cov txheej txheem winding, tso cai rau tsim kom muaj zog tensile thiab deformation tsis kam raws li xav tau.

2.3 Tank

Lub thawv tsim tag nrho txiav txim siab txog qhov yuav tsum tau muaj dej tsis zoo, kev nyab xeeb thiab kev ua haujlwm yooj yim. Lub siab thiab qis voltage chamber tiv thaiv qhov rooj yog mechanically interlocked, thiab tsuas yog thaum lub qhov rooj tiv thaiv tsis tshua muaj siab qhib, lub qhov rooj tiv thaiv siab tuaj yeem qhib kom ntseeg tau tias muaj kev nyab xeeb ntawm kev ua haujlwm thiab cov neeg ua haujlwm tu. Lub thawv yog ua los ntawm cov khoom zoo carbon steel phaj, uas yog ua los ntawm precision machining ntawm txhua tus txheej txheem. Tom qab kev kho mob nruj ntawm sab hauv thiab sab nrauv ntawm lub thawv, cov txheej txheem electrostatic hmoov txau yog siv rau peb zaug kev kho hmoov, thiab cov xim txheej muaj zog, hnav- tiv taus thiab tsis muaj dej, thiab tiv taus hluav taws xob ultraviolet.
