Pad-mount Transformer
A padmount transformer, tseem hu ua underground transformer los yog substation transformer, yog ib hom hluav taws xob transformer uas yog tsim los rau nruab rau hauv av nto, feem ntau nyob rau hauv lub ncoo los yog vault. Nws yog feem ntau siv los txo qis hluav taws xob hluav taws xob los ntawm cov kab xa khoom mus rau qhov qis qis uas tsim nyog rau kev siv hauv zos hauv thaj chaw, kev lag luam, lossis chaw lag luam.
Ntawm no yog ib lub ntsiab lus tseem ceeb ntawm yuav ua li cas apadmount transformerua haujlwm:
- Npog
A padmount transformeryog nyob rau hauv ib tug ruaj khov, weatherproof enclosure ua los ntawm cov ntaub ntawv xws li steel los yog pob zeb. Qhov no enclosure tiv thaiv lub transformer los ntawm lwm yam xws li ya raws, plua plav, thiab lub cev puas tsuaj.
- Thawj thiab Secondary Windings
Lub transformer muaj cov thawj thiab theem nrab windings. Thawj winding yog txuas nrog high-voltage tis kab, thaum lub thib ob winding muab cov zis voltage qis.
- Core thiab Coil
Nyob rau hauv lub enclosure, muaj ib tug tseem ceeb ua los ntawm laminated steel. Lub hauv paus thiab theem nrab windings raug mob nyob ib ncig ntawm lub hauv paus no. Cov tub ntxhais lub hom phiaj yog los tsim ib qho kev sib nqus hluav taws xob uas hloov hluav taws xob hluav taws xob los ntawm thawj zaug mus rau theem nrab winding.
- Rwb thaiv tsev
Cov windings yog insulated los tiv thaiv hluav taws xob to thiab ua kom muaj kev nyab xeeb. Cov ntaub ntawv rwb thaiv tsev xws li ntawv, roj-impregnated ntawv, lossis cov khoom siv hluavtaws yog siv los cais cov windings thiab muab hluav taws xob rwb thaiv tsev.
- Txias System
Padmount transformersfeem ntau siv roj ua ib lub coolant thiab insulator. Lub transformer lub hauv paus thiab windings yog immersed nyob rau hauv ib tug tshwj xeeb formulated transformer roj uas pab dissipate tshav kub generated thaum lub sij hawm ua hauj lwm. Cov roj kuj tseem muab cov rwb thaiv tsev ntxiv thiab tiv thaiv cov windings los ntawm ya raws thiab cov kab mob.
- Bushings thiab Terminals
Bushings yog cov khoom siv insulated uas muab kev sib txuas hluav taws xob ntawm cov transformer windings thiab lwm tus neeg xyuas pib. Lawv tso cai rau kev nyab xeeb thiab txhim khu kev qha kev sib txuas ntawm high-voltage thiab low-voltage cables. Terminals yog siv los txuas lub transformer rau cov kab xa khoom thiab cov khoom thauj.
- Kev Tiv Thaiv thiab Saib Xyuas
Padmount transformerstau nruab nrog ntau yam khoom siv tiv thaiv thiab kev saib xyuas. Cov no muaj xws li fuses, Circuit Court breakers, kub sensors, siab nyem li, thiab roj qib ntsuas. Cov yam ntxwv no pab ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm lub tshuab hluav taws xob los ntawm kev kuaj xyuas thiab teb rau cov xwm txheej txawv txav xws li overloads, luv circuits, lossis overheating.
Hauv cov ntsiab lus, apadmount transformernqis qis hluav taws xob high-voltage los ntawm cov kab xa khoom mus rau qhov qis dua qhov tsim nyog rau kev siv hauv zos. Nws muaj cov thawj thiab theem nrab windings, ib tug tub ntxhais, rwb thaiv tsev, ib tug txias system, bushings, terminals, thiab cov khoom tiv thaiv. Lub tshuab hluav taws xob ua haujlwm yog nyob ntawm cov qauv siv hluav taws xob thiab cov txheej txheem rwb thaiv tsev kom hloov hluav taws xob hluav taws xob zoo thiab nyab xeeb.
