Taw qhia
Ib theem ncej mounted transformersyog structurally yooj yim thiab compact loj. Lawv feem ntau ntsia tau rau hauv ib qho kev dai (ntawm ib leeg lossis ob tus ncej) ze rau cov ntsiab lus hluav taws xob thauj khoom, uas ua rau qis qis -voltage supply radius. Qhov no ua rau lawv tsim nyog rau kev faib khoom siv hluav taws xob, thiab lawv tuaj yeem ua haujlwm raws li ib theem units lossis peb chav ua ke rau peb theem ua haujlwm. Tam sim no, lawv tau siv dav hauv thaj chaw xws li Tebchaws Meskas, Canada, Mexico, Southeast Asia, thiab South America.

Polarity
Cov kev cai polarity sib txawv raws cheeb tsam. Raws li IEEE Std C57.12.20, ib theem transformers muaj ob qho tib si ntxiv thiab rho tawm polarity.
Cov qauv no qhia tau hais tias transformers muaj peev xwm tsawg dua los yog sib npaug rau 200kVA thiab high voltage Tsawg dua los yog sib npaug rau 8660V yuav tsum tau ua nrog additive polarity, thaum lwm tus yuav tsum muaj rho polarity.
Bushings
| Hom Bushing | Cov lej muaj peev xwm | Nqe lus piav qhia / Lus Cim |
| High Voltage (HV) | 1 (Ib leeg) | Ib tug bushing ntawm sab saum toj cover; lwm kawg grounded hauv tank. |
| 2 (ob npaug) | Ob lub bushings ntawm sab saum toj npog. | |
| Tsawg Voltage (LV) | 2, 3, or 4 ib | Feem ntau sab -mounted. Dual-voltage windings tuaj yeem txuas rau hauv kev sib txuas lossis txuas. |
Ua tiav Tus Kheej -Kev Tiv Thaiv (CSP)
Yog hais tias lub transformer muaj CSP, nws muaj xws li ntes (s) thiab fuse (s) nyob rau sab HV, thiab Circuit Court breaker (s) ntawm LV sab. Tus LV ntes yog xaiv tau. CSP koom ua ke ntau yam kev tiv thaiv, suav nrog kev tiv thaiv xob laim, kev qhia ntau dhau, LV Circuit Court breaker tripping, thiab luv luv -circuit fuse ua haujlwm - kom ua tiav kev tiv thaiv tsis siv neeg hloov pauv.
Qauv
Lub transformer tuaj yeem ua tau nrog cov tub ntxhais -hom lossis lub plhaub- hom qauv. Cov khoom siv tseem ceeb tuaj yeem yog amorphous alloy lossis silicon steel los xij, thiab ob hom siv lub qhov txhab -core tsim nrog qhib sib koom ua ke.
Core- hom: Ib qho tseem ceeb nrog ob lub coils. Cov tub ntxhais feem ntau muaj sab saum toj - qhib kev sib koom ua ke, thiab qhov kev sib tw winding feem ntau ua raws li qis - kev teeb tsa siab.
Plhaub- hom: Ib lub kauj nrog ob lub cores. Cov tub ntxhais feem ntau nta ib sab - qhib kev sib koom ua ke, thiab qhov kev sib tw winding tej zaum yuav qis dua - siab- qis lossis qis - siab.
Roj Tank
Lub tank feem ntau yog ua los ntawm 2-3 hli txias-kuav los tiag steel phaj tsim rau hauv cov duab cylindrical. Lub hau tuaj yeem txuas nrog lub cev cylindrical los ntawm ib lub clamping band lossis los ntawm tus qauv nias-pin. Upper thiab qis lifting lugs yuav tsum tau welded mus rau lub cev raws li tus qauv yuav tsum tau. Qhov sib txawv me me ntawm huab cua yog tshwj tseg rau saum lub tank kom haum rau thermal expansion thiab contraction ntawm cov roj transformer. Raws li cov kev xav tau ntawm kev ua tau zoo, cov radiators yog haum, uas tuaj yeem yog corrugated fins lossis phaj hom radiators.
Xaus
Tus tsim ntawm ncej mounted transformers ib txwm ntaus ib qho sib npaug ntawm cov qauv tsim thiab cov kev cai. Txawm hais tias nws yog qhov kev xaiv ntawm cov tub ntxhais -hom thiab plhaub- hom, lossis qhov sib txawv ntawm qhov ntau thiab CSP kev teeb tsa, txhua yam thaum kawg ua haujlwm txhim khu kev qha hauv cov xwm txheej tshwj xeeb. VKE Transformer lub hom phiaj yog qhov tseeb los pab cov neeg siv khoom ua tiav qhov nyiaj tshuav no. Peb tuaj yeem pab koj los txhais cov kev xav tau ntawm qhov project kom meej, ua tau zoo transformer specifications - thiab xyuas kom meej tias cov khoom kawg ua tau raws li qhov xav tau.
