Resistance welding transformers yog cov khoom siv vuam siv nrog cov khoom siv hluav taws xob AC nyob ntawm 50-60Hz thiab qis dua 1000V. Lawv muaj kev ua haujlwm siab vuam, ceev ceev, muaj zog welds, thiab txo cov nqi vuam. Feem ntau siv nyob rau hauv cov chaw vuam tshuab, seam vuam tshuab, thiab lub taub qab vuam tshuab, lawv yog tshwj xeeb tshaj yog haum rau cov ntaub ntawv uas muaj thermal conductivity los yog tsis zoo weldability, xws li txhuas alloys thiab txhuas. Hauv vuam galvanized nplooj ntawv thiab ntau- txheej daim hlau, lawv muaj qhov zoo dua qub dua li lub zog zaus vuam tshuab. Cov tub ntxhais yog ua los ntawm txias- dov, siab- zoo lis-taw qhia txog silicon steel nplooj ntawv, nrog 1-2 lem hauv winding. Lub rwb thaiv tsev kub tiv thaiv chav kawm yog F, qhov impedance qis dua 10⁻³Ω, thiab nws txhawb 4-12 qib ntawm kev tswj tam sim no.
Qhov thib ob sab kev khiav hauj lwm tam sim no ntau yam ntawm no transformer yog 2000 ~ 40000A. Nws muaj nyob rau hauv ob hom voltage: tsau (tsawg dua los yog sib npaug rau 10V) thiab tshem tawm (≈24V). Lub peev xwm tshaj 50kVA, thiab kev tswj fais fab tau ua tiav los ntawm kev hloov cov lej ntawm cov kev hloov pauv hauv thawj winding. Cov tub ntxhais siv cov tub ntxhais kawm - hom qauv tsim, ua ke nrog ntuj lossis dej txias tshuab, kom ua tau raws li qhov xav tau ntawm lub zog sib txawv. Nws ua haujlwm nyob rau hauv lub zog sib txuas thiab tsis muaj -cov xwm txheej thauj khoom (tshwj tsis yog lub pob nyem vuam). Ib puag ncig yuav tsum muaj xws li qhov siab tshaj qhov siab tsis tshaj 2000 meters, qhov kub thiab txias tsawg dua lossis sib npaug li 40 degree, av noo tsawg dua lossis sib npaug li 90%, thiab tsis muaj kev vibration hnyav thiab corrosive gases.
