Cov kev tsis sib xws ntawm prefabricated transformer feem ntau cuam tshuam nws lub peev xwm, qib voltage, thiab kev ua haujlwm muaj peev xwm, nrog lub peev xwm thiab qhov hluav taws xob yog qhov tseem ceeb tshaj plaws. Peev xwm feem ntau qhia nyob rau hauv kVA, nrog rau cov specifications xws li 200kVA, 400kVA, thiab 630kVA, siv los txiav txim lub load nws yuav lis. Cov theem hluav taws xob tau muab faib ua siab -voltage thiab qis-voltage sab, xws li 10kV/0.4kV, uas yog qhov sib xyaw ua ke sib faib ntau tshaj plaws. Cov kev ntsuas no ncaj qha txiav txim siab qhov siv tau ntawm prefabricated transformer.
Luv-circuit impedance, poob, thiab kev ua tau zoo kuj yog cov cim tseem ceeb. luv-circuit impedance feem ntau nyob ib ncig ntawm 4% mus rau 6%, cuam tshuam qhov loj ntawm luv luv-circuit tam sim no thiab system stability. Tsis yog-load poob feem ntau cuam tshuam txog kev ua haujlwm tseem ceeb, thaum lub sij hawm thauj khoom poob yog cuam tshuam nrog cov winding conductors. Qhov qis dua ob qhov tseem ceeb no, qhov zoo dua ntawm kev lag luam ntawm cov khoom siv ua haujlwm. Kev ua tau zoo feem ntau yog siab, tab sis nyob rau hauv kev ua haujlwm ntev -, cov kev poob no cuam tshuam ncaj qha rau cov nqi hluav taws xob, yog li lawv tau txiav txim siab ua tib zoo thaum xaiv.
Cov chav kawm rwb thaiv tsev, chav tiv thaiv, thiab cov txheej txheem cua txias kuj tseem yog cov cim qhia tseem ceeb ntawm prefabricated transformers. Cov chav kawm rwb thaiv tsev txiav txim siab qhov kub thiab txias ua haujlwm ntawm cov khoom siv, thaum tiv thaiv chav kawm xws li IP54 thiab IP65 cuam tshuam rau sab nraum zoov plua plav thiab dej tsis kam. Cov kev ua kom txias muaj xws li roj immersion ntuj txias, yuam cua txias, thiab qhuav cua txias. Cov kev txwv no ua ke txiav txim siab txog kev ntseeg siab thiab kev pabcuam lub neej ntawm transformer substation nyob rau hauv ib puag ncig sib txawv.
