Cov khoom siv raw rau cov khoom siv cua sov nrog indirect resistors

Indirect resistors feem ntau yog siv los ua raw khoom rau cov khoom siv cua sov, nrog kev ua haujlwm siab, tsis tshua muaj kub coefficient ntawm resistors, me deformation ntawm qhov kub thiab txias, thiab tsis tshua muaj kev laus. Cov ntaub ntawv uas tsis yog xim hlau muaj xws li hlau aluminium alloy profiles, nickel chromium thiab lwm yam khoom siv hlau sib xyaw, cov khoom siv carbon carbon, thiab molybdenum disilicide. Kev khiav hauj lwm kub ntawm cov khoom siv hlau kub yuav tsum ncav cuag 1000-1500 degree nyob ntawm seb hom khoom siv raw; Kev khiav hauj lwm kub ntawm cov khoom tsis yog xim hlau cov khoom kub nce mus txog 1500-1700 degree . Hom tom kawg yog ib qho yooj yim rau nruab thiab tuaj yeem hloov tau los ntawm lub tshuab hluav taws xob, tab sis nws yuav tsum yog cov khoom siv hluav taws xob hloov pauv thaum lub sijhawm ua haujlwm. Nws cov kev pab cuam lub neej yog luv dua li ntawm aluminium alloy cua sov Cheebtsam. Nws feem ntau yog siv nyob rau hauv high-kub hluav taws xob rauv, qhov chaw uas qhov kub thiab txias tshaj qhov tso cai rau kev khiav hauj lwm kub ntawm cov hlau puas cua sov Cheebtsam, thiab ib co tshwj xeeb qhov chaw. Cov nyhuv thermoelectric generated los ntawm induced electromotive quab yuam (vortex) ntawm ib tug hluav taws xob conductor nyob rau hauv ib tug alternating magnetic teb ua rau tus neeg xyuas pib kom sov nws tus kheej. Raws li cov txheej txheem cua sov sib txawv, qhov zaus ntawm AC siv rau kev sib nqus induction cua sov muaj xws li tam sim no ncaj qha (50-60 Hz), siab zaus (60-10000 Hz), thiab siab zaus (dhau 10000 Hz). DC switching fais fab mov yog AC fais fab tso tawm nyob rau hauv kev lag luam ntau lawm, thiab feem ntau ntawm DC nyob rau hauv lub ntiaj teb no yog 50 hertz. Lub zog ua haujlwm ntawm DC hloov hluav taws xob siv rau kev sib nqus induction cua sov siv rau cov khoom siv sib nqus induction yuav tsum tau kho. Raws li qhov tso zis hluav taws xob loj ntawm cov cuab yeej siv cua sov thiab qhov ntim loj ntawm lub zog hluav taws xob network, DC high-voltage fais fab mov (6-10KV) tuaj yeem siv los muab lub zog rau lub tshuab hloov pauv; Cov cuab yeej siv tshuab cua sov tuaj yeem txuas tau tam sim ntawd rau 380V hauv qab hluav taws xob hluav taws xob hluav taws xob.
