Hloov tooj liab raws nicrAlloy 180DEGREED chav kawm insulated enameled copper xov hlau

1.Material General Kev Piav Qhia

1)

Tus manganinyog ib qho alloy ntawm feem ntau 84% tooj liab, 12% mchankas, thiab 4% npib tsib xee.

Maneganin hlau thiab ntawv ci tau siv rau hauv kev tsim cov resistors, tshwj xeeb ammeter shunt, vim hais tias ntawm nws xoom coeffentance thiab ntev lub sij hawm ruaj khov. Muaj ntau cov maneginin resistors tau ua tus qauv kev cai lij choj rau OHM hauv Tebchaws Meskas yog siv rau kev hloov pauv ntawm cov ntsiab lus uas xav tau kev sib txuas hluav taws xob uas xav tau kev sib txuas hluav taws xob uas xav tau kev sib txuas hluav taws xob uas xav tau kev sib txuas hluav taws xob uas xav tau kev sib txuas hluav taws xob uas xav tau cov hluav taws xob uas xav tau.

MANAGIN kuj tau siv rau hauv gauges rau kev tshawb fawb ntawm cov kev tawm tsam siab (xws li cov khoom tawg) vim tias nws muaj qis zog siab rhiab heev tab sis siab hydrostatic siab rhiab.

2)

Constantanyog tooj liab-nickel alloy tseem hu uaEjeka, Mus ua ntej, thiabLub nkoj thauj khoomCov. Nws feem ntau muaj 55% tooj liab thiab 45% npib tsib xee. Nws lub ntsiab tseem ceeb yog nws txoj kev tiv thaiv tsis yooj yim, uas yog tas li ntau qhov kub. Lwm cov alloys nrog cov coeffici zoo sib xws yog paub, xws li manganin (cu₈₆Mn₁₂Ni₂).

Rau kev ntsuas ntawm cov leeg loj heev, 5% (50 000 microstrian) lossis siab dua, annealed constantan (p alloy) yog cov khoom siv sib tw ib txwm xaiv. Constantan hauv daim foos no yog coo heev; Thiab, hauv kev ntsuas ntsuas ntev ntawm 0.125 nti (3.2 hli) thiab ntev dua, tuaj yeem ua rau muaj> 20%. Nws yuav tsum tau yug los hauv siab, txawm li cas los xij, uas nyob rau hauv siab cyclics pulouss p alloy yuav muab qee qhov kev voj voog ua mus ncig, thiab ua rau muaj kev hloov pauv tsawg dua hauv lub ntsuas cua. Vim tias cov xeeb ceem no, thiab nyiam ua ntej yug menyuam ua tsis tiav, P Alloy tsis tau pom zoo rau kev siv lub voj voog. P Alloy yog muaj nrog tus lej STC ntawm 08 thiab 40 rau kev siv hlau thiab yas, ntsig txog.

2. Enamelled Hlau Taw Qhia Thiab Kev Siv

Txawm hais tias tau piav qhia raws li "enameled", enameled xaim tsis yog, qhov tseeb, coated nrog ib txheej ntawm cov kua ntoo uas muaj zog ua los ntawm fuse iav hmoov. Cov hlau nplaum niaj hnub siv ib qho mus rau plaub txheej (nyob rau hauv plaub daim duab raj hlau) ntawm ob qho sib txawv, los muab cov txheej sib txawv, txuas ntxiv accessulating txheej. Hlau nplaum hlau insulating cov yeeb yaj kiab siv (nyob rau hauv kev nce qib kub) polyestane, polyester-polyimide-polyimoside (lossis kev ua kom zoo-imide), thiab polyimide. Polyimide Insulated hlauet hlau muaj peev xwm ua haujlwm ntawm li 250 ° C. Lub rwb thaiv tsev ntawm thicker square lossis duab plaub yaus magnet yog feem ntau nqus cov vuas thiab ua tiav cov kua roj vuas thiab ua tiav kev sib zog ntawm winding.

Kev txhawb nqa tus kheej yog qhov txhab nrog hlau coated nrog tsawg kawg ob txheej, lub thermoplastic uas thermopicastic uas daim ntawv sib dhos ua ke thaum rhuab.

Lwm hom rwb thaiv tsev xws li fiberglass xov nrog varnish, aramid daim ntawv, kraft ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester daim ntawv, thiab polyester ntawv siv thoob plaws ntiaj teb rau ntau yam kev siv xws li transformers thiab reactors. Nyob rau hauv lub schio sector, ib xaim ntawm cov insulators, xws li cov rwb (qee zaum permeated) Cov khoom siv rwb thaiv tsev uas muaj cov paj rwb, ntawv,, tab sis cov no tsuas yog pab tau rau cov ntawv thov tsawg (txog li 105 ° C).

Txhawm rau kom yooj yim ntawm kev tsim khoom, qee qhov tsawg-theem-qib hlau nplaum muaj rwb thaiv tsev uas tuaj yeem tshem tawm los ntawm cov cua sov. Qhov no txhais tau tias kev sib txuas hluav taws xob ntawm qhov xaus tuaj yeem ua tau tsis muaj kev tawm hws tawm lub rwb thaiv tsev ua ntej.
