Hwj chim Functionality thiab yooj yim Expandability
Ib lub ntsuas hluav taws xob hluav taws xob ib leeg ua haujlwm sib npaug rau ntau qhov induction- hom ntsuas hluav taws xob. Piv txwv li, ib qho khoom siv hluav taws xob uas muaj ntau yam -function meter ua haujlwm tib lub hom phiaj xws li ob lub zog rau pem hauv ntej, ob lub zog hluav taws xob rau pem hauv ntej, ob qhov kev thov siab tshaj plaws, thiab ib qhov hluav taws xob- poob timer. Tsis tas li ntawd, nws ua rau muaj peev xwm ua tau siab heev-xws li lub sijhawm- ntawm- siv (TOU) ntsuas thiab tsis siv neeg nyeem cov ntaub ntawv- uas xya cais meters no ua tsis tau. Raws li qhov tshwm sim, qhov txo qis ntawm cov ntsuas lub cev muaj txiaj ntsig zoo txo qis qis qis hauv lub voj voog thib ob, yog li txhim kho qhov kev ntseeg tau thiab qhov tseeb ntawm tag nrho cov ntsuas ntsuas.
High thiab Stable Accuracy Class
Cov chav kawm raug ntawm induction- hom ntsuas hluav taws xob feem ntau nyob ntawm Chav Kawm 0.5 txog Chav Kawm 3.0; Tsis tas li ntawd, vim kev siv tshuab, lawv cov npoo tsis zoo yog qhov yooj yim rau ya raws sijhawm. Hauv qhov sib piv, cov ntsuas hluav taws xob hluav taws xob tuaj yeem ua tiav cov chav kawm raug siab dua- feem ntau yog txij li Chav Kawm 0.2 mus rau Chav Kawm 1.0-los ntawm kev siv yooj yim ntawm ntau cov txheej txheem them nyiaj, thaum tseem qhia txog kev ua yuam kev zoo dua.
Tsawg pib tam sim no thiab tiaj tus yuam kev nkhaus
Induction- hom ntsuas hluav taws xob xav tau qhov hnyav tsawg kawg 0.3% ntawm cov ntsuas tam sim no (Ib) los pib ua haujlwm thiab pib ntsuas; lawv qhov kev ua yuam kev nkhaus zoo li hloov pauv ntau, nrog cov kev ua yuam kev tau dhau los ua tshwj xeeb tshaj tawm nyob rau hauv qis -load tej yam kev mob. Cov hluav taws xob hluav taws xob ntsuas hluav taws xob, txawm li cas los xij, yog qhov rhiab heev; Lawv tuaj yeem pib ua haujlwm thiab ntsuas ntawm qhov hnyav li 0.1% ntawm Ib. Tsis tas li ntawd, lawv muaj qhov ua yuam kev zoo heev nkhaus, tswj qhov kev ua yuam kev uas tseem nyob zoo li linear thoob plaws tag nrho cov khoom thauj.
Wide Frequency Response Range
Cov lus teb ntau zaus ntawm induction- hom ntsuas hluav taws xob feem ntau yog txwv rau 45-55 Hz, whereas ntawm cov khoom siv hluav taws xob ntau-function meters spans ntau ntau ntawm 40-1000 Hz.
Yam tsawg kawg nkaus Susceptibility rau Sab Nraud Sib Nqus Fields
Induction- hom ntsuas hluav taws xob ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction; Yog li ntawd, lawv cov metering kev ua tau zoo heev raug cuam tshuam los ntawm sab nraud magnetic teb. Lub zog hluav taws xob ntsuas hluav taws xob, hloov pauv, vam khom feem ntau ntawm cov lej digital rau lawv cov lej; Yog li ntawd, lawv cov metering kev ua tau zoo tseem tsis cuam tshuam los ntawm sab nraud magnetic teb.
Yooj yim ntawm kev teeb tsa thiab kev ua haujlwm
Induction- hom hluav taws xob ntsuas yuav raug rau cov kev cai nruj heev; tshwj xeeb, ib qho kev sib txawv tseem ceeb los ntawm kev txhim kho kab rov tav zoo kawg nkaus - lossis pom qhov qaij - yuav ua rau muaj qhov ntsuas tsis raug. Cov hluav taws xob hluav taws xob ntsuas hluav taws xob, txawm li cas los xij, siv lub tshuab ntsuas hluav taws xob nkaus xwb tsis muaj cov khoom siv sib hloov; lawv thiaj li tiv thaiv tau cov teeb meem uas tau hais tseg no. Tsis tas li ntawd, lawv qhov loj me thiab lub teeb yuag tsim ua rau lawv yooj yim heev rau nruab thiab ua haujlwm.
Muaj peev xwm overload
Induction- hom ntsuas hluav taws xob ua haujlwm raws li kev sib cuam tshuam ntawm cov coils; los xyuas kom meej qhov ntsuas qhov tseeb, lawv feem ntau txwv rau qhov muaj peev xwm dhau mus txog plaub npaug ntawm lawv cov nqi ntsuas. Hauv qhov sib piv, cov khoom siv hluav taws xob ntau- cov ntsuas ntsuas muaj peev xwm tiv taus cov khoom siv ntau dhau los ntawm rau txog rau kaum npaug ntawm lawv cov peev txheej ntsuas.
Txhim kho Kev Tiv Thaiv -Kev Muaj Peev Xwm Tub Sab
Kev tub sab hluav taws xob ua ib qho kev muaj tiag uas tsis muaj nyob hauv nroog thiab nyob deb nroog siv hluav taws xob thoob plaws kuv lub tebchaws; induction- hom ntsuas hluav taws xob, txawm li cas los xij, muaj peev xwm tsis muaj zog los tiv thaiv cov tub sab nyiag. Cov tiam tshiab ntawm cov ntsuas hluav taws xob hluav taws xob hais txog qhov teeb meem no los ntawm kev siv cov qauv tsim qauv tshwj xeeb tshwj xeeb los tiv thaiv ntau hom kev nyiag hluav taws xob. Piv txwv li, ADE7755 nti siv ob qhov sib cais tam sim no transformers los ntawm nws tus kheej ntsuas qhov tam sim no ntws los ntawm ob theem kab thiab kab nruab nrab; nws mam li pib nws lub zog ntsuas ntsuas ntawm qhov twg ntawm ob qhov kev nyeem tam sim no siab dua. Cov txheej txheem no zoo tiv thaiv txoj kev tub sab uas cuam tshuam nrog luv luv -circuiting lossis bypassing tam sim no - nqa cov xov hlau.
