I. Cov ntsiab lus txhais thiab RESORANCE ALSE Ranges
Tsawg - Tsis kam Cable Txhaum (qis- tsis kam):
Txhais:Lub rwb thaiv tsev tsis kam ntawm qhov txhaum cai poob mus rau theem qis heev, lossis txawm tias dhau los ua tus thawj coj luv luv nrog tus neeg xyuas pib. Raws li DC cov hluav taws xob ntau, hluav taws xob tsis tuaj yeem tsim tsa ntawm qhov txhaum kev txhaum; Nws tawg cia tam sim ntawd, tsim qhov tsawg-} tsis kam.
Kuj:Feem ntau yog hais txog kev tiv thaiv mus rau hauv av (lossis nruab nrab ntawm theem) tsawg dua100-200 Ohms(Ib qho kev lag luam muaj txiaj ntsig, tsis yog tus qauv meej; qee zaum tus ciam yog teeb tsa ntawm 10 zaug ntawm cable tus yam ntxwv tsis zoo).
High - Tsis kam Cable Txhaum (Siab- Tsis kam):
Txhais:Cov rwb thaiv tsev tsis kam ntawm qhov chaw ua txhaum tau poob qis tab sis tseem muaj siab. Thaum DC cov hluav taws xob siab yog thov, qhov kev txhaum taw tes tuaj yeem tiv thaiv qee qhov voltage kom txog thaum lub voltage sawv siab txaus rau kev ua yuam kev.
Kuj:Feem ntau yog hais txog qhov tsis kam mus rau hauv av (lossis nruab nrab ntawm theem) ntau dua200-300 ohms, thiab muaj peev xwm txawm mus txog Megaohm qib. Siab - Tsis kam ua txhaum ntau dua, suav rau txog 80-90% ntawm tag nrho cov cable yuam kev.
Ii. Sib piv cov lus ntawm qhov sib txawv
| Qhov loj tshaj plaws | Tsawg - Tsis kam Cable Txhaum | High - Tsis kam Cable Txhaum |
|---|---|---|
| Tub Ntxhais Txhais | Tsawg heev ua txhaum lub ntsiab lus tiv taus,DC Kev Generator siab tsis tuaj yeem tsim tau | Siab txhaum kev tiv thaiv,DC lub siab voltage tuaj yeem tsim tau thiab thaum kawg ua rau rhuav tshem |
| Kuj muaj nqi | Qi(Feem ntau <100-200 ω) | Siab(Feem ntau> 200-300 ω, tuaj yeem nce txog Mω Qib) |
