Iyini Ikhebula Lezinsimbi Ezivikelwe Futhi Kungani Ukuvikela Kubalulekile?
- Impendulo Eqondile: Isendlalelo Esivikelayo Sezimpawu Ezibucayi
Abantu bahlala bebuza:"Iyini ikhebula lezinsimbi ezivikelwe?"
Impendulo elula:Ikhebula lezinsimbi ezivikelwe yikhebula elinesendlalelo esengeziwe sokuhambisa umoya - ngokuvamile i-aluminium foil, i-copper braid, noma kokubili - eligoqwe ngama-insulated conductors. Lesi sivikelo sisebenza njengesivikelo, sivikela izimpawu zokulinganisa ezibucayi ngaphakathi ekuphazamisekeni kwe-electromagnetic yangaphandle (EMI) kanye nokuphazamiseka kwe-radio-frequency (RFI).
Kungani Ukuvikela Kubalulekile:
| Inkinga | Ngaphandle kokuvikela | Ngokuvikela |
| Ama-motor aseduze nama-VFD | I-EMI ibangela umsindo ezintanjeni zesiginali → ukufundwa okungaguquki | Isivikelo sivimba i-EMI → isignali ehlanzekile nezinzile |
| Ama-radio transmitter (ama-walkie-talkie, imibhoshongo yeselula) | I-RFI ihlangana nekhebula → izimpawu zamanga | Isivikelo sibonakalisa/simunca i-RFI → idatha ethembekile |
| Izintambo ezisebenza ngokulingana nezintambo zikagesi | I-voltage ebangelwayo ibangela amaphutha okulinganisa | Isivikelo sidlulisela umsindo obangelwayo phansi |
| Imishini yokushisela eseduze | Ukuphazamiseka okukhulu konakalisa ukuxhumana kwedijithali | Isivikelo sivikela izimpawu zokulawula ezibalulekile |
| Umsindo kagesi obanzi wesitshalo | Isilinganiso sesiginali kuya kumsindo siyawohloka → ukunemba okuncishisiwe | Isivikelo sigcina ubuqotho besiginali |
Iphuzu Eliyinhloko:Ezindaweni zezimboni, izintambo zezinsimbi ezingavikelwe zingase zihlaselwe umsindo ongenza ama-loop angu-4-20mA anganembile, abangele ukufundwa kwe-RTD kushintshe, futhi konakalisa ukuxhumana kwedijithali njenge-RS485 noma i-Modbus.
Ku-Dingzun Cable,sakha izintambo zezinsimbi ezivikelwe nge-foil, i-braid, kanye nezinketho zokuvikela ezihlanganisiwe — ezenzelwe indawo yakho ethile ye-EMI kanye nezidingo zokuzwela kwesignali.
- Indlela Ukuvikela Okusebenza Ngayo: Isayensi Yokuvikelwa Kwe-EMI
Ukuvikela kusebenza ngokuvimba amandla kagesi bese kuqondiswa phansi ngaphambi kokuba kufinyelele kubaqondisi besignali.
