Yintoni iCable yeZixhobo eziKhuselekileyo kwaye Kutheni iCable ibalulekile?
- Impendulo Ethe Tye: Umaleko Okhuselayo Weempawu Ezinovakalelo
Abantu bahlala bebuza:"Yintoni intambo yezixhobo ezikhuselweyo?"
Impendulo elula:Intambo yezixhobo ezikhuselweyo yintambo enomaleko owongezelelweyo wokuhambisa umoya - ngesiqhelo ifoyile ye-aluminiyam, i-copper braid, okanye zombini - ezijikelezileyo kwii-insulated conductors. Le ngwebo isebenza njengomqobo, ikhusela imiqondiso yokulinganisa ebuthathaka ngaphakathi kwi-external electromagnetic interference (EMI) kunye ne-radio-frequency interference (RFI).
Kutheni Kubalulekile Ukukhusela:
| Ingxaki | Ngaphandle kokukhusela | Ngokukhusela |
| Iimoto ezikufutshane kunye neeVFD | I-EMI ibangela ingxolo kwiingcingo zesignali → ukufundwa okungaguquguqukiyo | Iibhloko zeShield EMI → isignali ecocekileyo nezinzileyo |
| Iitransmitter zerediyo (ii-walkie-talkies, ii-cell towers) | I-RFI idibana kwikhebula → imiqondiso yobuxoki | Isihlangu siyabonakalisa/siyafunxa i-RFI → idatha ethembekileyo |
| Iintambo ezihamba ngaxeshanye neentambo zombane | I-voltage ebangelwayo ibangela iimpazamo zokulinganisa | Isihlangu sijika ingxolo ebangelwayo iye emhlabeni |
| Izixhobo zokuwelda ezikufutshane | Ukuphazamiseka okukhulu konakalisa unxibelelwano lwedijithali | Isihlangu sikhusela imiqondiso ebalulekileyo yokulawula |
| Ingxolo ye-electromagnetic ebanzi kwizityalo | Umlinganiselo wesignali-kwingxolo uyawohloka → ukuchaneka okunciphileyo | Isihlangu sigcina ukuthembeka kwesiginali |
Eyona Nto Ibalulekileyo:Kwiindawo zoshishino, iintambo zezixhobo ezingagqunywanga zisengozini yengxolo enokwenza ii-loops ze-4-20mA zingachaneki, zibangele ukufundwa kwe-RTD kutshintshe, kwaye zonakalise unxibelelwano lwedijithali olufana ne-RS485 okanye i-Modbus.
