Itheyibhile 2. Iiparamitha zombane
Ubude obuninzi bekhebula le-sensor lichongwa ngokuchasana (max. 75 Ω) kunye nezinye iiparameters zombane (Co, Lo kunye neLo / Ro) yesiphaluka senzwa.
| Example: | Ukumisela ubude bobude bekhebula |
| Intambo yesixhobo eneempawu ezilandelayo isetyenziswa:
- Ukuxhathisa kwe-DC yocingo olubini ku + 20 ° C malunga. 81 Ω / km. – I-inductance imalunga. 3 μH / m. – Ubuchule bumalunga. 70 nF/km. |
|
| Impembelelo yokuchasa | Uqikelelo lokuchasana okongeziweyo kwisekethe yi-10 Ω. Ubude obuninzi bu (75 Ω – 10 Ω) / (81 Ω / km) = 800 m. |
| Impembelelo ye-inductance kunye ne-capacitance ye-800 m cable yile: | |
| Impembelelo ye-inductance | I-inductance iyonke yi-0,8 km x 3 μH / m = 2,4 mH. Ixabiso lesamba sentambo kunye
umz. isivamvo se-SET/OS2 [Li = 30 μH] yi-2,43 mH. Umlinganiselo we-L / R ngaloo ndlela u-2,4 mH / (75 - 10) Ω = 37 μH / Ω, ongaphantsi kwexabiso eliphezulu elivumelekileyo 116,5 μH / Ω. |
| Impembelelo yesakhono | Umthamo wekhebula yi-0,8 km x 70 nF/km = 56 nF. Ixabiso elidityanisiweyo lentambo kunye nomzekelo, i-SET/OS2 sensor [Ci = 3 nF] yi-59 nF. |
| Xa kuthelekiswa namaxabiso kwitheyibhile 2, sinokushwankathela ukuba amaxabiso angentla awathinteli ukusetyenziswa kwale ntambo ye-800 m kumaqela okuqhuma i-IIB okanye i-IIC.
Ukwenzeka kwezinye iindidi zekhebula kunye neenzwa zemigama eyahlukeneyo zingabalwa ngokufanelekileyo. |
