Umehluko phakathi kwe-DC Cables kanye ne-AC Cables

电缆

1. Amasistimu Okusebenzisa Ahlukene:

Izintambo ze-DCasetshenziswa ezinhlelweni zokudlulisa zamanje eziqondile ngemuva kokulungiswa, kuyilapho izintambo ze-AC zivame ukusetshenziswa ezinhlelweni zamandla ezisebenza kumafrikhwensi ezimboni (50Hz).

2. Ukulahleka Kwamandla Aphansi Ekudluliselweni:

Uma kuqhathaniswa nezintambo ze-AC, izintambo ze-DC zibonisa ukulahleka kwamandla okuncane phakathi nenqubo yokudlulisa. Ukulahlekelwa kwamandla kumakhebuli e-DC ngokuyinhloko kungenxa yokumelana okuqondile kwamanje kwamakhondatha, nokulahlekelwa kokufakwa kwe-insulation kube kuncane uma kuqhathaniswa (kuncike kubukhulu bokuguquguquka kwamanje ngemva kokulungiswa). Ngakolunye uhlangothi, ukumelana kwe-AC kwezintambo ze-AC ezinama-voltage aphansi kukhulu kancane kunokumelana ne-DC, futhi kumakhebula anamandla kagesi, ukulahlekelwa kubaluleke kakhulu ngenxa yomphumela wokusondela kanye nomthelela wesikhumba, lapho ukulahleka kokumelana nokufakwa kudlala indima enkulu, ikakhulukazi. okukhiqizwa yi-impedance kusuka ku-capacitance kanye ne-inductance.

3. Ukusebenza Okuphezulu Kokudlulisa kanye Nokulahleka Kwemigqa Ephansi:

Izintambo ze-DC zinikeza ukusebenza kahle kokudlulisela phambili kanye nokulahlekelwa kolayini okuncane.

4. Ilungele Ukulungisa Isikhombisi-ndlela Sokudluliswa Kwamandla Kwamanje Nokushintsha.

5. Naphezu kwezindleko eziphezulu zemishini yokuguqula uma kuqhathaniswa nama-transformer, izindleko zizonke zokusebenzisa izintambo ze-DC ziphansi kakhulu kunezintambo ze-AC. Izintambo ze-DC zine-bipolar, zinesakhiwo esilula, kuyilapho izintambo ze-AC ziyisistimu yezintambo ezine ezinezigaba ezine noma ezinhlanu ezinezidingo zokuphepha eziphezulu zokuvikela kanye nesakhiwo esiyinkimbinkimbi. Izindleko zezintambo ze-AC zingaphezu kokuphindwe kathathu kunezintambo ze-DC.

6. Ukuphepha Okuphezulu Ekusetshenzisweni Kwezintambo Ze-DC:

- Izici ezingokwemvelo zokudluliswa kwe-DC zenza kube nzima ukunxenxa yamanje kanye nokuvuza kwamanje, ukugwema ukuphazamiseka kazibuthe nezinye izintambo ezihlanganiswe ndawonye.

- Izintambo ezibekiwe ezinomgogodla owodwa azibi nakho ukulahlekelwa yi-magnetic hysteresis ngenxa yamathreyi ekhebula esakhiwo sensimbi, egcina ukusebenza kokudluliswa kwekhebula.

- Izintambo ze-DC zinamandla aphezulu wokuvikela i-short-circuit kanye ne-overcurrent.

- Uma amasimu kagesi kagesi afanayo asetshenziswa ekufakeni insimu, inkambu kagesi ye-DC iphephe kakhulu kunenkambu kagesi ye-AC.

7. Ukufaka Okulula, Ukunakekela Kalula, kanye Nezindleko Eziphansi zamakhebula e-DC.

 

I-InsulationIzidingo ze-AC efanayo ne-DC Voltage kanye nezamanje:

Uma i-voltage efanayo isetshenziswa ku-insulation, inkambu kagesi ezintamboni ze-DC incane kakhulu kunezintambo ze-AC. Ngenxa yomehluko obalulekile wesakhiwo phakathi kwezinkambu ezimbili, inkambu kagesi ephezulu ngesikhathi sokunika amandla ikhebula le-AC igxiliswa eduze kwe-conductor, kuyilapho kumakhebula e-DC, igxila kakhulu ngaphakathi kwesendlalelo sokufakwa. Ngenxa yalokho, izintambo ze-DC ziphephe kakhudlwana (izikhathi ezingu-2.4) lapho i-voltage efanayo isetshenziswa ekufakeni.
