Mundima yeinjiniya yemagetsi, kusarudzwa kwetambo dzakakwirira-voltage uye yakaderera-voltage kwakakosha kuti ive nechokwadi chekuchengetedza, inoshanda uye yakavimbika kufambisa kwemagetsi. Kunzwisisa misiyano yakakosha pakati pemhando mbiri idzi dzetambo dzinogona kubatsira mainjiniya, vemagetsi, uye mamaneja epurojekiti kuita sarudzo dzine ruzivo nezvekushandisa kwavo chaiko.
Tsanangudzo uye voltage range
High voltage cablesdzakagadzirirwa kutakura ikozvino pamagetsi anowanzo pamusoro pe1,000 volts (1 kV). Idzi tambo dzakakosha pakufambisa magetsi panzendo refu, sekubva pazviteshi zvemagetsi kuenda kune zviteshi zvishoma kana pakati pezviteshi nekugovera network. Zvishandiso zvakajairika zvinosanganisira tambo dzemagetsi epamusoro uye masisitimu ekufambisa epasi pevhu.
Low-voltage cables, kune rumwe rutivi, inoshanda pamagetsi ari pasi pe1,000 volts. Ivo vanowanzoshandiswa mukuvheneka, kugovera simba uye kutonga masisitimu munzvimbo dzekugara, dzekutengesa uye dzeindasitiri. Semuyenzaniso, tambo dzinoshandiswa mumba wiring, mwenje matunhu uye diki michina.
Kuvaka uye zvinhu
Chimiro chetambo dze-high-voltage yakaoma kupfuura iyo ye-low-voltage cables. High-voltage tambo dzinowanzo sanganisira akawanda akaturikidzana, anosanganisira conductor, insulators, nhovo uye ekunze sheaths. Insulating zvinhu zvakakosha kudzivirira kubuda uye kuve nechokwadi chekuchengetedza. Zvishandiso zvinogara zvichishandiswa mumatambo akakwira-voltage zvinosanganisira cross-linked polyethylene (XLPE) uye ethylene-propylene rubber (EPR).
Low voltage tambo dzinowanzo kuve nyore mukugadzira, kunyangwe dzichiri kuda zvemhando yepamusoro. Ivo kazhinji insulated vachishandisa PVC (polyvinyl chloride) kana rabha, iyo inokwana kuti yakaderera voltage ratings. Conductor zvinhu zvinogona kusiyana, asi mhangura nealuminium ndiyo inonyanya kusarudzwa yeakakwira uye yakaderera voltage application.
Kuita uye kuchengeteka
High-voltage cablesdzakagadzirwa kuti dzikwanise kumirisana nemamiriro akanyanya, kusanganisira tembiricha yakakwira, kushushikana kwemagetsi uye mamiriro ekunze. Ivo vanowanzoyedzerwa simba re dielectric, iro rinoyera kugona kwetambo kuramba kuparara kwemagetsi. Izvi zvakakosha kuve nechokwadi chekuchengetedza uye kuvimbika kweiyo magetsi ekufambisa system.
Kusiyana neizvi, tambo dzepasi-voltage dzakagadzirirwa nzvimbo dzisinganyanyi kudiwa. Kunyange vachiri kuda kuzadzisa zviyero zvekuchengetedza, zvinodikanwa zvekushanda hazvina kuomarara setambo dzepamusoro-voltage. Nekudaro, tambo dzemagetsi dzakaderera dzinofanira kuramba dzichienderana nemakodhi emagetsi emunharaunda uye mirau kuti ive nechokwadi chekushanda kwakachengeteka.
Application
Iko kushandiswa kwe-high-voltage cables uye low-voltage cables zvakasiyana zvikuru. High voltage cables anonyanya kushandiswa mukugadzira magetsi, kutumira uye kugovera masisitimu. Izvo zvakakosha pakubatanidza magetsi emagetsi emagetsi akadai semhepo uye mapurazi ezuva kune grid.
Zvisinei, tambo dzepasi-voltage dzinowanikwa kwose kwose muupenyu hwezuva nezuva. Izvo zvinoshandiswa mukugara wiring, zvivakwa zvekutengeserana uye zvivako zvemaindasitiri kuvhenekera, kupisa uye simba zvakasiyana-siyana zvekushandisa. Kushanda kwavo kwakasiyana-siyana kunoita kuti vave vakakodzera kushandiswa kwakasiyana-siyana, kubva kumatunhu akareruka emumba kusvika kune yakaoma kudzora masisitimu mumiti yekugadzira.
mukupedzisa
Muchidimbu, kusarudzwa kwe-high-voltage uye low-voltage cables kunoenderana nezvinodiwa zvakananga zvehutano hwemagetsi. High-voltage cables akakosha pakufambiswa kwemagetsi zvakanaka pamadaro marefu, nepo tambo dzepasi-voltage dzakakosha pakushandiswa kwemagetsi kwemazuva ese. Kunzwisisa misiyano yakakosha mukuvaka, kuita, uye kushandisa kunogona kubatsira nyanzvi kuita sarudzo dzine ruzivo kuti ive nechokwadi chekuchengetedza uye kuvimbika kwemasisitimu avo emagetsi. Kunyangwe iwe uri kugadzira gidhi nyowani yemagetsi kana waya yekumba, kuziva nguva yekushandisa yakakwirira-voltage uye yakaderera-voltage tambo zvakakosha kuti ubudirire.
