Amandla avamile ikhebula le-fiber optic lasemoyeni faka Ikhebula le-ADSS kanye ne-OPGW. Namuhla sizokhuluma ngomehluko phakathi kwazo: I-ADSS VS I-OPGW.

I-OPGW imele i-Optical Ground Wire, esetshenziswa emigqeni yokudlulisa amandla. Yikhebula elisebenza ngezinhloso ezimbili, njengokuphatha i-fiber optics yokuxhumana kanye nokusebenza njengentambo yomhlabathi. Lokho kunengqondo ngoba izintambo zikagesi zidinga isisekelo ukuze zivikeleke embaneni nokunye okunjalo. Ngakho-ke i-OPGW cishe ihlanganisa umsebenzi wokusekela phansi kanye nekhono lokudlulisa idatha.

I-ADSS ingenye indlela efingqiwe. I-ADSS imele i-All-Dielectric Self-Supporting. I-All-dielectric isho ukuthi ayinazo izingxenye zensimbi, ngakho-ke ayihambisi ugesi. Ukuzisekela kusikisela ukuthi ayidingi izakhiwo zokusekela zangaphandle; ingathwala isisindo sayo. Ngakho-ke izintambo ze-ADSS cishe zisetshenziselwa ukuxhumana, kodwa zifakwe ngokwehlukana nezintambo zikagesi. Mhlawumbe zisetshenziswa ezindaweni lapho ungakwazi ukuzinamathisela khona ezintanjeni zikagesi, njengasemigwaqweni noma ezinsikeni ezihlukene.

Manje, ukuze sihlukanise umehluko. Ake siqale ngesakhiwo. I-OPGW inezintambo ezibonakalayo ngaphakathi kwebhokisi elivikelayo, elizungezwe izinto eziqhubayo njenge-aluminium noma insimbi. Lokhu kuyivumela ukuthi isebenze njengentambo yomhlabathi. I-ADSS, njengoba iyi-dielectric kuphela, ingaba nezintambo ezintweni ze-dielectric, mhlawumbe ezinezintambo ze-aramid zamandla, futhi azinazo izingxenye zensimbi. Ngakho-ke ngokwesakhiwo, i-OPGW inensimbi, i-ADSS ayinayo.

Ukufakwa:
I-OPGW ifakwe phezulu kwemibhoshongo yokudlulisa, ithatha indawo yentambo yendabuko engaguquki (intambo yomhlabathi). Njengoba iyingxenye yengqalasizinda yezintambo zikagesi, ihlanganiswe ezindaweni ezinama-voltage aphezulu. Ngakolunye uhlangothi, i-ADSS ifakwe yodwa. Ingase ibe sezigxotsheni zocingo, eduze kwezakhiwo ezikhona, kodwa hhayi ezintanjeni zikagesi ngokwazo. Akudingeki ibe yingxenye yesistimu kagesi, ngakho-ke kuphephile ukuyiphatha ezindaweni ezingenawo ama-voltage aphezulu.

Izicelo:
I-OPGW isetshenziswa emigqeni yokudlulisa ene-voltage ephezulu lapho kudingeka khona kokubili i-grounding kanye nokuxhumana. Iyingxenye yengqalasizinda yegridi yamandla. I-ADSS isetshenziswa emigqeni yokusabalalisa, mhlawumbe izimo ze-voltage ephansi, noma lapho ungakwazi ukufaka khona emigqeni yamandla kagesi. Yenzelwe amanethiwekhi okuxhumana azimele, mhlawumbe ezindaweni zasemadolobheni noma emigwaqweni lapho kusetshenziswa khona izigxobo ezihlukene.

Izakhiwo zikagesi:
I-OPGW iyaphehla ugesi futhi iyingxenye yesistimu kagesi, ngakho-ke kufanele iphathe ama-voltage aphezulu kanye nemisinga, okuhlanganisa nemisinga yephutha. I-ADSS ayiphehli ugesi, ngakho-ke ayithinteki ekuphazamisekeni kukagesi futhi ayibeki ingozi yokuqhuba ugesi. Lokho kuyenza iphephe ezindaweni ezithile.

Amandla okusebenza ngomshini:
Zombili zidinga ukuqina. I-OPGW inezendlalelo zensimbi ezinikeza amandla nokuvikelwa. I-ADSS ithembele ezintweni ze-dielectric kanye mhlawumbe ne-Kevlar ukuze ikwazi ukudonsa amandla. Njengoba i-ADSS izisekela ngokwayo, kumele iklanywe ukuthi ikwazi ukusingatha isisindo sayo ngaphandle kokugoba, ngisho nangesikhathi eside. I-OPGW, njengoba iyingxenye yomugqa kagesi, iklanywe ukuthi imelane nokucindezeleka okufanayo kwemvelo njengezinto eziqhuba ugesi, njengomoya, iqhwa, kanye nokushintsha kwezinga lokushisa.

Izici zemvelo:
I-OPGW ifakwe ezindaweni ezifanayo ezinzima njengezintambo zikagesi, ngakho-ke yakhelwe ukuqina ngokumelene nombani, ama-voltage aphezulu, kanye nokucindezeleka komshini. I-ADSS ingase isetshenziswe ezindaweni ezingatheni kakhulu, kodwa kusadingeka imelane nesimo sezulu. Njengoba i-dielectric yonke, akudingeki ikhathazeke ngokugqwala kwe-galvanic noma umbani oqhubayo, kodwa idinga ukumelana nemisebe ye-UV kanye nomonakalo ongokwenyama.

Izindleko kanye nokugcinwa:
I-OPGW ingase ibe nezindleko ezingcono uma yakha imigqa emisha kagesi noma ithuthukisa ekhona ngoba isebenzela izinjongo ezimbili. Kodwa-ke, ukufakwa kungadinga ubuchwepheshe bemigqa kagesi kanye nesikhathi sokungasebenzi. I-ADSS ingaba eshibhile ezimweni lapho kungadingeki ukuthi ushintshe ingqalasizinda yamandla ekhona, vele ungeze izintambo ezintsha ezigxotsheni ezihlukene. Ukulungiswa kwe-OPGW kuzobandakanya ukubhekana negridi yamandla, okungaba yinkimbinkimbi, kuyilapho i-ADSS ingaba lula njengoba ihlukile.

Ezinye izinto okufanele uzicabangele:
I-ADSS ingase ibe nezinkinga nge-arcing yebhendi eyomile uma ifakiwe eduze kwemigqa ye-voltage ephezulu, ngoba noma ingahambisani nogesi, ama-voltage abangelwayo angabangela izinkinga. I-OPGW isivele iyingxenye yesistimu kagesi, ngakho-ke yenzelwe ukusingatha lezo zinkinga. Ubude be-span bungahluka futhi. I-OPGW isetshenziswa kuma-span amade ajwayelekile emibhoshongweni ye-voltage ephezulu, kuyilapho i-ADSS ingase ibe namakhono e-span ahlukene ngokusekelwe ekwakhiweni kwayo.

Linda, kufanele ngiqinisekise ukuthi i-ADSS isetshenziswa ngempela yini emigqeni yokusabalalisa. Ngicabanga ukuthi imigqa yokusabalalisa inamandla aphansi, njengalawo aletha ugesi emakhaya, ngakho-ke mhlawumbe i-ADSS isetshenziswa lapho ngoba imvelo ayidingi kakhulu. I-OPGW ngokuqinisekile iwukudlulisela amandla aphezulu.

Futhi, ukuhlukaniswa kwamandla kagesi: I-ADSS ayihambisi ugesi, ngakho-ke ingafakwa eduze kwezintambo zikagesi ngaphandle kwengozi, kodwa i-OPGW iyingxenye yesistimu yokumisa phansi yentambo kagesi. Ngakho-ke i-ADSS ingcono ekugwemeni ukuphazamiseka kwe-electromagnetic.

Ngokuphathelene nesikhathi sokufakwa, i-OPGW ingadinga ukuthi ulayini kagesi uncishiswe amandla noma usebenzele kuwo ngabasebenzi abakhethekile, kanti i-ADSS ingafakwa ngabasebenzi bezokuxhumana ngaphandle kokuthinta ingqalasizinda yamandla.

Ngakho-ke uma konke kuhlanganiswe ndawonye, ​​umehluko omkhulu usekwakhekeni kwawo (insimbi vs. okungeyona eyensimbi), indawo yokufaka (ehlanganiswe nezintambo zikagesi vs. ezihlukene), izakhiwo zikagesi (eziqhuba ugesi vs. ezingenzi ugesi), kanye nezindawo zokusetshenziswa (ukudluliselwa kwamandla aphezulu vs. i-voltage ephansi noma amanethiwekhi okuxhumana ahlukene).
