Tsayo Masana'antu na Ikkita – EHV da HV Overhead Lines

Jirgin Kwallon Kirki da Jirgin Mai Tsakiyar Tsohon Rike

A cikin jirgin kwallon kirki, Yawan Kirki Mai Yawa (EHV, inda tsakar kirki V&ge;150 kV da Yawan Kirki Mai Yawa (HV, tare da 60 kV &le; V <150 kV) suna da amfani a matsayin yawan kirki na gajeruwa. Amfani da wadannan yawan kirki mai yawa ya haɗa da zama shi ne a yi taske kan tsakar kirki mai tsakiya. Daga Ingantaccen Joule, W=RI²t=UIt, inda W na nufin hanyoyin mutuwar zuwa maƙasa, R shine ƙaramin mai tsakiya, I shine tsakar kirki, t shine lokaci, da U shine yawan kirki. Ta haka, ta haka ƙara tsakar kirki, ya haɗa da zama shi ne a yi taske kan sararin mai tsakiya, kuma ya ƙara tsari da mutuwar zuwa maƙasa saboda hanyoyin Joule.

Jirgin gajeruwa suna faru daga manyan gwamnon kwallon kirki da mazaunin gwamnon. Idan jirgin mai tsakiya suka fi shahara a cikin abubuwa, a wurare, ana iya da muhimmanci a yi amfani da kable mai tsakiya masu tsaro saboda babban karfi da nasarorin cin kai.

Jirgin mai tsakiya na EHV da HV suna da muhimman abubuwa:

• Tsuron Kwallo: Wadannan sun bayyana faguwar jirgin mai tsakiya, zan iya hashe sararin mai tsakiya a kawo da tsayi da kyau.

• Masana'antar Kirki: Suna haɗe ƙarfin kirki daga sararin mai tsakiya zuwa tsuron kwallo, zan iya hashe ƙarfin kirki da dalilai.

• Sararin Mai Tsakiya: Su ke masu amfani a cikin jirgin mai tsakiya. Masu amfani a cikin sararin mai tsakiya sun hada da Aluminium Conductor Steel - Reinforced (ACSR), wanda ya ƙunshi European Standards kamar EN 50189, 50889, 61232, da 50182. Da sauka, akwai sararin aluminium alloy, kamar AAAC (all - aluminium alloy conductors cables) wadanda ake sanya da AL2, AL3, AL4, da AL5, a cikin EN 50182 da 50183.

• Misali Mai Zuba: Wadannan suka fi shahara a cikin abubuwan da suka fiye da tsaya.

• Juntukan Tsakiya: Wadannan suna hashe ƙarfin kirki da zan iya hashe hanyar tsakiya idan an samu abin da ba da shi.

Abubuwan jirgin gajeruwa suna da amfani don ƙara yawan mutuwar korona. Misalin mai zuba, kamar yadda aka bayyana a Figure 1, suna da muhimmiyar rawa a nan. Ta haka, ta haka suka haɗe yawan kirki zuwa ingantacce, suka ƙara yawan kirki zuwa ƙarshen da ba da korona, tare da ƙara yawan korona. Wannan ya ƙara da zama shi ne a ƙara yawan mutuwar korona, kuma ya ƙara yawan lafiya da yawan mutuwar da ba da shi, zan iya hashe inganci da ƙarshen jirgin gajeruwa.

Bincike Don Gajeruwa na Rai A Cikin Jirgin Mai Tsakiya da Ruhunsa OPGW Cables

Daga cikin abubuwan da suke da darasi ga jirgin mai tsakiya shine gajeruwa. Wadannan jirgin suke da darasi ga gajeruwa a duk lokacin, wanda ya haɗa da binciken da ake amfani a mazaunin gwamnon kwallon kirki zai ba da wuya. Ana bukatar amfani da misalai masu amfani don ƙara yawan bincike da dalilai a cikin jirgin gajeruwa.

Don ƙara wannan abu, "misalai mai bincike na rai" suna amfani a duk lokacin jirgin mai tsakiya. Daga cikin wadannan, Optical Power Ground Wire (OPGW) cables suna da amfani saboda abubuwan da suke da biyu. Cable OPGW na ƙarshen tubular wanda ake ƙunshi waɗannan optical single - mode fibers a fili. Wadannan fiber assembly na fili suna ƙunshi da layon-layon da ke da steel da aluminium wires.

Layon-layon na gaba na cable OPGW suna da muhimmiyar rawa a cikin bincike. Wadannan suna haɗe juntukan tsakiya daga mazaunin gwamnon zuwa mazaunin gwamnon, zan iya hashe hanyar tsakiya da ba da shi. Ta haka, ta haka suka haɗe sararin mai tsakiya zuwa ƙarshen da ba da gajeruwa, tare da ƙara yawan darasi ga jirgin mai tsakiya.

Daidai, waɗannan optical fibers a cikin cable OPGW suna da muhimmiyar rawa a cikin magana. Waɗannan fibers suna da amfani don magana da yawan godiya, tare da ƙara yawan hajinsu a cikin sector na kwallon kirki. Waɗannan suna da amfani don abubuwan da suke da al'amuran da kuma abubuwan da suke da magana, zan iya hashe inganci da ƙarshen power grid.

Waɗannan optical fibers suna da muhimmiyar rawa a cikin bincike, wanda ya ƙara yawan darasi ga jirgin mai tsakiya da gajeruwa. Waɗannan suna da ƙarshen da ba da shi, kuma ya ƙara yawan lafiya da yawan mutuwar da ba da shi. Da sauka, waɗannan optical fibers suna da ƙarshen da ba da shi, tare da ƙara yawan godiya da yawan godiya da ba da shi, zan iya hashe inganci da ƙarshen jirgin gajeruwa.

Figure 2 ya bayyana misali na cable OPGW, wanda ya nuna ƙarshen da ke da shi, tare da ƙara yawan bincike da abubuwan da suke da magana, tare da ƙara yawan bincike da dalilai a cikin jirgin mai tsakiya.

A wasu ƙasar, don jirgin mai tsakiya na shekaru da suka yi amfani a yawan kirki na 72.5 kV, ana amfani da hukumar bincike na rai. Tarihi, an yi amfani da waɗannan misalai na farko da uku ko duwa a cikin mazaunin gwamnon kwallon kirki, kuma an amfani Aluminium Conductor Steel - Reinforced (ACSR) cables. Amma, an yi ra'ayi wannan hukumomin. Cable Optical Power Ground Wire (OPGW) an zama zan iya amfani, saboda wadannan suna da amfani don ƙara yawan bincike, kuma suna da amfani don magana a cikin mazaunin gwamnon, zan iya hashe inganci da ƙarshen.

Kable-kable mai tsakiya suna da cross - linked polyethylene (XLPE) insulation. Waɗannan kable-kable suna da sararin aluminium, kuma suna da amfani a cikin abubuwan da suke da al'adu. Amfani da XLPE insulation ya ƙara yawan kirki, tsari, da ƙarshen, tare da ƙara yawan godiya.

Jirgin gajeruwa na Yawan Kirki Mai Yawa (EHV) da Yawan Kirki Mai Yawa (HV) suna da amfani da "ƙarshen ring". Kamar yadda aka bayyana a Figure 3, wannan ƙarshen ya ƙara yawan godiya. Ƙarshen ring ya ƙara yawan godiya da ƙarshen, tare da ƙara yawan godiya, kuma ya ƙara yawan godiya da ƙarshen, tare da ƙara yawan godiya da ƙarshen, tare da ƙara yawan godiya da ƙarshen, tare da ƙara yawan godiya da ƙarshen, tare da ƙara yawan godiya da ƙarshen, tare da ƙara yawan godiya da ƙarshen.
