Ni ubuhe buryo bwo kohereza？
Inzira zohereza ni kimwe mubintu bigaragara muri sisitemu yo gukwirakwiza amashanyarazi. Bashyigikira abayoboraikoreshwa mu gutwara ingufu z'amashanyarazi ziva mumasoko kugeza kubakiriya. Imirongo yohereza itwara amashanyarazi igihe kirekireintera kuri voltage nyinshi, mubisanzwe hagati ya 10kV na 500kV.
Hariho ibishushanyo byinshi bitandukanye byuburyo bwo kohereza. Ubwoko bubiri busanzwe ni:
Amashanyarazi ya Lattice (LST), bigizwe nurwego rwibyuma bigize ibice byubatswe bigizwe cyangwagusudira hamwe
Imiyoboro y'ibyuma (TSP), aribyuma bidafite ibyuma byahimbwe nkigice kimwe cyangwa nkibice byinshi byashyizwehohamwe.
Urugero rwa 500 - kV umuzenguruko umwe LST
Urugero rwa 220-kV kabiri-izunguruka LST
LSTs na TSPs zombi zirashobora gushushanywa gutwara amashanyarazi imwe cyangwa ebyiri z'amashanyarazi, byitwa ko ari umuzenguruko umwe hamwe nuburyo bubiri (reba ingero hejuru). Inzira ebyiri zumuzunguruko mubisanzwe zifata abayobora muburyo buhagaritse cyangwa butondekanye, mugihe imiterere yumuzunguruko umwe isanzwe ifata abayobora mu buryo butambitse. Bitewe nuburyo buhagaritse bwimikorere yabayobora, ibyerekezo bibiri-byumuzingi muremure kuruta urwego rumwe. Kumurongo wo hasi wa voltage, imiterere rimwe na rimwewitwaze imirongo irenga ibiri.
Umuzunguruko umweguhinduranya imiyoboro (AC) umurongo wohereza ufite ibyiciro bitatu. Kuri voltage nkeya, icyiciro mubisanzwe kigizwe numuyoboro umwe. Kuri voltage ndende (hejuru ya 200 kV), icyiciro gishobora kuba kigizwe nabayobora benshi (bahujwe) batandukanijwe nicyogajuru kigufi.
Inzira ebyiriUmurongo wohereza AC ufite ibice bibiri byibyiciro bitatu.
Iminara yapfuye ikoreshwa aho umurongo wohereza urangirira; aho umurongo wohereza uhindukira ku nguni nini; kuruhande rumwe rwambukiranya runini nkumugezi munini, umuhanda munini, cyangwa ikibaya kinini; cyangwa intera ikurikira ibice bigororotse kugirango itange inkunga yinyongera. Umunara wapfuye utandukanye numunara uhagarikwa kuko wubatswe kugirango ukomere, akenshi ufite umusingi mugari, kandi ufite imirongo ikomeye ya insulator.
Ingano yimiterere iratandukanye bitewe na voltage, topografiya, uburebure bwa span, nubwoko bw umunara. Kurugero, imirongo ibiri-500-kV LSTs mubusanzwe ifite uburebure bwa metero 150 kugeza hejuru ya 200, naho umunara umwe-500-kV umunara muri rusange ufite uburebure bwa metero 80 na 200.
Inzira ebyiri zuzuzanya ni ndende kuruta imiterere yumuzunguruko umwe kuko ibyiciro bitunganijwe neza kandi icyiciro cyo hasi kigomba gukomeza byibuze ubutaka butagaragara, mugihe ibyiciro bitunganijwe muburyo butambitse kumurongo umwe. Mugihe imbaraga za voltage ziyongera, ibyiciro bigomba gutandukanywa nintera ndende kugirango wirinde amahirwe yose yo kwivanga cyangwa guterana. Kubwibyo, iminara ya voltage ndende hamwe ninkingi birebire kandi bifite amaboko yagutse atambitse kurenza imiterere ya voltage yo hasi.
