Munsi yikiraro cyambukiranya inyanja gihuza Akarere ka Beilun ka Ningbo n’izinga rya Meishan, inzoka esheshatu “inzoka zifeza zamashanyarazi” zigenda zerekeza ku kiraro kandi “zigana imbere” zerekeza ku cyambu cya Meishan.Muri kamena, hamwe nogutangiza umushinga wa 110 kV hamwe n’amazina 7 yo guhererekanya no guhindura, umuyoboro w’amashanyarazi wo mu nyanja uzohereza amashanyarazi ahoraho ku cyambu.
Mu mwaka wa 2008, Inama ya Leta yemeje ko hashyirwaho icyambu cya Ningbo Meishan gihuza icyambu, icyambu cya gatanu gihuza Ubushinwa nyuma ya Shanghai Yangshan, Tianjin Dongjiang, Dayaowan, na Yangpu, Hainan.Muri uwo mwaka, komite ya komine ya Ningbo na guverinoma y’amakomine bafashe icyemezo cyo kwihutisha iyubakwa ry’ikirwa cya Meishan.
Muri Nzeri 2009, imirimo yo kubaka imishinga itandukanye izwi ku izina rya “Meishan” yafunguwe ku kirwa cyose, ikirundo cyatangiye kubutaka burenga 400 mu bubiko, maze imirimo yo kubaka ibikorwa remezo birenga 10 iratangira.35 kV yonyine ya Meishan kuri iki kirwa irabura, kuburyo byihutirwa kubaka amashanyarazi.Kubera iyo mpamvu, ibiro by’amashanyarazi bya Ningbo byubahiriza ihame ry’ibikorwa bidasanzwe kandi bigashyira mu bikorwa gahunda idasanzwe yo kubaka amashanyarazi yagenewe ikirwa cya Meishan kugira ngo icyambu gikenewe mu iterambere rirambye.
Kubaka ikirwa "umuvuduko wamashanyarazi" kumubiri
Kubaka ingufu zidasanzwe bivuze ko buri sano kuva ubushakashatsi bushoboka, igishushanyo mbonera cyubwubatsi kizaba hafi yubwubatsi niterambere ryibikenewe byicyambu, kandi bivuze ko byuzuye, birambuye kandi byitondewe kubaka na serivisi.Mu ntangiriro za 2013, nyuma yimyaka 5 yimbaraga, umushinga wa 110 kV na 7-wohereza no guhindura ibintu byinjiye mubyiciro.Guhura n’ikirwa cyihuta cyiterambere, kurengera ibidukikije no kubungabunga umutungo byabaye umurimo ukomeye wa Biro y’amashanyarazi ya Ningbo.
"Urebye iterambere rirambye ry’icyambu cya Meishan, icyambu cyo hejuru muri kariya gace kirimo" kugeza hasi "guhinduka."Umuyobozi ushinzwe igishushanyo mbonera yatangije.Duhereye ku iterambere rirambye ry’akarere ka cyambu, imirongo isanzwe yo hejuru byanze bikunze izagira ingaruka kumiterere yikibuga cyikiraro cya Meishan hamwe niterambere ndetse no kubaka umurongo unyuze mukarere.
Kubwibyo, Ningbo Biro y’amashanyarazi irateganya mbere yigihe, kuruhande rumwe, ihindura imirongo yimbere mugace kiterambere igatera hasi;Ku ruhande rumwe, umugozi wa 110kV ufite igice cya 1000mm2 ukoreshwa mu gushyira inyanja yambukiranya bigoye cyane, kugirango uzamure “ubuziranenge bwakarere” kirwa cya Meishan ubuziranenge bwa tekiniki.
Ati: “Kugira ngo duhuze iterambere ry’izinga kandi duhuze ibiranga imizigo y’icyambu, duhitamo urwego rwa voltage rw’urusobe rwo gukwirakwiza akarere k’icyambu kuba kV 20.”Umuyobozi ushinzwe imishinga yavuze ko umushinga wo gukwirakwiza amashanyarazi wo gukwirakwiza amazina ya karindwi no guhindura ikirwa cya Meishan urimo kubakwa.
Mbere, mu rwego rwo kuzigama umutungo w’izinga no kugera ku bwiza bwiza bwo gutanga amashanyarazi, Biro y’amashanyarazi ya Ningbo yakusanyije ingufu za tekiniki, yagura ubushakashatsi kandi yongera ingufu mu bushakashatsi, kandi ihujwe rwose n’ibiranga ikirwa cya Meishan “kirekire mu burasirazuba-uburengerazuba, rugufi ruguru n'amajyepfo ”, rwasabye kubaka umuyoboro wa 20 kV ukwirakwiza ubwenge ku kirwa cya Meishan, no kugabanya Substation 110 kV iteganijwe muri iki kirwa kuva kuri 3 kugeza kuri 2, Umuyoboro w’inzira n'umutungo w'ubutaka wabitswe ku buryo bugaragara.
Gushyira “imiyoboro y'ingufu” mu cyambu hakurya y'inyanja
Muri Mata, umushinga wo gukwirakwiza umurongo uva kuri 220kV Xianxiang ganao umurongo t kugeza kuri 110 kV na transformateur yamazina 7 yinjiye mubyiciro bikomeye byo gushyiramo insinga zinyanja kumushinga wose.Iyi ntera ngufi ya 1.1km, yakoze insinga eshatu za mbere 110 kV muri Ningbo: gushyira umugozi hamwe nigice cya 1000m2 bikorwa kunshuro yambere, kubaka insinga bikorwa hamwe nikiraro cyambukiranya inyanja kunshuro yambere, nigikoresho cyo kwagura umugozi gishyirwaho ukurikije kwaguka guhuza ikiraro kunshuro yambere.Ubwubatsi bwubwubatsi bwahuye ningorane ningorane zitandukanye kuva mbere.
Hano hari inzira zihuta kumpande zombi z'ikiraro cya Meishan.Umwanya wo gushyiramo umugozi hagati yikiraro ni muto cyane.Buri gikoresho cyo kwagura umugozi gifite uburemere bwa toni 5 gihura ningorane zo kudashobora gushyirwaho nyuma yo kugera ahazubakwa “Bavandimwe, banza usenye, hanyuma ubiterane munsi.”Umuyobozi w'itsinda rya kabili, yewe Xuan, yavugije induru akoresheje ukuboko, ahita asenya igikoresho kimwe cyo kwagura umugozi mu buryo bworoshye kuzamura no kwimura ibice n'amaboko arenga 20.
Crane, igitugu, inshuro nyinshi hasi, muribi nabyo mugihe cyubukonje, abantu bose bamaze kubira icyuya.Nyuma yuko ibice bimaze kujyanwa ahabigenewe, kugirango bitagira ingaruka ku iyubakwa ryinyuma, abagize itsinda ryubwubatsi bamaze iminsi 5 "injangwe" mumwanya muto.Kimwe no kubaka, kusanya witonze ibikoresho bitanu byo kwagura.
Ikibazo cyibikoresho cyarakemutse, kandi ingorane nshya ziraza.Ku ya 12 Mata, mu muyaga wo guhiga ikiraro cya Meishan Island, umugozi wa kabili warahagaze, maze wowe hamwe n’abakozi benshi bubaka twongeye kuganira kuri gahunda yo kubaka.Ukurikije ubunararibonye bwakazi, umugozi wunamye urashobora kugerwaho ukoresheje itandukaniro ryimyanya igereranijwe hagati yabagorora.Ariko, nyuma yikigeragezo cyumurima, usanga kugorora biremereye kandi bitinda kugera kubikorwa.Metero 100 gusa nizo zishobora kubakwa buri munsi.Umugozi uzashyirwa muburyo bwinzoka ku kiraro ni metero 6000, bizatwara iminsi 60 kugirango urangire.Niki kigomba gukorwa niba umushinga wose utangiye gukoreshwa muri kamena?
Ati: "Ni ngombwa gushaka uburyo bwo kurangiza umurongo wa kabili mu gihe gito."Mu muyaga ukaze wo mu nyanja, abantu bose bumvise ijwi rikomeye rya Ye.Amasaha icumi, ibisubizo bitandatu, ibizamini byinshi, hanyuma, gahunda yo kubaka yo gukoresha intoki nkigikoresho cya orthopedic cable cyemewe.
“Umwe, babiri, batatu, haguruka!”Ibiganza 10 byicyatsi kibisi komeza urunigi kumurongo wa diameter, hanyuma ugerageze uko ushoboye kugirango ushakishe toni 9.Buhoro buhoro “inzoka nini” ya feza yagaragaye, kandi ubwubatsi bworoshye kandi bunoze nabwo bwagabanije igihe cyo kubaka kugeza ku minsi 10.
“Ikirwa cya Meishan cyahindutse ubwato bushya” bunini bw'inyanja “yo mu majyepfo y'uburasirazuba buturutse ku butayu butarimo ubutayu ndetse n'ubutaka butagira ingano mu myaka mike, kandi urufunguzo ni inkunga ikomeye y'amashanyarazi Akarere ka Beilun, akarere.
