Nigute wuzuza ibisabwa byubaka insinga?

Umugozi wubatswe

Mbere yo gushyira umugozi, banza umenye niba insinga yangiritse kandi niba insinga idahwitse.Ku nsinga za 3kV no hejuru, hagomba gukorwa ikizamini cya voltage.Ku nsinga ziri munsi ya 1kV, meghmmeter ya 1kVirashobora gukoreshwa mugupima ubukana bwokwirinda.Agaciro ko kurwanya insulasi muri rusange ntabwo kari munsi ya 10MΩ.

Mbere yo gutangira imirimo yo gucukura imiyoboro ya kabili, imiyoboro yo munsi y'ubutaka, ubwiza bwubutaka hamwe nubutaka bwahantu hubatswe bigomba kumvikana neza.Iyo ucukura imyobo ahantu hafite imiyoboro yo munsi, hagomba gufatwa ingamba zo gukumira ibyangiritse.Iyo ucukura imyobo hafi yinkingi cyangwa inyubako, hagomba gufatwa ingamba zo kwirinda gusenyuka.

Ikigereranyo cya kabili igoramye radiyo na diameter yo hanze ntigomba kuba munsi yindangagaciro zikurikira:

Ku mpapuro zashizwemo amashanyarazi menshi-insinga, icyuma kiyobora ni inshuro 15 naho aluminiyumu ni inshuro 25.

Ku mpapuro zashizwemo insinga imwe-yamashanyarazi, icyuma cyambere hamwe na aluminiyumu byombi inshuro 25.

Kumugozi wigenzura wimpapuro, icyuma kiyobora ni inshuro 10 naho aluminiyumu ni inshuro 15.

Kuri reberi cyangwa plastike iringaniye insinga nyinshi cyangwa insinga imwe, umugozi wintwaro ni inshuro 10, naho umugozi udafite intwaro ni inshuro 6.

Kubice bigororotse byumurongo wa kabili ushyinguwe, niba nta nyubako ihoraho, ibiti bya marikeri bigomba gushyingurwa, kandi ibimenyetso byerekana ibimenyetso nabyo bigomba gushyingurwa kumpande no mu mfuruka.

Iyo 10kV yamavuta yatewe impapuro zashizwemo insinga z'amashanyarazi zubatswe mubihe byubushyuhe bwibidukikije munsi ya 0℃, uburyo bwo gushyushya bugomba gukoreshwa kugirango ubushyuhe bwibidukikije cyangwa gushyushya umugozi unyuze hejuru.Iyo ushyushye unyuze mumashanyarazi, agaciro kariho ntigomba kurenza agaciro kagereranijwe kemewe numuyoboro, kandi ubushyuhe bwubuso bwumugozi ntibugomba kurenga 35℃.

Iyo uburebure bwumurongo wa kabili butarenze uburebure bwabakora, umugozi wose ugomba gukoreshwa kandi ingingo zigomba kwirindwa bishoboka.Niba ingingo zikenewe, zigomba kuba ziri kuri manhole cyangwa mu ntoki z'umuyoboro wa kabili cyangwa umuyoboro wa kabili, kandi ugashyirwaho ikimenyetso neza.

Intsinga zashyinguwe munsi yubutaka zigomba kurindwa nintwaro hamwe na anti-ruswa.

Ku nsinga zashyinguwe mu buryo butaziguye, hepfo yu mwobo hagomba gutunganywa no guhuzwa mbere yo gushyingura.Agace kegereye insinga kagomba kuzuzwa nubutaka bwiza bwa mmmm 100mm.Ubutaka bugomba gutwikirizwa isahani ihamye, kandi ingingo zo hagati zigomba kurindwa ikoti rya beto.Intsinga ntizigomba gushyingurwa mubutaka hamwe n imyanda.

Ubujyakuzimu bw'insinga zashyinguwe mu buryo butaziguye bwa 10kV no munsi yazo muri rusange ntabwo ziri munsi ya 0.7m, kandi ntabwo ziri munsi ya 1m mu murima.

Intsinga zashyizwe mumurongo wa kaburimbo hamwe na tunel zigomba gushyirwaho ibimenyetso kumpera zerekeza hanze, guterimbere, guhuza intera hamwe n’aho icyerekezo gihinduka, byerekana ibisobanuro bya kabili, imiterere, imizunguruko hamwe nogukoresha mukubungabunga.Iyo umugozi winjiye mu mwobo cyangwa mu nzu, urwego rwo kurwanya ruswa rugomba kwamburwa (usibye kurinda imiyoboro) hanyuma hagashyirwaho irangi rirwanya ingese.

Iyo insinga zashyizwe mumashanyarazi ya beto, hagomba gushyirwaho manholes.Intera iri hagati ya manholes ntigomba kurenza 50m.

Manholes igomba gushyirwaho mumurongo wa kabili ahari imigozi, amashami, amariba yamazi, hamwe nibibanza bitandukanye muburebure bwubutaka.Intera iri hagati ya manholes mu bice bigororotse ntigomba kurenga 150m.

Usibye udusanduku two gukingira ibyuma bishimangira, imiyoboro ya beto cyangwa imiyoboro ikomeye ya pulasitike irashobora gukoreshwa nkumugozi wo hagati.

Iyo uburebure bwumugozi unyura mu muyoboro urinda uri munsi ya 30m, umurambararo wimbere wigice kigororotse cyigice gikingira ntigomba kuba munsi yikubye inshuro 1.5 umurambararo winyuma wa kabili, ntabwo uri munsi yinshuro 2.0 mugihe hari umwe uhetamye, kandi ntabwo ari munsi ya 2,5 mugihe hari ibice bibiri.Iyo uburebure bw'umugozi unyura mu muyoboro urinda burenze 30m (bigarukira ku bice bigororotse), umurambararo w'imbere w'igitereko kirinda ntugomba kuba munsi ya 2,5 z'umurambararo w'inyuma wa kabili.

Ihuza ry'insinga z'insinga zigomba gukorwa no guhuza uruziga.Intoki z'umuringa zigomba guhondagurwa cyangwa gusudwa n'intoki z'umuringa, naho intoki za aluminiyumu zigomba guhuzwa n'intoki za aluminium.Inzibacyuho y'umuringa-aluminium ihuza imiyoboro igomba gukoreshwa muguhuza insinga z'umuringa na aluminium.

Intsinga zose za aluminiyumu ziranyeganyega, kandi firime ya oxyde igomba gukurwaho mbere yo guhonyora.Imiterere rusange yintoki nyuma yo gutombora ntigomba guhindurwa cyangwa kugororwa.

Intsinga zose zashyinguwe munsi yubutaka zigomba kugenzurwa kubikorwa byihishe mbere yo kuzuza, kandi hagomba gushushanywa igishushanyo cyo kwerekana umurongo ngenderwaho wihariye, ahantu hamwe nicyerekezo.

Gusudira ibyuma bidafite fer hamwe na kashe yicyuma (bakunze kwita kashe ya sisitemu) bigomba kuba bikomeye.

Kugirango ushyire umugozi wo hanze, mugihe unyuze mumaboko ya kabili cyangwa manhole, buri cyuma kigomba gushyirwaho ikimenyetso cya plastiki, kandi intego, inzira, ibisobanuro bya kabili hamwe nitariki yo gushyiramo umugozi bigomba gushyirwaho irangi.

Kumugozi wo hanze uhishe imishinga yo gushiraho, igishushanyo cyo kurangiza kigomba gushyikirizwa ishami rishinzwe kubungabunga no gucunga neza igihe umushinga urangiye ugatangwa kugirango byemererwe.
