Intangiriro kubumenyi bwibanze bwikingira ikingira icyuma nicyuma gikingira icyuma

Ikirindiro cyo gukingira (nanone cyitwa imbere gukingira imbere, igice cyimbere cyimbere)

Umuyoboro ukingira icyuma ni icyuma kitari icyuma gisohoka ku muyoboro wa kabili, kikaba gifite ibikoresho hamwe nuyobora kandi kikaba gifite ubushobozi bwo guhangana na 100 ~ 1000Ω • m.Ibikoresho hamwe nuyobora.

Mubisanzwe, insinga nke za voltage ya 3kV no munsi yazo ntizifite urwego rukingira ikingira, kandi insinga ziciriritse n’umuvuduko mwinshi wa 6kV no hejuru zigomba kuba zifite urwego rukingira.

Imikorere yingenzi ya kiyobora ikingira: gukuraho ubusumbane bwubuso;kuvanaho ingaruka zingirakamaro hejuru yuyobora;kurandura imyenge iri hagati yuwayobora na insulation;kora kiyobora hamwe na insulation muburyo bwa hafi;kunoza ikwirakwizwa ryumuriro wamashanyarazi hafi yuyobora;kumurongo uhuza imiyoboro ya kabili ikingira ikingira, ifite kandi umurimo wo kubuza imikurire yibiti byamashanyarazi no gukingira ubushyuhe.

Igice cyo kubika (nanone cyitwa insulasiyo nkuru)

Ibyingenzi byingenzi bya kabili bifite imikorere yihariye yo guhangana na sisitemu ya voltage.Mugihe cyubuzima bwa serivisi ya kabili, igomba kwihanganira voltage yagabanijwe hamwe na volvoltage mugihe cyananiranye na sisitemu igihe kinini, umurabyo utera imbaraga, kugirango harebwe niba nta muvandimwe cyangwa icyiciro cya kabiri cyangirika kibaho mugihe cya leta ikora ubushyuhe.Kubwibyo, ibikoresho nyamukuru byo kubika ni urufunguzo rwubwiza bwa kabili.

Guhuza polyethylene ni ibikoresho byiza byo kubika, ubu bikoreshwa cyane.Ibara ryacyo ni ubururu-bwera kandi bworoshye.Ibiranga ni: kurwanya izirinda cyane;gushobora kwihanganira ingufu nyinshi zingana na pulse amashanyarazi yamenetse imbaraga;igihombo gito cya dielectric tangent;imiti ihamye;ubushyuhe bwiza bwo kurwanya ubushyuhe, igihe kirekire cyemewe cyo gukora ubushyuhe bwa 90 ° C;ibikoresho byiza bya mashini, gutunganya byoroshye no kuvura inzira.

Inkingi yo gukingira (nanone yitwa igice cyo gukingira hanze, igice cya kabiri cyayobora)

Igikoresho cyo gukingira icyuma ni igikoresho kitari icyuma gisohoka ku cyerekezo nyamukuru cya kabili.Ibikoresho byayo kandi ni ibikoresho bifitanye isano hamwe na kimwe cya kabiri cyayobora hamwe nubunini bwa 500 ~ 1000Ω • m.Nibikoresho byose hamwe no kurinda ubutaka.

Mubisanzwe, insinga nke za voltage ya 3kV na munsi ntizifite urwego rukingira izirinda, kandi insinga ziciriritse n’umuvuduko mwinshi wa 6kV no hejuru zigomba kugira urwego rukingira.

Uruhare rwikingira ryikingira: inzibacyuho hagati yimigozi nyamukuru ya kabili hamwe nicyuma gikingira icyuma, kugirango bahuze cyane, bikureho icyuho kiri hagati yizuba hamwe nuyobora;kura ingaruka zingirakamaro hejuru yubutaka bwa kaseti y'umuringa;kunoza ikwirakwizwa ryumuriro wamashanyarazi hafi yubuso.

Gukingira izigabanyijemo ibice byamburwa kandi bidashobora kwamburwa ukurikije inzira.Kumugozi wa voltage uciriritse, ubwoko bwamburwa bukoreshwa kuri 35kV no munsi.Gukingira neza gukingirwa gukingirwa bifite gufatana neza, kandi nta bice bitwara igice bigumaho nyuma yo kwiyambura.Ubwoko budashobora kwamburwa bukoreshwa kuri 110kV no hejuru.Igice cyo gukingira kidashobora kwamburwa kirahujwe cyane hamwe n’ibikorwa nyamukuru, kandi ibyangombwa byo kubaka birarenze.

Icyuma gikingira icyuma

Icyuma cyo gukingira icyuma gipfunyitse hanze yikingira.Icyuma gikingira icyuma muri rusange gikoresha kaseti y'umuringa cyangwa insinga z'umuringa.Nuburyo bwingenzi bugabanya umurima wamashanyarazi imbere yumugozi kandi urinda umutekano wumuntu.Nubundi buryo bwo gukingira ikingira ikingira insinga zituruka kumashanyarazi.

Iyo ikosa ryihuta cyangwa rigufi ryumuzunguruko bibaye muri sisitemu, icyuma gikingira icyuma ni umuyoboro wumuyoboro mugufi.Agace kambukiranya ibice kagomba kubarwa no kugenwa hakurikijwe sisitemu ubushobozi buke bwumuzunguruko hamwe nuburyo bwo kutagira aho bubogamiye.Mubisanzwe, agace kambukiranya igice cyo gukingira kibarwa kuri sisitemu ya 10kV birasabwa kuba munsi ya milimetero kare 25.

Mu murongo wa kabili ya 110kV no hejuru, icyuma gikingira icyuma kigizwe nicyuma cyicyuma, gifite amashanyarazi yumurima wumuriro ndetse nakazi ko gufunga amazi, kandi gifite ninshingano zo kurinda imashini.

Ibikoresho n'imiterere y'icyuma muri rusange bifata ibyuma bya aluminiyumu;icyuma cy'umuringa;icyuma gisize ibyuma;icyuma cyitwa gurş, nibindi. Byongeye kandi, hariho icyatsi kibumbiye hamwe, nuburyo imiterere ya aluminiyumu ifatanye na PVC na PE sheaths, ikoreshwa cyane mubicuruzwa byu Burayi na Amerika.

Intwaro

Icyuma cyintwaro yicyuma kizengurutswe imbere imbere, muri rusange ukoresheje ibyuma bibiri bya galvanised ibyuma byumukandara.Igikorwa cyayo ni ukurinda imbere yumugozi no gukumira ingufu ziva hanze zangiza umugozi mugihe cyo kubaka no gukora.Ifite kandi umurimo wo kurinda ubutaka.

Ikirwanisho c'intwaro gifise inyubako zitandukanye, nk'intwaro z'icyuma, ibirwanisho bidafite ingese, ibirwanisho bitari ibyuma, n'ibindi, bikoreshwa muburyo bwihariye bwa kabili.
