Insulator ni iki?

Insulatorni igenzura ryihariye rishobora kugira uruhare runini mumirongo yohereza hejuru.Mu myaka ya mbere, insulatrice yakoreshwaga cyane ku nkingi zingirakamaro, hanyuma igenda ikura mu minara ihuza insinga nini cyane aho insuliranteri nyinshi zimeze nka disiki zimanikwa kumutwe umwe.Byakoreshejwe mu kongera intera yikururuka, ubusanzwe bikozwe mubirahuri cyangwa mubutaka, kandi byiswe insulator.Insulator zifite uruhare runini mumirongo yohereza hejuru, aribyo gushyigikira insinga no kubuza umuyaga gusubira mubutaka.Iyi mirimo yombi igomba kwemezwa.Insulator ntizigomba kunanirwa kubera imihangayiko itandukanye ya elegitoroniki iterwa nimpinduka zibidukikije hamwe nuburyo bwo gutwara amashanyarazi.Bitabaye ibyo, insulator ntizagira uruhare runini, kandi izangiza ubuzima bwa serivisi nubuzima bwimikorere kumurongo wose.

Imashini: Nibintu bikosora kandi bigahagarika insinga kumunara muburyo bwitaruye.Imashini zikoreshwa cyane mumashanyarazi yohereza amashanyarazi ni: insulirasi ya disiki imeze nka disiki, insulirantike yikirahure,

Guhagarika inkoniinsulator..

Mugihe habaye inkuba hamwe na flashovers zanduye, impanuka zo kugabanuka zikunda kugaragara, kandi zagiye zikurwaho buhoro buhoro..Nta bugenzuzi busabwa kugirango bubungabunge.Mugihe cyo kwiyiturika kwibice byibirahure bikonje, imbaraga za mashini zisigaye zizakomeza kugera kuri 80% byingufu zimena, zishobora gukomeza gukora neza kumurongo.Ntabwo hazabaho impanuka zikurikirana mugihe habaye inkuba hamwe na flashovers.Yakoreshejwe cyane mubice byanduye byicyiciro cya mbere nicyiciro cya kabiri..

Imashini ya farashi: Insulator zizwi cyane nk'amacupa ya farashi, ari insulator zikoreshwa mugushigikira insinga.Insulator irashobora kwemeza ko ihagije ihagije kubayobora, amaboko yambukiranya iminara.Igomba kuba ishobora kwihanganira umutwaro mu cyerekezo cyerekezo cyurugero rwumurongo hamwe nuburemere mubyerekezo bitambitse mugihe gikora.Irwanya kandi izuba, imvura, imihindagurikire y’ikirere hamwe na ruswa.Kubwibyo, insulator zigomba kuba zifite amashanyarazi meza nimbaraga zihagije.Ubwiza bwa insulator ni ngombwa cyane kubikorwa byumutekano byumurongo.Insulator zirashobora kugabanywa mugushigikira insulator, insulator zo guhagarika, insulator zirwanya umwanda hamwe nudukoko twa bushing ukurikije imiterere yabyo.Ukurikije intego, irashobora kugabanywamo mubice bitatu: insulator zumurongo, insimburangingo zunganira insimburangingo.Ukurikije ibikoresho bya insulator.Kugeza ubu hariho farashi, ibirahuri hamwe na insulirantike ikomatanya.Insulator zikoreshwa mumirongo yo hejuru zisanzwe zikoreshwa mumashanyarazi ya pin, insulator, ibinyugunyugu, insimburangingo, amasoko ya farashi, insulator hamwe nudukingirizo.Hariho ubwoko bubiri bwamashanyarazi mumashanyarazi: flashover no gusenyuka.Flashover iboneka hejuru ya insulator, kandi ibimenyetso byo gutwika birashobora kugaragara, ariko mubisanzwe imikorere ya insulation ntabwo yatakaye;gusenyuka bibaho imbere muri insulator, kandi gusohora bibaho binyuze mumubiri wa ceramic hagati yumutwe wicyuma nikirenge cyicyuma.Insulator zirashobora gusenywa burundu na arcing.Kumeneka, hagomba kwitonderwa kugenzura ibimenyetso bisohoka no gutwika ibirenge byicyuma.Kugirango wirinde umwanda nkumukungugu ureremba udafatana hejuru yubushakashatsi, hashyizweho inzira isenywa na voltage kumpande zombi za insulator, ni ukuvuga kunyerera.Kubwibyo, intera yubuso iriyongera, ni ukuvuga intera yikurikiranya, nintera isohoka hejuru yubuso, ni ukuvuga intera yamenetse, byitwa intera ndende.

Intera ya creepage = intera yubuso / voltage ntarengwa ya sisitemu.Ukurikije urugero rw’umwanda, intera igenda ni 31 mm / kuri kilovolt ahantu handuye cyane.Umuvuduko urashobora gucirwa urubanza ukurikije umubare wa insulator, muri rusange, 23 kuri 500kv;16 kuri 330kv;220kv 9;110kv 5;iyi niyo mibare ntarengwa, kandi hazaba imwe cyangwa ebyiri zindi.Imiyoboro ya 500kv ikoresha cyane cyane ikoresha ibice bine bigabanijwe, ni ukuvuga ko hari bine mugice kimwe, 220kv ikoresha imiyoboro irenga ibiri, naho 110kv ikoresha imwe.Imashini zigera kuri 1 ni 6-10KV, insulator 3 ni 35KV, imirongo 60KV ntabwo iri munsi yibice 5, insulator 7 ni 110KV, insulator 11 ni 220KV, insulator 16 ni 330KV;Insulator 28 rwose ni 500KV.Kuri insulator ya pin munsi ya 35KV, nta tandukaniro riri mumibare y'ibice.Imirongo ya 10KV isanzwe ikoresha 10-12m imwe ya sima inkingi hamwe na insulator.Intera igororotse hagati yinkingi ni 70-80m.Nta cyuma gihari cya 10KV, gusa inkingi ifite imirongo itatu yumuriro mwinshi.Bikunze kugaragara mu cyaro;Imirongo yo hejuru ya 35KV mubisanzwe ikoresha metero 15 imwe cyangwa inkingi ya sima ebyiri (nanone ukoreshe umubare muto wiminara mito yicyuma, uburebure buri muri metero 15-20) hamwe nibice 2-3 bya insulatrice, umurongo ugororotse hagati yinkingi Intera ni metero 120;220KV rwose ni umunara munini w'icyuma.Imirongo ya 220KV isanzwe ikoresha iminara yicyuma hejuru ya metero 30 nimirongo miremire ya insulator.Intera igororotse hagati yiminara yicyuma irenga metero 200.Gukoresha insulator: Gukora neza mumikorere yumuriro wamashanyarazi no kuzamura ubwizerwe bwamashanyarazi nikimenyetso cyingenzi mugusuzuma amasosiyete yingufu, kandi guhora ukoresha ibikoresho byubuhanga buhanitse nuburyo bwiza bwo gukemura iki kibazo.Nkigicuruzwa gishya, silicone rubber composite insulator ifite ibyiza byuburemere bworoshye, ubunini buto, anti-flashover, kurwanya gusaza, kubungabungwa no kubungabunga ibidukikije, kandi byakoreshejwe cyane mumirongo ya 35kV na 110kV.
