Insulatorsndiwo akakosha ekudzivirira ekudzivirira anogona kuita basa rakakosha mumitsara yekutapurirana pamusoro.Mumakore ekutanga, insulators yainyanya kushandiswa pamatanda ekushandisa, uye zvishoma nezvishoma yakagadziridzwa kuita yakakwirira-voltage waya yekubatanidza shongwe uko akawanda madhisiki-akaumbwa insulators akaturikwa kune imwe mugumo.Yaishandiswa kuwedzera kureba kwecreepage, kazhinji yakagadzirwa negirazi kana ceramics, uye yainzi insulator.MaInsulators anotamba mabasa maviri ekutanga mumitsara yekutapurirana pamusoro, kureva waya dzekutsigira uye kudzivirira ikozvino kuti isadzokere pasi.Aya mabasa maviri anofanira kuvimbiswa.Insulators haifanirwe kukundikana nekuda kweakasiyana electromechanical kusagadzikana kunokonzerwa nekuchinja kwezvakatipoteredza uye magetsi mutoro mamiriro.Zvikasadaro, iyo insulator haizoite basa rakakosha, uye inokuvadza hupenyu hwesevhisi uye hupenyu hwekushanda hwemutsara wese.
Insulator: Chinhu chinogadzirisa nekumisa waya pashongwe nenzira inodzivirira.Inowanzo shandiswa insulators yemagetsi ekufambisa mitsara ndeiyi: disc-shaped porcelain insulators, disc-shaped glass insulators,
Kumiswa kwetsvimbocomposite insulators.(1) Porcelain bhodhoro insulators: mudzimba porcelain insulators ane mwero wakanyanya kuderera, anoda kuona zero kukosha, uye ane yakakura basa rekugadzirisa.
Muchiitiko chekurova kwemheni uye kupenya kwekusvibisa, njodzi dzekudonha kwetambo dzinowanzo kuitika, uye dzakapedzwa zvishoma nezvishoma.(2) Girazi insulator: Iine zero self-explosion, asi mwero wekuzviputika wakadzikira (kazhinji mashoma gumi ezviuru).Hapana kuongorora kunodiwa pakugadzirisa.Muchiitiko chekuzviputira kwezvikamu zvegirazi dzakadzikama, iyo yakasara yemagetsi simba icharamba ichisvika kupfuura 80% yesimba rekupwanya, iro rinogona kuchengetedza kushanda kwakachengeteka kwemutsara.Pachave pasina tsaona dzekudonha kana kurohwa nemheni uye kusvibiswa kwemhepo.Yakave ichishandiswa zvakanyanya muKirasi I uye Kirasi II nzvimbo dzekusvibisa.(3) Composite insulator: Iine zvakanakira yeakanaka anti-kusvibiswa flashover performance, huremu huremu, high mechanical simba, uye kushomeka kwekugadzirisa, uye yakashandiswa zvakanyanya munzvimbo dzakasvibiswa dzenhanho III uye pamusoro.
Porcelain insulators: Insulators inowanzozivikanwa semabhodhoro eporcelain, ayo ari insulators anoshandiswa kutsigira waya.Insulators inogona kuve nechokwadi chekuvharira kwakaringana kwemakondakita, kuyambuka maoko uye shongwe.Inofanira kukwanisa kumira mutoro munzira yakatwasuka yewaya uye tension munzira yakatwasuka panguva yekushanda.Inoshingirira zvakare kuzuva, mvura, kushanduka kwemamiriro ekunze uye kuora kwemakemikari.Naizvozvo, ma insulators anofanirwa kunge aine zvese zvakanaka zvemagetsi zvivakwa uye yakakwana yemagetsi simba.Hunhu hweiyo insulator hwakakosha kwazvo pakushanda kwakachengeteka kwemutsara.Insulators inogona kukamurwa kuita insulators inotsigira, kuturika insulators, anti-kusvibisa insulators uye bushing insulators zvinoenderana nechimiro chavo.Zvinoenderana nechinangwa, inogona kuganhurwa muzvikamu zvitatu: mitsara insulators, substation inotsigira insulators uye bushings.Maererano nezvinhu zve insulator.Parizvino kune porcelain, girazi uye organic composite insulators.Iyo insulators inoshandiswa mumitsetse yekumusoro inowanzoshandiswa pini insulators, butterfly insulators, suspension insulators, porcelain cross-arms, rod insulators uye tension insulators.Kune marudzi maviri ekukanganisa kwemagetsi mune insulators: flashover uye kuparara.Flashover inoitika pamusoro peiyo insulator, uye zviratidzo zvinopisa zvinogona kuonekwa, asi kazhinji kushandiswa kwekudzivirira hakusi kurasikirwa;kuparara kunoitika mukati me insulator, uye kubuda kunoitika kuburikidza nemuviri weceramic pakati pekapu yesimbi uye tsoka yesimbi.Insulators inogona kuparadzwa zvachose ne arcing.Nokuda kwekuputsika, kutarisirwa kunofanira kubhadharwa pakuongorora maitiro ekubuda uye kupisa kwemakumbo esimbi.Kuti udzivise tsvina yakaita seguruva rinoyangarara kubva kunamira kumusoro kwechidziviriro, nzira inoumbwa inoputswa nevoltage kumativi ese echidziviriro, ndiko kuti, creepage.Naizvozvo, kureba kwepamusoro kunowedzerwa, ndiko kuti, chinhambwe chinokambaira, uye chinhambwe chinoburitswa padivi penzvimbo inodzivirira, ndiko kuti, kureba kwekudonha, kunonzi creepage kureba.
Creepage kureba = kureba kwepamusoro / yakakura voltage yehurongwa.Zvinoenderana nedhigirii rekusvibiswa, chinhambwe chinokambaira chinowanzoita 31 mm/pa kilovolti munzvimbo dzakasvibiswa zvakanyanya.Iyo voltage inogona kutongwa zvakananga zvichienderana nehuwandu hwema insulators, kazhinji, 23 ye500kv;16 ye330kv;220kv 9;110kv 5;iyi ndiyo nhamba shoma, uye pachava nemumwe kana maviri mamwe.Iyo 500kv transmission line inonyanya kushandisa mana-split conductors, kureva kuti, pane ina pachikamu chimwe, 220kv inoshandisa anopfuura maviri akapatsanura conductor, uye 110kv inoshandisa imwezve.Inenge 1 insulator ndeye 6-10KV, 3 insulators ndeye 35KV, 60KV mitsetse haisi pasi pe5 zvidimbu, 7 insulators ndeye 110KV, 11 insulators ndeye 220KV, 16 insulators ndeye 330KV;28 insulators zvechokwadi 500KV.Kune mapini insulators pazasi 35KV, hapana mutsauko muhuwandu hwezvidimbu.10KV mitsetse yekumusoro inowanzo shandisa 10-12m single simende mapango uye mapini insulators.Iyo yakatwasuka-mutsara kureba pakati pematanda inenge 70-80m.Iko hakuna simbi furemu ye10KV, ingori danda rine mitsetse mitatu yakakwira-voltage pairi.Inowanikwa kumaruwa;35KV pamusoro pemitsetse inowanzoshandisa 15-mita imwe chete kana kaviri simende matanda (uyewo shandisa diki diki shongwe dzesimbi, kureba kuri mukati me15-20 metres) uye 2-3 zvidimbu zve butterfly insulators, mutsara wakatwasuka pakati pematanda Chinhambwe chiri anenge 120 metres;220KV zvirokwazvo ishongwe huru yesimbi.220KV mitsetse yekumusoro inowanzo shandisa shongwe dzesimbi dzinopfuura 30 metres uye tambo refu dze butterfly insulators.Iyo yakatwasuka-mutsara kureba pakati pesimbi shongwe inopfuura 200 metres.Composite insulators: Kuve nechokwadi chekushanda kwakachengeteka kwesimba remagetsi uye kuvandudza kuvimbika kwemagetsi emagetsi chiratidzo chakakosha chekuongorora kwemakambani emagetsi, uye kuenderera mberi kwekushandiswa kwezvinhu zvepamusoro-tech inzira inoshanda yekugadzirisa dambudziko iri.Sechigadzirwa chitsva, silicone rubber composite insulator ine zvakanakira uremu huremu, saizi diki, anti-flashover, kuchembera kuramba, kuchengetedza-isina uye kuchengetedza-isina, uye yakashandiswa zvakanyanya mumitsara ye35kV uye 110kV.
