Ama-insulatorsizilawuli ezikhethekile zokuxhuma ezingadlala indima ebalulekile emigqeni yokudlulisela phezulu.Eminyakeni yokuqala, ama-insulators ayesetshenziswa kakhulu ezigxotsheni zensiza, futhi kancane kancane athuthukiswa abe imibhoshongo yokuxhumana yezintambo ezinamandla amakhulu lapho ama-insulators amaningi amise okwe-disc ayelengiswa ekugcineni.Yayisetshenziselwa ukwandisa ibanga le-creepage, ngokuvamile eyenziwe ngengilazi noma izitsha zobumba, futhi yayibizwa ngokuthi i-insulator.Ama-insulators adlala izindima ezimbili eziyisisekelo emigqeni yokudlulisela phezulu, okuyizintambo ezisekelayo nokuvimbela umbane ukuthi ungabuyeli phansi.Le misebenzi emibili kufanele iqinisekiswe.Ama-insulators akufanele ahluleke ngenxa yokucindezeleka okuhlukahlukene kwe-electromechanical okubangelwa izinguquko endaweni kanye nezimo zomthwalo kagesi.Uma kungenjalo, i-insulator ngeke idlale indima ebalulekile, futhi izolimaza impilo yesevisi nempilo yokusebenza yawo wonke umugqa.
I-insulator: Kuyinto elungisa futhi imise ucingo embhoshongweni ngendlela evalekile.Ama-insulators asetshenziswa kakhulu emigqeni yokudlulisa amandla yilezi: ama-porcelain insulators amise okwe-disc, ama-insulators engilazi amise okwe-disc,
Ukumiswa kwendukuama-insulators ahlanganisiwe.(1) Izivikeli zebhodlela le-porcelain: izivikeli zobumba ezifuywayo zinezinga eliphezulu lokuwohloka, zidinga ukuthola amanani aziro, futhi zibe nomsebenzi omkhulu wokuzilungisa.
Uma kwenzeka kushaywa umbani nokugqashuka kokungcola, izingozi zokwehla kwezintambo zivame ukwenzeka, futhi ziye zaqedwa kancane kancane.(2) Isivikeli sengilazi: Inoziro oziqhumayo, kodwa izinga lokuziqhumisa liphansi kakhulu (ngokuvamile liyinkulungwane eziyishumi ezimbalwa).Akukho ukuhlolwa okudingekayo ukuze kulungiswe.Uma kwenzeka ukuziqhuma kwezingxenye zengilazi ezithambile, amandla asele emishini asazofinyelela ngaphezu kwe-80% yamandla okuphuka, asengaqinisekisa ukusebenza okuphephile komugqa.Ngeke kube nezingozi ezilandelanayo zokwehla uma kwenzeka kushaywa umbani kanye nokuqubuka kokungcola.Isetshenziswe kakhulu ezindaweni ezingcolile ze-Class I kanye ne-Class II.(3) Isivikeli esihlanganisiwe: Inezinzuzo zokusebenza okuhle kwe-flashover ephikisana nokungcola, isisindo esilula, amandla aphezulu emishini, nokugcinwa okuncane, futhi isetshenziswe kabanzi ezindaweni ezingcolile zeleveli III nangaphezulu.
Ama-insulators e-porcelain: Ama-insulators aziwa kakhulu ngokuthi amabhodlela e-porcelain, okungama-insulators asetshenziselwa ukusekela izintambo.Ama-insulators angaqinisekisa ukufakwa okwanele kwamakhondakta, izingalo eziphambanayo nemibhoshongo.Kufanele ikwazi ukumelana nomthwalo ohlangothini oluqondile lwentambo kanye nokungezwani endaweni evundlile ngesikhathi sokusebenza.Iphinde imelane nelanga, imvula, ukushintsha kwesimo sezulu kanye nokugqwala kwamakhemikhali.Ngakho-ke, ama-insulators kufanele abe nezinto ezinhle zikagesi namandla anele okusebenza.Izinga le-insulator libaluleke kakhulu ekusebenzeni okuphephile komugqa.Ama-insulators angahlukaniswa abe ama-insulators asekelayo, ama-insulators amisiwe, ama-anti-pollution insulators kanye nama-insulators angama-bushing ngokusho kwesakhiwo sawo.Ngokwenhloso, ingahlukaniswa ngokujwayelekile izigaba ezintathu: ama-insulators emigqa, ama-insulators asekela iziteshi ezingaphansi kanye nama-bushings.Ngokusho kwempahla ye-insulator.Njengamanje kukhona ama-porcelain, ingilazi nama-organic composite insulators.Ama-insulators asetshenziswa emigqeni engaphezulu ama-pin insulators, ama-butterfly insulators, ama-suspension insulators, i-porcelain cross-arms, i-rod insulators kanye ne-tension insulators.Kunezinhlobo ezimbili zamaphutha kagesi kuma-insulators: i-flashover kanye nokuphuka.I-Flashover yenzeka ebusweni be-insulator, futhi izimpawu zokusha zingabonakala, kodwa ngokuvamile ukusebenza kwe-insulator akulahleki;ukuphuka kwenzeka ngaphakathi kwe-insulator, futhi ukukhishwa kwenzeka emzimbeni we-ceramic phakathi kwekepisi lensimbi nonyawo lwensimbi.Ama-insulators angabhujiswa ngokuphelele ngama-arcing.Ukuze kube nokuqhekeka, ukunakwa kufanele kukhokhwe ekuhloleni iminonjana yokukhishwa nokusha kwezinyawo zensimbi.Ukuze kuvinjwe ukungcola okunjengothuli oluntantayo ukuthi lunganamatheli endaweni yesivikelo, kwakhiwa indlela ephulwa amandla kagesi emikhawulweni yomibili yesivikelo, okungukuthi, i-creepage.Ngakho-ke, ibanga elingaphezulu liyakhuphuka, okungukuthi, ibanga le-creepage, kanye nebanga elikhishwa eduze kwendawo yokushisa, okungukuthi, ibanga lokuvuza, libizwa ngokuthi ibanga le-creepage.
Ibanga le-Creepage=ibanga elingaphezulu/amandla kagesi aphezulu wohlelo.Ngokwezinga lokunukubezeka, ibanga le-creepage livamise ukuba ngu-31 mm/ikhilovolthi ngayinye ezindaweni ezingcoliswe kakhulu.Amandla kagesi angahlulelwa ngokuqondile ngokwenani lama-insulators, ngokuvamile, angu-23 ku-500kv;16 ku-330kv;220kv 9;110kv 5;leli inani elincane, futhi kuzoba khona oyedwa noma ababili ngaphezulu.Ilayini ka-500kv kagesi isebenzisa amakhondatha ahlukene kane, okusho ukuthi, kukhona ezine esigabeni esisodwa, u-220kv usebenzisa amakhondatha ahlukene amabili, kanti i-110kv isebenzisa esinye futhi.Mayelana 1 insulator kuyinto 6-10KV, 3 insulators kukhona 35KV, 60KV imigqa awekho ngaphansi 5 izingcezu, 7 insulators kukhona 110KV, 11 insulators kukhona 220KV, 16 insulators kukhona 330KV;Ama-insulators angama-28 ngokuqinisekile angu-500KV.Kuma-pin insulators angaphansi kuka-35KV, awukho umehluko enanini lezingcezu.Imigqa engaphezulu engu-10KV ivamise ukusebenzisa izigxobo zikasimende eziwu-10-12m kanye nezivikeli zamaphini.Ibanga lomugqa oqondile phakathi kwezigxobo lingaba ngu-70-80m.Alukho uhlaka lwensimbi lwe-10KV, isigxobo nje esinemigqa emithathu yamandla aphezulu kuso.Okujwayelekile ezindaweni zasemakhaya;Imigqa engu-35KV engaphezulu ivamise ukusebenzisa izigxobo zikasimende ezingamamitha ayi-15 eyodwa noma ezimbili (futhi sebenzisa inani elincane lemibhoshongo yensimbi encane, ukuphakama kungaphakathi kwamamitha ayi-15-20) kanye nezingcezu ezi-2-3 zama-butterfly insulators, umugqa oqondile phakathi kwezigxobo. cishe amamitha angu-120;I-220KV ingumbhoshongo omkhulu wensimbi.Imigqa engaphezulu engu-220KV ivamise ukusebenzisa imibhoshongo yensimbi engaphezu kwamamitha angu-30 nezintambo ezinde zezivikeli zemvemvane.Ibanga lomugqa oqondile phakathi kwemibhoshongo yensimbi lingaphezu kwamamitha angama-200.Ama-insulators ahlanganisiwe: Ukuqinisekisa ukusebenza okuphephile kwesistimu yamandla kanye nokwenza ngcono ukuthembeka kokunikezwa kwamandla kuyinkomba ebalulekile yokuhlolwa kwezinkampani zamandla, futhi ukusetshenziswa okuqhubekayo kwezinto zobuchwepheshe obuphezulu kuyindlela ephumelelayo yokuxazulula le nkinga.Njengomkhiqizo omusha, isivikeli esihlanganisiwe senjoloba ye-silicone sinezinzuzo zesisindo esilula, usayizi omncane, i-anti-flashover, ukumelana nokuguga, ukunganakeki nokugcinwa, futhi isetshenziswe kakhulu emigqeni engu-35kV kanye ne-110kV.
