Akwa voltaji ahịrị diski nkwusioru poselin insulators na-ekewa n'ime ụdị nkịtị na ụdị na-eguzogide mmetọ.A na-eji ya maka ahịrị nnyefe voltaji dị elu na ultra-high voltaji iji kwụsịtụ ma ọ bụ ndị na-eduzi esemokwu ma kpochie ha n'osisi na ụlọ elu.Ihe mkpuchi nkwusioru nwere nnukwu igwe na ike eletrik.Enwere ike itinye ha na ọkwa voltaji dị iche iche site na otu eriri dị iche iche ma gboo mkpa ike dị iche iche.Ọ bụ ha kacha eji eme ihe.Ụdị nkịtị kwesịrị ekwesị maka mpaghara mmepụta ihe n'ozuzu.E jiri ya tụnyere insulators nkịtị, ndị na-egbochi mmetọ mmetọ nwere ogologo creepage na ọdịdị dị mma maka nhicha ikuku na mmiri ozuzo.Ha dabara maka oke osimiri, ntụ ntụ ọla, mmetọ kemịkalụ na mpaghara mmetọ ụlọ ọrụ ka njọ.Mgbe a na-eji ihe mkpuchi na-eguzogide mmetọ na mpaghara ndị dị n'elu, ọ nwere ike ibelata ụlọ elu ahụ ma nwee nnukwu uru akụ na ụba.

Ebumnobi nke elu voltaji ahịrị diski nkwusioru iko insulator bụ isi bụ otu ihe ahụ nke elu voltaji ahịrị diski nkwusioru poselin insulator.Igwe mkpuchi iko nwere njiri mara nke ike igwe dị elu, nguzogide mmetụta igwe, ezigbo oyi na arụ ọrụ ọkụ, ogologo ndụ ọrụ, arụmọrụ eletriki dị mma na nguzogide ọkụ.Mgbe ọ mebiri emebi n'oge ọrụ, diski nche anwụ ya ga-agbaji na-akpaghị aka, nke dị mfe ịchọta, na-ebelata oke ọrụ nke nchọpụta mkpuchi.

A na-eji insulator dị elu ahịrị ahịrị elu voltaji na-eme ihe na ọdụ njedebe, ogwe aka mgbakasị na ogwe nkuku nke ahịrị ike dị n'obere ya na obere onye na-eduzi cross-ngalaba nke l0kV na n'okpuru dị ka mkpuchi na onye na-edozi ihe.Ọ nwere ike dochie ụfọdụ insulators poselin nru ububa na nkwusioru diski poselin insulators.

③ Mgbochi ụdị ihe mkpuchi mkpuchi maka sistemu kọntaktị n'elu nke okporo ụzọ ụgbọ oloko eletrik.

2. Insulator ahịrị ahịrị dị ala

① Ụdị pin, ụdị nru ububa na spool ụdị mkpuchi mkpuchi maka ahịrị obere voltaji: a na-eji ihe mkpuchi mkpuchi na-edozi ndị na-eduzi n'elu ahịrị ike dị n'okpuru 1KV.A na-eji insulators na spool poselin insulators na spool poselin insulators maka ahịrị obere voltaji dị ka ndị na-eduzi mkpuchi na nke edobere na ọdụ ọkụ na nkesa ahịrị, esemokwu na mkpanaka akụkụ.

② Tension poselin insulator maka n'elu ahịrị: ọ na-eji maka itule esemokwu nke okporo osisi na ọnụ nke AC na DC n'elu nkesa ahịrị na nkwurịta okwu ahịrị, nkuku ma ọ bụ ogologo span okporo osisi, nke mere ka ikpuchi ala ọnụnọ waya si elu. nọrọ waya.

③ Insulator maka ahịrị tram: ejiri ya dị ka ihe mkpuchi na onye na-eme mkpọtụ maka ahịrị tram ma ọ bụ ihe mkpuchi na nkwado maka akụkụ na-eduzi na tram na ọdụ ike.

④ Pin ụdị ihe mkpuchi mkpuchi maka ahịrị nkwurịta okwu: ejiri maka mkpuchi na idozi onye na-eduzi n'ahịrị nkwurịta okwu n'elu.

⑤ Insulators maka wiring: gụnyere insulators drum, poselin splints na poselin tubes, nke a na-eji maka obere voltaji wiring.

3. High voltaji ike ọdụ insulator

① High voltaji ime ụlọ post insulator maka ike ọdụ: ọ na-eji na eletriki akụrụngwa ụgbọ ala na nkesa ngwaọrụ nke ime ụlọ ọdụ ụgbọ na substation na ike ugboro gosiri voltaji nke 6 ~ 35kV.Dị ka ihe mkpuchi mkpuchi maka akụkụ conductive voltaji dị elu.A na-etinyekarị ya n'ogo nke na-erughị 1000m na ​​ọnọdụ okpomọkụ dị - 40 ~ 40 ℃, ekwesịrị iji ya na-enweghị mmetọ na condensation.Enwere ike iji ụdị ala dị larịị ahaziri ahazi na mpaghara nwere elu 3000m na ​​5000m.

② n'èzí pin post insulator: ọ bụ ọdabara na a gwara mmanụ akụkụ nke eletriki ngwa ma ọ bụ ike nkesa ngwaọrụ na AC gosiri voltaji nke 3 ~ 220kV, ambient okpomọkụ nke - 40 ~ + 40 ℃ gburugburu echichi saịtị na elu nke ọ dịghị ihe karịrị 1000m.A na-eji ya dị ka ihe mkpuchi na onye nduzi edozi.

③ Oghere mkpanaka post insulator: a na-eji ya maka ngwa eletriki eletrik dị elu na ngwaọrụ nkesa voltaji dị elu iji kpuchie ma dozie ndị na-eduzi.Ọ dochiela n'ụzọ dị ukwuu iji insulators post n'èzí.

④ Antifouling n'èzí mkpanaka post insulator: adabara njupụta mkpuchi nnu nke 0.1mg / cm ² A na-eji mpaghara mmetọ nke ọkara n'ime maka mkpuchi na ndozi nke ngwa eletriki eletrik dị elu na ngwaọrụ nkesa ike.
