Bushing: momo me momo

Ka whakarato tēnei tuhinga mōhiohio e pā ana ki te bushings, ratou ia ahua, me te momo. Ka kia wahia taipitopito hanganga o ngā momo, momo ratou, ratou hōkai me te whakaaro. Ka hoki te whakaaro te reira i to ratou painga i roto i te rite ki te pūrere rite. I muri te tai'oraa i te tuhinga, koe ako kore anake ngā mōhiohio whānui e pā ana ki te bushings, engari ano hoki e taea ki te kīa te tapanga me te kia taea ki te wehewehe tetahi momo i tetahi.

Scope o nga bushings

He aha te mea bushing? Ko te pūrere motuhake, te mahi matua o te mea ki te whakarite wehe o ngā āhuatanga conductive o te taiepa i roto i waho ranei o te takotoranga i roto i nei ratou haere tenei. Ratou ano e whakamahia i roto i te tāutanga o ngā pūrere tohatoha o teihanaroto hiko, te tākaro hoki i te wāhi i roto i te kitenga pokapū whakawhitinga Complete.

E hangaia insulators Tautoko mō te whakatika rārangi rauata ki busbars ora switchgear me ētahi atu ngā utanga hiko. Ko reira utu tāpiri e te momo insulators porcelain i rongonui i mua, whakamahia ki tenei ra ki te rota o akatuke'anga.

He tino watea ki te whakamahi i mo te teihanaroto terminals hononga, i nei powered kāinga nga bushings.

momo o insulators

E wehea Bushings ki e rua momo. Ko te momo tuatahi - ko insulators, e kua hangaia mō te tāutanga roto. E whakamahia ratou rite tiketike-mārua tiketike-ngaohiko terminals taiawhio o te transformers ranei. hanga Bushing puka tuku te o porcelain, ka kei te hua e roto i te tokotoko whakarewa. Kei te whakaritea te reira e te tikanga o karapiti i hanga o whakarewa, he pōtae porcelain piri me te hanganga onepu tāpiapia.

Ko te momo tuarua hurihia hoki te waho, me te mo te tāutanga roto. E hanga taua whakaaro rara takawaenga e kua whakaritea i te tawhiti iti i ia atu. E hangaia ēnei whakaaro mō te mātao i nga wahi ora karapoti switchgear. whakamahia te bushing o tenei momo te i te whatunga ngaohiko whakahaere 10, 25, 35, 110 kV, me te nāianei whakahaere o i 630 ki te 11,000 A.

He hoki atu momo o insulators, engari kua hangaia e ratou mo te tono ūnga motuhake. E hiahiatia ana ngā pūrere momo rere hoki mātao switchgear wahi conductive mō te hononga o te kiritaki ki te tupare rārangi rangi tuku. whakaarahia e hanga i ngā rauemi enei hua te pa ki to ratou hoahoa he ātete ki kawenga o nāianei hihiri.

painga o insulators

kia whai i te ora roa te bushing, na te mea i te āhuatanga e whai ake nei:

• ātete tiketike ki tikanga whakahaere kaitaua;
• he taimaha āhua iti;
• UV resistance;
• kaha nui;
• ora ratonga roa;
• āhuatanga āhua iti.

hoahoa IP

Me riro Bushings SP tino kaha mīhini, me te hiko, Heoi te rauemi e hanga e ratou i ai, kia rite ki whai:

• waerau;
• porcelain;
• karaihe i konatunatua.

Kei te hangaia te insulator ki raru ngaohiko i teitei īnaki ngaohiko. E tonu isolators waho i raro i te mana o ngā āhuatanga taiao waho, na anchor ratou mata te. meatia ana tēnei te āta ki te whakapai ake i te mahi o te hua.

Insulators opua ia wehewehea ki bushing, tautoko ranei whakatārewatanga, i reira e ano tikanga o tāutanga mo türanga i roto i ngā whare, me ngā hanganga mō te tāutanga waho ranei.

Haere SP-10 te tino maha hanga i porcelain. whakaritea te whakatinanatanga whai hua o te insulator taua te i te ngaohiko te tauanga me te auau o te mana arumoni. Ko te pūrere ngā iho o te tinana porcelain o āhua porotakaroa, eke i runga i kakau e taha piri herea ia te whakamahi i te paru pokepoke sima-onepu.

bushings Wāhui

Ko te whakaaro matua o te bushings ko ki tutakina te conductors ora, e haere i roto i nga taiepa, me te hipoki o whare hanganga ranei. E tito taua insulators o te porcelain uruhanga. hanga te tinana i roto i te puka o te rango, i runga i te tihi o e reira ko te tokotoko o nāianei-mau ana. I te toharite, eke te taumata o te whare whakarewa karapiti i, rite whakahuatia i mua, te tikanga ki te kia whakaritea ki te mata insulator.

hanga SP Bushing i te ngaohiko whakahaere ki te 10 kV te o porcelain, ka hanga i te ngaohiko whakahaere rawa 35 kV ko te whare rite te hanganga mātao matatini e, i roto i te tahuri, ngā o te porcelain tinana, papa paraharaha, pepamārō, pepa tuuraa i me te hinu hiko.

whakapuru bushings

A, no te whakapuru bushings waho tirotirohia hoki kapiti, me te tahi atu mea kohakore, rite ai kia pakaru i roto i te mata waka o insulators. titiro hoki ahakoa kua tawhitotia atu te pīata mata, e whakamahia nei mō ngā hua tiaki me te mātao tāpiri.

kia whakanohoia insulators i runga i tetahi hanganga whakarewa ki te mau i te hua, me te te mauroa o potae waea hiko pou ranei.

Tāuta bushings tīmata ki te whakatakoto i te paraharaha tomokanga, piri nei ki te hanganga i tetahi kēmu ranei. I tua atu, katia nga insulators kei i runga i ngā taha e rua e potae ki pātaki rino whakarewa he tatau tapawhā Ahakoa tereina tereina. tei to ratou rahi i runga i te rahi o te mauiui, me te tāhu. I runga i nga whakatau o te tuhinga i waenganui i te tupare whakaritea rauawa eke potae.

tohu bushings

Tohu hurihia i roto i te tikanga ki te whakanui i nga āhuatanga katoa o te hua. Hei tauira, te insulator irava SP-10 630 7.5 UHL1, ai:

• A - he insulator;
• P - haere;
• 10 - te ngaohiko whakahaere noa o te hua (kV);
• 630 - ko te hua noa whakahaere nāianei (A);
• 7.5 - whawhati kawenga (KN);
• UHL - ngā takiwā makariri o te mahi;
• 1 - te kāwai o te noho.

Rärangi ngaohiko o PI

kia rerekē rärangi ngaohiko SP porcelain i runga i te matotoru o te apa porcelain rānei. Ahakoa tenei, i whakaritea te hanganga insulator e te kaha mīhini hiahiatia, tauanga ngaohiko o mehua inaki, me atu mo te tango o te karauna.

A, no te kore e tango i te bushing 10 kV mehua ki te tango i te kurahauao. Ki te kei te whakamahia ngaohiko iti i runga 35 kV mō mehua tāutanga tata te karauna o te tokotoko ritenga te flange, tika i te wāhi i reira mānukanuka mōrahi i roto i te rangi.

Hei ārai i kurahauao, hangaia insulators kahore kōhao rangi huri noa te tokotoko whakarewa tikanga i roto i te insulator. I roto i tenei SP mata metallized ki te rakau. I roto i te tikanga ki te whakakore i te takanga o te rere i te SP raro, ano i raro metallized mata, me te ake tangata whenua.

mutunga

Pea kua ake kite katoa rārangi rererangi hiko e e piri ki te SP. E hiahiatia ana hoki enei whakaaro mo te hononga o nga waea ki te tāuta whakaritea, no te mea kahore insulators hononga taea o waea tiketike-ngaohiko.
