Bushing:-daban da kuma irin

Wannan labarin zai samar da bayanai game da bushings, irinsu da kuma iri. Details za a rushe tsarin da daban-daban iri, iri da kansu, su ikon yinsa, da kuma manufa. Shi kuma za a yi la'akari da su da abũbuwan amfãni a kwatanta da irin wannan na'urorin. Bayan karanta labarin, za ka ba kawai koyi janar bayanai game da bushings, amma kuma su iya decipher da tasirin da kuma iya rarrabe daya jinsin daga wani.

Bigiren da bushings

Mene ne bushing? Wannan shi ne na musamman na'urar, babban aiki na wanda shi ne ya tabbatar da kadaici da conductive abubuwa na ciki ko na waje bango na daina kai hare hare ta hanyar abin da suka wuce. Su ma suna amfani da shigarwa na rarraba na'urorin na gidan wuta substations, kuma taka rawa a cikin binciken Complete sharuddan sauyawa cibiyoyin.

Support insulators aka tsara don kayyade sama Lines tare da live busbars switchgear da sauran lantarki shigarwa. Yana da daraja kara da cewa ain insulators irin da suke rare kafin, amfani da wannan rana tare da wani yawa na gyare-gyare.

A bushings ne sosai dace don amfani ga connection tashoshi substations, daga abin da powered gidajensu.

irin insulators

Bushings ya kasu kashi biyu iri daban-daban. Nau'i na farko - shi ne insulators, wanda aka tsara domin na cikin gida da kafuwa. Suna amfani da high-wuri ko high-ƙarfin lantarki kewaye tashoshi na gidajen wuta. Bushing ƙaddamar fom da aka yi da ain, da samfurin da aka located cikin wani karfe sanda. Yana yana gyarawa ta hanyar flanges sanya daga karfe, ain hula a haɗe da m yashi abun da ke ciki.

Nau'i na biyu reassigned ga m da kuma ga ciki da kafuwa. Irin wannan na'urorin an halitta matsakaici hakarkarinsa cewa ana shirya a kananan nesa daga juna. Wadannan na'urori ana tsara don rufi daga live sassa kewaye switchgear. A bushing na irin wannan da ake amfani a wani aiki irin ƙarfin lantarki sadarwa 10, 25, 35, 110 KV, da kuma aiki halin yanzu na daga 630 zuwa 11,000 A.

Akwai kuma sauran iri insulators, amma suna tsara don wani takamaiman manufa aikace-aikace. kwarara da irin na'urorin da ake bukata domin rufi switchgear conductive sassa for dangane da masu amfani da su da taya iska watsa Lines. Wadannan kayayyakin an sanya daga kayan tãyar da sansanin soja zuwa da zane ne resistant zuwa tsauri halin yanzu lodi.

abũbuwan amfãni daga insulators

A bushing kamata yi tsawon rai, don haka shi yana da wadannan halaye:

• high jure m aiki yanayi;
• mun gwada da kananan nauyi.
• UV juriya.
• high ƙarfi.
• dogon sabis rayuwa;
• gwada da kananan girma.

zane IP

Bushings SP dole mallaka matsananci inji da lantarki ƙarfi, duk da haka abu daga wanda aka sanya, yana iya zama kamar haka:

• polymer.
• ain.
• zafin gilashi.

A insulator da aka tsara don rashin lafiya irin ƙarfin lantarki da aka fi ƙarfin lantarki zoba. External isolators ne kullum a ƙarƙashin rinjayar waje muhalli dalilai, don haka su surface ne grooved. Wannan ne yake aikata musamman don inganta aiki na samfur.

Insulators nufi subdivided cikin bushing, support ko dakatar, akwai kuma hanyoyin da kafuwa for jeri a cikin gine-gine da kuma Tsarin ko ga waje da kafuwa.

Wucewa SP-10 da aka fi sau da yawa sanya daga ain. A sanyata aiwatar da irin wannan wani insulator aka ƙaddara daga rated ƙarfin lantarki da kuma mita na kasuwanci iko. Da na'urar da kanta kunshi wani ain jiki na cylindrical siffar, saka a kan axles wanda gefuna tam bonded yin amfani da ciminti-yashi turmi.

ganawa bushings

Babban manufar da bushings ne don ware da live conductors, wanda wuce ta cikin ganuwar da sutura na gine-gine ko Tsarin. Irin wannan insulators an hada da wani dielectric ain. The jiki da aka yi a cikin wani nau'i na Silinda, a saman abin da akwai halin yanzu-dauke da sanda. A kan talakawan, da matakin na karfe gidaje saka flanges wanda, kamar yadda aka ambata a baya, za a yi nufin gyarawa zuwa insulator surface.

Bushing SP a wani aiki irin ƙarfin lantarki zuwa 10 KV aka sanya na ain, kuma a wani aiki irin ƙarfin lantarki wucewa 35 KV da gidaje da aka yi a matsayin wani hadadden rufi Gininsu, wanda, bi da bi, ƙunshi jiki ain, kwali faranti, insulating takarda da gidan wuta man fetur.

hawa bushings

Lokacin da hawa bushings waje binciki for fasa da sauran lahani, kamar yadda a iya lalace a lokacin kai surface na insulators. Har ila yau, bincika ko surface glaze ya sawa kashe, wanda ake amfani da kara kariya da kuma rufi kayayyakin.

Insulators ya kamata a sanya a kan wani karfe Tsarin zuwa amince da samfurin, kazalika da karko na tayoyin ko sama ikon Lines.

Girkawa bushings fara da ajiye ƙofar farantin, wanda aka haɗe da tsarin ko duk wani tsayarwa. Bugu da ari, insulators aka rufe a garesu da iyakoki da baƙin ƙarfe karfe partitions da ciwon rectangular takware kama jirgin dogo. Su size ya dogara da girman da hula da kuma kulla. A cikin karshe da labarin tsakanin hula gyarawa saka struts tayoyin.

Sa alama bushings

Sa alama reassigned domin haskaka dukan siffofin da samfurin. Alal misali, insulator nassi SP-10 630 7.5 UHL1, a cikinsa:

• Kuma - wani insulator.
• P - wuce.

• UHL - yanayin damina da kisa.
• 1 - category na masauki.

Fashewa ƙarfin lantarki na PI

Fashewa ƙarfin lantarki ain SP iya zama daban-daban dangane da kauri daga cikin ain Layer. Duk da wannan, da insulator tsarin ne m da ake bukata inji ƙarfi, rated ƙarfin lantarki na overlapping da kuma ƙarin matakan ga kau da kambi.

Lokacin da bushing 10 KV ba su dauki matakai don cire Corona. Tare da maras muhimmanci voltages sama 35 KV ana amfani da matakan da kafuwa kusa da kambi na sanda daura da flange, kawai a aya inda matsakaicin tashin hankali a cikin iska.

Don hana Corona, insulators kerarre ba tare da iska rami a kusa da karfe sanda zubar cikin insulator. A wannan metallized surface SP tare da sanda. Domin kawar da ya faru na sallama a kasa SP, kuma a ƙasa surface metallized da kuma kara na rasa.
