Bushing: ano a me keia ano

He 'atikala e hoʻolako' ike e pili ana i na bushings, kā lākou mauʻano a me ka ano. Details e e wāwahi 'ole o nāʻano likeʻole, ano ia lakou iho, i ko lakou laulā a me ka manao. It E e noonoo i ko lakou mau pono e like me ka like manaʻo. e heluhelu ana i ka 'atikala ma hope, e ole wale aʻo mau' ike e pili ana i na bushings, akā, no hoi e hiki ke decipher i ka lepili, a e hiki ke hoomaopopo i kekahi? ueo mai kekahi.

Laulā o ka bushings

He aha ka bushing? He He kūikawā mea, i ka papa kuhikuhi hana o ka i mea e hōʻoia 'hoʻokaʻawale o ka lawelawe oihana mua o ka pā a mawaho paia o ka wahi ma a lakou i hele aku. Ua hoʻohana 'ia i loko o ka mea hoʻonoho o ka haawi aku i na mea maalea o ka mea hoʻololi uila substations, i pāʻani i ke kūlana i loko o nā kūʻiʻoa pono'ī ka hoʻololiʻana-oaio? A.

Kākoʻo insulators i papahana no ka hoʻopunipuni lolo laina me ka noho busbars switchgear a me nā pou nā mea hoʻonoho. He waiwai ohui i ka porcelain insulators 'ano i ka poe kaulana ma mua, hoʻohana' ia i kēia lā me ka hailona no ka hoʻololi 'ana.

Nā bushings i nui kupono e hana ai no ka pilina maʻi substations, mai i mana home.

ano o insulators

Bushings i maheleia i mau ano. Ka muaʻano - ka insulators, a i papahana no ka i loko o mea hoʻonoho. Ka mea, i hoʻohana 'ia me kiʻekiʻe-holo ole kiʻekiʻe-anakahi uila kaapuni maʻi o na transformers. Bushing i hoʻouna 'ia palapala ua i ka porcelain, a me ka huina hoonui ua aia i loko o ka'ōlinolino kookoo. Ua Ua paa ma ke kumu o nā flanges i ka mea hiki ke hooheheeia, he porcelain chap pili ana a me ka Padfolio one haku mele 'ana.

Ka lua oʻano reassigned no ka mea ma waho, a no ka pā mea hoʻonoho. Na manao maalea i hana waena iwi aoao e i hoonohonoho i ka uuku mamao mai kekahi i kekahi. Mau manao maalea i papahana no ka'īpale mai ola māhele lelo, switchgear. A bushing o kēia 'ano ua hoʻohana' ia ma ka pae'ōnaehana anakahi uila aʻeo ka hoʻolele '10, 25, 35, 110 kV, a me ka pae'ōnaehana pono o ka mai 630 a hiki i 11.000 A.

Aia nō i nāʻano o nā insulators, akā, ka mea i papahana no ka kekahi pale umauma hoʻokahi palapala noi. peleʻano manaʻo i pono no ka'īpale switchgear lawelawe māhele no ka pili ana o na nā mea kūʻai mai a hiki i ka luhi o ea EYI laina. Mau huahana ua i mai ka mea i hoala i ka pā kaua a hiki i ko lakou manao mea hoʻopale i hōʻeuʻeuʻikena wahie.

pono o insulators

Ke bushing E i ka lōʻihi ola, no laila ia i ke kēia mau 'ano:

• kiʻekiʻe ia'ku iʻano pākīkē pae'ōnaehana ana;
• he kŘpa a uuku kaumaha;
• UV e kū'ē'ē mai;
• kiʻekiʻe ka ikaika;
• lōʻihi hana ke ola;
• kŘpa a uuku Ana.

mea i manao ai IP

Bushings SP pono noho loa me mechanical a me ka uila ikaika, nae ka pono hana a mai a lakou i hana ai, i e like penei:

• pīlali;
• porcelain;
• hui aniani.

Ke insulator ua papahana i ka hālāwai hope anakahi uila uaʻoi kona kiʻekiʻe anakahi uila ano. Mawaho isolators mea mau ma lalo o ka aoao o ka mawaho? Aneie aʻe, no laila lākou ili honua ua Groove. Keia ua hana manaʻoi, e hoʻoikaika i ka hana o ka huahana.

Insulators manaoia subdivided i loko o bushing, kākoʻo a me ka wehe, eia kekahi ano o ka mea hoʻonoho no ka hoʻokomo 'ana i na hale a me nā hale a no foxmike mea hoʻonoho.

Hele SP-10 ua loa pinepine i mai porcelain. Ke constructive manaʻo o ia ka insulator ua nānā 'ia mai ka Loipālākiō anakahi uila a me ka alapine (frequency) o kālepa mana. Ka mea hoʻi he o ka porcelain kino o ka paukūʻolokaʻa kinona, kaa ma axles i kihi a paa i palapala hoopaa me ka hoʻohana i ka lepo pipili-one wili.

ka hoʻokohu 'bushings

I ka papa kuhikuhiE manao o na bushings mea e kaʻawale ka conductors ola, a hele ma na paia a me ka uhi ana o hale a me nā hale. Oia insulators i haku o ka dielectric porcelain. Ke kino ua i loko o ka palapala o ka paukūʻolokaʻa, ma luna o ka a aia no heʻikena-e hali ana i koʻokoʻo. Ma awelika, me ka nui o ka hale metala kaʻikaʻi flanges i, e like me ka hōʻike muaʻia aʻe, manao ia e paa ana i ka insulator ili honua.

Bushing SP ma ka pae'ōnaehana anakahi uila i 10 kV ua i ka porcelain, a ma ka pae'ōnaehana anakahi uila loa 35 kV i ka hale noho ua i like me ka luna ''īpale' ole a, ma ka huli, he o ke kino porcelain, pepa papa, hō'īpale pepa a me ka mea hoʻololi uila aila.

ka piʻiʻana bushings

I ka ka piʻiʻana bushings foxmike nānā 'ia ai no ka mawae a me nā mā, like paha e poino i amo ili o insulators. No hoi nana ina kaʻilikai glaze ua pohole aku, a ua hoʻohana 'ia no ka hou' ohana ka palekana a me ka'īpale nā huahana.

Insulators E e kau ma luna o kekahi mea hiki ke hooheheeia hale, e loaa i ka huina hoonui, e like me ka mea paʻa o ka papale hainaka a me lolo mana laina.

A hāpai bushings hoʻomaka me kau i ka puka pā, a ua pili i ka 'ole ai kekahi fixture. Eia, na insulators ua paa hou mai la ma na aoao elua ma ka papale me ka mea hao keleawe'ōlinolino i pohā ka huinahń puka like alahao hoino aku. Lākou nui hilinaʻi nui ma luna o ka nui o ka luhi o, a, e makaʻuʻole. Ma ka hopena o ka 'atikala ma waena o ka luhi o paa lele struts papale hainaka.

peni bushings

Peni reassigned i mea e kahińuli i nā hiʻona o ke huahana. No ka laʻana, ka mea insulator e hooholo ia SP-10 630 7.5 UHL1, kahi:

• A - he insulator;
• P - kekahi;
• 10 - ka maʻamau pae'ōnaehana anakahi uila o nā huahana (kV);
• 630 - ka mea maʻamau ke hoʻohana he huahana (A);
• 7,5 - wawahi haawe (kn);
• UHL - climatic olelo o ke kanawai;
• 1 - ka mahele o ka noho.

Hālāwai hope anakahi uila o Pi

Hālāwai hope anakahi uila porcelain SP paha e okoa ke kaumaha ma muli o ka mānoanoa o ka porcelain, ahu iho. I loko nō o kēia, i ka insulator 'ole me ka nānā' ana i ke koi 'ia ma paʻi ikaika, Loipālākiō anakahi uila o overlapping a me ka mau ana no ka wehe' ana o ka pāpale aliʻi.

I ka wā o ka bushing 10 kV mai e lawe ana, e wehe i ka corona. Me ka palena iki voltages ma luna o 35 kV e hoʻohana no ana mea hoʻonoho kokoke i ka lei o ke kookoo e ku pono ana i ka mea kākoʻo, e like ma ka wahi, kahi i kā mākou hoʻopilikia i loko o ka lewa.

E pale aku corona, insulators ua hanaʻia me ka lewa lua a puni ka metala kookoo manaʻo i loko o ka insulator. I loko o keia metallizedʻilikai SP me ke kookoo. I mea e hoʻopau i ka hanana o ka hookuuia ma ka lalo SP, kekahi ma lalo iho ili metallized a hou ili.

ka hopena

Paha ka mea i loa ike mea hoʻololi uila lolo laina a i pili i ka SP. i kēia mau mea i mea e pono ai no ka pili ana o na kaula i ka haka nā mea hoʻonoho, no ka mea, me ka insulators hiki ole pilina o kiʻekiʻe-anakahi uila kaula.
