Bushing: Mitundu ndi mitundu

Nkhaniyi itithandiza kudziwa za bushings ndi mitundu ndi mitundu. Tsatanetsatane adzakhala ataphwasula Kapangidwe ka mitundu yosiyanasiyana, mitundu okha, kuchuluka kwawo ndi cholinga. Izo angaonere ubwino poyerekeza ndi zipangizo zofanana. Nditawerenga nkhaniyo, inu osati kuphunzira zambiri za bushings, komanso athe kumvetsa zolemba ndi azitha kusiyanitsa mitundu wina ndi mzake.

Kuchuluka kwa bushings ndi

bushing ndi chiyani? Izi ndi chipangizo wapadera, ntchito yaikulu imene ndi kuonetsetsa kudzipatula zinthu conductive wa mkati kapena kunja mpanda wa m'chimake kudzera limene pochitika. Iwo ntchito yoika zipangizo yogawa wa substations thiransifoma, nawonso amathandiza mu apeza malo Complete kusinthitsa.

Support insulators anapangidwa kuti kukonza mizere pamwamba ndi moyo busbars switchgear ndi makhazikitsidwe zina zamagetsi. M'pofunikanso kuwonjezera kuti zadothi insulators mtundu kuti anali wotchuka kale, ntchito tsiku ndi zambiri zosintha.

The bushings ndi yabwino kwa ntchito kwa malo kugwirizana substations, amene ankayendetsa nyumba.

yonse ya insulators

Bushings anawagawa mitundu iwiri. Yoyamba - ndi insulators, amene cholinga cha unsembe m'nyumba. Iwo ntchito monga mkulu-zingalowe kapena mkulu-voteji malo dera la tiransifoma. Bushing anagonjera mawonekedwe unapangidwa dongo ndipo mankhwala ili mkati ndodo zitsulo. Iwo chili mwa flanges amapangidwa ndi zitsulo, ndi zadothi kapu Ufumuyo ndi yomata mchenga zikuchokera.

Mtundu wachiwiri miza kwa akunja ndi unsembe wa mumtima. makina onga analengedwa nthiti wapakatikati amene anakonza pa mtunda yaing'ono Chrixitu. zipangizozi anapangidwa kuti kutchinjiriza ochokera m'madera moyo akachita switchgear. A bushing wa mtundu uwu ntchito pa misewu opaleshoni voteji 10, 25, 35, 110 kV, ndi opaleshoni panopa kuchokera 630 mpaka 11,000 A.

Palinso mitundu ina ya insulators, koma iwo anapangidwa kuti chandamale ntchito yeniyeni. zipangizo otaya mtundu zofunika magawo kutchinjiriza switchgear conductive kwa kugwirizana ogula kuti tayala mizere mpweya HIV. mankhwala amenewa zopangwidwa kuchokera ku zipangizo anaukitsa linga kuti zinalengedwera kugonjetsedwa ndi katundu zazikulu panopa.

ubwino insulators

The bushing ayenera kukhala ndi moyo wautali, choncho ali ndi makhalidwe awa:

• zonyamula zinthu aukali opaleshoni;
• ndi ochepa thupi;
• UV kukana;
• mkulu mphamvu;
• yaitali moyo utumiki;
• ochepa miyeso.

kamangidwe IP

Bushings SP uyenera kukhala kwambiri mawotchi ndi magetsi mphamvu Koma nkhani zomwe anapanga, kungakhale motere:

• polima;
• zadothi;
• mtima galasi.

insulator lakonzedwa kuti kusokonezeka voteji anali wapamwamba voteji alipo. isolators kunja amakhala mchikakamizo cha zinthu zina zachilengedwe, kotero pamwamba ndi pakati. Izi zachitika makamaka kusintha machitidwe a mankhwala.

Insulators amafunira lophatikizana ndi ubwamunalo linagawanika mu bushing, thandizo kapena kuyimitsidwa, palinso njira yoika kuyika mu nyumba ndi nyumba kapena unsembe panja.

Kudutsa SP-10 nthawi zambiri anapangidwa kuchokera zadothi. Kukhazikitsa zaphindu zimene munthu insulator anatsimikiza ku voteji oveteredwa ndi pafupipafupi mphamvu malonda. The chipangizo palokha imakhala zadothi thupi la mawonekedwe cylindrical, wokwera pa axles amene m'mbali mwamphamvu angongole ntchito matope simenti-mchenga.

Pangano bushings

Cholinga cha bushings ndi kupeza ochititsa moyo, amene kudutsa makoma ndi pogona nyumba kapena nyumba. insulators oterowo lopangidwa ndi dongo dielectric. thupi mu mawonekedwe a yamphamvu ndi pamwamba pa zomwe pali panopa kumangopitirizabe ndodo. Pafupifupi mlingo wa nyumba zitsulo wokwera flanges kumene monga tanenera poyamba, anafuna atathana pamwamba insulator.

Bushing SP pa voteji opaleshoni 10 kV unapangidwa dongo ndipo pa opaleshoni voteji choposa 35 kV nyumba ya kukhala kuipidwa kutchinjiriza dongosolo zimene pamapeto, imakhala ndi thupi zadothi, makatoni mbale, chimateteza pepala ndi mafuta thiransifoma.

ogwiritsa bushings

Pamene ogwiritsa bushings panja chipikisheni kwa ming'alu ndi zilema zina, monga mwina imawonongeka pa zoyendera padziko insulators. Komanso tione ngati pamwamba glaze chatha kutali, amene ntchito anawonjezera mankhwala chitetezo ndi kutchinjiriza.

Insulators adzaikidwe pa nyumba iliyonse zitsulo kuti akalandire mankhwala, komanso durability matayala kapena pamwamba mphamvu mizere.

Khazikitsa bushings akuyamba ndi kuwayika pakhomo mbale, amene anaphatikiza dongosolo kapena fixture iliyonse. Komanso insulators chatsekedwa mbali zonse ndi zisoti ndi partitions chitsulo zitsulo ndi mipata amakona anayi chokhala sitima yapamtunda. kukula zimadalira kukula kwa tayala ndi wotetezedwa. Pa mfundo za nkhani pakati pa tayala atathana wokwera struts matayala.

chodetsa bushings

Chodetsa miza kuti mumatsindikanso mbali zonse za mankhwala. Mwachitsanzo, insulator ndimeyi SP-10 630 7.5 UHL1, m'mene:

• Ndipo - ndi insulator;
• P - pochitika;
• 10 - yawamba opaleshoni voteji la mankhwala (kV);
• 630 - yawamba zikugwira ntchito panopa mankhwala (A);
• 7.5 - kuswa katundu (kN);
• UHL - nyengo kuphedwa;
• 1 - m'gulu la malawi.

Kusokonekera voteji wa PI

Kusokonekera voteji zadothi SP angakhale osiyana malingana ndi makulidwe a wosanjikiza zadothi. Ngakhale izi, dongosolo insulator anatsimikiza ndi chofunika mphamvu mawotchi, oveteredwa voteji ya miyeso zolowerana ndi zina kuchotsa korona.

Pamene bushing 10 kV musatenge miyeso kuchotsa kuŵala kwa m'mlengalenga. Ndi mwadzina voltages pamwamba 35 kV ntchito miyezo unsembe pafupi korona wa ndodo zosiyana flange, basi pa nthawi kumene pazipita mavuto mlengalenga.

Pofuna kupewa kuŵala kwa m'mlengalenga, insulators chopangidwa popanda mpweya M'mimbamo kuzungulira ndodo zitsulo oyenerera mwa insulator lapansi. Pa izi metallized pamwamba SP ndi ndodo. Pofuna kuthetsa pakutchulidwa a kumaliseche pa SP pansi, komanso pansi metallized pamwamba ndi zina chinakhazikika.

Pomaliza

Mwina aliyense anayamba wawonapo thiransifoma pamwamba mizere zimene zaikidwa SP lapansi. zipangizozi zikufunikanso kwa kugwirizana mawaya kuti makhazikitsidwe ndi yoikidwiratu, chifukwa popanda insulators n'zosatheka kugwirizana waya wamphamvu kwambiri voteji.
