Zvigadzirwa zvedu

BASIS DATA

33KV-36KV

Iyo inodonhedza-mhando fuse ndiyo inonyanya kushandiswa-pfupi-sekete yekudzivirira switch kune mitsara yebazi ye10kV mitsara yekugovera uye yekugovera shandurudzo.Iyo ine hunhu hwehupfumi, kushanda kwakaringana, kuchinjika kwakasimba kune yekunze nharaunda uye zvichingodaro.Inoshandiswa zvakanyanya muchikamu chekutanga che10kV mitsara yekugovera uye kugovera shandurudzo yekudzivirira uye midziyo yekuchinja uye kucheka kushanda.
 
Yakaiswa pamutsara webazi we 10kV mutsara wekugovera, iyo inogona kuderedza chiyero chekukundikana kwesimba.Nekuda kweiyo yakajeka disconnect point ye-high-voltage drop-type fuse, ine basa rekuzvitsaura switch, iyo inogadzira nzvimbo yakachengeteka yekushanda yemutsetse wekugadzirisa nemidziyo, uye inowedzera pfungwa yekuchengetedzwa kwevashandi vekuchengetedza. Yakaiswa pa kugovera transformer, inogona kushandiswa sechidziviriro chikuru cheshanduro yekugovera, saka yakave yakakurumbira mumutsara wekugovera 10kV uye kugovera transformer.
 

Kuiswa kweiyo drop-type fuse:

(1) panguva yekuisa, kunyunguduka kunofanira kusimbiswa (kuitira kuti kunyungudika kunenge kuine 24.5N tension), kana zvisina kudaro zviri nyore kukonzera kupisa kwebvudzi.

(2) fuse ichaiswa zvakasimba uye yakavimbika pamuchinjikwa (frame) pasina kuzununguka kana kudedera.

(3) pombi yakanyungudutswa inofanira kuva neAngle yekudzika ye25°±2°, kuitira kuti pombi yakanyungudutswa ikwanise kudonha nekukasika nehuremu hwayo pachanyungudika.

(4) fiyuzi ichaiswa paruwoko rwakachinjika (frame) ine chinhambwe chakatwasuka chisingasviki 4m kubva pasi.Kana yakaiswa pamusoro peshanduro yekugovera, kureba kwakadzika pakati pefuse uye yekunze muganhu wekona ye transformer ichachengetwa iri chinhambwe chinodarika 0.5m, kana kune dzimwe njodzi dzinokonzerwa nekudonha kwefuse.

(5) urefu hwefuse huchagadziriswa kusvika pachiyero chepakati.Zvinodiwa kuti rurimi rwedhadha runogona kubata zvinopfuura zvikamu zviviri muzvitatu zvehurefu hwekubatana mushure mekuvhara, kuitira kuti udzivise chiito chisina kunaka chekuzviwisira mukushanda.

(6) kunyungudika kunoshandiswa kunofanirwa kunge kuri zvigadzirwa zvevagadziri venguva dzose, uye kuve nehumwe simba remuchina, izvo zvinodikanwa zvekunyunguduka zvinogona kumira kanenge 147N kupfuura kushushikana.

(7) fiyuzi yemhando yekudonha ye10kV ichaiswa panze uye nhambwe yepakati ichave yakakura kudarika 70cm.
 
Kushanda kweiyo drop-type fuse:

Mumamiriro ezvinhu akajairika, hazvibvumirwi kushanda fiyuzi inodonha nemutoro, inongobvumira kuti ishandise iyo isina-mutoro midziyo (mutsara) .Zvisinei, mashanduri ekuparadzira ane chiyero chepamusoro chisingasviki 200kVA uye mitsara yebazi ye10kV kugovera mitsetse mune zvekurima network. vanobvumirwa kushanda pasi pemutoro zvichienderana nezvinodiwa zvinotevera:

(1) kuvhiyiwa kuchaitwa nevanhu vaviri (munhu mumwechete wekutarisa uye munhu mumwe chete wekushanda), chero vachipfeka magurovhosi anodzivirira, mabhutsu ekudzivirira uye gogi, uye kushanda netsvimbo inodzivirira ine mazinga anowirirana emagetsi.Kushanda kunorambidzwa mumamiriro ekunze emheni kana kunaya kwemvura.

(2) pakudhonza mabhureki, kazhinji inotemerwa kudhonza chikamu chepakati kutanga, kozoti leeward side phase, uye pakupedzisira iyo windward side phase.Izvi imhaka yekuti dhizaini yekugovera kubva kutatu-chikamu kushanda kusvika kune maviri-chikamu chekushanda, dhonza chikamu chepakati chinogadzirwa nediki arc spark, hazvizokonzeresa kupfupika kwedunhu pakati.Yechipiri ndeyekupwanya leeward side phase, nekuti yepakati nhanho yakadhonzwa, iyo leeward side phase uye mhepo yedivi chikamu chinhambwe chakapetwa kaviri, kunyange kana pane overvoltage, zvichiita kuti pfupi dunhu pakati zvingaita shoma chaizvo.Pakupedzisira, apo upwind chikamu chinodhonzwa, chete capacitive ikozvino pasi, chinoguma spark kwave zvishoma.

(3) kana switch yakavharwa, kutevedzana kwekushanda kunodzoserwa kana switch yadhonzwa.Chekutanga, chikamu chekumusoro chinovharwa, ipapo chikamu cheleeward chinovharwa, uye pakupedzisira chikamu chepakati chinovharwa.

(4) kushanda kwechubhu yakanyungudutswa ibasa rinowanzoitwa.Kana iwe ukasazvicherekedza, zvinokonzeresa iyo yekubata kupisa uye kutungamirira kune yakaipa kusangana.Kubatana kunenge kwakanyanyisa uye chitubu chichange chanyungudutswa.Saka, dhonza, vhara chubhu yakanyunguduka kuti umanikidzire zvine mwero, kuvhara zvakanaka, kunyatsotarisa rurimi runogona kusungirira rurimi rurimi zvikamu zviviri muzvitatu zvehurefu hwepamusoro, unogona kudhonza. chiredzo chebhureki pamuromo wedhadha kudzvanya pasi nguva shoma, wobva waedza kudhonza zvinyoro nyoro, tarisa kuti yakanaka here.Kutadza kuvhara switch panzvimbo kana kusavhara zvakasimba, iyo static yekubata pafuse pressure ndiyo. zvisina kukwana, zviri nyore kukonzeresa kupisa kwekubatana kana kunyunguduka kwechubhu
