Kushanda kweDropout Fuse Cutout

Kugadzirira kuchengetedzeka:

Pakuburitsa fuse yerudzi rwedonhwe, mushandi anofanira kushandisa tsvimbo yekudzivirira ine voltage yakakodzera uye kupasa bvunzo, kupfeka shangu dzekudzivirira, magirovhosi ekudzivirira, chivharo chekudzivirira uye magogorosi, kana kumira papuratifomu yehuni yakaoma, uye kutarisirwa kuchengetedza kuchengetedzeka kwemunhu.

Zvinyorwa:

Kana mushandisi atanga kana kugumisa fuse yekudhonza kana yekudzima, hapana chinoitika. Kurova uku kuchakuvadza fuse, sekudhonza nekupwanya insulator, kutsausa muromo wedhadha, kudhonza nekutyora rin'i yekushanda, nezvimwewo. Vashandi havafanirwe kushandisa simba rakawanda panguva yekushanda kwefuse yerudzi rwekudonha, kuitira kudzivirira kukuvara kwefuse, uye kupatsanura nekuvharika kunofanira kunge kuripo.

Simba remuchina wefuse rinononoka (kutanga)- nekukurumidza (kana contact iri kufamba iri pedyo ne static contact)- zvishoma nezvishoma (kana contact iri kufamba iri pedyo nekupera kwekuvhara). Maitiro ekudhonza fuse anononoka (kutanga)- nekukurumidza (kana contact iri kufamba iri pedyo ne static contact)- zvishoma nezvishoma (kana contact iri kufamba iri pedyo nekupera kwekudhonza). Kukurumidza kudzivirira short circuit yemagetsi uye kupisa contacts zvinokonzerwa ne arc, zvishoma nezvishoma kudzivirira kushanda kwe impact force, zvichikonzera kukuvara kwe mechanical ku fuse.

Tumira odha

Kutevedzana kwekushanda kwekumisa simba re transformer yekugovera ndekwekuti: Mumamiriro ezvinhu akajairwa, switch ine voltage shoma padivi remutoro inofanira kutanga yadhonzwa, uye fuse ine voltage yakawanda padivi remagetsi inofanira kudhonzwa.

Kana paine magetsi akawanda, zvichienderana nedanho repamusoro rekudzima kwemagetsi, zvinogona kudzivirira transformer kudzokera kumagetsi, kana ikakundikana, dziviriro inogona kuramba kufamba, kuwedzera nguva yekubvisa zvikanganiso, kuita kuti tsaona iwedzere. Kushanda kwemagetsi zvishoma nezvishoma kubva kudivi remagetsi kunogona kuderedza simba rekutanga kwemagetsi (mutoro), kuderedza kushanduka kwemagetsi, uye kuona kuti michina inoshanda zvakachengeteka. Kana paine zvikanganiso, inogona kukanganisa kana kumisa kushanda kwayo, zviri nyore kutarisa, kutonga uye kugadzirisa zvichienderana nehuwandu hwemagetsi. Kana paine kutadza kwemagetsi, misa divi remutoro kutanga. Kana paine kutadza kwemagetsi nhanho nhanho kubva pavoltage yakaderera kusvika pavoltage yakakwira, switch inogona kudzivirira kudzima kuyerera kwemagetsi akawanda uye kuderedza amplitude uye frequency yekushanda pamusoro pevoltage.

Mukushanda, edza kudzivirira kudhonza nekudonhedza mafuse ane mutoro. Kana zvikaonekwa kuti mafuse ane mutoro haana kumira zvakanaka panguva yekushanda, kunyangwe mafuse asina kumira zvakanaka kana kuti arc ikaitika, hazvibvumirwi kuvhura mafuse zvakare. Kana fuse isina kudhonza zvakanaka ine mutoro ikaitika, kana contact ichifamba ikangosiya contact yakatarwa, arc ichaitika. Panguva ino, inofanira kuvharwa nekukasika kuti arc ibviswe uye kudzivirira kukura kwetsaona. Zvisinei, kana mafuse ese akadhonzwa, hazvibvumirwi kuvharazve mafuse akadhonzwa zvisirizvo. Kune ma transformer ekuparadzira ane simba re 200 kva kana pasi, mafuse ari kudivi re high voltage anobvumirwa kuparadzanisa uye kusanganisa load current.

Kurongeka kwekushanda

Kutevedzana kwekushanda kwechikamu chetatu chefuse yekudonhedza voltage ine simba rakawanda.

Kushanda kwemagetsi kukundikana, kunofanira kutanga kwadhonza chikamu chepakati, wozodhonza mativi ese echikamu.

Chikonzero chikuru chekudhonza chikamu chepakati kutanga ndechekufunga kuti magetsi kana chikamu chepakati chabviswa anenge ari mashoma pane chikamu cheparutivi (chikamu chemutoro wedunhu chinotakurwa nezvikamu zviviri), saka arc idiki, uye hapana njodzi kumativi maviri echikamu. Kana fuse yechikamu chechipiri (chikamu cheparutivi) yerudzi rwedrop ichishanda, magetsi acho akakura, nepo chikamu chepakati chadhonzwa chakavhurika, uye mamwe mafuse maviri erudzi rwedrop ari kure, izvo zvinogona kudzivirira short circuit pakati pezvikamu zvinokonzerwa ne arc yakarebeswa. Kana paine mhepo ine simba, tinofanira kutanga tadhonza chikamu chepakati, tobva tadhonza chikamu che lee, uye pakupedzisira todhonza chikamu che windward nenzira yekukundikana kwemagetsi.

Pakutumira magetsi, mativi maviri echikamu chekutanga, mushure mechikamu chepakati.

Kana simba rapfuudzwa, chikamu chekutanga chemhepo, wobva wadzokera kuchikamu chePhoenix, uye pakupedzisira chikamu chepakati, kuitira kudzivirira kupfupika kwemhepo kunokonzerwa nemhepo.

Chinyorwa chekuisa

Kudzivirira pakuisa fuse yekudonhedza ine voltage yakawanda

1, kuiswa kwacho kunofanira kunge kuri kwekunyunguduka kwebvudzi (kunyunguduka neanenge 24.5N), zvikasadaro zviri nyore kukonzera kupisa kwebvudzi.

2, fuse yakaiswa paruoko rwemuchinjikwa (furemu) inofanira kuva yakasimba uye yakavimbika, haigone kuva nechinhu chinozunungusa kana kuzunungusa.

3. Pombi yekunyungudutsa inofanira kunge ine Angle yekunyungudutsa ye25°±2°, kuitira kuti pombi yekunyungudutsa ikwanise kudonha nekukurumidza nehuremu hwayo kana kunyunguduka kwabatanidzwa.

4. Fuse inofanira kuiswa paruoko rwakachinjika (furemu) ine daro rakamira risingasviki 4m kubva pasi. Kana yakaiswa pamusoro pe transformer inogovera, inofanira kuchengetedza daro rakataramuka rinopfuura 0.5m kubva pamuganhu wekunze we transformer inogovera, kana paine dzimwe tsaona dzinokonzerwa nekudonha kwemapombi akanyunguduka.

5. Kureba kwepombi yekunyungudutsa kunofanirwa kugadziriswa nemazvo. Zvinodiwa kuti rurimi rwemuromo wedhadha rugone kukwenya zvinopfuura zvikamu zviviri muzvitatu zvehurefu hwechinogunzva mushure mekuvhara, kuitira kudzivirira chiito chisina kunaka chekudonha chega panguva yekushanda.

6. Kunyunguduka kunoshandiswa kunofanira kunge kuri chigadzirwa chemugadziri wenguva dzose, uye kune simba rakati remuchina. Kazhinji, kunyunguduka kunogona kutsungirira simba rekudhonza rinopfuura 147N.

7. Fuse yerudzi rwe10kV inodonhedzwa yakaiswa panze, uye daro riri pakati pezvikamu rakakura kupfuura 70cm.
