Overview

Drop out fuse chishandiso chekunze chekudzivirira chakakwira-voltage.Ndiyo inonyanya kushandiswa kupfupika kwekudzivirira kushandura mitsara yebazi yemitsara yekugovera uye kugovera kushandura.Inonyanya kushandiswa kuchengetedza vashanduri kana mitsara kubva pamigumisiro inokonzerwa nepfupi pfupi, kuremerwa uye kuchinja ikozvino.Iyo ine hunhu hwehupfumi, kushanda kwakaringana uye kuchinjika kwakasimba kune yekunze nharaunda.Pasi pemamiriro ekukanganisa ikozvino, fuse inoputika uye inoita arc.Iyo arc yekudzima chubhu inodziya uye inoputika, zvichikonzera high voltage.Iyo fuse ikozvino iri panzvimbo yakashama uye mushandisi anofanira kudzima ikozvino.Kuvhara ne insulating inopisa tepi.Iyo huru yekuonana uye yekubatsira yekubatanidza yakabatanidzwa.Yakaiswa pamutsara webazi we 10kV mutsara wekugovera, iyo inogona kuderedza simba rekubuda kwemagetsi.Nemhaka yokuti ine nzvimbo yakajeka yekubatanidza, ine basa rekubvisa kushandura, kugadzira nzvimbo yakachengeteka yekushanda kwemitsara nemichina muchikamu chekugadzirisa, uye kuwedzera pfungwa yekuchengeteka kwevashandi vekuchengetedza.

Kugadzirisa matambudziko

(1) Iyo fuse kudivi rekutanga retransformer inoshandiswa sechidziviriro chekuchengetedza iyo transformer pachayo uye yechipiri divi rinobuda mutsara kukanganisa.Inopindirana nenguva yechiito ye substation inobuda mutsetse switch relay dziviriro, uye inofanira kunge iri shoma pane yekutyora nguva ye substation outlet circuit breaker.Izvo zvinodikanwa kuti fuse isanganiswa uye iyo yekubuda wedunhu breaker haiite.Kana iyo transformer simba iri pasi pe 100kV.A, fuse padivi rekutanga inogona kusarudzwa se 2-3 nguva dzeyero yakatarwa;Kune shanduri yekugovera ye100kV.A uye pamusoro, fuse padivi rekutanga inogona kusarudzwa se 1.5 ~ 2 nguva dzeyakayerwa ikozvino.

(2) Mutsetse mukuru webazi unonyanya kushandiswa kudzivirira kuwandisa.Kazhinji, iyo yakarongerwa ikozvino yefuse inosarudzwa maererano nehuwandu hwekutakura huripo hwemutsara webazi.Iyo yekusanganisa nguva inofanirwa kunge iri shoma pane yekumisikidza nguva ye substation inobuda mutsara chinja ikozvino kudzivirira mudziyo.

(3) Iyo yekushanda uye yekuchengetedza account uye hurongwa hwekudonhedza fuse ichasimbiswa.Drop out fuses anga achishanda kweanopfuura makore 5 achatsiviwa mumabhechi.

(4) Kuvandudza hunyanzvi hwemhando uye maitiro ekugadzirisa emagetsi.Pakuisa kana kutsiva fuse, simba racho richave rakakodzera kudzivirira kusununguka zvakanyanya kana kusimba zvakanyanya.

(5) Nezvekukanganisa kwekukanda kumagumo ese efuse chubhu, mugadziri achaita "chamfering" kurapwa kana kugadzirisa zvimwe.

Kuiswa kwemafusi ekudonha

(1) Panguva yekuisa, kunyunguduka kunofanira kusimbiswa (kuitira kuti kunyunguduka kugone kumira nechisimba chinenge 24.5N), kana zvisina kudaro kusangana kunogona kupisa.Iyo fuse yakaiswa pamuchinjikwa ruoko (frame) ichave yakasimba uye yakavimbika pasina kuzununguka kana kuzununguka.

(2) Iyo chubhu inonyunguduka ichava nekona yekudzika ye25 ° ± 2 °, kuitira kuti chubhu inonyunguduka inogona kudonha nekukurumidza nehuremu hwayo painofuridza kunze kunyungudika.

(3) Iyo fuse ichaiswa pamuchinjikwa ruoko (frame).Nezvikonzero zvekuchengetedza, kureba kwakamira kubva pasi hakuzove pasi pe4m.Kana iyo yakaiswa pamusoro peshanduro yekugovera, chinhambwe chakatwasuka chinodarika 0.5m chichachengetwa kubva kumuganhu wekunze we contour yekugovera transformer.Kudonha kwepombi yakanyunguduka kwakakonzera dzimwe tsaona.

(4) Kureba kwefuse kunofanira kugadziriswa zvakakodzera.Mafungiro ekuchengetedza anoda kuti duckbill rinogona kuchengeta zvinopfuura zvikamu zviviri muzvitatu zvehurefu hwekubata mushure mekuvharwa kudzivirira kudonha misoperation panguva yekushanda.Iyo fuse chubhu haifanire kubata duckbill kudzivirira chubhu inonyunguduka kuti isadonha nenguva mushure mekunge kunyungudika kwapeperetswa.

(5) Kunyungudika kunoshandiswa kunofanirwa kunge kuri chigadzirwa chemugadziri wenguva dzose uye kuve nehumwe simba remagetsi.Kufunga nezvekuchengetedza kazhinji kunoda kuti kunyunguduka kugone kumira nesimba rinopfuura 147N.

(6) 10kV drop out fuse inoiswa panze kuitira kuchengetedza uye chinhambwe chinodiwa kuti chive chinopfuura 70cm.

Cherechedza: Kazhinji, hazvibvumirwi kushandisa fiyuzi yekudonha pamutoro, asi inobvumirwa chete kushandisa michina isina-mutoro (mutsara).Zvisinei, mumamiriro ezvinhu chaiwo, inobvumirwa kutakura sezvinodiwa
