Chigadzirwa Chimiro maficha uye chiyero chekushandiswa

Melt tube chimiro:
Fuse inotora yakagadzirwa neflberglsaa, inonyorova-inopupurirwa & corrosion-proof.
Fuse base:
Chigadzirwa chigadziko chakamisikidzwa mechanical chimiro uye insulator.Isa simbi tsvimbo meshini uchishandisa yakakosha binder zvinhu uye insulator pamwe chete, inogona nekumira ipfupi-yedunhu ikozvino kuvhura simba remagetsi.
Fuse isina kunyorova haina blister, deformation, yakavhurika, yakakura kugona, UV, hupenyu hurefu, epamusoro magetsi zvivakwa, dielectric simba uye yakanakisa mechaniki kuoma uye kugona kwakatsaurwa.
The yose sangano kuti kwazvakarerekera, nyore kugadzwa, yakachengeteka uye yakavimbika.
1. The ambient tembiricha haina kupfuura +40 C, kwete kuderera pane-40 C
2. Kukwirira hakupfuuri 3000m
3.Mhepo yepamusoro yemhepo haipfuuri 35m / s
4. Kudengenyeka kwepasi hakupfuuri madhigirii masere

Kuiswa kweFuse uye Kushanda

1. Kuiswa kwefusi yekudonha:
(1) Kunyungudika kunofanira kusimbiswa panguva yekuisa (kuitira kuti kunyunguduka kuve pasi pesimba rinotyisa rinenge 24.5N), zvikasadaro zviri nyore kuita kuti kusangana kuwedzere.
(2) Fuse yakaiswa pamuchinjikwa ruoko (frame) inofanira kuva yakasimba uye yakavimbika, uye hapafaniri kuva nekudedera kana kuzununguka.
(3) Iyo chubhu yakanyunguduka inofanira kuva nekona yekudzika yakadzika ye 25 ° ± 2 °, kuitira kuti chubhu inonyunguduka inokurumidza kudonha nehuremu hwayo kana kunyungudika kwaputika.
(4) Fuse inofanira kuiswa pamuchinjikwa ruoko (frame) ine vertical distance isingasviki 4m kubva pasi.Kana iyo yakaiswa pamusoro peshanduro yekugovera, inofanirwa kuchengetedza yakatwasuka kureba inopfuura 0.5m kubva kune yekunze contour muganhu wekugovera transformer.Kudonha kwechubhu inonyungudika kwakakonzera dzimwe tsaona.
(5) Kureba kwechubhu yefuse kunofanira kugadziriswa zvine mwero.Zvinodiwa kuti rurimi rweduckbill rugone kubata zvinopfuura zvikamu zviviri kubva muzvitatu zvehurefu hwekusangana mushure mekuvhara, kuitira kuti udzivise misoperation yekuzviwisira panguva yekushanda, uye fuse tube haifaniri kurova duckbill., kuitira kudzivirira kunyunguduka kwechubhu kubva pakudonha munguva mushure mokunge kunyunguduka kwaputika.
(6) Kunyungudika kunoshandiswa kunofanirwa kuve kwakajairwa chigadzirwa chemugadziri wenguva dzose, uye kune imwe mechanical simba.Kazhinji, kunyungudika kunodiwa kuti kumire simba rinopfuura 147N.
(7) Iyo 10kV yekudonhedza fuse inoiswa panze, uye chinhambwe chiri pakati pezvikamu chinodiwa kuti chive chinopfuura 70cm.
Chechipiri, kushanda kwefuse yekudonha:
Mumamiriro ezvinhu akajairika, hazvibvumirwi kushandisa fuse yekudonha nemutoro, chete inobvumirwa kushandisa michina isina-mutoro (mutsara).Nekudaro, mitsara yemapazi ye10kV mitsara yekuparadzira mumagidhi emagetsi ekumaruwa uye matransformer ekuparadzira ane chiyero chakayerwa chisingasviki 200kVA anotenderwa kushanda nemutoro zvinoenderana nezvinotevera zvinodiwa:
(1) Oparesheni iyi ichaitwa nevanhu vaviri (mumwe kuti atarise uye mumwe ashande), asi anofanirwa kupfeka magurovhosi anodzivirira, mabhutsu ekudzivirira, uye gogi, uye kushanda netsvimbo inodzivirira ine mazinga anoenderana nemagetsi.Kushanda kunorambidzwa pakunaya kukuru.
(2) Panguva yekushanda kwegedhi, zvinogarotaurwa kuti chikamu chepakati chinodhonzwa kutanga, kozoti chikamu cheleeward chinodhonzwa, uyezve chikamu chedivi chemhepo chinodhonzwa.Izvi zvinodaro nekuti iyo shanduri yekugovera inoshandurwa kubva panhatu-chikamu kushanda kune maviri-chikamu kushanda, uye iyo arc spark inogadzirwa kana chikamu chepakati chaputsika idiki, izvo zvisingazokonzeresa pfupi pfupi pakati pezvikamu.Yechipiri ndeyekupwanya chikamu cheleeward side, nekuti chikamu chepakati chakadhonzwa nepakati, uye chinhambwe chiri pakati pechikamu cheleeward side nechikamu chemhepo chakapetwa kaviri.Kunyangwe kana paine overvoltage, mukana wepfupi wedunhu pakati pezvikamu idiki kwazvo.Kana iyo mhepo yedivi chikamu ichidhonzwa kumashure, pane chete capacitive ikozvino pasi, uye spark inogadzirwa ishoma.
(3) Kana uchivhara, kutevedzana kwekushanda kunodzoserwa kumashure kana uchivhara, tanga wavhara chikamu chemhepo, wozovhara chikamu cheleeward, wozovhara chikamu chepakati.
(4) Kushandisa chubhu inonyunguduka chinhu chinowanzoitika.Kana iwe ukasateerera, zvinokonzeresa kuti kubatana kupfute uye kukonzeresa kusaonana, kuwedzeredza kusangana, uye anneal chitubu, izvo zvinoita kuti kusangana kuwedzere uye kuita denderedzwa rakashata.Naizvozvo, pakudhonza nekuvhara fusion chubhu, shandisa zvine mwero simba.Mushure mekuvhara, nyatsotarisa kuti rurimi rweduckbill runogona kusungirirwa zvakasimba kweanopfuura zvikamu zviviri kubva muzvitatu zvehurefu hwerurimi.Unogona kushandisa brake lever kukochekera duckbill repamusoro uye wodzvanya pasi kakati wandei.Edza kudhonza zvakare kuti utarise kuti inokwana here.Kana shanduko yakavharwa, haisi panzvimbo kana kuti isina kuvharwa zvakasimba, uye static contact pressure pa fuse haina kukwana, izvo zvinogona kuita nyore kuti kubatana kunopisa kana fuse tube inowira yega.
