Overview
Iyo inodonhedza fuse uye load switch fuse ndeyekunze yakakwira-voltage dziviriro michina.Izvo zvakabatana kune mutsara unouya kana mutsara wekugovera wekugovera transformer.Izvi zvinonyanya kushandiswa kuchengetedza transformers kana mitsetse kubva pfupi pfupi, overload uye kushandura ikozvino.Iyo inodonha fuse ine insulator bracket uye fuse chubhu.Iwo ma static contacts akaiswa pamativi ese e insulator bracket, uye zvinofambiswa zvinobatika zvakaiswa kumigumo yese yefuse chubhu.Mukati mechubhu yefuse mune hosi yemoto.Iyo yekunze inogadzirwa ne phenolic composite bepa chubhu kana epoxy girazi.Iyo yekuremedza switch fuse inopa yekuwedzera yekubatsira kubata uye arc yekudzima kamuri yekuvhara yekuvhura / kuvhara mutoro wazvino.
Panguva yekushanda kwakajairika, fuse inodhonzwa kunzvimbo yakavharwa.Pasi pemamiriro ezvinhu aripo, fuse link inonyungudika uye inoita arc.Aya ndiwo mamiriro ekamuri yekudzima arc.Izvi zvinogadzira high pressure muchubhu uye zvinoita kuti chubhu iparadzane kubva kune vanobatika.Kamwe fuse inonyunguduka, simba revabatiki richazorora.Iyo yedunhu breaker ikozvino iri munzvimbo yakavhurika uye mushandisi anofanira kudzima ikozvino.Iwo anofambisa anobatika anogona kubva adhonzwa uchishandisa insulated levers.Main kuonana uye yekubatsira kuonana kwakabatana.
kuchengetedza
(1) Kuita kuti fuse ishande zvakavimbika uye zvakachengeteka, mukuwedzera pakunyatsosarudza zvigadzirwa uye zvishongedzo (kusanganisira fusible zvikamu) zvinogadzirwa nevanogadzira zviri pamutemo zvinoenderana nezvinodiwa nemirairo, zvinhu zvinotevera zvinofanirwa kutariswa zvakanyanya. kune mukushanda nekugadzirisa manejimendi:
① Tarisa uone kana iyo yakayerwa ikozvino yefuse inoenderana nekunyunguduka uye kurodha tsika dzazvino nemazvo.Kana kuenzanisa kusina kunaka, kunofanira kugadziriswa.
② Kushanda kwega kwega kwefuse kunofanira kuchenjerera uye kuchenjerera, kwete kusava nehanya, kunyanya kushanda kwekuvhara.Iwo anochinja uye akamira mabatiro anofanira kunge ari mukubata kwakanaka.
③ Kunyungudika kwakajairika kunofanirwa kushandiswa mupombi yakanyunguduka.Izvo zvinorambidzwa kushandisa waya yemhangura uye aluminium waya panzvimbo yekunyunguduka, uye hazvibvumidzwe kushandisa waya yemhangura, waya yealuminium uye waya yesimbi kuti isungirire kusangana.
④ Kune achangobva kuisirwa kana kutsiviwa fuse, maitiro ekugamuchirwa achaitwa nemazvo, uye zvinodiwa zvemhando yemirairo zvinofanirwa kuzadzikiswa.Iyo yekuisa angle ye fuse chubhu ichasvika anenge 25 °.
⑤ Iyo yakanyungudutswa yakanyungudutswa ichatsiviwa neitsva yezvakatsanangurwa zvakafanana.Hazvibvumirwi kubatanidza iyo yakasanganiswa yakanyunguduka uye kuiisa muhubhu inonyunguduka kuti iwedzere kushandiswa.
⑥ Iyo fuse inofanira kuongororwa nguva dzose, kamwechete pamwedzi manheru, kutarisa kana pane zvinobuda spark uye kusabatwa zvakanaka.Kana pane kubuda, pachava nemheremhere, iyo inofanira kubatwa nokukurumidza sezvinobvira.
(2) Kuongorora kunotevera kuchaitwa kune fuse panguva yekuongorora kwechirimo uye kunze kwekugadzirisa:
① Kunyangwe kubatana pakati peiyo static kubata uye kufambiswa kubata kunoenderana, kwakasimba uye kwakasimba, uye kana paine chiratidzo chekutsva.
② Kunyangwe zvikamu zvinotenderera zvefiyuzi zvinochinjika, zvine ngura, zvisingachinjiki, zvichingodaro, kana zvikamu zvakuvadzwa, uye kuti chitubu chine ngura.
③ Kunyangwe iyo melt yacho pachayo yakuvadzwa kana kwete, uye kana paine yakawandisa yekudziya elongation uye inopera simba mushure menguva refu yemagetsi.
④ Kunyangwe iyo arc suppression chubhu yekugadzira gasi muchubhu inonyunguduka yakapiswa, kukuvara uye kuremara mushure mekusangana nezuva nekunaya, uye kuti kureba kwakapfupikiswa mushure mekuita kwakawanda.
⑤ Chenesa insulator uye tarisa kana pane kukuvara, kuputika kana kuburitsa trace.Mushure mekubvisa ekumusoro neakadzika anotungamira, shandisa 2500V megger kuyedza kudzivirira kwekudzivirira, iyo inofanirwa kunge yakakura kupfuura 300M Ω.
⑥ Tarisa uone kana iyo yekumusoro neyezasi yekubatanidza inotungamira yefuse yakasununguka, yakaburitswa kana kupisa.
Izvo zvakakanganiswa zvinowanikwa muzvinhu zviri pamusoro zvinofanira kunyatsogadziriswa uye kugadziriswa.
Melting tube chimiro:
Iyo fuse inogadzirwa neflberglsaa, inova mwando uye isingadzivirirwe nekuora.
Fuse base:
Chigadziko chechigadzirwa chakamisikidzwa nema mechanical zvimiro uye insulators.Iyo simbi tsvimbo meshini inoiswa neyakakosha adhesive zvinhu uye insulator, iyo inogona kumira pfupi yedunhu ikozvino kuvhura simba.
Fuse-inoratidza unyoro haina mabhubhu, haina deformation, haina dunhu rakavhurika, hukuru hukuru, anti-ultraviolet, hupenyu hurefu, hukuru hwemagetsi zvivakwa, dielectric simba uye yakanakisa mechanical rigidity uye kugona kuzvipira.
Iyo yese michina haina kwayakarerekera, nyore kuisa, yakachengeteka uye yakavimbika.
