Cholinga chachikulu
Fuseyi ndi yoyenera kwa mzere wochulukira komanso chitetezo chafupipafupi pazida zogawira zida zamagetsi zamagetsi ndi AC oveteredwa pafupipafupi 50Hz, oveteredwa voteji ya AC kuti 690V, DC 250V kuti 440V ndi oveteredwa cunent kuti 1250A.
1.2Mtundu ndi mawonekedwe
Mtundu ndi mawonekedwe
Fuse imagawidwa m'magulu asanu ndi limodzi molingana ndi kukula kwa fuse chubu.Kukula kulikonse kuli ndi mtundu wapano wovotera.Onaninso zaumisiri zazikulu zovotera mulingo wa fuse wamitundu yosiyanasiyana.Fuseyi imatha kukhala ndi cholumikizira molingana ndi zomwe wogwiritsa ntchito amafuna, ndipo chowongoleracho chimakhala pamwamba pa cholumikizira.
Nomenclature ya fuse
Nthawi zogwirira ntchito
◆ Kutentha kwa mpweya wozungulira
Kutentha kwa mpweya wozungulira sikuyenera kupitirira 40 ° C, mtengo wapakati woyezedwa mu maola 24 sudzapitirira 35 C, ndipo mtengo wapakati woyezedwa m'chaka chimodzi udzakhala wotsika kuposa mtengo umenewu.
Kutentha kochepa kwa mpweya wozungulira ndi 5 C.
◆ Kutalika
Kutalika kwa malo oyikapo sikuyenera kupitirira 2000m.
◆Mikhalidwe ya mumlengalenga
Chinyezi chake sichiyenera kupitirira 50% pa kutentha kwakukulu kwa 40 ° C
Chinyezi chapamwamba chikhoza kupezeka pa kutentha kochepa, mwachitsanzo, mpaka 90% pa 20C.
Pazifukwa izi, condensation yapakati imatha kuchitika mwangozi chifukwa cha kusintha kwa kutentha.Popanda kuyanjana ndi wopanga, fusesiyo singayikidwe pamalopo ndi nkhungu yamchere kapena gawo lazambiri la mafakitale.
◆ Mphamvu yamagetsi
The pazipita dongosolo voteji sayenera upambana 1 10% ya oveteredwa fuse voteji.
Kwa fuse yokhala ndi voteji ya 690V AC ndi 250V 1440V DC, mphamvu yayikulu yamagetsi siyenera kupitilira 105% yamagetsi ovotera a fuse.
Normal unsembe zinthu
◆Kuyika gulu
Gulu loyika fuse ndi kalasi I.
◆ Mulingo wa kuipitsa
Digiri ya anti kuipitsa ya fuse siyenera kukhala yotsika kuposa level3.
◆Kuyika mode
Fuseyi imatha kukhazikitsidwa molunjika, mopingasa kapena mozungulira pamalo ogwirira ntchito popanda kugwedezeka kwakukulu komanso kugwedezeka.
Kuphwanya osiyanasiyana ndi ntchito gulu
Ulalo wa fusewu wa fusewu ndi ulalo wa fusesi wokhala ndi cholinga chambiri komanso kutha kwamitundu yonse, mwachitsanzo, ulalo wa "gG".
Zomangamanga ndi mfundo zogwirira ntchito
Fuseyi imakhala ndi fuse base ndi ulalo wa fuse.Fuse base imapangidwa ndi maziko olumikizana, mbale yoyambira, ndi zina. Ulalo wa fusewu umapangidwa ndi fuse chubu, kusungunula, mchenga wa quartz, kukhudzana kwa mtundu wa mpeni, ndi zina zambiri.
Pamene fusesi imayikidwa mu dera, pamene fusesi ikudutsa mu fuseyi iposa mtengo wina kwa nthawi yokwanira, kusungunuka mu fuseji kumasakanikirana, ndipo arc imapangidwa pamene fuseyo imasakanikirana ndi mchenga wa quartz mu fuseji. chubu adzazimitsidwa, kuti akwaniritse cholinga chophwanya dera.
Kusungunuka kukawomberedwa, chizindikiro pa ulalo wa fusewu chidzatulukira, kusonyeza kuti ulalo wa fusewu ukuwomberedwa.
Kwa fuse yomwe ili ndi impactor, chisungunukocho chikaphatikizidwa, choponderacho chimangotuluka chokha.Wogwiritsa ntchito amangofunika kukhazikitsa micro-switch kapena chipangizo choyenera chotumizira chizindikiro (chosankhidwa ndi kugulidwa ndi wogwiritsa ntchito) kutsogolo kwa chothandizira, ndiyeno chizindikiro chofunikira chikhoza kupezedwa fuseyo itasakanikirana.

5. Kuyika, kugwiritsa ntchito ndi kukonza fusesi
Fuseyi idzayikidwa m'nyumba kapena mu kabati yomwe sichidzakhudzidwa ndi mvula ndi chipale chofewa, ndipo sichidzawululidwa ndi kuikidwa pamalo osavuta kukhudza.Mukayika fusesi, onetsetsani kuti chilolezo chamagetsi ndi chachikulu kuposa 8 mm ndipo mtunda wa creepage ndi waukulu kuposa 10 mm. M'derali, gawo lozungulira la waya wolumikizira likulimbikitsidwa ngati mtengo mu Table 4.

Ulalo wa fuseyo ukawomberedwa, ulalo wa fusesi watsopano wokhala ndi mtundu womwewo, kukula kwake ndi mawonekedwe apano monga ulalo wa fuseyo woyambirira uyenera kusinthidwa m'malo mwa waya wamkuwa.
Kusintha kwa maulalo a fusesi kudzachitidwa ndi akatswiri pogwiritsa ntchito zonyamulira zapadera za fuse.
Mukasintha ulalo wa fusesi, uyenera kuchitidwa popanda katundu, makamaka pamene magetsi atha.Sizololedwa kugwiritsa ntchito fusesi kuti mudule kapena kulumikiza katunduyo pamene chosinthira chikugwiritsidwa ntchito.Mukasintha ulalo wa fusesi, onetsetsani kuti kulumikizana pakati pa ulalo wa fusesi ndi kulumikizana koyambira ndikulumikizana bwino.
Mukathimitsa magetsi ndikuyika ulalo wa fusesi, chonde chotsani fumbi ndi dothi lina pamunsi pa fuse, makamaka kukhudzana ndi maziko, kuti fuseyo ikhale yogwira ntchito bwino.
Panthawi yogwira ntchito, chizindikiro cha ulalo wa fuse iyenera kuyang'aniridwa pafupipafupi kuti mudziwe gawo limodzi kapena gawo lomwe likusowa panthawi yake.
Kuyendetsa ndi kusungirako fusesi
Fuseyi iyenera kutetezedwa ku mvula ndi matalala panthawi yoyendetsa ndi kusunga.Kutsika kwaulere kwa fusesi yonse ya bokosi sikuyenera kupitirira 250mm.
Ma fuse adzasungidwa pamalo ozungulira mpweya komanso malo owuma, ndipo kutalika kwa stacking sikudutsa zigawo zisanu ndi chimodzi.
Kutsegula ndi kuyang'ana fuse
Mutatha kumasula, fufuzani kaye ngati nameplate ya fuseyo ikugwirizana ndi mndandanda wazolongedza ndi chizindikiro pabokosi lolongedza katundu, ndiyeno onani ngati chomangira pa fuse m'munsi kapena fuse ulalo ndi lotayirira kapena kugwa o比 onani ngati porcelain chubu cha Fuse link yathyoka kapena yosweka, fufuzani ngati mchenga wa quartz mu fuse block ukutuluka, ndipo fufuzani ngati fuseyo yanyowa kapena kumenyedwa ndi madzi.Ngati zomwe zili pamwambazi zapezeka, fusesiyo siyingagwiritsidwe ntchito, ndipo wopanga adzalumikizidwa munthawi yake.
Bokosi la fusesi liyenera kukhala ndi satifiketi yazinthu, mndandanda wazonyamula ndi malangizo ogwiritsira ntchito.
Kuyitanitsa malangizo
Mukayitanitsa ma fuse, mtundu, mawonekedwe, kuchuluka ndi mtundu waposachedwa wa maulalo a fuse omwe akuyenera kuwonetsedwa.Fuse base ndi fuse ulalo zitha kuyitanidwa padera.
Pama fuse amatchulidwe apadera komanso milingo yamakono, wopanga adzafunsidwa akamayitanitsa.
