Zosankha za mtundu wa Yuye zopangidwa ndi case circuit breaker

Malinga ndi kapangidwe ka gulu la ophwanya dera, pali mtundu wapadziko lonse lapansi, mtundu wa chipolopolo cha pulasitiki, chophwanya pulasitiki, chomwe chili choyenera kuvotera voteji 690V, ma frequency 50/60Hz, ovotera pano 16 mpaka 1600A kapena ngati thiransifoma, mota , capacitor ndi zida zina zotetezera.Makamaka kugawira mphamvu yamagetsi, kuchita nthambi ndi zida zamagetsi zimamuchulukira, dera lalifupi, kutayikira mfundo ndi chitetezo pansi-voteji, angagwiritsidwenso ntchito mzere ndi zida zamagetsi si kawirikawiri kutembenuka.Amagwiritsidwa ntchito kwambiri m'mafakitale ndi ulimi, zoyendera, migodi, zomangamanga ndi chitetezo cha dziko ndi madipatimenti ena, kufalitsa ndi kugawa mphamvu, kulamulira dera ndi chitetezo kumagwira ntchito yaikulu, ndi ntchito yaikulu, mitundu yosiyanasiyana ya mankhwala.Chifukwa ogwiritsa ntchito samamvetsetsa zaukadaulo ndi zofunikira za MCCB mozama kapena mokwanira, malingaliro ena ndi osavuta kusokonezedwa wina ndi mnzake, ndipo nthawi zambiri pamakhala zolakwika ndi kusamvetsetsana pakugwiritsa ntchito.Zofunikira zomwe wogwiritsa ntchito ayenera kuziganizira posankha ndikugwiritsa ntchito MCCB zimayambitsidwa mwatsatanetsatane.Tsopano, kufotokozera kwa chipolopolo cha chipolopolo cha chophwanyacho chimagwiritsidwa ntchito kuthandiza wogwiritsa ntchito kusankha kugwiritsa ntchito MCCB.

Circuit breaker shell bracket giredi

Circuit breaker housing frame rating ndi nthawi yovotera paulendo waukulu womwe ungathe kuikidwa pa chimango ndi nyumba zapulasitiki zofanana.

Zomwe zimavoteledwa paulendo wodutsa dera ndizomwe ulendo wodutsa dera ungadutse kwa nthawi yayitali, womwe umadziwikanso kuti voteji yaulendo wodutsa dera.

Pali mitundu yosiyanasiyana ya mafelemu a chipolopolo pakali pano pamndandanda womwewo, ndi mitundu yosiyanasiyana ya mavoti apano mu chipolopolo chofananacho.Mwachitsanzo, pali 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A ndi 100A oveteredwa panopa mu 100A chipolopolo ndi chimango mlingo;Pali 100A, 125A, 160A, 180A, 200A, 225A oveteredwa panopa mu 225A chipolopolo ndi chimango kalasi.Pali 100A yomwe idavotera pakadali pano m'makalasi onse a 100A ndi 225A, koma kukula, mawonekedwe ndi kusweka kwa wophwanya dera ndizosiyana.Chifukwa chake, mtunduwo uyenera kudzazidwa kwathunthu posankha, ndiye kuti, kuchuluka kwamagetsi kwa woyendetsa dera mkati mwazomwe zidavotera pagulu lachipolopolo.Magulu omwe adavotera pano amasankhidwa molingana ndi gawo loyambirira la (1.25): mbali imodzi, imakwaniritsa ndikukwaniritsa zofunikira zapanthawi yoyezetsa pakali pano ya dera ndi zida zamagetsi;Zina ndi za standardization, kuti apeze kugwiritsa ntchito bwino waya ndi kukonza mapindu.Chifukwa chake, magiredi omwe amapereka ndi awa: 3(6), 8, 10, 12.5, 16,20, 25, 32, 40, 50, 63, 80,100, 125, 160, 200, 250, 315, 400A, etc. za lamulo ili, pamene katundu wowerengeka wa mzere ndi 90A, ndondomeko ya 100A yokha ingasankhidwe, kotero kuti chitetezo chake chimakhudzidwa pamlingo wina.

Zokonda pakalipano za Tripper ndipamene wodutsa amasinthidwa kuti agwirizane ndi mtengo wapano.Ilo limatanthawuza pakali pano Mu angapo, ndi mtengo wa zochita panopa, mwachitsanzo: overcurrent anapereka 1.2, 1.3, 5, 10 nthawi panopa, amalembedwa IR = 1.2In, 1.3In, 5In, 10In, etc. Tsopano ma trippers ena apakompyuta, kuchulukira kwake komanso kuchedwa kwanthawi yayitali komwe kumawerengedwa pano kumasinthidwa, kusinthidwa kwapano, kwenikweni, kukadali komweko komweko, ndiko kupitilira apo komwe kungadutse kwa nthawi yayitali.

Mphamvu yomwe ikugwira ntchito ndiyomwe ikugwira ntchito pamagetsi enaake ogwira ntchito pamene othandizira (zowonjezera) aikidwa.Pakalipano ndi 3A kapena 6A, yomwe imagwiritsidwa ntchito kulamulira ndi kuteteza dera.
