Zowononga zozungulira zokhala ndi magalasi osiyanasiyana

Low-voltage frame circuit breaker, ndi ya chipangizo chogawa choyambirira, ndi cholumikizira chamagetsi chochepa kwambiri, chokhala ndi mphamvu zazifupi zosweka komanso kukhazikika kwamphamvu, mawonekedwe oteteza masitepe ambiri, omwe amagwiritsidwa ntchito makamaka mu 10kV/380V. mphamvu thiransifoma 380V mbali, ntchito kugawira mphamvu ndi kuteteza mizere ndi zida mphamvu, Ndi mochulukira, dera lalifupi, pansi voteji, single gawo grounding ndi zina zolakwa chitetezo ntchito ndi kudzipatula ntchito.Universal low-voltage circuit breaker grade grade ovotera panopa nthawi zambiri ndi 200A ~ 6300A, mphamvu yodutsa dera lalifupi ndi 40 ~ 50kA, yokhala ndi njira zitatu zogwiritsira ntchito pamanja, lever ndi magetsi, malire a mphamvu zowonongeka kwa chilengedwe chonse. makina ogwiritsira ntchito kusungirako mphamvu kuti apititse patsogolo liwiro lozimitsa.Makina ozungulira otsika kwambiri amapangidwa makamaka ndi makina olumikizirana, makina ogwiritsira ntchito, chipangizo chotulutsira pakali pano, chida chotulutsa shunt ndi chida chotulutsa pansi pamagetsi, zowonjezera, chimango, waya wachiwiri ndi magawo ena.Zigawo zonse ndi insulated ndi kuikidwa mu zitsulo chimango maziko a insulation liner.Zida zosiyanasiyana zotulutsa ndi zowonjezera zimatha kuphatikizidwa kuti zipange zowononga madera okhala ndi mawonekedwe osankhidwa, osasankha kapena osinthira nthawi.Kuwongolera kwakutali kumatheka kudzera mwaothandizira othandizira.Pali mitundu yambiri ndi mitundu ya ma universal low-voltage circuit breakers, mitundu yambiri, ndi machitidwe osiyanasiyana.Pazikhalidwe zodziwika bwino, zitha kugwiritsidwa ntchito ngati kutembenuka kosasintha kwa mzere.

Chipolopolo cha pulasitiki chamtundu wa low-voltage circuit breaker (chotchedwa pulasitiki-case type low-voltage circuit breaker) ndi chachiwiri chogawa zida zamagetsi.Iwo yodziwika ndi zosiyanasiyana Chalk akhoza kuphatikizidwa mu ntchito zosiyanasiyana za wosweka dera, dongosolo zofunika wapangidwa ndi kutchinjiriza chatsekedwa chipolopolo (zogulitsa zina mandala chipolopolo), makina opaleshoni, kukhudzana ndi arc kuzimitsa dongosolo, matenthedwe maginito kumasulidwa ndi Chalk. 5 magawo oyambira.Zida zoyambira zimaphatikizira chida chomasulidwa chaulere, chida chotulutsa chotenthetsera, cholumikizira chachikulu, batani loyesa, chipata chozimitsa cha arc ndi makina ogwiritsira ntchito.Zida zosiyanasiyana zimatha kusankhidwa malinga ndi zofunikira kuti zikwaniritse zofunikira zosiyanasiyana.

Ma miniature circuit breakers, omwe amadziwikanso kuti modular miniature circuit breakers, amagwiritsidwa ntchito kwambiri m'mabokosi ogawa magetsi kumapeto kwa mizere yogawa magetsi, mabokosi ogawa zowunikira ndi mabokosi ena onse amagetsi, pogawa mizere, ma mota, mabwalo owunikira ndi zida zina zamagetsi. kugawa, kuwongolera ndi chitetezo (kuzungulira kwakufupi, kulemetsa, kutayikira).Chowotcha chozungulira chaching'ono chimakhala ndi makina ogwiritsira ntchito chogwirira, chida chotulutsa matenthedwe, chipangizo chotulutsa ma elekitirodi, makina olumikizirana, arc interrupter ndi zinthu zina, zonse zomwe zimayikidwa m'nyumba yotchinga.Mawonekedwe ake ndi kukula kwa autilaini modular (ambiri a 9mm) ndi njanji yoyikamo, m'lifupi mwake modulus m'lifupi la single-pole (1P) wophwanya dera lazinthu zamakono ndi 18mm (27mm), m'lifupi mwake- pole (1P) wophwanya dera laling'ono-panopa ndi 17.7mm, kutalika kwa khosi lotukuka ndi 45mm, ndipo kuyikako kumagwiritsa ntchito njanji ya 35mm.Malo oyika kumbuyo kwa chophwanyira dera ndi clipping clip yokhala ndi masika amagwiritsidwa ntchito poyika komanso kusokoneza mosavuta.Pali unipolar + neutral (mtundu wa 1P + N), unipolar (1P), awiri (2P), atatu (3P) ndi anayi (4P).
