Malo opangira ma miniature circuit breaker

⑴ Kugwirizana kwawowononga derandi wophwanya dera ayenera kuganizira za kutulutsa nthawi yomweyo kwa wophwanya dera lapamwamba, lomwe liyenera kukhala lalikulu kuposa momwe likuyembekezeredwa kuti likhale lalifupi lamakono kumapeto kwa chowotcha chapansi.Ngati mtengo wanthawi yayitali siuli wosiyana kwambiri, woyendetsa dera wapamwamba amatha kusankha gawo laulendo ndikuchedwa kwakanthawi.
⑵ Pamene mphamvu yachidule ikakhala yayikulu kuposa kapena yofanana ndi mtengo wokhazikika wa kutulutsidwa kwanthawi yomweyo kwa chophwanyira chapafupi, chidzayenda mkati mwa ma milliseconds ochepa.Chifukwa chake, sizoyenera kuti zida zodzitchinjiriza zocheperako zigwiritse ntchito chowotcha kuti zikwaniritse zofunikira zachitetezo.
(3) Kwa woyendetsa dera ndi kuchedwa kwafupipafupi, pamene malire ake aikidwa pa kuchedwa kwakukulu, kupanga kwake ndi kuswa mphamvu kumachepa.Chifukwa chake, mugawo lodzitchinjiriza losankha, lingalirani kusankha kuchedwa kwakanthawi ndikuphwanya mphamvu ya wophwanya dera kuti mukwaniritse zofunikira.
⑷ Ziyeneranso kuganiziridwa kuti kuchedwa kwafupipafupi kubwereranso komwe kumakhala koyendetsa dera lapamwamba komanso mawonekedwe a nthawi yodutsa wodutsa dera lapansi sikuyenera kupyola malire, komanso kuchedwa kwafupipafupi komanso mawonekedwe a nthawi yomweyo. sayenera kudumphadumpha.
⑸ Pamene wophwanya dera ndi fuse amagwiritsidwa ntchito palimodzi, kugwirizanitsa kwapamwamba ndi kutsika kuyenera kuganiziridwa.Mapiritsi amtundu wa ampere-second of the circuit breaker ayenera kufananizidwa ndi ampere-second character curve ya fusesi, kuti mukhale ndi chitetezo chosankha pakakhala nthawi yochepa.
⑹ Wowononga dera akagwiritsidwa ntchito poteteza dera logawa, woyendetsa dera wokhala ndi kuchedwa kwanthawi yayitali ayenera kusankhidwa.Pamene gawo limodzi grounding dera lalifupi kumachitika kumapeto kwa mzere, yochepa dera panopa si zosachepera nthawi yomweyo kapena yochepa kuchedwa overcurrent wa wosweka dera 1.5 nthawi anapereka panopa wa gulu ulendo.
