Kusiyana pakati pa chophwanyira chozungulira cha kesi ndi miniature circuit breaker

Wowumbidwa mlandu wophwanyira(Mtengo wa MCCB) imapereka chitetezo pakuchulukira komanso kuzungulira pang'ono pamakina otsika amagetsi ogawa mphamvu ndi loop yoteteza magalimoto.Chifukwa cha kudalirika kwake ndi kukhazikika kwake, wakhala akugwiritsidwa ntchito kwambiri m'makampani.Miniature circuit breaker(MCB) imagwiritsidwanso ntchito pamitundu yambiri komanso kuchuluka kwazinthu zowononga dera, ntchito yayikulu ndikuteteza pomanga chipangizo chogawa magetsi.Chifukwa onse ndi a wophwanya dera, ndiMtengo wa MCCBnthawi zambiri amagwiritsidwa ntchito pang'onopang'ono ndikuyimitsa, kotero mvetsetsani kusiyana pakati pa ziwirizi, sankhani chinthu choyenera ndi chowonadi komanso chofunikira.Nawu kufotokozera mwachangu.

Tiyeni tiyambe ndi zofananira, chifukwa onse ndi ophwanya madera, onse amayenera kutsatira mfundo zoyambira, ndipo amagwira ntchito chimodzimodzi.Tiyeni tikambirane kusiyana pakati pawo.Kawirikawiri, pali mfundo zotsatirazi:

1. Zosiyanasiyana zamagetsi
2. Zosiyanasiyana zamakina magawo
3. Malo ogwirira ntchito osiyanasiyana

Kuphatikizanso zomwe zachokera ku Angle of select and buy, nenani masiyanidwe angapo makamaka.

Mavoti apano

Zopangira ma circuit breakerskukhala ndi kalasi yamakono mpaka 2000A.Kuchuluka kwaposachedwa kwapang'onopang'ono wophwanya dera kuli mkati mwa 125A.Chifukwa cha kusiyana pakati pa ziwirizi mu mphamvu, mu ntchito yeniyeni, malo ogwira ntchito ophwanyidwa ndi owumbidwa ndi aakulu kuposakakang'ono circuit breaker, ndi mawaya kupeza ndi wandiweyani, akhoza kufika oposa 35 lalikulu mamita, ndikakang'ono circuit breakerndi oyenera ma 10 masikweya mita otsatirawawaya.Choncho, ambiri m'nyumba, chipinda chachikulu ndi oyenera kusankha kuumbidwa mlandu wosweka dera.

Kuyika

Wowumbidwa mlandu wophwanyiramakamaka wononga wokwera, yosavuta kukanikiza, kukhudzana bwino, ntchito khola.Ndipo chowotcha chozungulira chaching'ono chimayikidwa makamaka kudzera panjanji yowongolera, nthawi zina chifukwa cha torque yosakwanira komanso kusalumikizana bwino.Chifukwa cha njira zosiyanasiyana zoyikamo, zowononga madera owumbidwa zimakhala zokhazikika komanso zovuta kuziyika kuposazazing'ono circuit breakers.

Ntchito ndi moyo

Pogwira ntchito.Wowumbidwa mlandu wophwanyirautenga zida ziwiri kuti ateteze overcurrent ndi dera lalifupi motero, ndi zochita za chitetezo overcurrent akhoza pamanja kusinthidwa, yabwino ndi mofulumira.Zowonongeka zazing'ono zimagawana zida zogwiritsira ntchito mopitirira malire komanso zazifupi, ndipo zamakono sizingasinthidwe, zomwe zimapangitsa kuti nthawi zambiri zisathe kuthetsa vutoli.Pulasitiki mlandu dera wosweka gawo mtunda, ndi chivundikiro cha arc, arc kuzimitsa mphamvu ndi wamphamvu, akhoza kupirira wamkulu yochepa dera panopa, ndipo si zophweka chifukwa gawo lalifupi dera, kuti moyo utumiki ndi kuposa kakang'ono dera wosweka.

Kusinthasintha kwa ntchito

Pachifukwa ichi,kuumbidwa nkhani circuit breakersndizodziwika kwambiri, ndipo kusinthasintha kwawo pakukhazikitsa ndikwabwinoko kuposa zophwanyira zazing'ono.The overcurrent and short circuit chitetezo zipangizo zaMtengo wa MCCBndizodziyimira pawokha, ndipo phindu lachitetezo chopitilira muyeso lingasinthidwe mosavuta.Kutetezedwa kopitilira apo komanso chitetezo chachifupi chozunguliraMCBndi zida zogwirizana, ndipo pali zofooka zina pakusinthasintha kwa malamulo.Malinga ndi pamwamba zinthu zikuoneka kuti MCB mu mphepo, koma kwenikweni kwa nthawi, kapena ayenera kusankhaMCB.

Mwachitsanzo, kufunikira kokonzanso chitetezo cha mzere, chifukwa mphamvu ya MCB yogwira ntchito ndipamwamba, kuswa kuchitapo kanthu kumathamanga, kumapangitsa chitetezo cha chingwe ndi zipangizo zamagetsi.Zitha kuwoneka kuti onse ali ndi ubwino wawo komanso oyenera kugwiritsidwa ntchito, chinsinsi ndikumvetsetsa kusiyana pakati pawokuumbidwa mlandu circuit breakerndi kakang'ono dera wosweka, ndipo malinga ndi zosowa zawo kusankha.
