Low voltage switch (low voltage circuit breaker) imatchedwanso automatic air switch kapena automatic air circuit breaker.Zimagwirizanitsa zowongolera ndi ntchito zambiri zachitetezo.Pamene mzerewo ukugwira ntchito bwino, umagwiritsidwa ntchito ngati chosinthira mphamvu kuyatsa ndi kuzimitsa dera.Ikayatsidwa, imakhala yofanana ndi gawo la waya wopatsa mphamvu.Dera likakhala ndi dera lalifupi, lodzaza ndi zolakwika zina, limatha kudula gawo lolakwika.Chifukwa chake, kusintha kwamagetsi otsika kumatha kuteteza dera ndi zida.
Tanthauzo la zida zamagetsi zotsika mphamvu: zimatanthauzidwa molingana ndi kukula kwa voteji, voteji yovotera mu AC iyenera kukhala yosakwana 1200V, ndipo magetsi ovotera ku DC ayenera kukhala osakwana 1500V.
Kugwiritsa ntchito masiwichi otsika kwambiri kumapangitsa kuti magetsi aziyenda mokhazikika komanso motetezeka.Gulu lachindunji lili motere:
Malinga ndi mawonekedwe osiyanasiyana amkati a switch-voltage switch, imatha kugawidwa kukhala chosinthira cholumikizira ndi chosinthira pansi.Mfundo yoyendetsera zonse imayendetsedwa ndi fusesi yosinthira.Kutengera njira yodzipatula, itha kugwiritsidwanso ntchito posinthira katundu ndi masiwichi a fuse.Malinga ndi njira zosiyanasiyana zotsekera zosinthira, zimathanso kugawidwa kukhala zotseguka komanso zotsekedwa.Posankha, zimatengera momwe zinthu zilili.
Low-voltage isolate switch ndi mtundu wodzipatula.Ndiwosintha omwe amagwiritsidwa ntchito kwambiri pamagetsi apamwamba kwambiri.Zimagwira ntchito yofunika kwambiri pakukhazikitsa ndi kutetezedwa kwa magetsi.
Mukadula katundu wamakono, chosinthira chodzipatula chotsika-voltage sichingadutse mtengo wake wololeka.Ma switch odzipatula otsika-voltage amtundu wamba saloledwa kugwira ntchito ndi katundu, ma switch odzipatula okha otsika-voltage okhala ndi zipinda zozimitsira arc amatha kuloleza ntchito yocheperako pang'ono.Ndikoyenera kudziwa kuti gawo laling'ono lachidule la magawo atatu la mzere pomwe chosinthira chodzipatula chochepa chamagetsi sichiyenera kupitilira kuchuluka kwamphamvu komanso kukhazikika kwamafuta.
Low voteji kudzipatula lophimba ntchito:
1. Kusinthana kudzipatula kumatha kukhala ndi zotsatira zabwino zotsekereza, kuti dera lonselo likhale lotetezeka komanso lotetezeka, ndipo ogwira ntchito yosamalira kapena ogwira ntchito amathanso kukonza dera munthawi yake.
2.Kuonjezera apo, kusintha kwapadera kwapadera kumakhala ndi ntchito yosinthira dera, ndipo masinthidwe oterewa amagwiritsidwa ntchito kwambiri m'mafakitale amagetsi.Chitsanzo ndi ichi: mzere wopangira uyenera kusintha ndondomeko yazinthu kapena zitsanzo.Panthawiyi, kusinthana kwapadera kumatha kusintha njira yoyendetsera dera podula magetsi, kuti muwonjezere phindu la dera.
3.Kuphatikiza ndi ntchito zomwe zili pamwambapa, chosinthira chodzipatula chochepa chamagetsi chimatha kulumikizanso mzere.Mu zida zotsika mphamvu za nyumba zogona kapena nyumba zambiri, chosinthira chodzipatula chimachepetsa ngozi yobisika ya ngozi zachitetezo pogwiritsa ntchito osagwiritsa ntchito manja.Izi zimapangitsa moyo wathu kukhala wosavuta komanso ntchito yogawa ndi kufalitsa mphamvu.
Chosinthira pansi ndi chosinthira chomwe chimagwiritsidwa ntchito kulumikiza kapena kudula gawo loyambira la zida zamagetsi ndi magetsi.Ntchito yake yayikulu ndikuletsa kulephera kwanthawi yayitali kapena kulumikizidwa mwangozi kwa zida zamagetsi, kuteteza chitetezo chamunthu komanso kugwiritsa ntchito bwino zida zamagetsi.
1. Chitetezo cha machitidwe
Mu machitidwe a mphamvu, zolakwa za pansi ndizochitika wamba.Pamene vuto la pansi likupezeka mu zipangizo zamagetsi, zidzatsogolera kuchepetsa mphamvu ya magetsi a zipangizo, ndipo zimakhala zosavuta kubweretsa zotsatira zoopsa monga moto.Panthawiyi, kusinthana kwapansi kumatha kuthetsa mwamsanga dera lokhazikika, kuti mupewe kuwonjezereka kwa zolakwika ndi kuteteza ntchito yotetezeka ya zipangizo zamagetsi.
2. Chitetezo chaumwini
Pamene kutayikira kumachitika mu casing ya zida zamagetsi, dera grounding ndi njira yoopsa kwambiri amene angayambitse ngozi monga kuvulala munthu kapena imfa.Kusintha kwapansi kumatha kudula gawo loyambira mu nthawi yomwe magetsi akutha, kuti aletse kuti magetsi asadutse mthupi la munthu ndikuwonetsetsa chitetezo chamunthu.
3. Sungani zida
Pakukonza mzere kapena zida ndi kukonzanso, makamaka pofuna kuonetsetsa chitetezo cha ogwira ntchito, kugwirizana pakati pa zipangizo ndi mphamvu zamagetsi ziyenera kudulidwa poyamba.Panthawiyi, chosinthira chokhazikika chimatha kudula mosavuta dera lokhazikika kuti zitsimikizire chitetezo cha ogwira ntchito komanso kukonza bwino zida.
M'madera osiyanasiyana, tanthauzo la kusintha kwa magetsi otsika kudzakhala kosiyana.Komabe, ntchito zazikulu za switch ya low-voltage ndi: kusintha, chitetezo, kuzindikira kuwongolera ndikusintha.
