Kusankhidwa kwa switch yoteteza kutayikira kwa bokosi limodzi, mabokosi awiri am'magulu awiri ndi mabokosi atatu ogawa

Ma switch ndi odziwika bwino kwa ife ngati akatswiri amagetsi.Koma kodi mukugwiritsa ntchito masiwichi olondola ndi zosankha?

Tn-s ndimagetsinjira yopangira malo.Pali magawo atatu ogawa mphamvu ndi magawo awiri achitetezo.Makina amodzi, chipata chimodzi, kutayikira kumodzi ndi bokosi limodzi ndizofunikira.Mzere wa PE ndi woletsedwa kukhazikitsa masiwichi, ndikoletsedwa kulumikiza zida zamagetsi zingapo pamwamba pa switch.Ndipo danga pakati pa bokosi loyamba, bokosi lachiwiri ndi lapamwamba ndi mamita 30.

Tikasankha kusintha kwa nduna yogawa magawo atatu, tiyenera kulabadira vuto loterolo, ndiye kuti, pakukhazikitsa chitetezo chovotera kutayikira kwa magawo awiri akutayikira pano komanso ovotera kutayikira nthawi iyenera kukhala yololera. pewani zochitika zodumphadumpha.

Nthawi zambiri tikayika magawo apamwamba pakusankha atatuwa ndikukhazikitsachitetezo chitetezomu bokosi yogawa, kugawa okwana kutayikira mlingo wa kutayikira mtetezi kanthu ovotera kutayikira panopa ndi zosakwana kapena wofanana ndi 150 ma zochita nthawi si wamkulu kuposa 0.2 masekondi, yachiwiri ovetere kutayikira zochita panopa si oposa 75 ma, oveteredwa. kutayikira kanthu nthawi si wamkulu kuposa 0.1 masekondi, The kutayikira ntchito panopa mu bokosi lophimba si upambana 30 ma, ndipo oveteredwa ntchito nthawi si upambana 0.1 masekondi.M'malo achinyezi, kutayikira komwe kukuchitika m'malo oyendetsa bwino sikupitilira 15 ma, ndipo nthawiyo sipitilira masekondi 0.1.

Tikamakumana ndi mavuto chifukwa chiyani tiyenera kukakamiza kugwiritsa ntchito ma transparent circuit breakers ndi ma leakage circuit breakers.Pambuyo pake, ndinayang'ana chidziwitso chofunikira ndipo ndinaphunzira kuti tiyenera kusiya mfundo zodziwikiratu zolumphira pamzere tikalandira magetsi pamalopo, kuti tipewe vuto kuti chingwecho sichimachotsedwa ntchito.Kugwiritsa ntchito zotchingira zowonekera bwino komanso zoteteza kutayikira zimatha kuyang'ana mwachidziwitso ngati chingwe kapena switchyo yalumikizidwa, kuti mupewe ngozi yakugwedezeka kwamagetsi.

Palinso kugwiritsa ntchito a3P wozungulira derachifukwa chake komanso kumapeto kwake kukhazikitsa 3P + Nleakage circuit breaker.Ntchito ya wophwanyira dera ndikuyatsa ndi kuzimitsa ndikudzaza, chitetezo chachifupi chozungulira.Chowotcha chowotchera chotayikira chimakhala ndi ntchito yoteteza kutayikira kuphatikiza pazigawo zazifupi zomwe zimayatsidwa ndikuzimitsa.Chifukwa cha matope ambiri ndi madzi pamalopo, malo omangapo ndi ovuta ndipo kuyika kwa chitetezo chotayikira kwakhala njira yofunika kwambiri yotetezera.
