Liper, kambani inotungamira mukupa mhinduro dzemwenje itsva, nhasi uno inosimbisa kukosha kwekudzivirira kukwira kwemagetsi mumasisitimu emwenje emudzimba neemabhizinesi. Kukwira kwemagetsi, kazhinji kusinganzwisiswe, kunokanganisa hupenyu hwemwenje yemazuva ano uye mashandiro ayo.
Chii chinonzi Power Surge?
Kukwira kwesimba remagetsi kunoitika kamwe kamwe, kwenguva pfupi, kupfuura kuyerera kwakajairika (semuenzaniso, 100V/240V AC). Kukwira uku, kunogara mamiriyoni esekondi, kunogona kubva pa:
1.Mheni Inorova: Kurova zvakananga kana kurova kuri pedyo zvichikonzera kukwira kwemagetsi.
2.Mashandiro eGrid: Kuchinja mashandisirwo emagetsi, kuvhura capacitor bank, kana kubvisa ma fake.
3.Zvinyorwa zvemukati: Mamota makuru (maelevator, muchina wemagetsi) ari kufamba netsoka mukati mechivako.
Dambudziko Rakavanzika Kumwenje Wako
Kukwira kwemvura kunokonzera njodzi huru kana kuti kukuvara kwakawanda:
1.Kukundikana Pakarepo: Kutsva kamwe kamwe kwemadhiraivha e LED, ma controllers, kana magetsi.
2.Kushanda Kwakashata: Kukuvara zvishoma nezvishoma kunopfupisa hupenyu hwezuva, zvichikonzera kudzima, kuchinja kwemavara, kana kudzikira kwekupenya.
3.Kukuvadzwa kweSisitimu Yekudzora: Kukanganisa ma network emwenje akangwara, masensa, uye masisitimu ekudzima chiedza.
4.Njodzi dzeKuchengetedzeka: Njodzi dzinogona kuitika dzemoto dzinobva muzvinhu zvakakuvara.
5.Nguva Yokuzorora Inodhura & Kutsiva: Mari yekugadzirisa isina kurongwa uye yekutsiva michina.
Mushure mekuverenga ruzivo urwu, pamwe uri kufunga kuti ungadzivisa sei matambudziko aya...Uye kutaura chokwadi, International Electrotechnical Commission (IEC) inoisa zviyero zvakajeka zvekudzivirira kukwira kwesimba muzvishandiso zvemwenje kuburikidzaIEC 60598-1uye mitemo chaiyo yekushanda yakaita seIEC 61547Zvinodiwa zvikuru zvinosanganisira:
1.Mwenje yemukati: Inowanzo dikanwa kuti itsungirire kukwira kweLevel 2 (kunowanzo wanikwa muzvivakwa):
·Mutsetse-ku-Mutsetse: 1 kV
·Kuenda kuPasi (Pasi): 2 kV
2.Mwenje yekunze: Kusangana nenjodzi dzakakura (mheni, kumhanya kwenguva refu kwetambo), zvinoda dziviriro yeLevel 3 kana 4:
·Kubva pamutsetse kuenda pamutsetse: 2 kV kana 4 kV
·Kuenda kuPasi (Pasi): 4 kV kana 6 kV – Zvakakosha pakugadzira zvinhu pamatanda, miganhu yezvivakwa, kana nzvimbo dzakasiyana-siyana.
Chii chinoitwa naLiper kuti mwenje ive yakachengeteka uye ine hupenyu hurefu?
Liper ine hanya nekuchengetedzeka nguva dzese, saka mainjiniya edu anonyanya kutarisisa kuwedzera michina yekudzivirira kukwira kwemvura uye mapurofesa edu achaedza mwenje yedu mukamuri rekuyedza reEMC kuona kuti mwenje yedu ine mwero wepamusoro wekuwedzera kwemvura.
1. Wedzera zvimwezvishandiso zvekudzivirira kukwira kwemvurapanguva yekugadzira bhodhi rePCB.
·Varistor: clamp voltage nekushandura surge current.
·Chinodzivirira fuse: kurumidza kuputitsa kudzivirira zviitiko zvakakomba zvekuchengetedza (zvakaita semoto).
·Kudzvinyirira Kwemagetsi Kwenguva Pfupi (TVS): mhinduro inokurumidza zvikuru, ichidzivirira maIC anonzwa muvatyairi/vanodzora. Kubata simba shoma.
·Common mode inductors: kuita kuti magetsi awedzere kamwe kamwe asi anowedzera zvishoma nezvishoma uye anotora simba rinobva rauya kamwe kamwe. (Zvinodiwa mumwenje yemumugwagwa, mwenje yemvura uye mwenje yemumugwagwa)
(usati washandisa common mode inductor)
(mushure mekushandisa common mode inductor)
2. Edza mwenje murabhoritari yedu yehunyanzvi
·Jenareta yekuwedzera: mwero wekuyedza wakakwira kupfuura mwero weIEC. Pamwenje yemumugwagwa, tinogona kusvika 10kV mushure mekuwedzera zvinodzivirira mheni.
·Imba yekuyedza yeEMC: edzai kugona kwekudzivirira kukanganiswa uye edzai kana mwenje yedu ichizokanganisa mimwe midziyo kana kwete. Bvunzo iyi iri pasi peCB standard.
Mushure mezviito izvi, unogona kuvimba nekushandisa marambi edu pachirongwa ichi! Liper, rudzi rwaunogona kuvimba narwo nekusingaperi!
