Liper, mupi anotungamira wezvigadziriso zvemwenje zvigadziriso, nhasi anosimbisa kukosha kwakakosha kwekuchengetedzwa kwekuvhiya mune zvese zvekugara uye zvekutengesa masisitimu emwenje. Kuwedzerwa kwemagetsi, kazhinji kusanzwisiswa, kunopa ngozi huru kune hupenyu hurefu uye kushanda kwechiedza chemazuva ano.
Chii chinonzi Power Surge?
Kuwedzera kwemagetsi kungoerekana kwaitika, kupfupi mumagetsi emagetsi anodarika mwero wekuyerera (semuenzaniso, 100V/240V AC). Aya maspikes, anogara mamirioni esekondi, anogona kubva:
1.Mheni Inorova: Kurova kwakananga kana kurova kwepedyo kuchikonzera masurges mumatambo emagetsi.
2.Grid Operations: Utility switching, capacitor bank activations, kana kukanganisa kuchenesa.
3.Zvinyorwa zvemukati: Mahombe emotor (elevator, magetsi muchina) kuchovha pa/kudzima mukati mechivako.
Kutyisidzira Kwakavanzika kune Mwenje Yako
Kuvhiya kunokonzera njodzi kana kuwanda kukuvadza:
1.Kukundikana Pakarepo: Kamwe-kamwe kutsva kwevatyairi ve LED, vanodzora, kana magetsi.
2.Degraded Performance: Kukuvadza zvishoma nezvishoma kupfupisa hupenyu, zvichikonzera kupenya, kuchinja kwemavara, kana kuderera kupenya.
3.Kudzora Kukuvadza KweSistimu: Inoremara smart lighting network, sensors, uye dimming masisitimu.
4.Njodzi Dzakachengeteka: Njodzi dzinogona kuitika dzemoto kubva kune zvakakuvadzwa zvikamu.
5.Inodhura Downtime & Replacements: Kusarongeka kwekugadzirisa uye kugadzirisa mari yekutsiva.
Mushure mekuverenga ruzivo urwu, pamwe urikunetseka kuti ungadzivise sei nyaya idzi ... Uye kutaura zvazviri, The International Electrotechnical Commission (IEC) inoisa mabhenji akajeka ekuvhiya kusadzivirirwa mumagetsi ekuvhenekesa kuburikidza.IEC 60598-1uye chaiwo maitiro ekuita sengeIEC 61547. Zvinodiwa zvikuru zvinosanganisira:
1.Mwenje wemukati: Kazhinji inodiwa kumira Level 2 surges (yakajairwa muzvivakwa):
·Mutsara-ku-Mutsara:1 kV
·Mutsara-kune-Pasi (Pasi): 2 kV
2.Outdoor Mwenje: Inoratidzirwa kune njodzi dzakakwirira (mheni, tambo refu inomhanya), inoda Level 3 kana 4 kusadzivirirwa:
·Mutsetse-ku-Mutsara: 2 kV kana 4 kV
· Line-to-Earth (Ground):4 kV kana 6 kV – Yakakosha pazvimisikidzo pamapango, mativi ekuvaka, kana nzvimbo.
Chii chinoitwa naLiper kuti ave nechokwadi chekuti mwenje inogona kuve yakachengeteka uye nehupenyu hurefu?
Liper ine hanya nezvekuchengetedza nguva dzese, saka mainjiniya edu anotarisisa kuwedzera michina yekudzivirira yekuvhiya uye mapurofesa edu anoedza mwenje yedu muEMC test room kuona kuti mwenje yedu ine mwero wepamusoro wekuvhiya.
1.Wedzera zvimwesurge kudzivirira zvishandisouchigadzira bhodhi rePCB.
·Varistor: clamp voltage nekutsausa surge ikozvino.
·Fuse resistor: kurumidza kuvhuvhuta kudzivirira zviitiko zvakakomba zvekuchengetedza (senge moto).
·Transient Voltage Suppression (TVS): mhinduro inokurumidza, inodzivirira ICs inonzwisisika mune vatyairi / vatongi. Lower simba kubata.
·Common mode inductors: ita kuti ikozvino haigone kuwedzera kamwe kamwe asi wedzera zvishoma nezvishoma uye kutora simba rinokurumidza. (zvinoda mu streetlight, floodlights uye highbay lights)
(usati washandisa common mode inductor)
(mushure mekushandisa common mode inductor)
2.Edza mwenje murabhoritari yedu yehunyanzvi
·Surge jenareta: chiyero chebvunzo chakakwira kupfuura IEC standard. Kumagetsi emumugwagwa, tinogona kusvika 10kV mushure mekuwedzera zvinosunga mheni.
·EMC test room: edza anti-kupindira kugona uye edza kana mwenje yedu ichizokanganisa imwe mudziyo kana kwete. Muedzo uyu uri pasi peCB standard.
Mushure mezviito izvi, unogona kuvimba nekushandisa mwenje yedu kupurojekiti! Liper, chiratidzo chaunogona kuvimba nekusingaperi!
