KumvetsetsaOteteza OthamangaChitetezo Chamagetsi Chofunika Kwambiri
Mu dziko la digito lomwe likukulirakulira, zipangizo zamagetsi zakhala gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku, ndipo kufunika koteteza zipangizozi sikunganyalanyazidwe. Njira imodzi yothandiza kwambiri yotetezera zipangizo zamagetsi ndi kugwiritsa ntchito chida choteteza ma surge. Nkhaniyi ifotokoza bwino zomwe zida zoteteza ma surge zilili, momwe zimagwirira ntchito, komanso chifukwa chake zili zofunika kwambiri m'nyumba ndi m'maofesi.
Kodi chitetezo cha surge ndi chiyani?
Choteteza ma surge ndi chipangizo chomwe chimagwiritsidwa ntchito kuteteza zida zamagetsi ku ma voltage spikes. Ma spikes amenewa amatha kuchitika pazifukwa zosiyanasiyana, kuphatikizapo kugunda kwa mphezi, kuzimitsa magetsi, komanso kuyatsa mwadzidzidzi kwa zida zazikulu. Pamene magetsi apitirira malire enaake, choteteza ma surge chimachotsa magetsi ochuluka kuchoka pa zida zolumikizidwa, zomwe zimaletsa kuwonongeka.
Kodi chitetezo cha surge chimagwira ntchito bwanji?
Zoteteza ma surge zimagwiritsa ntchito chinthu chotchedwa metal oxide varistor (MOV). MOV ndi semiconductor yomwe kukana kwake kumasintha kutengera kuchuluka kwa magetsi. Munthawi yabwinobwino, MOV imalola kuti magetsi aziyenda momasuka kuzipangizo zanu. Komabe, pamene ma surge achitika, MOV imazindikira ma overvoltage ndikuyitumiza pansi, zomwe zimathandiza kuti zipangizo zanu zisawonongeke.
Zoteteza zambiri za surge zimabweranso ndi zinthu zina, monga ma circuit breaker (omwe amadula magetsi ngati magetsi akwera kwambiri) ndi magetsi owonetsa ngati chipangizocho chikugwira ntchito bwino). Mitundu ina yapamwamba imakhala ndi zinthu monga ma USB ports ochajira mafoni ndi ma Wi-Fi routers omangidwa mkati.
N’chifukwa chiyani zoteteza ku mafunde n’zofunika?
1. Zimateteza ku kukwera kwa magetsi: Ntchito yaikulu ya choteteza mafunde ndikuteteza zipangizo zamagetsi ku kukwera kwa magetsi. Popanda chitetezo ichi, zipangizo monga makompyuta, ma TV, ndi zipangizo zapakhomo zimatha kuwonongeka kwambiri, zomwe zimapangitsa kuti pakhale kukonza kapena kusintha zinthu zina zodula.
2. Yankho Lotsika Mtengo: Kuyika ndalama mu chida choteteza ma surge ndi njira yotsika mtengo yotetezera zida zanu zamagetsi zamtengo wapatali. Mtengo wa chida choteteza ma surge ndi wochepa poyerekeza ndi mtengo womwe ungagulitsidwe posintha chipangizo chomwe chawonongeka.
3. Mtendere wa Mumtima: Kudziwa kuti zipangizo zanu zatetezedwa ku mphamvu zosayembekezereka kungakupatseni mtendere wa mumtima. Izi ndizofunikira kwambiri kwa iwo omwe amadalira zipangizo zamagetsi pantchito kapena pa ntchito zawo.
4. Kutalikitsa moyo wa zipangizo zanu: Poteteza ku kukwera kwa magetsi, zoteteza ma surge zingathandize kutalikitsa moyo wa zipangizo zanu zamagetsi. Izi zikutanthauza kuti mutha kugwiritsa ntchito zipangizo zanu kwa nthawi yayitali popanda kuda nkhawa kuti zalephera msanga.
Kusankha Woteteza Woyenera wa Surge
Posankha choteteza ma surge, ganizirani zinthu zotsatirazi:
- Joule Rating: Kuwunikaku kukuwonetsa kuchuluka kwa mphamvu zomwe chitetezo cha surge chingatenge chisanathe. Kuwunika kwakukulu kwa joule, chitetezo chimakhala chabwino.
- Chiwerengero cha malo otulutsira magetsi: Onetsetsani kuti choteteza ma surge chili ndi malo okwanira otulutsira magetsi pazida zanu zonse. Mitundu ina imaperekanso malo otulutsira magetsi otalikirana kuti agwirizane ndi ma plug akuluakulu.
- Nthawi Yoyankha: Yang'anani choteteza ma surge chomwe chili ndi nthawi yoyankha mwachangu kuti muwonetsetse chitetezo nthawi yomweyo panthawi ya ma surge.
- Chitsimikizo: Zoteteza zambiri za surge zimabwera ndi zitsimikizo zomwe zimaphimba zida zolumikizidwa. Izi zingakupatseni mtendere wamumtima wowonjezereka.
Pomaliza
Pomaliza, zoteteza ma surge ndi zida zofunika kwambiri zomwe zimathandiza kwambiri kuteteza zipangizo zathu zamagetsi ku kukwera kwa magetsi. Pomvetsetsa momwe zimagwirira ntchito komanso ubwino wake, ogula amatha kupanga chisankho chodziwikiratu pankhani yoteteza zamagetsi zawo zamtengo wapatali. Kaya kunyumba kapena kuofesi, kuyika ndalama mu surge protector yapamwamba ndi chisankho chanzeru chomwe chingakupulumutseni nthawi, ndalama, ndi nkhawa mtsogolo.
