Liper, kampani yotsogola yopereka njira zatsopano zowunikira, lero ikugogomezera kufunika koteteza mafunde m'magalimoto m'nyumba ndi m'mabizinesi. Kuwonjezeka kwa magetsi, komwe nthawi zambiri sikumvetsetsedwa bwino, kumabweretsa chiopsezo chachikulu pa moyo wautali komanso magwiridwe antchito a magetsi amakono.
Kodi Kuthamanga kwa Mphamvu ndi Chiyani?
Kukwera kwa mphamvu yamagetsi ndi kukwera kwadzidzidzi kwa mphamvu yamagetsi komwe kumapitirira kuchuluka kwa mphamvu yamagetsi (monga 100V/240V AC). Kukwera kumeneku, komwe kumakhalapo kwa mphindi imodzi, kungachokere ku:
1.Kugunda kwa Mphezi: Kugunda mwachindunji kapena kugunda kwapafupi komwe kumayambitsa kukwera kwa mawaya amagetsi.
2.Ntchito za Gridi: Kusintha kwa zida zamagetsi, kuyambitsa capacitor bank, kapena kuchotsa zolakwika.
3.Magwero amkati: Ma injini akuluakulu (ma elevator, makina amagetsi) akuyendetsa/kuzima mkati mwa nyumba.
Chiwopsezo Chobisika pa Kuwala Kwanu
Kuphulika kwa madzi kumabweretsa kuwonongeka kwakukulu kapena kowonjezereka:
1.Kulephera Kwachangu: Kutenthedwa mwadzidzidzi kwa madalaivala a LED, owongolera, kapena magetsi.
2.Kugwira Ntchito Koyipa: Kuwonongeka pang'onopang'ono komwe kumafupikitsa nthawi ya moyo, zomwe zimayambitsa kuthwanima, kusintha kwa mitundu, kapena kuchepa kwa kuwala.
3.Kuwonongeka kwa Dongosolo Lolamulira: Kuwononga ma network anzeru a magetsi, masensa, ndi makina oziziritsa kuwala.
4.Zoopsa za Chitetezo: Ziwopsezo za moto zomwe zingachitike chifukwa cha zinthu zowonongeka.
5.Nthawi Yopuma Yokwera Mtengo & Zosintha: Ndalama zosakonzedwa zosamalira ndi kusintha zida.
Mukawerenga izi, mwina mukudabwa momwe mungapewere mavutowa...Ndipo kwenikweni, International Electrotechnical Commission (IEC) imayika miyezo yomveka bwino ya chitetezo chamthupi m'mafakitale a magetsi kudzera muIEC 60598-1ndi miyezo yeniyeni yogwirira ntchito mongaIEC 61547Zofunikira zazikulu ndi izi:
1.Magetsi amkati: Kawirikawiri amafunika kupirira kukwera kwa Level 2 (kofala m'nyumba):
·Kuchokera pa Mzere: 1 kV
·Kupita ku Dziko Lapansi (Pansi): 2 kV
2.Kuwala Kwakunja: Kukumana ndi zoopsa zambiri (mphezi, kugwiritsa ntchito chingwe nthawi yayitali), kumafuna chitetezo cha Level 3 kapena 4:
·Kuchokera pa Mzere kupita pa Mzere: 2 kV kapena 4 kV
·Kupita ku Dziko Lapansi (Pansi): 4 kV kapena 6 kV – Chofunika kwambiri pa zipangizo zomangira pamitengo, m'mbali mwa nyumba, kapena m'malo okongola.
Kodi Liper amachita chiyani kuti magetsi akhale otetezeka komanso okhala ndi moyo wautali?
Liper amasamala za chitetezo nthawi zonse, kotero mainjiniya athu amayang'ana kwambiri pakuwonjezera zida zotetezera mafunde ndipo aphunzitsi athu adzayesa magetsi athu mchipinda choyesera cha EMC kuti atsimikizire kuti magetsi athu ali ndi mulingo wapamwamba wa mafunde.
1. Onjezani zinazipangizo zotetezera kugwedezeka kwa mpweyapamene akupanga bolodi la PCB.
·Varistors: mphamvu yamagetsi yolumikizira mphamvu pogwiritsa ntchito mphamvu yamagetsi yosinthira mphamvu.
·Choletsa fuse: phulitsani mwachangu kuti mupewe ngozi zoopsa kwambiri (monga moto).
·Kuchepetsa Mphamvu ya Voltage Yaching'ono (TVS): yankho lachangu kwambiri, kuteteza ma IC osavuta kugwiritsa ntchito mu madalaivala/owongolera. Kuchepetsa mphamvu yogwiritsira ntchito.
·Ma inductors a Common mode: mphamvu yamagetsi siingakwere mwadzidzidzi koma imakwera pang'onopang'ono ndikuyamwa mphamvu yadzidzidzi. (yofunikira pa magetsi a pamsewu, magetsi amagetsi ndi magetsi a highbay)
(musanayambe kugwiritsa ntchito inductor ya common mode)
(mutagwiritsa ntchito inductor ya common mode)
2. Yesani magetsi mu labotale yathu yaukadaulo
·Jenereta yopangira mafunde: muyezo wa mayesowo ndi wapamwamba kuposa muyezo wa IEC. Pa magetsi a mumsewu, tikhoza kufika pa 10kV titawonjezera zoletsa mphezi.
·Chipinda choyesera cha EMC: yesani mphamvu yoletsa kusokonezedwa ndi kuyesa ngati magetsi athu angakhudze zida zina kapena ayi. Mayesowa ndi otsatira muyezo wa CB.
Mukachita izi, mutha kudalira kugwiritsa ntchito magetsi athu pa ntchitoyi! Liper, kampani yomwe mungadalire kwamuyaya!
