Liper, wotsogola wotsogolera njira zowunikira zowunikira, lero akugogomezera kufunikira kofunikira kwa chitetezo chachitetezo m'nyumba zonse zowunikira komanso zamalonda. Kuwomba kwamphamvu, komwe nthawi zambiri sikumamveka bwino, kumabweretsa chiwopsezo chachikulu ku moyo wautali komanso magwiridwe antchito a zowunikira zamakono.
Kodi Power Surge ndi chiyani?
Kukwera kwamagetsi ndi kukwera kwadzidzidzi, kwachidule kwa voteji yamagetsi kuposa momwe amayendera (monga 100V/240V AC). Ma spikes awa, opitilira miliyoni miliyoni pamphindikati, amatha kuchokera ku:
1.Kugunda kwa Mphezi: Kumenyedwa kwachindunji kapena kumenyedwa kwapafupi komwe kumapangitsa kuti makwerero apite mu mizere yamagetsi.
2.Ntchito za Gridi: Kusintha kwa ntchito, kutsegulira kwa banki ya capacitor, kapena kukonza zolakwika.
3.Magwero Amkati: Ma motors akuluakulu (ma elevator, makina amagetsi) akuyendetsa / kuzimitsa mkati mwa nyumba.
Chiwopsezo Chobisika pa Kuunikira Kwanu
Matendawa amayambitsa kuwonongeka kwakukulu kapena kowonjezereka:
1.Kulephera Mwamsanga: Kutopa kwadzidzidzi kwa madalaivala a LED, owongolera, kapena magetsi.
2.Kuchita Zowonongeka: Kuwonongeka kwapang'onopang'ono kufupikitsa moyo, kuchititsa kutsetsereka, kusintha kwamitundu, kapena kuchepa kwa kuwala.
3.Control System Kuwonongeka: Kupundula maunetiweki owunikira mwanzeru, masensa, ndi makina ocheperako.
4.Zowopsa Zachitetezo: Zowopsa zomwe zingachitike pamoto kuchokera kuzinthu zowonongeka.
5.Nthawi Yotsika Yotsika & Zosintha: Kukonza kosakonzekera ndi ndalama zosinthira.
Pambuyo powerenga izi, mwina mukudabwa momwe mungapewere izi ... Ndipo m'malo mwake, International Electrotechnical Commission (IEC) imayika zizindikiro zomveka bwino za chitetezo cham'thupi pamagetsi owunikira.IEC 60598-1ndi miyezo yogwira ntchito ngatiIEC 61547. Zofunikira zazikulu ndi izi:
1.Magetsi amkati: Zomwe zimafunikira kuti mupirire kuthamanga kwa Level 2 (zofala mnyumba):
Mzere-mzere: 1 kV
· Line-to-Earth (Pansi): 2 kV
2.Kuwala Kwakunja: Kuwonetsedwa paziwopsezo zazikulu (mphezi, zingwe zazitali), zomwe zimafunikira chitetezo cha Level 3 kapena 4:
· Line-to-Line: 2 kV kapena 4 kV
· Line-to-Earth (Ground): 4 kV kapena 6 kV – Ndikofunikira kwambiri pamipangidwe yamitengo, malo ozungulira, kapena malo.
Kodi Liper amachita chiyani kuti awonetsetse kuti magetsi azikhala otetezeka komanso okhala ndi moyo wautali?
Liper amasamala za chitetezo nthawi zonse, kotero mainjiniya athu amayang'ana kwambiri kuwonjezera zida zoteteza maopaleshoni ndipo mapulofesa athu adzayesa magetsi athu muchipinda choyesera cha EMC kuti awonetsetse kuti magetsi athu ali ndi mulingo wapamwamba kwambiri wa opareshoni.
1.Onjezani zinazida zodzitetezerapopanga bolodi la PCB.
·Varistors: Kuchepetsa mphamvu yamagetsi potembenuza mawotchi apakali pano.
·Fuse resistor: kuwomba mwachangu kuti mupewe ngozi zowopsa (monga moto).
·Transient Voltage Suppression (TVS): kuyankha mwachangu kwambiri, kuteteza ma IC tcheru mu madalaivala/owongolera. Kugwiritsa ntchito mphamvu zochepa.
·Common mode inductors: pangitsa kuti magetsi asachuluke mwadzidzidzi koma onjezerani pang'onopang'ono ndi kuyamwa mphamvu mwadzidzidzi. (zofunika mu streetlight, floodlights ndi highbay magetsi
(Musanagwiritse ntchito common mode inductor)
(pambuyo pogwiritsira ntchito common mode inductor)
2.Yesani magetsi mu labotale yathu yaukadaulo
·Jenereta yamagetsi: muyezo wa mayesowo ndi wapamwamba kuposa muyezo wa IEC. Kwa magetsi apamsewu, titha kufikira 10kV mutawonjezera zotsekera mphezi.
·Chipinda choyesera cha EMC: yesani mphamvu yoletsa kusokoneza ndikuyesa ngati magetsi athu angakhudze zida zina kapena ayi. Mayesowa ali pansi pa CB standard.
Pambuyo pa izi, mutha kudalira kugwiritsa ntchito magetsi athu pantchitoyi! Liper, mtundu womwe ungadalire mpaka kalekale!
