Kodi ndi ma Joule angati a Surge Protector? Buku Logulira Lonse

Chaka chatha ndinaphika bolodi la CNC la $3,000 chifukwa ndinagula strip ya 200-Joule pamtengo wotsika; fungo lake limandidzutsabe.

Choteteza bwino ma surge chimayamba pa ma Joules 600 pa zida zazing'ono ndipo chimadutsa ma Joules 2,000 pa ma seva kapena makina a CNC. Gwirizanitsani nambalayo ndi mtengo wa zomwe mwalumikiza.

Pansipa ndikufotokoza manambala enieni omwe mukufuna, chifukwa chake kuwerengera ndikofunikira, komanso momwe ndikupangira mizere ya chomera changa kuti muzitha kukopera pepalalo osataya bolodi kachiwiri.

N’chifukwa Chiyani Muyenera Kusamala ndi Kuwerengera kwa Joule?

Ndinayamba kunyalanyaza "Joules" ngati chinthu chopanda pake chotsatsa malonda—mpaka kukwera kamodzi kokha komwe kunachotsa ntchito ya sabata imodzi ndipo kunandiwonongera ndalama zolipirira katundu wa ndege.

Ngati Joule rating ndi yotsika kwambiri, mzerewo umafa pambuyo pogunda kamodzi ndipo makina anu amapitiriza kudya ma spikes. Sankhani nambala yoyenera ndipo mzere womwewo umayamwa kugundana kamodzi kwa zaka zambiri.

Ndisanayitanitse chidebe chilichonse cha zingwe, ndimayesa mwachangu kusanthula zoopsa: lembani chipangizo chilichonse pa benchi, lembani mtengo wake wosinthira, kenako onjezerani 20% ya chitetezo. Tebulo losavuta limenelo limandiuza ma Joules ochepa omwe ndingalandire. Ngati chitsanzo cha fakitale chili pansi pa nambala imeneyo, ndimakana zambiri—palibe imelo yachiwiri, palibe kukambirana. Ndinaphunzira movutikira kuti chidebe chotsika mtengo cha $0.50 chingachotse oda ya $50,000.

Momwe Joules Amagwirira Ntchito M'moyo Weniweni

Ganizirani za Ma Joule amakonda thanki yamafuta m'galimoto yanu. Thanki ya ma Joule 500 imatha kuyamwa "mayunitsi" 500 a mphamvu ya spike isanathe ma varistors a metal-oxide (MOVs). Thanki ya ma Joule 2,000 imakhala nthawi yayitali kuwirikiza kanayi pansi pa ma spikes omwewo. Masamu ndi olondola, kotero ndimasunga pepala lonyenga lomata pa desiki yanga:

Mtengo Wobisika wa "Just Enough" Joules

Ogula amakonda kufinya ndalama zomaliza mu BOM, koma mzere womwe umafa mutagunda kamodzi umakukakamizani kuti mung'ambe ndikusintha nthawi ina yokonza. Nthawi yopuma imeneyo ikhoza kuwononga ndalama zambiri kuposa bajeti yonse ya surge-protector. Tsopano ndikuganizira kuti mzerewo uwirikiza kawiri ma Joules owerengedwa kuti upulumuke mpaka nthawi ina yotseka.

Kodi ma Joules pa Surge Protector ndi ati?

Ndimakumbukirabe nkhope ya wogulitsa wanga pamene ndinamupempha kuti andiwonetse manambala enieni a MOV—anadziwa kuti masewerawa atha.

Ma Joule ndi mphamvu yonse yomwe phukusi la MOV lingathe kumeza lisanathe. Werengani chikwangwani cha UL, osati zilembo zazikulu zomwe zili kutsogolo, chifukwa makampani ena amawonjezera manambala a ma MOV atatu ngakhale njira imodzi yokha ikugwira ntchito.

Mkati mwa mzere uliwonse mupeza ma diski abuluu amodzi kapena angapo okwana kotala. Amenewo ndi ma MOV. Kukula kwawo ndi makulidwe ake zimakhazikitsa mphamvu, osati nyumba ya pulasitiki. Ndikufuna diski ya 14 mm ya ma Joules 1,000 ndi 20 mm ya ma Joules 2,000. Ngati fakitale itumiza ma diski a 10 mm, ndimachoka.

 Mzere wa MOV vs. Gome la Mphamvu

Chifukwa Chake Ma Rating Ena Amanama

Njira yobisika ndiyo kulumikiza ma MOV atatu a mzere kupita ku osalowerera, mzere kupita ku nthaka, osalowerera kupita ku nthaka, kenako kuwonjezera ma rating awo payokha. UL imawerengera njira yaying'ono kwambiri, kotero nambala yeniyeni ndi gawo limodzi mwa magawo atatu a mutu. Nthawi zonse ndimapempha lipoti la mayeso a UL 1449 ndikuzungulira rating ya mfundo imodzi. Ngati wogulitsa alephera, ndimachotsa mtengowo.

Kodi ma Joule angati amafunikira pazochitika zosiyanasiyana?

Ndimasunga khadi lokhala ndi laminated mu chikwama changa cha pasipoti yokhala ndi mafotokozedwe enieni a Joule pa chinthu chilichonse chomwe ndimagula; othandizira misonkho amaganiza kuti ndine wachilendo, koma mzere wanga sunatsitsidwe.

Gwiritsani ntchito 600 J pa mafoni ndi nyali, 1,000 J pa makina osindikizira, 1,500 J pa ma TV, ndi 2,000 J kapena kuposerapo pa chilichonse chomwe chimawononga ndalama zambiri kuposa malipiro anu pamwezi.

Lamulo ndi losavuta: kusintha mtengo wogawidwa ndi khumi ndi ma Joules ochepa. Chowunikira cha $200 chimafunika 200 J osachepera, koma ndimawonjezera 50% ya mutu woti ndikhale wokalamba. Njira yachidule imeneyo sinandilepheretsepo.

Pepala Lonyenga la Zochitika

Milandu ya Mphepete Anthu Amaiwala

Ma drive a mota amabweza ma spikes a EMF omwe amatha kuwirikiza kawiri mphamvu yamagetsi. Nthawi zonse ndimawirikiza kawiri mphamvu ya Joule pamene katunduyo ndi woyambitsa. Ma charger a batri ndi msampha wina—amaoneka ngati opanda vuto, koma chosinthira cha switched-mode chimatha kubweza 800 J mumzere pamene relay ikutsegulidwa. Ndataya oscilloscope ya $900 mwanjira imeneyo; tsopano benchi iliyonse yoyesera imapeza osachepera 1,500 J.

Chifukwa Chake Kuwerengera Kwambiri kwa Joule N'kofunika Kwambiri pa Zipangizo Zanu Zamagetsi

Tsiku limene mzere wanga wosankha ndi kuyika unayima, ndinali ndi anthu 12 omwe anali kuyimirira osagwira ntchito pamtengo wa $80 pa ola limodzi—$960 pa ola limodzi chifukwa mzere wa 400-Joule unasiya.

Mizere ya High Joule imagwira ntchito ngati siponji yayikulu; imamwa ma hits obwerezabwereza kotero kuti makina anu apitirize kugwira ntchito ndipo zopempha zanu za chitsimikizo zimakhala zero.

Kukwera kulikonse kumawononga MOV pang'ono. Chipangizo cha 500-Joule chimafa pambuyo poti chagunda 400-Joule, koma chipangizo cha 2,000-Joule chimagunda mwamphamvu ma strips anayi omwewo. Izi zikutanthauza kuti mumasintha ma strips nthawi yotsatira PM, osati panthawi yoitana mwadzidzidzi.

Mtengo Wonse wa Tebulo la Eni ake

Masamu ndi ovuta kwambiri: kusunga $1.60 pasadakhale kungawononge ndalama zambiri pambuyo pake. CFO wanga potsiriza anasiya kukangana nditamuwonetsa pepala ili.

Chithunzi Cholephera Padziko Lonse Chenicheni Chimene Ndisunga

Ndinaika chidutswa cha 600-Joule chomwe chinaphulika pa bolodi la zilengezo pafupi ndi wotchi ya nthawi. MOV inatseguka ngati cookie ndipo inapsa pulasitiki. Pafupi ndi icho pali chidutswa cha 3,000-Joule chomwe chinagundanso mphezi yomweyo ndipo chinayesedwabe bwino. Sipanafunike kulankhula; chithunzicho chimaphunzitsa.

Kodi ma Joules angati ndi Chitetezo Chabwino cha Surge?

Ndimauza wogula aliyense watsopano chiganizo chomwecho: "Chabwino chimayamba pa ma Joules 1,000 ndipo chimakwera mpaka mtengo utakhala wotsika kuposa nthawi yopuma."

Choteteza bwino ma surge chimakhala ndi ma Joules osachepera 1,000, satifiketi ya UL 1449, ndi voltage yotsekera pansi pa 400 V. Chilichonse chotsika ndi power strip, osati chitetezo.

Ndimalemba mndandanda womaliza ndisanasainire nambala ya fayilo ya PO: UL, single-point Joule rating, 14 mm MOV minimum, komanso mayeso a short-circuit a 100 kA. Ngati fakitale iwona zonse zinayi, mzerewo umapeza logo yanga ndi chitsimikizo cha zaka zisanu.

Mndandanda Wofufuza Wogula Mwachangu

- [ ] Fayilo ya UL 1449 4th Edition yosindikizidwa

- [] Ma Joules osindikizidwa mbali ya MOV, osati bokosi lokha

- [ ] Voliyumu yolumikizira ≤ 400 V

- [ ] Nthawi yoyankha

- [] Nyumba yosazima moto V0 rating

Ndimaika izi mu chikwatu choyendera ndikuzipereka kwa munthu wa QC yemwe amapita ku Wenzhou paulendo uliwonse woyamba. Kudumpha chinthu chimodzi kunanditengera chidebe cha mamita 20 chomwe ndinabweza kuchokera ku Hamburg—sichinabwerenso.

Mapeto

Sankhani Joule yomwe bajeti yanu imalola, yesani MOV nokha, ndipo gonani monga momwe ndimachitira—podziwa kuti mzerewo udzamvekabe pambuyo pa mphepo yamkuntho yotsatira.
