Ingabe Abavikeli Bokukhuphuka Bayaba Mbi?

Ngake ngalahlekelwa yisilawuli se-CNC esingu-$3,000 ngoba umugqa “omusha” waphela buthule. Lokho kuhlaba kwangifundisa ukungabaza yonke i-LED ekhanyayo.

Yebo, izivikeli zokuqhuma iyaguga. Ama-MOV awo ayaqhekeka, amunce amandla amancane, bese ekugcineni evumela i-spike elandelayo iqonde ngqo egiyeni lakho.Ngilinganisa lokhu kubola elabhorethri yami yaseWenzhou njalo ngeviki.

Qhubeka ufunda futhi ngizokukhombisa izimpawu eziqondile, izinombolo, kanye nemithetho yokufaka esikhundleni esiyisebenzisayo lapho sithumela ama-container angamafidi angu-40 eBerlin naseBirmingham.

Kanjani Abavikeli Bokukhuphuka Umsebenzi?

Ngisakhumbula isikhathi sokuqala ebona ngaso I-MOV ukuvunguza njengesiqhumane esincane ngaphakathi kwebhokisi lepulasitiki elimhlophe. Leso sithombe sangiqinisekisa ukuthi lezi zingxenye zingamaqhawe aphila isikhathi esifushane.

A isivikelo sokwanda iphonsa ama-volts engeziwe kuma-varistor e-metal-oxide. Ama-varistor amunca ukushaya, kodwa ukushaya ngakunye kuyawadla aze aqhekeke futhi ayeke ukuqhuba.Ngikuvivinya lokhu efektri yethu engamamitha-skwele angu-2,000.

Yini Engaphakathi Kwesiqeshana?

Iningi labathengi libona kuphela inkinobho ekhazimulayo kanye nesibani esiluhlaza. Ngivula ibhokisi bese ngibabonisa izingxenye ezintathu:

Mangaki ama-Joule Ongawasebenzisa?

Ama-Joules afana nemali esesikhwameni. Iyunithi engu-1,000 J ingathatha i-hit eyodwa engu-1,000 J noma i-hit eziyishumi ezingu-100 J. Ngibhale ama-surges esitshalweni saseHamburg izinyanga eziyisithupha. Ithebula elingezansi libonisa ukuthi yini ethinte imigqa yawo:

NgoMashi umvikeli wayesesele no-445 J kuphela. Ngaleso sikhathi kwakuzoba kungenalutho ngaphambi kwehlobo.

Kungani Ukukhanya Okuluhlaza Kulele

I-LED ikutshela kuphela ukuthi i-fuse iyaphila. I-MOV ingahlukaniswa phakathi bese ukukhanya kusakhanya. Ngicela abathengi ukuthi bahlole nge-outlet tester elula kanye ne-load bank kanye ngonyaka. Uma ukwehla kwe-voltage kukhuphuka ngaphezu kuka-5%, i-MOV ayisekho.

Izimpawu Zokuthi Umvikeli Wakho Wokukhuphuka Angase Ahluleke

Ngonyaka odlule iklayenti laseFrance lathumela inqwaba eyayibukeka iphelele ngaphandle. Ngaphakathi, imizila yokusha ensundu yayihamba njengemigwaqo emincane. Lelo phunga lepulasitiki ethosiwe liyisixwayiso engingalokothi ngisinake.

Isivikelo sakho sokugeleza siyahluleka uma ikesi lifudumele, i-LED ikhanya, noma uzwa umsindo omncane. Ngishintsha noma yimuphi umugqa obonisa lezi zimpawu.Ngibheka wonke amabhokisi ethu aphumayo ukuze ngithole lezi zinkomba.

Zizwe Igobolondo

Ngemva kwehora elilodwa lokulayisha, izinga lokushisa lobuso kufanele lihlale ngaphansi kuka-40°C. Ngisebenzisa isibhamu se-IR esingu-$20 futhi ngiskena indawo ngayinye yokukhipha. Indawo eshisayo isho ukuthi i-MOV ivuza ugesi futhi iguqula amandla abe ukushisa.

Ukuhlolwa Kokuhogela

Ibhodi elinempilo linuka njengepulasitiki nensimbi. I-MOV efayo ikhipha iphunga elimnandi nelibukhali. Ngiqeqesha ithimba lethu le-QC ukuthi liqaphele lokhu ngaphansi kwemizuzwana emihlanu ocingweni.

Ishidi Lokukhohlisa le-LED

Sakha itafula elincane esilinamathisela ngaphakathi kwebhokisi ngalinye lokuthumela impahla kwamanye amazwe:

Abavikeli Bokukhuphuka Bahlala Isikhathi Eside Kangakanani?

Ngigcina i-rack yamasampula esebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngosuku, izinsuku eziyi-7 ngosuku, ku-voltage elinganisiwe engu-1.5×. Ngemva kwezinyanga ezingama-36, ingxenye yama-MOV yehle ngaphansi kwe-voltage engu-70%. Lokho kungitshela ukuthi iwashi lihlala lihamba.

Iningi lezivikeli zokukhuphuka kwegesi zihlala iminyaka emithathu kuya kwemihlanu ehhovisi elihlanzekile. Esitolo esishisayo esinokunyuka kwegesi nsuku zonke, lindela unyaka owodwa kuya kwemibili.Ngibhala usuku lokukhiqiza kuyunithi ngayinye esiyithengisayo.

Lokho Okushiwo Yizindinganiso

I-IEC 61643-11 ithi i-MOV kumele isasebenza ngemva kokunyuka kwe-amp eyodwa okungu-1,000. Lokho kuzwakala kukhulu, kodwa isiphepho esisodwa sasehlobo singaletha ama-hits angu-20. Yenza izibalo bese ubona ukuthi kungani ngicindezela abathengi ukuthi bashintshe ama-strips ekhalendeni, hhayi ngethemba.

Ithebula Ledatha Yangempela Elivela KuLabhorethri Yethu

Sisebenzise amasampula angu-200 ku-40 °C kanye no-230 V. Ithebula libonisa ukuthi i-voltage ye-clamp ikhuphuke nini ngo-10%:

Ukuphinda kabili ama-joule cishe kuphinda kabili impilo. Yingakho ngithengisa amabhodi e-high-joule ezimbonini zaseJalimane yize ebiza kakhulu ngo-18%.

Ingabe Usavikelekile?

Ngithumelele amakhasimende izinkinobho zokuhlola ezingu-500 ngeposi kwikota edlule. Bangu-23% kuphela abacindezele ngazo. Abanye bangama-flying blind, imishini yokubheja emugqeni okungenzeka ukuthi usuvele ufile ngamatshe.

Cindezela inkinobho yokuhlola kabili ngonyaka. Uma i-LED eluhlaza ihlala imnyama ngemva kokuhlolwa, ama-MOV asetshenziswa ngokuphelele futhi awusavikelekile.Ngifaka leli khadi kuwo wonke amabhokisi.

Umhlahlandlela Wokuzihlola Osheshayo

1. Susa yonke imithwalo exhunywe ku-inthanethi.
2. Cindezela bese ubamba inkinobho yokuhlola imizuzwana emi-3.
3. Khulula bese ubuka i-LED.
4. Uma kubuya kukhazimula, usenokuphila.
5. Uma ihlala ivaliwe noma ifiphala, phinda usebenzise umucu.

Isixazululo sami esingu-$0.25

Manje sesiphrinta ikhodi ye-QR esimweni ngasinye. Yiskena bese ubona inani eliqondile lama-joule asele, ngokusekelwe kukhodi yosuku kanye ne-algorithm elula. Akuyona ibanga lelebhu, kodwa kudlula ukuqagela.

Kufanele Ushintshe Nini Umvikeli Wokukhuphuka?

Ngishintsha yonke i-strip ehhovisi lami ngosuku lokuqala lokusebenza ngemva koNyaka Omusha WaseShayina. Ngiyiphatha njengokushintsha amabhethri okuthola intuthu—umshwalense oshibhile wokulahlekelwa okukhulu.

Shintsha isivikelo sokukhuphuka ngemva kokushaya kombani okukhulu, njalo eminyakeni emithathu, noma ngokushesha nje lapho ikesi lizizwa lifudumele noma i-LED isebenza ngendlela engavamile.Ngithumela isitoko esisha eMilan njalo ngekota ukuze abathengi bakwazi ukulandela lo mthetho.

Izindleko Zokulinda

Iklayenti elilodwa lase-UK lalinda iminyaka emihlanu. Ukwanda okukhulu kwabulala ama-PLC amathathu ngo-£4,800 lilinye. Ama-strips amasha abiza u-£12. Izibalo ziyalimaza.

Ikhalenda Elilula Lokufaka Esikhundleni

Sinamathisela lokhu ngaphakathi kwebhokisi lebhokisi:

Namathisela lokhu emnyango wephaneli yakho futhi awusoze waqagela futhi.

Isiphetho

Ngilahlekelwe yimali ngakho akudingeki ukuthi ukwenze lokho. Hlola kabili, shintsha njalo eminyakeni emithathu, bese uthenga ama-joules njengoba uthenga ikhofi—okuningi kungcono. Ngithinte ku-caroline@leikexing.com futhi ngizothumela amabhodi amasha avela eWenzhou ngaphambi kokuba kufike isiphepho esilandelayo.
