Ngaba ii-Surge Protectors zihamba kakubi?
Ndakha ndalahlekelwa yi-CNC controller ye-$3,000 ngenxa yokuba umcu "omtsha" wawuyeka ukusebenza. Loo ntlungu yandifundisa ukuba ndizibuze yonke i-LED ekhanyayo.
Ewe, izikhuseli zokuxhathisa iyaphela. Ii-MOV zazo ziyaqhekeka, zifunxa amandla amancinci, kwaye ekugqibeleni zivumela enye inyuke iye ngqo kwizixhobo zakho.Ndilinganisa oku kubola kwilebhu yam yaseWenzhou qho ngeveki.
Qhubeka ufunda kwaye ndiza kukubonisa iimpawu ezichanekileyo, amanani, kunye nemithetho yokutshintsha esiyisebenzisayo xa sithumela izikhongozeli ezingama-40-foot eBerlin naseBirmingham.
Njani Abakhuseli bokunyuka Umsebenzi?
Ndisakhumbula ixesha lokuqala endabona ngalo I-MOV ukuvuthela njenge-firecracker encinci ngaphakathi kwebhokisi yeplastiki emhlophe. Loo mfanekiso wandiqinisekisa ukuba la malungu ngamaqhawe aphila ubomi obufutshane.
A umkhuseli wokuxhathisa Ilahla ii-volts ezongezelelweyo kwii-varistor ze-metal-oxide. Ii-varistor ziyayifunxa loo nto ibethayo, kodwa yonke into ebethayo iyayitya ide iqhekeke ize iyeke ukuqhuba.Ndiyivavanya le nto kumzi-mveliso wethu ongama-2,000 m².
Yintoni Engaphakathi Kwi-Strip?
Uninzi lwabathengi lubona kuphela iswitshi ekhazimlayo kunye nesibane esiluhlaza. Ndivula ityesi ndize ndibabonise iindawo ezintathu:
| Inxalenye | Umsebenzi | I-WeakPoint |
| I-MOV | Iikliphu ze-volts eziphezulu | Iintanda emva kwe ~300 J |
| Ityhubhu yegesi | Uphatha iilayini zefowuni | Inxiba kancinci kune-MOV |
| Ifusi | Ukusika kufutshane kakhulu | Ukusetyenziswa kube kanye |
Zingaphi iiJoules onokuzisebenzisa?
IiJoules zifana nemali ekwisipaji. Iyunithi ye-J eyi-1,000 ingathatha i-J hit enye okanye i-J hit ezilishumi. Ndibhale ii-surges kwisityalo saseHamburg kangangeenyanga ezintandathu. Itheyibhile engezantsi ibonisa ukuba yintoni echaphazele imigca yazo:
| Inyanga | Amandla okunyuka (J) | Inani leeHits |
| uJanuwari | 120 | 14 |
| uFebruwari | 85 | 9 |
| uMatshi | 350 | 3 |
| Isimbuku | 555 | 26 |
NgoMatshi, isikhuseli sasisele ne-445 J kuphela. Ngeli xesha yayiza kuba ingenanto ngaphambi kwehlobo.
Kutheni Ukukhanya Okuluhlaza Kulele
I-LED ikuxelela kuphela ukuba i-fuse iyaphila. I-MOV inokwahlulwa phakathi kwaye ukukhanya kusakhanya. Ndicela abathengi ukuba bavavanye nge-outlet tester elula kunye ne-load bank kanye ngonyaka. Ukuba i-voltage drop inyuka ngaphezulu kwe-5%, i-MOV ayisekho.
Iimpawu zokuba uMkhuseli wakho woKhuphuko usenokungaphumeleli
Kunyaka ophelileyo umthengi waseFransi wathumela inqwaba eyayibonakala igqibelele ngaphandle. Ngaphakathi, imizila emdaka etshileyo yayihamba njengeendlela ezincinci. Elo vumba leplastiki eyosiweyo lisilumkiso endingasoze ndisityeshele.
Isithinteli sakho sokuhamba siyasilela ukuba ikheyisi ishushu, i-LED iyadanyaza, okanye uva isandi esincinci. Nditshintsha nayiphi na ilaphu ebonisa ezi mpawu.Ndijonga iibhokisi zethu eziphumayo nge-100% ukuze ndibone ezi zikhokelo.
Yiva iqokobhe
Emva kweyure enye yokulayisha, ubushushu bomphezulu kufuneka buhlale bungaphantsi kwama-40°C. Ndisebenzisa isibhamu se-IR se-$20 kwaye ndiskena iplagi nganye. Indawo eshushu ithetha ukuba i-MOV ivuza umbane kwaye iguqula amandla abe bubushushu.
Uvavanyo lwe-Sniff
Ibhodi ephilileyo inuka njengeplastiki nesinyithi. I-MOV efayo ikhupha ivumba elimnandi nelibukhali. Ndiqeqesha iqela lethu le-QC ukuba liqaphele oku ngaphantsi kwemizuzwana emihlanu emgceni.
Iphepha lokukhohlisa le-LED
Sakha itafile encinci esiyinamathisela ngaphakathi kwibhokisi nganye yokuthumela ngaphandle:
| I-LEDState | Intsingiselo | Isenzo |
| Uluhlaza oluqinileyo | Zonke zilungile | Qhubeka usebenzisa |
| Icinyiwe | Ifusi ivuthelwe | Tshintsha ngoku |
| Ukufiphala okanye ukudanyaza | I-MOV iyafa | Tshintsha kungekudala |
Zihlala ixesha elingakanani ii-Surge Protectors?
Ndigcina irakhi yeesampulu ezisebenza iiyure ezingama-24 ngosuku, iintsuku ezisixhenxe nge-voltage eyi-1.5×. Emva kweenyanga ezingama-36, isiqingatha seeMOV sehle ngaphantsi kwe-70% ye-clamp voltage. Oko kundixelela ukuba iwotshi ihlala itshintsha.
Uninzi lwezixhobo zokukhusela ukuvuza kwamanzi zihlala iminyaka emithathu ukuya kwemihlanu kwiofisi ecocekileyo. Kwivenkile eshushu enezivuthuvuthu zemihla ngemihla, lindela unyaka omnye ukuya kwemibini.Ndibhala umhla wokuveliswa kweyunithi nganye esiyithengisayo.
Oko Kuthethwa YiMigangatho
I-IEC 61643-11 ithi i-MOV kufuneka isasebenza emva kokunyuka kwe-1,000 ye-amp enye. Oko kuvakala kukhulu, kodwa isivuthuvuthu esinye sasehlotyeni sinokuzisa ii-hits ezingama-20. Yenza izibalo uze ubone ukuba kutheni ndinyanzela abathengi ukuba batshintshe ii-strip kwikhalenda, kungekhona ngethemba.
Itheyibhile yeDatha yokwenyani evela kwiLebhu yethu
Sisebenzise iisampulu ezingama-200 kwi-40 °C kunye ne-230 V. Itheyibhile ibonisa xa i-voltage ye-clamp inyuke nge-10%:
| Uvavanyo lweJoule | Ubomi obuPhakathi (iinyanga) | I-5% ayiphumelelanga (ngeenyanga) |
| 600 J | 28 | 18 |
| 900 J | 42 | 30 |
| 1,500 J | 60 | 48 |
Ukuphinda kabini ii-joule kuphinda kabini ubomi. Yiyo loo nto ndithengisa iibhodi ze-high-joule kwiifektri zaseJamani nangona zibiza ngaphezulu nge-18%.
Ngaba Usakhuselekile?
Ndithumele amaqhosha ovavanyo angama-500 kubathengi kwikota ephelileyo. Ngama-23% kuphela awacinezele. Amanye asebenza ngokubhabha, oomatshini bokubheja kwi-strip esenokuba sele ifile ngamatye.
Cinezela iqhosha lovavanyo kabini ngonyaka. Ukuba i-LED eluhlaza ihlala imnyama emva kovavanyo, ii-MOV zigqityiwe kwaye awusakhuselekanga.Ndifaka eli khadi kwibhokisi nganye.
Isikhokelo Sokuzihlola Esikhawulezileyo
- Susa yonke imithwalo eplagiweyo.
- Cinezela uze ubambe iswitshi yovavanyo imizuzwana emi-3.
- Khulula ubukele i-LED.
- Ukuba ibuya iqaqambile, usenobomi.
- Ukuba ayisebenzi okanye iyacima, phinda usebenzise umcu.
Isisombululo sam se-$0.25
Ngoku siprinta ikhowudi yeQR kwimeko nganye. Yiskena uze ubone inani elichanekileyo leejoule ezishiyekileyo, ngokusekelwe kwikhowudi yomhla kunye ne-algorithm elula. Ayilodidi lwelebhu, kodwa iyodlula ukuqikelela.
Ufanele Utshintshe Nini uMkhuseli Wokukhuphuka?
Nditshintsha yonke into eofisini yam ngosuku lokuqala lokusebenza emva koNyaka oMtsha waseTshayina. Ndiyithatha njengokutshintsha iibhetri zesixhobo sokufumana umsi—inshorensi engabizi kakhulu xa ndilahlekelwa kakhulu.
Tshintsha isikhuseli sokushushuba emva kokuba umbane ubethe ngamandla, rhoqo emva kweminyaka emithathu, okanye ngokukhawuleza xa ikesi ivakala ishushu okanye i-LED isenza ngendlela engaqhelekanga.Ndithumela izitokhwe ezintsha eMilan rhoqo ngekota ukuze abathengi bakwazi ukulandela lo mthetho.
Iindleko zokulinda
Umthengi omnye wase-UK walinda iminyaka emihlanu. Ukunyuka okukhulu kwabulala ii-PLC ezintathu nge-£4,800 nganye. Ii-strips ezintsha zibiza i-£12. Izibalo ziyabuhlungu.
Ikhalenda elula yokutshintsha
Sincamathisela oku ngaphakathi kweflephu yekhathoni:
| Usetyenziso lweYearin | Isenzo |
| 0–1 | Uvavanyo kuphela |
| 2 | Vavanya kabini |
| 3 | Ukutshintshwa kwee-odolo |
| 4+ | Tshintsha ngoku, akukho mfuneko yovavanyo |
Namathisela oku kucango lwephaneli yakho kwaye awusayi kuphinda uqagele.
Isiphelo
Ndilahlekelwe yimali ngoko ke akufuneki ukuba wenze njalo. Vavanya kabini, tshintshana rhoqo emva kweminyaka emithathu, kwaye uthenge ii-joules njengoko uthenga ikofu—ezinye zingcono. Ndithumelele umnxeba ku-caroline@leikexing.com kwaye ndiza kuthumela iibhodi ezintsha ezivela eWenzhou ngaphambi kokuba kufike isivuthuvuthu esilandelayo.
