Kodi Zoteteza za Surge Zimayenda Moyipa?

Ndinatayapo chowongolera cha CNC cha $3,000 chifukwa chingwe "chatsopano" chinasiya kugwira ntchito mwakachetechete. Kupweteka kumeneko kunandiphunzitsa kukayikira LED iliyonse yowala.

Inde, zoteteza kugwedezeka Kutopa. Ma MOV awo amasweka, amayamwa mphamvu zochepa, ndipo pamapeto pake amasiya kukwera kwina molunjika mu zida zanu.Ndimayesa kuwonongeka kumeneku mu labu yanga ya Wenzhou sabata iliyonse.

Pitirizani kuwerenga ndipo ndidzakuwonetsani zizindikiro zenizeni, manambala, ndi malamulo osinthira omwe timagwiritsa ntchito tikatumiza makontena a 40-foot ku Berlin ndi Birmingham.

Bwanji Oteteza Othamanga Ntchito?

Ndikukumbukirabe nthawi yoyamba yomwe ndinawona MOV Kuwomba ngati chipolopolo chaching'ono mkati mwa chikwama cha pulasitiki choyera. Chithunzi chimenecho chinanditsimikizira kuti ziwalo izi ndi ngwazi zokhala ndi moyo waufupi.

A choteteza kugwedezeka Amathira ma volt owonjezera mu varistor zachitsulo-oxide. Varistors zimayamwa kugunda, koma kugunda kulikonse kumazidya mpaka zitasweka ndikusiya kuyendetsa.Ndimayesa izi mu fakitale yathu ya 2,000 m².

Kodi Mkati mwa Mzerewu Muli Chiyani?

Ogula ambiri amangoona switch yowala ndi nyali yobiriwira. Ndimatsegula chikwamacho ndikuwawonetsa magawo atatu:

Kodi mungagwiritse ntchito ndalama zingati?

Ma Joules ali ngati ndalama zomwe zili m'chikwama. Chida cha J 1,000 chingatenge kugunda kwa J kamodzi kapena kugunda kwa J 100. Ndalemba ma surges mu fakitale ya Hamburg kwa miyezi isanu ndi umodzi. Gome ili pansipa likuwonetsa zomwe zidakhudza mzere wawo:

Pofika mu Marichi, wotetezayo anali atatsala ndi 445 J yokha. Pa liwiro limenelo, ikanakhala yopanda kanthu chilimwe chisanafike.

Chifukwa Chake Kuwala Kobiriwira Kuli Mabodza

LED imangokuuzani kuti fuse ili ndi moyo. MOV ikhoza kugawidwa pakati ndipo kuwalako kumawalabe. Ndikupempha ogula kuti ayesere ndi choyesera chosavuta chotulutsira magetsi komanso banki yonyamula katundu kamodzi pachaka. Ngati kutsika kwa magetsi kukwera pamwamba pa 5%, MOV imachoka.

Zizindikiro Zosonyeza Kuti Mtetezi Wanu Wokwera Angalephereke

Chaka chatha kasitomala wina wa ku France adabweza gulu lomwe limawoneka bwino kunja. Mkati mwake, njira zofiirira zoyaka moto zinkayenda ngati misewu yaying'ono. Fungo la pulasitiki yokazinga ndi chenjezo lomwe sindimalinyalanyaza.

Choteteza chanu cha mafunde chikulephera kugwira ntchito ngati chikwamacho chili chofunda, LED ikuzima, kapena mukumva phokoso lochepa. Ndimasintha mzere uliwonse womwe ukuwonetsa zizindikiro izi.Ndimaona 100% ya makatoni athu otuluka kuti ndione zizindikiro izi.

Imvani Chipolopolo

Pambuyo pa ola limodzi lodzaza, kutentha kwa pamwamba kuyenera kukhala pansi pa 40 °C. Ndimagwiritsa ntchito mfuti ya IR ya $20 ndipo ndimasanthula chotulutsira chilichonse. Malo otentha amatanthauza kuti MOV ikutulutsa mphamvu ndikusintha mphamvu kukhala kutentha.

Mayeso a Kununkhiza

Bolodi labwino limanunkhiza ngati pulasitiki ndi chitsulo. MOV yomwe yatsala pang'ono kutha imatulutsa fungo labwino komanso lokoma. Ndikuphunzitsa gulu lathu la QC kuti lizindikire izi pasanathe masekondi asanu pamzere.

Mapepala achinyengo a LED

Tinapanga tebulo laling'ono lomwe tinaliika mkati mwa bokosi lililonse lotumizira katundu:

Kodi Oteteza Odwala Amakhala Nthawi Yaitali Bwanji?

Ndimasunga zitsanzo zomwe zikuyenda maola 24 pa sabata pa voltage ya 1.5×. Patatha miyezi 36, theka la MOVs linatsika pansi pa voltage ya clamp ya 70%. Zimenezi zimandisonyeza kuti nthawi zonse nthawi zonse imakhala ikuyenda.

Zoteteza zambiri za surge zimatha zaka zitatu mpaka zisanu muofesi yoyera. Mu shopu yotentha yokhala ndi kukwera kwa tsiku ndi tsiku, yembekezerani chaka chimodzi mpaka ziwiri.Ndimasindikiza tsiku lopanga pa chipangizo chilichonse chomwe timagulitsa.

Zimene Miyezo Ikunena

IEC 61643-11 imati MOV iyenera kugwirabe ntchito ikatha kukwera kwa ma amp imodzi 1,000. Zikumveka ngati zazikulu, koma mphepo yamkuntho imodzi yachilimwe ikhoza kubweretsa ma hits 20. Yesani kuwerengera ndipo mukuwona chifukwa chake ndikukakamiza ogula kuti asinthe ma strips pa kalendala, osati ndi chiyembekezo.

Tebulo la Deta Yeniyeni kuchokera ku Lab Yathu

Tinayesa zitsanzo 200 pa 40 °C ndi 230 V. Gome likuwonetsa pamene mphamvu ya clamp inakwera ndi 10%:

Kuwirikiza kawiri ma joules kumawonjezera nthawi ya moyo wa ma joules. Ichi ndichifukwa chake ndimagulitsa ma board apamwamba kwambiri ku mafakitale aku Germany ngakhale kuti amawononga ndalama zokwana 18%.

Kodi Mukutetezedwabe?

Ndinatumiza mabatani 500 oyesera kwa makasitomala kotala lapitali. 23% yokha ndi omwe adawasindikiza. Ena onse ndi makina obetcha omwe ali pa mzere womwe mwina wafa kale.

Dinani batani loyesera kawiri pachaka. Ngati LED yobiriwira ikhalabe yakuda pambuyo pa mayeso, ma MOV atha ntchito ndipo simulinso otetezeka.Ndimawonjezera khadi ili ku katoni iliyonse.

Buku Lodzifufuza Mwachangu

1. Chotsani katundu yense.
2. Dinani ndikusunga swichi yoyesera kwa masekondi atatu.
3. Tulutsani ndikuyang'ana LED.
4. Ngati ibwerera bwino, udzakhalabe ndi moyo.
5. Ngati sichikugwira ntchito kapena chachepa, bwerezaninso mzerewo.

Yankho langa la $0.25

Tsopano tikusindikiza QR code pa chilichonse. Mukachijambula, muwona kuchuluka kwa ma joule komwe kwatsala, kutengera tsiku ndi algorithm yosavuta. Siyofanana ndi labu, koma ndi yopambana kuganiza.

Kodi Muyenera Kusintha Liti Mtetezi Wopitirira?

Ndimasintha chilichonse muofesi yanga tsiku loyamba la ntchito pambuyo pa Chaka Chatsopano cha ku China. Ndimachiona ngati kusintha mabatire owunikira utsi—inshuwaransi yotsika mtengo yolimbana ndi kutayika kwakukulu.

Sinthani choteteza cha surge pambuyo pa kugunda kwa mphezi kwakukulu, zaka zitatu zilizonse, kapena chivundikirocho chikangoyamba kutentha kapena LED ikakhala yosiyana.Ndimatumiza katundu watsopano ku Milan kotala lililonse kuti ogula athe kutsatira lamuloli.

Mtengo Wodikira

Kasitomala m'modzi ku UK anadikira zaka zisanu. Kukwera kwa mtengo kunapha ma PLC atatu pamtengo wa £4,800 iliyonse. Zingwe zatsopanozi zinagulidwa pa £12. Masamuwo ndi owopsa.

Kalendala Yosavuta Yosinthira

Timayika izi mkati mwa chivundikiro cha katoni:

Ikani izi pachitseko cha panelo yanu ndipo simudzaganizanso.

Mapeto

Ndataya ndalama kotero simuyenera kutero. Yesani kawiri, sinthanani zaka zitatu zilizonse, ndipo gulani ma joules ngati momwe mumagulira khofi—zambiri ndi zabwino. Nditumizireni imelo ku caroline@leikexing.com ndipo ndidzatumiza ma board atsopano kuchokera ku Wenzhou mphepo yamkuntho isanayambe.
