Ngaba i Umkhuseli wokunyuka kwi Ibhokisi yoMbane Ingaba Ibangela Iingxaki Okanye Inika Ukhuseleko?

Ndakha ndabukela umthengi elahlekelwa yi-30 K USD ngexesha elinye. Elo vumba leemoto ezitshisiweyo lisandivusa ebusuku.

Isithinteli sokushushuluza esifakwe kwipaneli asibangeli ngxaki ukuba ukhetha i-voltage efanelekileyo uze uvumele ingcali enelayisenisi ukuba iyifake. Iyayinqumla i-spike ngaphambi kokuba ishiye isiseko semitha, ukuze oomatshini bakho bahlale bekhuselekile.

Apha ngezantsi ndikubonisa onke amathandabuzo abathengi abafana noJeff abandithumelele wona kunyaka ophelileyo. Qhubeka ufunda kwaye uya kwazi ukuba kutheni songeza ezi bhokisi zincinci kuzo zonke iikhabhathi eziphuma kwisityalo sethu saseWenzhou.

Yintoni i-Surge Protector kwi-Electric Box?

Ndisakhumbula ixesha lokuqala ndibambe enye. Yayibonakala ngathi yi-fat circuit breaker, kodwa ileyibhile yayibhalwe “SPD 40 kA”. Ndabuza umphathi wam, “Ingaba le nto yinto nje yokutshintsha?”

Isithinteli sokushushu kwebhokisi yombane sisixhobo sesinyithi esiqhagamshela ngqo kwibhasi ephambili. Sifunxa okanye siguqule i-voltage eyongezelelweyo ngaphantsi kwe-nanoseconds ezingama-25, ngoko ke amandla ongezelelweyo akaze afikelele kwii-breakers zakho.

Indlela Eyahluke Ngayo Kwi-Power Strip

Abathengi abaninzi bayayixuba le migca mibini. I-power strip ihleli ecaleni kwedesika yakho kwaye ikunika iindawo zokuphuma ezingaphezulu. I-SPD yephaneli ihleli ngaphakathi kwikhabhinethi yesinyithi kwaye ikhusela yonke indawo. I-strip isenokuma kwi-1 kA. Iyunithi yethu yebhokisi iqala kwi-20 kA kwaye inyuke iye kwi-200 kA. Elo thuba likhulu xa kufika isaqhwithi.

Ngaphakathi kweBhokisi

Vula enye uze ubone iibhloko ezintathu zesinyithi. Ibhloko enye yi-varistor. Itya i-spike. Ibhloko yesibini yityhubhu yegesi. Iyadubula xa i-spike inkulu kakhulu. Ibhloko yesithathu yi-fuse. Iyafa ukuze ezinye ziphile. Zonke ezintathu zihlala kwi-DIN rail kwaye zithatha izithuba ezintathu kuphela. Loo ndawo incinci igcina isityalo esipheleleyo.

Amanani Okwenyani Avela KwiLebhu Yethu

Sibethe i-spike ye-6 kV kwibhodi yovavanyo. I-voltage kwicala lomthwalo yayiyi-420 V kuphela xa i-SPD yayivuliwe. Ngaphandle kwayo, umthwalo ofanayo wabona i-2 850 V. Uninzi lwee-drives lungaphumeleli kwi-1 800 V. Itheyibhile ibonisa umsantsa.

Isebenza njani i-Surge Protector?

Bendisoloko ndicinga ukuba ngumlingo. Emva koko injineli yethu yandibonisa igrafu enye elula. Umgca obomvu sisipikili. Umgca oluhlaza okwesibhakabhaka sisibambo. Apho zidibana khona, isipikili siyafa.

Isixhobo sijonga i-sine wave. Xa i-voltage itsiba ngaphezulu kwe-1 100 V, inciphisa umgca ukuya emhlabeni imizuzwana embalwa. Amandla angaphezulu ajika abe bubushushu ngaphakathi kwi-varistor. I-wave yehla iye kwi-230 V kwaye i-PLC yakho ayiboni ukutsiba.

Amanqanaba Amathathu Esiwasebenzisayo eWenzhou

Sakha amanqanaba amathathu. Inqanaba lokuqala lihlala kwimitha. Inqanaba lesibini lihlala kwiphaneli engaphantsi. Inqanaba lesithathu lihleli ecaleni kwendlela yokuqhuba. Inqanaba ngalinye litya inxalenye ye-spike. Ngale ndlela akukho nxalenye ithile ifumana impumelelo epheleleyo. Abathengi abanjengoJeff bonga imali kuba batshintsha inqanaba lokuqala kuphela emva kwesaqhwithi esikhulu.

Kutheni iSpeed ​​​​Beats Size

I-varistor enkulu ibukeka inamandla, kodwa isantya siyaphumelela. Itshiphu yethu entsha ye-25 ns idlula ibhloko endala ye-100 ns izihlandlo ezi-4. Isithuba sivakala sincinci, kodwa i-drive ingatshixa kwi-50 ns. Isantya sikhuselekile.

Ngaba ii-Surge Protectors zibangela iingxaki?

NgoMatshi ophelileyo umthengi undithumelele i-imeyile, “Jason, i-SPD yakho itshise ibha yam yebhasi.” Ndaya kwindawo yebhasi ndaza ndafumana umntu ofake i-akhawunti esebenzisa iyunithi ye-120 V kumgca we-277 V. Iyunithi yafa yaza yathatha ibha nayo.

Isithinteli sokushushuluza asizukubangela iimpazamo ukuba ulinganisa i-voltage, i-short-circuit current, kunye nobukhulu bentambo. Iingxaki zentsimi ezingama-90% zivela ekufakweni okungalunganga, hayi inxalenye.

Iimpazamo Ezintathu Eziphambili Esizibonayo

1. I-voltage engalunganga. Inxalenye ye-120 V kumgca we-240 V iya kuvela emva kweentsuku.
2. Ucingo olukhululekileyo. Ucingo oluyi-2.5 mm² kwindlela ye-100 kA lujika lube bomvu lushushu.
3. Akukho fuse. Xa inxalenye ifa, ibhasi ihlala iphila kwaye iyanyibilika.

Indlela Esizimisa Ngayo Iimpazamo

Sifaka ilebheli enkulu kwicala ngalinye. Ilebheli ibonisa ii-volts eziphezulu kunye ne-torque kwi-N·m. Sikwathumela nesiphathi sefuse yesinyithi kwibhokisi enye. Umthengi akanakuyitsiba.

Itafile yokujonga ngokukhawuleza kaJeff

Iingenelo zoKhuselo loKhuphuko kwiBhokisi leBreak

Ndihambe ngenyawo kwifektri yaseJamani kunyaka ophelileyo. Babeneemoto zokuqhuba ezingama-300 kumgangatho omnye. Umphathi wandixelela, “Jason, uqhankqalazo olunye lubulale iimoto zokuqhuba ezilishumi. Ukusukela oko songeze i-SPD yakho, asilahlekelwanga nanye.”

Ukufaka isikhuseli kwibhokisi ye-breaker kunciphisa ixesha lokungasebenzi, konga amabhodi, kwaye kunciphisa iindleko zizonke zobunini. Inxalenye enye ye-40 USD inokonga i-3 000 USD kwiidrives kunye neentsuku zexesha lokungasebenzi elilahlekileyo.

Apho Imali Iya Khona

Inqwelo entsha ibiza i-1 200 USD. Ingcali yezobuchwepheshe ibiza i-80 USD ngeyure. Usuku olulahlekileyo lubiza i-5 000 USD kwimihla yokuthunyelwa engaphumelelanga. Itheyibhile igcina imali.

Ukuphumelela Okufihliweyo

Iinkampani zeinshorensi eFransi ngoku zinika isaphulelo se-5% ukuba ubonisa isiqinisekiso se-SPD. Loo 5% idlula ixabiso lenxalenye kunyaka wokuqala.

Ungayikhetha njani i-Surge Protector efanelekileyo kwiBhokisi yakho yoMbane?

UJeff wabhala wathi, “Ndifuna ii-pcs ezingama-2 000, kodwa andiyazi inombolo yenxalenye.” Ndamthumelela iphepha elinye. Waphendula ngomgca omnye wathi, “Ndigqibile.”

Khetha i-voltage, umbane ophezulu, kunye ne-form factor. Emva koko jonga uhlobo lomsila. Iyunithi yerail ye-40 kA 230 V DIN enomsila we-6 mm² ilingana ne-80% yemisebenzi.

Iphepha Elihamba Ngenyathelo Ngenyathelo

1. Funda ii-volts zomgca. 230 V okanye 120 V okanye 277 V?
2. Funda ii-amp ze-short-circuit kwi-main breaker. 10 kA okanye 50 kA?
3. Bala izigaba. Inye, yahlulwe, okanye ezintathu?
4. Khetha ifomu. I-DIN rail okanye i-foot mount?
5. Khetha umsila. Ucingo oluyi-6 mm² okanye i-25 mm² lug?

Imephu yeKhowudi eKhawulezayo

Izicelo ze-Surge Protectors

Ndisandula ukuthumela ii-pcs eziyi-1 200 e-UK. Ziza kuhlala kwiirakhi zedatha, iifama, kunye nophahla lwevenkile enkulu. Inxalenye efanayo, uhlobo olufanayo.

Ungasebenzisa i-SPD enye ekhayeni, kwisityalo, okanye kwifama yomoya. Ukuba nje uhambelana nee-volts kunye nee-amps, le nxalenye itya i-spike naphi na.

Umthetho Omnye Kubo Bonke

Gcina intambo imfutshane. Ngaphantsi kwe-50 cm ukusuka kwi-breaker ukuya kwi-SPD. I-cm nganye eyongezelelweyo yongeza i-10 nH ye-inductance kwaye iphakamisa ii-volts ezivumelayo. Intambo emfutshane, umthwalo okhuselekileyo.

Isiphelo

I-SPD yephaneli yi-inshurensi engabizi kakhulu. Yilinganise kakuhle, yifake mfutshane, uze ulale ngelixa isivuthuvuthu sifika. Ndithumelele i-imeyile ku-caroline@leikexing.com ukuze ufumane iphepha leenkcukacha zasimahla kunye nesicatshulwa seeyure ezingama-24.
