Ingabe Isivikelo Sokukhuphuka Ebhokisini Likagesi Sibangela Izinkinga Noma Sihlinzeka Ngokuvikelwa?
Ingabe i- Isivikelo Sokukhuphuka use Ibhokisi Likagesi Kubangela Izinkinga Noma Kunikeza Isivikelo?
Ngake ngabuka iklayenti lilahlekelwa yi-30 K USD ngesikhathi esisodwa. Lelo phunga lama-drive ashisiwe lisangivusa ebusuku.
Isivikelo sokukhuphuka esifakwe ephanelini asibangeli inkinga uma ukhetha i-voltage efanele bese uvumela uchwepheshe onelayisensi ukuthi ayifake. Sinqamula i-spike ngaphambi kokuba isuke esisekelweni semitha, ukuze imishini yakho ihlale iphephile.
Ngezansi ngizokukhombisa konke ukungabaza abathengi abanjengoJeff abangithumelele khona ngeposi ngonyaka odlule. Qhubeka ufunda futhi uzokwazi ukuthi kungani sifaka la mabhokisi amancane kumakhabhinethi ngalinye eliphuma esitshalweni sethu saseWenzhou.
Iyini i-Surge Protector ebhokisini likagesi?
Ngisakhumbula ngesikhathi ngiyiphethe okokuqala. Yayibukeka njenge-circuit breaker ekhuluphele, kodwa ilebula yayibhalwe ukuthi “SPD 40 kA”. Ngabuza umphathi wami, “Ingabe le nto imane iyiswishi nje?”
Isivikelo sokukhuphuka kwebhokisi likagesi yidivayisi yensimbi exhuma ngqo ebhasini eliyinhloko. Imunca noma iguqule i-voltage eyengeziwe ngaphansi kwamasekhondi angu-25, ngakho-ke amandla engeziwe awafiki kuma-breaker akho.
Indlela Ehluke Ngayo Ku-Power Strip
Abathengi abaningi bayaxuba lokhu kokubili. I-power strip ihlezi eduze kwedeski lakho futhi ikunikeza izindawo zokuphuma ezengeziwe. Iphaneli ye-SPD ihlezi ngaphakathi kwekhabhinethi yensimbi futhi iqapha yonke indawo. I-strip ingase ime ku-1 kA. Iyunithi yethu yebhokisi iqala ku-20 kA futhi ikhuphukela ku-200 kA. Leso sikhala sikhulu lapho kufika isiphepho.
Ngaphakathi Kwebhokisi
Vula eyodwa bese ubona amabhlogo amathathu ensimbi. Ibhloko elilodwa liyi-varistor. Lidla i-spike. Ibhloko lesibili liyipayipi legesi. Liyadubula uma i-spike inkulu kakhulu. Ibhloko lesithathu liyi-fuse. Liyafa ukuze abanye baphile. Bonke abathathu bahlala e-DIN rail futhi bathatha izikhala ezintathu kuphela. Leso sikhala esincane sisindisa isitshalo esigcwele.
Izinombolo Zangempela Ezivela KuLebhu Yethu
Sishaye i-spike engu-6 kV ebhodini lokuhlola. I-voltage ohlangothini lomthwalo yayingu-420 V kuphela ngesikhathi i-SPD isebenza. Ngaphandle kwayo, umthwalo ofanayo wabona ama-2 850 V. Ama-drive amaningi ahluleka ku-1 800 V. Ithebula libonisa igebe.
| Indawo Yokuhlola | Nge-SPD (V) | Ngaphandle kwe-SPD (V) |
| I-LN ilayishwa | 420 | 2850 |
| I-L-PE ilayishwa | 480 | 3100 |
| I-N-PE ilayishwa | 230 | 1950 |
Usebenza Kanjani Umvikeli Wokukhuphuka?
Bengicabanga ukuthi kuwumlingo. Unjiniyela wethu wabe esengibonisa igrafu eyodwa elula. Umugqa obomvu uyi-spike. Umugqa oluhlaza okwesibhakabhaka uyi-clamp. Lapho zihlangana khona, i-spike iyafa.
Idivayisi ibuka igagasi le-sine. Uma i-voltage igxuma ngaphezu kwe-1 100 V, ifinyeza umugqa uye phansi imizuzwana embalwa emincane. Amandla engeziwe aphenduka ukushisa ngaphakathi kwe-varistor. Igagasi lehla liye ku-230 V futhi i-PLC yakho ayikaze ikubone ukugxuma.
Izigaba Ezintathu Esizisebenzisayo eWenzhou
Sakha amagreyidi amathathu. Isigaba sokuqala sihlala kumitha. Isigaba sesibili sihlala kuphaneli encane. Isigaba sesithathu sihlala eduze kwedrayivu. Isigaba ngasinye sidla ingxenye ye-spike. Ngale ndlela akukho ngxenye eyodwa ethola ukushaywa okuphelele. Abathengi abanjengoJeff bonga imali ngoba bathatha indawo yesigaba sokuqala kuphela ngemva kwesiphepho esikhulu.
| Isiteji | Indawo | Ubuningi Bamanje | Izindleko (i-USD) |
| Okukodwa | Iphaneli eyinhloko | 200 kA | 42 |
| Okubili | Iphaneli engaphansi | 80 kA | 28 |
| Okuthathu | Uhlangothi lokushayela | 20 kA | 15 |
Kungani Isivinini Sishaya Usayizi
I-varistor enkulu ibukeka inamandla, kodwa isivinini siyanqoba. I-chip yethu entsha engu-25 ns idlula ibhulokhi endala engu-100 ns izikhathi ezine. Igebe lizwakala lincane, kodwa idrayivu ingavala ama-50 ns. Isivinini siphephile.
Ingabe Abavikeli Bokukhuphuka Babangela Izinkinga?
NgoMashi odlule umthengi wangithumelela i-imeyili ethi, “Jason, i-SPD yakho ishise ibha yami yebhasi.” Ngandiza ngaya endaweni ngathola ukuthi umfakisi usebenzise iyunithi engu-120 V entanjeni engu-277 V. Iyunithi yafa yathatha ibha nayo.
Isivikelo sokukhuphuka ngeke sibangele amaphutha uma ulinganisa i-voltage, i-short-circuit current, kanye nosayizi wentambo. Izinkinga zensimu ezingama-90% zivela ekufakweni okungalungile, hhayi engxenyeni.
Amaphutha Amathathu Aphezulu Esiwabonayo
- I-voltage engalungile. Ingxenye engu-120 V emugqeni ongu-240 V izovela ezinsukwini ezimbalwa.
- Ucingo oluxegayo. Ucingo oluyi-2.5 mm² endleleni engu-100 kA luphenduka lube bomvu lushise.
- Akukho fuse. Lapho ingxenye ifa, ibhasi lihlala liphila futhi liyancibilika.
Indlela Esimisa Ngayo Amaphutha
Sifaka ilebula elikhulu ohlangothini ngalunye. Ilebula libonisa ama-volts aphezulu kanye ne-torque ku-N·m. Siphinde sithumele isibambi se-fuse sensimbi ebhokisini elifanayo. Umthengi akakwazi ukusidlula.
Ithebula Lokuhlola Ngokushesha LikaJeff
| Indawo Yokuhlola | Inani Elilungile | Inani Lokwehluleka |
| Usayizi wentambo | ≥ 6 mm² | 2.5 mm² |
| I-Torque | 2.2 N·m | qinisa isandla |
| I-Fuse | 63 A gG | akukho fuse |
Izinzuzo Zokuvikelwa Kokukhuphuka Ebhokisini Lokuqhekeka
Ngahamba ngenyawo efemini yaseJalimane ngonyaka odlule. Babenezimoto zokushayela ezingu-300 esitezi esisodwa. Umphathi wangitshela ukuthi, “Jason, isiteleka esisodwa sasibulala izimoto zokushayela eziyishumi. Selokhu senezele i-SPD yakho, asilahlekelwa yilutho.”
Ukufaka isivikelo ebhokisini lokuvula idrayivu kunciphisa isikhathi sokungasebenzi, konga amabhodi, futhi kunciphisa izindleko eziphelele zobunikazi. Ingxenye eyodwa engu-40 USD ingonga u-3 000 USD kuma-drive kanye nezinsuku zesikhathi sokusebenza esilahlekile.
Lapho Imali Iya Khona
Idrayivu entsha ibiza u-1 200 USD. Uchwepheshe ubiza u-80 USD ngehora. Usuku olulahlekile lubiza u-5 000 USD ezinsukwini zokuthunyelwa ezingakafiki. Ithebula lifaka imali.
| Into | Izindleko (i-USD) |
| I-SPD | 40 |
| Idrayivu entsha | 1200 |
| Isikhathi sobuchwepheshe (amahora ama-4) | 320 |
| Usuku olulahlekile | 5000 |
| I-Net save | 6480 |
Ukunqoba Okufihliwe
Izinkampani zomshuwalense eFrance manje zinikeza isaphulelo esingu-5% uma ubonisa isitifiketi se-SPD. Lokho okungu-5% kudlula izindleko zezingxenye zonyaka wokuqala.
Ungayikhetha Kanjani I-Surge Protector Efanele Yebhokisi Lakho Likagesi?
UJeff wabhala, “Ngidinga ama-pcs angu-2 000, kodwa angiyazi inombolo yengxenye.” Ngamthumelela ishidi elilodwa. Waphendula ngomugqa owodwa, “Kuqediwe.”
Khetha i-voltage, amandla kagesi aphezulu, kanye ne-form factor. Bese uhlola uhlobo lomsila. Iyunithi yesitimela engu-40 kA 230 V DIN enomsila ongu-6 mm² ifanelana nama-80% emisebenzi.
Ishidi Lesinyathelo Ngesinyathelo
- Funda ama-volts omugqa. 230 V noma 120 V noma 277 V?
- Funda ama-amp we-short-circuit ku-main breaker. 10 kA noma 50 kA?
- Bala izigaba. Eyodwa, ehlukene, noma ezintathu?
- Khetha ifomu. Isitimela se-DIN noma i-foot mount?
- Khetha umsila. Ucingo oluyi-6 mm² noma i-lug engu-25 mm²?
Imephu Yekhodi Esheshayo
| Ikhodi | Ama-volts | Izigaba | kA | Umsila |
| I-LK-40-1P | 230 | 1 | 40 | 6 mm² |
| I-LK-80-3P | 400 | 3 | 80 | 25 mm² |
| I-LK-200-3P | 400 | 3 | 200 | i-lug |
Izicelo ze-Surge Protectors
Ngisanda kuthumela ama-pcs angu-1 200 e-UK. Azohlala kuma-data racks, emapulazini, nasophahleni lwesitolo esikhulu. Ingxenye efanayo, uhlobo olufanayo.
Ungasebenzisa i-SPD eyodwa ekhaya, esitshalweni, noma epulazini lomoya. Uma nje ulinganisa ama-volts nama-amps, ingxenye idla i-spike noma kuphi.
Izindawo Ezishisayo Esizisebenzelayo
- Izitolo ze-CNC eStuttgart
- Izitolo ezibandayo eMilan
- Imigwaqo ye-LED eLeeds
- Izimboni zerayisi eManila
Umthetho Owodwa Wabo Bonke
Gcina intambo imfushane. Ngaphansi kwama-50 cm ukusuka ku-breaker kuya ku-SPD. I-cm ngayinye eyengeziwe inezela i-10 nH ye-inductance futhi iphakamisa ama-volts avumelayo. Intambo emfushane, umthwalo ophephile.
Isiphetho
Iphaneli ye-SPD ingumshwalense oshibhile. Yilinganise kahle, uyifinyeze, bese ulala ngesikhathi isiphepho sifika. Ngithumelele i-imeyili ku-caroline@leikexing.com ukuze uthole ishidi lama-specs lamahhala kanye nesilinganiso samahora angu-24.
