Kodi Woteteza Wokwera pa Bokosi Lamagetsi Kuyambitsa Mavuto Kapena Kupereka Chitetezo?

Ndinaona kasitomala akutaya 30 K USD kamodzi kokha. Fungo la magalimoto oyaka limandidzutsabe usiku.

Choteteza ma surge chokhazikika pa panel sichimayambitsa mavuto ngati mutasankha voltage yoyenera ndikulola katswiri wovomerezeka kuyiyika. Chimadula spike isanachoke pansi pa mita, kuti makina anu akhale otetezeka.

Pansipa ndikukufotokozerani za kukayikira kulikonse komwe ogula ngati Jeff adanditumizira chaka chatha. Pitirizani kuwerenga ndipo mudzadziwa chifukwa chake timayika mabokosi ang'onoang'ono awa ku kabati iliyonse yomwe imachoka ku fakitale yathu ya Wenzhou.

Kodi Choteteza Kuthamanga pa Bokosi Lamagetsi ndi Chiyani?

Ndikukumbukirabe nthawi yoyamba yomwe ndinagwira imodzi. Inkaoneka ngati chodulira magetsi cholemera, koma chizindikirocho chinali ndi mawu akuti “SPD 40 kA”. Ndinafunsa bwana wanga kuti, “Kodi chinthuchi ndi chosinthira chapadera chabe?”

Choteteza mafunde amagetsi ndi chipangizo chachitsulo chomwe chimalumikiza mwachindunji ku basi yayikulu. Chimatenga kapena kusuntha magetsi owonjezera mumasekondi osakwana 25, kotero mphamvu yowonjezerayo sifika kwa ma breaker anu.

Momwe Zimasiyanirana ndi Power Strip

Ogula ambiri amasakaniza ziwirizi. Chingwe chamagetsi chili pafupi ndi desiki yanu ndipo chimakupatsani malo ambiri otulutsira magetsi. Chingwe cha SPD chili mkati mwa kabati yachitsulo ndipo chimateteza malo onse. Chingwecho chikhoza kuyima pa 1 kA. Chingwe chathu cha bokosi chimayamba pa 20 kA ndikukwera mpaka 200 kA. Kusiyana kumeneko kumakhala kwakukulu mphepo yamkuntho ikagwa.

Mkati mwa Bokosi

Tsegulani chimodzi ndipo muwona mabuloko atatu achitsulo. Buloko limodzi ndi varistor. Limadya spike. Buloko lachiwiri ndi chubu cha gasi. Limayaka pamene spike ili yayikulu kwambiri. Buloko lachitatu ndi fuse. Limafa kotero ena onse amakhala ndi moyo. Onse atatu amakhala pa njanji ya DIN ndipo amatenga malo atatu okha. Malo ang'onoang'ono amenewo amapulumutsa chomera chonse.

Manambala Enieni Ochokera ku Lab Yathu

Tinagunda spike ya 6 kV ku bolodi loyesera. Voltage yomwe inali kumbali ya katundu inali 420 V yokha pamene SPD inali kuyatsidwa. Popanda iyo, katundu womwewo unawona 2 850 V. Ma drive ambiri amalephera pa 1 800 V. Gome likuwonetsa kusiyana.

Kodi Chitetezo cha Surge Chimagwira Ntchito Bwanji?

Ndinkaganiza kuti ndi matsenga. Kenako mainjiniya athu anandionetsa graph imodzi yosavuta. Mzere wofiira ndi spike. Mzere wabuluu ndi clamp. Kumene zikumana, spike imafa.

Chipangizochi chimayang'ana mafunde a sine. Pamene magetsi akukwera pamwamba pa 1 100 V, amafupikitsa chingwecho kuti chigwe pansi kwa masekondi angapo. Mphamvu yowonjezerayo imasanduka kutentha mkati mwa varistor. Mafundewo amabwerera ku 230 V ndipo PLC yanu siwonanso kudumphako.

Magawo Atatu Omwe Timagwiritsa Ntchito ku Wenzhou

Timamanga magiredi atatu. Gawo loyamba limakhala pa mita. Gawo lachiwiri limakhala pa sub-panel. Gawo lachitatu lili pafupi ndi drive. Gawo lililonse limadya gawo la spike. Mwanjira imeneyi palibe gawo limodzi lomwe limalandira phindu lonse. Ogula ngati Jeff amasunga ndalama chifukwa amangosintha gawo loyamba pambuyo pa mphepo yamkuntho yayikulu.

Chifukwa Chake Speed ​​​​Beats Kukula

Varistor yayikulu imawoneka yamphamvu, koma liwiro limapambana. Chip yathu yatsopano ya 25 ns imaposa block yakale ya 100 ns ndi nthawi zinayi. Mpata umamveka wochepa, koma drive imatha kutseka 50 ns. Kuthamanga ndikotetezeka.

Kodi Zoteteza Kuthamanga Zimayambitsa Mavuto?

Mu Marichi watha, wogula ananditumizira imelo, “Jason, SPD yanu yatentha basi langa.” Ndinapita ku malo omwe ndinkagwiritsa ntchito ndipo ndinapeza woyikirayo akugwiritsa ntchito chipangizo cha 120 V pa chingwe cha 277 V. Chipangizocho chinafa ndipo chinatenga chipangizocho.

Choteteza ma surge sichingayambitse zolakwika ngati mukugwirizana ndi voltage, short-circuit current, ndi kukula kwa waya. 90% ya mavuto a m'munda amachokera ku kuyika kolakwika, osati gawolo.

Zolakwika Zitatu Zapamwamba Zomwe Timaziona

1. Voliyumu yolakwika. Gawo la 120 V pa mzere wa 240 V lidzayamba kugwira ntchito pakapita masiku.
2. Waya wosasunthika. Waya wa 2.5 mm² panjira ya 100 kA umasanduka wotentha kwambiri.
3. Palibe fuse. Gawo likafa, basi limakhalabe ndi moyo ndipo limasungunuka.

Momwe Timaletsera Zolakwa

Timayika chizindikiro chachikulu mbali zonse ziwiri. Chizindikirocho chikuwonetsa ma volts apamwamba ndi mphamvu mu N·m. Timatumizanso chogwirira chachitsulo cha fuse m'bokosi lomwelo. Wogula sangachidumphe.

Tebulo Lofufuzira Mwachangu la Jeff

Ubwino wa Chitetezo cha Kuthamanga pa Bokosi Losweka

Chaka chatha ndinayenda pansi pa fakitale ya ku Germany. Anali ndi ma drive 300 pa chipinda chimodzi. Manejala anandiuza kuti, “Jason, kugunda kamodzi kunapha ma drive 10. Popeza tinawonjezera SPD yanu, sitinatayepo chilichonse.”

Kuyika chotetezera pa bokosi lothyola madalaivala kumachepetsa nthawi yogwira ntchito, kumasunga mabolodi, komanso kumachepetsa ndalama zonse zomwe munthu amakhala nazo. Gawo limodzi la 40 USD likhoza kusunga 3,000 USD m'ma drive ndi masiku omwe munthu amataya nthawi yogwira ntchito.

Kumene Ndalama Zimapita

Kuyendetsa galimoto yatsopano kumawononga ndalama zokwana 1,200 USD. Katswiri wa zaukadaulo amawononga ndalama zokwana 80 USD pa ola limodzi. Tsiku lotayika limawononga ndalama zokwana 5,000 USD pa masiku omwe sitimayo sinafike. Tebulo lili ndi ndalama zonse.

Zopambana Zobisika

Makampani a inshuwaransi ku France tsopano akupereka kuchotsera kwa 5% ngati muwonetsa satifiketi ya SPD. 5% imeneyo ikuposa mtengo wa magawo chaka choyamba.

Kodi Mungasankhe Bwanji Choteteza Choyenera cha Bokosi Lanu Lamagetsi?

Jeff analemba kuti, “Ndikufuna ma PC 2 000, koma sindikudziwa nambala ya gawo.” Ndinamutumizira pepala limodzi. Iye anayankha ndi mzere umodzi, “Ndamaliza.”

Sankhani magetsi, mphamvu yayikulu, ndi mawonekedwe. Kenako yang'anani mtundu wa mchira. Chida cha njanji cha 40 kA 230 V DIN chokhala ndi mchira wa 6 mm² chikugwirizana ndi 80% ya ntchito.

Pepala Lotsatira Gawo ndi Gawo

1. Werengani ma volts a mzere. 230 V kapena 120 V kapena 277 V?
2. Werengani ma amplifier afupiafupi omwe ali pa main breaker. 10 kA kapena 50 kA?
3. Werengani magawo. Limodzi, logawanika, kapena atatu?
4. Sankhani fomu. DIN njanji kapena foot mount?
5. Sankhani mchira. Waya wa 6 mm² kapena lug ya 25 mm²?

Mapu a Khodi Yachangu

Kugwiritsa Ntchito Oteteza Odwala

Ndangotumiza ma PC 1,200 ku UK. Adzakhala pa malo osungira deta, m'mafamu, komanso padenga la malo ogulitsira. Gawo lomwelo, zomwezo.

Mungagwiritse ntchito SPD imodzi m'nyumba, pafakitale, kapena pafamu ya mphepo. Bola ngati mukugwirizana ndi ma volt ndi ma amp, gawolo limadya mphamvu ya spike kulikonse.

Malo Otchuka Amene Timatumikira

- Masitolo a CNC ku Stuttgart

- Masitolo ozizira ku Milan

- Misewu ya LED ku Leeds

- Mafakitale a mpunga ku Manila

Lamulo Limodzi kwa Onse

Sungani waya waufupi. Pa mtunda wosakwana 50 cm kuchokera pa chopachikira kupita ku SPD. Cm iliyonse yowonjezera imawonjezera 10 nH ya inductance ndikukweza ma volts olowetsa. Waya waufupi, katundu wotetezeka.

Mapeto

Chida cha SPD ndi chotsika mtengo. Chikulitseni bwino, chifupikitseni, ndipo mudzagona pamene mphepo yamkuntho ikugwa. Nditumizireni imelo ku caroline@leikexing.com kuti mupeze pepala laulere la specs ndi mtengo wa maola 24.
