Unoda Mudziviriri weKuputika Here?
Ndichiri kurangarira kunhuhwirira kwepurasitiki yakatsva apo inverter yemutengi yakakangwa muna 2019. Kukwiza kumwe chete ikoko kwakamutorera 28 000 USD uye mavhiki matanhatu ekushanda.
Ehe, unoda dziviriro yekuputika.Kurova kamwe chete kwemheni kana kukanganisa grid kunogona kutumira zviuru zvemavolts muwaya dzako. SPD inodya spike iyoyo isati yasvika pa inverter yako, mita, kana bhatiri. Ndakaona ichichengetedza denga rese rezuva.
Hausati wava nechokwadi here? Ramba uchiverenga. Ndichakuratidza kukuvara chaiko, nhamba chaidzo, uye zvirevo chaizvo zvatinoshandisa patinotumira kuBerlin kana kuMilan.
Chii Chinoitika Pasina Mudziviriri weKuputika?
Ndakavhura chivharo chesimbi uye PCB yaitaridzika kunge black toast. Mutengi akafunga kuti inishuwarenzi yaizobhadhara. Hazvina kudaro.
Pasina SPD, kukwira kwemagetsi inokwira zvakananga mu inverter yako.DC link capacitor inoputika, maIGBT anopfupika, uye tambo yese inomira. Imwe spike ye1 500 V inogona kudzima inverter ye50 000 USD mumasekonzi 0.2.
Kuongororwa Kwemutengo Chaiko
| DamagePoint | Mutengo Wakajairika (USD) | Nguva Yekutungamira | Mari Yakavanzwa |
| Inverter ye100 kW | 28,000 | Mavhiki 8–12 | Kurasika kweFit |
| bhatiri re20 kWh | 14,000 | Mavhiki matanhatu | Isazve |
| Kurasikirwa kwekugadzirwa | 4,200 / vhiki | – | Zvikamu zvechirango |
Sei Muputsi Asina Kugumburwa
Mabreaker anongopindura chete kana magetsi akawandisa, kwete magetsi akawandisa. Spike inogona kuva 2 000 V asi 3 A chete, saka breaker inonyemwerera yoramba yakavharwa. Ndosaka uchida mudziyo unotarisa magetsi, kwete magetsi. SPD inoita izvozvo chaizvo: inopfupisa mavolts ekuwedzera kupasi yobva yatangazve.
Ngano nhatu dzandinonzwa vhiki rega rega
- "Mapaneru angu adzika pasi."
Kuisa pasi kunoderedza voltage yekubata, asi hakubati spike.
- "Hatimbooni mheni pano."
Kuchinja grid, capacitor banks, uye kunyange motors dze elevator dzinoita spikes zuva nezuva.
- "Inverter iyi ine dziviriro yakavakirwa mukati."
MaMOV mazhinji emufekitori ane saizi ye40 J. Kurova zvakananga kunotakura 50 000 J. Masvomhu acho anosuwisa.
Nyaya kubva kuHamburg, Kurume 2023
Denga re2 MW rakanga risina SPD yekunze. Kurova kuri kure kwakakonzera 1 200 V patambo yeDC. Inverter yakafa, asi zvakatoipa, arc yakapwanya denga repolymer. Mvura yakapinda, uye kambani yeinishuwarenzi yakati "hapana kugadziriswa." Kubhadhara: zero. Mutengi akazotenga 120 ye1 000 V DC SPDs dzedu kuti dzivakwezve.
Dambudziko rekupisa rakavanzika
Mainjiniya mazhinji anokanganwa kuti SPD inogara mubhokisi diki reIP65 zuva rese. Zuva rinopisa simbi kusvika 70 °C. Mukati, MOV disk inomhanya zvakanyanya. Madhisiki akachipa anotanga kubuda magetsi pa85 °C. Kana mvura yatanga kubuda, kupisa kunokwira, magetsi anokwira, uye dhisiki rinotsemuka. Fekitori yedu inowedzera thermal snap-link inodhonza SPD offline pa120 °C. Chishandiso chinokundikana zvakachengeteka, kwete kupfupika, uye webhusaiti yako inoramba ichishanda.
Kurasikirwa neChiratidzo vs. Njodzi yeMoto
Vamwe vatengi vanongotarisa huwandu hwekudzivirira magetsi chete. Iniwo ndinotarisa kuchengetedzeka kwemoto. Muna 2021 imba yekuchengetera zvinhu muNetherlands yakatsva nekuti SPD isina zita yakabatira moto mushure mekunge MOV yakundikana. Inishuwarenzi yakaramba kubhadhara nekuti SPD yakanga isina UL 1449 4th Ed. rondedzero. Tinoedza batch yega yega yeIEC neUL kuitira kuti mugone kurara husiku.
Maitiro Ekusarudza Chidziviriro Chakakodzera Chekudzivirira Kuputika Kwemapurojekiti Ezuva
Gore rapera mumwe mutengi akanditumira RFQ yemapeji makumi maviri. Mutsetse wekutanga waiti: “SPD yakachipa, 1 000 pcs.” Ndakadzima email yacho.
Enzanisa SPD nevoltage yesystem yako, short-circuit current, uye njodzi.Tanga neIEC 61643-31. Sarudza voltage yeUc 20% pamusoro pevoltage yako yakavhurika. Wobva watarisa Imax: 40 kA yedenga remba, 100 kA yehukuru hwemagetsi. Ndinogara ndichiwedzera contact iri kure kuti timu yeSCADA ione rwendo.

Mashoko Akavanzika: Kubuda Kwekupisa
MaMOV blocks akachipa anotanga kudonha pa85 °C. Mukati mebhokisi dema reIP65 padenga reSpain, izvozvo zvinoitika zhizha rega rega. Mablocks edu anoshandisa thermal disconnect iyo inodonha pa120 °C. SPD inokundikana yakachengeteka, kwete pfupi.
Chikanganiso cheKureba kweLead
Ndinoona vanoisa ma "leads" anoshandisa 30 cm nekuti inokurumidza. Izvi zvinowedzera 300 V ku "let-through voltage". Mutemo wedu: chengeta ma "leads" ari pasi pe15 cm, kana kuatenderedza kuti adzime inductance. Mumwe mutengi akacheka ma "leads" kubva pa25 cm kusvika pa10 cm ndokuona achikwira kubva pa1.6 kV kusvika pa1.1 kV. Inverter yake yakapona dutu rakatevera.
Kubatana neAC Side
Usakanganwa nezve AC side. Kana inverter yachinja kuita 400 V AC, uchiri kuda SPD. Tinoisa mayuniti eClass II 275 V AC pabhodhi guru. Kune nzvimbo dzine ma transformer, tinowedzera Class I 25 kA 10/350 µs padivi reLV. Kurova kamwe chete pamutsetse weMV kunogona kuramba kuchidzika.
Nei MaEPC Akanakisisa Achishandisa Magadzirirwo eHybrid SPD
Ndakashanyira EPC yepamusoro gumi muMilan. Mainjiniya wavo akachinja SPD ndokuti: "Handidi MOV soup mufekitori yangu."
Hybrid SPDs inobatanidza chubhu yegesi inokurumidza ine MOV yakasimba. Chubhu yegesi inotora 90% yekutanga yekurova, saka MOV inoramba yakadzikama. Mhedzisiro: hupenyu hunowedzera katatu, let-through voltage inodonha ne30%. Ndosaka Tier-1 EPCs yava kunyora kuti "hybrid chete" muBoQ yavo.
