Isifundazwe saseBinh Duong eVietnam sinokushisa okuphezulu okungapheli, umswakama ophezulu kanye nenkungu kasawoti omningi, okuletha izimo zokusebenza ezinzima ezibangela izinselele ezinkulu emishinini yokusabalalisa amandla e-photovoltaic. UNguyễn Minh Trung, unjiniyela oneminyaka engu-36 ubudala onolwazi lweminyaka engu-8 ekusebenzeni nasekulungiseni amandla amasha endawo, unesibopho sokuhlolaIzinhlelo zokusabalalisa amandla ze-DCzeziteshi zikagesi ze-photovoltaic zesifunda.
Emini lapho izinga lokushisa lenyuka laya ku-42℃, kwaqubuka i-short circuit engazelelwe egumbini lokusabalalisa ugesi leNombolo 2 ngesikhathi sokuhlola kwakhe okuvamile. Ihambisana nephunga likagesi elishile, i-DC busbar yakhubeka ngokushesha futhi sonke isiteshi sikagesi se-photovoltaic samisa ukukhiqizwa kukagesi. Uphenyo lwembule ukuthi iphrojekthi yasebenzisa ama-DC circuit breakers angabizi kakhulu ukuze kuncishiswe izindleko zokuqala. Ngemva kwezinyanga ezimbili nje zesevisi, isimo sezulu esibi sendawo sabangela ukuguga kokushisa kanye nokwehluleka kokuxhumana, okwabangela i-short circuit ye-DC enzima. Kunzima ukuyicima, i-DC electric arc eqhubekayo yacishe yabangela umlilo kagesi.
Ukucima kukagesi kuthathe izinsuku ezine, okwaholela ekulahlekelweni okukhulu kwemali engenayo yokukhiqizwa kukagesi, kanye nezindleko ezengeziwe emsebenzini wokushintsha imishini nokulungisa. UNguyễn Minh Trung ukhombe ukuthi izimo zokusebenza ezinzima ziyinselele enkulu kumaphrojekthi okugcina amandla kagesi kanye nokugcina amandla eVietnam. Imishini ephansi engabizi kakhulu ayizivumelanisi nezimo ezimbi kakhulu, okwenza ukuphepha nokuqina kube yinto eza kuqala kumaphrojekthi amasha endawo.
Yakhelwe kuphela izinhlelo zokusebenza zamandla amasha ze-DC ezinamandla aphezulu,Ama-circuit breaker e-DC abunjwe ngochungechunge lwe-RDM8DC(DC MCCB) ivumelana kahle nezimo zokusebenza ezinzima neziyinkimbinkimbi zaseVietnam, ixazulula ngempumelelo izingozi zokuphepha kokusatshalaliswa kwamandla ezindaweni zokugcina i-photovoltaic kanye namandla endawo.
Ingxenye 1: Amandla Avuselelekayo Achumayo eNingizimu-mpumalanga ye-Asia Kwenza Ukuvikelwa Kokusabalalisa kwe-DC Kubaluleke Kakhulu
INingizimu-mpumalanga ye-Asia isibe ngenye yezimakethe zamandla avuselelekayo ezikhula ngokushesha emhlabeni jikelele. Amazwe afaka phakathi iVietnam, iMalaysia, iPhilippines kanye ne-Indonesia asethule izinqubomgomo ezisekelayo zokugcina amandla elanga kanye nokugcina amandla. Njengoba ibhekene nokushoda kwamandla kanye nengqalasizinda yegridi yamandla engaphelele, izimboni zamandla amasha zesifunda zibona intuthuko enkulu.
Izuza ngemithombo eminingi yokukhanya kwelanga, amapaki amaningi ezimboni kanye nezinqubomgomo zikahulumeni ezinhle, iVietnam ibekwe phambili ekukhuleni kokufakwa kwesitoreji selanga kanye namandla kulo lonke elaseNingizimu-mpumalanga ye-Asia. Amaphaneli elanga ophahleni, iziteshi zelanga ezifakwe phansi, izinhlelo zokugcina amandla ezentengiselwano kanye namagridi kagesi amancane angaphandle kwegridi kungabonakala ezweni lonke. Izibalo zibonisa ukuthi iNingizimu-mpumalanga ye-Asia izofinyelela umthamo welanga osanda kufakwa ongaphezu kuka-30GW ngo-2026, kanti iVietnam icishe ibe ngu-40% wenani eliphelele. Izinga lokukhula kwemakethe yokugcina amandla lidlula u-100%, kanti umthamo omusha ongeziwe uzofinyelela cishe ku-100GWh eminyakeni emine ezayo.
Uhlelo lwamandla e-DC olusebenzisa i-voltage ephezulu oluvela ku-250V kuya ku-1500Vsekuyinto esetshenziswa kakhulu kumaphrojekthi wamandla avuselelekayo esimanje. Isetshenziswa kabanzi ekuhlanganisweni kwe-solar array, ekukhishweni kwe-battery cluster, ekuxhunyweni kwe-inverter DC ohlangothini kanye nokusatshalaliswa kwamandla e-EV charging pile. Ukudluliselwa kwe-DC enamandla aphezulu kunciphisa ngempumelelo ukulahleka kwamandla ekhebula futhi kuthuthukisa ukusebenza kahle kwesistimu iyonke. Noma kunjalo, futhi kuletha izingozi ezifihliwe ezivelele:
✔️ I-arc ye-DC ayikwazi ukucima ngokwemvelo, okwandisa kakhulu izingozi zokusha kwemishini kanye nomlilo kagesi okubangelwa yi-short circuit;
✔️ Izinga lokushisa laseVietnam liyahlukahluka kusuka ku--5℃ kuya ku-50℃, okuhambisana nezinkathi zemvula ezinde kanye nokugqwala kwenkungu kasawoti ogwini, okubeka izidingo eziqinile zokuvikela ukushisa, ukumelana nokushisa okuphezulu kanye nokusebenza kokulwa nokugqwala kwe-DC MCCB;
✔️ Ukushintshashintsha kwamanje okuvamile kuholela kalula ekucindezelekeni ngokweqile kanye namaphutha esigungu esifushane, okudinga ama-circuit breaker anokusebenza okuqondile kokuvikela kanye nomthamo oqinile wokuphuka;
✔️ Izimo zephrojekthi ezahlukahlukene zidinga ukwakheka okuguquguqukayo ngenombolo yesigxobo, imodi yokusebenza kanye nokufakwa kwezintambo.
Ama-AC circuit breaker endabuko kanye nama-DC protective switch aphansi awakwazi ukuhlangabezana nezidingo ezingenhla. Ngokuvamile anokumelana nogesi okwanele kanye nomthamo obuthakathaka wokuphuka kwe-short-circuit, ehluleka ukucima i-arc kagesi ngesikhathi esifanele ngesikhathi samaphutha. Ukumelana nokushisa nomswakama okungekuhle nakho kuholela ekungasebenzi kahle njalo kanye nokusebenza okungasebenzi kahle ngaphansi kwesimo sezulu esinzima saseVietnam. Umsebenzi wokuvikela owodwa wenza le mikhiqizo ingakwazi ukuvikela amagridi kagesi e-DC ngokuphelele.
Ukusatshalaliswa kwamandla e-DC okungaphephile sekuyinkinga enkulu evimbela ukusebenza okuzinzile kanye nokugcinwa okungabizi kakhulu kwamaphrojekthi wamandla avuselelekayo aseVietnam. I-RDM8DC high voltage DC molded case circuit breaker yenzelwe ukubhekana nalezi zinselele, ifanelana kahle nezidingo zokusebenza kwamandla elanga, isitoreji samandla kanye namaphrojekthi okusabalalisa e-DC eVietnam naseNingizimu-mpumalanga ye-Asia.
