Ingabe Isivikelo Sokukhuphuka Sizosebenza Ngaphandle Komhlaba?
Isivikelo sokukhuphuka kwamandla kagesi asikwazi ukusebenza kahle ngaphandle kokumisa igesi. Ukuze uthole isivikelo sangempela ekukhuphukeni kwamandla kagesi, qiniseka ukuthi indawo yakho yokukhipha amanzi imisa igesi futhi izintambo zakho zihambisana nekhodi.
Kungani Uhlelo Lwakho Lokuvikela Umbani Luphelele Ingxenye Kuphela Ngaphandle Kokuvikelwa Kwangaphakathi?
Idivayisi yobuchwepheshe yokuvikela ukukhuphuka (i-SPD) isebenza ngokusebenzisa izindlela zokudlulisa amandla ezigabeni eziningi kanye nezindlela zokubopha i-voltage. Embindini wayo, isebenzisa izingxenye ezifana nama-MOV nama-GDT ukuhambisa ngokushesha amandla okukhuphuka aye phansi futhi ibambe i-voltage esele ngaphakathi kwemingcele ephephile yemishini exhunyiwe. Ukusebenza kwayo kuncike kwikhwalithi yezingxenye, ubude be-lead yomhlaba, kanye nokuvikelwa okuhlanganisiwe kwezingqimba. Izinkomba zokusebenza ezibalulekile (ama-KPI) njenge-voltage yokubopha (Up) kanye nemijikelezo yokuphila kokukhuphuka kuqinisekisa ukuthembeka kwesikhathi eside.
Umhlahlandlela Wokuthenga Idivayisi Yokuvikela I-Surge: Amathiphu Ama-3 Ahlakaniphile Okukhetha Idili Langempela
Thola ukuthi ungayikhetha kanjani idivayisi yokuvikela ukukhuphuka okuthembekile (i-SPD) ngokuhlola izinqubo zokukhiqiza, izitifiketi, kanye nokuhlolwa kwelebhu — okubalulekile ekuphepheni kohlelo lukagesi.
Ukuvikelwa Kombani Wangaphakathi kanye Namadivayisi Okukhuphuka: Uyini Umehluko?
Ukuvikelwa kombani kwangaphakathi kugxile ekuvimbeleni izinhlansi eziyingozi ezibangelwa yimisinga yombani, ikakhulukazi ngokubopha okunamandla kanye nokufakwa komoya. Ukuvikelwa kombani kuhlose ukuvikela izinhlelo zangaphakathi ekukhuphukeni okubangelwa umbani kusetshenziswa ama-SPD ahlanganisiwe, ukuvikela, ukusekela phansi, kanye namasu okuzihlukanisa. Uchungechunge lwe-IEC 62305 luhlukanisa ngokucacile le mibono emibili, lapho i-SPM ibhekana nemiphumela yokwanda kanye ne-LPS yangaphakathi ibhekana nezingozi zombani. Zombili ziyizingxenye ezibalulekile zesu eliphelele lokuvikela umbani.
Ukukhethwa Kwamadivayisi Okuvikela Ukwanda Kwezinhlelo ze-PV - Ipharamitha ye-SPD
Lesi sihloko sichaza indlela yokukhetha ama-SPD afanele ohlangothini lwe-DC lwezinhlelo zelanga eziphahleni, sigcizelela isidingo samadivayisi athile e-PV ane-voltage efanele kanye nezilinganiso zamanje. Siphinde siveze ukuthi amanani ajwayelekile ayizilinganiso ezincane nje, ngakho-ke ukwakheka kwesistimu, ukusekelwa komhlaba, kanye nokuvikelwa kombani kufanele kucatshangelwe ngokucophelela.
Indlela Yokukhetha Ngokufanele Idivayisi Evikelayo Yokukhuphuka (i-SPD)
Ukukhethwa kwe-SPD kudinga ukuhlolwa okuphelele kwamandla kagesi esistimu, ingozi yombani, ikhono lokumelana nemishini, kanye nendawo yokufaka.
Ukukhetha Amadivayisi Okuvikela Ukwanda Kwezinhlelo ze-PV - Ukufakwa kwama-SPD
Ukukhiqizwa kwamandla e-Photovoltaic (PV) kuwumthombo oyinhloko wamandla avuselelekayo futhi kuya ngokuya kuncintisana uma kuqhathaniswa nokukhiqizwa kwamandla kwendabuko ngokombono wezomnotho. Phakathi kwezinhlobo ezahlukene zezicelo ze-PV, izinhlelo ezincane ezisatshalaliswayo—njengokufakwa kwe-PV ophahleni—yizona ezisetshenziswa kakhulu.
Izindlela Ezinhlanu Zokuvikela Abavikeli Bokukhuphuka
Kulinganiselwa ukuthi u-75% wokwehluleka kwemikhiqizo kagesi kubangelwa ukuguquguquka nokunyuka. Ukuguquguquka nokunyuka kwamandla kagesi kutholakala yonke indawo—kungakhathaliseki ukuthi kuvela kumagridi kagesi, ukushaya kombani, ukuqhuma, noma ngisho nesenzo sokuhamba ekhaphethini, okungakhiqiza amashumi ezinkulungwane zama-volts okufakwa kwamandla kagesi. Konke lokhu kuyizinsongo ezingabonakali kodwa ezibulalayo kumadivayisi kagesi.
Ngakho-ke, ukuze kuthuthukiswe ukuthembeka kwemikhiqizo kagesi nokuqinisekisa ukuphepha kwabantu, kumele kuqaliswe izinyathelo zokuvikela ezishintshashintshayo zama-voltage kanye nokunyuka kwawo.
Ukukhetha Amadivayisi Okuvikela Ukwanda Kwezinhlelo ze-PV - Izinhlobo ze-SPD
Izinhlelo ze-PV eziphezu kophahla zifaka phakathi ukusatshalaliswa kwamandla e-AC kanye ne-DC, kanye nama-voltage afinyelela ku-1500V. Ikakhulukazi, uhlangothi lwe-DC—njengamaphaneli e-PV—lungabonakala ngqo ezindaweni ezivame ukushaywa umbani, okwenza zibe sengozini enkulu yokulimala kombani. Ngisho noma amamojula e-PV engaphumeleli ukuvimbela ukufudumala ngaphansi kwe-overvoltage ebangelwa umbani, ukusebenza kwawo kagesi kungase kuqhubeke nokuwohloka. Lokhu kubeka izidingo eziphezulu ekuvikelweni kwe-overvoltage kwezinhlelo ze-PV eziphahleni.
Amapharamitha Abalulekile kanye nezindinganiso zokuhlola zamadivayisi okuvikela i-Surge (ama-SPD)
Idivayisi Evikela Ukukhuphuka (i-SPD): Idivayisi esetshenziselwa ukunciphisa ama-overvoltage esikhashana kanye nokuguqula ama-surge currents.
