Kwiinkqubo zamandla zanamhlanje kunye nezixhobo ze-elektroniki, ii-surge protectors (ii-SPD) kunye nee-inverters, njengezinto ezimbini ezibalulekileyo, ukusebenza kwazo ngokubambisana kubalulekile ekuqinisekiseni ukusebenza okukhuselekileyo nokuzinzileyo kwenkqubo yonke. Ngophuhliso olukhawulezayo lwamandla ahlaziyekayo kunye nokusetyenziswa ngokubanzi kwezixhobo ze-elektroniki zamandla, ukusetyenziswa okudibeneyo kwezi zimbini kuye kwanda kakhulu. Eli nqaku liza kujonga kwimigaqo yokusebenza, iikhrayitheriya zokukhetha, iindlela zokufakela ii-SPD kunye nee-inverters, kunye nendlela ezinokudityaniswa ngayo ngokugqibeleleyo ukubonelela ngokhuseleko olupheleleyo kwiinkqubo zamandla.

Kwiinkqubo zombane zanamhlanje, izixhobo zokukhusela i-surge (ii-SPD) zidlala indima ebalulekileyo. Nokuba kusemakhaya, kwiifektri, kumaziko edatha okanye kwizikhululo zonxibelelwano, ii-SPD zinokukhusela ngokufanelekileyo kwi-overvoltages ezidlulayo ezibangelwa kukubetha kombane, ukuguquguquka kwegridi yamandla kunye nezinye izinto, ukuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo. Eli nqaku liza kwazisa inkcazo, umgaqo wokusebenza, indlela yokukhetha kunye nesikhokelo sokufakela ii-SPD ngokweenkcukacha, kwaye sixoxe ngokubaluleka kwazo kwiimeko ezisebenzayo. Ukongeza, siza kuhlalutya nemiphumo emibi enokwenzeka ukuba akukho SPD.

Ngowama-2024, ilahleko ethe ngqo kwezoqoqosho ebangelwe kukubethwa ngumbane kwihlabathi liphela ifikelele kwi-4.7 yeebhiliyoni zeerandi zaseMelika, phantse i-60% yale lahleko ibangelwa kukungakhuseleki ngokwaneleyo kweenkqubo zombane. Njengesixhobo esibalulekileyo sokumelana nokunyuka kwamandla ombane, umgangatho wokufakelwa kwezixhobo zokukhusela amandla ombane (ii-SPD) umisela ngokuthe ngqo ukuthembeka kwenkqubo yonke yamandla. Eli nqaku liza kujonga kwiimfihlo zokufakelwa kwale "power guardian", likukhokele kwisisombululo esibanzi ukusuka kumgaqo ukuya kwisicelo esisebenzayo.

Umthamo we-photovoltaic ofakelweyo kwihlabathi liphela udlule kwi-350GW kunyaka ophelileyo, apho iTshayina inegalelo elingaphezulu kwesinye kwisithathu. Le teknoloji eluhlaza eguqula ukukhanya kwelanga kube ngumbane ibone iindleko zayo zihla ngama-80% kwiminyaka elishumi, kodwa ijongene nosongelo olubulalayo lokubetha kombane - isikhululo samandla eArizona, eMelika, esakha salahlekelwa yi-$2 yezigidi ngenxa yokubetha kombane. Izikhuseli zombane ziye zaba "yinto esindisa ubomi" yezikhululo zamandla, zikhokelela amashumi amawaka ee-volts zombane emhlabeni ngenethiwekhi yokukhusela enamanqanaba amathathu. Iingcali zoshishino zibonise ukuba njengoko i-voltage yeenkqubo ze-photovoltaic inyuka iye kwi-1500V, izixhobo zokukhusela zizisa utshintsho lobuchwepheshe kwizinto ze-silicon carbide.

Ukususela ekufakweni ukuya ekulungisweni, ezi nkcukacha akufuneki zityeshelwe

Kwiinkqubo zamandla zanamhlanje, izikhuseli ze-surge (SPD) zifana "nepolisi yomshuwalense" kwizixhobo ze-elektroniki. Kodwa ubusazi? Esi sixhobo sibonakala silula, ukuba sifakwe okanye sisetyenziswa ngendlela engafanelekanga, asipheleli nje ekunikezeni ukhuseleko kodwa sinokuba yingozi kukhuseleko. Namhlanje, masithethe ngezinto eziluncedo nezingalunganga zokusebenzisa ii-SPD.

Njengoko amandla okufakelwa kwe-photovoltaic kwihlabathi liphela edlula uphawu lwe-1TW, ukuthembeka kwenkqubo kunye nemiba yokhuseleko iya isanda. Ngokwezibalo zamva nje ezivela kwiKomiti yoBugcisa ye-International Electrotechnical Commission (IEC) TC82, ukusilela kwenkqubo yombane kubangela ukuya kuthi ga kwi-41.3% yokusilela kokusebenza nokugcinwa kwezikhululo zamandla ze-photovoltaic, apho umonakalo wezixhobo obangelwe kukugqithisa kwamandla okwethutyana ubangela i-28.7% yokusilela konke. Le meko ibaluleke kakhulu kwiindawo ezishushu nezishushu ezineemvula ezininzi.

Ngenxa yophuhliso olukhawulezileyo lweshishini le-photovoltaic lehlabathi, ukhuseleko kunye nokuzinza kweenkqubo zokuvelisa umbane welanga kuye kwaba yinto ephambili kwishishini. Iinkqubo ze-photovoltaic zibonakala ngaphandle ixesha elide kwaye zisengozini yezisongelo ezifana nokubetha kombane, ukuguquguquka kwegridi yamandla, kunye nokusilela kwezixhobo, okunokubangela umonakalo kwizixhobo okanye kwanomlilo. Izikhuseli zokushushuba (ii-SPD), izaphuli zesekethe, kunye neefusi zizixhobo zokukhusela eziphambili ezithi nganye zenze imisebenzi yayo kwaye zisebenzisane ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo. Eli nqaku liza kuhlalutya ngokunzulu imisebenzi yazo, iindlela zokulungelelanisa, kunye nemfuneko yokubonelela ngereferensi kubasebenzisi beli shishini.

Kutheni Izixhobo Zakho Zifuna "iVoltage Bodyguard"?

Khawucinge ngoku: Ngobusuku obunesaqhwithi obunemibane edlula esibhakabhakeni, izixhobo zakho zobuchule ezixabisa amakhulu amawaka ngequbuliso "ziya kubetha." Lo asingomboniso wefilimu eyoyikisayo kodwa liphupha elibi kakhulu eliye lajongana neefektri ezininzi kunye nemizi. Isixhobo sokukhusela i-surge (SPD) "siqhawe" kweli bali—esikwaziyo ukukhawulezisa ii-voltage eziyingozi kwisiqingatha sesibini somzuzwana. Kodwa nantsi into ebambekayo: abantu abaninzi bazisa lo "mlindi" ekhaya bengazi ukuba bayisebenzise njani ngokufanelekileyo.

Namhlanje, masithethe ngalo mlindi wokhuseleko lombane obonakala ulula kodwa untsonkothile kakhulu.

Kwihlabathi lanamhlanje eliqhutywa bubuchwepheshe, izixhobo zombane neze-elektroniki zisengozini enkulu kunangaphambili yokonakala ngenxa yokunyuka kwamandla okubangelwa kukubethwa ngumbane, ukuguquguquka kwegridi, okanye imisebenzi yokutshintsha kwangaphakathi. Izixhobo zokukhusela ukuxhuzula, ezaziwa ngokuba zizixhobo zokukhusela ukuxhuzula (ii-SPD), zidlala indima ebalulekileyo ekukhuseleni izixhobo ezibuthathaka kwi-voltage spikes. Eli nqaku liphonononga ukusetyenziswa okusebenzayo kwezikhuseli zokuxhuzula kumashishini ahlukeneyo kwaye libonisa ukusebenza kwazo ngezifundo zamatyala.

Intshayelelo

Izikhuseli zoxinzelelo lomoya (ii-SPD) zizinto ezibalulekileyo kwiinkqubo zombane zokunciphisa i-overvoltages ezidlulayo kunye ne-shunting surge currents. Zisetyenziswa kakhulu kwiinkqubo zamandla ombane ngqo (DC) kunye neenkqubo zamandla ombane atshintshanayo (AC). Ngenxa yeempawu ezahlukeneyo zezikhuseli zoxinzelelo lomoya ze-DC kunye nezikhuseli zoxinzelelo lomoya ze-AC, izikhuseli zazo zoxinzelelo lomoya zahlukile kakhulu kwisakhiwo, umgaqo wokusebenza, kunye neemeko zesicelo. Eli nqaku liza kuhlalutya ukufana kunye nomahluko phakathi kwezikhuseli zoxinzelelo lomoya ze-DC kunye nezikhuseli zoxinzelelo lomoya ze-AC ngokweenkcukacha, kwaye linike iingcebiso zokukhetha.
