Umhlahlandlela we-DC kanye ne-AC SPD Uhlobo 2 wezinhlelo zelanga kanye nogesi

Ngibone isenzakalo esisodwa sokwanda kwesimo sezulu siqeda izinyanga zokukhiqiza, ngakho-ke ngihlala ngiphatha Idivayisi Evikelayo Yokukhuphuka njengento eyinhloko yokuklama, hhayi isesekeli sokuzikhethela.

Umhlahlandlela we-DC kanye ne-AC SPD Type 2 uchaza ukuthi kanjani Idivayisi Evikelayo Yokukhuphuka izixazululo zivikela izinhlelo zelanga kanye nezikagesi ekushiseni ngokweqile kwesikhashana, zithuthukise isikhathi sokusebenza, futhi zinciphise izindleko zokulungisa nokufaka esikhundleni isikhathi eside.

Uma ukhathalela ukulethwa okubikezelwayo, ikhwalithi ezinzile, kanye nezindleko eziphansi zobunikazi, ukuqonda ama-SPD ohlobo lwesibili yindawo ehlakaniphile yokuqala.

Iyini Idivayisi Yokuvikela Ukukhuphuka Kwe-DC

Ngivame ukubona izingozi ze-DC zinganakwa kuze kube yilapho imishini ihluleka, ngakho-ke ngihlala ngiqala ukubuyekezwa kwesistimu ohlangothini lwe-DC.

A Idivayisi yokuvikela ukukhuphuka kwe-DC Kunciphisa ukudlula kwamandla kagesi okwesikhashana kumasekethe e-DC ngokuphambukisa amandla okukhuphuka komhlaba ngokuphephile aye phansi, kuvikela imishini exhunyiwe ekulimaleni.

Ngibheka ukuvikelwa kokuqhuma kwe-DC njengengqimba yokuqala yokuzivikela ezinhlelweni zamandla elanga nezezimboni. Amasekethe e-DC ayabonakala, amade, futhi avame ukufakwa ngaphandle. Lokho kuwenza abe sengozini enkulu yokuqhuma okubangelwa umbani kanye nama-transient ashintshayo. Idivayisi Evikelayo Yokukhuphuka efakwe ohlangothini lwe-DC isabela ngaphakathi kwamasekhondi amancane futhi ibambe ama-voltage spikes ayingozi ngaphambi kokuba afinyelele kuma-electronics abucayi.

Ekufakweni kwangempela, ama-DC SPD avikela ama-inverter, izinsiza zikagesi ze-DC, amabhethri, kanye namasekethe okulawula. Ngaphandle kwawo, ukukhuphuka okukodwa kungabangela ukuphuka kokushisa, ukwehluleka kwe-semiconductor, noma ukuwohloka kokusebenza okungapheli. Ngikubonile lokhu kwenzeka ekuvikelweni kokukhuphuka kwamafektri lapho isikhathi sokungasebenzi siphenduka ngokushesha sibe izinsuku zokugcina zokulethwa ezingafikanga.

Umklamo omuhle we-DC SPD uhlala ubheka ikhwalithi yokumisa phansi, ubude bekhebula, kanye nendawo yokufaka. Angikaze ngiphathe ukuvikelwa kwe-DC njengengxenye ezimele. Kumelwe kusebenze njengengxenye yalo lonke uhlelo lokumisa phansi kanye nokubopha.

Uhlobo 2 lwe-DC SPD kwezinhlelo zelanga kanye nezamandla

Ngincoma ama-SDP e-Type 2 DC ezindaweni eziningi zokusatshalaliswa kwelanga kanye namandla.

Amadivayisi e-DC SPD Type 2 aklanyelwe ukuvikela izinhlelo ze-DC ekukhuphukeni kombani okubangelwa kanye nokushintshashintsha kwama-voltage ekufakweni kwezinga lokusabalalisa.

Kumaphrojekthi ami, ama-SDP ohlobo lwesibili yisisombululo esisetshenziswa kakhulu. Afakwa ngaphansi kohlelo oluyinhloko lokuvikela umbani futhi aphatha imicimbi ephindaphindayo yokuqhuma ngempumelelo. Ngokungafani namadivayisi ohlobo lwe-1, alungiselelwe amabhodi okusabalalisa, amabhokisi okuhlanganisa, kanye nokufakwa kwe-inverter.

Ngithanda ukuvikelwa kohlobo 2 kwe-solar yophahla, i-PV yezentengiselwano, kanye nezinhlelo zokusebenza eziningi ze-SPD zezimboni. Zinikeza ibhalansi eqinile phakathi kwezinga lokuvikelwa kanye nezindleko. Lokhu kubalulekile kubaphathi bokuthenga abafuna amanani abikezelwayo ngaphandle kokulahla ukuthembeka.

Ngokwalokho okwenzekile, ama-SDP ohlobo lwesibili e-DC anciphisa kakhulu amaphutha e-inverter aphazamisayo kanye nokuvalwa okungachazeki. Aphinde andise isikhathi sokuphila kwemishini ngokunciphisa ukucindezeleka kukagesi okuhlanganayo. Lokho kuholela ngqo ezindlekweni zokulungisa eziphansi kanye nokuzinza okungcono kwesistimu.

Kuchazwe Izilinganiso Ze-voltage ze-DC SPD

Ngibona amaphutha okulinganisa i-voltage kaningi kunanoma yiliphi elinye iphutha lokukhetha i-SPD.

Izilinganiso zama-voltage e-DC SPD kumele zidlule i-voltage ephezulu kakhulu yesistimu ye-DC ukuze kugwenywe ukwehluleka kusenesikhathi kanye nokulahlekelwa ukuvikelwa.

Angikaze ngikhethe i-SPD ngokusekelwe ku-voltage ejwayelekile kuphela. Izinga lokushisa, izimo zokusebenza, kanye nokwandiswa kwesistimu konke kuthinta amazinga e-voltage yangempela. Isibonelo, isimo sezulu esibandayo singacindezela i-voltage ye-PV evulekile kakhulu ngale kwamanani e-nameplate.

Nansi indlela engivame ukufanisa ngayo izilinganiso ze-DC voltage:

Ukusebenzisa isilinganiso se-voltage esifanele kuqinisekisa Idivayisi Evikelayo Yokukhuphuka isebenza ngokwethembeka ngokuhamba kwesikhathi esikhundleni sokwehluleka buthule ngemva kwemicimbi embalwa.

Ukucushwa kwePole kwamadivayisi okuvikela i-DC Surge

Ngihlala ngiqinisekisa ukucushwa kwepole ngaphambi kokuvuma noma iyiphi i-DC SPD.

Ukucushwa kwensika yokuvikela ukukhuphuka kwe-DC kuchaza ukuthi zingaki izikhombisi ezivikelwe kanye nendlela amandla okukhuphuka akhishwa ngayo emhlabathini.

Izinhlelo eziningi zelanga zisebenzisa ama-2P DC SPD ukuvikela ama-conductor amahle nangalungile. Ezinhlelweni eziyinkimbinkimbi kakhulu, izindlela ezahlukene zokubeka phansi zingadinga izigxobo ezengeziwe. Ukukhetha ukucushwa okungalungile kungashiya ingxenye yesistimu iveziwe.

Kumaphrojekthi e-SPD yezimboni, ngihlola kabili i-topology yokumisa isisekelo kuqala. Lokho kuvimbela izingozi ezifihliwe futhi kuqinisekise ukusebenza kokuvikela okuqhubekayo.

Iyini Idivayisi Yokuvikela Ukuqhuma Kwe-AC

Ngibheka ukuvikelwa kwe-AC njengesendlalelo sesibili esibalulekile sokuvikelwa.

I-An Idivayisi yokuvikela ukukhuphuka kwe-AC ikhawulela ukudlula kwamandla kagesi okwesikhashana emigqeni kagesi ye-AC, ivikela imithwalo kanye nemishini yokusabalalisa ekulimaleni.

Ama-AC SPD avikela ekukhuphukeni kwamandla angena esuka kugridi noma akhiqizwe ngaphakathi ngokushintsha izehlakalo. Ezinhlelweni zelanga, avikela okukhiphayo kwe-inverter, ama-switchboard, kanye nemithwalo engezansi.

Ngihlala ngihlanganisa ama-AC nama-DC SPD ndawonye. Ukuvikelwa okuhlukanisiwe akusebenzi kahle njengendlela yesistimu ehlelekile.

I-AC SPD Yezinhlelo Zesigaba Esisodwa Nezigaba Ezintathu

Ngilungisa ukukhetha kwe-AC SPD ngokusekelwe ku-topology yesistimu.

Ama-SPD e-AC akhethwa ngokuya ngokucushwa kwesigaba ukuqinisekisa ukuvikelwa kokuphakama okulinganiselayo nokuphelele.

Izinhlelo zesigaba esisodwa zivame ukusebenzisa ukucushwa okulula, kuyilapho izinhlelo zesigaba ezintathu zidinga izindlela zokuvikela eziyinkimbinkimbi kakhulu. Ngigxila ekulinganisweni nasekusekelweni ukuze ngigweme ukucindezeleka okungalingani ngesikhathi semicimbi yokwanda kwamandla kagesi.

Le ndlela isebenza kahle kakhulu ekuvikeleni ukukhuphuka kwemithwalo emafektri lapho ibhalansi yomthwalo kanye nokuqhubeka kwayo kubalulekile.

Izilinganiso ze-AC SPD Voltage kanye nokucushwa

Ngihlala ngifanisa izilinganiso ze-AC voltage nezimo zokusebenza zangempela, hhayi amalebula kuphela.

Izilinganiso ze-AC SPD voltage kanye nokucushwa kuchaza ukuthi ukukhuphuka kwamandla kuvalwa kanjani ngempumelelo ezinhlelweni zokuhlala, zezentengiselwano, kanye nezezimboni.

Nasi ireferensi elula engivame ukuyisebenzisa:

Ukucushwa okulungile kuqinisekisa ukuphambuka okuthembekile kokukhuphuka futhi kuvimbela ukuguga kwe-SPD ngaphambi kwesikhathi.

Ukuxhumanisa i-AC kanye ne-DC SPD ezinhlelweni zelanga

Ngihlala ngiklama ukuvikelwa kokukhuphuka njengohlelo oluhlelekile.

Ukusebenzisa ama-AC nama-DC SPD ndawonye kudala ukuvikelwa okunezingqimba okunciphisa i-voltage eseleyo futhi kuthuthukise ukuthembeka kwesistimu iyonke.

Ukuhlanganisa kusho ukubeka ama-DC SPD eduze kwama-PV arrays nama-inverter, kanye nama-AC SPD ezindaweni zokusabalalisa. Le ndlela ehlanganisiwe ijwayelekile ekwakhiweni kobuchwepheshe bokuvimbela ukukhuphuka futhi iletha ingozi ephansi yesikhathi eside.

Isiphetho

Khetha okulungile Idivayisi Evikelayo Yokukhuphuka isu manje lokuvikela uhlelo lwakho, isimiso sakho, kanye nokutshalwa kwezimali kwakho kwesikhathi eside.

Imibuzo Evame Ukubuzwa

Umbuzo 1: Ingabe i-SPD yohlobo lwesibili yanele izinhlelo eziningi zelanga?

Yebo. Ama-SPD ohlobo lwesibili amboza iningi lezingozi zokukhuphuka ezibangelwa ukufakwa okujwayelekile.

Umbuzo 2: Ngingawasebenzisa yini ama-AC SPD kumasekethe e-DC?

Cha. Ama-AC nama-DC SPD aklanywe ngendlela ehlukile futhi awakwazi ukushintshaniswa.

Umbuzo 3: Kubaluleke kangakanani ukusekela ukusebenza kwe-SPD?

Ikhwalithi yokumisa inhlabathi ithinta ngqo indlela amandla okukhuphuka akhishwa ngayo.

Umbuzo 4: Ingabe ama-SPD adinga ukulungiswa?

Kufanele zihlolwe njalo futhi zishintshwe ngemva kokubonisa ukuthi ziphelile.

Umbuzo 5: Kungani kuhlanganiswa ama-AC nama-DC SPD?

Ukuhlanganisa kunciphisa i-voltage esele futhi kuthuthukisa ukuthembeka kwesistimu.
