Idivayisi Yokuvikela Ukukhuphuka Kohlobo 1+2 vs Uhlobo 2 Kuphela: Yisiphi i-SPD Ekufanele?

Ngiyazi ukuthi kungaba nzima kangakanani ukukhetha idivayisi efanele yokuvikela ukukhuphuka kwamandla uma yonke iphrojekthi incike emandleni azinzile naphephile.

I-Type 1+2 SPD inikeza kokubili ukuvikelwa okunamandla kombani kanye nokulawula okuthembekile kokushintshana komoya, kuyilapho i-Type 2-kuphela SPD igxile kakhulu ekukhuphukeni kwangaphakathi kanye nokubangelwa. Ukukhetha okungcono kuncike ezimweni zakho zegridi, ukwakheka kwesakhiwo, kanye nezinga lengozi.

Ngifuna ukukuqondisa isinyathelo ngesinyathelo ukuze ukwazi ukuqhathanisa zombili izinketho ngokucacile futhi wenze ukukhetha okuqinisekile kwesikhungo sakho.

Impendulo Esheshayo: Isinqumo Sakho Esiyinhloko Sokuvikela Ukwanda

Ngiyayiqonda ingcindezi lapho udinga impendulo ecacile ngokushesha, ikakhulukazi uma isikhathi sephrojekthi sincane.

Kufanele ukhethe i-Type 1+2 SPD uma indawo yakho ingase ibhekane nokukhanya okukhulu noma igridi engazinzile. Kufanele ukhethe i-Type 2-only SPD uma isakhiwo sakho sisendaweni evikelwe futhi ikakhulukazi sibhekene nokushintshashintsha okukhulu. Ukukhetha okulungile kuncike endaweni yokufaka, isilinganiso se-short-circuit, kanye nemithetho yokuphepha okumele uyilandele.

Iyunithi yohlobo 1+2 ikunikeza idivayisi eyodwa ephatha izingozi ezimbili ezinkulu. Isebenza kahle ezitshalweni zezimboni, ezakhiweni zezentengiselwano, nasezindaweni ezinezintambo zangaphandle. Iyunithi yohlobo 2 kuphela ivame kakhulu kumaphaneli okusabalalisa angaphakathi lapho umbani ungeyona inkinga. Ngifuna ukukusiza uqhathanise zombili izinketho ngendlela elula neqondile ukuze ugweme amaphutha ekukhetheni kwakho.

Iyini Idivayisi Yokuvikela Ukwanda?

Ngikhumbula ngikhuluma neklayenti elalikhathazekile ngokuthi ukukhuphuka okukodwa kungawuvala wonke umugqa walo, futhi lalidinga impendulo elula elingayethemba.

Idivayisi yokuvikela ukukhuphuka ithumela i-voltage eyengeziwe emhlabathini ngokuphephile ngaphambi kokuba ifike emishinini yakho. Yehlisa umthelela wombani, ukukhuphuka kokushintsha, kanye nokukhuphuka kwegridi ngokugcina i-voltage isezingeni eliphephile.

Lokho okwenziwa yi-SPD

I-SPD isabela ngokushesha kakhulu ekukhuphukeni kwamandla kagesi okungazelelwe. Isebenza njengevalvu yokucindezela kagesi. Lapho amandla kagesi ekhuphuka ngaphezu kwendawo ephephile, i-SPD ivula indlela eya phansi. Lapho amandla kagesi ebuyela esimweni esijwayelekile, i-SPD iyavalwa futhi. Ukwanda kwamandla kagesi kuvela kugridi, kusuka embaneni, kanye nasemishinini engaphakathi kwesakhiwo sakho. Amafektri amaningi abhekana nalezi zinkinga nsuku zonke ngoba izinjini ziyaqala, ama-drive ayashintsha, futhi imithwalo iyashintsha.

Izinhlobo Zokukhuphuka

Ngezansi ithebula elilula lokubonisa imithombo eyinhloko yokwanda kwezakhi zofuzo nokuthi zivame ukubangelwa yini:

Kungani ama-SPD ebalulekile kubaphathi bokuthenga

I-SPD enhle yehlisa isikhathi sokungasebenzi futhi ivikela imishini ebucayi. Futhi iyingxenye ebalulekile yokunciphisa izindleko eziphelele zobunikazi ngoba ivimbela ukwehluleka okubiza kakhulu kune-SPD. Uma umhlinzeki eqonda izinkinga zakho zegridi, angafanisa i-SPD nengozi ukuze ugweme ukwehluleka okuvamile kwensimu. Izimboni eziningi zisebenzisa amayunithi abuthakathaka kakhulu kunezimo zawo zangempela, futhi lokhu kuholela ekuwohlokeni okubambezela ukukhiqizwa. Inqubo yokukhetha ecacile iyasiza ekumiseni le nkinga futhi igcine umugqa wakho uzinzile.

Uhlobo 1: Ukuphathwa Kokukhuphuka Okuphezulu Komfutho (Iimp)

Ngikhumbula ukuvalwa kwefektri okwathatha isigamu sosuku ngoba umbani oqondile washaya umnyango wesevisi washisa iphaneli eyinhloko. Akekho ofuna lolo hlobo lokungasebenzi.

I-Type 1 SPD ivikela ekukhuphukeni kombani okunamandla aphezulu. Ifakwa emnyango wesevisi futhi iphatha ama-waveform e-Iimp ukuze ugesi omkhulu uphambukiswe ngaphambi kokuba ungene esakhiweni.

Kungani Kukhona Ama-SPD Ohlobo 1

Ukukhanya kombani kungafinyelela imisinga ephezulu kakhulu. Kungase kube yinto engavamile, kodwa isenzakalo esisodwa singabhubhisa i-switchboard eyinhloko ngokushesha. Ama-SPD ohlobo 1 asebenzisa izikhala ze-spark noma izinhlelo ze-MOV eziqinisiwe ezakhelwe ukukhanyisa okuphezulu. Inhloso yawo ilula: ukumisa ukukhanya endaweni yokungena ukuze igiya elingezansi lingagcwali ngokweqile.

Imininingwane Ebalulekile Okufanele Uyazi

Nazi izici eziyinhloko:

Lapho Uhlobo 1 Lusetshenziswa khona

Ngokuvamile ubona ama-SPD ohlobo 1 ezindaweni ezinengozi ephezulu yombani noma ingqalasizinda eveziwe:

1. Izakhiwo ezinezivikelo zangaphandle zombani

2. Izindawo zezimboni ezinzima

3. Iziteshi ezikude noma ezingenabantu

4. Imibhoshongo yeTelecom

I-Type 1 SPD isusa iningi lamandla okukhuphuka ngaphambi kokuba ifike ebhodini lokusabalalisa. Njengoba amandla amancane ehamba phansi komfula, amadivayisi afana nama-drive, ama-PLC, izinsiza zikagesi, kanye nezinzwa abhekana nokwehluleka okuncane kakhulu. Uma igridi ingazinzile, lolu ngqimba lokuqala lokuvikela luvimbela ukuvalwa okungahleliwe kanye nezindleko zokulungisa ezingalindelekile.

Uma umbani uyingxenye yephrofayili yakho yengozi, i-Type 1 SPD ayiyona into ongayikhetha—iyisivikelo sakho sokuqala emgqeni wokuzivikela.

Uhlobo 2: Ukushintsha Nokugqugquzelwa Kokukhuphuka Okubangelwayo

Lapho ikhasimende lingitshela ukuthi imishini yalo yehlulekile ngisho nangezinsuku ezicacile nezingenaziphepho, kwakusobala ukuthi libhekene nokushintshashintsha kwangaphakathi—hhayi umbani nhlobo.

I-SPD yohlobo lwesibili ivikela ekushintsheni nasekukhuphukeni okubangelwayo okukhiqizwa ngaphakathi kwesikhungo. Ivimba ama-spikes anamandla aphakathi abangelwa ama-motor, ama-drive, ama-capacitor banks, kanye nokusebenza kwegridi okuvamile. Lawa ma-SPD afakwa kumaphaneli okusabalalisa ukuze avikele imithwalo engezansi.

Yiziphi izinhlobo ze-SPD zohlobo lwesibili ezenzayo

Ama-SPD ohlobo lwesibili alawula ukwanda okwenzeka ngokuphindaphindiwe nsuku zonke. Iningi lala ma-spikes livela ngaphakathi kwesitshalo uqobo. I-startup yemoto idala ukwehla kwamandla kagesi okubukhali kanye nokubuyela emuva, ukushintshana kwe-capacitor kubangela ukuhamba okusheshayo, kanti ama-VFD aletha umsindo kagesi. I-SPD yohlobo lwesibili ibamba lezi zenzakalo ngaphambi kokuba zifinyelele kuma-elekthronikhi abucayi.

Izicelo Ezivamile

Ngaphambi kokuba sibheke izindawo ezijwayelekile, nansi ithebula elifushane elifingqa lapho ama-SPD ohlobo lwesibili enikeza khona inani elikhulu:

Kungani Amasayithi Amaningi Esebenzisa Uhlobo 2 Kuphela

Izakhiwo ezitholakala ezindaweni ezivikelwe—njengezakhiwo ezingenazo izibani zangaphandle, amaphaneli angaphakathi kuphela, noma amapaki amakhulu ezimboni—azivami ukubhekana nokukhanya okuqondile kombani. Okukhathazayo kakhulu umsebenzi wokushintshashintsha oqhubekayo owenzeka ngaphakathi.

I-SPD yohlobo lwesibili kuphela ishibhile, ithembekile, futhi ifaneleka kahle ekufakweni kwezakhiwo okujwayelekile. Kumasethingi amaningi ezimboni zezentengiselwano noma zangaphakathi, inikeza konke ukuvikelwa okudingekayo.

Amaphuzu Okukhetha

I-SPD yohlobo lwesibili ethembekile kufanele inikeze:

1. Isilinganiso esiphezulu sokukhuthazela okuphindaphindiwe kokunyuka

2.Inani eliphansi eliphezulu lokuvikela ama-elekthronikhi abucayi

3. Ama-MOV aqinile, avikelwe ukushisa

4. Amamojula we-plug-in angashintshwa ukuze kube lula ukugcinwa

Ukukhetha i-Type 2 SPD eqinile neklanywe kahle kusiza ukuqinisekisa ukuthi imishini yakho ihlala izinzile ngaphansi kokucindezeleka kokushintsha kwansuku zonke.

Uhlobo 1+2 Idivayisi Yokuvikela Ukwanda: Isixazululo Esihlanganisiwe

Abathengi abaningi bangitshela ukuthi bafuna idivayisi eyodwa engakwazi ukusingatha yonke into—ukwanda kombani, ukushintshashintsha kwama-spikes, kanye nezimo zegridi ezingalindelekile. Yingakho nje kukhona ama-SPD ohlobo 1+2.

I-Type 1+2 SPD ihlanganisa ukuvikelwa kombani okunamandla aphezulu kohlobo 1 kanye nekhono lokubopha i-switching-surge lohlobo 2. Ifakwe ebhodini lokusabalalisa eliyinhloko, inikeza ikhambi ledivayisi eyodwa kokubili imisinga ye-impulse kanye nemicimbi yesikhashana yansuku zonke.

Kungani Abathengi Abaningi Bekhetha Uhlobo 1+2

Uhlelo lukagesi lwesimanje lubhekene nenhlanganisela ebanzi yezinhlobo zokuqhuma. Umbani ungashaya iziphakeli zangaphandle, kuyilapho ama-motor, ama-drive, kanye nokushintsha kwegridi kukhiqiza ama-spikes angaphakathi avamile. Esikhundleni sokufaka ama-SPD amabili ahlukene, iyunithi yohlobo 1+2 iphatha zombili izimo ngasikhathi sinye.

Lokhu kuyenza ibe yisivikelo esithembekile sezindawo ezingakwazi ukukhokhela isikhathi sokuphumula noma ukuxazulula izinkinga.

Izinzuzo

Ngaphambi kokuthi sihlole izindawo ezijwayelekile, nansi ithebula elifingqa amazinga amabili okuvikela alethwa yi-Type 1+2 SPD:

Uma Uhlobo 1+2 Lunengqondo

I-Type 1+2 SPD iwusizo kakhulu uma:

1. Izimo zokwanda azicaci noma ziyaguquguquka

2. Igridi ayizinzile noma imishini isebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto

3. Isakhiwo sichayeke kokubili emithonjeni yokwanda kwamanzi yangaphandle neyangaphakathi

4. Abaklami bakhetha ungqimba olulodwa oluvikelayo kuphaneli eyinhloko

5. Ukuthobela imithetho yokuvikela ukukhuphuka kwezwe okulula kuyadingeka

Ezindaweni ezinezingozi ezixubile, lesi sixazululo esihlanganisiwe sikunikeza ukuqina okuqinile kanye ne-voltage ehlanzekile engezansi.

 Izinzuzo ze-Type 1+2 SPDs

I-Type 1+2 SPD eklanywe kahle inikeza:

1. Ukuvikela kokubili umbani kanye nokushintshashintsha kwamandla

2. Ubunzima bokufaka obuphansi uma kuqhathaniswa namadivayisi ahlukene

3.Ukuthembeka okungcono kwesikhathi eside kwezinhlelo zokwenza izinto ngokuzenzakalela ezibucayi

4. Ukulungiswa kwesistimu okulula kuwo wonke amaphaneli namasayithi amaningi

Ezikhungweni ezifuna ukuphepha okulinganiselayo, ukuguquguquka, kanye nobulula, Uhlobo 1+2 luvame ukuba yisinqumo esihlakaniphile kakhulu sesikhathi eside.

Izici Zezinqumo Nezincomo Zecala Lokusetshenziswa

Ukukhetha phakathi kwe-Type 1+2 SPD kanye nemodeli yohlobo 2 kuphela kuvame ukuncika ekulinganiseni ukuvikelwa, izindleko, kanye namaqiniso endawo yakho kagesi. Abaphathi abaningi bokuthenga bangitshela ukuthi bafuna ukucaca—into ewusizo abangayisebenzisa ngaphandle kokuqagela.

Kufanele usebenzise i-Type 1+2 SPD uma udinga isivikelo esiphelele ebhodini lokusabalalisa eliyinhloko, okuhlanganisa kokubili ukushukuma kombani kanye nokukhuphuka kokushintsha. I-Type 2-only SPD ifaneleka kumaphaneli esibili lapho kulindeleke khona umsebenzi wokuqhuma kwangaphakathi kuphela. Ukukhetha kwakho kokugcina kufanele kubonise ukuchayeka kwegridi, indawo yokufaka, amazinga endawo, kanye nokubaluleka kwemishini.

Amaphuzu Esinqumo Esiyinhloko

Ukuze sikusize uqhathanise lezi zixazululo ezimbili ngokucacile, nansi ithebula elifushane elifingqa izindlela eziyinhloko zokuthatha izinqumo:

Izincomo Eziwusizo

Uma isakhiwo sakho sisesifundeni esineziphepho ezivame ukwenzeka—noma uma umugqa wokungenisa izinto ongenayo uvezwa ngaphandle—khona-ke i-Type 1+2 SPD iyindlela ephephile futhi evame ukudingeka. Izindinganiso eziningi zigunyaza ukuvikelwa kwezinga lombani esangweni lesevisi ezindaweni ezinjalo.

Ezindaweni ezitholakala ezindaweni ezivikelwe noma ngaphakathi kwezakhiwo ezinkulu zezimboni, ukushintshashintsha kwamandla kuvame ukuba yinkinga enkulu. Kulezi zimo, i-SPD yohlobo lwesibili kuphela inikeza isivikelo esithembekile nesingabizi kakhulu semisebenzi yansuku zonke.

 Indlela Yokukhetha Ngokuzethemba

Uma usebenzisa izinhlelo ezibalulekile zomsebenzi, imishini yokuzenzakalela, noma imigqa yokukhiqiza engu-24/7, i-Type 1+2 SPD inikeza ukuzinza okukhulu kanye nokuthembeka kwesikhathi eside. Uma okubaluleke kakhulu kuwe kuwukuvimbela umonakalo ovela ezenzakalweni zokushintsha kwangaphakathi, khona-ke i-Type 2-kuphela SPD ivame ukwanele.

Uma ungabaza, amaphrojekthi amaningi amasha akhetha Uhlobo 1+2 ukuze lumbozwe kabanzi kanye nokulawula izingozi zesikhathi eside okulula.

Isiphetho

Khetha i-SPD efanelana nengozi yakho yangempela yokukhuphuka. Uma ungabaza, sebenzisa Uhlobo 1+2 ukuze uthole isivikelo esiqinile. Xhumana nawe uma ufuna isiqondiso esicacile sephrojekthi yakho elandelayo.
