Ngaba Umahluko Phakathi Kwezixhobo Zokukhusela Ukunyuka Kohlobo 1 + 2 kunye Nohlobo 2?

Ukuqonda Isixhobo sokukhusela ukugquma kohlobo lwe-1+2 xa kuthelekiswa nesixhobo sokukhusela utyando sohlobo lwe-2 umahluko ubalulekile xa kuyilwa indlela esebenzayo inkqubo yokukhusela ukugaleleka kombaneIindidi ezahlukeneyo zezixhobo zokukhusela ukugqobhoza (i-SPD) zenzelwe ukujongana neemeko ezithile zokugqobhoza, ingakumbi imisinga yokuphefumla kombane kunye ne-switching transients.

Kwiziseko zophuhliso zokusasazwa kwamandla zanamhlanje, iinjineli zihlala zisebenzisa Uhlobo oludibeneyo lwe-1+2 SPD emnyango wenkonzo ukukhusela kwimisinga yombane enamandla aphezulu, ngelixa Izixhobo zokukhusela utyando lwe-Type 2 zihlala zifakelwa kwiiphaneli zokusasaza ezisezantsi.

Izakhiwo zoshishino, izakhiwo zorhwebo, kunye neenkqubo zamandla avuselelekayo zihlala zidibanisa zombini iintlobo zezixhobo njengenxalenye yenkqubo inkqubo yokukhusela ukugquma komoya ukuqinisekisa ukhuseleko oluhambelanayo kuyo yonke inethiwekhi yombane.

Imizekelo yezisombululo zokukhusela ezinamandla aphezulu inokubonwa kwi Uhlobo lwesixhobo sokukhusela ukugquma kohlobo lwe-1 + 2 isetyenziselwa ukufakwa kweenkonzo zokungena.

Ii-SDP zohlobo lwe-1 + 2 ezidibeneyo zisingatha njani umbane kunye nokunyuka kombane?

A Uhlobo oludibeneyo lwe-1+2 SPD idibanisa imisebenzi emibini yokukhusela kwisixhobo esinye:

• amandla okukhupha umbane ngokuphuma kombane (Uhlobo 1)

• umda we-overvoltage ukusuka kwi-switching surges (Uhlobo 2)

Olu dibaniso luvumela isixhobo ukuba sisebenze njenge isixhobo sokukhusela umbane ikwazi ukuqhuba ngokukhuselekileyo imisinga emikhulu yempembelelo ebangelwa kukubethwa kombane ngokuthe ngqo okanye kufutshane.

Ukhuseleko lwangoku lombane

Ngexesha lomcimbi wombane, isithinteli samandla ombane kufuneka iphathe imisinga ye-impulse echazwe luvavanyo lwe-waveform ye-10/350 μs esetyenzisiweyo kwi Isixhobo sokukhusela ukugquma kwe-IEC 61643-11 imigangatho.

Ii-SPD zohlobo lwe-1+2 zinokukhupha le misinga yamandla aphezulu ngaphandle kokonakalisa izixhobo ezisezantsi.

Ukutshintsha Ukhuseleko Lokunyuka

Ukutshintsha kwesantya kuvela kwi:

• ukutshintsha i-transformer

• Iziganeko zokuqala/zokumisa iimoto

• ukutshintsha i-capacitor bank

Ezi zixhobo zibonelela ukhuseleko lokunyuka kwebhodi yokusasazwa ephambili ngokuchasene neempembelelo zombane ezinamandla aphezulu ezingena kwinkqubo yombane.

Uhlobo lwesibini lofakelo lwe-SPD

A Isixhobo sokukhusela utyando lwe-Type 2 iqhele ukufakwa:

• kwiibhodi zokusasaza ezingaphantsi

• iiphaneli zezixhobo zangaphakathi

• kufutshane nemithwalo ye-elektroniki ebuthathaka

Ezi zixhobo zihlala zisetyenziswa njenge Izikhuseli zoxinzelelo lwesitimela se-DIN zifakelwe ngaphakathi kwiikhabhathi zolawulo okanye kwiiphaneli zokusasaza.

Ulwakhiwo oluqhelekileyo loQhagamshelwano lwe-SPD

Olu lungiselelo lwezikhundla lwenza inkqubo yokukhusela ukugquma komoya, ukuqinisekisa ukuba amandla okunyuka kwamandla ancitshiswa kancinci kancinci kuyo yonke inethiwekhi yombane.

Ungakhetha njani phakathi kohlobo 1+2 kunye nohlobo 2 lwezixhobo zokukhusela utyando?

Ukukhetha isixhobo esifanelekileyo kwi Isixhobo sokukhusela ukugquma kohlobo lwe-1+2 xa kuthelekiswa nesixhobo sokukhusela utyando sohlobo lwe-2 Uthelekiso luxhomekeke kulungiselelo lwenkqubo kunye nokuvezwa kombane.
