Imfuneko yezixhobo zokhuseleko zombane ezikumgangatho ophezulu mkhulu kunangaphambili.Amacandelo amashishini kunye nezorhwebo afuna ubuchule obuninzi ukuze kuqinisekiswe iigridi ezizinzileyo, unikezelo lwamandla olukhuselekileyo kunye nokukhusela iimpahla zabo.Ukuveliswa kweabaqhekezi besekethe abakrelekrele abakrelekrelekunye nokusebenza kwabo okuthembekileyo kuye kwaba yinguqu yomdlalo kwishishini.Namhlanje, siza kujonga ngakumbi indlelai-air circuit breaker (ACB)sisiseko sayo nayiphi na inkqubo yanamhlanje yokuhanjiswa kwamandla.
IIntelligent Universal Circuit Breaker, esiyibizayoI-ACB, sisixhobo sokukhusela esitsha esiqinisekisa igridi ezinzileyo ngokusebenzisa imisebenzi ehlakaniphile.Iqulathe izinto ezininzi ezibandakanya iiyunithi zohambo, abenzi boluvo kunye nee actuators.Abaphuli beesekethe banoxanduva lokukhubeka xa kukho imeko engaqhelekanga kwigridi, njengomthwalo ogqithisiweyo, isiphaluka esifutshane okanye impazamo yomhlaba, kunye nokuhlukanisa ngokupheleleyo isiphaluka.Xa sikhubekile, isixhobo silumkisa umsebenzisi wenkqubo nge-alam okanye ngomqondiso.
I-ACB isebenza ngokugqithiseleyo ngenxa yokuba inokunxibelelana namacandelo ahlukeneyo ombane, kubandakanywa nezinye ii-circuit breakers, iimitha, kunye nokuhanjiswa, ukuvumela ukubeka iliso ngokupheleleyo kwigridi.Obu bulumko bungundoqo ekuphuculeni ukhuseleko, ukusebenza kunye nenzuzo yofakelo lombane.Ngokuqokelela kunye nokucubungula idatha malunga namandla, amandla kunye neeparitha ezininzi, abaphuli beesekethe bancedisa ukukhusela izixhobo, ukukhusela iintlekele kunye nokwandisa ukusebenza kakuhle.
Ii-ACB zifumaneka kwiindidi ezahlukeneyo zobukhulu kunye neentlobo, ezisenza sikwazi ukuhlangabezana neemfuno ezahlukeneyo zesicelo kwishishini.Ulwakhiwo lwesixhobo lubandakanya i-body breaker yesiphaluka exhotywe ngoqhagamshelwano lombane, indlela yokusebenza kunye nokukhululwa.Ukwakhiwa koqhagamshelwano lwayo lubhedu olune-laminated kunye nokubunjwa kwe-multi-layer kunye nokunyamezela okuchanekileyo kuqinisekisa umgangatho ophezulu wokuqhuba umbane kunye nokuqina.Indlela yokusebenza kwayo ingaba ngumbane okanye intwasahlobo, okusivumela ukuba sifake ama-breaker circuits ngokuthembekileyo, ngokufanelekileyo nangokulula kwiimeko ezinzima.
Okokugqibela, iyunithi yohambo yeyona ngqondo ibalulekileyo ye-ACB njengoko ihlalutya i-waveform kwaye imisela ixesha lokuhamba.Iiyunithi zohambo zinokuba yi-elektroniki okanye i-electromechanical, kuxhomekeke kwisicelo.Iquka i-CT, i-PT, ibhodi yesiphaluka yokulawula kunye ne-microprocessor.I-CT kunye ne-PT isampula yangoku kunye ne-voltage ngokulandelanayo, kwaye ithumele isignali kwibhodi yokulawula ukuze iqhutywe.I-microprocessor emva koko ihlalutya idatha yesignali ukufumanisa ukuba kukho ukungahambi kakuhle kwisekethe kwaye, ukuba kuyimfuneko, ikhupha umyalelo wohambo kwi-actuator, ngaloo ndlela ikhubeka indlela.
Ukushwankathela, iokrelekrele universal circuit breakersisixhobo esibalulekileyo sokukhusela umbane ukuqonda inkqubela enkulu yegridi yamandla yelizwe lam.Ngeempawu zayo ezikrelekrele nezithembekileyo kunye nemisebenzi, abaphuli beesekethe baphucula kwaye baqinisekise ukhuseleko, ukusebenza kunye nokusebenza kakuhle kofakelo lombane.Njengoko ishishini liqhubeka likhula kwaye likhula, ukubaluleka kokhuseleko lombane akunakugxininiswa.I-ACB ibonelela ngezisombululo zonke ezihlangabezana neemfuno ezahlukeneyo zezicelo kunye nokuqinisekisa ukuqhubeka kokunikezelwa kwamandla, ngaloo ndlela ukwandisa ukuthembeka kunye nemveliso kumacandelo oshishino kunye nezorhwebo.
