Iindaba

Ukuba ulwazi lwexabiso eliphezulu iimveliso zombane kwisakhiwo, ukukwazi kwabo ukumelana nemibane lincinci kakhulu kunezixhobo zombane ezisisiseko, kuyimfuneko ukusebenzisaumkhuseli wokutyaukugcina iimveliso zombane ezichanekileyo, emva koko ungakhetha njani utyando Kuthiwani ngabakhuseli?
Ngaphambi kokukhetha iumkhuseli wokutya, qiniseka ukuba uqhuba uvavanyo lwengozi yombane kwaye uthathele ingqalelo uqoqosho lweprojekthi, kungekhona nje ilahleko echanekileyo, kodwa kunye nomonakalo ongathanga ngqo (kwinkqubo yolawulo lolwazi, umonakalo ongathanga ngqo udla ngokungaphezulu Ngaphezu koko, imithetho efanelekileyo kunye nemimiselo namhlanje zifuna ufakelo lweukutshiza abakhuseli, njengemigangatho yoshishino kazwelonke efana ne-GB 50057. Ngezantsi, ndiya kuchaza indlela yokukhetha umkhuseli wokutya kumanqanaba amaninzi.

Ukuze kuqinisekiswe ngcono ukuba iinkqubo zobonelelo lwamandla antsonkothileyo kunye neenkqubo zolwazi aziyi kwenzakala ngokubetha ngokuthe ngqo kombane kunye nokunyuka, i-IEC 62305 ichaza ngokucacileyo inkcazo yeendawo zokukhusela umbane.

I-LPZ 0A: Ukuvezwa kukubetha kombane ngokuthe ngqo, ithwele yonke imisinga yombane kunye nawo onke amasimi ombane wombane.

I-LPZ 0B: Ukukhuselwa ekubetheni kombane ngokuthe ngqo, ukumelana nombane okhoyo okanye owenziweyo ngoku, kunye nombane ogcweleyo.

I-LPZ 1: Ukukhuselwa ekubetheni ngokuthe ngqo kombane, imisinga yombane yasekhaya okanye imisinga ebangelwayo, kunye nombane othotyiweyo wemagnethi.Utyando luthintelwe ekuvalelekeni kumda kwaye ukhuselwe ngumkhuseli wokutyanda, kwaye indawo ye-electromagnetic ikhusele ukuthomalaliswa kwendawo.

I-LPZ 2…n: Ifana ne-LPZ 1, kodwa ngokucutha ngakumbi indawo yombane wokubetha kombane.Njengomthetho wokukhusela jikelele, into ekhuselweyo kufuneka ibekwe kwindawo ye-LPZ eneempawu ze-electromagnetic ezihambelana nokukwazi ukumelana nomonakalo wokunciphisa umonakalo (umonakalo womzimba, ukungaphumeleli kweenkqubo zombane kunye ne-elektroniki ngenxa yokugqithisa, njl.

Indlela yokukhetha ehambelanayoumkhuseli wokutya

Xa kungenakwenzeka ukulinganisa iklasi 1 umkhuseli wokunyuka (Uhlobo1, iClass1), Iimp≥12.5kA isetyenziswa ngokuqhelekileyo, oko kukuthi, i-12.5kA yanele kwiimeko ezininzi.Sincoma ukusebenzisa ii-Iimp=25kA, ukwenzela ukuba kuya kubakho Umthamo omkhulu, ubomi benkonzo obude.

Kudidi lwesi-2 lwabakhuseli botyando (Uhlobo 2, iKlasi2), sikhetha ukusebenzisa i-20/40kA (In=20kA, Imax=40kA) izikhuseli zokunyuka kwamandla, kunye nokubetha kombane ngaphezu kwe-40kA (emva kwe-LPZ1) kunqabile ukuba ziveliswe kwizicelo ezithile.ye.Kukho iintlobo ezininzi zoKhuseleko lwe-2 lokutyanda, kubandakanywa i-40/80kA, 50/100kA, kunye ne-60/120kA yokukhusela amandla ombane.

Ukuhlangabezana neemfuno zokhuseleko kumazwe amathathu asebenzayo

1. Imo yokulinda: iimpawu zokuguga kwamandla ombane, ukufuma kunye neempawu zokuxhathisa ubushushu, ukuthwala ngokukhuselekileyo komkhuseli wokutyanda kabini;

2. Imeko yokucinezelwa kwe-Surge: Ukongeza kumandla ombane osebenzayo wenkqubo, umkhuseli wokutya ukwanawo amandla asuka kumbane wokusurgery;

3. Imeko yokusebenza ye-TOV: Uxinzelelo lombane lweumkhuseli wokutyaubukhulu becala yi-TOV yombane osebenzayo kunye neyangoku.Oku kunxulumene nomgangatho wegridi, unikezelo lwamandla ombane ophantsi kunye neenkqubo zokusasazwa kwamandla ombane, iinkqubo zokusasazwa kwamandla ombane aphakathi kunye neendlela zokubeka phantsi kweenguqu zokuhambisa umbane.Eyona nto ifunwayo kukukwazi komkhuseli wokutyanda ukumelana nokugqithisa okwexeshana, oko kukuthi, umkhuseli wokutyanda unokumelana ne-UT echazwe kumgangatho.

Isiqinisekiso esigunyazisiweyo ekhaya nakwamanye amazwe

Ekugqibeleni, kukwabalulekile ukukhetha iimveliso ezinesatifikethi esigunyazisiweyo somntu wesithathu (njenge-CE, TUV, CAS, CQC, njl.), kunye nokukhetha iinkampani ezinokuqokelela kobugcisa, izibonelelo zobugcisa, kunye nezisombululo ezivakalayo.

Ngokutsho kwe-TUV, i-CE, i-CQC kunye nezinye iziqinisekiso zamazwe ngamazwe, umkhuseli wokuqhafaza unobuchwephesha obubalaseleyo bokuvelisa kunye nokucubungula iteknoloji kwintsimi yokukhusela umbane, kwaye unokuhlangabezana neemfuno zesicelo phantsi kweemeko ezinzima ezifana nobushushu obuphezulu, ubushushu obuphezulu kunye neendawo zethafa, kwaye inokumelana ne-harmonic current kunye ne-overvoltage ixesha elide.,Surge abakhuseliingenziwa ngokwezifiso kubathengi kwiindawo ezizodwa.
