I-1P+N, i-RCBO, i-B, i-C curve, i-ETM3RF, i-Electronic Residual Current Breaker kunye nokhuseleko lwangoku, i-din kaloliwe
Iimveliso Inkcazo
ETM3RF series RCBO ziyasebenza kwi-terminal ye-voltage ephantsi yonikezelo kushishino, isakhiwo soluntu esifana nekhaya kunye nendawo yokuhlala, amandla, unxibelelwano, iziseko zophuhliso, inkqubo yokuhambisa izibane okanye ukuhanjiswa kweemoto kunye nezinye iinkalo.Banikezela ngokhuseleko lokuvuza, ukukhuselwa kwesiphaluka esifutshane, ukukhuselwa komthwalo ongaphezulu, kunye nokukhuselwa kwedwa, okunokukhusela umntu ekulimazeni okubangelwa ukuvuza kwangoku, ngelixa benokukhusela isiphaluka kunye nezixhobo zombane kwingozi yesibini ebangelwa ukugqithisa kunye nokufutshane. isiphaluka.
ETM3RF series RCBO ihambelana ne-IEC 61009-1standard.
Umthamo wokuqhawuka we-ETM3RF yi-10KA, okanye i-6KA
Uhlobo lokukhubeka lwesekethe emfutshane ngu-B, C curve.
Ireyithingi yangoku yi-6A, 10A, 16A, 20A, 25A, 32A, 40A.Umsinga olinganisiweyo unxulumene nommandla ohlukeneyo usebenzisa umzekelo, ipali enye ye-10 ukuya kwi-16 i-ampere idla ngokusetyenziselwa ukukhanyisa, i-20 ampere ukuya kwi-33 ampere iqhele ukusetyenziselwa ikhitshi kunye nendawo yokuhlambela, isetyenziselwa ukupholisa umoya kunye nezinye izixhobo.
Uvakalelo lwangoku lweNtsalela yangoku, okanye ukukhubeka koMhlaba yi-10mA, 30mA, 100mA, ngelixa i-10mA kunye ne-30mA isetyenziswa ikakhulu kwisekethe yegumbi lokuhlambela nekhitshi ukukhusela umntu kumoyiko wombane.
Uhlobo lokukhubeka lweResidual current yi-AC okanye i-A class.Iklasi ye-AC Ukuhamba kuqinisekiswa kwi-sinusoidal, i-currents alternating, nokuba ifakwe ngokukhawuleza okanye inyuka ngokukhawuleza.Udidi lwe-Tripping luqinisekiswa kwi-sinusoidal, ukutshintshisana kwemisinga eshiyekileyo kunye ne-pulsed DC residual currents, nokuba zifakwe ngokukhawuleza okanye zinyuka ngokukhawuleza.
Umbane olinganisiweyo: 230V/240V (Isigaba & nokuPhakathi)
Kukho isalathisi sendawo esixhotyiswe kwiimveliso, Ubomvu buvuliwe, Uhlaza lucimile.
Iitheminali ze-RCBO zilukhuselo lwe-IP20 oluyilelwe ukuchukumisa umnwe kunye nesandla ngokukhuselekileyo ukugcina ukhuseleko ngexesha lofakelo.
I-ETM3RF RCBO inokusebenza ngokuthembekileyo kwimo engqongileyo erhabaxa, kwiqondo lobushushu elisuka ku-25°C ukuya kuma-55°C.
Ubomi bombane bunokufikelela kwimisebenzi ye-8000 kunye nobomi boomatshini ukuya kwi-20000 imisebenzi, ngelixa imfuno ye-IEC yimisebenzi ye-4000 kuphela kunye nemisebenzi eyi-10000.
Uhlobo lwayo lokunyuswa kufuneka lufakwe kwi-din kaloliwe EN60715 35mm.
Yintoni i-RCBO?
I-RCBO imele iResidual Current Breaker enokhuseleko lwangoku.I-RCBO idibanisa ukusebenza kwe-MCB kunye ne-RCD / RCCB.Xa kukho ukuvuza kwangoku, i-RCBO ijikeleza yonke isekethe.Ngenxa yoko, izinto zangaphakathi zemagnethi/i-thermal zesaphuli sesekethe zinokukhuba isixhobo sombane xa isekethe igcwele kakhulu.
1. Intsalela yangoku, okanye iLeakage yoMhlaba - Kwenzeka xa kukho ikhefu ngempazamo kwisekethi ngenxa yeentambo zombane ezingekho mgangathweni okanye iingozi zeDIY ezifana nokubhoboza ngentambo xa ufaka ihuku yomfanekiso okanye ukusika intambo ngomtshini wengca.Kulo mzekelo umbane kufuneka uye ndaweni ithile kwaye ukhethe eyona ndlela ilula yokuhamba ngesixhobo sokucheba ingca okanye ukomba uye kumntu obangela ukothuka kombane.
2. I-Over-current ithatha iindlela ezimbini:
a.Ukulayisha ngaphezulu - Kwenzeka xa izixhobo ezininzi zisetyenziswa kwisekethe, ukuzoba umthamo wamandla odlula umthamo wentambo.
b.Isekethe emfutshane - Iyenzeka xa kukho unxibelelwano oluthe ngqo phakathi kwabaqhubi abaphilayo kunye nabangathathi hlangothi.Ngaphandle kokuchasana okubonelelwa yimfezeko yesekethe yesiqhelo, umsinga wombane ujikeleza isekethe kwiluphu kwaye uphinda-phinda i-amperage ngamawakawaka amaxesha ngeemilliseconds nje kwaye uyingozi kakhulu kuno-Overload.
Nangona i-RCCB iyilelwe kuphela ukukhusela ekuvuzeni komhlaba kwaye i-MCB ikhusela kuphela ngokugqithisileyo, i-RCBO ikhusela kuzo zombini iindidi zesiphene.
Ukuze siqhubeke siphucula inkqubo yolawulo, ngokuhambelana nomgaqo othi "onyanisekileyo, ohloniphekileyo, umgangatho sisiseko sophuhliso lweshishini", ngokudibeneyo sithatha isiseko seemveliso ezifanelekileyo kunye nezisombululo zamazwe ngamazwe, kwaye sakha izisombululo ezitsha rhoqo ukuhlangabezana neemfuno zabathengi. .Abathengi bomgangatho ophakamileyo waseTshayina oshiyekayo oqhekezayo lwangoku, kunye nenkonzo ebalaseleyo kunye nomgangatho olungileyo, kunye neshishini lokurhweba langaphandle elibonisa impumelelo kunye nokhuphiswano, baya kuthenjwa kwaye bamkelwe ngabathengi babo kwaye bazise ulonwabo kubasebenzi.Abaqhekezi besekethe abakumgangatho ophakamileyo bafumene eyona ndumiso iphezulu kubo bonke abathengi.Inkampani yethu ibambelele kumgaqo "womthengi kuqala", kwaye izibophelele ekuncedeni abathengi bandise ishishini labo kwaye babenze abaphathi abakhulu!
Umkhuseli wokuvuza unovakalelo oluphezulu kunye nesenzo esikhawulezayo ekuphenduleni ukutshitshiswa kombane kunye nokukhuselwa kokuvuza, okungenakulinganiswa nezinye izixhobo zokukhusela ezifana ne-fuses kunye nokutshintsha okuzenzekelayo.Xa utshintsho oluzenzekelayo kunye ne-fuse ziqhelekileyo, kufuneka zigqithise umthwalo wangoku, kunye nexabiso labo lokukhusela isenzo kufuneka libekwe ukuphepha umbane oqhelekileyo wangoku, ngoko ke umsebenzi wabo oyintloko kukunqumla i-phase-to-phase-short-circuit fault of inkqubo (ezinye iiswitshi ezizenzekelayo zikwanalo nomsebenzi wokukhusela umthwalo ogqithisileyo. ).Umkhuseli wokuvuza usebenzisa intsalela yangoku yenkqubo ukusabela kunye nokwenza.Ngexesha lokusebenza okuqhelekileyo, intsalela yangoku yenkqubo iphantse ibe zero, ngoko ke ixabiso layo lokumisela isenzo linokusetwa lincinci kakhulu (ngokuqhelekileyo inqanaba le-mA).Xa isistim inomothuko wombane okanye izixhobo Xa iqokobhe lihlawuliswa, kubakho umsinga omkhulu oshiyekileyo, kwaye umkhuseli wokuvuza usebenza ngokuthembekileyo emva kokubona kunye nokucubungula umsinga oshiyekileyo ukunqumla unikezelo lwamandla.
