I-GBT 18487.1-2015 ichaza igama elithi umkhuseli wangoku oseleyo ngolu hlobo lulandelayo: Umkhuseli wangoku oseleyo (RCD) sisitshixo somatshini okanye indibaniselwano yezixhobo zombane ezinokutshintsha, zithwale kwaye zaphule umsinga phantsi kweemeko eziqhelekileyo zokusebenza, kunye nokuqhawula abafowunelwa xa intsalela yangoku ifikelela kwixabiso elichaziweyo.Ingumatshini wokutshintsha okanye ukudibanisa izixhobo zombane ezinokuthi zitshintshe, zithwale kwaye ziphule okwangoku phantsi kweemeko eziqhelekileyo zokusebenza kwaye zinokuphula abafowunelwa xa i-residual current ifikelela kwixabiso elichaziweyo phantsi kweemeko ezichaziweyo.
Iindidi ezahlukeneyo zomkhuseli wangoku oseleyo ziyafumaneka kwiimeko ezahlukeneyo zokukhusela kwaye uhlobo olufanelekileyo lokhuseleko lwangoku olushiyekileyo kufuneka lukhethwe kwimeko yokukhuselwa.
Ngokohlelo olusemgangathweni lwentsalela yangoku equlethe iimpawu zentshukumo yecandelo le-DC, abakhuseli bangoku abashiyekileyo bohlulwe ikakhulu kuhlobo lwe-AC olushiyekileyo lwabakhuseli bangoku, uhlobo lokhuselo lwangoku olushiyekileyo, uhlobo F olushiyekileyo lwabakhuseli bangoku kunye nohlobo B olushiyekileyo lwabakhuseli bangoku.Imisebenzi yabo ngokwahlukeneyo imi ngolu hlobo lulandelayo.
Uhlobo lwe-AC lomkhuseli wangoku oseleyo: i-sinusoidal AC eseleyo yangoku.
Uhlobo A umkhuseli wangoku oshiyekileyo: Umsebenzi wohlobo lwe-AC, ipulsating DC intsalela yangoku, ipulsating DC intsalela yangoku ebekwe ngaphezulu kwe-6mA ye-DC yangoku egudileyo.
Uhlobo F olushiyekileyo lomkhuseli wangoku: Uhlobo A, intsalela yangoku edibeneyo evela kwiisekethe eziqhutywa sisigaba kunye nokungathathi hlangothi okanye isigaba kunye nezikhondatha zomhlaba eziphakathi, i-pulsating i-DC eshiyekileyo yangoku ibekwe phezulu kumsinga we-DC ogudileyo we-10mA.
Uhlobo B olushiyekileyo lomkhuseli wangoku: Uhlobo F, i-sinusoidal AC eshiyekileyo yangoku kwi-1000Hz nangaphantsi, intsalela ye-AC yangoku ibekwe ngaphezulu kumaxesha ayi-0.4 ireyithingi yesenzo sentsalela yangoku okanye i-10mA egudileyo ye-DC yangoku (nayiphi na enkulu), ipulsating intsalela yangoku yeDC ibekwe ngaphezulu kumaxesha ayi-0.4 ireyithingiwe intshukumo yangoku okanye i-10mA egudileyo ye-DC yangoku (nokuba yeyiphi na enkulu), intsalela ye-DC evela kwiisekethe ezilungisiweyo, i-DC egudileyo.
Uyilo olusisiseko lwe-EV ebhodini lokutshaja ngokubanzi lubandakanya ukuhluza i-EMI yecandelo lokufaka, ukulungiswa kunye ne-PFC, isiphaluka sokuguqulwa kwamandla, i-EMI filter yecandelo lemveliso, njl. ulungiso lwesekethe nge transformer yodwa, apho Lg1, lg2 kunye capacitors abancedisayo zenza igalelo EMI filter, L1, C1, D1, C3, Q5 ukwenza uhlobo step-up Isigaba sangaphambili PFC circuit, Q1, Q2, Q3, Q4, T1 , i-D2, i-D3, i-D4, i-D5 yenza i-circuit yokuguqula amandla kwinqanaba elingasemva, i-Lg3, i-lg4 kunye ne-capacitors ezincedisayo zenza imveliso ye-EMI yokucoca ukunciphisa ixabiso le-ripple.
Ngexesha lokusetyenziswa kwesithuthi, ngokuqinisekileyo kuya kubakho amaqhuqhuva kunye nokungcangcazela, ukuguga kwesixhobo kunye nezinye iingxaki ezinokuthi zenze ukuba i-insulation ngaphakathi kwetshaja yemoto ibe yingxaki, ukuze itshaja yesithuthi kwinkqubo yokutshaja ye-AC kwiindawo ezahlukeneyo zohlalutyo lwendlela yokusilela. inokufumaneka ngolu hlobo lweendlela zokungaphumeleli.
(1) isiphene esisezantsi kwicala le-AC legalelo lothungelwano lukamasipala, ngelo xesha isiphene singumbane we-AC woshishino.
(2) Impazamo ephantsi kwicandelo lokulungisa, apho i-fault current is pulsating DC current.
(3) DC / DC fault emhlabeni kumacala omabini, xa impazamo yangoku igudileyo DC yangoku.
(4) impazamo emhlabeni isiguquli yedwa, impazamo yangoku non-frequency AC yangoku.
Ukusuka kuhlobo lwe-A olushiyekileyo olusebenzayo lokhuselo lwangoku lunokwaziwa, lunokukhusela umsebenzi wohlobo lwe-AC, i-pulsating ye-DC eshiyekileyo yangoku, i-pulsating i-DC eshiyekileyo yangoku iphezulu engaphantsi kwe-6mA egudileyo ye-DC yangoku, kunye netshaja ye-DC fault yangoku ≥ 6mA, uhlobo umkhuseli wangoku oseleyo unokubonakala e-hysteresis okanye akayi kwenza, okubangelwa umsebenzi oqhelekileyo, ngoko umkhuseli wangoku oseleyo uya kulahlekelwa ngumsebenzi wokukhusela.
Umgangatho waseYurophu we-IEC 61851 awugunyazisi uhlobo lwe-B, kodwa kwii-EVSE ezinezikhuseli zangoku eziseleyo zohlobo lwe-A, kuyimfuneko ukongezelela ukuqinisekisa ukuba i-fault circuit enomxholo we-DC ongaphezulu kwe-6mA inqunyulwe, enye okanye enye.Idityaniswe nohlalutyo olu ngasentla olushiyekileyo olukhethiweyo lokukhuselwa kwangoku, kuyacaca ukuba ukuba ukhuseleko lwesiphoso olungentla luza kuhlangatyezwana nalo, ukusuka kwindawo yokujonga ukhuseleko, uhlobo lwe-B oluseleyo lomkhuseli luyafuneka.
