Uhlobo lwe-CB ATS: Ukhetho olukrelekrele nolukhuselekileyo kwiiNkqubo zamandla zanamhlanje

Kwiinkqubo zamandla, iswitshi yokudlulisa ngokuzenzekelayo (i-ATS) sisixhobo esibalulekileyo esiqinisekisa ukunikezelwa kombane okuqhubekayo kwimithwalo ebalulekileyo. Phakathi kwezi, i-ATS elinganiswe yi-CB ithandwe kakhulu kwizakhiwo zorhwebo nakwizakhiwo zoshishino ngenxa yoyilo lwayo olwahlukileyo kunye neempawu zokusebenza. Eli nqaku liza kujonga iingenelo eziphambili ze-ATS elinganiswe yi-CB kwiinkalo ezintathu: ukhuseleko, ukusebenza kakuhle kweendleko, kunye nokuguquguquka kwesicelo.

I. Imisebenzi yoKhuseleko oluDibeneyo iphucula uKhuseleko lweNkqubo

(1) Ukhuseleko oluphindwe kabini kwiisekethe ezimfutshane kunye nomthwalo omninzi

I-ATS elinganiswe yi-CB ibandakanya isixhobo sokuhamba ngombane ogqithisileyo esihlala sijonga umsinga wesekethe. Ngexesha lesekethe emfutshane, oonxibelelwano abaphambili banokuphazamisa umsinga wesiphako ngaphakathi kwee-millisecond, ukuthintela ukutsha kwezixhobo okanye iingozi zomlilo. Umzekelo, kwindawo yorhwebo, i-ATS yebanga le-CB iphazamise ngempumelelo isiphako sesekethe emfutshane kwibhokisi yokusasaza, ithintela ukusasazeka komlilo. Ukhuseleko lwayo lokugqithisa, olufezekiswa zizixhobo zokuhamba ngobushushu, lubangela ngokuzenzekelayo uhambo olulibazisekileyo xa umsinga womthwalo udlula ixabiso elilinganisiweyo, ukhusela izixhobo ngelixa uphepha ukukhubeka okungeyonyani.

(2) Ukwahlulwa kweMpazamo kunye noNikezo lwaMandla oluQhubekekayo oluLingeneyo

Ngokungafaniyo ne-ATS ye-PC-grade, i-ATS ye-CB-grade yenza imisebenzi yokukhusela kunye nokudlulisa ngesixhobo esinye. Kwiimeko zombane ezihlala abantu, xa umthombo wamandla oyintloko ungaphumeleli, i-ATS ye-CB-grade ikhawuleza iqhawule isekethe enengxaki kwaye itshintshele kumthombo wamandla ogciniweyo kwimizuzwana eli-1-2. Olu yilo lususa ubunzima bokufuna ezinye iziphuli-sekethe xa usebenzisa i-ATS ye-PC-grade, nto leyo enciphisa iingozi zenkqubo ezibangelwa kukulungelelaniswa okungafanelekanga kwezixhobo zokukhusela. Umzekelo,YUYEUtshintsho lwe-CB Automatic TransferYEQ3-63W1ihlangabezana ngokupheleleyo nezi mfuno. YEQ3-63W1Iswitshi Yokudlulisa Ezenzekelayo ifanelekile kwi-AC 50Hz/60Hz, i-voltage yokusebenza elinganisiweyo yi-230V/400V kunye neesekethe zokusasazwa kwamandla kunye nolawulo ezingaphantsi. Uvavanyo lwangoku lufikelela kwi-63A. Ngokuyintloko isebenza njengeswitshi ephambili yezixhobo zombane zesiphelo kwaye inokulawula iintlobo ezahlukeneyo zeemoto, izixhobo zombane ezinamandla aphantsi, izibane, kunye nezinye izinto ezisetyenziswayo.

Ihambelana nemigangatho ye-GB/T14048.11 kunye ne-IEC947-6-1.

II. Iingenelo ezibalulekileyo zeendleko zomjikelo wobomi

(1) Iindleko zokuqala zokuthenga kunye nokulungisa ezilinganisiweyo

Nangona iiyunithi ze-ATS ezilinganiswe yi-CB zibiza ngaphantsi ngama-30%-50% ngeyunithi nganye kunezo zilinganiswe yi-PC, iindleko zazo zobomi zizonke zifuna uvavanyo olupheleleyo. Kwiprojekthi ethile yepaki yemizi-mveliso, iindleko zolondolozo zeminyaka eli-10 (kubandakanya ukulinganiswa kweyunithi yohambo kunye nokutshintshwa koqhagamshelwano) kwi-ATS ezilinganiswe yi-CB yayiyi-65% kuphela yesisombululo esilinganiswe yi-PC. Ngelixa uyilo lwayo lwesakhiwo luneendawo ezihambayo ezingaphezulu ngama-50% kuneeyunithi ezilinganiswe yi-PC, uyilo lwemodyuli lunciphisa ubunzima bokulungisa olunye, lunciphisa iindleko zomsebenzi ngama-40%. (2) Utyalo-mali oluLungileyo lokuLungiswa kweMiba yeSicelo

I-ATS yebanga le-CB ibonisa iingenelo ezibalulekileyo kwezoqoqosho kwiimeko zomthwalo ongengomthwalo ubalulekileyo njengokukhanya kwezorhwebo. Emva kokusebenzisa i-ATS yebanga le-CB, ivenkile enkulu yehlisa amazinga e-alamu yobuxoki ngama-82% ngexesha lokusetyenziswa kwamandla aphezulu ehlotyeni, ithintela ilahleko zokucima okubangelwa kukukhuselwa kokugqithiswa okungafanelekanga. Ukulungelelaniswa kwayo ngokuchanekileyo kweempawu zokukhusela kunye neeprofayili zomthwalo kunciphisa ixesha lokubuyisela utyalo-mali libe ngaphantsi kweminyaka emithathu.

III. Ukuguquguquka kwesicelo kuhlangabezana neemfuno ezahlukeneyo

(1) Ukulungelelaniswa Okuqinileyo Kwezakhiwo Zobonelelo Lombane

I-ATS elinganiswe yi-CB ingasebenza ngokuthe ngqo njengeeswitshi ze-feeder kwiinkqubo zonikezelo lwamandla e-radial ngaphandle kokufuna izixhobo zokukhusela ezongezelelweyo. Kwizakhiwo zohlobo lwe-trunk, ukulungelelaniswa okukhethiweyo kunye nee-downstream circuit breakers kwenza ukuba i-fault localization ifikelele kwinqanaba le-branch circuit. Umzekelo, emva kokusebenzisa i-CB elinganiswe yi-ATS, isityalo seekhemikhali sanciphisa izehlo zokucima komthwalo wenqanaba lesithathu ngama-70%, nto leyo eyandisa kakhulu ukuthembeka kwenkqubo.

(2) Uqinisekiso lokuThotyelwa kweMithetho yoLawulo

Ngokomgangatho omtsha we-GB51348-2019, imithwalo yokukhusela umlilo ifuna i-ATS ene-short-circuit protection kunye nemisebenzi ye-alamu yokugqithisa. I-ATS elinganiswe yi-CB ihlangabezana ngokugqibeleleyo nemfuneko "ye-alamu yokugqithisa kuphela" kwiimpompo zomlilo kunye nezixhobo ezifanayo ngokuseta iiyunithi zohambo lwe-alamu ezingakhubekiyo kuphela. Iprojekthi yesibhedlele eyamkela esi sisombululo ibone ukuphucuka kwama-50% ekusebenzeni kakuhle kokuhlolwa komlilo.

Isishwankathelo

Ngokusebenzisa uyilo oludibeneyo lokhuseleko, iindleko zomjikelo wobomi eziphuculweyo, kunye nokuguquguquka kwesicelo, i-ATS elinganiswe yi-CB ibonelela ngesisombululo sombane esingabizi kakhulu kwizakhiwo zorhwebo, kwizakhiwo zoshishino, nakwiimeko ezifanayo. Ukusebenza kwayo okulinganayo kokhuseleko kunye nokusebenza kakuhle kwezoqoqosho kwenza ukuba ibe lukhetho olukhethwayo kwiinkqubo zamandla omthwalo ongengomsebenzi ubalulekileyo. Ngophuhliso lwegridi ekrelekrele, amandla okukhusela edijithali e-ATS elinganiswe yi-CB aya kwandisa ngakumbi imida yesicelo sayo.
