Umahluko phakathi kweswitshi yokudlulisa amandla aphindwe kabini (cb) kunye ne-pc(2)

I-ATS (Utshintsho Lokudlulisa Oluzenzekelayo) licandelo elibalulekileyo kuyo nayiphi na inkqubo yamandla equka imithombo emininzi yamandla. Kwimeko yokucima kombane okanye ukuphazamiseka okunye, ivumela umbane ukuba udluliselwe ngaphandle komthungo phakathi kwale mithombo yamandla. Iindidi ezimbini ze-ATS ezisetyenziswa rhoqo ziiswitshi zokudlulisa amandla e-CB-class kunye ne-PC-class dual power automatic. Kweli nqaku, siza kuhlola iingenelo, iingxaki, kunye nomahluko phakathi kwezi ntlobo zimbini.

Kukho umahluko ocacileyo phakathi kweeswitshi zokudlulisa amandla amabini ezisebenza ngokuzenzekelayo ze-CB kunye nezo zikwinqanaba le-PC. Umahluko ophambili luxinzelelo loqhagamshelwano. Ii-circuit breakers (I-MCCB) ezisetyenziswa kwiiswitshi ze-CB-level ngokubanzi azikwazi ukumelana nomsinga wexesha elifutshane, nto leyo ebangela uxinzelelo oluphantsi loqhagamshelwano kunye nokugxothwa okanye ukutyhalwa lula. Iiswitshi ze-PC-grade, kwelinye icala, zinokumelana nemisinga engaphezulu kwe-20Ie nangaphezulu kwaye zifune uxinzelelo olukhulu loqhagamshelwano, nto leyo eyenza ukuba zingagxothwa.

Omnye umahluko kukukhetha izinto zoqhagamshelwano. Ii-CB class dual power automatic transfer switch circuit breakers zihlala zisebenzisa izinto ze-silver tungsten kunye ne-silver tungsten carbide. Ezi zinto zikhethwe ngenxa yokukwazi kwazo ukucima ii-arcs ngempumelelo. Nangona kunjalo, zichaphazeleka yi-oxidation, nto leyo enokuchaphazela ukusebenza kwazo. Ngokwahlukileyo koko, ii-PC-grade switches ziqwalasela imiphumo ye-oxidation kwaye zikhethe izinto zoqhagamshelwano ngokufanelekileyo.

Ifilosofi yoyilo olungasemva kwezi ntlobo zimbini zeswitshi nayo yahlukile. Iswitshi yokudlulisa amandla aphindwe kabini ye-CB yenziwe nge-circuit breaker kwaye inoxanduva lokuphula i-arc. Olu yilo lufuna ukuba indlela isebenze ngokukhawuleza, nto leyo enokubangela iingxaki ezifana nee-sliding buckles. Kwelinye icala, iiswitshi ze-PC-grade azijongani neengxaki ezinjalo kuba azixhomekekanga kwi-circuit breakers ngeenjongo zokuphula i-arc.

Imigama yokucima umbane kunye nokuqhekeka (umgama ofunekayo ukuze kubekho ukusebenza kombane okukhuselekileyo) nayo yahlukile phakathi kweentlobo ezimbini zeswitshi. Umgama wokucima umbane kunye nokuqhekeka kweeswitshi zokudlulisa amandla amabini ngokuzenzekelayo ze-PC-level yi-180% kunye ne-150% ngokulandelelana kweemfuno ezisemgangathweni ze-circuit breaker. Oku kwenzelwa ukuthintela iingxaki zokubeka umbane phakathi kwezixhobo zombane ezimbini ngexesha lenkqubo yokuguqula.

Ngamafutshane, iiswitshi zokudlulisa amandla amabini ezisebenzisa amandla aphindwe kabini ezikwinqanaba le-CB kunye nele-PC zinezibonelelo kunye neengxaki ezicacileyo. Iiswitshi zeClass CB zinokuba noxinzelelo oluncinci loqhagamshelwano, iimfuno zezinto ezithile zoqhagamshelwano, imiba enokubakho ye-oxidation, kunye nemingeni yoyilo enxulumene nee-circuit breakers. Iiswitshi zePC-grade, kwelinye icala, zibonelela ngoxinzelelo oluphezulu loqhagamshelwano, ukusebenza okuphuculweyo kombane ogqithisileyo, izinto eziqwalaselwayo ze-contact material oxidation, kunye noyilo olususa imfuneko ye-circuit breaker yokuphazamiseka kwe-arc. Ukukhetha phakathi kwezi ntlobo zimbini kuxhomekeke kwiimfuno ezithile zenkqubo yamandla kunye neengozi ezinokubakho ezinxulumene nohlobo ngalunye.
