Umahluko phakathi kweswitshi yokudlulisa amandla aphindwe kabini (cb) kunye ne-pc(1)

Utshintsho lokudlulisela oluzenzekelayo lwamandla amabini, eyaziwa ngokuba yi-automated transfer switch, yinxalenye ebalulekileyo kwinkqubo yokusasazwa kwamandla. Zenzelwe ukuhambisa amandla ngaphandle komthungo ukusuka kwenye indawo ukuya kwenye xa umbane ucimile okanye ungaphumeleli. Iindidi ezimbini ezisetyenziswa kakhulu ze-dual power automatic transfer switches yi-CB (iqhekeza lesekethe elincinciuhlobo kunye nePC (iqhekeza lesekethe elibunjiweyo) uhlobo. Nangona zifana, kukwakho umahluko omkhulu phakathi kwezi zimbini. Ukuze wenze isigqibo esinolwazi xa ukhetha phakathi kokutshintsha kwe-CB-class kunye ne-PC-class, kubalulekile ukuqonda izibonelelo, iingxaki kunye nomahluko wazo.

Okokuqala, makhe sijonge nzulu iingenelo zamandla amabini akwinqanaba lePCiiswitshi zokutshintsha ezizenzekelayoEzi switshi zibonakaliswa lulwakhiwo lwazo oludibeneyo, kubandakanya indlela yokudibanisa, inkqubo yokucima i-contact arc kunye nesakhelo esomeleleyo. Inzuzo ebalulekileyo kukwakheka kwayo okulula. Oku kuthetha ubungakanani obuncinci, obufanelekileyo kwiindawo ezifakelweyo ezinesithuba esincinci. Ukongeza, iiswitshi zeklasi ye-PC zaziwa ngokusebenza kwazo ngokukhawuleza kokutshintsha, ezifuna ngaphantsi kwe-150 milliseconds ukuhambisa amandla. Le mpendulo ikhawulezayo iqinisekisa ukuphazamiseka okuncinci kwizixhobo ezixhunyiweyo.

Kwelinye icala, iiswitshi zeklasi ye-PC nazo zineengxaki zazo. Ingxaki enkulu kukufuneka kokhuseleko olongezelelweyo lwe-short-circuit. Le mfuneko yonyusa iindleko zokwenziwa kweswitshi iyonke. Ke ngoko, le nkalo kufuneka iqwalaselwe xa kukhethwa iswitshi yokudlulisa ngokuzenzekelayo ye-PC-grade. Nangona le ngxaki ingekho, iiswitshi zeklasi ye-PC zihlala zilukhetho oludumileyo ngenxa yobukhulu bazo obuncinci kunye nokukwazi kwazo ukudlulisa amandla ngokukhawuleza.

Iiswitshi zokudlulisa ezizenzekelayo zeClass CB ezisebenzisa amandla amabini ziquka ii-circuit breakers ezimbini zeplastiki ezineebhokisi, indlela yokudlulisa edibeneyo kunye nesakhelo esiqinileyo. Inzuzo ephambili yeeswitshi zeClass CB kukugqithiswa kobushushu okwakhelwe ngaphakathi kunye nokukhuselwa kwesekethe emfutshane. Oku kuthintela ukuhamba kwamanzi amaninzi kunye nomonakalo olandelayo, kuqinisekisa ukhuseleko lwezixhobo ezixhunyiweyo. Ukongeza, iiswitshi zeClass CB zihlala zibiza kakhulu ukuzenza, nto leyo eyenza zibe lukhetho olufikelelekayo.

Nangona kunjalo, iiswitshi zeklasi ye-CB zijongene neengxaki ezithile. Ngokungafaniyo neeswitshi zeklasi ye-PC, iiswitshi zeklasi ye-CB zikhulu kwaye zinde. Oku kunokubangela imingeni xa kufakwa kwiindawo ezixineneyo. Enye ingxaki kukuba isenzo sazo sokutshintsha sicotha, sithatha ngaphezu kwemizuzwana eyi-1.5 ukuhambisa umbane. Nangona oku kulibaziseka kusenokungabalulekanga kwezinye iinkqubo, kufanelekile ukuqwalasela impembelelo enokubakho kwizixhobo ezinobuthathaka.

Ngamafutshane, ukukhetha iiswitshi zokudlulisa amandla ezimbini ezisebenza ngokuzenzekelayo ze-CB kunye ne-PC kuxhomekeke kwizinto ezininzi. Ukuqonda iingenelo, iingxaki, kunye nomahluko phakathi kwezi zimbini kunokukunceda wenze isigqibo esinolwazi. Iiswitshi zeklasi ye-PC zibonelela ngobukhulu obuncinci kunye nesenzo sokutshintsha ngokukhawuleza kodwa zifuna ukhuseleko olongezelelweyo lwesekethe emfutshane. Iiswitshi zeklasi ye-CB, kwelinye icala, zibonelela ngoxinzelelo lobushushu kunye nokhuseleko lwesekethe emfutshane ngeendleko eziphantsi zokuvelisa, kodwa zikhulu kwaye zinesenzo sokutshintsha esicothayo.

Njengomntu oqeqeshiweyo onamandla amabiniumenzi weswitshi yokudlulisa ngokuzenzekelayo, sinikezela ngeendidi ngeendidi zeeswitshi zokudlulisa ezizenzekelayo zenqanaba le-CB kunye nele-PC. Iimveliso zethu zenziwe ngokuchanekileyo ukuqinisekisa ukudluliselwa kwamandla okuthembekileyo nokusebenzayo. Nokuba ufuna iswitshi encinci enesenzo esikhawulezayo okanye isisombululo esingabizi kakhulu esinokhuseleko olwakhelwe ngaphakathi, sinemveliso ehambelana neemfuno zakho. Nxibelelana nathi namhlanje ukuze uxoxe ngeemfuno zakho kwaye ufumane iswitshi yokudlulisa ezenzekelayo egqibeleleyo yamandla amabini kwisicelo sakho.
