Umehluko phakathi kweswishi yokudlulisa okuzenzakalelayo yamandla amabili i-cb kanye ne-pc(1)

Iswishi yokudlulisa okuzenzakalelayo yamandla amabili, eyaziwa nangokuthi iswishi yokudlulisa okuzenzakalelayo, iyisici esibalulekile ohlelweni lokusabalalisa amandla. Zenzelwe ukudlulisa amandla ngaphandle kokuphazamiseka kusuka komunye umthombo kuya komunye uma kwenzeka ugesi uphela noma uhluleka. Izinhlobo ezimbili ezisetshenziswa kakhulu zokushintsha okuzenzakalelayo kwamandla amabili yi-CB (i-miniature circuit breaker) uhlobo kanye ne-PC (i-circuit breaker yekesi ebunjiwe) uhlobo. Naphezu kokufana kwazo, kukhona nomehluko omkhulu phakathi kwalezi ezimbili. Ukuze wenze isinqumo esinolwazi lapho ukhetha phakathi kokushintsha kwe-CB-class kanye ne-PC-class, kubalulekile ukuqonda izinzuzo, ukungalungi, kanye nomehluko wazo.

Okokuqala, ake sibheke ngokujulile izinzuzo zamandla amabili asezingeni le-PCukushintsha okuzenzakalelayo. Lawa maswishi abonakala ngokwakhiwa kwawo okuhlanganisiwe, okuhlanganisa indlela yokukhiya ehlangene, uhlelo lokucisha i-contact arc kanye nohlaka oluqinile. Inzuzo ebalulekile isakhiwo sawo esilula. Lokhu kusho ubukhulu obuncane, obufanele ukufakwa okunesikhala esilinganiselwe. Ngaphezu kwalokho, amaswishi ekilasi le-PC ayaziwa ngokusebenza kwawo okusheshayo kokushintsha, adinga ngaphansi kwama-millisecond angu-150 ukudlulisa amandla. Lokhu kusabela okusheshayo kuqinisekisa ukuphazamiseka okuncane kumadivayisi axhunyiwe.

Ngakolunye uhlangothi, izinkinobho ze-PC-class nazo zinezinkinga zazo. Inkinga enkulu isidingo sokuvikelwa okwengeziwe kwe-short-circuit. Lesi sidingo sandisa izindleko zokukhiqiza zenkinobho iyonke. Ngakho-ke, lesi sici kumele sicatshangelwe lapho kukhethwa i-PC-grade automatic transfer switch. Naphezu kwalokhu kusilela, izinkinobho ze-PC-class zihlala ziyisinqumo esidumile ngenxa yobukhulu bazo obuncane kanye namakhono okudlulisa amandla ngokushesha.

Amaswishi okudlulisa amandla amabili e-Class CB aqukethe ama-circuit breaker amabili anezimbobo zepulasitiki, indlela yokudlulisa ehlanganayo kanye nohlaka oluqinile. Inzuzo eyinhloko yamaswishi e-Class CB ukulayisha kwawo ukushisa okwakhelwe ngaphakathi kanye nokuvikelwa kwe-short circuit. Lokhu kuvimbela ukugeleza kwamandla kagesi okweqile kanye nomonakalo olandelayo, okuqinisekisa ukuphepha kwemishini exhunyiwe. Ngaphezu kwalokho, amaswishi e-Class CB ngokuvamile abiza kakhulu ukuwakhiqiza, okwenza kube inketho engabizi.

Kodwa-ke, izinkinobho ze-CB-class zibhekene nezinkinga ezithile. Ngokungafani nezinkinobho ze-PC-class, izinkinobho ze-CB-class zikhulu futhi zinde. Lokhu kungaletha izinselele lapho kufakwa ezindaweni eziqinile. Okunye okubi ukuthi isenzo sazo sokushintsha sihamba kancane, kuthatha imizuzwana engaphezu kwe-1.5 ukudlulisa amandla. Nakuba lokhu kubambezeleka kungase kungabi kubalulekile kwezinye izinhlelo zokusebenza, kufanelekile ukucabangela umthelela ongaba khona emishinini ebucayi.

Ngamafuphi, ukukhetha izinkinobho zokudlulisa amandla amabili ezisebenza ngokuzenzakalelayo ezingeni le-CB kanye nele-PC kuncike ezintweni eziningi. Ukuqonda izinzuzo, ububi, kanye nomehluko phakathi kwalezi zinkinobho ezimbili kungakusiza ukuthi wenze isinqumo esinolwazi. Izinkinobho ze-PC zinikeza usayizi omncane kanye nesenzo sokushintsha okusheshayo kodwa zidinga ukuvikelwa okwengeziwe kwesekethe esifushane. Izinkinobho ze-Class CB, ngakolunye uhlangothi, zinikeza ukuvikelwa kokushisa ngokweqile kanye nesekethe esifushane ngezindleko zokukhiqiza eziphansi, kodwa zikhulu futhi zinesenzo sokushintsha esihamba kancane.

Njengochwepheshe wamandla amabiliumenzi wokushintsha okuzenzakalelayo, sihlinzeka ngezinhlobo ezahlukene zezinkinobho zokudlulisa ezizenzakalelayo zezinga le-CB kanye nezinga le-PC. Imikhiqizo yethu yakhiwe ngokunemba okuphezulu ukuqinisekisa ukudluliswa kwamandla okuthembekile nokuphumelelayo. Kungakhathaliseki ukuthi udinga inkinobho encane enesenzo esisheshayo noma isisombululo esingabizi kakhulu esinesivikelo esakhelwe ngaphakathi, sinomkhiqizo ofanela izidingo zakho. Xhumana nathi namuhla ukuze uxoxe ngezidingo zakho futhi uthole inkinobho yokudlulisa ezenzakalelayo efanelekile yamandla amabili yohlelo lwakho lokusebenza.
