Umehluko phakathi kweswishi yokudlulisa okuzenzakalelayo yamandla amabili i-cb kanye ne-pc(2)

I-ATS (Ukushintsha Okuzenzakalelayo Kokudlulisa) iyisici esibalulekile kunoma yiluphi uhlelo lwamandla oluhlanganisa imithombo eminingi yamandla. Uma kwenzeka ugesi unqamuka noma okunye ukuphazamiseka, kuvumela amandla ukuthi adluliselwe kalula phakathi kwale mithombo yamandla. Izinhlobo ezimbili ze-ATS ezisetshenziswa kakhulu yi-CB-class kanye ne-PC-class dual power transfer automatic switches. Kulesi sihloko, sizohlola izinzuzo, ukungalungi, kanye nomehluko phakathi kwalezi zinhlobo ezimbili.

Kunomehluko ocacile phakathi kwamaswishi okudlulisa amandla amabili asebenza ngokuzenzakalelayo ezingeni le-CB kanye nalawo asezingeni le-PC. Umehluko oyinhloko ukucindezela kokuxhumana. Ama-circuit breaker (I-MCCB) ezisetshenziswa kumaswishi asezingeni le-CB ngokuvamile azikwazi ukumelana nogesi wesikhathi esifushane, okuholela ekucindezelweni okuphansi kokuxhumana kanye nokuxoshwa noma ukusunduzwa kalula. Amaswishi asezingeni le-PC, ngakolunye uhlangothi, angamelana nogesi ogcwele kakhulu ongu-20Ie nangaphezulu futhi adinga umfutho omkhulu wokuxhumana, okwenza kube lula ukuthi axoshwe.

Omunye umehluko ukukhetha izinto zokuxhumana. Ama-CB class dual power transfer automatic switch breakers ngokuvamile asebenzisa izinto ze-silver tungsten kanye ne-silver tungsten carbide. Lezi zinto zakhethwa ngenxa yekhono lazo lokucima ngempumelelo ama-arcs. Kodwa-ke, zisengozini yokushiswa yi-oxidation, okungathinta ukusebenza kwazo. Ngokuphambene nalokho, izishintshi ze-PC-grade zicabangela imiphumela yokushiswa kwe-oxidation bese zikhetha izinto zokuxhumana ngokufanele.

Ifilosofi yokuklama ngemuva kwezinhlobo ezimbili zamaswishi nayo ihlukile. Iswishi yokudlulisa amandla amabili ekilasini le-CB yakhiwe nge-circuit breaker futhi inesibopho sokuphula i-arc. Lo mklamo udinga ukuthi indlela ikwazi ukukhubeka ngokushesha, okungaholela ezinkingeni ezifana nama-buckles ashelelayo. Ngakolunye uhlangothi, amaswishi e-PC-grade awabhekene nezinkinga ezinjalo njengoba engathembeli kuma-circuit breaker ngezinjongo zokuphula i-arc.

Amabanga okusula kanye nokucwila (ibanga elidingekayo ukuze kusebenze ugesi ngokuphephile) nawo ayahluka phakathi kwezinhlobo ezimbili zamaswishi. Ibanga elijwayelekile lokusula ugesi kanye nokucwila kwamaswishi okudlulisa amandla amabili azenzakalelayo e-PC angama-180% kanye nama-150% ngokulandelana kwezidingo ezijwayelekile ze-circuit breaker. Lokhu kwenzelwa ukuvimbela izinkinga zokufaka ugesi phakathi kwemithombo kagesi emibili ngesikhathi senqubo yokuguqula.

Ngamafuphi, izinkinobho zokudlulisa amandla amabili ezisezingeni le-CB kanye nezinga le-PC zinezinzuzo kanye nokungalungi okusobala. Izinkinobho ze-Class CB zingaba nezingcindezi ezincane zokuthintana, izidingo zezinto ezithile zokuxhumana, izinkinga ezingaba khona zokuxiliswa, kanye nezinselele zokuklama ezihambisana nama-circuit breakers. Izinkinobho ze-PC-grade, ngakolunye uhlangothi, zinikeza ingcindezi ephezulu yokuthintana, ukusebenza okuthuthukisiwe kwe-overcurrent, izinto ezicatshangelwayo zokuxiliswa kwezinto zokuxhumana, kanye nomklamo osusa isidingo se-circuit breaker sokuphazamiseka kwe-arc. Ukukhetha phakathi kwalezi zinhlobo ezimbili kuncike ezidingweni ezithile zesistimu yamandla kanye nezingozi ezingaba khona ezihlobene nohlobo ngalunye.
