Njengoba sonke sazi, c-typeI-MCBisetshenziselwa isifunda esivamile, njengesifunda sokukhanyisa;D uhloboI-circuit breakerngesekhethi yamandla emoto, ngakho-ke,C thayipha i-micro circuit breakeringasetshenziswa motor circuit?
Esikhundleni sokuthi sithi yebo noma cha, ake siqale sibheke umehluko phakathi kohlobo C no-TYPE DI-MCB:
- Ikhefu elincane lohlobo C: liqukethe ukuvikeleka kokulayishwa ngokweqile kanye nokuvikelwa kwesekethe emfushane, inani lokuhamba lokuvikela isifunda esifushane izikhathi ezingu-5~10 zamanje ezilinganiselwe;
- Ikhefu elincane lohlobo lwe-D: liqukethe ukuvikeleka kokulayishwa ngokweqile kanye nokuvikelwa kwesekethe emfushane, inani lokuhamba lokuvikela isifunda esifushane izikhathi ezingu-10~20 zamanje ezilinganiselwe;
Kokubili ukuvikelwa kokulayisha ngokweqile kuyefana, umehluko kuphela usebangeni lokuhamba lokuvikela isekethe emfushane.
Imvamisa, umthwalo ojwayelekile awunawo amandla okuqalisa, okungukuthi, umugqa wokuqala ulinganiselwe okwamanje;Isiqalo samanje se-motor cishe izikhathi ezingu-7-10 zamanje ezilinganiselwe.Nasi isibonelo:
I-4kW motor yesigaba sesithathu, ikalwe i-9A yamanje, iqala yamanje ibalwa izikhathi ezingu-10, 90A;
Ngokujwayelekile khetha i-D-type 16A micro-break njengento evikelayo, ngokuya ngezibalo zamanje zesenzo izikhathi eziyi-10, isenzo sokuvikela sesifunda esifushane singu-160A, singagwema ukuqala kwemoto yamanje;
Uma ukhetha C uhlobo 16A micro-break njengento evikelayo, ngokusho izikhathi 5 isinyathelo izibalo zamanje, ukuvikelwa short-circuit isinyathelo samanje 80A, awukwazi ukugwema motor ukuqala yamanje;Ingabe lokho kusho ukuthi ama-C breaker awayona inketho?
Akunjalo, uma ukhetha i-c-type 25A micro-break njengento evikelayo, ngokuya ngesibalo sesenzo samanje izikhathi ezi-5, isenzo sokuvikela isifunda esifushane singu-125A, singagwema ukuqala kwemoto yamanje;Kwakungekho nkinga yezobuchwepheshe.
Umnotho
Thatha wethuC63 uchungechunge MCBnjengesibonelo.I-C63 C25A ishibhile kune-C63 D16A
Ukucabanga: sivame ukukhetha isimiso se-circuit breaker ukuthi i-circuit breaker rated current inkulu kunomthwalo wamanje, ngokusho kwemvelo yohlobo lomthwalo ukukhetha C noma D uhlobo D umkhiqizi yakhelwe ngokukhethekile umthwalo umshini kagesi, kodwa akwenzi ' t kusho ukuthi i-C type breaker ayikwazi ukusebenzisa, idinga nje ukulungisa indlela yokubala, isidingo sokuhlola imvelo, ukulawula okuguquguqukayo.
