I-C yohlobo lwe-C miniature circuit breaker ifanelekile kwi-motor circuit?

Njengoko sonke sisazi, c-typeMCBisetyenziselwa isiphaluka esiqhelekileyo, njengesibane sokukhanyisa;D uhloboumephuli wojikelezokwisekethe yamandla emoto, ke,C uhlobo lwe-micro circuit breakeringasetyenziselwa isekethe yeemoto?

Endaweni yokuthi ewe okanye hayi, masiqale sijonge umahluko phakathi kohlobo C kunye noHLOBO DMCB:

• Uhlobo lwe-C micro break: iqulethe ukukhuselwa komthwalo ogqithisiweyo kunye nokukhuselwa kwesiphaluka esifutshane, ixabiso le-tripping yokhuseleko lwesiphaluka esifutshane ngama-5 ~ 10 amaxesha alinganisiweyo ngoku;

• I-D yohlobo lwe-micro break: iqulethe ukukhuselwa komthwalo ogqithisiweyo kunye nokukhuselwa kwesiphaluka esifutshane, ixabiso le-tripping yokukhusela isiphaluka esifutshane yi-10 ~ 20 amaxesha alinganisiweyo ngoku;

Zombini ukukhuselwa komthwalo ogqithisileyo kuyafana, umahluko kuphela ulele kuluhlu olufutshane lokhuseleko lwesekethe.

Ngokuqhelekileyo, umthwalo oqhelekileyo awunayo isiqalo sangoku, oko kukuthi, isiqalo sangoku silinganiswe ngoku;Ukuqala kwangoku kwemoto malunga namaxesha angama-7-10 okulinganiswa kwangoku.Nanku umzekelo:

I-4kW i-motor yesigaba sesithathu, ihlelwe ngoku i-9A, iqala ngoku ibalwa ngamaxesha angama-10, i-90A;
Ngokuqhelekileyo khetha i-D-uhlobo lwe-16A micro-break njengesixhobo sokukhusela, ngokutsho kwamaxesha angama-10 isenzo sangoku sokubala, isenzo sokukhusela i-short-circuit yangoku yi-160A, sinokuphepha i-motor yokuqala yangoku;

Ukuba ukhetha uC uhlobo lwe-16A micro-break njengesixhobo sokukhusela, ngokutsho kwamaxesha ama-5 isenzo sokubala ngoku, isenzo sokukhusela i-short-circuit yangoku yi-80A, ayikwazi ukuphepha i-motor yokuqala yangoku;Ngaba oko kuthetha ukuba ii-C breakers aziyiyo inketho?

Ngokuqinisekileyo akunjalo, ukuba ukhetha i-c-uhlobo lwe-25A micro-break njengesixhobo sokukhusela, ngokutsho kwamaxesha ama-5 isenzo sobalo lwangoku, isenzo sokukhusela i-short-circuit current yi-125A, sinokuphepha i-motor yokuqala yangoku;Kwakungekho ngxaki yobugcisa.

Uqoqosho

Thatha wethuC63 series MCBnjengomzekelo.C63 C25A inexabiso eliphantsi kuneC63 D16A

Ukucinga: ngokuqhelekileyo sikhetha umgaqo we-breaker circuit i-breaker circuit ireyithwe ngoku inkulu kunomthwalo wangoku, ngokohlobo lomthwalo wokukhetha i-C okanye i-D uhlobo lwe-D ngumenzi olungiselelwe ngokukodwa ukulayisha umatshini wombane, kodwa ayenzi ' t kuthetha i-C uhlobo lwe-circuit breaker ayikwazi ukusebenzisa, kufuneka nje ulungelelanise indlela yokubala, imfuno yokuphonononga indalo, ulawulo oluguquguqukayo.
