Yuav tsum muaj kev ntsuas tshwj xeeb rau cov dej noo uas qee zaum tshwm sim rau ntawm cov khoom vim qhov kub hloov pauv;
● Thaum txuas hluav taws xob, yuav tsum txuas tus ncej fais fab kom raug rau tus ncej zoo ntawm lub tshuab hluav taws xob, thiab tus ncej tsis zoo yuav tsum txuas rau tus ncej tsis zoo ntawm lub tshuab hluav taws xob. Tsis pub txuas rov qab;
● Qib Kev Ua Phem: Qib 2;
● Cov xwm txheej ntawm kev teeb tsa: Teeb tsa rau hauv qhov chaw uas tsis muaj kev cuam tshuam loj, kev co, thiab hauv qhov chaw nruab nrab uas tsis muaj kev phom sij (kev tawg);
● Txoj kev teeb tsa: Siv TH35-7.5 mounting rail;
●Qeb kev teeb tsa: ClassII, ClassIII.
☐ Raws li tus naj npawb ntawm cov ncej: 1P, 2P, 3P4P;
☐Raws li daim ntawv tam sim no tripping: Hom C (8ln ± 20%), Hom D (12In ± 20%);
☐ Raws li qhov ntsuas tam sim no: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A thiab 63A;
☐Raws li qhov ntsuas hluav taws xob ua haujlwm: 125V / 250V DC (1P), 250V / 500V DC (2P), 300V / 750V DC (3P), 500V / 1000V DC (4P).
● Cov yam ntxwv ntawm kev mus ncig overcurrent Thaum lub tshuab hluav taws xob raug teeb tsa raws li qhov xwm txheej ib txwm muaj thiab qhov kub thiab txias (30-35 ℃), qhov overcurrentcov yam ntxwv ntawm kev mus ncig ua raws li cov kev cai ntawm Rooj 1.
●Lub peev xwm txiav luv luv ntawm lub tshuab hluav taws xob tau qhia nyob rau hauv Rooj 2.

Lub neej hluav taws xob txhua yam:
Lub tshuab hluav taws xob Circuit Court breaker nyob rau hauv qhov ntsuas voltage teev tseg, qhib thiab tawg qhov ntsuas tam sim no, lub zog fais fab yog 0.85 ~ 0.9, kev ua haujlwm cyde 120 zaug hauv ib teev (> 32A) lossis 240 zaug (≤32A) zaus sim, nws lub neej kho tshuab thiab hluav taws xob yog 10000 zaug, lub neej hluav taws xob DC 1500 zaug.
Qauv:
Lub tshuab hluav taws xob muaj lub kaw lus sib cuag, lub kaw lus tua hluav taws xob, lub kaw lus hluav taws xob, lub tshuab tripping, lub tshuab ua haujlwm thiab lub tsev.
Txoj cai ua haujlwm:
Nyob rau hauv ib txwm ua haujlwm, rub lub tshuab ua haujlwm, lub sijhawm no tso tawmLub tshuab raug xauv, thiab cov neeg sib cuag dynamic thiab static sib cuag kom lub zog txuas nrog.
Thaum cov kab raug overloaded, daim ntawv bimetal ntawm lub electromagnetic system tsim deformation, thawb lub xauv kom tso lub mechanism, thiab txav lub contact kom disconnect thiab txiav tawm lub hwj chim. Thaum lub circuit luv luv, lub electromagnetic system rub lub hlau core, thiab lub hlau core top pas nrig thawb lub xauv kom ua rau lub mechanism tso tawm, ua tiav lub luag haujlwm tiv thaiv kev tawg ntawm lub circuit breaker.
Cov qauv qhia thiab qhov ntev ntawm kev teeb tsa ntawm lub circuit breaker tau qhia nyob rau hauv Daim Duab 1.
