3. Cov ntsiab lus tseem ceeb

3.1. Sijhawm

Kaw lub sij hawm: ncua sij hawm ntawm energizing lub kaw Circuit Court, Circuit Court breaker nyob rau hauv qhib

txoj hauj lwm, thiab qhov tam sim ntawd thaum cov neeg sib cuag kov hauv txhua tus ncej.

Lub sijhawm qhib: lub sijhawm luv ntawm lub sijhawm tam sim ntawm lub zog ntawm qhov kev tso tawm, lub Circuit Court-breaker nyob rau hauv txoj haujlwm kaw, thiab lub sijhawm tam sim ntawd thaum cov neeg sib cuag tau sib cais hauv txhua tus ncej.

Lub sij hawm bounce: Lub sij hawm sib txawv ntawm ob qho kev sib cuag kov (sib cais) thawj zaug thiab ob tus neeg sib chwv (sib cais) ruaj khov.

bounce cycles: Lub voj voog nyob rau hauv kev ua tiav ntawm lub sij hawm sib txawv ntawm ob tus neeg kov (sib cais) thawj zaug thiab ob tus neeg kov (sib cais) ruaj khov.

Lub sijhawm kaw: lub sijhawm luv ntawm lub sijhawm tam sim no thaum cov neeg sib cuag kov hauv thawj tus ncej thaum lub sijhawm ua haujlwm kaw thiab lub sijhawm tam sim thaum cov neeg sib cuag tau sib cais hauv txhua tus ncej thaum lub sijhawm qhib tom ntej.

3.2. Motion/Travel

Stroke : stroke yog qhov kev ncua deb ntawm qhov ruaj khov pib kaw (qhib) xeev mus rau qhov ruaj khov kawg kaw (qhib) xeev.

3.3. Ceev

Ceev: qhov kaw los yog qhib ceev yog txhais los ntawm tus tsim tawm Circuit Court breaker. Nws tseem hu ua tsuas yog qhib / kaw nrawm, lossis nruab nrab ceev.

Max Ceev: nws txhais tau tias qhov siab tshaj plaws nruab nrab ceev raws li qhov sib txawv ntawm 10ms.

Ceev txhais: los ntawm Circuit Court breaker producer lub ceev txhais los yog lub teb chaws tus qauv, qhov nruab nrab ceev yuav xam los ntawm lub St graph. V=△S/△t=HL/△t, HL yog qhov sib txawv, △t yog lub sijhawm sib txawv.
