Cov ntaub ntawv ntawm overcurrent / overload tiv thaiv yog dab tsi?
Thaum cov zis tam sim no ntawm cov khoom siv hluav taws xob tshaj qhov ntsuas tam sim no, kev tiv thaiv Circuit Court yuav ua rau txo lossis txiav tawm lub zog tso zis.
Cov yam ntxwv ntawm overcurrent tau muab faib ua pawg hauv qab no:
Txoj kev tiv thaiv:
(1) Foldback tam sim no txwv
Thaum overloaded, cov zis tam sim no muaj peev xwm yuav txo qis, feem ntau qis dua 20 feem pua ntawm cov ntsuas tam sim no, raws li qhia hauv nkhaus a hauv daim duab.
(2) TSIS TXAUS SIAB tam sim no
Thaum overloaded, tam sim no tseem nyob rau hauv qhov kev txiav txim siab thiab cov zis voltage poob, raws li qhia hauv nkhaus b.
(3) Kev txwv lub zog
Qhov siab dua qhov tam sim no thaum lub overload yog, qhov qis voltage proportionally, raws li qhia nyob rau hauv lub nkhaus c hauv daim duab.
(4) HICCUP TXOJ CAI TSHIAB
Thaum overloaded, qhov voltage thiab tam sim no poob sai thiab txiav tawm cov zis, tab sis nws yuav cia li rov qab.
(5) TSIS TAU
Thaum overloaded, cov zis yuav raug txiav tawm, thiab cov zis voltage thiab cov zis tam sim no yuav zero.
Teb:
(1) Tom qab lub xeev overcurrent (overload) raug tso tawm, nws yuav cia li rov qab (Auto Recovery).
(2) Tom qab tso lub overcurrent (overload) lub xeev, rov pib dua (Re-Power-On).
Nco tseg: Thov zam lub sij hawm ntev overload los yog luv luv Circuit Court, uas yuav ua rau lub neej luv luv ntawm lub hwj chim mov los yog puas. Lub overload los yog luv luv-circuit tiv thaiv tsim ntawm ib co qauv yog ib tug composite hom, thiab txoj kev tiv thaiv yog xws li cov saum toj no-hais preset tam sim no txwv (los yog Foldback Current Limiting los yog Over Power Limiting) ua ntej nkag mus kaw (los yog Hiccup Current Limiting) tom qab ib lub sij hawm.
