Miniature Circuit Breaker Accessories Txhim Kho Kev Nyab Xeeb thiab Kev Ua Haujlwm
Cov Chaw Pabcuam Tiv Thaiv (OF) ua haujlwm tseem ceeb ntawm cov xwm txheej tseem ceeb thiab cov neeg tswj xyuas. Mechanically txuas rau lub MCB's kev khiav hauj lwm mechanism, lawv muab ib tug txhim khu kev qha hluav taws xob teeb liab qhia txog lub breaker lub xeev qhib (OFF) los yog kaw (ON). Cov ntaub ntawv no yog qhov tseem ceeb rau cov chaw taws teeb saib xyuas, SCADA systems, lossis kev sib cuam tshuam circuits, tso cai rau cov tswv lag luam kom paub meej txog qhov xwm txheej tsis muaj kev tshuaj xyuas lub cev. OF kev tiv tauj xyuas kom meej tias kev tswj cov kab ke nyob ntawm lub breaker txoj hauj lwm raug ua kom raug thiab nyab xeeb.
Ib yam li ntawd, Alarm Contact (SD) muab kev ceeb toom tseem ceeb ntawm cov xwm txheej tshwj xeeb. Nws ua haujlwm ntawm nws tus kheej ntawm Pab Pawg Sib Txuas, feem ntau hloov lub xeev tsuas yog thaum lub Miniature Circuit Breaker kev mus los tau txais vim yog overload lossis luv-circuit txhaum. Cov teeb liab sib txawv no yog qhov tseem ceeb rau kev txheeb xyuas qhov yuam kev tam sim, ua rau lub tswb nrov, lossis lub tshuab kaw lus kom ceeb toom cov neeg ua haujlwm saib xyuas tias qhov kev txiav tsis siv neeg tau tshwm sim, ua kom cov lus teb sai thiab txo qis qis. Nws ua tiav cov haujlwm tseem ceeb tiv thaiv nrog cov ntaub ntawv kuaj mob tseem ceeb.
Shunt Trip (MX) accessory qhia txog kev tswj chaw taws teeb muaj peev xwm. Cov cuab yeej siv solenoid no tso cai rau cov Miniature Circuit Breaker yuav tsum tau qhib (tripped) remotely ntawm lub teeb liab hluav taws xob, ywj siab ntawm lub xub ntiag ntawm overcurrent lossis luv-circuit mob. Qhov no yog qhov tseem ceeb rau kev siv lub zog nres thaum muaj xwm txheej ceev, kev sib koom ua ke ntawm lub tswb hluav taws xob (qhov twg cov circuits xav tau ceev de-energization), los yog tej thaj chaw deb disconnection rau kev tu lub hom phiaj. MX chav tsev muab cov txheej txheem tseem ceeb ntawm kev tswj xyuas kev ua haujlwm thiab kev cuam tshuam kev nyab xeeb.
OF (Auxiliary Contact), SD (Tswb Hu), thiab MX (Shunt Trip) cov khoom siv tau ua kom muaj txiaj ntsig zoo thiab kev nyab xeeb ntawm cov qauv MCBs. Los ntawm kev ua kom yooj yim saib xyuas cov xwm txheej hauv thaj chaw deb, muab qhov qhia yuam kev tam sim ntawd, thiab ua kom cov chaw taws teeb tawm mus, lawv hloov pauv qhov tseem ceeb. Miniature Circuit Breaker mus rau hauv ib tug ntau ntse thiab teb tivthaiv nyob rau hauv complex hluav taws xob systems. Lawv kev koom ua ke ua kom cov tshuab hluav taws xob ua haujlwm tsis yog tsuas yog ua haujlwm tau zoo xwb tab sis nrog kev txhim kho kev nyab xeeb thiab kev tswj hwm, txo qis kev pheej hmoo cuam tshuam nrog kev tshaj tawm, luv Circuit Court, thiab kev ua haujlwm txaus ntshai thoob plaws ntau yam kev siv.
