Molded Case Circuit Breaker: Xyuas kom muaj kev nyab xeeb thiab txhim khu kev qha kev faib hluav taws xob

Cov Khoom Siv Hluav Taws Xob Moulded Case

A Lub tshuab hluav taws xob molded case circuit breaker (MCCB)yog ib hom circuit breaker siv dav rau kev tiv thaiv hluav taws xob hauv cov chaw lag luam thiab cov chaw lag luam vim nws muaj peev xwm muab kev tiv thaiv txhim khu kev qha thiab muaj kev nyab xeeb tiv thaiv overcurrent, luv luv circuits thiab lwm yam hluav taws xob faults. Hauv tsab xov xwm no, peb yuav saib tob tob txogCov MCCBthiab tham txog lawv cov yam ntxwv, cov ntsiab cai ua haujlwm, kev tsim kho, thiab cov ntawv thov.

Cov yam ntxwv ntawm MCCBs

MCCBs tau tsim los nrog ntau yam haujlwm uas pab tiv thaiv cov kab ke hluav taws xob kom muaj kev nyab xeeb thiab txhim khu kev qha. Qee qhov tseem ceeb ntawm MCCB suav nrog:

• Muaj peev xwm tawg siab:Cov khoom siv hluav taws xob molded casemuaj peev xwm rhuav cov hluav taws xob mus txog ntau txhiab amperes, ua rau lawv zoo tagnrho rau cov ntawv thov muaj zog heev.
• Thermal-magnetic trip mechanism:Cov khoom siv hluav taws xob molded casesiv lub tshuab thermal-magnetic trip los ntes thiab teb rau overcurrent thiab luv circuits. Thermal trip elements teb rau overloads, thaum magnetic trip elements teb rau luv circuits.
• Kev Teeb Tsa Hloov Tau: MCCBs muaj kev teeb tsa hloov tau, uas tso cai rau lawv teeb tsa rau qib tsim nyog rau daim ntawv thov xav tau.
• Ntau yam ntawm qhov loj ntawm lub thav duab: MCCBs muaj ntau yam qhov loj ntawm lub thav duab, uas tso cai rau lawv siv rau hauv ntau yam kev siv. Lub hauv paus ntsiab lus ua haujlwm ntawm molded case circuit breaker Lub hauv paus ntsiab lus ua haujlwm ntawm MCCB yog raws li lub tshuab thermal-magnetic tripping. Lub thermal trip element hnov ​​​​​​qhov kub uas tsim los ntawm cov dej ntws ntawm tam sim no hauv lub voj voog thiab trips lub circuit breaker thaum tam sim no tshaj qhov ntsuas trip. Lub magnetic trip element hnov ​​​​​​qhov magnetic field tsim los ntawm luv luv circuit hauv lub voj voog, tripping lub circuit breaker yuav luag tam sim ntawd. Cov qauv ntawm molded case circuit breaker
• Lub MCCB muaj ib lub tsev yas molded uas muaj lub tshuab mus ncig, cov neeg sib cuag thiab cov khoom nqa tam sim no.
• Cov kev sib cuag yog ua los ntawm cov khoom siv conductive heev xws li tooj liab, thaum lub tshuab mus ncig muaj cov kab bimetallic thiab lub kauj sib nqus.

Daim ntawv thov ntawm MCCB

MCCBs feem ntau siv rau hauv ntau yam kev siv xws li:

• Lub kaw lus faib hluav taws xob
• Chaw Tswj Xyuas Lub Cev Muaj Zog
• Cov tshuab siv hauv kev lag luam
• Cov Transformers
• Cov khoom siv hluav taws xob

xaus lus

Cov khoom siv hluav taws xob uas muaj pwm (molded case circuit breakers) yog cov khoom siv uas ntseeg tau thiab siv tau zoo heev rau kev tiv thaiv hluav taws xob. Lawv txoj kev tsim kho thiab cov yam ntxwv ua rau lawv zoo tagnrho rau kev siv ntau yam xws li transformers, power distribution systems, thiab motor control centers. Lawv lub tshuab thermal-magnetic trip, muaj peev xwm tawg tau zoo thiab hloov kho qhov chaw teeb tsa tau ua rau lawv yog qhov kev xaiv nrov rau kev tiv thaiv hluav taws xob hauv cov chaw lag luam thiab cov chaw ua haujlwm.
