qhia:
Hauv hluav taws xob engineering,molded rooj plaub Circuit Court breakers (MCCBs) yog cov khoom tseem ceeb hauv kev tiv thaiv hluav taws xob los ntawm overloads, luv circuits thiab lwm yam kev ua tsis tiav.MCCBsyog feem ntau siv nyob rau hauv ntau yam kev siv hauv vaj tse, kev lag luam thiab kev lag luam kev lag luam kom ntseeg tau tias kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov tshuab hluav taws xob.Hauv tsab xov xwm no, peb yuav tshawb txog cov ntawv thov, cov yam ntxwv, thiab kev txiav txim siab ntawm MCCBs.
Daim ntawv thov ntawmmolded rooj plaub Circuit Court breaker:
MCCBsyog siv nyob rau hauv ntau yam kev siv xws li:
1. Cov ntawv thov kev lag luam: MCCBs feem ntau siv rau hauv cov ntawv thov kev lag luam los muab kev tiv thaiv hluav taws xob tiv thaiv overloads, luv circuits, thiab lwm yam kev ua txhaum.Cov ntawv thov no suav nrog kev tsim khoom, roj thiab roj, mining thiab lwm yam kev lag luam ib puag ncig.
2. Cov ntawv thov kev lag luam: Moulded case circuit breakers yog siv hauv kev lag luam, xws li cov khw muag khoom, tsev so, tsev ua haujlwm, thiab lwm yam, kom ntseeg tau tias kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov tshuab hluav taws xob.
3. Cov ntawv thov nyob hauv: Moulded case circuit breakers yog siv rau hauv cov ntawv thov hauv tsev kom muaj kev nyab xeeb ntawm cov neeg nyob hauv tsev.Nws tau nruab rau hauv cov thawv xa khoom los tiv thaiv circuits los ntawm hluav taws xob tsis raug.
Cov yam ntxwv ntawm molded case Circuit Court breakers:
1. Rated tam sim no: Cov ntsuas tam sim no ntawm molded case circuit breakers yog txawv, xws li ntawm ob peb amperes mus rau ntau txhiab amperes.Qhov no feature enables nws yuav siv tau nyob rau hauv ntau yam kev siv.
2. Tripping yam ntxwv: Lub molded case Circuit Court breaker muaj ib tug tripping yam ntxwv, uas yuav xyuas kom meej tias lub Circuit Court mus txawv tebchaws nyob rau hauv cov kev tshwm sim ntawm hluav taws xob txhaum los tiv thaiv kev puas tsuaj ntxiv.Cov yam ntxwv mus txawv tebchaws tuaj yeem yog thermal lossis sib nqus.
3. Muaj peev xwm tawg: Moulded case Circuit Breaker muaj peev xwm tawg siab thiab tuaj yeem tiv taus qhov txhaum loj tam sim no yam tsis muaj kev puas tsuaj.Qhov no ua kom ntseeg tau tias lub voj voog tiv thaiv kev puas tsuaj.
4. Selectivity: Lub molded case Circuit Court breaker muab kev xaiv rau lub tshuab hluav taws xob, uas yog, tsuas yog cov molded case Circuit Court breaker ze tshaj plaws rau kev ua txhaum kev mus ncig, thaum lwm yam circuits hauv hluav taws xob tsis cuam tshuam.
Kev ceev faj rau kev xaiv molded case Circuit Court breakers:
1. Rated tam sim no: Thaum xaiv lub molded case Circuit Court breaker, qhov ntsuas tam sim no ntawm lub tshuab hluav taws xob yuav tsum tau txiav txim siab kom ntseeg tau tias cov molded case circuit breaker tuaj yeem tiv taus qhov tam sim no yam tsis muaj tripping.
2. Hom kev ua tsis tiav: Hom kev ua tsis tiav uas MCCB tsim los tiv thaiv yog qhov tseem ceeb thaum xaiv MCCB.Piv txwv li, qee qhov MCCBs tau tsim los tiv thaiv thermal tsis ua haujlwm, thaum lwm tus yog tsim los tiv thaiv kev sib nqus tsis ua haujlwm.
3. Ambient kub: Qhov kub thiab txias ntawm ib puag ncig qhov chaw molded case Circuit Court breaker nyob kuj yog ib qho tseem ceeb xav txog.MCCB muaj qhov ntsuas kub thiab nws yuav tsis ua haujlwm zoo yog tias qhov ntsuas kub ib puag ncig tshaj qhov ntsuas ntawm MCCB.
Hauv cov ntsiab lus: MCCB yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob vim nws muab kev tiv thaiv hluav taws xob tsis zoo.Nws muaj qhov sib txawv ntsuas tam sim no, tripping yam ntxwv thiab tawg muaj peev xwm, yog li nws tsim nyog rau kev siv sib txawv.Thaum xaiv MCCB, qhov ntsuas tam sim no, hom kev ua txhaum, thiab qhov ntsuas kub yuav tsum raug txiav txim siab kom ua haujlwm tau zoo.
