MCCB yog dab tsi?

Cov khoom siv hluav taws xob uas muaj pwm (molded case circuit breakers) yog cov khoom siv tiv thaiv hluav taws xob uas tsim los tiv thaiv lub voj voog hluav taws xob ntawm cov hluav taws xob ntau dhau. Cov hluav taws xob ntau dhau no tuaj yeem tshwm sim vim muaj kev thauj khoom ntau dhau lossis luv luv. Cov khoom siv hluav taws xob uas muaj pwm no tuaj yeem siv tau rau ntau yam voltages thiab frequencies nrog rau qhov txwv qis thiab siab dua ntawm kev hloov kho qhov chaw. Ntxiv nrog rau cov txheej txheem tripping, MCCBs kuj tseem siv tau ua cov keyboards txiav tes thaum muaj xwm txheej ceev lossis kev ua haujlwm txij nkawm. MCCBs tau raug qauv thiab kuaj rau overcurrent, voltage surge, thiab kev tiv thaiv qhov txhaum kom ntseeg tau tias muaj kev nyab xeeb hauv txhua qhov chaw thiab kev siv. Lawv ua haujlwm zoo li lub khawm pib dua rau lub voj voog hluav taws xob kom txiav hluav taws xob thiab txo qhov kev puas tsuaj los ntawm kev thauj khoom ntau dhau, av txhaum, luv luv, lossis thaum tam sim no tshaj qhov txwv tam sim no.

Daim Ntawv Thov MCCB

MCCB lossis fuse yog ib qho khoom siv hluav taws xob uas feem ntau siv hauv kev lag luam los tiv thaiv cov khoom siv hluav taws xob thiab cov kab ke. Hauv lub neej txhua hnub, MCCB siv dav. Qee qhov kev siv MCCB feem ntau tau piav qhia hauv qab no.

1. Kev faib hluav taws xob: MCCB tuaj yeem pab cov neeg teeb tsa faib cov khoom siv hluav taws xob rau ntau yam khoom siv hluav taws xob. Los ntawm MCCB, cov neeg siv tuaj yeem tswj hwm kev faib hluav taws xob thiab tam sim no ntawm txhua lub cuab yeej kom muaj kev nyab xeeb dua.
2. Kev tiv thaiv luv luv: Lub luag haujlwm tseem ceeb ntawm MCCB yog txiav tawm lub voj voog thaum muaj luv luv tshwm sim. Qhov no zam kev puas tsuaj rau cov khoom siv, tso tawm cov tshuaj phom sij xws li hluav taws.
3. Kev tiv thaiv overload: Zoo ib yam li kev tiv thaiv luv luv, MCCB kuj tseem tuaj yeem tiv thaiv cov khoom siv kom tsis txhob muaj overloaded. Qhov no tuaj yeem ua tiav los ntawm kev teeb tsa cov circuit breakers kom tsis txhob muaj kev puas tsuaj hluav taws xob los ntawm kev overloaded cov khoom siv.
4. Kev tiv thaiv ntawm lub tshuab hluav taws xob: MCCB siv dav hauv kev nrhiav thiab tiv thaiv cov tshuab hluav taws xob loj. Nws tuaj yeem saib xyuas kev ua haujlwm ib txwm ntawm lub tshuab hluav taws xob, nrhiav teeb meem thiab qhib lub kaw lus tiv thaiv Circuit Court breaker.
5. Kev tiv thaiv lub tshuab hluav taws xob: MCCB tuaj yeem tiv thaiv lub tshuab hluav taws xob kom tsis txhob thauj khoom ntau dhau thiab saib xyuas lub tshuab hluav taws xob kub dhau tib lub sijhawm.
6. Kev tiv thaiv lub tog raj kheej txav tau: MCCB siv dav hauv cov pob zeb ua vaj tse, cement thiab cov khoom siv crushers. Nws ntes tau cov circuits luv luv thiab cov khoom siv ntau dhau, yog li tiv thaiv cov khoom siv kom tsis txhob puas tsuaj.

Xaus lus, MCCBs siv dav dav thiab ua lub luag haujlwm tseem ceeb hauv ntau yam hluav taws xob thiab tshuab. Thaum xaiv MCCB, ntau yam tshwj xeeb yuav tsum tau xav txog kom zoo zoo kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub kaw lus, suav nrog lub peev xwm nqa tam sim no, kev ua haujlwm zoo, thaj chaw siv tau, thiab lwm yam tseem ceeb. Peb lub tuam txhab hais txog txoj cai zoo ntawm "khoom zoo yog lub hauv paus ntawm kev ciaj sia ntawm lub koom haum; kev txaus siab ntawm cov neeg siv khoom tuaj yeem yog qhov pib thiab qhov kawg ntawm lub tuam txhab; kev txhim kho tas mus li yog kev nrhiav neeg ua haujlwm tas mus li" nrog rau lub hom phiaj tas mus li ntawm "lub koob npe nrov ua ntej, tus neeg yuav khoom ua ntej" rau High definition MCCB OEM ODM Chaw Tsim Khoom CJMM7DC-630 DC 3p 400A Moulded Case Circuit Breaker, Peb kuj xyuas kom meej tias koj cov khoom yuav raug tsim thaum siv qhov zoo tshaj plaws thiab kev ntseeg siab.
