MCCB arc extinguishing system thiab trip device

Cov khoom siv hluav taws xob Moulded case (MCCB) yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob, muab kev tiv thaiv luv luv thiab overcurrent. Ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau MCCB ua haujlwm tau zoo yog nws lub kaw lus tua hluav taws xob thiab lub cuab yeej tripping. Ua ke, ob qho khoom no ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov tshuab hluav taws xob, ua rau MCCB zoo tagnrho rau ntau yam kev siv.

Lub tshuab tua hluav taws xob arc hauv MCCB yog ib qho tseem ceeb hauv kev tiv thaiv thiab tua cov arcs uas tsim tawm thaum cov cuab yeej hluav taws xob cuam tshuam kev ntws ntawm hluav taws xob. Lub luag haujlwm ntawm lub tshuab tua hluav taws xob arc yog txwv thiab faib cov arc, yog li tua nws. Qhov no ua tiav los ntawm kev siv lub chamber tua hluav taws xob arc uas nyob hauv lub thawv rwb thaiv tsev muaj zog, uas yog tsim los ntawm ntau lub grids tua hluav taws xob arc. Cov grids no ua lub luag haujlwm tseem ceeb hauv kev tua hluav taws xob arc thiab tua hluav taws xob arc ntawm cov khoom siv hluav taws xob qis.

Thaum ib qho kev sib cuag tawg vim muaj kev cuam tshuam, cov hluav taws xob ntws los ntawm thaj chaw ionized ntawm qhov kev sib cuag tsim ib lub teb sib nqus nyob ib puag ncig lub arc thiab lub tshuab tua hluav taws xob arc. Cov kab sib nqus tsav lub arc mus rau hauv lub phaj hlau, qhov chaw uas nws raug deionized thiab sib cais, yog li ntawd nws txias. Txoj hauv kev tshiab no ua kom ntseeg tau tias lub arc raug tua kom zoo, yog li tiv thaiv cov kab ke hluav taws xob los ntawm kev puas tsuaj los ntawm arcing.

Ntxiv rau qhov system tua hluav taws xob arc, lub cuab yeej tripping hauv lub molded case circuit breaker kuj tseem ceeb heev kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub tshuab hluav taws xob. Lub cuab yeej tripping ua haujlwm zoo li lub hlwb ntawm lub circuit breaker, tripping lub tshuab ua haujlwm thaum muaj luv luv lossis overcurrent. Cov circuit breakers ib txwm muaj siv cov khoom siv electromechanical trip uas tsim los muab kev tiv thaiv tseeb thiab txhim khu kev qha tiv thaiv ntau yam kev ua txhaum hluav taws xob.

Nrog kev nce qib ntawm thev naus laus zis, cov khoom siv hluav taws xob tripping tam sim no tau siv rau hauv cov khoom siv hluav taws xob molded case circuit breakers los muab kev tiv thaiv thiab kev saib xyuas zoo dua. Cov khoom siv hluav taws xob trip no txhim kho kev ua haujlwm tag nrho ntawm MCCB, muab kev tiv thaiv zoo dua tiv thaiv thermal overload, luv luv circuit thiab arcing ground faults. Kev siv cov khoom siv hluav taws xob tripping ua kom ntseeg tau tias MCCB tuaj yeem daws tau ntau yam kev siv thiab muab kev tiv thaiv txhim khu kev qha rau lub cev hluav taws xob.

Qhov kev sib xyaw ua ke ntawm lub tshuab tua hluav taws xob arc thiab lub cuab yeej tripping ua rau MCCB yog qhov kev xaiv txhim khu kev qha thiab ua haujlwm tau zoo rau kev tiv thaiv cov kab ke hluav taws xob. Lub tshuab tua hluav taws xob arc tiv thaiv thiab tua cov arcs tau zoo, thaum lub cuab yeej trip ua kom lub circuit breaker teb sai thiab raug rau cov teeb meem hluav taws xob. Lub tshuab tiv thaiv dav dav no ua rau MCCB haum rau ntau yam kev siv, suav nrog kev lag luam, kev lag luam thiab thaj chaw nyob.

Hauv kev xaus lus, lub kaw lus tua hluav taws xob arc thiab lub cuab yeej tripping hauv lub tshuab hluav taws xob molded case ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub tshuab hluav taws xob. Cov tshuab tua hluav taws xob arc tiv thaiv thiab tua hluav taws xob arcs zoo, tiv thaiv cov tshuab hluav taws xob los ntawm kev puas tsuaj. Tib lub sijhawm, lub cuab yeej tripping ua haujlwm ua lub hauv paus tswj hwm ntawm lub tshuab hluav taws xob, muab kev tiv thaiv raug thiab txhim khu kev qha tiv thaiv ntau yam kev ua txhaum hluav taws xob. Nrog cov yam ntxwv siab heev thiab cov txheej txheem tiv thaiv dav dav, MCCB zoo tagnrho rau ntau yam kev siv, ua rau nws yog thawj qhov kev xaiv rau kev xav tau kev tiv thaiv hluav taws xob.

Mutai Group tau sau ntau tshaj kaum xyoo ntawm kev tsim khoom thiab kev muag khoom hauvlub tshuab hluav taws xob, tus neeg tiv tauj, ob lub zoghloov pauv tsis siv neegthiab cov teb uas muaj feem cuam tshuam. Peb tos ntsoov yuav muaj lub sijhawm los ua haujlwm nrog koj.
