Cov Hluav Taws Xob Hluav Taws XobCov Neeg Ua Siab Zoo ntawm Kev Nyab Xeeb Hluav Taws Xob uas Tsis Tau Txais Kev Qhuas
Hauv ntiaj teb ntawm cov tshuab hluav taws xob, cov cuab yeej hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm tag nrho cov kev teeb tsa. Nws yog ib lub cuab yeej yooj yim tab sis muaj tswv yim tsim los tiv thaiv cov circuits ntawm kev puas tsuaj los ntawm overcurrent thiab luv luv circuits. Cov cuab yeej hluav taws xob ua haujlwm ua lub tshuab tsis ua haujlwm, cuam tshuam cov hluav taws xob ntws thaum pom cov xwm txheej tsis zoo, yog li tiv thaiv cov kev phom sij xws li hluav taws xob hluav taws xob thiab kev puas tsuaj ntawm cov khoom siv.
Lub hauv paus ntsiab lus ntawm lub circuit breaker yog qhib lub circuit thaum cov hluav taws xob ntau tshaj qhov txwv. Qhov no ua tiav los ntawm lub tshuab uas siv cov hlau nplaum bimetallic lossis lub electromagnet los tsoo lub circuit breaker thaum pom tias muaj hluav taws xob ntau dhau. Thaum lub circuit raug cuam tshuam, lub circuit breaker tuaj yeem rov pib dua los ntawm tes kom rov qab tau dej, ua rau nws yog lub cuab yeej siv tau dua.
Muaj ntau hom circuit breakers uas tsim los rau ntau yam kev siv, suav nrog cov chaw nyob, cov chaw lag luam, thiab cov chaw ua haujlwm. Hauv cov tsev nyob, cov miniature circuit breakers (MCBs) feem ntau siv los tiv thaiv cov circuits ib leeg, xws li cov rau teeb pom kev zoo, cov khoom siv hluav taws xob, thiab cov qhov (sockets). Cov MCBs no me me thiab tuaj yeem ntsia tau yooj yim rau hauv cov vaj huam sib luag hluav taws xob, muab txoj hauv kev yooj yim thiab zoo los tiv thaiv lub tsev lub tshuab hluav taws xob.
Rau cov chaw ua lag luam thiab kev lag luam, cov circuit breakers loj dua xws li molded case circuit breakers (MCCB) thiab air circuit breakers (ACB) yog siv los tiv thaiv cov hluav taws xob siab dua thiab cov hluav taws xob tam sim no. Muaj peev xwm tswj tau cov khoom siv hluav taws xob loj dua, cov circuit breakers hnyav no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob nyuaj hauv cov tsev lag luam, cov chaw tsim khoom thiab cov chaw tsim hluav taws xob.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov circuit breakers yog lawv lub peev xwm teb tau sai thiab raug rau cov xwm txheej overcurrent, yog li txo qhov kev pheej hmoo ntawm kev raug mob hluav taws xob. Tsis zoo li cov fuses, uas yuav tsum tau hloov tom qab ua haujlwm, cov circuit breakers tuaj yeem rov pib dua, ua rau lawv yooj yim dua thiab pheej yig dua rau kev tiv thaiv cov circuits.
Ntxiv rau lawv txoj haujlwm tseem ceeb ntawm kev tiv thaiv overcurrent, cov circuit breakers niaj hnub no muaj cov yam ntxwv siab heev xws li kev tiv thaiv qhov av txhaum, kev kuaj pom qhov txhaum arc, thiab kev saib xyuas deb. Cov yam ntxwv ntxiv no ua rau muaj kev nyab xeeb thiab kev ua tau zoo ntawm cov kab ke hluav taws xob, ua rau cov circuit breakers yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no.
Thaum thev naus laus zis txuas ntxiv mus, kev tsim cov cuab yeej hluav taws xob ntse kuj tau nce qib. Cov cuab yeej hluav taws xob ntse muaj cov sensors thiab kev sib txuas lus uas ua rau lawv muab cov ntaub ntawv tiag tiag ntawm cov yam ntxwv hluav taws xob thiab qhov xwm txheej ntawm lub kaw lus. Qhov no ua rau muaj kev saib xyuas ua ntej thiab kev daws teeb meem nyob deb, ua rau kev ntseeg siab thiab kev ua haujlwm ntawm kev teeb tsa hluav taws xob nce ntxiv.
Txhua yam hais los saum toj no, tej zaum cov circuit breakers yuav tsis tau txais kev saib xyuas tas li, tab sis lawv yog ib qho tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab txhim khu kev qha hluav taws xob. Txij li cov tsev mus rau cov chaw ua haujlwm, cov circuit breakers ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev phom sij hluav taws xob thiab tswj kev ua haujlwm ntawm cov khoom siv hluav taws xob. Raws li qhov kev thov rau cov kev daws teeb meem hluav taws xob uas siv hluav taws xob zoo thiab ntse txuas ntxiv loj hlob, qhov tseem ceeb ntawm cov circuit breakers hauv kev tiv thaiv cov kab ke hluav taws xob yuav pom tseeb dua hauv xyoo tom ntej.
