Nws yog ib hmos tsaus ntuj ntsiag to ntawm ib lub Hoobkas me me, thiab tus kws kho Tom tab tom ua haujlwm tas thaum lub tswb ceeb toom tau txiav los ntawm huab cua. Cov kab ntau lawm hauv lub hoobkas loj tau luv luv tam sim ntawd, cov hluav taws xob ntawm lub vaj huam sib luag tswj tau ci ntsa iab, thiab cov ntxhiab ntawm cov xov hlau kub hnyiab puv huab cua - yog tias qhov txhaum tsis raug nres tam sim ntawd, tag nrho cov khoom siv hauv lub hoobkas yuav kib, thiab hluav taws tuaj yeem tawg.
Tsis xav ob zaug, Tom txawm khaws nws cov khoom siv kev nyab xeeb thiab khiav mus rau chav faib hluav taws xob ntawm lub Hoobkas. Nyob ntawd, nws pom lub tshuab hluav taws xob nqus tsev uas ib txwm muaj - lub cuab yeej xim grey, ruaj khov ntsia rau ntawm phab ntsa, tsis muaj cov ntxaij vab tshaus zoo nkauj lossis cov chaw taws teeb tswj, tsuas yog lub tes tuav thiab ob peb lub teeb qhia. Nrog tes ruaj khov, nws rub lub tes tuav kom ruaj khov: lub suab "thud" me ntsis rov qab los thaum lub tshuab hluav taws xob ua haujlwm, txiav hluav taws xob rau cov kab hluav taws xob tsis ua haujlwm hauv ib pliag. Cov hluav taws xob tau ploj mus, lub tswb ceeb toom ntsiag to, thiab kev puas tsuaj tau zam. Txawm hais tias qaug zog los ntawm kev maj nrawm, Tom paub: lub tshuab hluav taws xob nqus tsev yooj yim, tsis muaj kev zam txim tau cawm lub Hoobkas ntawm kev puas tsuaj loj heev.
Zaj dab neeg ntawm Tom tsis yog ib yam tshwj xeeb. Tau ntau xyoo lawm, lub tshuab hluav taws xob nqus tsev ib txwm muaj tau sawv ua ib tug phab ej uas tsis muaj leej twg paub hauv cov tshuab hluav taws xob thoob ntiaj teb. Tej zaum nws yuav tsis muaj cov yam ntxwv ntse ntawm kev hloov kho tshiab niaj hnub no, tab sis nws qhov kev ntseeg tau thiab kev ua haujlwm tseem ceeb ua rau nws yog tus neeg saib xyuas kev nyab xeeb ntawm lub zog hluav taws xob uas tseem ceeb heev - ib qho uas tiv thaiv cov khoom siv, tiv thaiv kev raug mob, thiab ua kom cov tshuab hluav taws xob khiav tau zoo.
Yog li, lub tshuab hluav taws xob nqus tsev (VCB) yog dab tsi, thiab vim li cas nws thiaj li tseem ceeb?
Hauv nws lub hauv paus, VCB ib txwm muaj yog lub cuab yeej tiv thaiv hluav taws xob uas tsim los cuam tshuam cov hluav taws xob tsis zoo (xws li luv luv lossis overloads) hauv cov kab ke hluav taws xob nruab nrab thiab siab.Qhov zoo tshaj plaws ntawm nws yog nyob rau hauv lub tshuab nqus tsev uas tua hluav taws xob arc, uas yog lub plawv ntawm lub cuab yeej. Thaum muaj qhov txhaum tshwm sim, cov khoom sib txuas ntawm lub breaker yuav sib cais hauv qhov chaw nqus tsev, uas ua rau tua hluav taws xob arc (lub hluav taws xob txaus ntshai uas tshwm sim los ntawm cov hluav taws xob tam sim no) hauv milliseconds. Qhov kev tua hluav taws xob sai no tiv thaiv kev kub hnyiab ntawm hluav taws xob, tiv thaiv lwm yam khoom siv hluav taws xob, thiab cais cov kab hluav taws xob kom cov kab ke ua haujlwm tas li.
PEOPLE kuj tsim thiab muab cov khoom siv hluav taws xob nqus tsev, thiab VCBs siv dav hauv cov xwm txheej uas qhov yooj yim thiab kev ntseeg tau raug muab tso ua ntej:
● Cov chaw tsim khoom me me mus rau nruab nrab: Zoo li qhov hauv zaj dab neeg Tom, qhov chaw uas lawv tiv thaiv cov kab tsim khoom los ntawm kev ua txhaum hluav taws xob.
● Cov chaw faib hluav taws xob hauv zos: Tiv thaiv kev muab hluav taws xob rau cov chaw nyob thiab cov chaw ua lag luam.
● Cov tsev lag luam thiab cov chaw ua haujlwm: Xyuas kom muaj kev nyab xeeb ntawm kev siv hluav taws xob hauv cov chaw uas xav tau hluav taws xob nruab nrab.
● Cov chaw ua lag luam uas muaj kev xav tau hluav taws xob yooj yim: Qhov twg cov yam ntxwv ntse nyuaj tsis tsim nyog, tab sis kev ntseeg tau tsis sib tham.
Txawm hais tias thev naus laus zis ntse tab tom hloov pauv cov tshuab fais fab, cov tshuab hluav taws xob nqus tsev ib txwm tseem yog lub hauv paus ntawm kev nyab xeeb hluav taws xob. Lawv pheej yig, yooj yim rau kev saib xyuas, thiab ua kom siv tau ntev - cov yam ntxwv ua rau lawv zoo tagnrho rau ntau daim ntawv thov thoob ntiaj teb.
Ib yam li Tom ua haujlwm sai sai nrog lub VCB ntawm tes hmo ntawd, cov khoom siv no ua haujlwm ntsiag to tom qab qhov xwm txheej, npaj txhij los pab thiab tiv thaiv yam tseem ceeb. Lawv tej zaum yuav tsis yog cov thev naus laus zis siab heev, tab sis lawv lub luag haujlwm ua tus saib xyuas kev nyab xeeb ntawm lub zog hluav taws xob yog qhov tseem ceeb heev.
