Lub tshuab hluav taws xob hluav taws xob tau siv nyob rau lub sijhawm tshwj xeeb kom kaw, thauj khoom thiab ua txhaum qhov tsis sib xws ntawm lub cuab yeej hloov pauv tam sim no, los ntawm kev ua haujlwm lossis kaw hluav taws xob, faib ib leeg, ob tus ncej, peb tus ncej, plaub tus ncej. Kev sib cuag tseem ceeb, sib cuag pab, hu xov tooj ceeb toom, tawm mus txawv tebchaws, mus ncig tsis muaj zog thiab lwm yam qauv tseem ceeb, cov kab ntawv me me hauv qab no rau koj los qhia cov ntsiab lus tseem ceeb hauv kev nthuav dav.
Ua ntej, txoj cai ua haujlwm ntawm lub tshuab hluav taws xob
1, kev sib cuag tseem ceeb ntawm cov hluav taws xob hluav taws xob qis hluav taws xob tau ua haujlwm los yog kaw hluav taws xob. Tom qab kev sib cuag tseem ceeb raug kaw, txoj kev mus ncig dawb tau xauv lub ntsiab lus sib tham hauv txoj haujlwm kaw.
2. Cov kauj ntawm kev mus ncig tam sim no thiab cov khoom siv tiv thaiv ntawm cov cua sov mus los yog nyob rau hauv kab nrog lub hauv paus tseem ceeb, thiab cov kauj ntawm qhov qis dua kev mus los yog nyob rau hauv kev sib txuas nrog lub zog xa khoom. Thaum cov khoom siv hluav taws xob luv luv lossis hnyav dhau, lub cev ntawm kev mus los tam sim no tau rub los ua qhov kev mus ncig dawb ua haujlwm, thiab kev sib cuag tseem ceeb raug txiav tawm ntawm lub hauv paus tseem ceeb. Thaum lub voj voog hla dhau, cov khoom siv cua sov ntawm cov cua sov yuav sov thiab khoov cov phaj bimetal, thawb cov txheej txheem pub dawb mus rau hauv kev nqis tes ua.
3. Thaum lub Circuit Court undervoltage, lub armature ntawm undervoltage dawm tau tso tawm, uas tseem ua rau txoj kev mus txawv tebchaws pub dawb ua. Shunt tripping ntaus ntawv yog siv los ua chaw taws teeb tswj, hauv kev ua haujlwm ib txwm muaj, lub kauj tsis muaj zog, xav tau kev tswj nyob deb, nias lub pob pib, ua kom lub zog muaj zog.
Qhov thib ob, lub hauv paus tseem ceeb ntawm lub tshuab hluav taws xob
1, kev sib cuag tseem ceeb
Los ntawm kev thauj khoom tam sim no rau lub sijhawm ntev, nws tau txuas nrog tom qab kaw, thiab txuas thawj zaug thaum qhib. Qhov kev sib cuag tseem ceeb yog nyob ntawm txhua qhov hloov pauv.
2, pabcuam kev sib cuag
Kev sib txuas tau txuas nrog cov tshuab nrog kev sib faib thiab kaw cov txheej txheem ntawm lub tshuab hluav taws xob tseem ceeb feem ntau yog siv rau kev nthuav tawm ntawm kev sib faib thiab kaw lub xeev ntawm lub tshuab hluav taws xob. Nws tau txuas nrog hauv kev tswj hluav taws xob ntawm lub tshuab hluav taws xob los ntawm kev sib cais thiab kaw ntawm lub tshuab hluav taws xob kom tswj lossis cuam tshuam cov khoom siv hluav taws xob cuam tshuam.
3. Tswb tiv tauj
Siv rau kev sib tsoo lub tswb sib tsoo lub tswb hu xov tooj, thiab kev sib cuag tsuas yog thaum lub tshuab hluav taws xob cov ntsiab lus tawg tawm, feem ntau yog siv rau kev thauj khoom Circuit Court breaker overload luv Circuit Court lossis nyob rau hauv qhov hluav taws xob thiab ua tsis tiav, thiab qee zaum dawb mus ncig, tswb hu los ntawm qhov qub mus rau ib txwm qhib nyob ze txoj haujlwm, dhau mus rau kab pabcuam ntu lossis lub tswb, thiab lwm yam, hauv cov zaub lossis nco txog qhov ua txhaum qhov hla lub Circuit Court breaker xwm txheej.
4. Shunt tripping ntaus ntawv
Shunt trip yog kev mus los zoo siab los ntawm qhov hluav taws xob qhov hluav taws xob uas nws qhov hluav taws xob ywj siab ntawm qhov tseem ceeb hluav taws xob hluav taws xob. Shunt tripping ntaus ntawv yog cov khoom siv rau kev ua haujlwm nyob deb. Lub tshuab tawg tuaj yeem ntseeg tau tawg thaum lub zog muab hluav taws xob sib npaug rau txhua qhov hluav taws xob nruab nrab ntawm 70% thiab 110% ntawm qhov ntsuas ntsuas qhov ntsuas hluav taws xob. Shunt mus txawv tebchaws yog lub sijhawm ua haujlwm luv, lub zog hluav taws xob lub sijhawm feem ntau tsis tuaj yeem tshaj 1S, txwv tsis pub cov hlau yuav raug hlawv.
5. Kev mus los tsis txaus
Nyob rau hauv qhov kev mus ncig qhov hluav taws xob nyob ntawm nws qhov dav hlau qhov hluav taws xob poob rau qhov tau teev tseg, ua rau lub tshuab hluav taws xob cuam tshuam nrog ncua lossis tsis ncua ncua txuas ib qho kev mus, thaum lub zog hluav taws xob poob qis (lossis txawm tias qeeb) mus rau 70% thiab 35% ntawm qhov ntsuas hluav taws xob ntau Cov cuab yeej siv hluav taws xob qis yuav tsum ua haujlwm, lub zog poob qis hauv lub zog hluav taws xob hluav taws xob sib npaug li 35% ntawm qhov ntsuas ua haujlwm qhov kev mus ncig ua haujlwm, Kev tawm mus qis qis yuav tsum tiv thaiv kev kaw lub kaw lus; Thaum lub zog hluav taws xob muab hluav taws xob sib npaug lossis ntau dua 85% ntawm qhov ntsuas hluav taws xob ua haujlwm ntawm qhov tsis txaus ntseeg, lub tshuab hluav taws xob yuav tsum raug kaw zoo nyob hauv lub xeev kub.
