Lub tshuab hluav taws xob hluav taws xob tau siv nyob rau lub sijhawm tshwj xeeb kom kaw, thauj khoom thiab qhib qhov hloov pauv hloov pauv tam sim no, los ntawm kev ua haujlwm lossis kaw hluav taws xob, ib leeg, ob tug ncej, peb tug ncej, plaub tug ncej. Muaj kev sib cuag tseem ceeb, koom nrog kev sib cuag, hu xov tooj ceeb toom, tso tawm tsis raug, tso tawm qhov hluav taws xob qis thiab lwm yam txheej txheem 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 hauv kev 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 qhov kev sib cuag tseem ceeb raug kaw, txoj hauv kev hla tsis pub xauv lub ntsiab lus tiv toj ntawm txoj haujlwm kaw.
2. Cov kauj ntawm qhov tso tawm tam sim no thiab cov khoom siv cua sov ntawm cov cua sov tso tawm tau txuas nrog hauv kab nrog lub hauv paus tseem ceeb, thiab cov kauj ntawm qhov tso tawm qis qis tau txuas nrog ua ke nrog cov khoom siv hluav taws xob. Thaum lub Circuit Court luv-circuited lossis hnyav dhau lawm, lub armature ntawm overcurrent tripping ntaus ntawv raug kaw kom ua rau cov cuab yeej pub dawb txav mus thiab qhov tseem ceeb sib txuas tsis txuas lub hauv paus tseem ceeb. Thaum lub voj voog hla dhau, cov khoom siv cua sov ntawm lub tshuab tso cua sov ua kom sov thiab khoov cov ntawv bimetallic, uas thawb lub tshuab tso tawm dawb los ua.
3. Thaum qhov hluav taws xob nyob hauv qhov hluav taws xob, lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob qis qis tau tso tawm, uas tseem ua rau lub tshuab ua haujlwm pub dawb txav mus los. Shunt mus txawv tebchaws yog siv rau kev tswj chaw taws teeb. Hauv kev ua haujlwm ib txwm muaj, lub kauj hluav taws xob raug kaw. Thaum xav tau kev tswj hwm qhov 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, hloov tom qab kaw, tua tawm ua ntej. Tus tswv kev sib cuag yog ib txwm muaj rau txhua qhov hloov pauv.
2. Pab tiv tauj
Kev sib txuas nrog kev sib txuas tseem ceeb ntawm lub tshuab hluav taws xob feem ntau yog siv rau cov zaub ntawm lub tshuab hluav taws xob' qhib thiab kaw lub xeev. Nws txuas nrog kev tswj hluav taws xob ntawm lub tshuab hluav taws xob los ntawm kev qhib thiab kaw ntawm lub tshuab hluav taws xob los 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 mus txawv tebchaws
Shunt trip yog kev mus los zoo siab los ntawm qhov hluav taws xob, nws qhov hluav taws xob yog ywj siab ntawm qhov tseem ceeb hluav taws xob hluav taws xob. Shunt tripper yog ib qho khoom siv ntxiv rau kev khiav hauj lwm nres. Thaum qhov hluav taws xob muab hluav taws xob sib npaug rau ib qho hluav taws xob nruab nrab ntawm 70% thiab 110% ntawm qhov ntsuas ntsuas qhov ntsuas hluav taws xob, lub tshuab hluav taws xob tuaj yeem txuas tau zoo. Shunt mus txawv tebchaws yog kev ua haujlwm luv-sijhawm, lub sijhawm siv hluav taws xob feem ntau yuav tsum tsis pub tshaj 1S, txwv tsis pub txoj kab yuav raug hlawv.
5. Undervoltage tso tawm ntaus ntawv
Nyob rau hauv qhov kev mus ncig qhov hluav taws xob nyob ntawm nws qhov dav hlau qhov hluav taws xob poob mus rau qhov tau teev tseg, ua rau lub tshuab hluav taws xob tawg nrog ncua lossis tsis ncua ncua txuas ib qho kev mus, thaum lub zog fais fab tuag 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 tau sib npaug li 35% ntawm qhov ntsuas qhov ua haujlwm voltage mus, Kev tso tawm qis yuav tsum tiv thaiv kev thaiv hluav taws xob los ntawm kev kaw; 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 lub zog hluav taws xob qis, lub tshuab hluav taws xob yuav tsum raug kaw kom ntseeg tau nyob rau hauv cov xwm txheej kub.
