Dab tsi yog qhov ua rau thiab tuav txoj hauv kev ntawm tripping ntawm kev tiv thaiv hluav taws xob ntawm lub tshuab hluav taws xob?

Thaum peb siv lub tshuab hluav taws xob, peb yuav ntsib qhov tshwm sim ntawm tripping vim qhov kev ua ntawm kev tiv thaiv hluav taws xob. Qhov no yog ib qho tshwm sim feem ntau hauv kev siv cov tshuab hluav taws xob. Nws yog ib qho tseem ceeb heev rau cov neeg ua hauj lwm uas siv thiab tswj lub tshuab hluav taws xob kom nkag siab txog cov laj thawj ntawm kev sib tsoo thiab cov txheej txheem tuav.

I. Yog vim li cas

1. Transient overvoltage:

- Txhais: Transient overvoltage yog hais txog qhov tshwm sim hauv lub zog hluav taws xob uas qhov system voltage nce siab hauv lub sijhawm luv vim yog vim li cas xws li luv luv Circuit Court, arc grounding, switching operations, lossis xob laim ntaus.

- Kev cuam tshuam: Transient overvoltage ua rau muaj kev hem thawj rau lub rwb thaiv tsev ntawm lub tshuab hluav taws xob. Nws tuaj yeem ua rau lub rwb thaiv tsev ntawm cov windings tawg, thiab tom qab ntawd ua rau lub voj voog luv luv lossis luv luv Circuit Court. Tsis tas li ntawd, cov overvoltage tsis ntev los no tseem yuav ua rau muaj kev kub ntxhov hauv lub tshuab hluav taws xob, uas ua rau muaj qhov kub thiab txias ntau dhau, thiab tej zaum yuav ua rau muaj kev cuam tshuam ntawm kev tiv thaiv hluav taws xob.

2. Overcurrent:

- Txhais: Overcurrent yog hais txog qhov tshwm sim uas lub hwj huam mov tam sim no ntawm lub tshuab hluav taws xob tshaj nws cov nqi ntsuas.

- Yog vim li cas: Sudden hloov nyob rau hauv load, short-circuit faults, los yog ib tug poob nyob rau hauv qhov system voltage, thiab lwm yam, tej zaum yuav tag nrho cov ua rau tshwm sim ntawm overcurrent nyob rau hauv lub generator.

- Kev cuam tshuam: Lub sijhawm ntev overcurrent yuav ua rau cov cua ntawm lub tshuab hluav taws xob overheat, ua rau cov laus ntawm cov rwb thaiv tsev, thiab tseem tuaj yeem ua rau kub hnyiab ntawm cov cua kub hauv qhov hnyav. Nyob rau tib lub sijhawm, overcurrent kuj tuaj yeem ua rau muaj kev vibration thiab suab nrov ntawm lub tshuab hluav taws xob, cuam tshuam rau kev ua haujlwm ruaj khov ntawm cov khoom siv.

3. Voltage poob:

- Txhais: Ib qho hluav taws xob poob yog hais txog qhov tshwm sim uas qhov hluav taws xob theem hauv lub zog hluav taws xob qis dua tus nqi ib txwm muaj.

- Yog vim li cas: Ib qho kev nce hauv qhov system load, nce hauv kab impedance, tsis muaj lub zog reactive, thiab lwm yam, tej zaum yuav tag nrho ua rau lub zog poob.

- Kev cuam tshuam: Ib qho kev poob qis yuav cuam tshuam rau lub zog tso zis thiab kev ua haujlwm ntawm lub tshuab hluav taws xob. Nyob rau tib lub sijhawm, nws tuaj yeem ua rau lub zog excitation ntawm lub tshuab hluav taws xob tsis ruaj khov, thiab tom qab ntawd ua rau lub zog ntawm kev tiv thaiv hluav taws xob.

II. Phenomena

1. Tripping ntawm lub ntsiab hloov ntawm lub tshuab hluav taws xob:

- Lub tripping ntawm lub ntsiab hloov ntawm lub tshuab hluav taws xob yog ib qho kev qhia ncaj qha ntawm qhov kev txiav txim ntawm kev tiv thaiv hluav taws xob, qhia tias lub tshuab hluav taws xob tau raug txiav tawm ntawm qhov system.

2. Tripping ntawm excitation system hloov:

- Lub tripping ntawm lub excitation system hloov feem ntau tshwm sim nrog rau tripping ntawm lub ntsiab hloov ntawm lub tshuab hluav taws xob, uas qhia tau hais tias lub tshuab hluav taws xob tau poob qhov zoo siab tam sim no thiab tsis tuaj yeem ua haujlwm li qub.

3. Cov lus qhia txawv txav ntawm cov ntsuas:

- Cov lus qhia ntawm cov ntsuas xws li cov stator tam sim no, lub zog ua haujlwm thiab rov ua haujlwm, qhov hluav taws xob, thiab zaus ntawm lub tshuab hluav taws xob yuav poob mus rau xoom lossis ze rau xoom.

4. Kev tiv thaiv lub tswb:

- Cov cuab yeej tiv thaiv hluav taws xob yuav xa tawm cov suab sib raug zoo thiab pom lub tswb ceeb toom los qhia hom thiab qhov chaw ntawm kev tiv thaiv.

5. Cov tsos mob sab nraud:

- Tej zaum yuav muaj cov tsos mob sab nraud xws li cuam tshuam rau lub cev, lub suab tsis zoo ntawm lub tshuab hluav taws xob, kev vibration ntxiv, haus luam yeeb, lossis hluav taws.

III. Txoj kev tuav

1. Tshawb xyuas thiab lees paub qhov xwm txheej tripping:

- Tam sim ntawd xyuas seb tag nrho cov meters ntawm lub tshuab hluav taws xob tau rov qab mus rau xoom, thiab seb qhov hloov pauv loj thiab qhov hloov pauv ntawm lub tshuab hluav taws xob puas tau ploj mus, thiab paub meej tias lub tshuab hluav taws xob tau raug cuam tshuam zoo.

2. Restore lub hwj huam mov ntawm qhov chaw nres tsheb kev pab cuam system:

- Tshawb xyuas seb qhov kev hloov pauv ceev ntawm lub chaw nres tsheb qhov kev pabcuam puas tau ua tiav. Yog tias nws tsis tau ua haujlwm lossis poob qis tom qab ua haujlwm, sim kaw nws lub zog ib zaug. Yog tias qhov yuam kev kaw tsis tiav, tsis txhob sim kaw nws dua, thiab tam sim ntawd ua kev ntsuas los kho lub zog ntawm qhov chaw nres tsheb kev pabcuam.

3. Tshawb xyuas thiab daws qhov txhaum:

- Raws li qhov ua rau muaj kev tsis sib haum xeeb thiab qhov xwm txheej ntawm qhov chaw, xyuas thiab ntsuas lub tshuab hluav taws xob thiab lub tshuab hluav taws xob-transformer system los txiav txim qhov xwm txheej thiab qhov ua txhaum. - Siv cov kev ntsuas coj los sib xws, xws li cais qhov chaw txhaum, rov ua kom lub rwb thaiv tsev, hloov cov khoom puas, thiab lwm yam.

4. Rov qab ua haujlwm ntawm cov khoom siv:

- Tom qab paub meej tias qhov txhaum tau raug tshem tawm thiab lub kaw lus ruaj khov, maj mam rov ua haujlwm ntawm lub tshuab hluav taws xob. Ua tib zoo saib xyuas cov xwm txheej ntawm kev ua haujlwm ntawm qhov excitation system, kev tswj ceev ceev, thiab lwm yam, kom ntseeg tau tias lub tshuab hluav taws xob ruaj khov.
