Cov laj thawj yog vim li ntawd ib sab thib ob ntawm cov kev hloov pauv tam sim no yuav tsum tau ua kom tsis zoo thiab kev nyab xeeb kev nyab xeeb los ntawm tsis yog av nws tau txheeb xyuas raws li hauv qab no:
Vim li cas rau kev ua si
Kev tiv thaiv kev nyab xeeb: Thaum tus hloov pauv tam sim no ua haujlwm hauv lub zog hluav taws xob siab, nws sab thawj sab yog nthuav tawm rau cov hluav taws xob ntau. Yog tias cov rwb thaiv tsev nruab nrab ntawm thawj lub zog thiab theem nrab windings tsis tau, yuav nkag mus rau sab nraud, uas yog kev nyab xeeb rau kev nyab xeeb ntawm cov neeg ua haujlwm thiab khoom siv. Los ntawm grounding sab nraud, thaum muaj hluav taws xob ntau ntxiv rau hauv lub ntiaj teb kev phom sij rau lub ntiaj teb, yog li tiv thaiv hluav taws xob rau cov cuab yeej hluav taws xob thiab cov ua haujlwm.
Lub peev xwm ruaj khov: Kev ua hauv av ruaj khov lub peev xwm ntawm cov kev pheej hmoo ntawm cov hluav taws xob thiab txo qhov kev pheej hmoo ntawm kev ntsuas yuam kev lossis khoom siv puas tsuaj los ntawm kev ua kom ntab. Tom qab ib sab theem nrab yog grounded, nws muaj peev xwm txhim khu kev qha ntawm lub xeev muaj peev xwm ncua sijhawm, uas muaj txiaj ntsig zoo rau kev ntsuas kev ntsuas.
Tiv thaiv kev tiv thaiv ntau ntawm cov hluav taws xob ntawm cov neeg raug mob: Ib qho hloov pauv tam sim no yog sib npaug rau cov kauj ruam hloov tshiab. Grounding sab nraud sab feem ntau tiv thaiv kev loj hluav taws xob tsim tawm thaum sab ob yog qhib-ncig. Thaum ib sab sab ob yog qhib vim qhov txhaum, muaj ultra-siab voltage yog tsim nyob rau hauv kauj, uas tej zaum yuav tsoo lub rwb thaiv tsev thiab ua rau muaj hluav taws xob hluav taws xob. Yog hais tias lub coil theem theem siab tau ua rau hauv lub ntiaj teb, khaws cov kauj theem nrab ntawm cov peev txheej hauv av thiab yog li ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab khoom siv.
Kev Nyab Xeeb Kev Nyab Xeeb ntawm Ungrounded Sab
Kev pheej hmoo ntawm hluav taws xob poob siab: Yog hais tias sab thib ob ntawm tus hloov pauv tam sim no tsis yog av, thaum lub rwb thaiv tsev ntawm thawj lub winding so, siab voltage yuav txuas rau qhov tsawg-voltage sab. Nyob rau lub sijhawm no, yog tias ib tus neeg kov cov khoom sab nraud lossis kab, lawv yuav raug hluav taws xob, ua rau hluav taws xob hlawv lossis tuag taus.
Cuab Yeej Siv Khoom Puas: Kev ntsuas siab heev nkag mus rau sab ob tsis yog ua rau cov neeg ua haujlwm tab sis kuj ua rau cov khoom siv thib ob xws li ammeters, cov hwj huam metres, thiab relay tiv thaiv cov khoom siv. Kev puas tsuaj rau cov khoom siv no cuam tshuam rau kev ua haujlwm ib txwm muaj thiab saib xyuas ntawm lub zog hluav taws xob thiab tej zaum yuav ua rau muaj kev ua tsis tiav.
Electric Zog Metering Yuam Kev: Txawm hais tias ib qho kev hloov pauv tam sim no tsis cuam tshuam ncaj qha rau lub ntsuas kev ntsuas, qhov tsis muaj kev cuam tshuam ntxiv rau hauv cov kab ke. Cov neeg cuam tshuam no cuam tshuam qhov tseeb ntawm hluav taws xob hluav taws xob thiab ua rau tsis muaj peev xwm thiab nqa cov tuam txhab hluav taws xob thiab cov neeg siv.
Kev ua ke ntawm kev tiv thaiv ntaus ntawv: Tus hloov pauv tam sim no yog qhov tseem ceeb ntawm kev tiv thaiv hluav taws xob. Yog tias ib sab theem ob tsis yog av, nws yuav tsim cov cuab yeej tiv thaiv relay tiv thaiv los yog ua tsis tau haujlwm. Piv txwv li, thaum muaj kev txhaum, cov khoom tiv thaiv tsis tuaj yeem txheeb xyuas qhov ua txhaum lossis cuam tshuam rau kev ua haujlwm ruaj khov ntawm lub zog hluav taws xob.
Kev pheej hmoo ntawm voltage transformer puas: Hauv ib qho chaw nkaum, kev siv tsis raug ntawm cov hloov pauv tam sim no tuaj yeem ua rau hlawv cov hluav taws xob hluav taws xob (PT). Qhov no yog tshwj xeeb tshaj yog nyob rau hauv 10KV -35 kv ungrounds. Kev puas tsuaj rau lub voltage transformer tsis tsuas yog cuam tshuam rau kev ntsuas raug ntawm lub zog hluav taws xob tab sis kuj tseem tuaj yeem ua rau kev tiv thaiv kev tiv thaiv thiab cov khoom siv tsis siv neeg.
Kev pheej hmoo ntawm ferromagnetic resonance: Hauv qee kis, cov chaw nyob muaj hnub muaj ntau dua rau kev rov qab ua kom zoo nkauj. Ferromagnetic resonance tej zaum yuav ua rau thawj lub tshuab hluav taws xob ntawm cov hluav taws xob hluav taws xob hloov rau hlawv, hem kev nyab xeeb ntawm lub zog ntawm lub zog.
