Nyeem txog kev tiv thaiv relay hauv ib tsab xov xwm - kev tiv thaiv nyob deb

 

 

Kev tiv thaiv kev deb yog ib qho khoom siv tiv thaiv raws li kev ntsuas qhov deb. Nws qhov kev txiav txim thiab kev xaiv yog nyob ntawm qhov ntsuas qhov ntsuas hauv cheeb tsam (impedance, reactance, kev taw qhia) thiab cov txheej txheem ntawm qhov kev tiv thaiv ntawm cov txiaj ntsig sib piv, thiab impedance, reactance, thiab qhov ntev ntawm cov kab sib kis yog proportional rau qhov deb, yog li nws hu ua kev tiv thaiv nyob deb.
 

 

Kev tiv thaiv kev deb yog siv rau cov kab sib kis. Cov ntaub ntawv sib txawv, nws tau muab faib ua theem-rau-theem kev tiv thaiv thiab kev tiv thaiv hauv av. Feem ntau, nws yog hom peb ntu lossis plaub ntu. Thawj ob ntu nrog kev taw qhia, yog lub ntsiab tiv thaiv kab. Thawj ntu tiv thaiv 80% txog 90% ntawm tag nrho cov kab ntev, thiab ntu thib ob tiv thaiv qhov seem 10% mus rau 20% thiab ua haujlwm tiv thaiv kev tiv thaiv rau cov tsheb npav nyob sib ze. Tshooj thib peb yog nrog lossis tsis muaj kev taw qhia, thiab qee qhov kuj muaj ntu plaub yam tsis muaj kev taw qhia, raws li cov kab thiab cov kab nyob sib ze tiv thaiv.

 

Kev ntsuam xyuas kev tiv thaiv relay tsis tu ncua pab txhawm rau txuas lub neej kev pab cuam ntawm lub zog hluav taws xob thiab tseem ceeb heev rau kev nyab xeeb ntawm hluav taws xob, peb xav kom pebRDJB-1600M, nyem rau ntawm tus qauv naj npawb kom paub ntau ntxiv txog cov tsis muaj thiab cov ntsiab lus ntawm cov khoom.

Rau cov cuab yeej tiv thaiv kev deb kom ua haujlwm kom raug thiab ntseeg tau, kev tiv thaiv kev deb yuav tsum ua raws li cov cai hauv qab no.
 

1) Nyob rau hauv qhov kev tshwm sim ntawm ib tug luv luv-circuit nyob rau hauv txoj kab yuav tiv thaiv, ntsuas impedance ntawm impedance relay siv los ntsuas lub ntsiab yuav tsum proportional rau qhov kev ncua deb ntawm kev tiv thaiv installation thiab luv luv-circuit point.

 

2) Nws yuav tsum tsis txhob override qhov kev txiav txim nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv-circuit sab nraum qhov zoo taw qhia cheeb tsam

 

3) Yuav tsum muaj kev taw qhia meej. Tsis muaj qhov chaw tuag nyob rau hauv qhov zoo ntawm qhov hluav taws xob qhov hluav taws xob luv luv Circuit Court, qhov opposite direction luv luv Circuit Court yuav tsum tsis txhob yog ib tug cuav kev txiav txim.

 

4) Kev tiv thaiv hauv av nyob rau hauv cheeb tsam los ntawm kev hloov pauv loj nyob rau hauv luv luv Circuit Court yuav tsum muaj peev xwm ua tau, uas yog, muaj peev xwm los teb rau qhov kev hloov pauv loj.
 

5) Qhov tsawg kawg nkaus load impedance tsis ua haujlwm tsis raug.
 

6) Lub kaw lus yuav tsum tsis txhob ua haujlwm tsis ua haujlwm thaum oscillation tshwm sim.
 

7) TV thib ob Circuit Court disconnection yuav tsum tsis txhob malfunction.

 

 

 

 

Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm kev tiv thaiv kev deb, kev tiv thaiv kev deb feem ntau yog tsim los ntawm tsib ntu: qhov ntsuas qhov, qhov pib, qhov logic, oscillation blocking part, thiab voltage poob thaiv qhov.

 

Lub luag haujlwm ntawm qhov ntsuas qhov ntsuas: yog ntsuas qhov kev ncua deb mus rau qhov luv-circuit point thiab txiav txim siab qhov kev taw qhia ntawm qhov luv-circuit txhaum.
 

Lub luag haujlwm ntawm qhov pib: yog txhawm rau txiav txim siab seb lub kaw lus puas nyob hauv lub xeev txhaum, thaum qhov kev ua txhaum luv luv tshwm sim, pib tam sim ntawm cov khoom tiv thaiv.
 

Lub luag haujlwm ntawm lub logic ib feem: yog kom paub txog kev ua haujlwm ntawm cov cuab yeej tiv thaiv thiab tsim lub sijhawm txwv rau txhua ntu ntawm kev tiv thaiv.
 

Oscillation thaiv ib feem ntawm lub luag haujlwm: txhawm rau tiv thaiv lub kaw lus los ntawm kev oscillating thaum siv cov cuab yeej tiv thaiv yuam kev
 

Kev poob ntawm qhov hluav taws xob thaiv ib feem ntawm lub luag haujlwm: txhawm rau tiv thaiv lub TV thib ob Circuit Court disconnection thiab poob ntawm qhov hluav taws xob thaum lub impedance relay kev txiav txim yog tshwm sim los ntawm kev tiv thaiv kev ua txhaum.
