Hloov txoj hauv kev rau Capacitor Reactive Power Compensation

Txoj kev hloov pauv rau capacitor reactive fais fab nyiaj them yog lub tshuab tseem ceeb uas txiav txim siab cov txiaj ntsig zoo, khoom siv lub neej, thiab daim phiaj hluav taws xob zoo. Lub hom phiaj tseem ceeb yog hloov cov tsev txhab nyiaj capacitor rau lossis tawm sai, raug, thiab ua kom zoo raws li cov kev hloov pauv hauv cov khoom siv hluav taws xob reactive, tsis txhob "dhau- nyiaj pab" lossis "hauv- nyiaj them poob haujlwm."

 

Cov hauv qab no yog cov kev hloov pauv tseem ceeb thiab lawv cov ncauj lus sib piv:

1. Kev faib tawm raws li Txoj Cai Tswjfwm

(1) Voltage -Raws li Hloov

● Txoj Cai: Saib xyuas qhov hluav taws xob busbar. Cov capacitors tau hloov mus rau kauj ruam -los ntawm - kauj ruam thaum qhov hluav taws xob poob qis dua qhov kev txwv qis dua thiab hloov tawm cov kauj ruam - los ntawm - kauj ruam thaum nws tshaj li qhov kev txwv siab tshaj.

● Qhov Zoo: Kev tswj yooj yim, tus nqi qis.

● Qhov tsis zoo: Indirect reactive zog tswj. Nws tuaj yeem ua rau muaj kev ua haujlwm tsis zoo- xws li hloov pauv ntawm cov khoom siv hluav taws xob thaum lub teeb pom kev zoo thiab qhov kev thov rov ua haujlwm tsis zoo tab sis qhov hluav taws xob tsawg (tom kawg ntawm kab ntev), ua rau dhau - cov nyiaj them poob haujlwm thiab qhov hluav taws xob ntau dua, thiab rov ua dua. Haum rau cov xwm txheej uas theem voltage yog thawj qhov kev txhawj xeeb.
