Cov tshuaj tiv thaiv hluav taws xob muaj peev xwm capacitor tau disconnected

Hauv kev tsim qauv thiab kev saib xyuas ntawm reactive fais fab nyiaj pab kiag hauv cov hluav taws xob reactive capactration yog qhov teeb meem kev sib tw tseem ceeb. Tom ntej no, peb yuav ua qhov teeb meem kev tshaj lij ntawm qhov teeb meem tshwj xeeb uas siv tau cov neeg siv cua siv tau xaiv cov twj siv hluav taws xob.

I. Kev Txwv ntawm Circuit Court Lub Nkoj Hauv Kev Siv Hluav Taws Xob Hluav Taws Xob

Kev siv ncaj qha ntawm cov huab cua zoo tib yam rau cov hluav taws xob hluav taws xob muaj peev xwm muaj kev phom sij. Thaum lub capacitors txuas nrog lub Hwj Chim Grid, ib qho tripping ntws tam sim no txog li 20 {- 30 lub sij hawm Rated tam sim no yuav tsim tawm. Qhov kev hloov pauv tam sim no yuav ua rau muaj kev txiav tawm ntawm lub tshuab siv hluav taws xob. Kev ntsuas tiag tiag qhia tau tias thaum lub peev xwm lub twj tau hloov mus thiab tawm, lub chaw sib ze ntawm cov cua hloov pauv ntawm cov cua dub yog 5-8 zaug sai dua li siv tas li. Ntxiv mus, thaum cov hluav taws xob reactive hluav taws xob muaj peev xwm tau ua kom tsis sib xws yuav tshwm sim, nrog tus nqi siab ntawm 3-5 zaug ntawm lub cev voltage. Cov chaw no tsis tshua muaj neeg xav tau ntawm lub arc extinguishing muaj peev xwm ntawm huab cua hloov.

Ii. Kev ua haujlwm zoo ntawm cov khoom siv tshwj xeeb hloov

Cov kev tshaj lij Resterive Poweration Capacation Capacitor hloov cov khoom siv adves tshwj xeeb los daws cov kev cov nyom tshwj xeeb no. Thyristian hloov cov khoom siv (TSC) tuaj yeem ua tiav xoom {{}} hla kev hloov pauv, tswj tau cov hauv nruab nrab tam sim no tsis pub dhau 1.5 zaug. Lub composite hloov ua ke cov txiaj ntsig zoo ntawm cov neeg ua kom haum thiab koj ntseeg tau tam sim no ntws thaum ua tiav xoom- inrush switching. Lub sib nqus uas sib nqus cov neeg ua kom tau lub xeev sib cuag los ntawm lub neej muaj zog tas mus li, nrog lub sijhawm ua haujlwm ntawm 1-20,000 lub neej ua haujlwm ntawm cov neeg sib tsoo hauv hluav taws xob. Cov khoom tshwj xeeb no yog txhua yam nruab nrog kev tiv thaiv kev tiv thaiv kev ua haujlwm, uas tuaj yeem ua haujlwm zoo rau kev ua haujlwm ua haujlwm.

III. Xaiv cov lus qhia rau cov xwm txheej sib txawv

For different application scenarios, the selection of the switching device for reactive power compensation capacitors should be different: For fixed compensation power distribution systems, a combination of contactors and current-limiting reactors can be adopted; Rau Dynamic them nqi xwm txheej uas yuav tsum tau hloov ntau zaus, TSC lossis cov keyboard lossis composite compitored tau pom zoo; Hauv qhov qis - voltage thiab me me} {}}} peg- pensging resistors) kuj tseem siv tau lwm txoj. Txawm li cas los xij, nyob rau hauv txhua rooj plaub, cov kev sib txuas sib npaug ntawm Circuit Court yuav tsum tsis txhob siv los ua lub ntsiab hloov ntaus ntawv rau cov hluav taws xob kev them nyiaj kho vaj huam.

Nrog kev nce qib ntawm cov phiaj xwm kev tsim kho ntse tsim kho, hloov tshuab ntawm cov hluav taws xob rov qab muaj zog muaj peev xwm. Xaiv cov cuab yeej tsim nyog hloov tsis tuaj yeem tsuas yog muaj kev nyab xeeb ntawm cov cuab yeej siv ntawm lub zog hluav taws xob muaj peev xwm siv tau. Thaum lub sij hawm tsim thiab saib xyuas ntawm cov phiaj xwm, engineers yuav tsum xaiv cov kws tshaj lij kev puas tsuaj raws li cov yam ntxwv kev nyab xeeb thiab kev ua tau zoo los ntawm kev siv cov khoom siv phom sij.
