Qhov txawv ntawm Dynamic Compensation thiab Static Compensation
Jan 08, 2026| Lub luag haujlwm tseem ceeb ntawm kev them nyiaj rov qab siv hluav taws xob yog txhawm rau txhim kho cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob, yog li txo cov khoom siv hluav taws xob thiab hluav taws xob poob, stabilizing qhov hluav taws xob, thiab txhim kho cov khoom siv hluav taws xob zoo. Nws kuj ua rau kom muaj kev ruaj ntseg thiab muaj peev xwm nyob rau hauv ntev - kis tau tus mob nyob deb, thiab sib npaug lub zog nquag thiab reactive ntawm peb -theem loads. Yog li, xaiv cov khoom siv hluav taws xob tsim nyog tau txais txiaj ntsig zoo tuaj yeem txo cov khoom siv hluav taws xob poob thiab txhim kho daim phiaj zoo. Hloov pauv, kev xaiv tsis raug yuav ua rau muaj qhov hloov pauv voltage, nce kev sib haum xeeb, thiab lwm yam teeb meem.
Static Compensation thiab nws qhov zoo
Kev them nyiaj zoo li qub yog hais txog kev them nyiaj uas cov capacitors tsis hloov pauv hauv lub sijhawm tiag - raws li qhov hloov pauv ntawm lub zog reactive. Hloov chaw, kev hloov pauv yog txhob txwm ncua, feem ntau ntau dua 40 vib nas this. Raws li cov khoom siv hluav taws xob txuas nrog lossis txiav tawm, lub zog reactive xav tau los ntawm daim phiaj hloov raws li. Txhawm rau kom tsis txhob muaj kev hloov pauv ntau zaus, uas tuaj yeem ua rau cov khoom hloov pauv thiab cov capacitors raug cuam tshuam rau ntau dhau, kev txiav txim siab qeeb yog siv. Capacitors tsuas yog hloov mus rau thaum lub zog ntawm cov khoom siv hluav taws xob nyob ruaj khov hauv qab tus nqi uas tau teev tseg. Conversely, yog hais tias lub hwj chim yam tseem ceeb tshaj ib tug tej yam nqi los yog reactive hwj chim rov qab mus rau hauv daim phiaj, capacitors yog switched tawm tom qab ib tug ncua, yog hais tias tus mob nyob twj ywm.
Kev them nyiaj zoo li qub tsis cuam tshuam rau qhov nruab nrab lub zog ntawm tus neeg siv khoom nyob rau lub sijhawm, thiab tsis cuam tshuam rau kev them nqi ntawm cov tuam txhab muab hluav taws xob. Ntawm qhov tsis sib xws, los ntawm kev zam kev hloov pauv tsis tu ncua, nws txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv hloov pauv thiab cov nyiaj them poob haujlwm capacitors. Tsis tas li ntawd, txij li kev hloov pauv tsis tau ua tiav hauv lub sijhawm tiag tiag- raws li kev hloov pauv ntawm lub zog reactive, contactors txaus raws li cov khoom siv hloov pauv, txo tus nqi ntawm cov khoom siv them nyiaj thiab kev saib xyuas yooj yim.
Vim cov txiaj ntsig zoo li no, cov cuab yeej siv nyiaj zoo li qub tau ua haujlwm yuav luag thoob ntiaj teb niaj hnub no.
Dynamic Compensation thiab nws qhov zoo
Dynamic nyiaj them muaj xws li hloov cov capacitors hauv lub sijhawm tiag tiag -, ua raws li cov kev hloov pauv hauv lub zog reactive. Txhawm rau ua tiav qhov no tiag tiag - sijhawm taug qab, tag nrho cov txheej txheem - los ntawm kev kuaj pom lub teeb liab mus rau kev hloov pauv ntawm lub capacitor - yuav tsum ua kom tiav hauv 10 mus rau 20 milliseconds. Cov khoom siv hluav taws xob tsis tuaj yeem ua tau raws li qhov yuav tsum tau hloov pauv sai, txawm tias qhov ceev tshaj plaws yuav siv sijhawm tsawg kawg 0.2 vib nas this. Yog li ntawd, kev tshawb nrhiav hluav taws xob thiab thyristor{10}}raws li kev hloov pauv tau siv los ua kom tau raws li qhov xav tau kom paub sai thiab hloov pauv.
Dynamic capacitor them nyiaj tsis yog lub tshuab tshiab; nws tau ntev tau siv nyob rau hauv hluav taws xob arc steelmaking furnaces. Thaum lub sij hawm melting txheej txheem ntawm ib tug arc rauv, luv tes hauj lwm tshwm sim intermittently, thiab cov tshwm sim surge tam sim no ua rau hnyav voltage hloov nyob rau hauv lub mov busbar, adversely cuam tshuam rau lwm tus neeg siv. Hom kev hloov pauv tam sim no tam sim no hu ua "voltage flicker" lossis "power flicker." Txhawm rau txo cov teebmeem tsis zoo no thiab txhim kho qhov zoo ntawm lub zog hluav taws xob, kev them nyiaj tam sim no nrog cov capacitors tau qhia. Lub zog reactive xav tau los ntawm arc rauv yog muab tam sim ntawd hauv zos los ntawm cov capacitors, tshem tawm qhov xav tau ntev - kis tau tus mob ntawm kab sib chaws. Qhov no txo qhov voltage flicker ntawm cov busbar uas muab cov arc rauv, yog li kev txhim kho cov khoom siv hluav taws xob zoo.
