Sib nqus tswj reactors

MCR yog dab tsi?

Sib nqus tswj reactors (MCR) yog ib hom shunt reactor nrog adjustable muaj peev xwm, uas yog tsuas yog siv rau reactive zog them nyiaj ntawm lub hwj chim system.

MCR muaj cov hlau nplaum sib nqus los tswj cov permeability ntawm reactor core, uas saturates tag nrho cov tub ntxhais hlau thiab txhim kho cov kev ua tau zoo heev los ntawm kev hloov cov qauv ntawm cov magnetic furnace raws li ib txwm sib nqus saturation thiab reactor. yog li kom du qhov zoo inductance ntawm electrodeless regulator. Schematic daim duab yog raws li nram no:

MCR ua haujlwm li cas

MCR yog raws li lub hauv paus ntsiab lus ntawm DC magnetization, siv qhov ntxiv DC excitation magnetization reactor core, los ntawm kev kho qhov sib nqus saturation degree ntawm cov tub ntxhais ntawm MCR, hloov cov permeability ntawm cov tub ntxhais, kom ua tiav qhov nruam adjustable reactance tus nqi. Lub shunt sib nqus Circuit Court yog tsim los ntawm cov tub ntxhais nyob rau hauv cheeb tsam unsaturated thiab cov tub ntxhais nyob rau hauv lub saturated cheeb tsam teem alternately nyob rau hauv lub tub ntxhais ntawm lub reactor; lub excitation magnetization ntawm cov tub ntxhais los ntawm qhov ntxiv DC excitation tam sim no yog tswj los ntawm kev kho lub thyristor triggering conduction lub kaum sab xis; lub magnetization degree thiab saturation cheeb tsam ntawm cov tub ntxhais nyob rau hauv lub unsaturated cheeb tsam thiab saturation cheeb tsam yog hloov los ntawm kev kho cov cheeb tsam los yog lub magnetic tsis kam ntawm cov tub ntxhais nyob rau hauv lub unsaturated cheeb tsam thiab lub saturation cheeb tsam nyob rau hauv lub shunt magnetic Circuit Court. core tuaj yeem paub qhov kev hloov pauv nrawm thiab nrawm ntawm tus nqi reactance ntawm 1% txog 100%. Ua ke nrog capacitor, nws tuaj yeem muab qhov zoo thiab qhov tsis zoo tsis tu ncua adjustable reactive zog, yog li nws tuaj yeem tswj qhov system voltage thiab reactive zog ntau dua thiab sai dua. Vim tias tsis muaj lossis tsis tshua muaj kev cuam tshuam thiab cuam tshuam los ntawm kev hloov pauv capacitor, kev ntseeg siab thiab kev pabcuam lub neej ntawm cov cuab yeej tuaj yeem txhim kho tau zoo. Nws tuaj yeem them nyiaj rau peb theem sib cais, tshwj xeeb tshaj yog nyob rau hauv rooj plaub ntawm peb-theem fais fab tsis txaus.

Lub luag haujlwm ntawm MCR yog dab tsi

1. Ua kom lub zog muaj zog thiab txo cov kab poob los ntawm lub zog reactive, txhim kho lub zog zoo ntawm cov neeg siv.cov khoom siv hluav taws xob tuaj yeem ncav cuag qhov xav tau ntawm 0.90-0.99.

2. Tshem tawm thiab lim cov kev sib haum xeeb, txo qhov kev hloov pauv ntawm qhov hluav taws xob, flicker, distortion thiab stabilizing voltage, txhim kho lub neej kev pab cuam ntawm transformers, cov kab sib kis thiab lwm yam khoom siv hluav taws xob.

3.Raws li reactive fais fab nyiaj them, MCR tuaj yeem kho cov zis reactive zog smoothly, uas muaj ntau lub zog dua li cov khoom siv hluav taws xob reactive.

4. Txo qhov cuam tshuam ntawm lub zog hluav taws xob hauv zos xws li asynchronous lub cev muaj zog pib, hluav taws xob arc rauv ua haujlwm thiab txhim kho kev ruaj ntseg, tshwj xeeb tshaj yog rau cov tsis muaj zog tam sim no.

Qhov zoo ntawm MCR yog dab tsi

1.tsis muaj qhov ua haujlwm sab hauv, uas yuav tsis cuam tshuam rau lub cev;

2.Txoj kev tswj tsis tu ncua tuaj yeem paub qhov nyiaj tau los ntawm lub zog reactive;

3.Kev ua haujlwm ruaj ntseg, txij nkawm dawb thiab tsis muaj neeg saib xyuas;

4. Tsawg poob (tus kheej poob

5. Tsawg zog poob;

6.Small harmonic (tsawg dua 50% ntawm cov khoom zoo sib xws);

7.Reliable zoo, ntev khoom lub neej (ntau tshaj 25 xyoo);

8.Kev yooj yim installation thiab me me hauv pem teb;

9. Muaj peev xwm overload, tuaj yeem tshaj 150% hauv lub sijhawm luv luv;

10.No electromagnetic cuam tshuam thiab ib puag ncig muaj kuab paug.

Qhov chaw twg siv MCR

Hluav taws xob railway

Lub load ntawm lub electrified railway traction substation yog ib ntus. Thaum hluav taws xob locomotive hla, lub load mam li nco dheev tshwm. Tom qab lub tsheb ciav hlau hla, lub load ploj. Kev siv ib txwm hloov pauv capacitor yuav ua rau lub traction substation hloov ntau pua zaus txhua hnub. Kev nqis tes ua, uas ua rau lub neej ua haujlwm luv luv ntawm cov khoom siv hluav taws xob, thiab qhov asymmetry ntawm txoj kev tsheb ciav hlau hluav taws xob ua rau nws qhov kev cuam tshuam tsis zoo yuav ua rau hnyav heev.

Coal thiab Tshuaj

Muaj ntau qhov cuam tshuam tsis sib xws xws li hoists hauv cov chaw lag luam thee, uas tsis tsuas yog muaj qhov hloov pauv loj ntawm lub zog hluav taws xob tab sis kuj muaj kev sib haum xeeb loj, uas yooj yim ua rau cov khoom siv hluav taws xob puas tsuaj thiab cuam tshuam rau lub neej kev pab cuam ntawm cov khoom siv hluav taws xob.

metallurgy

Lub load ntawm dov zeb thiab hluav taws xob arc rauv nyob rau hauv metallurgical system yog ib hom tshwj xeeb load. Nws tuaj yeem hloov cov khoom thauj los ntawm tus nqi me me mus rau tus nqi loj heev hauv lub sijhawm luv luv (tsawg dua 1s), thiab qhov kev hloov pauv sai heev. Yog li ntawd, cov cuab yeej tso saib hauv cov lag luam no tas li viav vias ntawm kev kub ceev.

Cua ua liaj ua teb

MCR-raws li SVC cov cuab yeej siv rau kev txuas ntxiv, tsis muaj kev sib cuag, thiab kev hloov pauv hloov pauv ntawm lub zog reactive hauv cua ua liaj ua teb substations, txhim kho lub zog ntawm lub cev, kho sai sai reactive zog tso zis, thiab txhawb kev rov qab voltage.

Lub zog substation

Cov teeb meem ntawm kev siv qis capacitor thiab teeb meem kev tswj kev hloov pauv tau dav. Ib tug loj tus naj npawb ntawm VQC cov cuab yeej ntsia tau yooj yim ua rau muaj teeb meem xws li kev hloov pauv ntau zaus ntawm cov tsev txhab nyiaj capacitor thiab nquag ntawm cov khoom siv hluav taws xob tswj hluav taws xob, uas txo cov khoom siv lub neej thiab ua rau muaj kev nyab xeeb ntxiv.

Cov neeg siv khoom tshwj xeeb

Cov tuam txhab textile thiab cov duab tube manufacturers muaj cov kev xav tau siab rau qhov zoo ntawm cov khoom uas lawv tsim thiab qhov voltage zoo ntawm daim phiaj fais fab. Sudden voltage tee los yog tam sim no poob yuav ua rau cov khoom pov tseg ntau hauv lawv cov khoom. Siv MCR-hom static reactive fais fab nyiaj pab kiag li lawm tuaj yeem txhim kho nws qhov hluav taws xob zoo hauv lub sijhawm luv luv.
