Preface: Hauv peb lub neej txhua hnub thiab cov txheej txheem tsim khoom, qhov tsis sib npaug ntawm peb theem load feem ntau tshwm sim.Qhov teeb meem ntawm kev siv hluav taws xob ib txwm yog lub teb chaws txoj kev saib xyuas, yog li peb yuav tsum nkag siab txog lub hauv paus ntsiab lus ntawm qhov tshwm sim ntawm peb-theem imbalance.Nkag siab txog kev phom sij thiab kev daws teeb meem ntawm peb theem tsis sib npaug.
Lub hauv paus ntsiab lus ntawm peb-theem unbalance yog hais tias lub amplitudes ntawm peb-theem tam sim no los yog voltage nyob rau hauv lub hwj chim system yog inconsistent.Qhov amplitude sib txawv tshaj li qhov tau teev tseg.Qhov tsis sib xws load faib ntawm txhua theem, qhov tsis sib xws ntawm unidirectional load zog noj thiab kev nkag mus ntawm ib-theem high-power load yog lub ntsiab yog vim li cas rau peb-theem imbalance.Nws kuj suav nrog qhov tsis txaus ntawm kev tsim kho hluav taws xob, kev hloov pauv thiab kev ua haujlwm thiab kev saib xyuas, uas yog vim li cas lub hom phiaj.Txhawm rau muab piv txwv yooj yim tshaj plaws, hauv lub neej niaj hnub, feem ntau cov khoom siv hauv tsev thiab cov khoom siv teeb pom kev zoo yog cov khoom siv ib zaug.Vim muaj coob tus thiab sib txawv lub sijhawm ua kom muaj zog, qhov voltage ntawm qee cov neeg siv yuav qis, ua rau qee cov khoom siv hluav taws xob ua haujlwm tsis zoo.Qhov hluav taws xob siab ntawm qee cov neeg siv yuav ua rau muaj kev phom sij loj dua rau kev laus ntawm circuits thiab insulators.Cov no tuaj yeem suav tau raws li qhov kev puas tsuaj tshwm sim los ntawm peb-theem imbalance.
Qhov teeb meem tshwm sim los ntawm peb-theem imbalance yog thawj zaug ua rau muaj kev puas tsuaj rau lub transformer.Vim yog qhov tsis sib npaug ntawm peb-theem load, lub transformer ua haujlwm nyob rau hauv lub xeev asymmetric, ua rau muaj kev nce hauv qhov poob ntawm lub zog hluav taws xob, uas suav nrog tsis muaj kev thauj khoom thiab kev thauj khoom poob.Lub transformer khiav nyob rau hauv lub unbalanced lub xeev ntawm peb-theem load, uas yuav ua rau ntau tshaj tam sim no.Qhov kub ntawm qhov chaw hlau hauv zos nce ntxiv, thiab txawm tias ua rau kev puas tsuaj ntawm cov transformer.Hauv particular, tooj liab poob ntawm lub transformer yog nce, uas tsis tsuas yog txo cov zis zoo ntawm hluav taws xob lub zog, tab sis kuj yooj yim ua rau qhov ntsuas tsis raug ntawm hluav taws xob.
Ntxiv nrog rau qhov kev puas tsuaj rau lub transformer, nws muaj kev cuam tshuam rau lwm yam khoom siv hluav taws xob, vim tias qhov tsis sib xws ntawm peb-theem voltage yuav ua rau qhov tsis txaus ntawm qhov tam sim no, uas yuav ua rau kom kub ntawm lub cev muaj zog, nce lub zog noj, thiab tsim kev co.Kev pabcuam lub neej ntawm cov khoom siv hluav taws xob tau txo qis heev, thiab cov nqi kho thiab kho cov khoom siv niaj hnub tau nce ntxiv.Tshwj xeeb tshaj yog nyob rau hauv cov kev tshwm sim ntawm overload thiab luv luv Circuit Court, nws yog yooj yim dua ua rau lwm yam poob (xws li hluav taws).Nyob rau tib lub sij hawm, raws li qhov voltage thiab tam sim no imbalances nce, qhov no kuj ua rau cov kab poob ntawm Circuit Court.
Tau ntsib nrog peb-theem tsis sib xws uas tau tsim ntau yam kev puas tsuaj rau peb, peb yuav ua li cas los daws cov teeb meem?Thawj qhov yuav tsum yog kev tsim kho ntawm daim phiaj hluav taws xob.Thaum pib ntawm kev tsim daim phiaj hluav taws xob, nws yuav tsum koom tes nrog tsoomfwv cov chaw haujlwm kom ua tiav kev npaj tsim hluav taws xob tsim nyog.Siv zog los daws qhov teeb meem ntawm peb-theem imbalance ntawm lub hauv paus ntawm qhov teeb meem kev loj hlob.Piv txwv li, kev tsim kho ntawm lub zog faib hluav taws xob yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "kev muaj peev xwm me me, ntau lub ntsiab lus xa tawm, thiab lub vojvoog luv luv" rau qhov chaw xaiv ntawm cov khoom xa tawm.Ua ib txoj hauj lwm zoo ntawm qhov tsawg-voltage meter installation, thiaj li hais tias kev faib ntawm peb theem yog uniform li sai tau, thiab zam qhov tshwm sim ntawm load theem deviation.
Nyob rau tib lub sij hawm, vim hais tias peb-theem imbalance yuav ua rau tam sim no tshwm nyob rau hauv nruab nrab kab.Yog li ntawd, multi-point grounding ntawm cov kab nruab nrab yuav tsum tau txais kev pom zoo kom txo tau lub zog poob ntawm cov kab nruab nrab.Thiab tus nqi tsis kam ntawm cov kab nruab nrab yuav tsum tsis txhob loj dhau, thiab tus nqi kuj tseem loj heev, uas yuav yooj yim ua rau cov kab poob.
Thaum peb nkag siab lub hauv paus ntsiab lus ntawm peb-theem imbalance, nws raug mob thiab yuav ua li cas nrog nws, peb yuav tsum sib zog ua kom peb-theem sib npaug.Thaum tam sim no dhau los ntawm cov kab xaim hauv lub zog hluav taws xob, vim tias cov kab hluav taws xob nws tus kheej muaj tus nqi tsis kam, nws yuav ua rau lub zog poob rau cov khoom siv hluav taws xob.Yog li ntawd, thaum peb-theem tam sim no tsim nyob rau hauv qhov sib npaug, lub hwj chim poob tus nqi ntawm cov khoom siv hluav taws xob yog qhov qis tshaj.
Peb-theem tsis sib npaug tswj cov cuab yeej tsim los ntawm Hongyan Electric tuaj yeem tswj tau cov teeb meem ntawm peb-theem tsis sib npaug, tsis tshua muaj hluav taws xob davhlau ya nyob twg, thiab kev them nyiaj bidirectional ntawm reactive tam sim no hauv kev hloov pauv thiab kho dua tshiab ntawm kev faib tawm.
