Peb Thaj Meter 'Qhov Taw Qhib Cug Hlau Thiab Cov Cwj Pwm



Peb Thaj Meter Box Watt-teev 'meter' yog qhov ua tau zoo ntawm txoj kev tsis ncaj ncees: lub ntsuas hluav taws xob rov qab, tsis tig, qeeb qeeb thiab lwm yam. Raws li qhov ntsuas lub zog ntsuas hluav taws xob muaj li ntawm lub cav ntsuas hluav taws xob, kev tsim hluav taws xob, kev sib cog lus nruab nrab thiab lwm yam khoom, yog li ntawd, qhov ntsuas qhov ntsuas qhov ntsuas thiab nws kho kuj yog ntau yam kev hloov. Nws yog ib qho tseem ceeb hauv cov neeg ua haujlwm ntawm cov chaw ua hauj lwm faiv fab, uas yog ib txoj hauv kev zoo los txhim kho cov duab ntawm cov khoom siv hluav taws xob thiab txo kom tsis muaj hluav taws xob rau kev ncaj ncees, kev ncaj ncees thiab ntsuas kev tsim nyog, lub sijhawm, ntawm kev thaiv qhov tsis zoo thiab coj tau zoo tiv thaiv. Kuv tau ua ke nrog lub installation ntawm hluav taws xob thiab hluav taws xob lub zog ntsuas ntsuas mus xyuas lub lag luam ntawm kev xyaum, tham txog qhov raug teeb meem ntsuas kab thaiv thiab tiv thaiv cov kev ntsuas rau neeg saib xyuas.

Ua ntej, lub hwj chim ntsuas ntaus ntau hom thaiv tsis zoo

1, ib theem ib lub cev muaj zog hluav taws xob yuam kev

Thaum qhov ncaj qha nkag mus rau ib lub cav ntim ib theem, qhov ua yuam kev yuav yog hauv lub cav ntsuas zog thiab xoom kab ntawm txoj kab hluav taws, xoom ntawm lub zog ntsuas tom qab so hauv lub xeev, kab hluav taws thiab hauv av, Hluav taws xob yog tseem qub, vim hais tias tam sim no lub cav ntsuas tam sim no tsis muaj ziag no.

Thaum qhov hluav taws xob tawm ntawm qhov sib txuas los yog cov neeg pluag kev sib txuas los ntawm kev qhib dav hluav taws xob, Peb Theem Meter Box thaum lub ntsuas ntsuas lub hwj chim P = U (0) × Icosφ = 0, lub ntsuas 't tig tsis tau. Thaum tam sim no transformer theem pib, qhov ntsuas tam sim no tsis muaj zog tam sim no los ntawm kev ntsuas lub zog ntsuas P = U (0) × Icosφ = 0, lub ntsuas 't tig tsis tau. Zoo sib xws, tam sim no transformer theem nrab ntawm luv luv Circuit Court, vim tsis muaj tam sim no los ntawm kev sib puav tam sim no, lub metre yuav tsis tig. Thaum tam sim no transformer secondary polarity reversed, lub zog ntsuas ntsuas Fais fab P = -IIcosφ, fais fab tuag ntsuas reversal.

2, peb-theem peb-xaim tshuab ob-qhov kev ntsuas hluav taws xob tsis txuas

Thaum cov kab voltage A, B theem ntawm lub suab nrov; B, C theem voltage swap; A, C theem pib ntawm qhov qhib, ntsuas tus nqi ntawm P yog xoom, lub zog ntsuas 't tig tsis tau.

3, peb yam ntawm lub ntsuas phom tsis ncaj ncees

Thaum twg muaj kab lossis TA polarity reversed, Peb Theem Meter Box lub zog ntawm tus ntsuas theem rov qab yog qhov tsis zoo thiab qhov ntsuas lub zog ua qeeb qeeb.

Thaum muaj ob-theem tam sim no kab los yog TA polarity reversed, tus nqi ntsuas ntawm theem rov qab yog qhov tsis zoo, qhov ntsuas yog ntxig.

Thaum cov theem peb theem tam sim no los yog TA polarity reversed, lub zog ntsuas 'meter', K = -1.

Thaum lub voj tam sim no qhib, qhov ntsuas yog ntsuas qhov ob-theem zog; Ob-theem qhib Circuit Court, tsuas yog ntsuas lub zog ua haujlwm; peb-theem qhib, lub zog 'meter' nres. Zoo ib yam, Peb Thaj Meter Lub thawv tam sim no tshwm sim ib theem, theem ob theem, luv luv luv peb-phase, lub metre nrog tus nqi qub.

Thaum qhov qis-voltage peb theem plaub-xov hlau ntsuas cua ntsuas TA yog qhov tseeb, thiab cov sij hawm hluav taws xob cov kab theem pib thiab qhov tam sim no tsis phim, xws li qhov ntsuas hluav taws xob rov qab.

Nyob hauv qhov hluav taws xob muaj hluav taws xob muaj ib qho kev qhib hluav taws xob, muaj cov yam ntxwv nram qab no: ib qho hluav taws xob muaj hluav taws xob hauv vas thiv, ntsuas qhov ntsuas ob-theem; ob-phase voltage Circuit Court qhib Circuit Court, qhov ntsuas yog ntsuas lub zog, lub hwj chim ntsuas qeeb; peb-theem voltage Circuit qhib qhib Thaum lub metre nres.

Thib ob, qhov kev qhia ntawm lub zog ntsuas ntsuas hluav taws xob thiab cov tshuab hluav taws xob

Nws yog ib qho txiaj ntsim zoo los tiv thaiv qhov kev ntsuas kev ntsuas ntawm kev tswj cov kab hluav taws xob ntawm qhov hluav taws xob ntsuas ntsuas. Ua ntej, Peb Thaj Tsa Lub thawv ntu txuas ntxiv ntawm lub zog ntsuas hluav taws xob yuav tsum tau ua raws li cov kev cai: High-pressure TA thaiv, yuav tsum tsis txhob sim yooj yim, thiab daim ntawv thov ntawm cais kab hluav taws xob, uas yog, three-phase three-tel ob tug TA nrog plaub kab, peb theem system nrog peb hauv paus kev txuas. Rau qee qhov low-voltage tseem siv lub simplified thaiv, uas yog, Peb Theem Meter Box peb theem three-line two TA nrog cov hnub qub tsis txuas kev txuas, nrog peb kab txuas; peb-theem plaub-hlau peb TA-star method thaiv, nrog plaub kab.

Thib ob, thaum lub thev naus laus zis hauv TV nrog kev sib txuas nrog kev sib txuas, kev siv plaub cuaj caum, tus tub ntxhais ua tus thaub qab, 35kV lossis ntau tus nqi them nyiaj rau TV, nws yuav tsum tsis txhob nruab ib qhov kev sib txuas lus, tiam sis kev fuse; 35kV thiab qis tshaj tus nqi ntawm Daim Ntawv Cim Thoob Plaws TV, Peb Thaj Meter Box yuav tsum tsis muaj kev sib txuas nrog kev sib txuas lus pab lwm tus neeg thiab cov fuses; 35kV thiab qis dua cov neeg siv ntawm daim ntawv thov ntawm qhov kev ntsuas tshwj xeeb ntsuas; 35kV thiab tshaj cov neeg siv yuav tsum tau TA, TV muag theem siab, tsis nrog kev tiv thaiv, Kev ntsuas voj ntau.

Kev Thoob Xob Nruab Nyog Qib Siab Thoob Plaws Nyuaj Siab Qhov zoo tshaj plaws yog siv cov xim daj, xim ntsuab, liab liab, kab hlau uas muaj cov xaim dub, thiab nruab nrab ntawm cov hlau yuav tsis muaj pob qij txha. Hlau txuas rau cov ntsia hlau crimping, ntsia hlau crimping, Peb Theem Meter Box lub xov yuav tsum raug nplua nplhaib, qhov kev taw qhia ntawm cov zais zawm nrog qhov kev taw qhia tib.
