Iindaba-I-Energy Meter's No-load Behaviour

Iimeko kunye neziganeko zeImitha yamandla's No-mthwalo Ukuziphatha

Xa imitha yamandla ingenawo ukuziphatha komthwalo ekusebenzeni, iimeko ezimbini kufuneka zaneliswe.(1) Makungabikho msinga kwisekethe yangoku yemitha yombane;(2) Isilinganisi-manzi sombane akufuneki sivelise ukubetha kombane ngaphezu kwesinye.

Ukuziphatha kokungalayishwa kwemitha yamandla kunokumiselwa kuphela ukuba ezi meko zimbini zingentla zihlangatyezwa ngaxeshanye.Ukuba ukuziphatha okungekho mthwalo kubangelwa ngaphaya kwe-115% ye-voltage yereferensi, ngokwemigaqo echaphazelekayo, imitha yombane ifanelekile, engenakubhekwa njengokuziphatha kokungabikho komthwalo;kodwa xa kufikwa kubasebenzisi, njengoko imbuyekezo yombane ixhalabile, ngokucacileyo kufuneka ithathwe njengokuziphatha okungalayishwanga endaweni yesiqhelo.

Ukuze wenze isigwebo esichanekileyo, uhlalutyo lwenziwa ngokwemiqathango engentla:

I. Akukho msinga kwisekethe yangoku yemitha yombane

Okokuqala, umsebenzisi akasebenzisi ukukhanya, abalandeli, iTV kunye nezinye izixhobo zendlu, oko akuthethi ukuba akukho okwangoku kwisekethe yangoku yombane wombane.Izizathu zezi zilandelayo:

1. Ukuvuza kwangaphakathi

Ngenxa yokonakala, ukonakaliswa kokugquma kweengcingo zangaphakathi kunye nezinye izizathu, uqhagamshelo lombane lwenzeka emhlabeni kwaye ukuvuza komsinga kunokwenza isilinganisi-manzi sisebenze ngexesha lokuvala.Le meko ayihambelani nomqathango (1), ngoko ke akufanele ithathwe njengokuziphatha okungekho mthwalo.

2. Thatha imitha ye-sub-energy eqhagamshelwe kwimitha engundoqo njengomzekelo.Ifeni yesilingi ngaphandle kweblade ivulwa ngempazamo ebusika.Nangona kungekho kusetyenziswa kombane ngokucacileyo ngaphandle kwengxolo kunye nokukhanya, imitha yombane ibisebenza ngomthwalo, kwaye ngokuqinisekileyo ayinakuthathwa njengokuziphatha kokungalayishwa.

Ngoko ke, ukuze kuqinisekiswe ukuba imitha yamandla ombane ngokwayo ayisebenzi kakuhle akukho mthwalo osebenzayo, utshintsho oluphambili kwi-terminal yemitha yamandla ombane kufuneka luqhawulwe, kwaye umgca wesigaba ekupheleni komphezulu wokutshintshwa kufuneka unqanyulwe kwezinye iimeko. .

II.Imitha yombane akufuneki ivelise ngaphezu kwepulse enye

Emva kokuqinisekisa ukuba akukho okwangoku kwisekethe yangoku yemitha yombane, kunokumiselwa ukuba akukho mthwalo wokuziphatha okanye awusekelwe kwinto yokuba ukukhanya kwe-pulse kukhanya okanye cha.Uvavanyo lovavanyo lwemitha aluyi kuba nepulse engaphezulu kwesinye.

Emva kokuqinisekisa ukuba akukho mthwalo, qaphela ixesha t(umzuzu) wepulse nganye kunye ne-c(r/kWh) engatshintshiyo yemitha yombane, kwaye ubuyisele intlawulo yombane ngokwale fomula ilandelayo:

Umbane obuyiselweyo: △A=(24-T) ×60×D/Ct

Kwifomula, i-T ithetha ixesha lokusebenzisa umbane imihla ngemihla;

D kuthetha inani leentsuku zokuziphatha kwemitha yombane yokungalayishi.

III.Ezinye iimeko zokuziphatha kwemitha yombane yokungalayishi:

1. I-coil yangoku i-short-circuiting ngenxa yomthwalo ogqithiseleyo kunye nezinye izizathu, kwaye i-voltage ye-voltage flux magnetic ichaphazeleka kule nto, eyahlula ibe ngamacandelo amabini e-flux kwindawo eyahlukileyo kunye nexesha elihlukeneyo, okubangela ukuba akukho mthwalo osebenzayo.

2. Imitha ye-watt-yure esebenzayo yesigaba sesithathu ayifakwanga ngokulandelelana kwesigaba esicacisiweyo.Ngokuqhelekileyo, imitha yesigaba sesithathu kufuneka ifakwe ngokulandelelana kwesigaba esilungileyo okanye ukulandelelana kwesigaba esifunekayo.Ukuba ufakelo lokwenyani alwenziwanga ngokweemfuno, ezinye iimitha zamandla ziphazamiseke ngokunzulu yi-electromagnetic ngamanye amaxesha aziyi kuwenza umthwalo wokuziphatha, kodwa unokupheliswa emva kokulungisa ukulandelelana kwesigaba.

Ngamafutshane, emva kokuba ukuziphatha okungekho mthwalo kwenzeka, akuyimfuneko kuphela ukujonga imeko yemitha yombane ngokwayo, kodwa ngamanye amaxesha uhlolisise i-wiring kunye nezinye izixhobo zokulinganisa.
