1. Lub hom phiaj ntawm kab lus no
Qhov tseeb xaim ntawm hluav taws xob hluav taws xob metering ntaus ntawv yog qhov yooj yim ntawm hluav taws xob ntsuas tau, thiab nws muaj feem xyuam rau kev ncaj ncees thiab kev ncaj ncees ntawm hluav taws xob cov nqi them nqi. Cov phiaj xwm fais fab tuam txhab ua haujlwm nqa tawm lub sijhawm ntawm {1} {} Cov ntaub ntawv tsom xam mus kuaj cov kev ntsuas hluav taws xob ntawm kev ntsuas kev ntsuas kom ntseeg tau tias kev ntsuas yog.
Cov xaim ntawm peb {-}} hlau hluav taws xob ntsuas yog cov nyom, thiab cov hom kev tsis txaus ntseeg yog cov thiab sib txawv. Yog tias hom kev sib txawv tsis yog kev tsis ncaj ncees, nws yuav ua rau txoj kev kho kev kho hluav taws xob yuam kev, yog li ua rau cov khoom siv hluav taws xob tshiab. Taking a case of repeated wiring abnormality as an example, this article analyzes the judgment method of wiring abnormalities such as voltage co-line and the causes of error correction, helping metering personnel to accurately judge the abnormality type and help improve quality and efficiency.
2. Cov lus piav qhia
Thaum lub sijhawm ua ntu zus rau - chaw soj ntsuam pom tias cov hlau hluav taws xob ntawm ib qho kev sib xyaw nrog cov kab hluav taws xob theem. Tom qab kho rau ntawm qhov chaw, qhov kev soj ntsuam tom ntej tau pom tias cov kab hlau ntawm cov khoom siv tseem tsis yog thiab cov yam ntxwv tsis zoo
Tom qab cov xaim yog pauv, cov pasor tam sim no yog cov cim txuas ntxiv nyob rau hauv daim ntawv ntawm cov ntsiab lus uas tawg, thiab cov xov tooj uas siv xov hluav taws xob rau tag nrho ib hnub yog kos. Los ntawm cov duab kos, cov neeg siv lub nra ruaj khov, ntsuas lub kaum lub zog yog ib txwm nyob ib puag ncig 0 degree, dhia ntawm kev muaj peev xwm thiab muaj peev xwm.

Cov voltage, tam sim no, thiab voltage - Lub kaum tam sim no ntsuas los ntawm peb Cheebtsam tau pom nyob hauv qab rooj hauv qab no.
Nyob rau hauv lub rooj, lub hwj chim muaj lub kaum ntawm 179.2 Qib ntsuas los ntawm lub theem thib ob yog sawv cev rau lub kaum sab xis ntawm U1 thiab U2. Xav tias lub kaum sab xis ntawm U1 thiab U2 yog 120 degree, lub kaum sab xis ntawm U2 thiab I2 yog qhov tseeb 59.2 degree. Lub sijhawm no, ntsuas ntsuas tau sawv cev rau cov khoom ntawm peb {}}}}}}}} Cov qauv siv hluav taws xob ib txwm muaj.
Thaum lub meter cov neeg ua haujlwm tau kho rau ntawm lub xaib, lawv tau thim rov qab tam sim no B, yog li hluav taws xob xaim hluav taws xob tom qab kho tau:
3.2 Cov yam ntxwv tsis zoo
Nyob rau hauv tam sim no Mettering ntsig txog cov specifications, rau peb}}}} {} {{1} {{1} {{1} {{1} {{2} {{2} {{2} { Tus cwj pwm no feem ntau yuav tsum siv cov neeg ua haujlwm rau lub xaib rau kev ntsuas, thiab tom qab ntawd pab txiav txim siab seb cov colfage puas tshwm sim. Thaum lub sijhawm kuaj tej thaj chaw deb, cov neeg ua haujlwm ntsuas yuav rov ua cov yam ntxwv hluav taws xob nrog lub kaum sab xis ntawm 120 degree, los pab txhawb kev txiav txim siab.
