Kev hloov hluav taws xob thaiv tam sim no

(1) Txhawm rau kom paub tseeb tias muaj kev txhaum siab xws li qhov tsis muaj qhov txuas lossis luv luv Circuit Court nyob rau sab ntawm lub tshuab hloov pauv tam sim no, tus neeg xyuas pib txuas nrog qhov hluav taws xob davhlau ya nyob twg ntawm theem A ntawm lub ntsuas hluav taws xob. C-theem voltage davhlau ya nyob twg tuaj yeem raug txiav tawm mus ua tiav, thiab lub ntsuas hluav taws xob hluav taws xob yog lub disc yuav tsum tig. Yog tias The A voltage voltage tawg thiab lub disc tsis tig, nws qhia tau hais tias tam sim no transformer C theem raug cuam tshuam lossis luv luv-ncig. Yog hais tias C-theem voltage hluav taws xob tau tawg thiab lub disc tsis tig, nws qhia tau hais tias tam sim no transformer A theem raug txiav tawm lossis luv-ncig. Yog tias cosg tus nqi ntawm qhov chaw yog ze rau 0.5 (meej meej), txhawm rau kom tsis txhob muaj qhov tsis zoo, qhov theem C voltage yuav raug txiav tawm. Ntxiv rau, theem A A txuas nrog lub ntsuas hluav taws xob muaj peev xwm hloov tau los ntawm theem C voltage. Yog tias lub zog hluav taws xob muaj qhov sib txawv loj, nws tseem qhia tias Ntu A tam sim no tsis tawg, luv luv Circuit Court, thiab lwm yam.

(2) Txhawm rau kom paub qhov txawv ntawm qhov hluav taws xob hloov hluav taws xob hloov pauv, lub galvanometer tuaj yeem txuas mus rau lwm qhov ntawm lub tshuab hloov hluav taws xob tam sim no, thiab siv tam sim no kom paub qhov txawv. Rau lub hnub qub kev sib txuas, thaum lub tshuab hluav taws xob hloov pauv hauv ib theem, Thaum kho qhov muag hluav taws xob rov qab hloov ib zaug lossis ntau dua, qhov theem tam sim no yuav yog ob zaug ntawm lwm theem tam sim no. Yog hais tias tam sim no transformer kho qhov muag kev sib hloov txhua qhov rov qab sib txuas yuav tsum ua kab kos duab vector ntawm lub zog hluav taws xob 'meter' kev sib koom tes thaiv, nws tuaj yeem nkag siab sib txawv.

(3) Hais daws seb qhov tam sim no hloov hluav taws xob hloov pauv yog qhov ntsuas tau qhov tseeb thiab tuaj yeem ntsuas qhov ntsuas nrog qhov ntsuas kab hluav taws xob. Rau kev ntsuas kom raug, ib sab ntawm lub ammeter txuas nrog lub davhlau ya nyob twg ntawm ungrounded ntaus ntawm voltage transformer, thiab lwm qhov kawg kov cov kab ntawm qhov hloov tam sim no. Yog hais tias lub ammeter raug cim li 100V, nws qhia tias qhov hloov hluav taws xob tam sim no yog rov ua dua. Yog hais tias lub ammeter cim li 0, nws qhia hais tias tam sim no transformer tsis muaj cov khoom siv hauv av.

(4) Thaum lub cuab yeej txuas tau txiav txim siab tsim nyog, nws tuaj yeem ntsuas nrog ntsuas nrog qhov ntsuas me me. Yog li ntawd, lub galvanometer yuav tsum tau ua tiav nrog ib lub davhlau ya nyob twg. Cov hlau ntawm lwm lub davhlau ya nyob twg feem tau kov nrog lub davhlau ya nyob twg tam sim no ntawm lub ntsuas hluav taws xob. Yog hais tias lub davhlau ya nyob twg yog qhov cuab yeej nkag siab, lub teeb ntsuas yuav tsum tsis muaj kev ntsuas, thiab lub disk ceev ntawm lub zog hluav taws xob 'meter' tsis puas; yog hais tias lub davhlau ya nyob twg Yog hais tias cov cuab yeej tsis yog hauv av, lub ntsuas hluav taws xob tau cim thiab lub disk ceev kuj tseem cuam tshuam.
