Txoj kev txiav txim rau tib lub npe kawg ntawm peb theem Asynchronous Tsav Windings nrog Multimeter
Txoj Kev 1: Daim duab peb sab kev sib txuas ntsuas txoj kev
Kauj Ruam 1: Teem lub multimeter rau R × Ntsuas rau 6 cov xov hlau tawm thiab ob lub hauv paus ntawm lub cev muaj zog hlws ris lub thawv ntawm 100 lub zog los txiav txim siab peb theem winding.
Cov txheej txheem tshwj xeeb; Txuas lub xov tooj liab (los yog dub) mus rau ib qho ntawm cov hlau lead; Tus cwj mem dub (lossis liab) hu rau lwm tsib cov hlau lead hauv ib ntus; Ob lub terminals tawm ntawm cov channel (xa mus rau qhov loj deflection thiab tsis tshua muaj zog) yog nyob rau hauv ib theem thiab cim (nws pom zoo kom siv knotting los yog xim raws li cov cim cim) kom paub qhov txawv ntawm ob theem hauv qab no, thiab lwm yam, faib cov rau txoj kab tawm mus rau peb pawg.
Kauj ruam 2: Teem lub multimeter mus rau qhov tam sim no microampere ntau yam, thiab xyuas cov xaim raws li qhia hauv daim duab los txiav txim qhov pib thiab xaus ntawm ob-theem winding.
Cov txheej txheem tshwj xeeb:
(1) Teem lub multimeter rau qhov tam sim no microampere ntau yam;
(2) Txuas cov xov tooj liab thiab dub ntawm lub multimeter mus rau ob qhov kawg ntawm ib qho winding ntawm lub cev muaj zog;
(3) Tom qab ntawd, hu rau ob qhov kawg ntawm lwm theem ntawm lub cev muaj zog nrog qhov tsis zoo thiab qhov zoo ntawm cov roj teeb kilowatt (lossis tshem lub roj teeb ntawm multimeter rau kev sim) E (9V lossis 1.5V roj teeb);
(4) Yog hais tias tus pointer ntawm lub multimeter yog deflected nyob rau hauv qhov zoo kev taw qhia, lub zoo davhlau ya nyob twg ntawm lub roj teeb thiab qhov tsis zoo davhlau ya nyob twg (dub sojntsuam) ntawm lub multimeter muaj tib lub davhlau ya nyob twg. Ntawm qhov tsis sib xws, lub davhlau ya nyob twg ntawm qhov tsis zoo electrode ntawm lub roj teeb thiab lub davhlau ya nyob twg ntawm cov hlau tsis zoo (dub cwj mem) ntawm multimeter yog tib lub npe. Raws li pom hauv daim duab, thawj (lossis kawg) kawg yog cim nrog lub cim dub, uas txhais tau tias qhov kawg nrog tib lub npe. Siv tib txoj kev, txiav txim siab qhov pib thiab qhov kawg ntawm lwm theem dua.
Txoj Kev 2: Kev ntsuas kev sib txuas hnub qub
Kauj ruam 1: Txiav txim siab peb-theem winding (txoj kev yog tib yam li saum toj no, nco ntsoov tias tom qab txhua theem tau kuaj pom, cov cim yooj yim thiab meej yuav tsum tau ua kom paub qhov txawv ntawm peb theem stator winding).
Kauj Ruam 2: Kev sib txuas hnub qub txiav txim siab thawj zaug thiab kawg kawg ntawm peb-theem winding
Cov txheej txheem tshwj xeeb:
(1) Teem lub multimeter rau microampere txoj hauj lwm;
(2) luv luv Circuit Court ib kawg ntawm txhua peb windings ntawm peb-theem asynchronous lub cev muaj zog ua ke nrog cov hlau lead liab, txuas rau lwm qhov peb xaus ua ke, thiab tom qab ntawd txuas nrog cov hlau lead dub;
(3) Tig lub cev muaj zog ntawm qhov ceev tsis tu ncua thiab saib xyuas qhov deflection ntawm tus taw tes;
(4) Yog hais tias tus pointer yuav luag tsis muaj deflection, peb xaiv cov hlau xaus ntawm txhua qhov winding txuas ua ke yog tib lub npe xaus (raws li qhia hauv daim duab 3). Txwv tsis pub, kev hloov kho hlau yuav tsum tau ua.
2. Kab hloov qauv:
(1) Kos qhov pib thiab qhov kawg ntawm peb windings cais, thiab cia tus lej pin.
(2) Ib txheej ntawm windings (xav tias yog terminals ⑤ - ⑥) yog ib txwm kho raws li qhov siv.
(3) Tom qab ob qho tib si ntawm ob pab pawg sib koom ua ke, sib txawv raws li cov txheej txheem tshwj xeeb (1) - (4). Yog tias tseem muaj qhov sib txawv, tom qab ntawd los ntawm kev ua kom lub taub hau thiab tus Tsov tus tw ntawm lwm pab pawg thiab siv cov txheej txheem tshwj xeeb xws li "1) - (4)", qhov tseeb homonymous kawg tuaj yeem txheeb xyuas tau.
