Txoj kev txiav txim qhov zoo ntawm lub cev muaj zog los ntawm multimeter
Muaj peb-theem motors thiab ib-theem motors, thiab ib-theem motors muaj peb kab thiab rau kab.
peb-theem lub cev muaj zog
Rau kais rau peb-theem winding ntawm theem lub cev muaj zog. Cia peb ua ntej tshem tawm qhov txuas txuas txuas ntawm lub tshuab hluav taws xob. Ntsuas qhov pib thiab qhov kawg ntawm txhua theem winding nrog ib tug multimeter kom pom tias nws nyob los yog tawm. Tom qab ntawd siv multimeter los ntsuas qhov tsis kam ntawm txhua ob-theem winding, tsawg kawg ntau dua 0.5 megohm, thiab ntau dua qhov zoo dua. Thaum kawg, ntsuas qhov rwb thaiv tsev tiv thaiv ntawm txhua theem winding thiab lub plhaub lub cev muaj zog, uas yuav tsum tsis muaj qhov kawg. Nyob rau hauv txoj kev no, qhov zoo ntawm peb-theem lub cev muaj zog tuaj yeem txiav txim tau yooj yim.
Ib-theem lub cev muaj zog nrog peb xaim
Lub cev muaj zog unidirectional tsuas muaj ob lub windings, pib winding thiab khiav winding. Ib qho ntawm peb cov xov hlau yog lawv cov xov hlau, uas yog, ib qho kawg ntawm ob-theem winding txuas ua ke. Qhov thib ob yog lwm cov kais dej ntawm ob-theem winding.
Qhov kev tawm tsam ntawm ob lub kais dej yuav tsum yog qhov siab tshaj plaws thiab sib npaug ntawm qhov sib npaug ntawm qhov kev ua haujlwm ntawm ob lub windings.
Tau kawg, peb yuav tsum ntsuas qhov kev tawm tsam ntawm lub kauj thiab lub casing kom pom tias nws tau tawg lawm. Tau kawg, qhov ntau dua qhov tsis kam, qhov zoo dua, thiab qis tshaj yog tib yam, tsis tsawg dua 0.5 megohm.
6-wire ib-theem lub cev muaj zog
Muaj rau kab, qhov tseeb, ob kab (Z1, Z2) yog centrifugal hloov kab. Hom lub cev muaj zog no kuj muaj rau terminals, yog li nws cov khoom txuas yuav tsum raug tshem tawm. Tshem tawm lub capacitor, thiab tom qab ntawd ntsuas qhov kawg ntawm ob-theem winding thiab qhov tsis kam ntawm ob-theem windings feem. Txoj kev yog tib yam li ntawm peb-theem lub cev muaj zog.
Siv multimeter los txiav txim qhov zoo ntawm lub cev muaj zog tuaj yeem tsuas yog kev txiav txim ua ntej. Lub rwb thaiv tsev tiv thaiv ntawm windings thiab rwb thaiv tsev tsis kam ntawm txhua theem winding rau hauv av yuav tsum tau ntsuas los ntawm megger kom raug ntau dua.
Tsis tas li ntawd, luv luv Circuit Court ntawm lem ntawm winding tsis tuaj yeem ntsuas. Peb tsuas tuaj yeem kwv yees seb puas muaj qhov luv luv ntawm kev sib hloov los ntawm kev sib piv. Piv txwv li, cov qauv winding ntawm ib theem yog ntau me dua li ntawm ob theem, yog li peb tuaj yeem xav tias nws tau tig-rau-tig luv luv.
