Yuav ua li cas ntsuas 220v submersible twj nrog digital multimeter zoo lossis phem
Yuav ua li cas txiav txim lub 220V submersible twj zoo los yog phem, peb thawj zaug siv ib tug digital multimeter los ntsuas lub hwj chim mov voltage tsis muaj, thiab ces powered rau saib seb lub submersible twj tso kua mis tau tig, los yog buzzing suab, yog hais tias tsis, koj kos lub Raws li cov xwm txheej, hluav taws xob ib qho ntawm peb kab yuav tsis tuaj yeem dhau los ntawm kev sib txuas, lub twj tso kua mis winding hlawv tawm lossis winding grounded luv luv Circuit Court, capacitor puas, bearing hnav, impeller nrog cov khoom txawv teb chaws thiab lub cev ncej jammed.
Ua ntej tshaj plaws, lub rooj digital tau hu mus rau qhov siab tshaj plaws, nrog tus cwj mem liab thiab xim dub los khaws peb kab thiab lub twj tso kua mis lub cev muaj zog tiv thaiv tus nqi, (cov hlau yuav tsum yog qhov zoo) ntsuas qhov ntsuas tus nqi nyob ze rau infinity, qhov zoo dua, yog tias qhov ntsuas tsis kam nyob ze rau xoom lossis kaum tawm ohms rau lub hauv paus luv luv-circuit.
Qhov thib ob, yuav ua li cas txiav txim lub capacitor yog txoj kev zoo los yog phem, qhov dav dav digital multimeter muaj lub luag haujlwm ntawm kev ntsuas capacitor, kev ntsuas tuaj yeem tso tawm tom qab lub capacitor ob tus pins ncaj qha rau hauv lub rooj saum toj Cx jack, xaiv qhov tsim nyog ntau yam, koj tuaj yeem nyeem. cov ntaub ntawv muaj peev xwm tso saib. Yog hais tias lub capacitor zoo, lub capacitance ntawm lub peev xwm tus nqi yuav nyob ze rau tus nqi ntawm multimeter tuaj tos.
Thib peb, qhov tseem ceeb thiab theem nrab winding tsis kam ntsuas kev txiav txim txoj kev, kev ua haujlwm dav dav ntawm winding kuj nqi ntawm ob peb ohms, thaum pib winding tsis kam ntawm kaum ob ohms los yog kaum ntawm ohms ntawm. Yog hais tias qhov ntsuas tsis kam ntawm xoom lossis ob peb Tebchaws Europe qhia tau hais tias lub winding tig luv luv, infinity qhia tau hais tias lub winding yog tawg.
Plaub, ib-theem submersible twj tso kua mis muaj peb terminals, nrog ib tug digital multimeter
Cov ntaub ntawv los ntsuas qhov ntsuas tus nqi ntawm peb cov xov hlau, qhov kev tiv thaiv ntawm ob lub xov hlau loj tshaj plaws txuas nrog rau qhov sib npaug nrog lub capacitor, lwm cov xaim (public) txuas nrog rau ib qho kawg ntawm cov khoom siv hluav taws xob, thiab tom qab ntawd siv cov multimeter resistor los ntsuas cov pej xeem. kawg thiab lub capacitor txuas nrog rau ob qhov kawg ntawm qhov kev tawm tsam ntawm cov xov hlau, qhov tsis kam ntawm lwm qhov kawg ntawm lub hwj chim mov, qhov tsis kam ntawm lwm qhov kawg ntawm tus nqi me ntsis.
