Li cas los ntsuas inductance nrog multimeter?
Nrhiav tau cov xim cim inductors
Tso qhov tso rau hauv R × 1 txoj haujlwm, thiab txuas cov xim liab thiab dub ua rau cov hmoov txhuas ntawm cov xim code inductor. Txij ntawm no, tus pointer yuav tsum viav vias mus rau sab xis. Raws li ntsuas cov nqi tiv, nws tuaj yeem sib txawv rau hauv peb kis:
Cov nqi tiv thaiv cov xim ntsuas ntawm cov xim kuaj cov xim code inductor yog xoom, qhia tau ib qho kev ua txhaum sab hauv luv -} Circuitation txhaum. Qhov ntau ntawm DC qhov tseem ceeb ntawm cov xim kuaj cov xim code inductor yog hais txog qhov taub uas siv los qhwv lub inductor coil thiab tus naj npawb ntawm hloov qhov txhab. Ntev npaum li ntev li cov nqi tiv thaiv tau tuaj yeem ntsuas tau, nws tuaj yeem suav tau tias cov xim ntsuas xim inductor yog li qub.
2. Kev tshuaj xyuas ntawm Zhongzhou Transformer
A? Teeb lub multimeter rau r × 1 thiab xyuas cov xwm txheej ntawm txhua tus ntawm ib qho raws li tus pin hloov pauv, txhawm rau txiav txim siab yog tias nws yog qhov qub. B? Kuaj Rwb Thaiv Tsev Kev Ua Haujlwm
Tso qhov tso rau hauv r × 10k ntau thiab ua cov ntawv xeem hauv xeev:
(1) Cov nqi tiv thaiv tsis kam ntawm thawj lub winding thiab qhov kev txhaj tshuaj tiv thaiv kab mob theem nrab;
(2) Cov nqi tiv thaiv tsis kam ntawm thawj qhov cua thiab lub casing;
(3) Cov nqi tiv thaiv tsis kam ntawm theem ob thiab lub casing.
Cov kev ntsuam xyuas saum toj no tuaj yeem faib ua peb qho xwm txheej:
(1) Cov nqi tiv thaiv tsis kam yog qhov tsis kawg: ib txwm muaj;
(2) POO ZERAIGTANCE: Muaj ib qho luv luv-} Circuit Secrcuit Secgres;
(3) tsis kam tsawg dua li infinity tab sis ntau dua pes tsawg tshaj xoom: muaj kev ua txhaum cai.
3. Kev tshuaj ntsuam ntawm lub zog hloov hluav taws xob
A? Txheeb xyuas cov kev tsis pom tseeb los ntawm kev pom cov tsos ntawm lub transformer. Whether the coil leads are broken, desoldered, whether there are burnt marks on the insulation material, whether the iron core fastening screws are loose, whether the silicon steel sheets are corroded, whether the winding coils are exposed, etc.
B? Rwb thaiv tsev xeem ntawv. Ntsuas cov txiaj ntsig tsis kam ntawm cov hlau core thiab thawj zaug, nruab nrab ntawm cov hlau thiab nruab nrab ntawm txhua qhov kev nyab xeeb, nruab nrab ntawm txhua qhov cua ntawm theem nrab uas siv tus multimeter r ultionation r ultionation r ultionation r ultion anch 10k. Lub pointer Meratus yuav tsum tag nrho cov taw tes rau infinity thiab nyob twj ywm nyob ruaj ruaj. Txwv tsis pub, nws qhia tau tsis zoo rwb rwb thaiv tsev kev ua tau zoo ntawm lub transformer.
