Kuti anoyera voltmeter? Mudziyo nokuti kuyera munhu voltage

Man, kure zvemagetsi nematunhu, voltage, kuitika uye nemishonga, asingatombokwanisi pakarepo kupindura mubvunzo: chii anoyera voltmeter? Nokuti mhinduro iri pachena, kana iwe chete kuverenga chechipiri hafu yacho rokuremekedza, zvinoratidza zvishoma nyaya iyi. Kunyanya, funga nokuyerwa kunetseka muupenyu hwezuva nezuva, zvinoitwa huchashandiswa, kuti uchishandisa pfungwa.

tsananguro

Voltmeter - tambo mudziyo kubvumira kuwana voltage kana electromotive simba mune ngetani zvakananga kana rakatumbuka ano. Mudziyo siyana ingangowedzera kusvika 1000 kana kupfuura. Zvose zvinoenderana chinangwa chawo. Kuti tinzwisise zviri nani chii, isu funga tsanangudzo electromotive simba. Nekuti kazhinji zviri kuvhiringidzwa voltage iri pomumbure, vanofanira kuparadzaniswa mumwe.

EMF uye Voltage: musiyano

Nokudaro, EMF - muviri kwazvo kuti kunozivisa basa kuitwa chero mauto asiri nemagetsi ari kufamba rimwe zvakanaka mutariri munzira ano. In yenguva dzose nyaya, zvinoratidza mano nesimba panobva kuumba rimwe zvinogona musiyano vaviri munzvimbo dzokuzororera dzaiva tisingabatanidzi pfungwa yacho cheni iri. Zvinonzi akayera sezvo voltage mu volts. Zvakasiyana nawo kuti zvinopa tsime simba usimbe, kureva pasina nomumbure kubatana.

Kana redunhu ane kuitika, kureva, zvinonzi akavharwa, pane mumwe, zvikuru yaizivikanwa rokunzwikwa - voltage. Uyezve, anogona kutorwa zvose simba nerubatsiro panguva zviteshi zvayo, uye chero chikamu cheni. Voltage chipimo ndiko kuziva miedzo dzingangoitika musiyano pakati maviri munzvimbo dzokuzororera dzaiva pfungwa. Nokuti simba panobva Kazhinji yakati muduku kupfuura electromotive simba, kana dziri mutengi redunhu. Zvikurukuru, uye emf voltage uye - ndiyo chete ine musiyano chete pakuti chaiko kwacho zvinowanisa nezve zvinogona musiyano pakati maviri pfungwa panguva iyo nokuyerwa chinobviswa.

mhando voltmeters

Pano tinofanira kusiyanisa mhando huru mbiri: inotakurika uye wakaiswa. Portable mudziyo nokuti kuyera voltage haagoni chete achizvuzvurudza manually. Yemanyorero zvinosanganisira functionality kuongorora zviri dzenzvimbo uye resistances mudunhu, uyewo kondakita tembiricha, etc. Mira hurongwa kazhinji aibatanidza zvayakaita pamwe pomumbure, sezvamakaropafadzwa nokuyerwa rinoitwa Somuenzaniso, mune zvemagetsi kuparadzirwa mapuranga, ukomba etc.

Maererano kupatsanura pakati nheyo chiito, tinogona musiyano wemarudzi anoverengeka electromechanical voltmeters maviri mhando Erekitironi. Last - ndiko analoginen uye digitaalinen. Electromechanical voltmeters vanoshandisa simba rinonzi magnetic kutendeutsa marongedzero pakugamuchira voltage tsika. Zvemagetsi digitized wakagamuchira chiratidzo uchishandisa ADC. Voltmeter, zvichienderana umbowo kumiririrwa nheyo kuratidza kana wakaita raundi chokukomborerwa kana akazvitsaurira-digital kuratidzwa.

Chimwe kupatsanura - iri chinangwa. Kunoitawo kuti kugoverana mano pamusoro metres AC uye DC uyewo Pasika-nehanya, zvechivhurumukira uye tigone kushanduka. Nokuti yokupedzisira anowanikwa rinenge gamut yose mureza voltage riri zvakakodzera kudzidza.

Basic nokurondedzerwa

It kunobva kuenda mudziyo. Somuenzaniso, DC voltmeter kazhinji ane vanoverengeka kuyera neeSultan, saka nhamba yavo chimwe chezvinhu zvinokosha nokurondedzerwa. Uyezve, anenge mano ose vane imwe chiyamuro impedance zvichienderana, Sezvineiwo, pakuti icho bvunzo redunhu ndiye voltage rangano.

Chimwe maitiro zvinokosha, Chokwadi, kutadza, uye chisarudzo pamusoro pamwero kana shoma danho kuverenga, kana kutaura digitaalinen voltmeter. Kana mushandisi angosimuka zano yezvisikwa kuti kuyera voltage, anogona kuwedzera pamusoro variables kunze nawo anogona ishande Somuenzaniso, uno, nemishonga, tembiricha, uye neeSultan, uye kakawanda kukanganisa anonongedzera kuti variables.

musimboti oparesheni

General Zano kushanda mudziyo uri zvikuru novimba Implementation. Kana ichi ndicho electromechanical voltmeter ane simba rinonzi magnetic gadziriro, inonyatsoziva mudare chokubuda. Zvichienderana ayo nokukura, uye inowedzera kutsaudzira Pointer miseve mechanically pamwe redunhu puranga kana chimwe chinhu chinoshandiswa kutendeutsa kuitika mudunhu. Kururama kwakadaro mano hakusi kukuru, sezvo haabvumiri kuwana dzakakwirira tsika chiyamuro resistors, uye nokudaro anobatsirawo chinokosha kusarurama nechiyero, sezvo parasitic conductivity inowedzerwa remudunhu.

Common mumakore achangopfuura mune digitaalinen voltmeters vane vazhinji musha zvemagetsi pasi Hood. Izvi imhaka Kutendeuka analogue chiratidzo ikabereka pa mazano zviteshi, kupinda digital chimiro uchishandisa ADC. Izvi zvinofadza chaizvo, inowanika ane yakawanda mabhuku panyaya. voltmeter kwakadaro, mutengo iyo zvichisiyana mashomanana zana rubles Chokwadi, kwete aida kuva mupfumi kusarudzwa mikana uye kururama kukuru, zvisinei, zviri anokwanisa zvizere kuyera voltage panguva zviteshi mumotokari bhatiri kana 220 V.

Unobatanidza kuti mudunhu

The voltmeter Dunhu iri nguva dzose chokuita akaererana mutoro kana simba bhuku, kana zvakakodzera kuyera electromotive simba kana chirwere voltage. Ndokusaka pane kuomesa zvinodiwa kuti mazano kuramba ari mudziyo, sezvo kubatana akadaro anotora chimiro kweimwe conduction mudunhu.

Chero zvazvingava, regai batanidza munhu voltmeter, mutengo izvo chero mukuru, ari mudunhu iri akatevedzana. Zvikasadaro inodzidzisa anomhanya mukana corny kokutsva Unit, uye vasina nguva kuwana zvinhu zvose chakatangwa. kunyange kana hunomira ari ufuza chikumbiro, uchapupu hwake harifaniri kuvimbwa kana, nokuti kuitika mudunhu iri anozadziswa kuchinja zvikuru maererano iyi voltmeter, zvakare kuda kupinda asingazivikanwi mukana wokudzidza chaiko voltage nharaunda umo kuyerwa dzinoitwa.

Kudzora chenjedzo

Sezvo kurwisa zviri voltmeter kakawanda zvakakwana guru uye wiring diagram, ukuwo, anoshandiswa zvakafanana, mukana wokusvika chakakomba zvemagetsi kuvhunduka low voltage redunhu riri shoma. Zvisinei, kana kutaura maindasitiri mano, kunyanya yakatarwa shanduro, kunosanganisira kukuru chakayerwa tsika somunhu voltage, uye chinowanzoitika dzenzvimbo. Naizvozvo, panofanira kuva kuchengeteka panguva chikuru sandara, uye pasina ruzivo rwakakwana, rabha Magorovhosi Chipfeko, nepanhovo uye nedzimwe nzira yakakodzera, Chokwadi, chero basa iri contraindicated. Chii anoyera voltmeter kungangova nengozi chaizvo kuti upenyu, saka tinoratidza kwete kuedza mugumo. Chero zvazvingava kuti kubata miti waya, kunyange kana neyamapani voltage redunhu, kubudikidza tsanangudzo, musaita.

mhedziso

Kupindura mubvunzo pamusoro chii anoyera voltmeter, isu akatarisa zvavo nemashoko nechivako kwayo, chikuru zvekushandisa maitiro, kupatsanura. Chokwadi, ichi muchidimbu pfupi haazviti nzwisisika kukwana, kunyanya mu pasi rakawanda zivo inokosha zvemagetsi okugadzira panguva muverengi.

Achiratidza, zvinofanira kucherechedzwa kuti voltmeter zviyero Chokwadi, ari voltage riri wedunhu mugove iyo hwakabatana mu zvakafanana. Zvikasadaro, uchapupu vake vaizova wokusavimbika, tisingatauri zvakaipira zvichibvira kurasikirwa michina zvinodhura. Muverengi anofanira kungwarira kana kushandisa mudziyo mumba, nokuti kuonana mukuru-voltage redunhu kunzvimbo ngozi kuupenyu.
