Kuti amaona voltmeter? Chipangizo kuona ndi voteji

Man, kutali madera magetsi, voteji, panopa ndi kukana, nkomwe amatha yomweyo muyankhe funso ili: amaona zimene voltmeter? Chifukwa yankho ndi lodziwikiratu, kungowerenga theka lachiwiri la mutu nkhani, awulule pang'ono nkhaniyi. Makamaka, taganizirani muyeso wa nkhawa pamoyo, makhalidwe a chida cha, mfundo opaleshoni.

tanthauzo

Voltmeter - chingwe chipangizo kulola kupeza voteji kapena mphamvu electromotive mu unyolo wa mwachindunji kapena alternating panopa. Chipangizo osiyanasiyana angakhale okhudza mpaka 1000 kapena zambiri. Izi zidalira pa cholinga chake. Kumvetsetsa icho chiri, timaona tanthauzo la mphamvu electromotive. Chifukwa nthawi zambiri izo kusokonezedwa ndi voteji mu maukonde, iwo ayenera anapatukana.

EMF ndi Voteji: kusiyana

Choncho, EMF - ndi kuchuluka thupi kuti amadziwika ntchito ndi mphamvu iliyonse sanali magetsi kayendedwe ka limodzi mlandu zabwino tikuyenda pa njira panopa. Pankhani mwachizolowezi, izo zikusonyeza mphamvu ya gwero mphamvu kulenga makamaka kuthekera kusiyana mu awiri spaced popanda mfundo unyolo. Iwo anayeza monga voteji mu volts. Kumasiyana ndi mu kuti lili gwero la mphamvu chabe, kuti popanda kugwirizana Intaneti.

Pamene dera ali panopa, mwachitsanzo, kuti chatsekedwa, pali wina, bwino mfundo kumva - voteji. Komanso akhoza kumwedwa kwa onse chakudya mphamvu pa malo ake, ndipo mu gawo lirilonse la unyolo. Voteji muyeso ndi kudziwika kusiyana ulipo pakati pa mfundo ziwiri spaced. Gwero mphamvu zambiri penapake zosakwana mphamvu electromotive, pamene m'gulu ogula dera la. Kwenikweni, ndi emf voteji ndi - izi ndi chimodzimodzi ndi kusiyana kokha ndondomeko thupi amapanga maonekedwe a kusiyana ulipo pakati pa mfundo ziwiri zomwe muyeso watengedwera.

mitundu voltmeters

Apa tiyenera kusiyanitsa mitundu ikuluikulu iwiri: kunyamula ndi lokhazikika. Zam'manja chipangizo kwa kuyeza voteji silingakhoze kokha kokani pamanja. Childs amaphatikizapo magwiridwe kwambiri poona mafunde ndi resistances mu dera, komanso ngati wochititsa kutentha, etc. kachitidwe n'kupuma nthawi zonse anali kuphatikiza amapanga ndi maukonde, mmene muyeso wa ikuchitika Mwachitsanzo, mu magetsi yogawa matabwa, mapanelo etc.

Pankhani gulu la mfundo kanthu, tingasiyanitsire mitundu yambiri ya voltmeters electromechanical ndi mitundu iwiri ya elekitironi. Last - ndi analogi ndi yadigito. voltmeters Electromechanical ntchito dongosolo maginito kutembenuka kulandira mfundo voteji. zamakono digitized analandira chizindikiro ntchito ADC. Voltmeter, malingana ndi chifaniziro deta za mfundo kusonyeza mwina oyimba chizindikiro kapena pa wodzipereka digito anasonyeza.

Gawo lina - pa cholinga. Timatha inu kugawana zipangizo pa mamita AC ndi DC komanso gawo-tcheru, mopupuluma mofewa. Cha mtsogolo alipo pafupifupi gamut lonse la voteji chizindikiro chimene amafunikira kuphunzira.

specifications Basic

Izo zimatengera chipangizo kopita. Mwachitsanzo, DC voltmeter kawirikawiri amakhala ranges angapo kuyeza, kotero chiwerengero chawo ndi imodzi mwa specifications zofunika kwambiri. Komanso, pafupifupi zipangizo zonse ndi zina athandizira impedance malingana, poyamba pa mlingo umene mayeso dera ndi voteji chiwembu.

makhalidwe wina ofunika, ndithudi, kulakwitsa, ndi chigamulocho wa sikelo kapena sitepe osachepera kuwerenga, pamene tikukamba za voltmeter yadigito. Ngati wosuta ali ndi chipangizo chilengedwe kuona voteji, mwina zidzawonjezedwa kwa zosintha pamwamba kunja ndi chimene angathe ntchito Mwachitsanzo, panopa, kukana, kutentha, ndi ranges, ndi chizindikiro pafupipafupi mphulupulu zosintha.

Mfundo ntchito

General chiwembu cha kugwira ntchito chipangizo amadalira kwambiri kukhazikitsa lapansi. Ngati ndi voltmeter electromechanical ali ndi dongosolo maginito, amakhudzidwa otaya panopa. Malinga ukulu wake, ndi kumawonjezera kupatuka Cholozera mivi umakaniko pamodzi ndi chimango dera kapena chinachake kuti ntchito kutembenuza pano mu dera la. Kulondola zipangizo si kwambiri, chifukwa salola kupeza mfundo zabwino za resistors athandizira, motero kumathandiza kwambiri kupotoza muyeso, kuyambira madutsidwe parasitic anawonjezera kuti dera la.

Common zisakuyenda mu voltmeters digito ndi ambiri zamagetsi kunyumba pansi pa nyumba. Ichi ndi chifukwa kutembenuka kwa mbendera analogue akupangidwa ku malo athandizira, mu mawonekedwe digito ntchito ADC. Iyi ndi chidwi, amapezeka ndi mabuku ambiri pa nkhaniyi. Chotero voltmeter, ndi mtengo umene umasiyana rubles mazana angapo, ndithudi, sinafike kusankha wolemera mwayi ndi olondola kwambiri, komabe amatha kwathunthu kuyeza voteji pa malo a batire la galimoto kapena 220 V.

Polumikiza dera la

The voltmeter dera nthawizonse olumikizidwa likufanana ndi katundu kapena mphamvu zoyendetsera, ngati kuli koyenera kuyeza mphamvu electromotive kapena voteji osachiritsika. N'chifukwa chake pali zofunikira okhwima kuti kukana Muzifunsa chipangizo, kuyambira kugwirizana amenewa kukutanthauza maonekedwe a conduction zina mu dera la.

Mulimonsemo, musati kugwirizana ndi voltmeter, mtengo umene mwa njira iliyonse yaikulu, mu dera mndandanda. Apo ayi wosuta limayenda chiopsezo corny lamoto wagawo, ndipo alibe nthawi kupeza zinthu zimene zonse linayambika. Ngati ngakhale maimidwe ndi woipitsitsawu apilo umboni wake sayenera anadalira, chifukwa masiku ano dera la wayamba kusintha kwambiri pa nkhani imeneyi ndi voltmeter, kachiwiri akukankha mu mwayi osadziwika kuphunzira voteji malo enieni amene miyezo anapangidwa.

Kuthana kusamala

Popeza kulimbikira voltmeter mu nthawi zambiri mokwanira lalikulu ndi Kulumikizana chithunzi, motero, ntchito yomweyi, pa chiopsezo chotenga lalikulu magetsi mantha mu dera otsika voteji ndi kochepa. Komabe, pamene akulankhula za zipangizo mafakitale, makamaka Baibulo lokhazikika, pali wautali kwambiri mfundo mpandawo monga voteji, ndipo zikuoneka kuti mafunde. Choncho, ayenera kukhala chitetezo pa mlingo wapamwamba, ndipo popanda kudziwa zokwanira, magolovesi, mphasa ndi njira zina zoyenera, ndithudi, ntchito iliyonse ndi contraindicated. Kodi amaona voltmeter angakhale oopsa kwambiri kwa moyo, Mpofunika osati poyesa tsoka. Mulimonsemo kukhudza mawaya umboni, ngakhale otsika-voteji dera ndi tanthauzo, satero.

Pomaliza

Tsatirani funso lokhudza zimene amaona voltmeter, ife anayang'ana pa mawu onse matabwa ake, chachikulu luso makhalidwe, gulu. Kumene, mwachidule mwachidule sanafotokoze chokwanira mabuku, makamaka ndalama otsika Kudziŵako za ukachenjede magetsi pa owerenga.

Polongosola mwachidule, tisaiwale kuti miyeso voltmeter, ndithudi, voteji pa dera gawo imene chikugwirizana mu kufanana. Apo ayi, umboni wake adzakhala wosadalirika, osanenapo kuopsa imfa zotheka zida mtengo. wowerenga ayenera kusamala pamene ntchito chipangizo chamagetsi kunyumba, chifukwa kukhudzana ndi mumachitika voteji dera ndi ngozi moyo.
