I ana i ka voltmeter? Kekahi mea no ana i ke anakahi uila

Man, mamao aku mai ka pou i puhi ai, anakahi uila, he a me ka ia'ku, aneane hiki ke koke pane i ka nīnau: He aha ana ka voltmeter? No ka mea, o ka pane ua maopopo, ina oe e heluhelu i ka lua o ka hapalua o ka 'atikala inoa, hoike mai i ka uuku hou keia kumuhana. Ma 'ana, noonoo i ke ana o ka stress i kela la i keia ola ana, ke ano o ka mea, i ka pae'ōnaehana rula.

ka wehewehena

Voltmeter - he ana mea i hiki e loaa i ke anakahi uila a electromotive ikaika i loko o ke kaulahao o ka pono a me ka alternatingʻikena. Kekahi mea i huahelu e ana mai i ka 1000 a oi. Ua pau hilinaʻi nui ma luna o kona manao. maopopo i ka maikaʻi mea ia mea, ua noonoo ka wehewehena o electromotive ikaika. No ka loa pinepine ka mea, ua ahakanaka la i ke anakahi uila i loko o ka mea ulana pukapuka, lakou e hookaawaleia aku, mai kekahi i kekahi.

EMF a me anakahi uila: koena unuhi

Pela, ke EMF - mea he physical nui e characterizes i ka hana i hanaʻia e kekahi ole-pou koa ma luna o ka neʻeʻana o ka hookahi maikaʻi e mālama ai ma o kaʻikena alanui. Ma ka mau hihia, e hōʻike i ka hiki ana o ka mana kumu, e hana i ka kekahi Loaʻaʻiaʻana ma loko o ke kaulike hookaawale nui elua o ke kaula. Ua ua anaia mai ka manawa e like me ke anakahi uila ma volts. Ua i kekahi, mai ka mea i loko o ia mea, e hāʻawi aku i ke kumu o ka mana i hana ole ana,ʻo ia hoʻi, me ka mea ulana pukapuka, e pili ana.

A pau ka huakai kaapuni i kaʻikena, 'o ia hoʻi, ka mea, ua paa hou mai la, he mea kekahi, oi mau manaʻo o ka hālāwai hoʻolohe manaʻo - anakahi uila. Eia hoʻi, ka mea i laweʻia no nā ka mana lako ma kona maʻi, a ma kekahi hapa o ke kaula. Anakahi uila ana o ka ka loaʻaʻana o ka Loaʻaʻia likeʻole ma waena o nā makahiki he wahi. No ka mea mana kumu mea nui i kekahi mau mea emi o ka electromotive ikaika, ka wā pū i loko o ka consumer huakai kaapuni. ʻano nui, a me ka emf anakahi uila, a - keia mea i ka ia a me ke koena unuhi wale nō i loko o ia ka hoʻoponopono kaʻina hana paha ke ka helehelena o kekahi ikehu likeʻole ma waena o nā heluʻai ma i ka huahelu ua ia.

ano voltmeters

Here mākou e hoomaopopo ka papa kuhikuhi ano elua: lawe a me ka paa. Lawe lima kūlana kiʻekiʻe no ana i ke anakahi uila,ʻaʻole hiki wale kauo hana lima. Nō kāu e nā functionality no o kéu na paialewa, a e kū'ē'ē mai i loko o ka huakai kaapuni, e like me ka pono me alakaʻi mele wela, etc. Wahi nenoai pinepine hui structurally me ka mea ulana pukapuka, kahi o ka huahelu ua haliia mai la mawaho, no kekahi laʻana, ma ka uila hoi o ka makana papa, Panel etc.

Me ka pili ana i ka Mea Maluna o ka loina o ka hana, ua hiki ke hoomaopopo kekahi mauʻano o electromechanical voltmeters a me nā 'ano o ka huina'ine. Hope - He Analog a me ka kikohoʻe. Electromechanical voltmeters hoʻohanaʻume mākenēki huli ana'ōnaehana no ka loaa ana anakahi uila nā loina. Electronic manaʻo digitized loaa peahi ka hoʻohana 'ana i ka ADC. Voltmeter, ke kaumaha ma muli o ka 'ikepili e hoohalike ai o ka loina o ka hoike ana kekahi i kekahi hōʻike degere anakahi' ole ma ka mea laʻa kikohoʻe 'ia.

Kekahi Mea Maluna - ma ka hana. Ua apono 'oe e kaʻana hala kākou ma luna o mika AC a me DC like hoʻi me ka pae-ikepili koʻikoʻi, impulsive a me ka'ōlewa. No ka mea hope, ua loaʻa kokoke i ka anai gamut o neaiaea anakahi uila i mea pono e aʻo.

XIX. hoakaka

Ua hilinaʻi nui ma ka mākaʻikaʻi noonoo. No ka laʻana, ka DC voltmeter ana loaʻa paha kekahi mau ana papa koa, no laila lākou helu o kekahi o na hoakaka loa nui. Eia hou kekahi,ʻaneʻane a pau i na mea maalea i ka kekahi hoʻokomo o impedance kaumaha, incidentally, ma ka loa, e a ke hoao huakai kaapuni o ke anakahi uila'āina.

Kekahi nui ano e, o ka papa, i ka hewa, a me ka hooholo ana o ka unahiʻole, i 'ole ka palena iki mua o ka heluhelu, ka wā e kamailio e pili ana i ka mīkini voltmeter. Inā ka mea hoʻohana ua loaa i kekahi ao manaʻo no ana anakahi uila, hiki e hou i ka mea ma luna o aiaiiuo mawaho me ka i ia mea hiki ke hana, no ka laʻana, he, ia'ku, ka mahana, a me ka papa koa, a me ka alapine hewa lepa no aiaiiuo.

rula o ka hana

General noaia o functioning o ka mea i loa kalele iho ma luna o ka manaʻo. Inā keia mea i ka electromechanical voltmeter i kaʻume mākenēki nenoaiu, ka 'ikepili i kaʻikena pele. Ke kaumaha ma muli kona nui, a me maoli ka haiahū kūmau laʻau kuhikuhi pua mechanically hui me ka huakai kaapuni haka ai 'ole kekahi mea'ē aʻe i ka mea i hoʻohana' ia, e hoohuli i ka pono ma ka huakai kaapuni. I ka pololei o ia mau mea i mea ole loa nui, no ka mea, aole ia e ae e loaa kiʻekiʻe aiee o ka hoʻokomo o resistors, a nolaila ka poʻea pau nui ei ana, mahope mai o ka parasitic conductivity ua hou i ka huakai kaapuni.

Common i ka makahiki hou ma ka kikohoʻe voltmeters i ka nui helu o ka hale uilaʻoe ma lalo o ka hewa. O ke kumu ho i ka huli ana o ka mea like neaiaea hua mai la i ka hoʻokomo o maʻi, i loko o ka mīkini palapala ka hoʻohana 'ana i ka ADC. Kēia mea maoli hana hoihoi, Ua loaʻa i ka hailona o ka moʻokalaleo ma luna o ke kumuhana. Oia ka voltmeter, ke kumukuai o ka i loli aʻe, mai kekahi mau haneri rubles, o ka papa, i manao ia e ka waiwai koho o ka manawa a me ka nui pololei, nae, ia mea hiki ke piha ana i ke anakahi uila ma na maʻi o ke kaʻa o na pu ki a 220 V. Panel

Ai pili aku i ka huakai kaapuni

Ke voltmeter kaapuni ua mau pili laua a hiki i ka haawe a me ka mana kumu, ina he mea pono, e ana i ka electromotive ikaika a me ka maʻi anakahi uila. I mea no ke aha ka mea, he ikaika e pono ai no ka hoʻokomo o ia'ku o ka mea, no ka mea, he pili ia kuhi i keʻano o ka hou conduction i loko o ka huakai kaapuni.

Ma kekahi hihia, mai i hoʻohui i ka voltmeter, ke kumukuai o ka i ana ma kekahi aoao, he nui, ma ka huakai kaapuni ma ka hopena ua. I ole ia ka mea hoʻohana holo i ka pilikia o corny kuni i ka noiʻi, a me ka ole ka manawa e loaʻa mai i na mea no i na mea a pau i ka hoʻomaka 'ana. Inā hiki ina ke ku nei he barbaric hoopii, me kona hoike e ole e hilinai ai, no ka mea, o ka pono ma ka huakai kaapuni ua undergoing nui loli ma keia pili i ka voltmeter, hou e hookuke i loko o ka ike ole paha, e aʻo i ka maoli anakahi uila kahi ma i ana i hana ai.

lawelawe mālama nui

Mai ka ia'ku o ka voltmeter i loko o ka hapanui hihia i lawa ka nui a me ka pilina kiʻikuhi, niioaaonoaaiii, hoʻohana 'ia i loko o laua, o ka pilikia o ka noho he nui uila nń i loko o ka haʻahaʻa anakahi uila huakai kaapuni i ka palena haʻahaʻa. Naʻe, i ka wa e kamailio ana hanalima manaʻo, pakahi aku la ia i loko o ka haka mana, e komo ai, alahula anaia mai Hawaiʻi me ke anakahi uila, a ua hoʻoneʻe 'ia paha ke au paialewa. Nolaila, he pono e maluhia ma waena o nā kulanui, a me ka lawa ka ike, laholio Loan, moena a me nā kūpono mea, o ka papa, ua contraindicated kekahi ha awina. He aha ana ka voltmeter hoʻoneʻe 'ia paha ia e loa weliweli no ke ola, no laila mākou e waiho aku,ʻaʻole e hoao aku i ka make. Ma kekahi hihia e hoopa aku i ka hanau kaula, a hiki ina ka haʻahaʻa-anakahi uila kaapuni, ma ka ho'ākāka 'ana, hana ole.

ka hopena

Ke paneʻana i ka ninau e pili ana i mea ana i ka voltmeter, nānā mākou i loko o mau hua'ōlelo kona 'ole, ka papa kuhikuhiE oaoieei-ano, Mea Maluna. O ka holo ana, i kēia manawa pōkole hōʻuluʻulu manaʻo 'aʻole i koi ae i ka hulina completeness, o ka oi aku ma haʻahaʻa dala o ka walaʻauʻana ike o ka uila' enekinia, i ka mea heluhelu.

Summing mai, ka mea e e kaulana i ka voltmeter ana, o ka papa, ke anakahi uila ma luna o ka huakai kaapuni hapa ia i ka mea, ua pili i loko o laua. I ole ia, i kona hoike makemake e unreliable,ʻaʻole e hōʻike i ka pilikia o ka hiki lilo o ka pipiʻi lako a pan. Ka mea heluhelu e e akahele ka wā hoʻohana 'ana i ka mea hāpai mīkini i loko o ka hale, no ka mea, o ka hui' ana me kiʻekiʻe-anakahi uila kaapuni mau mea pilikia loa ke ola.
