Electricity. simba razvino

Kudzidza magetsi ari panyama chakajairika kunotanga kunyange kuchikoro. vadzidzisi vazhinji, vadzidzi kurerutsa kunzwisisa zvinhu, vachienzaniswa kushandisa magetsi ari muitisi pamwe kufamba mvura kuburikidza nomutopota. Kunyange zvazvo nezvemuenzaniso uyu anofungidzirwa schematically achiri anokwanisa kutsanangura pezvakaitwa chokuita Chiitiko kuti magetsi vakawanda uye Magetsi kuyerera kondakita zvikuru. Asi, sezvo tsika inoratidza zviri nyore zvikuru kudzidza dzi uye outs chino guru wefizikisi, kana iwe chete funga chaiko pezvakaitwa kuitika pasina kuedza kuwana ishamwari yavo munyika zvemaziso mananara.

Kutsanangura zvemagetsi mananara kuitika conductors, shandisa zvakasiyana akagadzirwa variables uye parameters. Chokwadi, nokuti kushanda tiri hanya magetsi simba ano, asi Kutsunga parameter ichi uchasangana dzimwe chikuru zvechadenga aibuda magetsi ari kondakita.

The simba ndechimwe zvinokosha zvinoitwa magetsi. By nezvavanenge pfungwa zvinoratidza uwandu magetsi (uwandu muripo), yemagetsi redunhu iyo inopfuura vari chikwata nguva. To izvi kufungwa nhamba yemabhuku yemagetsi vebasa iyo vakayambuka muchinjikwa chikamu chete chikwata nguva. In kwemasvomhu chimiro, ukoshi ichi rinowanikwa somunhu pendant (Cl) akakamurwa yechipiri (s). Nokuti mumwe ano chipimo akatorwa nokukura ampere (A).

Rinotevera parameter kuti rakundwa paunoronga pakuverenga kuitika simba voltage iri. Yandakapiwa Magetsi - ndicho yakarongeka kufamba nezvimedu kuva mutariri kuumba sangano zvakakodzera kuti yemagetsi munda. Saka voltage vasabatwa ukoshi rinowanikwa nhamba magetsi kushanda musi imwe chikamu cheni mhosva inoyerera napo. The chairema voltage, kwakasarudzwa kutora volts (V), rinova nhamba chairema basa panyama paminiti chikwata mutariri J. Cl.

Kushandisa Pepa ammeter chokuita mudunhu iri series, kuona kukura simba ano, uye voltmeter kwakabatana munguva yakafanana - voltage. AC simba zvino vakatsunga analytically kupfurikidza vachiwedzera zvainoita voltage. Tichitarisa kare kugamuchira wenyama parameter kusarudza kuwana simba chikwata J / s kana mumwe watt (W). In tsika, zvatakurukura muenzaniso kukarukureta iri nyaya yakanaka umo kutsunga DC simba.

Ndizvo kazhinji tsika kwezuva nezuva tiri nevanhu-danho matatu iyezvino. We kuona simba vatatu-danho razvino sezvo chitsama kugona mumwe nomumwe kutotanga. Sezvo mumwe nomumwe wavo unoshanda AC rudzi, simba chinhu kukarukureta inowedzerwa mutoro simba chinokonzera Kosi j.

Kufunga zvachose ano tichikwanisa dzakasiyana nzira unobatanidza mutoro tiri-danho matatu kuitika (uye tinoziva pane vaviri - Triangle uye nyeredzi), tinoona kuti pashure nyore kwemasvomhu kushanduka payakavakirwa nokuti kukarukureta vacho vakatora imwe maonero. To zvinobikwa voltage simba mutsetse uno uye nesimba chinhu Kosi J -bereka mutoro chakaita akaenzana mativi pamudzi nhatu (kana, mune imwe anofungidzirwa kukarukureta 1,73).

Aongorora pfungwa "simba pfungwa" zvinofanira kuyeuchidzwa kuti pane mhando mbiri chikuru nayo. Nokuti rinoita simba magetsi hwokuratidza kutendeuka kupinda dzimwe mhando simba. Zvinogona chiedza, chafariz, zvemaziso uye nevamwe. Kushandiswa kuyera watts or, kilowatts, megawatts.

Kana kukurukura reactive Magetsi kunoreva kukosha, ichazivikanwa noku zvemagetsi mutoro, simba akasikwa vibrations ari remagetsi zvesango vatengi. Kazhinji, kwakadai simba runozivisa injini. Sezvo vezvikwata tora volts - amperes reactive (hadde).
