Magwero a mphamvu ngati zamagetsi: malongosoledwe, mitundu ndi makhalidwe

Magwero a mphamvu ngati zamagetsi m'dera lililonse ndi kusiyana ndi njira zake kukonzekera. Choncho, madambo zopindulitsa kwa ntchito mphamvu mphepo kapena kuwatembenuza kutentha pambuyo mpweya mafuta kuyaka. Mu mapiri, pamene pali mtsinje, kumanga madamu ndi madzi akutulutsira turbines chiphona. Electromotive mphamvu opangidwa kulikonse chifukwa mphamvu zina zachilengedwe.

Kodi ogula mphamvu

Magwero a mphamvu ngati zamagetsi analandira pambuyo voteji akatembenuka mphepo mphamvu, gulu kayendedwe, madzi, chifukwa cha mchitidwe nyukiliya, kutentha kuyatsa gasi, mafuta kapena malasha. Ponseponse mphamvu zomera, opangira magetsi mphamvu okwerera. Pang'onopang'ono kuchepetsa chiwerengero cha zomera mphamvu za nyukiliya monga Sichanzeru kwathunthu anthu amene ali pafupi.

Thiabendazole angagwiritsidwe ntchito mankhwala anachita, izi zochitika timaona mabatire a magalimoto ndi zipangizo banja. Mabatire kwa mafoni ntchito pa mfundo yomweyo. Vetroviki ntchito mu malo ndi mphepo zonse pamene magwero magetsi ali ochiritsira kapangidwe mkulu mphamvu jenereta.

Zopangira mzinda wonse zina pasiteshoni ina sikokwanira, ndi magwero magetsi amaphatikizidwa. Choncho, pa madenga a nyumba m'mayiko ofunda anaika mapanelo dzuwa kuti kudyetsa zipinda payekha. Pang'onopang'ono, zachilengedwe magwero wochezeka lidzaloŵa m'malo siteshoni, kuipitsa m'mlengalenga.

m'galimoto

Battery zoyendera - si ndiyekhayo mphamvu zamagetsi. galimoto dera m'njira imene pamene anasamutsa ndondomeko ya kusintha mphamvu kayendedwe mu magetsi akuyamba. Ichi ndi chifukwa jenereta, ndi mmene kasinthasintha wa koyilo mwa munda maginito amalenga maonekedwe a mphamvu electromotive (EMF).

maukonde akuyamba kuyenda panopa nawuza batire, nthawi ya ntchito potsata capacitance ake. Adzapereke umayamba mwamsanga injini chiyambi. Ndiko kuti, mphamvu amapangidwa ndi moto mafuta. zochitika zaposachedwapa asiya galimoto ntchito EMF gwero la mphamvu ngati zamagetsi ku magalimoto.

Amphamvu magetsi mankhwala mabatire kubala ziliri pa dera chatsekedwa ndiponso kukhala gwero la mphamvu. Pano pali ndondomeko n'zosiyana: ndi EMF kwaiye mu coils a dongosolo galimoto imene imapangitsa gudumu sapota. Mafunde mu dera yachiwiri yaikulu njila mathamangitsidwe liwiro ndi galimoto kulemera.

Mfundo ntchito koyilo ndi maginito

Current likuyenderera mu koyilo amachititsa ndi alternating maginito kamwazi. Nayenso, ali pa maginito buoyancy, zomwe zimachititsa chimango ndi polarities awiri osiyana sangathenso maginito. Choncho, magetsi magwero mphamvu ndi likulu kayendedwe ka magalimoto.

The ndondomeko n'zosiyana, pamene chimango ndi maginito imazungulira mkati windings chifukwa cha mphamvu kayendedwe akhoza kutembenuka alternating maginito kamwazi mu koyilo EMF. Komanso, dera la wokwera owongolera voteji kuti kupereka chofunika zizindikiro okwanira. Malinga ndi mfundo imeneyi, iwo amapanga magetsi magetsi, zomera matenthedwe mphamvu.

EMF mu dera pamaoneka ochiritsira chatsekedwa dera. Lilili bola wochititsa ntchito kusiyana angathe. mphamvu Electromotive chofunika kufotokoza makhalidwe a gwero mphamvu. The tanthauzo thupi: EMF mu dera chatsekedwa amasankhidwa molingana ndi ntchito ya mphamvu zakunja ndi kayendedwe ka limodzi mlandu zabwino mwa thupi lonse la wochititsa lapansi.

Chilinganizo: E = Ine R - kukana imatengedwa wathunthu, kungomanga kulimbikira mkati mwa gwero mphamvu ndi kukana kuwonjezera gawo amadyetsedwa a dera la.

Yosaloledwa unsembe wa substations

kondakitala uliwonse womwe utuluke panopa amapanga minda magetsi. Mphamvu gwero ndi chopatsilira mafunde mu atomu. Padziko makhazikitsidwe zikuluzikulu substations kapena pafupi waika jenereta zimakhudza thanzi la munthu. Choncho, amayesetsa kuchepetsa pomanga pafupi ndi nyumba Atengedwa.

Pa mtunda atathana kuti zinthu zamagetsi, kupitirira zimene zamoyo ndi otetezeka anaika mlingo malamulo. Zoletsedwa yomanga substation mkulu-mphamvu pafupi nyumba ndi njira anthu. Wamphamvu unsembe ayenera asungika ndi gated pakhomo.

mizere High-voteji ali wokwera pamwamba nyumba ndi kuwapanga kupitirira midzi. Kuthetseratu chikoka mafunde mu atomu m'dera zogona zopangira magetsi anatseka earthed zowonetsera zitsulo. Pankhani losavuta, ndi mauna a waya.

mayunitsi pa miyezo

Aliyense gwero mphamvu ndi dera anafotokozedwa ndi ukulu wa mfundo kachulukidwe. Zimenezi zimatithandiza ntchito mapulani ndi mawerengedwe a katundu pansi zakudya zenizeni. Mayunitsi ndi cholukanalukana ndi malamulo.

Pakuti mfundo katundu mphamvu mayunitsi zotsatirazi anaika:

• Kukana: R - Ohms.
• EMF: E - V.
• Reactance ndi impedance: X ndi Z - ohms.
• Current: I - mikuza mawu.
• Voteji: U - V.
• Mphamvu: P - Watts.

Ntchito yomanga motsatizana ndi kufanana madera mphamvu

The mawerengedwe dera imavuta, ngati pawiri ntchito zopangira magetsi magetsi a mitundu yosiyanasiyana. N'komwe kulimbikira mkati mwa nthambi iliyonse ndi malangizo a panopa kudzera ochititsa lapansi. Pakuti aliyense muyeso wa EMF gwero payokha chofunika ndipo pomwepo kutsegula dera pa malo a batire ndi kuyeza angathe chipangizo chakudya - ndi voltmeter.

Chatsekedwa dera chipangizo adzakusonyezani ndi voteji dontho, lomwe lili ndi phindu ang'onoang'ono. nthawi zambiri amafuna magwero angapo kupeza mphamvu zomuthandiza. Malinga ntchito angagwiritse ntchito mitundu angapo polumikizana:

• Musamasinthesinthe. EMF gwero madera wina analemba. Choncho, pamene ntchito awiri mwadzina 2 Volt mabatire analandira polumikiza 4 V.
• Yomweyi. Mtundu wa gwero ntchito kuonjezera mphamvu, motero, pali nthawi yaitali zikugwira ntchito ku mabatire. EMF wadera pamene kugwirizana ngati sasintha ofanana mfundo mwadzina mabatire. Nkofunika kusunga polarity cha kugwirizana kwa.
• Tikaphatikiza kugwirizana kawirikawiri ntchito, komabe apo. Mawerengedwe a emf chotsatira amapangidwa kuti m'dera lililonse chatsekedwa. Pamafunika nkhani polarity wa panopa ndi malangizo a nthambi.

Ohms Mains

Kulimbikira mkati mwa mphamvu ya magetsi gwero ndi n'komwe kudziwa emf chotsatira. Ambiri, mphamvu electromotive masamu ndi chilinganizo E = Ine R + Ine r Mukhoza. Kodi R - fundo ogula ndi r Mukhoza - kukana mkati. Kugwa kwa voteji chomwecho kuchita masamu ndi anthu aone kuti pali zotsatirazi: U = E - Iri.

Panopa osefukira dera ndi masamu monga mwa chilamulo dera zonse Ohm akuti: I = E / (R + r Mukhoza). Internal kukana amatha kulimbikitsa mphamvu panopa. Popewa izi, anasankha gwero kwa katundu ndi ulamuliro zotsatirazi: mkati gwero kukana ayenera kukhala laling'ono kwambiri kuposa onse kukana wonse wa ogula. Ndiye kuganizira mtengo wake si chifukwa cha mphepete ka zolakwa.

Kodi kuyeza Ohms mains?

Popeza magwero ndi amalandira mphamvu ya magetsi tidzakwatulidwa anavomera, ndiye funso yomweyo lakuti: mmene kuyeza kukana mkati mwa gwero? Pambuyo ohm-mita si olumikizidwa kwa ojambula ndi zimphamvu kupezeka kwa iwo. Pofuna kuthetsa ntchito mozungulira njira readout - chofunika mfundo kwa zosintha zina: panopa ndi voteji. Yowerengera wapangidwa malinga ndi chilinganizo r Mukhoza = U / Ine, kumene U - ndi voteji dontho kudutsa kukana mkati, ndipo ine - panopa mu dera pansi pa katundu.

The voteji dontho chimaonekera mwachindunji ndi malo mphamvu zoyendetsera. Mu dera kudziwika chikugwirizana ndi resistor R. Isanafike miyezo mwadzina ayenera wolembedwa ndi voltmeter gwero la EMF mu dera lotseguka - E. Komanso, katundu chikugwirizana ndi kuliika kuwerenga - U magetsi. ndipo I. panopa

Chofunika voteji dontho kudutsa mkati kukana U = E - U kutentha. Chifukwa, kufunika r Mukhoza achiyesa mtengo = (E - U katundu.) / I.
