Power dzakabatana. DC simba: chikwata

Power mu Physics zvinonzwisiswa sezvo reshiyo iri kuvakwa imwe nguva kushanda kusvikira nguva iyo iri rinoitwa. Under zvokuimba basa inomirira quantitative chezvinonhuwira matambudziko simba pamusoro muviri, nokuda iyo ekupedzisira inofamba muchadenga.

Unogona kuratidza simba uye sezvo mwero simba chinja. Kureva, zvinoratidza kuti kunyatsoshanda ari otomatiki muchina. Nokuyera simba zvinova pachena kuti basa riri kuitwa nokukurumidza.

Power chipimo chikwata

Power unotaurwa watts or kana joules por wechipiri. Vatyairi anozivikanwa simba kuyerwa mu horsepower. Nenzira, kusati kwatombova chiutsi injini kukosha ichi haina kuyerwa zvachose.

Rimwe zuva, vachishandisa mashandiro ari kwangu, injiniya George. White akatora kuvandudzika ake. Kuti aratidze injini ake kuvandudzwa akaenzanisa pamwe chokupika mabhiza. Vanhu vakashandisa navo kwemazana emakore. Naizvozvo munhu aiva nyore kufungidzira basa raidiwa mabhiza imwe nguva.

Pavanoona pavo, White akaenzanisa womuenzaniso chiutsi michini, zvichienderana uwandu horsepower. Iye experimentally akaverenga kuti rimwe bhiza simba riri 746 watts or. Nhasi, munhu wose chokwadi chokuti nhamba iri overpriced zvakajeka, asi simba chikwata vakasarudza kuchinja.

Kuburikidza akati chaiko kwazvo kudzidza kuita, sezvo anowedzera basa kunowedzera nokuti imwe nguva. munhu kwezvipimo chairema yakayerwa kwakadaro kwapararira chaizvo. It akatanga kushandiswa nenzira dzakasiyana-siyana zvigadziriswe. Saka, kunyange kana watts or uye zvave kwenguva refu, nokuti vazhinji horsepower zviri zvikuru zvinonzwisisika kupfuura vamwe simba dzakabatana.

How kunzwisisa simba mumhuri midziyo yemagetsi

Power Chokwadi, kunoratidza uye neimba magetsi michina. In mwenje vachishandisa zvakananga tsika dzayo, somuenzaniso makumi matanhatu watts or. Mabumba zhinji mwero simba kumisa kana hazvibviri, nekuti zvimwe vachava nokukurumidza kuipa. Asi kana iwe hauna kutenga chinhu incandescent rambi, uye akatungamirira kana fluorescent, vachakwanisa kuvhenekera rukuru nekupenya, apo unoparadza simba shoma.

simba rakawanda, Chokwadi, ndiyo Proportional kuti uwandu simba zvakananga. Naizvozvo, nokuti Vagadziri chiedza Mabumba anogara mumunda chigadzirwa kugadziriswa. Pari, vatengi vanosarudza vamwe nzira, kunze incandescent mwenje.

Sport simba

simba chipimo zvidzidzo zvinozivikanwa kwete chete maererano nokushandiswa zvigadziriswe. Pfungwa simba kunogona kunzi mhuka uye vanhu. Somuenzaniso, ukoshi ichi inogona dzaona kana mutambi kanoita bhora kana zvimwe zvinoshandiswa kuti varuwane somugumisiro pokugadzwa Zvakarurama simba, daro uye nguva kushandisirwa.

Unogona kunyange kushandisa zvirongwa kombiyuta nako indekisi rinowanikwa somugumisiro akaita zvimwe mari maekisesaizi uye pakatanga parameters.

kuyera nhumbi

Dynamometer - zano rinokosha naro simba kunoyerwa. Vanewo kushandiswa kuona simba uye torque. The Chishandiso rinoshandiswa nenzira dzakasiyana-siyana maindasitiri. Somuenzaniso, vanoratidza simba pamusoro injini. Kuti aite izvi, injini rinobviswa motokari uye zvakabatana kuti dynamometer. Asi pane namano kuti vanokwanisa kuverenga inodiwa kunyange napakati vhiri.

Mumitambo mushonga uye dynamometers zvakare zvakapararira. Simulators vanowanzova sensors zvine chokuita kuti kombiyuta. Navo, akaita zvose kuyerwa.

Wattage

James Watt akazogadzira hwemvura injini, uye kubvira 1889, chiyero simba remagetsi vakava watts or, uye international gadziriro yakayerwa ukoshi yaisanganisira muna 1960.

In watts or kuyerwa vamwe simba zvemagetsi asiwo chafariz, zvemaziso kana kwete chete. Zvinonzi zvakare kakawanda kuumbwa multiples uye Sub-multiples. Vanodanwa pamwe kuwedzera chepakutanga rokuti siyana prefixes "churu", "Mega" "giga", etc.:

• 1 kilowatt vakaenzana chiuru watts or;
• MW mamiriyoni 1 watts or vakaenzana uye zvichingodaro.

Kilowatt-awa

Munyika dzakawanda SI maitiro hakuna Kuyerwa dzakabatana akafanana kilowatt-awa. Nhamba iyi iri kunze hurongwa, akasuma azvidavirire nokuda ukapisa yemagetsi simba. In Russia nayo inoshanda pamwe GOST 8.417-2002 murau apo chikwata simba nokuyerwa remagetsi uye kushanda akasarudzwa zvakananga.

chikwata ichi pachii kunyoresa kuparadzwa yemagetsi simba. Ndicho zvikuru yokuita chimiro, izvo zvibereko zvinogamuchirwa zvabuda. Multiples pano kunogona kushandiswa kana zvakakodzera. Vanotarisira zvakafanana watts or:

• 1 kilowatt awa ndiyo 1000 zvatinoita mazuva ese zvive;
• 1 megawatt-awa vakaenzana 1,000 kilowatt-awa, uye zvichingodaro.

zita Full kuchinzi, sezvo atoona, ane hyphen, uye pfupi - kuburikidza pfungwa (zvatinoita mazuva ese zvive, kWh).

Sezvinoratidzwa magetsi simba

Vazhinji vakabvuma kuratidza akati paakati zvakananga pamusoro dzimba electric chokushandisa. mazita zvinobvira:

• watt uye kilowatt;
• Zvatinoita mazuva ese zvive uye kilowatt-awa;
• Volt-Amps uye kVA.

Chinonyanya chiratidzo yezvisikwa kushandiswa vezvikwata zvakadai watts or kana kilowatts. Kana unogona kuitwa musi chikwata rakagumisa kuti simba iri mune midziyo iyi.

Kazhinji watts or uye kilowatts akayera zvokuimba simba dzemagetsi emagetsi uye Motors, chafariz simba dzemagetsi Heaters uye zvichingodaro. D. kunoreva kunyanya kuitika simba dzaishandiswa mune mudziyo riri aisimbirira uwandu vanowanika kupisa, uye Masvomhu vari kufungwa kare vanomutevera.

Watt-kwemaawa uye kilowatt-awa vanoratidza simba kudyiwa kuti kupiwa chairema nguva. Kazhinji mazita aya anogona kuonekwa mumhuri midziyo yemagetsi.

Munyika dzakawanda SI maitiro ane magetsi simba zviyero, izvo yakaenzana watts or uye kilowatts - a volt-amperes uye KVA. chipimo kwakadaro anopa kuverenga AC simba. Ivo zvinoshandiswa hwokugadzira Masvomhu apo zvinokosha magetsi parameters.

rokuti kwakadaro zvakanakisisa zvinonyatsoenderana zvinodiwa magetsi engineering, apo namano anoshanda rakatumbuka ano, vari vaviri vanoshingaira uye reactive simba. Naizvozvo, Magetsi riri pakutsvaga mubatanidzwa yenhengo izvi. Kazhinji VA anoratidza simba mano zvakadai transformers, inductors, uye dzimwe converters.

Panguva mugadziri Anosarudza izvo zviumbu yakayerwa kuti zvakanyatsonanga nayo, kunyanya panyaya yakaderera-simba midziyo (uyo vari Somuenzaniso, mhuri midziyo yemagetsi), mazita ose matatu zvinoodza rienderane.
