Ndechipi zvinoshingaira uye reactive simba?

Kukarukureta of zvemagetsi simba anoshandiswa maindasitiri kana mhuri zvemagetsi mudziyo inowanzopiwa kuitwa pamwe zvizere simba yemagetsi anoshandiswa ruchiyerera napakati akayera remudunhu. Muchiitiko ichi pane vaviri indekisi tichiratidza yose simba mutengo pa basa nevatengi. Uhu huwandu dzinonzi rinoita uye reactive simba. Zvachose simba pakuverengwa idzi parameters maviri. Chokwadi kuti simba rinoita uye reactive kwakadaro uye sei kuongorora uwandu Billing, tichaedza kutsanangura munyaya ino.

simba rizere

Maererano isingachinji tsika, vatengi vanobhadhara hapana mambure simba, iyo inoshandiswa zvakananga upfumi, uye azere, iyo inotiita vachida Provider. Kusiyanisa nhamba idzi nokuda vezvikwata yakayerwa - yose simba unotaurwa volt-amperes (VA), uye anobatsira - mune kilowatts. Active uye reactive simba anoshandiswa zvose kwakapa kubva magetsi network.

rinoita simba

The kushingaira chezvinonhuwira yose simba anoita rinobatsira basa uye vakatendeutswa kune mhando simba kuti zvinokosha kuti mutengi. A nhengo dzeimba uye maindasitiri midziyo dzemaitirwe kuti basa uye pachena simba ndiwo chete. Pakati mano dzakadaro - dzemagetsi cookers, chiedza Mabumba, yemagetsi, Heaters, simbi uye ironing nemichina uye zvichingodaro.

Kana pasipoti rine vanoshingaira simba 1 KW, zvachose simba zano rakadaro achava 1 kVA.

Pfungwa reactive simba

mhando iyi simba tinoberekwa namaketani, sorutivi izvo pane reactive okunze. Reactive simba - chikamu zvizere vachikwanisa kuita, usina kupedzerwa anobatsira basa.

Electric redunhu DC pfungwa pamusoro reactive simba vasipo. Maketani AC reactive zvinoriumba rinowanikwa chete zvakaitika apo pane inductive kana capacitive mutoro. Muchiitiko ichi pane kusawirirana mune ano chokutambudzika kusvika voltage danho. Izvi danho kuchinja pakati voltage uye iyezvino runotaurwa «φ» hunhu.

With inductive mutoro lag danho aona mudunhu iri capacitive - ayo kufanoronga. Saka, mutengi anouya chete chikamu zvachose kugona huru nezvinhu inokonzerwa asingabatsiri kudziyisa mano uye midziyo yemagetsi iri kushandiswa.

Power Nokurasikirwa kuitika nokuda pamberi magetsi mano inductive Coils uye capacitors. Nokuda kwavo, vari mudunhu kwechinguva kune kuunganidza magetsi. Zvadaro, zvakachengetwa simba iri zvokudya kunyika remudunhu. By mudziyo, sezvo chikamu nesimba kudyiwa iyo ine reactive chezvinonhuwira yemagetsi simba, muri inotakurika yemagetsi, dzemagetsi Motors uye siyana neimba midziyo yemagetsi. ukoshi ichi rinowanikwa kufungisisa zvikuru simba chinhu, iro runotaurwa sezvo Kosi φ.

Kukarukureta kuti reactive simba

Power chikonzero iri zvinobva 0.5 kusvika 0,9; chaiwo kukosha parameter ichi chinogona kuwanika pasipoti yacho mudziyo. Full simba ndiko kutsunga sezvakaita quotient kugovera basa simba nokuda coefficient.

Somuenzaniso, kana pasipoti ine wemagetsi chibooreso simba 600 W uye mutengo 0,6, ipapo zvachose simba ufungisise mudziyo akaenzana 600/06, i.e. 1000 VA. Pasina mapasipoti kuti kadambari chikwata zvachose simba reshiyo anogona kutorwa 0,7.

Sezvo mumwe chikuru mabasa aripo simba romugove gadziriro ndiko chokuendesa anobatsira simba kusvika pakuguma User, kuti reactive simba Nokurasikirwa vanoonekwa kuva akaipa chinokosha, uye kuwedzera nhamba iyi zvinoda kupinda mubvunzo kubudirira zvemagetsi Dunhu rose. Pakuenzanisa vanoshingaira uye reactive simba mudunhu inogona yakanyatsotsanangura kumiririrwa muchimiro ane varaidza mufananidzo:

The kukosha coefficient kuti kufirwa vakanyorwa

The yakakwirira nesimba chinhu muduku uchava Nokurasikirwa ose basa simba - uye nokudaro chikuru nevatengi mutengo wemagetsi simba rakawanda zvishoma isingadhuri. Kuti vawedzere kukosha coefficient izvi zvemagetsi anoshandisa siyana muripo mitoo nontarget simba varasikirwa. Compensating mudziyo muri emagetsi outstripping kuitika rimire Pasika angled pakati kuitika uye voltage. Nechikonzero ichochi, dzimwe nguva anoshandiswa capacitor kubhengi. Ivo zvakabatana muna zvakafanana nokushanda redunhu uye kushandiswa synchronous compensators.

Pakuverenga mari magetsi kuti private vatengi

Nokuti mumwe nomumwe kushandiswa vanoshingaira uye reactive simba ari munhoroondo hauna vaiita - musi rapanzvimbo kudya mugove reactive simba yakaderera. Naizvozvo, pasiri vatengi panguva simba kunwa anosvika 63 A kubhadhara imwe bhiri, umo vose magetsi manwiro anoonekwa kuti tichishingaira. Zvimwe nezvinhu chuma kune reactive simba haasi oga dzinounzwa uye hazvibhadharwi.

Nekurangarira kuti reactive simba nokuda nemabhizimisi

Chimwe chinhu - makambani nemasangano. In nezvivakwa maindasitiri uye maindasitiri zvivako yakaiswa vazhinji magetsi, uye zvachose magetsi anopinda pane chinokosha chikamu simba ndege iyo inodiwa kuti nokushanda yemagetsi uye simba ra. Active uye reactive simba akapa nemakambani nemasangano vanoda zvakajeka kuparadzana uye imwe nzira muripo nokuti. The hwaro murau pamusoro zvebhizimisi-nokutengesa ukama uye magetsi magumo-vanoshandisa kuti nyaya chaiwo kondirakiti. Maererano nemitemo iri gwaro iri, sangano upise magetsi anopfuura 63 A, tinoda zano rinokosha kuti inopa kuverengwa nokuda reactive simba chizvidavirire uye muripo.
Network sangano anovamba pakaunda reactive simba uye mutariri iwe maererano uchapupu hwake.

Reactive simba chikonzero

Sezvambotaurwa, zvinoshingaira uye reactive Magetsi kuti bhiri nokuda dzinounzwa yoga mitsetse. Kana nhamba bhuku magetsi kuparadzwa reactive uye asingauyi kusapfuudza isingachinji ndozvakajairwa, ipapo muripo reactive simba hachiverengerwi. The reshiyo chakasimbiswa zvakasiyana, kunoreva mutengo raro 0,15. Above pachikumbaridzo ichi unoparadza zvebhizimisi mazano vatakuri compensating mudziyo.

Reactive simba mukuvaka mufurati

A chaiwo nevatengi dzemagetsi chiri furati ane chikuru fiyuzi dzemagetsi kuparadzwa zvinopfuura 63 A. Kana imba chete pokugara, mazai reactive simba zvichabviswa mhosva. Saka, kugara imwe furati ona uchiraira chete zvachose magetsi kusvitsa mumba ikozvino-nokutengesa. The chete murau zvinoshandawo dzimba cooperatives.

Zvimwe zviitiko rokuzvidavirira reactive simba

Pane nguva apo pane mukuru-simukai kuvaka uye masangano wezvokutengeserana, uye nemafurati. Electricity zvitengeswa mudzimba kwakadaro nokudzorwa yoga nemirayiro. Somuenzaniso, kuparadzana angava kukura mupenyu nzvimbo. Kana mune imwe imba mufurati masangano vezvokutengeserana kugara isingasviki pahafu kushandisika munharaunda, muripo reactive simba hachiverengerwi. Kana pachikumbaridzo kubva muzana iri kupfuura, saka pane muripo pakumanikidzwa reactive simba.

Mune zvimwe zviitiko, dzimba havasiyiwi kubva abhadhare reactive simba. Somuenzaniso, kana imba kubatana pfungwa akagadzawo anosimudza nokuda Apartments, uchiraira kuti kushandisa reactive simba akasiyana chete zvokushandisa ichi. Apartment varidzi dzichiri kubhadhara chete rinoita simba.

Tikaziva yezviri uye reactive simba runoita kuti zvakarurama ngaaverenge zvoupfumi mugumisiro kugadzwa siyana compensatory mano kuderedza Nokurasikirwa anokonzerwa reactive mutoro. Maererano nenhamba, mano aya kukubvumira kusimudza kukosha Kosi φ kubva 0,6 kusvika 0,97. Nokudaro kwaita compensating mudziyo anogona kuponesa kusvika chetatu magetsi yawapihwa kuti vatengi. A chinokosha rutapudzo nokupisa kurasikirwa kunowedzera upenyu midziyo uye michina panguva kugadzirwa nzvimbo uye anoderedza mari rakapera zvigadzirwa.
