Kukarukureta simba magetsi nematunhu

Chero zvemagetsi mudziyo dzinoratidzwa akawanda zvinokosha parameters, ramakagadzwa yavose sezvavakatarirwa voltage, kuitika uye simba. Dzimwe humboo jira yakati simba uye voltage, magetsi ari iyi iri nyore kuwanikwa tichishandisa anozivikanwa Masvomhu Ohm kwakaita (Chokwadi, vakawanda Reservations - semuenzaniso, inofanira kuzivikanwa Kosi). Neizvi ndezvechokwadiwo: nokuziva kuitika uye voltage, zvinokwanisika kuita simba kukarukureta. The pose rezvebonde ine mashoko akawanda pamusoro penyaya, asi vakawanda vavo vari dzaizopiwa unyanzvi.

Ngatitarisei chii chinorehwa nemashoko okuti "Magetsi", chii ayo mhando uye sei kuti simba kukarukureta. Mumuviri pfungwa simba anoratidza sei kutsanya yokugadza (mudziyo) simba kutendeuka kunoitika imwe kana imwe nzira anobatsira basa. Ndizvo nyore! rokuti "mutambo" ingangodaro kushandisa chete vasiri magetsi namano.

The zvemagetsi Kuparadzana kushandisa, maererano izvo pane chinoshingaira uye reactive simba. The rokutanga anotendeuka zvakananga kunyika chinobatsira basa, saka, riri kuonekwa rakakura. The chikwata chiri W uye nomukaka -. Kilowatt, Megawatt etc. nayo kunoratidzwa nemhuri midziyo yemagetsi. Kunyange zvazvo izvi hazvirevi kuti hapana reactive zvinoriumba. Uyewo, wechipiri - ane chisingadiwi, sezvo Implementation basa asingatakuri chikamu, uye yakawandisa-siyana nazvo. Akayera "gat" (volt ampere reactive) uye nomukaka - kilovolt-ampere reactive etc. Huwandu vanoshingaira uye reactive zvinoriumba dzinoumba simba rakakwana (volt-amperes VA).

Muenzaniso unoshamisa inodzidzisa pamwe yakachena resistive mutoro - wemagetsi hita. Kana nepariri magetsi ari kunotangira kuchipisa, uye maererano. Saizvozvowo, mabasa reactive simba nevatengi - munhu chaiwo transformer. Kana basa rake muna windings pave remagineti iyo pachayo haina zvakafanira (kushandisa remagetsi induction pfuma). The rinobva Musimboti iri magnetized, kurasikirwa kuitika. Nemamwe mashoko:

Q = U ini chivi Fi,

apo chivi Fi - Sine of pakona pakati ano uye voltage. chiratidzo chacho kunoenderana hunhu mitoro (capacitive kana inductive).

simba kukarukureta kunotanga Pakusarudza ano mhando: kugara kana shanduka, sezvo Masvomhu havasi nokudenga.

Muchiitiko chokutanga, migumisiro mutemo dzenhoroondo Ohm wacho. Power P ndiyo zvibereko ano I panguva voltage U:

P = ini U (W = A * B).

Apo redunhu kuti simba bhuku riri kufungwa vatungamirire EMF: zvakakodzera kuti kuverenga pakati kunobva impedance. Nokudaro, jenareta kana bhatiri umo magetsi ichibva "-" kuti "+", achipa simba kuti mutoro redunhu, anotumira simba. Kana pari kubuda ari chakatarisana vakashandisa mukana (bhatiri uchiraira), ipapo simba Absorção de Água emf kunobva.

Power kukarukureta fomura kuti ive AC (cheni chete-danho) Nhoroondo coefficient - "simba chinhu." Zvinomirira vanoshingaira simba chezvinonhuwira nhamba kusvikira nhamba. Zviripachena, kuna Tan cosine akaenzana 1 (akakwana), sezvo pasina reactive zvinoriumba. Zvikasadaro, kuderedza Kurasikirwa ari jenareta divi yokushandisa siyana kuwedzera majoini kana zvimwe rwokugadzira mhinduro.

Saka:

P = U ini Kosi Fi.

Kukarukureta simba -danho matatu nematunhu rinoitwa mumwe chokutambudzika, uye zvichiguma tsika ipapo inobatanidzwa. AC pachena simba rinowanikwa sezvo yaiungana mudzi pakati vakaverenga dzaiungana vanoshingaira uye reactive zvinoriumba. Nokuti generating mano (substation) kukosha kuziva chaizvoizvo zvizere chinzvimbo, sezvo vanosarudzwa pamusana ichi, nezvimwe zvinhu zvose kutevera ngetani. Zviri pachena kuti mune Kazhinji hazvibviri kuziva pachine yezvakaita mutoro.
