Jenereta ndi chipangizo chomwe chimasintha mphamvu zama makina ozungulira kukhala magetsi. Majenereta a Asynchronous amagwiritsa ntchito mfundo zamakina opangira ma induction kuti asinthe mphamvu ya kinetic kuchokera ku maginito osuntha ndi ma coil, omwe amalumikizidwa ndi mawilo a waya wamkuwa pakatikati pachitsulo, kukhala voteji yamagetsi kenako kusinthasintha kwamagetsi pazida zam'nyumba kapena mafakitale.
Dongosolo lopangira ma asynchronous AC limaphatikizapo zigawo zazikulu zitatu: rotor (gawo lozungulira), stator (magawo osasunthika a ma conductor) okhala ndi maginito ozungulira mozungulira kuti asayime mogwirizana ndi ozungulira; Magawo a electromagnetic opangidwa m'zigawozi amachititsa mafunde a mawaya omwe amazungulira mozungulira iwo akamadutsa m'maderawa chifukwa cha kusintha kwawo komwe kumayendera.
Mu positi iyi tikambirana:
- Kodi jenereta induction imagwira ntchito bwanji?
- Kodi pali kusiyana kotani pakati pa synchronous ndi induction jenereta?
- Kodi kuipa kwa jenereta induction ndi chiyani?
- Kodi jenereta yopangira induction ndi jenereta yodziyambitsa yokha?
- Kodi ndichifukwa chiyani makina olowetsa induction sagwiritsidwa ntchito ngati jenereta?
- Kodi makina olowetsa induction angagwiritsidwe ntchito ngati jenereta pamtundu wanji?
- Chifukwa chiyani injini yolowera siimatha kuthamanga mwachangu?
Kodi jenereta induction imagwira ntchito bwanji?
Mphamvu ya jenereta yolowetsa imapangidwa kuchokera ku kusiyana kwa liwiro lozungulira pakati pa rotor ndi stator. Pogwira ntchito bwino, minda yozungulira ya injini imazungulira pa liwiro lalikulu kuposa ma koyilo awo kuti apange magetsi. Izi zimapanga maginito maginito ndi polarities zosiyana zomwe zimapanga mafunde omwe amatulutsa kasinthasintha kwambiri mbali zonse ziwiri - mbali imodzi imapanga magetsi pamene ina imawonjezera torque yoyambira mpaka ifike pa liwiro lofananira pomwe padzakhala mphamvu zokwanira zotulutsa zonse popanda cholowa chilichonse. mphamvu zofunika!
Kodi pali kusiyana kotani pakati pa synchronous ndi induction jenereta?
Majenereta a synchronous amapanga magetsi omwe amalumikizidwa ndi liwiro la rotor. Komano, majenereta olowetsamo amatenga mphamvu kuchokera ku gridi yamagetsi yakudera lanu kuti asangalatse minda yawo ndikupanga magetsi - motero amazindikira kwambiri kusintha kwa ma frequency olowera kuposa momwe majenereta amachitira!
Kodi kuipa kwa jenereta induction ndi chiyani?
Majenereta a induction sagwiritsidwa ntchito nthawi zambiri pamakina amagetsi chifukwa ali ndi zovuta zingapo. Mwachitsanzo, sikoyenera ntchito yosiyana, yokhayokha; jenereta amadya m'malo kupereka magnetizing KVAR amene kusiya zambiri kuchitidwa ndi majenereta synchronous ndi capacitors; ndipo pomaliza kulowetsako sikungathandize pakusunga ma voltages amtundu monga mitundu ina ya mayunitsi opangira.
Kodi jenereta yopangira induction ndi jenereta yodziyambitsa yokha?
Majenereta a induction sizomwe zimayambira zokha. Amatha kungoyendetsa zozungulira zawo pomwe akugwira ntchito ngati jenereta. Makinawa akamagwira ntchito imeneyi, amatenga mphamvu yochokera ku mzere wa AC ndikutulutsa mphamvu yobwereranso muwaya wamoyo!
Werenganinso: mitundu ya zida lalikulu mwina simumadziwa
Kodi ndichifukwa chiyani makina olowetsa induction sagwiritsidwa ntchito ngati jenereta?
Makina opangira ma induction sagwiritsidwa ntchito ngati jenereta chifukwa cha kupezeka kwa majenereta olumikizana ndi ma alternators. Ma SG amatha kupanga mphamvu zogwira ntchito komanso mphamvu zogwira ntchito, pomwe ma IG amangotulutsa mphamvu zogwira ntchito pomwe akugwiritsa ntchito mphamvu zokhazikika. Izi zikutanthauza kuti IG iyenera kukhala yokulirapo kuposa momwe imafunikira kuti ikwaniritse zofunikira zake zomwe zitha kukhala zokwera mtengo kwambiri chifukwa cha kuchepa kwake.
Kodi makina olowetsa induction angagwiritsidwe ntchito ngati jenereta pamtundu wanji?
Ma motors induction amatha kutulutsa mphamvu ngati ma jenereta pomwe liwiro la choyendetsa chachikulu lili pa liwiro lofananira koma osati pamwamba pake. Mfundo yayikulu yopangira magetsi ndi injini yolowera imakhala ndi ma frequency a resonant, ndipo kuti mupange ma frequency amenewo mumafunika zambiri kuposa makina opangira okha. Mukamagwiritsa ntchito jenereta iyi moyenera, kulumikizana kuyenera kuchitika pakati pa zidutswa ziwirizo zonse zimakhala ndi gawo lawo lozungulira la ma elekitiromu kuti aziyenda limodzi ngati gawo limodzi.
Kodi Induction Motor imagwira ntchito bwanji ngati Jenereta? Monga tanenera kale, ngati palibe katundu wakunja wolumikizidwa ndiye kuti panopa ikuyenda momasuka kudutsa dera lililonse lokhala ndi inductive impedance yokha - zomwe zikutanthauza kuti magetsi amadutsa akuyamba kukwera mpaka ma voltages otsiriza adutsa mizere iwiri kuchokera kugwero.
Chifukwa chiyani injini yolowera siimatha kuthamanga mwachangu?
Sizingatheke kuti injini yolowetsamo ikhale yothamanga kwambiri chifukwa katundu wake ayenera kugwiritsidwa ntchito nthawi zonse. Ngakhale popanda katundu, pangakhalebe kuwonongeka kwa mkuwa ndi mpweya chifukwa choyendetsa makina amphamvu ngati amenewa. Poganizira izi, kutsetsereka kwa mota sikungafike ziro
