Okokuqala, izinga lomthwalo wemoto liphantsi.Ngenxa yokhetho olungafanelekanga lwemoto, intsalela egqithisileyo okanye utshintsho kwinkqubo yokuvelisa, owona msebenzi wemoto ungaphantsi kakhulu kunomthwalo olinganisiweyo, kunye nemoto ethatha malunga ne-30% ukuya kwi-40% yomthamo ofakiweyo. phantsi komthwalo olinganisiweyo we-30% ukuya kwi-50%.Ukusebenza kuphantsi kakhulu.

Okwesibini, i-voltage yonikezelo lwamandla i-asymmetric okanye i-voltage iphantsi kakhulu.Ngenxa yokungalungelelani komthwalo wesigaba esinye sesigaba sesithathu sombane esine-voltage esine-voltage system, i-voltage yesigaba sesithathu se-motor i-asymmetrical, kwaye i-motor ivelisa i-torque yokulandelelana kakubi.Ilahleko ekusebenzeni kweenjini ezinkulu.Ukongeza, i-voltage yegridi iphantsi ixesha elide, okwenza ukuba i-motor yangoku ekusebenzeni okuqhelekileyo ibe nkulu kakhulu, ngoko ke ilahleko iyanda.I-voltage enkulu ye-asymmetry yesigaba sesithathu, i-voltage ephantsi, ilahleko enkulu.

Eyesithathu kukuba iinjini ezindala nezindala (eziphelelwe lixesha) zisasetyenziswa.Ezi njini zisebenzisa i-insulation ye-class E, zinkulu, zinesiqalo esibi, kwaye azisebenzi kakuhle.Nangona sele ineminyaka ilungiswa, isasetyenziswa kwiindawo ezininzi.

Okwesine, ulawulo olulambathayo lwesondlo.Ezinye iiyunithi azigcini ii-motor kunye nezixhobo njengoko zifunwa, kwaye zivumela ukuba ziqhube ixesha elide, okwenza ukuba ilahleko iqhubeke ikhula.

Ke ngoko, ngokujonga koku kusetyenzwa kokusetyenziswa kwamandla, kuyafaneleka ukufunda ukuba yeyiphi na inkqubo yokonga umbane oza kuyikhetha.

Kukho malunga neentlobo ezisixhenxe zezisombululo zokonga amandla kwiinjini:

1. Khetha injini yokonga amandla

Xa kuthelekiswa neenjini eziqhelekileyo, i-motor esebenza kakuhle kakhulu ikhulisa uyilo lulonke, ikhetha i-high-high windings yobhedu kunye ne-silicon sheet sheets, inciphisa ilahleko eyahlukeneyo, inciphisa ilahleko nge-20% ~ 30%, kwaye iphucula ukusebenza kakuhle nge-2% ~ 7%;ixesha payback Ngokuqhelekileyo 1-2 iminyaka, ezinye iinyanga.Xa kuthelekiswa, i-motor esebenza kakuhle yi-0.413% ngaphezulu kwe-J02 ye-motor series.Ke ngoko, kunyanzelekile ukuba kuthathelwe indawo iinjini zombane ezindala ngeenjini zombane ezisebenza kakuhle kakhulu.

2. Ukhetho olufanelekileyo lwamandla emoto ukufezekisa ukonga amandla

Urhulumente wenze le migaqo ilandelayo kwiindawo ezintathu zokusebenza ze-asynchronous motors zesigaba sesithathu: indawo yokusebenza kwezoqoqosho iphakathi kwe-70% kunye ne-100% yezinga lomthwalo;indawo yokusebenza ngokubanzi iphakathi kwe-40% kunye ne-70% yezinga lomthwalo;izinga lomthwalo ngama-40% Ezi zilandelayo ziindawo zokusebenza ezingezizo ezoqoqosho.Ukukhetha okungafanelekanga komthamo wemoto ngokuqinisekileyo kuya kubangela inkcitho yamandla ombane.Ke ngoko, ukusebenzisa imotor efanelekileyo ukuphucula amandla kunye nesantya somthwalo kunokunciphisa ukulahleka kwamandla kunye nokonga amandla.

3. Sebenzisa imagnethi slot wedge endaweni yentsusa slot wedge

4. Yamkela iY/△ isixhobo sokuguqula ngokuzenzekelayo

Ukuze kulungiswe inkunkuma yamandla ombane xa isixhobo silayishwa kancinci, kwindawo yokungatshintshwa kwemoto, iY/△ isixhobo sokuguqula ngokuzenzekelayo singasetyenziselwa ukufezekisa injongo yokonga umbane.Ngenxa yokuba kwisigaba sesithathu segridi yamandla e-AC, i-voltage efunyenwe ngoxhulumaniso olwahlukileyo lomthwalo ihluke, ngoko ke amandla athathwe kwigridi yamandla ahluke.

5. Motor amandla factor reactive amandla imbuyekezo

Ukuphucula into yamandla kunye nokunciphisa ilahleko yamandla zezona njongo zembuyekezo yamandla asebenzayo.Umba wamandla ulingana nomlinganiselo wamandla asebenzayo kumandla abonakalayo.Ngokwesiqhelo, amandla aphantsi aya kubangela umsinga ogqithisileyo.Ngomthwalo onikiweyo, xa i-voltage yonikezelo ihlala rhoqo, i-factor factor ephantsi, inkulu ikhoyo ngoku.Ngoko ke, amandla ombane aphezulu kangangoko kunokwenzeka ukugcina amandla ombane.

6. Ulawulo lwesantya soguqulo rhoqo

7. Ulawulo lwesantya solwelo lwemoto ejijayo
