Menene halayen mitoci masu canzawa?

The Motar mitar mitar ƙananan ƙarfin lantarkis samar daMotar LT SIMOsuna da halaye masu zuwa

1. Zane na lantarki: Don injinan asynchronous na yau da kullun, manyan sigogin aikin da aka yi la'akari yayin sake tsarawa sune iya yin kiba, fara aiki, inganci da yanayin wutar lantarki. Don masu amfani da mitar masu canzawa, tun da maɗaukaki mai mahimmanci ya bambanta da ƙarfin wutar lantarki, ana iya farawa kai tsaye lokacin da zamewa mai mahimmanci yana kusa da 1. Sabili da haka, ƙarfin yin amfani da kayan aiki da farawa ba sa buƙatar la'akari da yawa, kuma babban batun da za a warware shi ne yadda za a inganta haɓakar motsin motar zuwa abubuwan da ba na sinusoidal ba. Gabaɗaya hanyoyin sune kamar haka:

1) Rage juriya na stator da rotor kamar yadda zai yiwu.

Rage juriya na stator na iya rage ainihin asarar tagulla don rama karuwar asarar tagulla da aka yi ta hanyar jituwa mai girma.

2) Domin murkushe masu jituwa masu girma a halin yanzu, inductance na motar yana buƙatar haɓaka daidai. Duk da haka, girman amsawar ramin rotor, mafi girman tasirin fata, da asarar jan ƙarfe mai jituwa. Sabili da haka, girman reactance motsin motsin motar dole ne yayi la'akari da ma'anar madaidaicin impedance tsakanin iyakar ƙa'idodin saurin gudu.
3) Babban da'irar maganadisu na injin mitar mitar mai canzawa gabaɗaya an ƙirƙira shi don zama mara nauyi. Na farko, an yi la'akari da cewa babban tsari na jituwa zai zurfafa jikewa na da'irar maganadisu. Na biyu, an yi la'akari da cewa a ƙananan mita, ƙarfin wutar lantarki na inverter ya kamata a ƙara shi yadda ya kamata don ƙara ƙarfin fitarwa.

2. Tsarin tsari

Lokacin zayyana tsarin, babban abin la'akari shine tasirin halayen samar da wutar lantarki maras-sinusoidal akan tsarin insulation, rawar jiki, hanyar sanyaya amo da sauran bangarorin injin mitar mai canzawa. Gabaɗaya, ya kamata a kula da waɗannan batutuwa masu zuwa:

1) Matsayin insulation, gabaɗaya matakin F ko mafi girma, yana ƙarfafa rufin ƙasa da ƙarfin jujjuyawar waya, kuma musamman la'akari da ƙarfin rufin don jure wa ƙarfin lantarki.

2) Dominvibration da kuma matsalolin amo na mota, Ya kamata a yi la'akari da tsayin daka na kayan motsa jiki da kuma gaba ɗaya, kuma ya kamata a ƙara yawan mita na yanayi kamar yadda zai yiwu don kauce wa resonance tare da kowane motsi na karfi.

3) Hanyar sanyaya: Gabaɗaya, ana karɓar sanyaya iska mai tilastawa, wato, babban injin sanyaya injin yana motsa shi ta injin mai zaman kansa.

4) Matakan don hana shaft halin yanzu, ya kamata a dauki matakan rufewa don injinan da ke da karfin sama da 160KW. Yawanci, yana da sauƙi don samar da asymmetry na da'ira da kuma shaft current. Lokacin da aka haɗa na yanzu da wasu manyan abubuwan haɗin gwiwar ke haifarwa, ƙarfin shaft ɗin zai ƙaru sosai, yana haifar da lalacewa, don haka ana ɗaukar matakan rufewa gabaɗaya.

5) DominMotar mitar mitar wutar lantarki akai-akais, lokacin da gudun ya wuce 3000/min, ya kamata a yi amfani da man shafawa na musamman mai juriya mai zafi don rama yawan zafin jiki na ɗaki.
