Kana tichienzanisa neMG set neIGBT, nei MG set iri nani kune power transformer tester? Ndivanaani vatengesi vakuru muChina nepasi rose?

Mubvunzo wako chaizvoizvo ihurukuro yehunyanzvi yechinyakare mupasi rekuyedza re transformer:

Seti yeMG (Motor-Generator) ichienzaniswa neIGBT / solid-state frequency converter (SFC).

 

Muchokwadi, mafekitori mazhinji makuru emagetsi-transformer achiri kuda maMG sets, kunyanya pakuyerwa kwevoltage induced uye kuyerwa kurasikirwa. Pasi apa pane kuenzanisa kunoshanda kunoshandiswa mumafekitori etransformer.

1. MG Set vs IGBT Power Supply yeTransformer Testing

 

Chinhu	Seti yeMG (Jenareta yeMota)	IGBT / Static Frequency Converter
Tekinoroji	Muchina unotenderera (jenareta remadhiraivha emota)	Inverter yemagetsi yemagetsi
Kugona kwesimba	Yakakura zvikuru (MVA dzakawanda dziri nyore)	Yakakura asi inodhura zvikuru uye ine simba guru
Mafungu	Wave ine sine yakachena kwazvo	Inogona kunge iine maharmoniki ekuchinja
Kugona kwepfupi-dunhu	Simba kwazvo	Zvishoma nezvishoma zvinokonzerwa nemagetsi
Kukwanisa kurodha zvakawandisa	Zvakanakisa	Zvishoma
Kuvimbika	Yakasimba zvikuru	Inonzwa kukundikana kwe semiconductor
Kugadzirisa	Kugadzirisa michina	Kusanyanya kugadziriswa kwemakanika
Saizi	Hombe	Kapfupi

 

Maseti eMG anopa magetsi akazvimiririra uye voltage/magetsi akagadzikana kune masisitimu ekuyedza.

2. Nei MG Sets Inowanzo shandiswa pakuedza Power Transformer

 

2.1️⃣ Kugona kushanda nesimba uye kupfupisa magetsi

 

Munguva yemiedzo yakaita se:

• Bvunzo re "impedance" re "short-circuit impedance"
• Muedzo wekurasikirwa nemutoro
• Kuyedzwa kwekukwira kwekupisa

 

transformer inogona kukweva simba guru re transient current.

 

Maseti eMG anotsungirira izvi zvakanaka nekuda kwekusatenderera kwawo, nepo masisitimu emagetsi-emagetsi achigona kukanganisa kana kudzikamisa magetsi.

 

 

2.2️⃣ Simba guru (MVA level)

 

Mafekitori makuru e transformer angada:

• Kuongororwa kweMVA kwe5–20
• Dzimwe nguva 30 MVA kana kupfuura

 

MG inoisa saizi nyore nyore kusvika pakukwanisa kukuru.

Semuenzaniso, masisitimu eMG anoshandiswa kuyedza ma transformer anosvika 315 MVA / 400 kV mune mamwe mafekitori.

 

Magetsi eIGBT padanho iri anodhura zvikuru uye akaomarara.

 

 

2.3️⃣ Sinusoidal waveform yakasimba zvikuru

 

Kuyerwa kwekurasikirwa kunoda mafungu akanyatsojeka:

• Muedzo wekurasikirwa nepfungwa huru
• Muedzo wekurasikirwa nemutoro

 

Maseti eMG anogadzira mafungu emuchina we "synchronous" kubva kujenareta inopindirana.

 

Zvinhu zveIGBT zvinogadzira PWM waveform uye zvinoda mafirita, ayo anogona kuramba achiunza harmonics inokanganisa kunyatsoongorora.

 

 

2.4️⃣ Kubviswa kwemagetsi kubva pagrid

 

Maseti eMG anopa kupatsanurwa kwemuchina pakati pegridi nechinhu chekuyedza, izvo zvinobatsira:

• Deredza kusagadzikana kwegrid
• Kuvandudza kugadzikana kwekuyera
• Dzivirira grid panguva yekuyedzwa kwemagetsi ane simba guru.

 

 

2.5️⃣ Kubuda kwakawanda kwebvunzo inokurudzirwa

 

Kuedzwa kwemagetsi anokonzerwa nemagetsi e transformer kunowanzoda:

• 100 Hz
• 150 Hz
• 200 Hz

 

Maseti eMG anogadzira izvi zviri nyore nekushandura kumhanya kwejenareta kana magadzirirwo ematanda.

3. Nei Mamwe Mafekitori Ari Kutamira kuIGBT Systems

 

Pasinei nezvakanaka zveMG, masisitimu emazuva ano eIGBT / Static Frequency Converter (SFC) ari kufarirwa nekuti:

• tsoka diki
• kudzora otomatiki
• kutanga nekukurumidza
• kugadziriswa kwemakanika kushoma.

 

Vanobvumirawo ma test floors anozvishandira ega uye flexible voltage/frequency programming.

 

Saka ma laboratori matsva akawanda anosanganisa matekinoroji ese ari maviri.

4. Vatengesi Vakuru Vepasi Pose (Transformer Test Power Systems)

 

Vatengesi vepasi rose vanotungamira

• Siemens Energy - masisitimu makuru ekuyedza transformer
• OMICRON Electronics - masisitimu ekuongorora uye ekuyedza transformer
• Kambani yeDoble Engineering - mhinduro dzepamusoro dzekuongorora transformer
• Megger Group - mugadziri wemidziyo yekuedza magetsi
• HIGHVOLT Prüftechnik Dresden - yakakwirira-voltage uye bvunzo lab michina

 

Makambani aya anonyanya kupa ma laboratori akazara ekuongorora ma transformer.

5. Vatengesi Vakuru vekuChina (MG Set / Masisitimu Ekuyedza)

 

China ine vatengesi vakawanda vepasi rekuongorora matransformer emufekitori.

 

Zvishandiso zvinosanganisa

• Shanghai Trihope
• Wuhan Huatian Electric Power Automation
• Simba zvakare

Makambani aya anowanzo kupa:

• MG seti
• masisitimu ekuyedza anokurudzirwa
• masisitimu ekuyera kurasikirwa
• marabhoritari ekuyedza etransformer akakwana.
  
  
  6. Chokwadi Cheindasitiri

   

  Mumafekitori mazhinji makuru emagetsi anoshandura magetsi (>220 kV):

   

  Kurongeka kwakajairika:

  MG SET---bvunzo yemagetsi inokonzereswa

  MG SET--- bvunzo yekurasikirwa nemutoro

  IGBT/SFC --- Rubatsiro rwekugovera zvinhu zvakasiyana-siyana

   

  Saka maMG seti achiri musimboti wepasi rekuyedza rine simba guru, nepo masisitimu eIGBT achipa mukana wekuchinjika.
