Saitin MG yana samar da wutar lantarki mai zaman kanta da kuma ƙarfin lantarki/hawa mai ƙarfi don tsarin gwaji.
- Dalilin da yasa ake fifita saitin MG don gwajin na'urar canza wutar lantarki
2.1️⃣ Ƙarfin ikon yin amfani da gajerun hanyoyi da kuma ɗaukar kaya fiye da kima
A lokacin gwaje-gwaje kamar:
- Gwajin juriya na gajere
- Gwajin asarar kaya
- Gwajin hauhawar zafin jiki
na'urar canza wutar lantarki (transformer) na iya jawo babban wutar lantarki mai wucewa.
Saitin MG yana jure wannan sosai saboda yadda suke juyawa, yayin da tsarin lantarki na wutar lantarki na iya yin tuntuɓe ko iyakance wutar lantarki.
2.2️⃣ Ƙarfin wutar lantarki mai yawa (matakin MVA)
Manyan masana'antun na'urorin canza wutar lantarki na iya buƙatar:
- Samar da gwajin MVA 5–20
- Wani lokaci 30 MVA ko fiye
MG yana saita sikelin cikin sauƙi zuwa babban ƙarfin aiki.
Misali, ana amfani da tsarin MG don gwada har zuwa 315 MVA / 400 kV na transfoma a wasu masana'antu.
Kayayyakin wutar lantarki na IGBT a wannan matakin suna zama masu tsada da rikitarwa.
2.3️⃣ Tsarin raƙuman sinusoidal mai ƙarfi sosai
Ma'aunin asara yana buƙatar daidaiton raƙuman ruwa:
- Gwajin asarar asali
- Gwajin asarar kaya
Saitin MG yana samar da raƙuman sine na halitta daga janareta mai daidaitawa.
Kayayyakin IGBT suna samar da yanayin PWM kuma suna buƙatar matattara, wanda har yanzu yana iya gabatar da jituwa waɗanda ke shafar daidaiton ma'auni.
2.4️⃣ Warewa daga wutar lantarki daga grid
Saitin MG yana ba da keɓancewa ta injiniya tsakanin grid da abin gwaji, wanda ke taimakawa:
- Rage rikice-rikicen grid
- Inganta daidaiton ma'auni
- Kare grid ɗin yayin gwaje-gwajen ƙarfi mai ƙarfi.
2.5️⃣ Fitowar mita mai yawa don gwajin da aka haifar
Gwajin ƙarfin lantarki da aka haifar da mai canza wutar lantarki sau da yawa yana buƙatar:
- 100 Hz
- 150 Hz
- 200 Hz
Saitin MG yana samar da waɗannan cikin sauƙi ta hanyar canza saurin janareta ko tsarin sandar.
- Dalilin da yasa wasu masana'antu ke ƙaura zuwa Tsarin IGBT
Duk da fa'idodin MG, tsarin IGBT / Static Frequency Converter (SFC) na zamani yana samun karbuwa saboda:
- ƙaramin sawun ƙafa
- sarrafa atomatik
- farawa cikin sauri
- ƙarancin gyaran injina.
Suna kuma ba da damar yin gwaji ta atomatik da kuma shirye-shiryen ƙarfin lantarki/mita mai sassauƙa.
Dakunan gwaje-gwaje da yawa na zamani sun haɗa fasahohin biyu.
- Manyan Masu Kaya na Duniya (Tsarin Gwajin Wutar Lantarki na Transformer)
Manyan masu samar da kayayyaki na duniya
- Siemens Energy - manyan tsarin gwajin transformer
- OMICRON Electronics - tsarin bincike da gwaji na transformer
- Kamfanin Injiniyan Doble - mafita na gwajin canjin wutar lantarki mai ci gaba
- Megger Group - mai ƙera kayan aikin gwajin wutar lantarki
- HIGHVOLT Prüftechnik Dresden - babban ƙarfin lantarki da kayan gwajin gwaji
Waɗannan kamfanoni galibi suna samar da cikakkun dakunan gwaje-gwaje na gwajin na'urorin canza wutar lantarki.
- Manyan Masu Kaya na Kasar Sin (Saitin MG / Tsarin Gwaji)
Kasar Sin tana da masu samar da kayayyaki da yawa don gwajin benaye na masana'antar transfoma.
Masu haɗa kayan aiki
- Shanghai Trihope
- Kamfanin sarrafa wutar lantarki na Wuhan Huatian
- Sake kunna wuta
Waɗannan kamfanoni yawanci suna ba da:
- Saitin MG
- Tsarin gwaji da aka haifar
- tsarin auna asara
- cikakken dakunan gwaje-gwajen gwajin transformer.
- Gaskiyar Masana'antu
A mafi yawan manyan masana'antun samar da wutar lantarki (>220 kV):
Tsarin yau da kullun:
Gwajin ƙarfin lantarki da aka haifar da MG SET
MG SET--- gwajin asarar kaya
IGBT/SFC --- Kayan aiki mai canzawa na taimako
Don haka saitin MG har yanzu shine ginshiƙin benaye masu ƙarfin lantarki, yayin da tsarin IGBT ke ba da sassauci
