韓國AUTOMA,AS80,AS100,制造廠家　　注意事項：a．試驗時應先去磁（可加交流電壓平緩升降幾次），然后將電壓逐漸升至勵磁特性曲線的飽和點即可停止；b．如果該繞組勵磁特性的飽和電壓高于2kV，則現場試驗時所施加的電壓一般應在2kV截止，避免二次繞組絕緣?。　　可是這樣合計為鐵素基體，脆性很大，高溫強度低，限制了其應用。為了合金在1200-1300℃的抗氧化性能，出一些高溫下能形成Al2O3的高溫合金，國外典型合金有HaynesAlloy214、эп747、Inconel602、Inconel603等。重慶儀表材料在國外合金基礎上，通過Cr、Al含量，并采用晶界精華和強化技術，研制出一種新型抗氧化高溫耐熱合金3YC52，其主要原因是在高溫下除形成Al2O3、Cr2O3的混合氧化膜外，還能形成致密、單一α-Al2O3保護膜。
