整流變壓器
這種變壓器專門用于可控硅變流器或者二極管整流器系統(tǒng)。
此類轉(zhuǎn)換設(shè)備對(duì)變壓器的影響和附加的結(jié)構(gòu)要求如下:
• 諧波電流造成的負(fù)載增加
• 多繞組系統(tǒng)內(nèi)相電流的平衡(如 12 脈沖系統(tǒng))
• 短時(shí)過載系數(shù)達(dá)到 2.5
Rectifier transformer
This kind of transformer is designed for the special demands of thyristor converter or
diode rectifier system.
The effects of such equipment on transformers and additional structure requirements are
as follows:
• Increased load by harmonic currents
• Balancing of phase currents in multiple winding system (e.g. 12-pulse system)
• Short-time overload factor up to 2.5
