產(chǎn)品特點(diǎn):
在隔離變壓器建立新的中線-接地就可解除電網(wǎng)中共模干擾和其它中線的困擾,隔離變壓器將三線△接線轉(zhuǎn)換為四線Yo系統(tǒng),加屏蔽就進(jìn)一步免除了由變壓器內(nèi)部耦合的高頻脈沖干擾和噪音,雖然有屏蔽的隔離變壓器對(duì)各種N-G來(lái)的干擾(脈沖和高頻噪聲)能有效防止,但變壓器必須正確妥善接地,十分嚴(yán)格,否則抗共模干擾將無(wú)效果。
特性優(yōu)點(diǎn):
1 高度隔離
2 N-G性能良好
3 高度共模干擾抑制
4 將△轉(zhuǎn)換為Y
5 電壓抽頭容易轉(zhuǎn)換
6 按用戶的特殊性能要求設(shè)計(jì)
