發布日期:2022-04-25 點擊率:26

有關頻閉鎖距離保護的基本特點,頻閉鎖距離保護的四個特點,高頻閉鎖距離保護是以線路上裝有方向性的距離保護裝置作為基本保護,增加相應的發信與收信設備,通過通道構成縱聯距離保護。

頻閉鎖距離保護的特點

高頻閉鎖距離保護是以線路上裝有方向性的距離保護裝置作為基本保護,增加相應的發信與收信設備,通過通道構成縱聯距離保護。

頻閉鎖距離保護的特點

1、能足夠靈敏和快速地反應各種對稱與不對稱故障;

2、仍保持后備保護的功能;

3、電壓二次回路斷線時保護將會誤動,需采取斷線閉鎖措施,使保護退出運行。

4、不是獨立的保護裝置,當距離保護停用或出現故障、異常需停用時,該保護要退出運行。
