backup protection

基本解釋

A new scheme for transformer backup protection based on longitudinal comparison principle is proposed.
提出了一種基于縱聯(lián)比較原理的變壓器后備保護(hù)新方案。
The traditional protection has some shortcomings: long operation time of backup protection, not distinguishing overload from fault of line and so on.
傳統(tǒng)保護(hù)存在后備保護(hù)動(dòng)作時(shí)間過(guò)長(zhǎng)和不能區(qū)分線路過(guò)載與故障等不足。
For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.
對(duì)于后備保護(hù)裝置防止高阻抗接地故障，將配置一只雙極方向過(guò)電流繼電器，同瞬時(shí)跳閘附件的時(shí)間成反比。

后備保護(hù)
It deflates the influencing area of faults and reduces operation time delay of backup protection.
該方案有效解決了變壓器高壓側(cè)后備保護(hù)對(duì)中、低壓側(cè)故障靈敏度不足的問(wèn)題,縮小故障影響范圍,縮短后備保護(hù)動(dòng)作延時(shí)。
