配电变压器非电量保护技术分析

Technical Analysis of Non-Electric Quantity Protection of Distribution Transformer

介绍了常见的三种配变非电量保护:温度保护(油面温控、绕组温控、电子温控),压力保护(压力释放阀),瓦斯保护(气体继电器)等,给出了其相应的施工细节。最后提出了配变非电量保护与微机保护装置的配合应注意的问题。

This article introduced three common non-electric quantity protection of distribution transformer, tempera- ture protection （ oil surface temperature control, winding temperature control, electronic temperature control ） ; pressure protection （ pressure release valve ） ; gas protection （ gas relay ） , etc. It gave the corresponding construction details. Fi- nally proposed the problems that should be paid attention when non-electric quantity protection of distribution transformer matching with microcomputer protection device.
