变压器挡位远方监测探讨及技术改造

成都电业局新建的变电站均采用了变电站无人值班的监控方式。为保证有载调压变压器挡位监控方式的顺利实施,对变电站挡位远方监测数据的正确性提出了较高的要求。现在新建的变电站对变压器有载分接开关要求能实现遥调,其位置遥信,采用了直接接线采集和挡位变送器方式,能较好地实现主变压器挡位的非电量-电量转换监测问题。

Discussion on Remote Monitoring of Transformer Tap Position and Its Technical Reconstruction

The newly-built substations all adopt non-attended style in Chengdu Electric Power Bureau.In order to ensure the successful implementation of tap position monitoring of load-ratio voltage transformer,the higher requirements are put forward for the correctness of remote monitoring data of transformer tap position.Now newly-built substations are all required remote control of on-load tapping switch of transformer and remote signaling of its position.It adopts direct grounding acquisition and the tap position transducer,which can realize the monitoring of conversion between electrical quantity and non-electrical quantity of transformer tap position.
