变电站主变电压遥测量接入方式的探讨

摘要

分析了某变电站一起主变遥测数据中断故障的原因，通过对故障处理过程以及设备运行现状的分析，指出与保护共用电压切换装置的主变电压测量存在一定风险，提出了相应的对策。在变电站二次回路六统一设计模式中，应进一步明确主变电压遥测量接入方式，消除可能的安全隐患。%This paper analyzes reasons of a remote data measurement interruption failure of main transformer in a substation. By analyzing the failure solution process and the operation status of the equipment, this paper indicates that it is risky to measure main transformer voltage that protects common voltage switching device. The paper also proposes some countermeasures. In the "Six Unification" design of the substation secondary loop, connection mode for remote measurement of main transformer voltage should be clarified further to e-liminate potential safety risk.
