变电站二次回路校验系统研究与应用

Research and Application of Secondary Circuit Calibration System in Substation

提出了变电站二次回路校验系统,主要用于验证二次回路中的电压、电流互感器接线的正确性,确保各测量回路在变电站投运前,电流互感器二次回路不开路、电压互感器不短路,并避免因错接和变比选用不当而造成的设备故障,从而保障用电安全。通过现场的安装应用,验证了本校验系统不仅具有方便快捷的特点下可减轻现场检测调试人员的工作量。

Substation secondary circuit calibration system is mainly used to verify the correctness of the voltage current transformer wiring of secondary circuit,and to avoid equipment failures caused by the open current transformer secondary circuit ,voltage transformer short circuit, and the wrong wiring and improper variable selection prior to the substation operation. The field installation and application indicates that the calibration system is not only convenient and fast, but also can reduce the workload of field testing and debugging personnel.
