一种基于变电站感应磁场和感应电压的测量装置

A Measuring Device Based on Induced Magnetic Field and Induced Voltage in Substation

在实际变电检修中,高压试验大多在现场进行。在500 kV或换流站中,一部分线路带电,另一部分不带电。对停电的线路进行高压预算,旁边带电的线路会产生强磁场影响试验仪器,从而影响试验结果。为避免在强磁场环境中进行高压试验造成试验结果误差,提出一种测量磁场和感应电压的测量装置。当所处的环境是强磁场及设备上感应电压很大时,能够建议检修试验人员换个位置或环境进行测量。

In the actual substation maintenance,the high voltage test is mostly carried out on site. In 500 kV or converter station,one part of the line is live and the other part is not. The high-voltage budget is made for the power-off line,and the power line nearby will produce strong magnetic field to affect the test instrument,thus affecting the test results. In order to avoid the test result error caused by high voltage test in strong magnetic field environment,a measuring device for measuring magnetic field and induced voltage is proposed. When the environment is a strong magnetic field and the induced voltage on the equipment is very large,it can be recommended that the maintenance and test personnel change the location or environment for measurement.
