摘　　要：由于现行标准未对金属回线转移开关辅助回路(MRTB)参数测试作出规定,为掌握压换流站内MRTB进行了现场实测,电容测量值为60.68μF,计算电感为17.37μH、阻尼电阻R为0.037Ω,结果满足辅助回路振荡特性要求。Since the current standard does not stipulate the parameter test of the auxiliary loop of metal loop transfer switch(MRTB),in order to master the equipment state of MRTB,the principle analysis is carried out,and the test scheme is formulated according to the equipment condition after on-site installation.Make field measurement to MRTB in some UHV converter station,the capacitance measurement value is60.68μF,the calculating inductance is17.37μH,the damping resistance is0.037Ω,whose results meet the requirements of the oscillation characteristics of auxiliary loop.
