| Abstract: | Operating condition of surge arrester was analyzed and calculated according to operating principle of passive high voltage direct current(HVDC) transfer switch.Key technologies of surge arrester such as protection level and energy release ability were researched in depth.The basis of current impulse waveform(front time of impulse is not less than 250μs) of residual voltage measurement of surge arrester for HVDC transfer switch and the selected value of ultimate energy release ability of ZnO varistors were suggested.These conclusions play an instructive role in the design of surge arrester for HVDC transfer switch in the actual construction. |
| Keywords: | direct current(DC) transfer switches surge arresters impulse response effect ZnO varistors ultimate energy release ability |
