摘　　要：根据1 MV,30 ns上升沿脉冲源的同轴油介质传输线的结构特点,在传输线的末端设计了环形电容分压器作为脉冲源的高电压测量探头,利用不锈钢薄膜连接传输线外筒与负载外筒,构成回流测量负载的电流. 电容分压器的分压比和不锈钢薄膜的灵敏度采取直接标定的方法测定。实验结果表明,该探头性能稳定、时间响应快、功率负荷大,是测量脉冲电流与电压的一种理想工具。According to the coaxial cylindrical structure of oilline on 1 MV, 30 ns pulsed power source, an annular capacitive voltage divider was designed in the end of the oilline as pulsed voltage monitor. A stainless steel film connecting the outer tube and load was designed as pulsed current monitor. The capacitive voltage divider’s probe and the stainless steel film monitor’s probe were calibrated on line. The results show that the capacitive voltage divider and the current monitor are ideal probes for measuring high pulsed voltage and current.
