摘　　要：桌面毛细管快放电X射线激光实验装置,是研究高压大电流放电直接激励X射线激光放大技术的快脉冲发生器。其特点是电压高、电流大、脉冲陡、干扰强、空间小。常规绝缘结构的高压无感电阻测量系统难以满足其高电压脉冲测量的要求。研究了一种新型绝缘结构高压无感电阻电压测量传感器及两级分压测量系统,介绍了传感器的绝缘结构原理、测量系统的组成以及高电压测量结果,并从理论上验证和分析了测量系统的测量结果及相对误差。实验结果表明,新型绝缘结构高压无感电阻能同时具有较高电位梯度和较小电感的优点,设计的电压测量系统峰值误差小,抗干扰能力强,可以较好地满足毛细管快放电X射线激光实验装置中的高电压测量。Table-top capillary fast discharge X-ray experiment facility is used to study the X-ray laser amplification by directly fast electric pulse excitation of gases. Due to the characteristics of high voltage, large current, fast pulse, strong disturb and small space available, it is difficult to carry out the high voltage pulse measurement in this setup by a general high voltage non-inductance resistor and single grade voltage-division measuring system. A voltage sensor composed of a kind of high-voltage new insulation structure non-inductance resistor by making slots on the surface of an insulating rod and a two-grade voltage-divider measuring system were developed to accomplish the measurement of the high voltage pulse. The principle of insulation structure of the voltage sensor, the measurement system and the experiment results have been introduced, and the error of the measurement system has also been discussed in detail. Application results indicated that the new voltage-sensor has an advantage of higher potential gradient and smaller inductance simultaneously in air dielectric, and the measurement system has a good anti-disturb ability and smaller firstly-peak measuring error.
