摘要
随脉冲功率技术向高重复频率、长寿命等方向发展,储能元件和开关元件在瞬态强场条件下的稳定性能检测十分必要。基于固态开关技术研制了一种百kV,μs时间尺度下的瞬态强场测试平台,主要由高压直流充电电源、初级单元、脉冲变压器、磁脉冲压缩网络、复位系统和测试腔体组成,实现了一体化结构,使用便利。首先,针对电容器测试条件,建立了完整的电路模型,详细设计了系统中各关键参量;然后,利用晶闸管组件作为初级单元控制开关,利用磁开关进行两级脉冲压缩,建立了实验装置;最后,给出了40 nF小批量陶瓷电容器的典型实验测试结果,测试电压50 kV,脉冲宽度1μs,重复频率10 Hz,运行时间85 min(对应51000个脉冲),平台稳定可靠性良好,为后续开展相关测试研究奠定了基础。
With the development of pulse power technology to high repetition rate and long life,it is necessary to test the stability of energy storage and switching components under transient intense field.This paper presents a solid-state platform for transient intense field test at several tens kilovolts with charging and discharging time in microsecond region.The platform consists of a high voltage power supply,a primary unit,a core-type pulse transformer,a magnetic compression network,core reset power supplies and a test cavity,hence it has an integrated structure and is easy to use.A circuit model is presented to optimize the electrical parameters of the platform.Then,the test platform is built up and experimented.A group of serial connected thyristors are used as control switch in the primary unit for pulse charging and high power magnetic switch is used for discharging in the test cavity.Preliminary results are obtained with ceramic capacitors of 40 nF under test,of which the test voltage is 50 kV,the pulse width is 1μs with repetitive rate of 10 Hz and operation time of 85 min(51000 pulses),indicating the platform is stable and reliable.The research results could setup good foundation for further investigation into related test.
