设计了一种开关型电阻分压器,用于对金属丝电爆炸的实验研究。在电容器充电过程中,开关断开,保证分压器的高低压臂电阻不因电压高而烧毁;在金属丝落入高压电场中的时候,开关闭合,在电阻分压器上输出电压。合理的设计开关结构、电阻参数和精确的控制开关的通断时间,可以准确的测量金属丝电爆炸过程中的电压波形。此分压器使用方便,所测波形稳定可靠,为后续的实验奠定了基础。
The switching resistance divider is designed for experiment research of wire electrical explosion. In the process and after the completion of building the high voltage electric field, the switch is off to guarantee the resistor of the divider will not be burned due to high voltage. When the wire falls into high voltage filed, the switch is on, and the voltage signal is measured from the resistance divider. With proper design of switch structure and precise control of on-off switch time, the voltage waveform can be measured accurately in wire electrical explosion process. The resistance divider is convenient to use and the measured waveform is stable, which lays the foundation for the following Keywords:
