摘　　要：基于反铁电脉冲电容器的特点,目前暂没有相应的国家标准对脉冲电容器的容量、放电电流测试条件进行详细规定,为了形成反铁电脉冲电容器的测试方法和要求,借助以触发管为核心的放电回路,来研究反铁电脉冲电容器与常规高压电容器的差异。通过比较反铁电脉冲电容器与常规高压电容器耐压后容量变化,可知反铁电脉冲电容器的容量在耐压后上升幅度超出常规高压电容器要求的允许偏差范围,常规测试方法不能满足反铁电脉冲电容器的容量测试要求,通过在不同电压下比较反铁电脉冲电容器充放电次数,可知放电电流测试的电压值高于额定工作电压,电容器的可靠性会下降,以此来确认可靠性高的电压使用范围。而上述试验结果,为形成适合反铁电脉冲电容器的测试方法和要求提供了借鉴。Based on the characteristics of antiferroelectric pulse capacitor, there is no relevant national standard for the test conditions of capacitance and discharge current of antiferroelectric pulse capacitor. In order to form the test methods and requirements of antiferroelectric pulse capacitor, the difference between antiferroelectric pulse capacitor and conventional high voltage capacitor was studied by using the discharge circuit with trigger tube as the core. By comparing the capacitance change of antiferroelectric pulse capacitor with that of conventional high voltage capacitor after withstanding voltage, it can be seen that the rising range of the capacitance of antiferroelectric pulse capacitor after withstanding voltage exceeds the allowable deviation range required by conventional high voltage capacitor. The conventional test method can not meet the capacitance test requirements of anti-ferroelectric pulse capacitor. By comparing the charge and discharge times of antiferroelectric pulse capacitor under different voltage, it can be concluded that the voltage value measured by discharge current is higher than the rated working voltage, and the reliability of capacitors decreases, so as to confirm the high reliability voltage range. The above test results provide a reference for the formation of suitable test methods and requirements for antiferroelectric pulse capacitors.
