摘要
介绍自行设计的一种冲击实验电流信号发生器的基本原理与技术方案。该设备采用电容储能放电原理,通过程控大电流电子开关切换,产生kA级的脉冲电流,用在诸如雷电闪络传感器的测试、霍尔元件特性的动态分析和快速充磁电流源、或在电路系统实验室中作为激励信号源,用于RLC元件的动态电路特性分析一类的科研、教学实验中。因工作电压很低,具有安全、可靠和成本低廉等优点。
The article has elaborated the basic principles and technical solutions of Impact experiment about the Impact current generator.The principle of the equipment is Capacitance energy storage and discharge,KA level Pulse current is produced by the SPC high-current electronic switch.It is used for Lightning flashover Sensor test,Hall element characteristics'dynamic analysis and fast magnetization current source.It is also used for excitation source of circuit systems laboratory or such as RLC components analysis of dynamic circuit characteristics with regard to scientific research,teaching experiment.Because of the low working-Voltage,it's very safe,reliable and low-cost.
