摘　　要：随着电子信息设备的集成度增加,电子设备越来越易遭受雷电干扰冲击,安装信号型浪涌保护器可以有效对电子设备产生保护效果。对不同结构信号浪涌保护器进行实验室脉冲测试,通过信号浪涌保护器的限压能力和分布电容对计算机串行通信的影响进行试验研究,得到浪涌保护器最大电容与信号传输波特率变化之间的关系,对不同信号传输电路中浪涌保护器的选用有实际参考价值,随着波特率的增加,浪涌保护器的最大电容逐渐减小。With the increase of the degree of integration of electronic information equipment, electronic equipment is more and more vulnerable to the impact of lightning interference, installation of signal surge protector can effectively protect the electronic equipment. The different structure signal surge protector for laboratory test pulse, through signal surge protector of limit voltage and distribution capacitance effect on computer serial communication of test research, the surge protector maximum capacitance and signal transmission baud rate change between the relationship and the selection of surge protectors in different signal transmission the baud rate, the maximum capacitance of the circuit has practical reference value, with the increase of surge protector decreases zraduallv.
