摘 要:设计了一种用于叠层间隙型防雷保护器的功能指示电路。该电路利用间隙击穿电压和指示电路动作电压比较原理,结合熔丝、发光管等器件,通过电子方式和机械方式完成对防雷器功能的指示。基于相关标准,测试了与防雷器的浪涌冲击配合效果,试验验证表明,该指示电路可以有效地指示多层(叠层)间隙型防雷器的功能状态,使终端客户方便、清晰地确认防雷器的性能状况。This paper designed a kind of function indication circuit used for gap-stack type of lightning protection device. This circuit usedthe principle of comparing the gap breakdown voltage with the indication circuit operation voltage. Combined with the fuses and the luminoustube devices, this system indicated the functions of lightning protection device via the electronic mode and the mechanical mode. Onthe basis of the relevant standard, the results of surge impact coordinated with the lightning protection device were tested. The experimentalverification shows that this indication circuit can effectively indicates the functional status of gap-stack lightning protection device to makethe terminal client conveniently and clearly affirm the performance conditions of the lightning protection device.
