【摘要】 DZQZ-1地震前兆仪防雷控制器,利用了微电脑时钟控制电路,控制接触器的导通和短开,自动循环地对两组电瓶充电和放电的切换,保证了前兆设备始终处在直流电瓶供电的状态下,真正切断雷电(电源、有线宽带)窜入口,从而达到防雷的目的。更多还原

【Abstract】 In this article,the theory of lightning protection controller of earthquake precursory instrument is explained.Using microcomputer clock electric circuit to open and close contact device,the two groups of batteries can be charged and discharged automatically,witch will ensure that the earthquake precursory instrument get power from UPS online in DC status.By this process the power caused by thunder and lightning can been shuts off,so the earthquake precursory instrument will get safeguard all along.更多还原
