在中波无线电波很强的地方使用大型起重机,起重机便成了高大的天线,起重钩常会出现高频率的异常电压,工作人员在作业时会受到强电的打击或灼伤,希望尽早的采取对策。现在作为防御措施,在起重机上安装大型谐振
Large cranes are used in places where the radio waves in the waves are very strong. The cranes have become tall antennas. The cranes often have abnormal high-frequency voltages. Workers may be hit or burned by heavy electric loads while working. They hope to adopt them as soon as possible Countermeasures. Now as a defensive measure, install large resonators on the crane
