The present invention relates to a grounding resistance measuring method for a lightning protection device. The method comprises the following steps of measuring the grounding resistance value of thelightning protection device by adopting a resistance measurement instrument; converting the grounding resistance value into an analog signal by the resistance measurement instrument; transmitting theanalog signal to a receiving instrument by a wireless transmission system; converting the analog signal into a digital signal by the receiving instrument; processing the data of the grounding resistance value of the lightning protection device and storing the processed data by the receiving instrument. By adopting the grounding resistance measuring method for the lightning protection device, the grounding resistance can be quickly detected before the occurrence of thunderstorms in summer, so that problems can be timely found and corrected. Therefore, the device can be prevented from being struck by lightning. The labor intensity of the detection personnel is reduced, and no long test line is required. Meanwhile, the detection personnel do not need to personally get to the dangerous zone ofthe lightning protection device, so that the risk of measurement is reduced. The interference and the influence during the measurement of an external electromagnetic field are reduced. The requirement of practical application can be well met.
Description
technical field [0001] The invention relates to a method for measuring grounding resistance of a lightning protection device. Background technique [0002] Good grounding is one of the most effective means to shunt and discharge direct lightning and lightning electromagnetic interference energy, and it is also the basis of the potential equalization compensation system. The lightning current discharges to the earth through the lightning protection belt, down conductor, and grounding body, thereby protecting the safety of buildings, personnel and equipment. Therefore, it is very important to check whether the grounding resistance of the lightning protection device is qualified. [0003] The method for detecting the grounding resistance resistance value of the lightning protection device in the prior art has the following disadvantages: the detection personnel need to wire and connect measuring instruments, etc., and the whole process is complicated and laborious; the detectio...
