Abstract

In order to evaluate the attenuation characteristics of low frequency pulse magnetic field penetrating through reinforcement nets, different types of reinforcement cages are made. Radiation effect experiments under low frequency pulse magnetic field are done. Effect rules on attenuation characteristics of different diameter, different mesh size, different intersection point treatment, different connection mode and different radiation parameters are carried out. The results show that different types of reinforcement net have a kind of shielding effectiveness against low frequency pulse magnetic field. However, the shielding effectiveness is low. Under the experiment condition, the shielding effectiveness is below 7dB of signal reinforcement net. Larger the diameter, smaller the mesh size, full welding and colligation, higher the shielding effectiveness will be. The reinforcement nets with dissimilar forms can be comprehensively utilized in protecting constructions for the best result.
