Abstract

The invention discloses a system for testing performance of a field sensitive type electromagnetic pulse protection material. The system comprises a high-frequency noise simulator, a testing device, an attenuator and an oscilloscope, wherein the signal output end of the high-frequency noise simulator is connected with the signal input port of the testing device through a coaxial cable; the signal output port of the testing device is connected with the attenuator; the signal output end of the attenuator is connected with the signal end of the oscilloscope; the high-frequency noise simulator is taken as a signal source; the signal output port of the testing device is connected with the attenuator; attenuated signals are displayed through the oscilloscope; the high-frequency noise simulator is taken as a signal source for providing square signal input for the system; as the voltage of output square waves is higher than kilovolt, but the oscilloscope can only endure voltage of tens of volt, the attenuator with corresponding parameters needs to be connected between the testing device and the oscilloscope; finally, the output waveforms are displayed at the oscilloscope, and the response time and the resistance of a tested material can be confirmed by observing the waveforms displayed by the oscilloscope.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility experiments, in particular to a performance testing system for field-sensitive electromagnetic pulse protection materials. Background technique [0002] The ideal field-sensitive environment-adaptive electromagnetic protection material is an insulating material in the case of low field strength, and has no shielding effect on electromagnetic waves. When it is disturbed or attacked by an external strong electromagnetic pulse, the external electromagnetic field suddenly increases significantly and exceeds a certain critical value. When the field is strong, due to the unique electrochemical and energy structure characteristics of the material, it can sense the changes in the external electromagnetic environment and quickly adjust its electromagnetic properties. Boost 10 2 ~10 5 The order of magnitude makes the material that is usually an insulator quickly become a highly condu...
