Abstract

The invention discloses a test device for direct effect of vehicle-mounted lightning, which comprises measuring and controlling units, coupling units, an output terminal and a plurality of generator units. The generator units are connected to the coupling unit through a coaxial high-voltage cable, and the coupling unit and the output terminal are connected. The measuring and controlling unit is respectively connected to the generator unit and the coupling unit through the industrial field bus. The generator unit has a partitioned container square cabin structure, including a generator cabin, aDC power supply box and a generator body compartment. The generator cabin is provided with a generator which can be used for field generation. The coupling unit has a non-blocking square cabin structure, and the measuring and controlling unit has a shielded cabin structure. The test device for direct effect of vehicle-mounted lightning can be directly transported by the vehicle through lifting tothe test site for testing, or can be fixed in the laboratory for testing, and has lower loop inductance.

Description

technical field [0001] The invention relates to the technical field of lightning direct effects, in particular to a test device for vehicle-mounted lightning direct effects. Background technique [0002] The direct effect of lightning on aircraft includes not only the magnetic field force and Joule heating effect caused by large current, but also the impact force effect of lightning high-voltage shock wave. The American Society of Mechanical Engineers SAE, the American military standard MILSTD and the European Civil Aviation Organization EUROCAE have made detailed regulations on the test waveform and test method of the direct effect of lightning on the aircraft and its components. Different areas of aircraft such as large aircraft are tested by the combination of current A component, B component, C component and D component using the direct effect of lightning. However, the existing test devices are generally fixed in the laboratory and cannot be tested outdoors. The loop i...
