A strong current continuous wave generator for aircraft lightning test

Abstract

The invention relates to a strong current continuous wave generating device for aircraft lightning test, comprising a DC charging device, a full-parameter lightning current A-wave generator main body, a C-wave generator main body, a control device and a measuring device. The terminal is electrically connected to the input terminal of the main body of the full-parameter lightning current A-wave generator; the high-current continuous wave generator for the aircraft lightning test, the A-wave generator uses the principle of voltage doubler energy storage circuit, and uses pulse capacitors to charge in parallel. Discharging in series to reduce the voltage level and power of the charging circuit not only successfully realizes the large load injection of the full-parameter lightning current A wave, but also greatly reduces the difficulty of the generator construction. On the basis of reducing the charging voltage of the A wave, a high voltage switch is used to isolate the A wave Wave and C wave, realize the continuous injection of A wave and C wave, and the discharge spherical gap mechanism used in the A wave generator can improve the safety of the A wave generator.

technical field [0001] The invention belongs to the field of lightning effect test equipment, in particular to a strong current continuous wave generating device for aircraft lightning test. Background technique [0002] Although high-voltage technology and pulse power technology are very mature, for the continuous generation of large-load full-parameter lightning current A-wave and C-wave, the traditional RLC parallel charging and parallel discharging method often requires high voltage, which is very important for the charging circuit and Capacitors put forward higher requirements. [0003] In the actual lightning current test, there are many such situations of continuous injection of large-load A-wave and C-wave, such as the lightning protection test of a large wingspan fuel tank. At present, there are almost no full-parameter double-exponential lightning current A-wave and rectangular C-wave for large loads in China. wave generator, and most of the discharge spherical ga...
