Abstract

A lightening induction damped oscillation wave generator for onboard equipment comprises a continuous adjustable voltage source, a potentiometer, a change-over switch and a relay; the continuous adjustable voltage source is a 10kV continuous adjustable voltage source; the potentiometer W adjusts the on/off time of an internal circuit to change the size of direct current output voltage for adjusting the output voltage of the voltage source; the change-over switch is a five-port change-over switch; the circuit is enabled to work at one state every time due to the switching of the change-over switch K and five outputs are realized. The circuit is simple in structural design and stable in work performance, all output circuits are not mutually interfered with, the output signal has high precision, the operation is convenient, the measurement precision is high, the voltage withstanding level is high and the work is safe and reliable; the lightening induction damped oscillation wave generator for the onboard equipment is widely used for the test on the lightning transient voltage endurance capacity.

Description

technical field [0001] The invention relates to a lightning induction damping oscillatory wave generator for airborne equipment, which is used for testing the simulated lightning acting on the airborne equipment. Background technique [0002] As a kind of natural disaster, lightning disaster poses a threat to human life and property. It ranks No. 9 of the 10 natural disasters in the international disaster prevention and mitigation plan formulated by the United Nations, and its hazards are widespread all over the world. The weather accompanied by thunder and lightning is called thunderstorm in meteorology. In thunderstorm weather, when the potential difference between the clouds or between the cloud and the ground reaches a certain level, a discharge phenomenon will occur. The lightning strikes the ground or hits the ground. People and objects cause harm, and lightning strike accidents have occurred, ranging from property damage to casualties. As for airborne equipment also ...
