Problems solved by technology

If the current conventional test method is used to carry out the lightning indirect effect test on special vehicles, it is impossible to effectively assess the indirect effect caused by lightning hitting the lightning rod, which is placed on the ground, and the indirect effect on the nearby vehicles, and it cannot reflect the indirect effect caused by the ground. The effect of conduction on the formation and effect of vehicle indirect effects
When taking special vehicles for field work as the test object, the current test method is not pertinent

Embodiment Construction

[0042] The basic idea of ​​the present invention: a test method for the indirect effect of lightning on special vehicles is proposed. Combined with the actual situation of lightning discharge in nature, the discharge process of lightning hitting the lightning rod is simulated by high current and high voltage, and the special vehicle and its internal electronic equipment are tested. The lightning protection situation is tested and assessed, the test configuration, process, method and waveform parameters are clarified, and a unified and executable method is formed to solve the current problem of lack of standard method reference, which can provide technical support for the lightning indirect effect protection capability of special vehicles.

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] When the vehicle is working in the field, the lightning rod is used for lightning protect...

Abstract

The invention provides a test method for lightning indirect effects of a finished special vehicle. The practical discharging condition of lightning in the nature is combined, a heavy current and a high voltage are used to simulate the discharging process of a lightning rod struck by lightning, lightning protection condition of the special vehicle and electronic equipment therein is tested, test configuration, flows, methods and waveform parameters are made clear, and a unified executable method is thus formed. The problem that a standard method for reference lacks in the prior art is solved, and technical support is provided for ensuring the capability of protecting the finished special vehicle against the lightning indirect effects.

Description

technical field [0001] The invention relates to a method for testing the lightning indirect effect of a special vehicle, that is, a method for judging the protection ability of a special vehicle against the lightning indirect effect, which belongs to the lightning indirect effect test of the special vehicle, and tests the protection of the special vehicle for the lightning indirect effect technical areas of competence. Background technique [0002] Special vehicles usually work in a field environment, where the climate or geographical environment is relatively complex, especially when they are in an open field, the probability of being subjected to lightning is relatively high, and corresponding protective measures need to be taken. [0003] The harm of lightning to special vehicles can be divided into direct effect and indirect effect. The direct effect of lightning means that lightning directly hits a special vehicle, which can cause the vehicle to be broken down, melted,...
