Bulk current injection equivalent test method for coupling channel of unshielded multi-core wire

从非屏蔽多芯线缆单一线对大电流注入等效替代辐照模型出发,提出了单一线对的大电流注入严格等效辐照的试验方法.以非屏蔽四芯线为试验对象,探索了非屏蔽多芯线缆终端响应规律,发现各线对并不能同时严格等效.在此基础上,提出了非屏蔽线缆耦合通道加严等效的试验方法,并进行了试验验证.试验结果证明,提出的大电流加严等效注入的方法是可以替代强场辐照试验的,解决了武器装备系统通过性试验的问题.

Starting from the equivalent replacing radiation model of a single pair of unshielded multi-core wires with a single pair of large current injection, a test method for strict equivalent radiation of a single pair of large current injection is proposed. Taking the unshielded four-core wire as the test object, the terminal response law of the unshielded multi-core wire is explored, and it is found that each pair of wires can not be strictly equivalent at the same time. The equivalent test method of tightening the coupling channel of unshielded wire is proposed and verified by the test. The test results prove that the proposed method of equivalent injection of bulk current tightening can replace the strong field irradiation test, which solves the problem of the passing ability test of the weapon equipment system.
