浅谈ADF改装施工中的接地技术

Discussion about the Grounding Technology in ADF Modification Construction

文章研究的接地技术在飞机加改装电子设备时非常重要,但常常被施工人员忽视。据不完全统计,每年约有20%~30%的飞机电子故障与电气设计或施工中的接地不良有关,这不仅会引起设备工作异常,甚至还会损坏设备^([1])。另外飞机飞行中遇到高强度电磁辐射或闪电时,有效的屏蔽线接地能防止其造成的电磁干扰。

Grounding technology is very important in the modification of electronic equipment of aircraft, but it isusually easy to be overlooked by workers. According to incomplete statistics, there are about 20% to 30% aircraftelectronic faults caused by bad grounding in electrical design or construction every year, and those faults may result inthe equipment working properly or even the equipment damage^（[1]）; besides, the aircraft in flight, sometimes encountershigh intensity electromagnetic radiation or lightning shield line, under this circumstance, grounding can prevent electromagnetic interference effectively.
