【摘要】 文章主要介绍屏蔽室的接地问题,通过大量实验得出以下结论:①单点接地的屏蔽效能优于多点接地。②接地电阻大小对屏蔽室屏蔽效能没有影响。③接地线的长短对屏蔽效能影响不明显,而对信号泄漏有影响。④屏蔽接地线比裸露接地线信号泄漏小。更多还原

【Abstract】 Four test results of shielded enclosure is present, conclusion are given about the shielding enclosure grounding after these test:①the shielding effectiveness of the shielding enclosure with one grounding position better than that of several grounding positions.②the grounding resistance not affect the shielding effectiveness of the shielding enclosure. ③ the length of grounding line affectthe shielding effectiveness of the shielding enclosure weakly, but it affect the signal leakage. ④the signal leakage through the shieldingcable is less than the bare cable.更多还原
