The Earth System of an ATC System and Fire Prevention Measures for Computer Rooms

在计算机系统的接地系统中,一些问题至今尚无定论,本文结合几个计算机系统安装调试的经验,及现有的ATC雷达模拟系统实体,就机房屏蔽地线、防雷击地线、交流地线、系统地线给予介绍和简单的论述,并给出一些经验值,还说明了直流地悬空的危害和地桩的埋设方法。另外,简要介绍了机房的防火设施,以便有关单位参考。

Certainty has up to now been lacking about some problems con- cerning the earth system of a computer system.Basing themselves on prac- tical experience in installing and debugging ATC systems and the ATC ra- dar simulator in the Training Centre,the authors of this article give some brief explanation and discussion of the masked earth of a computer room, the earth of a lightning arrester,the alternating earth and the system earth.Some empiric data,the danger of a floating direct earth and a me- thod of driving in the earth stake are also presented.Finally,fire preven- tion measures for computer rooms are introduced in brief.
