接地螺丝因机柜本体与底座间有胶皮形成绝缘,屏蔽地汇流排与底座间绝缘,
现场控制站按规定做好接地处理。即分别接至现场控制站接地汇流排上。
I/O柜的电源地与UPS的电源地接至同一个地,保证等电位。
2.各个硬件设备操作员站、工程师站、网络交换机、服务器主机、系统显示器等采用外壳接地或直接将电源地线连接至电气接地网。
3.I/O组件模拟量模件的40端即直流24伏的负端接至逻辑地汇流排上,逻辑地汇流排接至屏蔽地,再接入总接地汇流排。
4.屏蔽地现场控制站的保护地应从机柜下方的接地螺钉接至接地分干线,现场控制站的屏蔽地应从接地汇流排接至公共连接板。
5.接地电阻测试接地系统的电阻进行测试,以保证接地能满足控制系统制造商的要求。
1用电仪表的外壳、仪表盘、柜、箱、盒和电缆槽 、保护管、支架、底座等正常不带电的金属部分,由于绝缘破坏而有可能带危险电压者,均应做保护接地。
对于供电电压不高于36V的就地仪表、开关等,当设计文件无特殊要求时,可不做保护接地。
