2022-07-15 16:19:54 来源:http://www.sdjkyqyb.com/ 53

中控电源在现场接地的时候有着以下注意事项,注意到这些事项能够更好的帮助备件在现场运作。
When the central control power supply is grounded on site, there are the following precautions, which can better help the spare parts operate on site.
中控电源的模拟量模件的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。
The 40 terminal of the analog module of the central control power supply, that is, the negative terminal of DC 24 V, is connected to the logic ground busbar, which is connected to the shielding ground, and then connected to the main grounding busbar.
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。
The operator station, engineer station, network switch, server host, system display, etc. are grounded by shell or directly connected to the electrical grounding grid.
中控电源接地系统的电阻必须进行测试,以保证接地能满足控制系统制造商的要求。
The resistance of the central control power supply grounding system must be tested to ensure that the grounding can meet the requirements of the control system manufacturer.
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。
The protective ground of the field control station shall be connected to the grounding branch line from the grounding screw under the cabinet, and the shielding ground of the field control station shall be connected to the public connection board from the grounding busbar.

现场控制站必须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的电源地必须接至同一个地,保证等电位。
The on-site control station must be grounded as required. That is, connect to the grounding busbar of the field control station respectively. The power ground of i/o cabinet and UPS must be connected to the same ground to ensure equipotential.
利用机组检修时间逐个复位电源系统的DPU、CPU和操作员站及数据站;删除组态中的无效I/O点,对组态进行优化。
Use the unit maintenance time to reset the DPU, CPU, operator station and data station of the power supply system one by one; Delete invalid i/o points in the configuration and optimize the configuration.
系统冗余测试: 对冗余电源、服务器、控制器、通讯网络进行冗余测试。注意系统各设备停电时,主从设备切换、网络、人机接口站是否正常;系统检修重新上电后对各设备进行切换测试。
System redundancy test: carry out redundancy test on redundant power supply, server, controller and communication network. Pay attention to whether the master-slave equipment switching, network and man-machine interface station are normal when the system equipment is powered off; After the system is repaired and powered on again, the switching test shall be carried out for each equipment.
系统灰尘清除:系统停运对所有设备进行清扫吹灰,包括主机、控制站机笼、机柜滤网、风扇等部件的灰尘清理。
System dust removal: after the system is shut down, clean and blow the dust of all equipment, including the dust removal of the host, control station cage, cabinet filter screen, fan and other components.
接地系统检修。包括端子检查、对地电阻测试;系统供电线路检修,并对UPS进行供电能力测试;注意检查DPU主机CMOS电池电量,防止CMOS数据丢失。
Maintenance of grounding system. Including terminal inspection and ground resistance test; Overhaul the power supply line of the system, and test the power supply capacity of UPS; Pay attention to check the CMOS battery power of the DPU host to prevent CMOS data loss.
检查电源系统和其他系统的接口,重要信号冗余处理,与其他系统的通信其具体情况采取单向传输和加装防火墙措施。
Check the interfaces between the power supply system and other systems, important signal redundancy processing, and communication with other systems. Take measures of one-way transmission and installation of firewall according to the specific situation.
系统上电:浙大中控电源系统大修后维护负责人确认条件具备,严格遵照上电步骤进行。
Power on of the system: after the overhaul of the central control power supply system of Zhejiang University, the person in charge of maintenance confirmed that the conditions were met and strictly followed the power on steps.
