中控室的防雷计算与设计

Calculation and Design of Lightning Protection in Central Control Room

雷电通常通过交流电源线、信号线、地电位反击等方式入侵电子信息系统,从而对设备造成破坏。根据国家相关防雷接地标准要求,对某选矿厂中控室进行防雷计算,得出电子信息系统雷电防护等级定为B级的结论,并针对该中控室进行了防雷设计,最终选用XHB-PB1/2C-80浪涌保护器,确保了中控室的仪器设备安全。

Lightning usually intrudes one lectronic information systems by means of alternating current power line,signal line and positional counter attack and thus causes damages to the equipment.According to the requirements of relevant national lightning grounding standards,the author calculated lightning protection of the central control room in aconcentrator and concluded that the lightning protection level of the electronic information system shall be set as class B.Therefore,the author made lightning protection design of the central control room and finally selected XHB-PB1/2c-80 surge protectors to secure safety of instrument equipment in the central control room.
