【摘要】 [目的]目前换流站阀厅内设备维护常用人工巡检方式,为了解决该方式存在的劳动强度大、巡检不到位等问题,可在阀厅内装设红外智能监控系统。为了保证系统安装后能够对阀厅内设备全面监视,且不会对现有设备造成影响,文章在换流站现有的红外智能监测系统应用基础上,提出了红外热像仪的一种布置设计原则。[方法]通过对换流站阀厅内设备特点分析,确定红外测温系统探头型式,布置位置,并对初步布置的探头位置进行带电距离校核、遮挡校核和探测精度校核,确定最终方案。[结果]以东方换流站为例进行了应用设计和校核计算,根据校核结果调整探头位置和数量。所提原则能够实现换流站阀厅的全方位,无死角监视。[结论]算例结果对今后的类似工程具有较好的借鉴意义。更多还原

【Abstract】 [Introduction]To overcome some shortcoming such as labor-intensity and inefficient-inspection in manual inspection, which is commonly adopted in the maintenance of the equipment in a HVDC valve hall, a intelligent monitoring system could be established. For omni-direction supervising as well as no effection on the equipment, layout-principles of infrared thermal imagers are proposed in this paper, based on current application of the infrared intelligent monitoring system in convertor stations. [Method]With analysis of the characteristics of the equipment in valve hall, the type and location of the camera probes was determinated. Then, a final scheme was shaped after the check of electrical distance, block and percision. [Result]An example of the infrared intelligent monitoring system is designed and checked in Dongfang convertor station, and some adjustment in the location and number of the camera probes is made. It is illustrated that an omni-directional monitoring system could be built. [Conclusion]This work provide some guidance for similar projects.更多还原
