长期高损台区会给供电企业带来巨大的经济损失，而传统的人工现场摸排费时费力且计量系统监测功能不足。该产品综合采用了先进的HPLC通信技术、ARM硬件处理器、专业级实时LINUX嵌入式自主软件设计、高精度电能计量和同期数据对比等技术设计，能根据从机和主机获取的数据，多台设备同时在同一相线上前后使用，对线损异常进行分析排查，进一步研究高线损发生的位置和可能的原因。装置应用于低压配网时，通过对台区线路负荷监测，实现从变压器–分支箱–表箱分级、分相线损分析预警功能，具备HPLC自组网通讯、电能计量、防窃电监测、同期线损比对等功能，从而保证挖掘高线损的位置。能够现场对高损区域精准智能判断，从而迈向高质量、高效率、数字化的崭新线损异常排查工作模式。实现台区精益化线损管理，达到电网降损增效的效果。
Long-term high-loss areas can bring huge economic losses to power supply enterprises, while traditional manual on-site investigation is time-consuming and labor-intensive, and the monitoring function of the metering system is insufficient. This product integrates advanced HPLC communication technology, ARM hardware processor, professional-level real-time LINUX embedded independent software design, high-precision power metering, and simultaneous data comparison to analyze and investigate line loss abnormalities based on data obtained from slave and master devices. The product can simultaneously use multiple devices on the same phase line to further study the location and possible causes of high line loss. When it is applied to low-voltage distribution networks, the device can monitor the load of the area line to achieve transformer-branch box-meter box grading, phase-by-phase line loss analysis and warning functions. It has functions such as HPLC self-organizing network communication, power metering, anti-theft monitoring, and simultaneous line loss comparison, ensuring the location of high line loss. It can accurately and intelligently judge high-loss areas on the spot, moving towards a new high-quality, efficient, and digital line loss abnormality investigation work mode, achieve lean line loss management of the area and achieve the effect of reducing line loss and increasing efficiency of the power grid.
