油色谱载气余量在线监测系统设计

摘要

The transformer is the core equipment in substation, to strengthen the monitoring of the operation of the transformer to ensure the reliability of its operation, to enhance the reliability of power supply system reliability and stability is of great significance. Transformer oil chromatographic on-line monitoring is the transformer condition monitoring technology is mature and the most common means, at present most of the oil chromatographic on-line monitoring equipment is still a gas cylinder carrying, loading cylinder replacement is day-to-day maintenance of the key. In this paper, gas monitoring and analysis of gas cylinders are designed to provide a basis for the replacement of the carrier gas cylinders and the maintenance of the equipment.%变压器是变电站中的核心设备，加强对变压器运行情况的监测力度，确保其运行的可靠性，对提升电力系统供电可靠性和运行的稳定性意义重大。变压器油色谱在线监测是变压器状态监测中技术成熟且最为常见的手段，目前油色谱在线监测大部分设备仍然带有载气瓶，载气瓶的更换是日常维护的重点。本文针对载气瓶的气体监测、分析，设计了变压器载气余量监测系统，为载气瓶的更换和设备的状态检修提供了依据。
