油中溶解气体在线监测系统全自动气源模块分析

Analysis of automatic Gas Source Module For on-line Monitoring System of Dissolved Gas in oil

对于电力设备实施状态检修而言,油色谱在线监测系统是一个非常靠谱的手段,在保障变压器安全稳定运行中发挥着重要作用。油中溶解气体在线监测装置需要使用消耗性载气,一般一台色谱在线每天做样一次,平均一年消耗两瓶载气,更短的分析周期,则需要更多的载气。更换载气,形成了较大的工作量,耗费人力、物力、财力。本文针对目前油色谱在线监测系统的这一问题,研制一套油中溶解气体在线监测装置专用气源模块,利用就地净化的空气作为载气,可为油中溶解气体在线监测装置提供源源不断的载气,实现真正意义上的油色谱在线监测系统免维护。

The oil chromatography online monitoring system is a very reliable means for the maintenance of power equipment. It plays an important role in ensuring the safe and stable operation of the transformer.On-line monitoring devices for dissolved gases in oil require the use of consumable carrier gas.Generally,one chromatographic line is sampled once a day,consuming an average of two bottles of carrier gas per year.For a shorter analysis cycle,more carrier gas is required.The replacement of the carrier gas has resulted in a large workload,which requires manpower,material resources and financial resources.Aiming at the current problem of oil chromatography online monitoring system,a set of gas source module for on-line monitoring device for dissolved gas in oil is developed. By using the purified air as carrier gas,it can provide a continuous carrier gas for the on-line monitoring device of dissolved gas in oil.To achieve real maintenance of oil chromatography online monitoring system maintenance-free.
