摘要
油中溶解气体分离是变压器故障气体监测的一个核心环节.在传统顶空脱气法的基础上,提出一种新的顶空脱气的实现方法———"潮汐式"顶空脱气法,设计并搭建基于该设想的实验平台,该平台包括变压器油箱模拟装置、PAS气体检测单元以及脱气装置.在该平台上测试"潮汐"顶空脱气装置对典型故障气体C2H2和CO2的脱气性能,结果表明,该脱气方法可以在150min以内分离溶解在变压器油中的C2H2和CO2,远远优于传统膜分离方法十几小时甚至数天的平衡时间.
The separation of gases dissolved in insulation oil is an important part of power transformer fault gases on-line monitoring. A new headspace oil-gas separation method＂The tide type headspace oil-gas separator＂ is demonstrated and the experimental platform is built in this paper. The platform includes three parts： transformer simulation unit, photo acoustic spectroscopy gas detection unit and oil-gas separation unit. The degassing performance for acetylene and carbon dioxide of this separator is tested with the platform. The experiment results show that the balance time for acetylene and carbon dioxide by using this separator （shorter than 150 min） is several times shorter than traditional polymer membranes and can basically satisfy the requirements of on-line monitoring.
