摘要
某特高压换流站800kV换流变呼吸器在运行过程中发生漏油,停电后现场解体检查发现储油柜内部胶囊破损,开展呼吸器漏油分析和虹吸效应机理分析,确定漏油原因为胶囊破损导致内部进油,在高温大负荷期间达到虹吸效应的激发条件,导致胶囊内部进入的油经呼吸器管路流出,并结合分析结果对后续换流变胶囊运维检修提供建议.
Abstract
Oil leakage occurred during the operation of 800 kV rheological respirator in an UHV converter station.After power failure,on-site disassembly inspection found that the capsules inside the oil storage tank were damaged.The analysis of oil leakage and mechanism of siphon effect were carried out on the respirator,and the cause of oil leakage was determined to be internal oil intake caused by capsule damage,which reached the excitation conditions of siphon effect during high temperature and heavy load.The oil entering the capsule flowed out through the respirator pipeline,and combined with the analysis results,suggestions were provided for the subsequent operation and maintenance of rheological capsules.
