【摘要】 分析了变压器油净化时的油液裂解现象,研究了变压器油真空净化过程中产生气体的影响因素即变压油流动带电放电、气泡相油液的相变能量转换和净油机故障等。根据理论研究的结果,提出了改进真空状态下变压器油流动方式的方案并应用到136台真空净油机上,从而有效降低了真空净化过程中变压器油的裂解程度。更多还原

【Abstract】 According to analysis of transformer oil cleavage in vacuum purifying by 8 sets vacuum oil purification machines,this paper studies factors of gases release in this process: transformer oil flowing electrification,energy radiation of bubble phase conversion and malfunction of oil purification machine.In accordance with the theoretic research,transformer oil flowing mode is improved under vacuum condition and applied to 136 sets vacuum oil purification machines.The results indicate that improvement can reduce transformer oil cleavage in vacuum purification.更多还原
