摘要
大型变压器容量的不断增加,而设备各部位绝缘距离则逐渐减小,油中颗粒对变压器绝缘会产生重要影响。许多实例证明有一定数量变压器的故障是因油品颗粒度含量较大引起的。从对多台变压器油中颗粒度测试数据可知,我国变压器颗粒度的水平和国外差距较大。多方面的分析颗粒度对绝缘的影响有利于提高绝缘油的颗粒度检测水平,对保证大型变压器的安全运行有着重要意义。
Management guideline, operation and maintenance practice of transformer oil say it is important to keep the oil cleanness within standard. To ensure the oil insulation property it is necessary to upgrade the granularity measurement level of transformer oil by analyzing different effects of particles in oil.
