变压器油检测试验的重要性!

  变压器油是流动的液体,可充满油箱内部各部件之间的气隙,排除空气,从而防止各部件受潮而引起绝缘强度降低。变压器油在运行中还可以吸收绕组和铁芯产生的热量,起到散热和冷却的作用。
  Transformer oil is a flowing liquid, which can fill the air gap between the components inside the oil tank and eliminate air, so as to prevent the parts from being affected by moisture and reduce the insulation strength. Transformer oil can also absorb the heat generated by winding and iron core in operation, which plays a role of heat dissipation and cooling.
  因此变压器油都需要做检测试验。试验项目一般为耐压试验、介质损耗试验和简化试验。
  Therefore, the transformer oil needs to be tested. The test items are voltage withstand test, dielectric loss test and simplified test.

  变压器油的检验指标包括:1、外观;2、水溶性酸;3、酸值;4、闭口闪点;5、介质损耗因数;6、微量水分;7、绝缘强度;8、体积电阻率;9、油中溶解气体分析。如果使用在高压上的油还要做含气量试验。
  The inspection indexes of transformer oil include: 1. Appearance; 2. Water soluble acid; 3. Acid value; 4. Closed flash point; 5. Dielectric loss factor; 6. Trace moisture; 7. Insulation strength; 8. Volume resistivity; 9. Analysis of dissolved gas in oil. If the oil is used on high pressure, air content test is also required.
  所以加强对变压器油化验技术的重视程度,不断优化变压器油化验技术水平,可以改善变压器油对供电设备的保障,促使电力供应系统运行水平的提高。
  Therefore, to strengthen the importance of transformer oil test technology and continuously optimize the technical level of transformer oil test can improve the protection of transformer oil to power supply equipment and promote the operation level of power supply system.
