变压器油安全运行的试验分析!

发布时间2019-02-20  来源:http://cqbrk.cn

  常用的变压器油有国产I-10℃(老标准25#)、I-40℃(老标准45#)两种。在油浸式变压器中,变压器油既是绝缘介质,又作为冷却介质。因此,变压器油质量的优劣直接影响到变压器的运行质量。变压器油提醒新的和运行中的变压器油都需要做试验,以保证变压器安全可靠运行。
  Commonly used transformer oil includes domestic I-10 ℃ (old standard 25 × 3) and I-40 ℃ (old standard 45 × 3). In oil immersed transformer, transformer oil is both insulation medium and cooling medium. Therefore, the quality of transformer oil directly affects the operation quality of transformer. Kaiao transformer oil reminds the new and operating transformer oil to be tested to ensure the safe and reliable operation of the transformer.
  一、变压器油的试验
  1、 Test of transformer oil
  1、耐压试验。测量油的介质强度,它是指试油器两电极间油层击穿时电压表所显示的最小值。击穿电压的高低说明油中水、杂质的含量。一般要求介质强度愈高愈好。
  1. Voltage withstand test. Measure the medium strength of oil, which refers to the minimum value displayed by the voltmeter when the oil layer between two electrodes of the oil tester breaks down. The breakdown voltage indicates the content of water and impurities in the oil. Generally, the higher the medium strength is, the better.

  2、介质损耗试验。在外加电压作用下测量绝缘介质中功率损耗的数值,它反映出油质的好坏及净化程度,一般要求介质损失角正切值在20℃时≤0.5%。
  2. Dielectric loss test. Under the action of applied voltage, the value of power loss in insulating medium is measured, which reflects the quality of oil and the degree of purification. Generally, the tangent value of dielectric loss angle is required to be ≤ 0.5% at 20 ℃.
  3、简化试验。为了掌握变压器油运行的情况,一般仅作如下简化试验项目:酸价试验KOH新油的标准≤0.05mg/g,运行中的油应≤0.4mg/g。耐压试验同前述。闪点试验一般在130~140℃。游离碳,机械混合物,最好没有。新油的酸碱度pH值一般为5.4~5.6。
  3. Simplify the test. In order to master the operation of transformer oil, the following simplified test items are generally made: the standard of KOH new oil in acid value test is ≤ 0.05mg/g, and the oil in operation is ≤ 0.4mg/g. The voltage withstand test is the same as above. The flash point test is generally 130 ~ 140 ℃. Free carbon, mechanical mixture, preferably not. The pH value of new oil is generally 5.4-5.6.
