确保变压器的安全运行的实验基础

  油的散热主要取决于油的黏度及变压器的外形结构,其中降低油的黏度对提高设备的散热能力实际意义并不大,而变压器的散热面积和冷却方式,对提高变压器的散热能力具有很大的实际意义。

  The heat dissipation of oil depends mainly on the viscosity of the oil and the configuration of the transformer. Reducing the viscosity of oil is of little practical significance to improving the heat dissipation capacity of the equipment, and the heat dissipation area and cooling mode of the transformer have great practical significance to improve the heat dissipation capacity of the transformer.

  油浸变压器内的变压器油,一方面可以增加变压器内部各部件间的绝缘强度,使变压器绕组的铁芯得到冷却;另一方面还能使变压器内的绝缘材料,如木质、纸等保持原有的化学和物理性能,使金属,如铜得到防腐;再一方面还能起到熄灭电弧的作用。因此,凯奥变压器油所起到的作用主要是散热、防潮及防劣化。

  On the one hand, the transformer oil in the oil immersed transformer can increase the insulation strength between the parts of the transformer, and make the core of the transformer winding cool; on the other hand, the insulation material in the transformer, such as wood and paper, can keep the original chemical and physical properties, so that the metal, such as copper, can be antiseptic. It can also play the role of extinguishing the arc. Therefore, Koh transformer oil plays a major role in heat dissipation, moisture prevention and deterioration prevention.

  变压器油在运行中,长期受高温的影响和电场及化学复分解的作用,也会使油质发生劣化。

  During the operation of transformer oil, the influence of high temperature and electric field and chemical decomposition will also cause deterioration of oil quality.

  油在运行中可能与空气接触,空气中的水会使油受潮。受潮后的油,不仅导致击穿电压降低、介质损耗增加,而且加速变压器中铜、铁等材料的氧化作用,引起油中大量的沉淀物生成。一般氧化的油又比新鲜的油更易受潮,而受潮的油与干燥的油相比其老化速度要快2~4倍。

  Oil may be in contact with air in operation, and the water in the air will damp the oil. The oil after moistening not only reduces the breakdown voltage and the dielectric loss, but also accelerates the oxidation of copper and iron in the transformer, and causes a large amount of sediment in the oil. Generally, oxidized oil is more susceptible to moisture than fresh oil, and the wetting oil is 2~4 times faster than the dry oil.

  变压器在运行中除应对油采取有关保护措施外,还应定期取样试验,以对油质进行监视,确保变压器的安全运行。

  In addition to the relevant protection measures for the oil in operation, the transformer should also be regularly sampled to monitor the oil quality and ensure the safe operation of the transformer.
