怎么做到不同油号的变压器油不混合的呢?

发布时间2019-04-16  来源:http://www.wunqdctk.com

变压器油在变压器和油开关设备中起着非常重要的作用,为防止不同油号的变压器油误混合,要注意做到一下几点,具体如下:
  Transformer oil plays a very important role in transformer and oil switch equipment. In order to prevent mismixing of transformer oil with different oil numbers, we should pay attention to several points, as follows:
  一、对电网已运行的变压器要逐台建立设备档案。对原生产厂以及在变压器大修后的变压器油油号要有记录。
  First, equipment files should be set up one by one for transformers that have been operated in the power grid. The oil number of the original manufacturer and transformer after overhaul should be recorded.
  二、从购入的变压器原油到经过滤后的变压器油都要用专用油号的油罐储存。
  2. From the transformer crude oil purchased to the transformer oil filtered, the oil tank with special oil number should be used for storage.
  另外,对运行变压器中加补变压器油应注意:
  In addition, attention should be paid to adding transformer oil to the running transformer.
  1、新补入变压器油应经各项试验合格。
  1. The newly added transformer oil shall pass all tests.
  2、补油前将重瓦斯保护改接信号位置,防止误动作掉闸补油后瓦斯继电器应及时放出气体,待经24h无问题后可将重瓦斯接入掉闸位置。
  2. Change the heavy gas protection to the signal position before refueling, so as to prevent the misoperation of the gas relay after refueling, the gas relay should release the gas in time, and the heavy gas can be connected to the refueling position after 24 hours without any problems.
  3、补加的变压器油油量及变压器油油位要适宜。
  3. The amount of transformer oil added and the level of transformer oil should be appropriate.
  4、禁止从变压器底部活塞加油,防止将底部沉淀物冲起进入线圈,影响变压器绝缘和散热。
  4. It is forbidden to refuel the piston at the bottom of the transformer to prevent the bottom sediment from rushing into the coil and affecting the insulation and heat dissipation of the transformer.
  5、不同牌号的变压器油一般不宜混合使用,最好使用同一牌号的油品,以保证原来运行油的质量和明确牌号特点。

  5. Transformer oils of different grades are generally not suitable for mixed use. It is better to use the same brand of oil to ensure the quality of the original operating oil and to clarify the characteristics of the brand.
  由于变压器油是按倾点或凝点以及油品的低温性能划分种类,一般是根据设备种类和使用环境温度选用的,选用同一牌号就可保证其运行特性基本不变,且维持设备技术档案中用油的统一性。
  Because transformer oil is classified according to pour point or condensation point and low temperature performance of oil products, it is usually selected according to equipment type and operating environment temperature. The same brand can ensure that its operation characteristics remain basically unchanged and the uniformity of oil used in equipment technical files is maintained.
  不同的变压器油的油基和工艺过程不一定相同。变压器油的化学成分为饱和碳氢化合物,其油基有石蜡基、芳香基、环烷基、混合基等几种,不同的油基有不同的老化程度,因此不能混用。同一油基不同油号的油可以混用,但混用后其理化性能降低。不同工艺过程的油混用也会影响其绝缘电阻。因此混用前应经过混油试验合格后方可使用。
  The oil base and process of different transformer oils are not necessarily the same. The chemical composition of transformer oil is saturated hydrocarbon. Its oil base includes paraffin base, aromatic base, naphthenic base and mixed base. Different oil base has different aging degree, so it can not be mixed. Oils of the same base and different grades can be mixed, but their physical and chemical properties will be reduced after mixing. Oil mixing in different process also affects its insulation resistance. Therefore, before mixing, it should pass the mixing test before it can be used.
