变质的变压器油的及时处理方式

(1)变压器油检验。对设备带来的变压器油和每批新到的补充油均应有检验报告作为依据。现场还应取样作简化试验。项目为:闪点、绝缘强度,酸价、水溶性酸碱、游离碳、水分和机械混合物。如分析结果中绝缘强度不合格,可以进行过滤,直至耐压合格为止。油的耐压试验是油处理过程中经常进行的。
(1) transformer oil test. The transformer oil and every new batch of supplementary oil to the equipment shall be provided as the basis for the inspection report. Field sampling shall also be taken as a simplified test. Project: flash point, insulation strength, acid value, water soluble acid, free carbon, water and mechanical mixture. If the insulation strength is not qualified in the analysis result, the filter can be filtered until the pressure resistance is qualified. The oil pressure test is often carried out in the oil treatment process.
(2)变压器油取样。取油样的瓶最好选用500ml的毛玻璃口瓶,仔细洗刷干净,取样前置于烘箱内烘干,取样时应取至箱底或桶底,先开启放油阀,冲去阀口赃物,再将取样瓶用油冲洗二次,然后装满油,再将瓶塞塞好。如要送往外地,应将瓶包扎后用腊封严。
(2) transformer oil sampling. Frosted glass bottle oil sampling bottle of the best selection of 500ml, carefully wash clean sampling in front of the oven drying, when sampling should be taken to the bottom or the bottom of the barrel, first open the drain valve, the valve port rushed to the stolen goods, then sampling bottle oil washed two times, and then filled with oil, then the stopper plug good. If you want to send to the field, you should seal the bottle and seal it with wax.
(3)滤油方法。通用的过滤方法有压力过滤法、离心分离法和真空喷雾法三种。
(3) oil filtration method. The common filtration methods are pressure filtration method, centrifugal separation method and vacuum spray method of three kinds.
1)压力过滤器是使用压力滤油机,用油泵压力迫使油通过滤纸除去其中赃物和水分。
1) the pressure filter uses a pressure oil filter, which uses the pressure of the oil pump to force the oil through the filter paper to remove the stolen goods and moisture.

2)离心分离法是使用离心式滤油机,利用离心力将密度大于油的水分和杂质从油中分离出去。除水分外,油中所含污杂物的比重一般于油相差不太多,因而需要提高转数,以加强分离的能力。
2) centrifugal separation is the use of centrifugal oil filters, the use of centrifugal force will be greater than the density of oil moisture and impurities separated from the oil. In addition to water, the proportion of contaminants contained in the oil is generally less than that of the oil. Therefore, it is necessary to increase the number of revolutions to enhance the ability of separation.
3)真空滤油机使油在高真空和不太高的温度下滤出油中微量水份和气体。当热油经真空罐的喷雾管,喷出极细的雾滴后,油中水份(包括气体)便在真空状态下因蒸发而被负压抽出,而油滴落下又回到下部油室由出油泵排除。抽出的水蒸气经冷却器和分水器冷凝、析出;在真空容器内油中的气体随着抽真空的过程排出;同时在真空滤油机里配有粗、精过滤器,用以清除油中杂物。110kv变压器滤油要用真空滤油机进行,以保证变压器油的含水量达到20ul/l(ppm)。
3) vacuum oil filters allow oil to filter out trace amounts of water and gas at high vacuum and at very high temperatures. When the oil tank through vacuum spray pipe, spraying fine droplets, water in oil (gas) in the vacuum state by evaporation by negative pressure exhaust, and oil dropped back to the lower oil chamber by a pump out. Taking the water vapor through the cooler and water separator condensation and precipitation; in a vacuum container in the oil gas process with vacuum discharge; at the same time with the coarse and fine filter in the vacuum oil filter machine, used to remove oil in debris. 110kV transformer oil filter should be carried out with a vacuum oil filter to ensure that the water content of transformer oil reaches 20ul/l (ppm).
