变压器器油采取油样有哪些要求?

发布时间2019-08-27  来源:http://www.wunqdctk.com

  取油样要求
  Oil Sampling Requirements
  1)当天气干燥时,采集油样必须由在这一领域有经验的受过专门训练的专业人员进行。
  1) When the weather is dry, oil samples must be collected by specially trained professionals with experience in this field.
  2)油样瓶为500~1000ml带研磨塞的玻璃瓶,事先清洗干燥(蒸馏水冲洗)。
  2) Oil sample bottles are 500-1000ml glass bottles with abrasive stoppers, which are cleaned and dried beforehand (washed with distilled water).
  3)油样瓶上应标明设备名称、采样日期、采样器名称、油温、空气湿度、电压等级、相位、编号、采样位置等。
  3) The name of equipment, sampling date, name of sampler, oil temperature, air humidity, voltage level, phase, number and sampling position should be marked on the oil sample bottle.
  4)对于色谱检测,应按照检测方法的要求进行采样。
  4) For chromatographic detection, sampling should be carried out according to the requirements of detection methods.
  5)变压器抽样时要从阀门的下部取样,取样气体用干净的抹布擦拭,再把油冲洗,然后把油冲洗油样品瓶至少两次,然后直接油瓶子(软管应使用中间,滤纸或其他容器,工具和其他过渡),样品瓶必须填写,不得有空间,然后用软木塞盖严,清洁后标签。
  5) Transformer sampling should be taken from the lower part of the valve. The sampled gas should be wiped with a clean cloth, then the oil is washed out, then the oil sample bottle should be washed at least twice, and then the direct oil bottle (hose should be used in the middle, filter paper or other containers, tools and other transitions). The sample bottle must be filled in, no space should be allowed, and then sealed tightly and cleaned with cork stopper. Clean label.
  6)很难从套管带油样品,所以可以把样本套管使用棉签和塑料管道的顶部(或橡胶管道),但它是不可能与一个工具使用多个套管样品,以免影响测试的准确性。
  6) It is difficult to take oil samples from the casing, so the sample casing can be used with cotton swabs and the top of plastic pipe (or rubber pipe), but it is impossible to use multiple casing samples with one tool to avoid affecting the accuracy of the test.

  7)在抽样时,油温的不同样品瓶和样品生产设备不应大于3 - 5℃,尤其是在冬天,热油在变压器应注入油样品瓶,让它温暖,那么应该倒出油,产品样品应立即充满了样品瓶。将从室外到室内的空油样瓶装满油,密封好,保存3 ~4小时,待温度达到室温后才能打开瓶塞。
  7) When sampling, different sample bottles with different oil temperature and sample production equipment should not be greater than 3 - 5 C. Especially in winter, hot oil should be injected into the transformer sample bottle to make it warm, then oil should be poured out, and product samples should be filled with sample bottles immediately. Fill the empty oil sample bottle from outdoor to indoor with oil, seal well and keep for 3 to 4 hours. The cork can not be opened until the temperature reaches room temperature.
  8)油样数量:新油验收LKG(简化试验),2kg(全分析试验),耐压试验0.5kg,色谱分析200-300ml(满瓶)。
  8) Oil sample quantity: new oil acceptance LKG (simplified test), 2kg (full analysis test), pressure test 0.5kg, chromatographic analysis 200-300ml (full bottle).
  9)为使油样反映实际情况,在采样过程中,油样不应与水分接触,采样容器及连接管应保持清洁干燥。
  9) In order to make the oil sample reflect the actual situation, during the sampling process, the oil sample should not contact with water, and the sampling container and connecting pipe should be kept clean and dry.
  10)从设备底部的取样阀上取下取样位置,使所提取的油样能够代表设备本身的油品质量。不允许在油净化器而不是变压器本身取样。
  10) Remove the sampling position from the sampling valve at the bottom of the equipment so that the extracted oil sample can represent the oil quality of the equipment itself. Sampling is not allowed in the oil purifier, not in the transformer itself.
  11)事故取样,如变压器突然失败,使气体继电器之旅后,如立即采取样本在这个时刻,由于气体的传播尚未完全,只有从底部的变压器采样代表性较差,同时在上、下两部分分别取样,最好在4 ~ 8 h的突然失败后再次取样。还要对气体继电器中的气体取样(如果存在气体)。
  11) Accident sampling, such as the sudden failure of transformer, makes the gas relay take samples immediately after the trip. At this time, because the gas transmission is not complete, only sampling from the bottom transformer is less representative. At the same time, the upper and lower parts are sampled separately. It is better to take samples again after the sudden failure of 4 to 8 hours. The gas in the gas relay is also sampled (if there is gas).
