变压器油油温异常是怎么回事?

发布时间2019-07-04  来源:http://www.wunqdctk.com

  变压器油温异常:发如今正常条件下,油温比平常高出10摄氏度以上或负载不变而温度不时上升(在冷却安装运转正常的状况下),则可判别为变压器内部呈现异常。
  Transformer Oil Temperature Abnormality: Under normal conditions, the oil temperature is higher than 10 degrees Celsius or the load is unchanged and the temperature rises from time to time (under normal conditions of cooling installation and operation), which can be distinguished as abnormality in the transformer.
  主要为:
  Mainly as follows:
  一、 内部毛病惹起温度异常。
  1. Internal faults cause abnormal temperature.
  其内部毛病,如绕组砸间或层间短路,线圈对围屏放电、内部引线接头发热、铁芯多点接地使涡流增大过热,零序不均衡电流等漏磁经过与铁件油箱构成回路而发热等要素惹起变压器温度异常。发作这些状况时,还将随同着瓦斯或差动维护动作。毛病严重时,还有可能使防爆管或压力释放阀喷油,这时应立刻将变压器停用检修。
  Its internal faults, such as winding interruption or interlayer short circuit, coil discharging to fencing screen, internal lead joint heating, multi-point grounding of iron core, increase eddy current overheating, zero-sequence unbalanced current heating through the circuit with iron fuel tank and other elements cause transformer temperature anomaly. These conditions will be accompanied by gas or differential maintenance actions. When the fault is serious, it may also cause the explosion-proof tube or pressure relief valve to inject oil. At this time, the transformer should be immediately shut down for maintenance.
  二、 冷却器运转不正常所惹起的温度异常。
  2. Temperature abnormality caused by abnormal operation of cooler.
  冷却器运转不正常或者发作毛病,如潜油泵停运、风扇损坏、散热器管道积垢、冷却效果不佳、散热器阀门没有翻开、温度计指示失灵等诸多要素惹起温度升高,应对冷却器系统停止维护和冲洗,以进步其冷却效果。
  Cooler operation is abnormal or breaks down, such as submersible pump shutdown, fan damage, radiator pipe fouling, poor cooling effect, radiator valve not turned over, thermometer indication failure and many other factors cause temperature rise, the cooling system should be stopped maintenance and flushing to improve its cooling effect.

  变压器绝缘油油位异常剖析:
  Analysis of Oil Level Abnormality of Transformer Insulation Oil:
  变压器在运转过程中油位异常和渗漏油现象比拟普遍,应不定期的停止巡视与检查,其中主要表现为以下两方面。
  The abnormal oil level and oil leakage are common in transformer operation, so inspection and inspection should be stopped from time to time, mainly in the following two aspects.
  一、 假油位:油标管梗塞;油枕吸管器梗塞;防爆管道气孔梗塞。
  Firstly, false oil level: obstruction of oil standard pipe; obstruction of oil pillow suction pipe; blowhole obstruction of explosion-proof pipeline.
  二、 油面低:变压器严重漏油;工作人员因工作需求放油后未能及时补充;气温过低且油量缺乏,或是油枕容量偏小未能满足运转的需求。
  2. Low oil level: serious oil leakage of transformer; staff fail to replenish in time after oil discharge due to work needs; low temperature and lack of oil, or small capacity of oil pillow fails to meet the operation needs.
