消除变压器油中气泡的相关措施

  纯净油的击穿场强很高,当油中存在杂质和水分时,油的击穿电压明显下降。变压器中有大量的绝缘材料,而油中含有纤维杂质,其中含有水分的纤维更易导电。

  The breakdown field of pure oil is very high. When there are impurities and moisture in the oil, the breakdown voltage of the oil drops obviously. There are a lot of insulating materials in the transformer, and the oil contains fiber impurities, in which the fiber containing water is more conductive.

  降低油的含水量对提高变压器运行安全及减缓油老化有重要作用。为了降低油的含水量,可以采取对油进行真空加热法处理,油温加热到60~70℃,抽高真空,将油中的含水量降下来。

  Reducing the water content of oil plays an important role in improving the operation safety of the transformer and slowing down the aging of oil. In order to reduce the water content of the oil, vacuum heating can be used to treat the oil. The oil temperature is heated to 60~70 degrees, and the high vacuum is pumped to reduce the water content in the oil.

  含气量是变压器油的主要控制指标之一,含气量直接影响超高压变压器的绝缘性能。运行中变压器油含气量最好不超过4%,500kv变压器油含气量控制在0.5%以内。60kv级以上变压器要求进行真空注油和成品试验前的静放处理,其目的就是为了消除变压器器身内部和油中气泡,防止产品试验时发生气泡放电。

  The gas content is one of the main control indexes of transformer oil, and the gas content directly affects the insulation performance of the ultra high voltage transformer. The oil content of the transformer oil in operation is best not more than 4%, and the gas content of 500kV transformer oil is controlled within 0.5%. Transformers above grade 60kV require static discharge before vacuum injection and finished products test. The purpose is to eliminate bubbles in the transformer body and oil and prevent bubble discharge during product test.

  改善电场的均匀程度可以明显提高优质变压器油的工频击穿电压。对于含有杂质的油在冲击电压作用下,杂质来不及形成“小桥”,改善电场的均匀程度可以提高油的耐压程度。

  Improving the uniformity of the electric field can obviously improve the power frequency breakdown voltage of the high quality transformer oil. As for the oil containing impurities, the impurity can not form a "small bridge" under the impact voltage, and the degree of pressure resistance of the oil can be improved by improving the uniformity of the electric field.
