变压器出现缺油时的解决办法

来源:https://www.jnwdsh.com/ 日期:2020-05-19 发布人:admin
油浸变压器内填充的变压器油,一方面可以增加变压器内部各部件间的绝缘强度,使变压器绕组的铁芯得到冷却;另一方面还能使变压器内的绝缘材料,如木质、纸等保持原有的化学和物理性能,使金属,如铜得到防腐;再一方面还能起到熄灭电弧的作用。因此,变压器油所起到的作用主要是散热、防潮及防劣化。
Oil filled transformer oil immersed transformer, one can increase the insulation strength between each component inside the transformer, the core of the transformer winding cooling; on the other hand can make the insulation in the transformer, such as wood, paper and so on to maintain the original chemical and physical properties, metal, such as copper corrosion; on the other hand can to extinguish the arc effect. Therefore, the role of transformer oil is mainly heat dissipation, moisture-proof and anti deterioration.
一、变压器缺油的原因
Transformer oil shortage reasons
1、修理或试验时从变压器内放油后未补充油。
1 、 when repairing or testing, no oil is added after the oil is released from the transformer.
2、长期渗、漏油或大量跑油。
2, long-term seepage, oil spills or a lot of running oil.
3、气温过低而油枕储油量又不足,或者油枕容积小不能满足运行要求。
3, the temperature is too low, and the oil storage capacity of oil pillow is insufficient, or the oil pillow volume is small, can not meet the operation requirements.


二、变压器缺油的后果
Two, transformer oil shortage consequences
1、油面下降到油位计监视线以下,可能造成瓦斯保护装置误动作,并且也无法对油位和油色进行监视。
1, oil drop of oil to the prison below the line, may cause the gas protection device malfunction, and are not on the oil level and oil monitoring.
2、油面下降到变压器顶盖之下,将增大油与空气的接触面积,使油极易吸收水分和氧化,从而加速了油的劣化。潮气进入油中,会降低绕组的绝缘强度,使铁芯和其他零部件生锈。
2, the oil surface down to the lower cover of the transformer, will increase the oil and air contact area, so that oil easily absorb moisture and oxidation, thereby speeding up the deterioration of the oil. When moisture enters the oil, it reduces the insulation strength of the winding and makes the core and other parts rusty.
3、因渗漏而导致严重缺油时,变压器的导电部分对地和相互间的绝缘强度将大大降低,遭受过电压时极易击穿。
3, due to leakage and lead to serious oil shortage, the transformer's conductive parts of the ground and the insulation between the intensity will be greatly reduced, when subjected to over-voltage easily breakdown.
4、变压器油不能浸没分接开关的,分接头之间会泄漏放电而造成高压绕组短路。
4, transformer oil can not be immersed in the tap switch, the leakage between the taps will result in high voltage winding short circuit.
5、油面低于散热管的上管口时,油就不能循环对流,使变压器温升剧增,甚至烧坏变压器。
5, when the oil level is lower than the upper nozzle of the heat radiation tube, the oil can not be circulated and convection, so that the temperature rise of the transformer is greatly increased, and even the transformer is burnt out.
三、变压器出现缺油现象,通常采取的解决措施:
Three, transformer oil shortage occurs, the usual measures taken:
1、如因天气突变,温度下降造成缺油,可关闭散热器并及时补充油。
1, if the weather changes suddenly, the temperature drops, causes the lack of oil, may turn off the radiator and in time supplements the oil.
2、若大量渗、漏油,可根据具体情况,按规程规定采取相应措施。
2, if a large number of seepage, oil spills, according to specific circumstances, according to regulations, to take appropriate measures.
